Image Acquisition

This chapter gives detailed information about the controlling of the image acquisition. It shows how the camera can be triggered or run in free-running mode, and how the frame rate can be conﬁgured.

The structure offers a lot of ﬂexibility in the conﬁguration. It follows the GenICam naming convention. Typical camera conﬁgurations are included in the chapter "Use Cases" in the Appendix C.

4.1 Overview

The overview shows the major camera elements which are involved in the image acquisition. The section starts with a description of the vocabulary and terms, which are used to explain the acquisition related features.

4.1.1 Vocabulary

An acquisition is composed of one or many frames. A frame is a single acquired image which consists of an exposure time and an image read out. A burst of frame is deﬁned as a capture of a group of one or many frames within an acquisition. An acquisition can be grouped in N single frames or N burst of frames.

4.1.2 Structure

The image acquisition is controlled by the three sub-blocks acquisition control, frame control and exposure control. Furthermore the camera contains controller blocks which take care of the I/O signals, the counters, the timers, the action signals, the software signals and the user outputs. All of these elements can be connected through an interconnect, which allows controlling the image acquisition by these elements.

Figure 4.1: Structure

MAN078 12/2018 V1.1 21 of 111

4 Image Acquisition

Acquisition Control The acquisition control block takes care of the acquisition function. The

camera can only capture frames, when the acquisition has been started and is active (see Section 4.2 for more information).

Frame Control The frame control block takes care of the capturing of one or many frames and

burst of frames (see Section 4.3 for more information).

Exposure Control The exposure control block takes care of the exposure time of a frame (see

Section 4.4 for more information).

Counter The camera has four independent counters. They count events from a selectable

source (see Section 5.1 for more information about counter conﬁguration and usage).

Timer The camera has four independent timers. A timer delay and duration are conﬁgurable

and the timers are triggered by a selectable source (see Section 5.2 for more information about timer conﬁguration and usage).

Action There are four actions, which can be used to trigger functions in the GigE camera, such

like aquisition and frame capture or counter and timer. Action commands can be generated by the host application and are transmitted via GigE interface to the camera with low latency and low jitter.

I/O Control The I/O control unit manages physical camera inputs and outputs and LED. A

switch matrix within this block allows connecting internal status signals to the output lines or LED. Status signals can come from the acquisition, frame or exposure control block, also from timer or counter, or even input lines can be routed to an output. The input lines can be used to control the acquisition, frame and/or exposure, also to start a timer or count events with a counter (see Chapter 6 for more information).

Software Signal Pulse and User Output The camera has user outputs, which can be set to 1 or

0 by software access, and a software signal pulse generator block (see Section 4.7). These user outputs and signal pulses can be used to control camera functions by software access, such like acquisition and frame capture or counter and timer.

Signal Routing All these elements are connected to each other by the signal routing block. The

following sections show which signals are available and how they can be used in the others blocks.

4.1.3 Image Acquisition, Frame and Exposure Control Parameters

Mainly the following commands/settings are involved in order to control and conﬁgure the camera acquisition and frame capturing:

• Acquisition Start and Stop Command

• Acquisition Mode (Single Frame, Multi Frame, Continuous Frame)

• Acquisition Frame Count

• Acquisition Frame Burst Count

• Acquisition Frame Rate

• Exposure Mode (Timed, Trigger Controlled)

• Exposure Time

This list shows only an overview of available parameters. The function and usage of them are explained in the following chapters.

22 of 111 MAN078 12/2018 V1.1

4.1 Overview

4.1.4 Image Acquisition, Frame and Exposure Trigger

The camera can run in "free-running" mode, which means that it captures images automatically in full frame rate once the acquisition has been started. However the acquisition and image capturing can be controlled by triggers. For this purposes, there are seven triggers available:

• Acquisition Start Trigger

• Acquisition End Trigger

• Frame Start Trigger

• Frame Burst Start Trigger

• Frame Burst End Trigger

• Exposure Start Trigger

• Exposure End Trigger

The source of these trigger can be set for every trigger individually; it can come from an external line, an internally generated pulse from the counters, the timers, the action signals or from a pulse generated by a software command. Each of these triggers can be switched on or off individually. The camera generates the triggers pulses internally, which are switched off. The following sections (Acquisition, Frame & Exposure Control) show the usage of these triggers.

Each trigger has its own source signal processing path. Section 4.6 gives more information about the conﬁguration.

4.1.5 Image Acquisition, Frame and Exposure Status

The following list shows the acquisition, frame and exposure related status signals:

• Acquisition Trigger Wait

• Acquisition Active

• Frame Trigger Wait

• Frame Active

• Exposure Active

These status signals are used within the camera to control the camera timing. The current state of these signals can be read out by software. Furthermore it can be connected to an output line or LED through the I/O control block (see Chapter 6), which allows tracking the status from an external device. The timing of these signals are explained in the following sections.

4.2 Acquisition Control

Figure 4.2: Acquisition Control Block

4.2.1 Acquisition Start and Stop Commands, Acquisition Mode and Acquisition Frame Count

The camera can only capture frames when the acquisition is started. The acquisition start command, which is executed by the software, starts the acquisition and prepares the camera to acquire frames. The acquisition is stopped, when the acquisition stop command is executed or depending on the acquisition mode parameter - a certain number of frames is captured. Following acquisition mode parameters are available:

Acquisition Mode = Single Frame When the acquisition is started, the camera stops the

acquisition automatically as soon as one frame has been captured. To capture another frame, the acquisition start command needs to be performed again.

Acquisition Mode = Multi Frame When the acquisition is started the camera stops the

acquisition automatically after a certain number of frames, which are deﬁned by acquisition frame count parameter, or when the acquisition stop command is executed.

Acquisition Mode = Continuous Frame When the acquisition is started the camera captures

images continuously until the acquisition stop command is executed.

4.2.2 Acquisition Frame Rate and Acquisition Frame Rate Enable

With frame start trigger mode=off (see Section 4.3.1) and frame burst start trigger mode=off (see Section 4.3.2), and when exposure mode is set to "timed" (see Section 4.4.1), the camera generates frame start triggers internally according to the acquisition frame rate enable and acquisition frame rate conﬁguration:

Acquisition Frame Rate Enable = off The camera runs in the "free-running" mode. It means

frame start triggers are generated internally as soon as the camera is ready to start a new image capture. The frame rate is deﬁned by the exposure time and the ROI settings (see Chapter 9).

Acquisition Frame Rate Enable = on The camera generates frame start triggers internally

according to the acquisition frame rate conﬁguration. See Chapter 9 for more information about the range of supported frame rates.

Fig. 4.3 shows the procedure of a capture of N frames. The modes of acquisition start trigger, frame start trigger and frame burst start trigger is set to off and the exposure mode is timed. Once an acquisition start command has been executed, the camera starts capturing frames until the acquisition stop command is received.

4.2.3 Acquisition Start Trigger

The acquisition start trigger can be used to control the acquisition start procedure. The main property of this trigger is the trigger mode. It can be set to on or off:

Acquisition Start Trigger Mode = on As soon as the acquisition is started by executing of the

acquisition start command, the camera goes into the state "Acquisition Trigger Wait". In this state, the camera can’t start capturing images; it waits for an acquisition start trigger. As soon as the trigger has been received, the camera goes then into the state "Acquisition Active" and is ready to capture frames.

Acquisition Start Trigger Mode = off As soon as the acquisition is started by executing of the

acquisition start command, the camera goes immediately into state "Acquisition Active" and is ready to capture frames.

Fig. 4.4 shows an example when the trigger mode of the acquisition start trigger is on. The acquisition status goes to acquisition trigger wait once an acquisition start command has been executed. As soon as an acquisition start trigger has been arrived, the acquisition status goes to acquisition active.

4 Image Acquisition

4.2.4 Acquisition End Trigger

The acquisition end trigger can be used to control the acquisition end procedure. The main property of this trigger is the trigger mode. It can be set to on or off:

Acquisition End Trigger Mode = on When the acquisition status is "Acquisition Active", it goes

to "Acquisition Trigger Wait" as soon as an acquisition end trigger has been received. The camera stops capturing images and waits until an acquisition start trigger has been issued again.

Acquisition End Trigger Mode = off The acquisition end triggers are ignored and the

acquisition status remains active until an acquisition stop command has been executed or the certain amount of frames has been captured, depending on the acquisition mode parameter (see Section 4.2.1)

4.2.5 Acquisition Control Output Signals

The acquisition control block has the following output signals:

Acquisition Trigger Wait An asserted acquisition trigger wait indicates, that the acquisition

control is waiting for an acquisition start trigger (see Section 4.2.3).

Acquisition Active Acquisition active is a status signal, which is asserted, when the acquisition

has been started and deasserted, when the acquisition is stopped.

Acquisition Start The acquisition start is an event, which is generated, when the acquisition is

started.

Acquisition End The acquisition end is an event, which is generated, when the acquisition is

stopped.

Acquisition Trigger The acquisition trigger is an event, which is generated, when the

acquisition is started by the acquisition start trigger (see Section 4.2.3).

Acquisition trigger wait and acquisition active status signal are routed to the I/O control block and can there be selected for output on the physical output line or on one of the available leds (see Chapter 6). Acquisition start, acquisition end and acquisition trigger event can be used to trigger or to control other function in the camera, like counter or timer.

4.3 Frame Control

Figure 4.5: Frame Control Block

As soon as the acquisition is active the camera is ready to capture frames, which is controlled by the frame control block. The behaviour depends on the frame start trigger, frame burst start trigger and frame burst end trigger conﬁguration.

4.3.1 Frame Start Trigger

The frame start trigger can be used to start a single frame capture. The main property of this trigger is the trigger mode. It can be set to on or off:

Frame Start Trigger Mode = on As soon as a frame start trigger has been received, a capture of

one frame will be started and the frame status goes to "Frame Active". Once one frame has been processed, that camera status goes to "Frame Trigger Wait" again. The camera is ready to process frame start triggers, when the acquisition is active, showed by the "Acquisition Active" status, and when the "Frame Trigger Wait" status is asserted.

Frame Start Trigger Mode = off The frame start triggers are ignored.

The camera runs in free-running mode when the mode of both triggers, the frame start trigger and frame burst start trigger, is set to off and the exposure mode is set to "Timed" (see Section 4.4.1 for more information about the exposure mode).

Fig. 4.6 shows the procedure of a single frame capture started with a frame start trigger. The acquisition start trigger mode is off, so the camera waits for a frame start trigger once the acquisition command has been executed. Every receiving frame start trigger starts a capture of one single frame.

4.3.2 Frame Burst Start Trigger

The frame burst start trigger can be used to start a burst of frame capture. The main property of this trigger is the trigger mode. It can be set to on or off:

Frame Burst Start Trigger Mode = on As soon as a frame burst start trigger has been received,

a capture of a burst of frames has been started and the frame status goes to "Frame Active". The number of frames is deﬁned by the "Acquisition Burst Frame Count" value. The camera goes to "Frame Trigger Wait" again, when the conﬁgured number of burst frames has been captured. The camera is ready to process a frame burst start trigger, when the acquisition is active, showed by the "Acquisition Active" status, and when the "Frame Trigger Wait" status is asserted. The frame rate of a burst sequence is conﬁgured

by the acquisition frame rate value and the acquisition frame rate enable conﬁguration (see Section 4.2.2 for more information)

Frame Burst Start Trigger Mode = off The frame burst start triggers are ignored. No capturing

of burst of frames is started.

It is possible to set both, the mode of frame start trigger and frame burst start trigger, to on. In this case, the camera starts a single frame or a burst of frame capture, depending which trigger arrives ﬁrst.

Fig. 4.7 shows the procedure of a burst of frames and a single frame capture. The Acquisition start and end trigger mode is on. So the camera waits for an acquisition trigger once the acquisition command has been executed. During this period any frame burst start or frame start triggers are ignored. As soon as an acquisition start trigger has been received, the camera waits for frame triggers. It can be a frame start trigger or a frame burst start trigger. Depending which trigger - frame start or frame burst start - arrives ﬁrst, the camera starts a single frame or burst of frame acquisition.

4.3.3 Frame Burst End Trigger

The frame burst end trigger can be used to abort a current running burst capturing cycle. The main property of this trigger is the trigger mode. It can be set to on or off:

Frame Burst End Trigger Mode = on The frame burst end trigger is processed only, when burst

acquisition cycle is active. Once this trigger has been received, it waits, until the current frame has been processed and then aborts the burst cycle. The camera status goes to "Frame Trigger Wait" again.

Frame Burst End Trigger Mode = off The frame burst end triggers are ignored.

The value "Acquisition Burst Frame Count" is ignored when the mode of the frame burst end trigger is set to on. It means, when a burst capture has been started, the camera captures frames until a frame burst end trigger arrives.

4.3.4 Frame Control Output Signals

The frame control block has the following output signals:

4.3 Frame Control

Frame Trigger Wait An asserted frame trigger wait indicates, that the frame control is waiting

for a frame start trigger (see Section 4.3.1), frame burst start trigger (see Section 4.3.2) or an exposure start trigger (see Section 4.4.2).

Frame Active An asserted frame active signal indicates, that one or more frames are being

captured.

Frame Start The frame start is an event, which is generated, when a new frame starts.

Frame End The frame end is an event, which is generated, when a frame is ﬁnished.

Frame Burst Start The frame burst start is an event, which is generated, when a new burst of

frame starts.

Frame Burst End The frame burst end is an event, which is generated, when a burst of frame is

ﬁnished.

Frame Trigger The frame trigger is an event, which is generated, when a frame is started by a

frame start trigger (see Section 4.3.1), by a frame burst start trigger (see Section 4.3.2) or by an exposure start trigger (see Section 4.4.2).

Frame trigger wait and frame active status signal are routed to the I/O control block and can there be selected for output on the physical output line or on one of the available leds. Frame start, frame end and frame trigger event can be used to trigger or to control other function in the camera, like counter and timer.

4.4 Exposure Control

Figure 4.8: Exposure Control Block

A frame consists of an exposure cycle and an image read out. The exposure control block takes care of the exposure cycle. The camera has two modes of exposure time operations, which are deﬁned by the exposure mode settings:

• Timed Exposure

• Trigger Controlled Exposure

4.4.1 Exposure Mode

The exposure mode conﬁguration deﬁnes, if the exposure time is controlled by the exposure time registers or by the triggers. Following conﬁgurations are available:

Timed Exposure The exposure time is deﬁned by the exposure time register. The value will

determine the exposure time for each frame.

Trigger Controlled Exposure The exposure time is controller by exposure start and exposure

end triggers (see Section 4.4.2 and Section 4.4.3 for more information).

4.4.2 Exposure Start Trigger

The exposure start trigger is used to start an exposure.

Exposure Start Trigger Mode = on As soon as a exposure start trigger has been received, the

camera starts with the exposure cycle, which is showed by the "Exposure Active" status. The exposure remains until an exposure end trigger has been received (see Section 4.4.3). The camera is ready to process exposure start triggers, when the acquisition is active, showed by the "Acquisition Active" status, and when the "Frame Trigger Wait" status is asserted.

Exposure Start Trigger Mode = off The exposure start triggers are ignored.

The exposure start trigger is only available, when the exposure mode is set to "trigger controlled". The camera sets the trigger modes of this trigger automatically to on, when the exposure mode is set to "trigger controlled" and vice versa to off when the exposure mode is set to "timed".

4.4.3 Exposure End Trigger

The exposure end trigger is used to terminate an active exposure cycle.

Exposure End Trigger Mode = on An activated exposure cycle will be terminated and the

image read out will be started, as soon as an exposure end trigger has been received. The "Exposure Active" status goes to inactive. Exposure end triggers are only processed, when an exposure start trigger has started a trigger controlled exposure cycle previously.

Exposure End Trigger Mode = off The exposure end triggers are ignored.

The exposure end trigger is only available, when the exposure mode is set to "trigger controlled". The camera sets the trigger modes of this trigger automatically to on, when the exposure mode is set to "trigger controlled" and vice versa to off when the exposure mode is set to "timed".

Fig. 4.9 shows procedure of a trigger controlled exposure mode. The Acquisition start trigger mode is off. The camera goes directly into status "Frame Trigger Wait" once the acquisition status has been executed. An exposure of a new frame is started as soon as an exposure start trigger has been received. The exposure ends with an exposure end trigger.

Figure 4.9: Trigger Controlled Exposure Mode

4.4.4 Exposure Control Output Signals

The frame control block has the following output signals:

Exposure Active An asserted exposure active signal indicates, that an exposure time of a

current frame is active.

Exposure Start The exposure start is an event, which is generated, when a new exposure time

has been started.

Exposure End The exposure end is an event, which is generated, when a currently running

exposure time is ﬁnished.

Exposure active status signal is routed to the I/O control block and can there be selected for output on the physical output line or on one of the available leds. Exposure start and exposure end event can be used to trigger or to control other function in the camera, like acquisition, frame and exposure control or counter and timer.

4.5 Overlapped Image Acquisition Timing

The camera is able to perform an overlapped image acquisition. It means, a new exposure can be started during the image readout of the previous image. Fig. 4.10 shows an image acquisition procedure when images are captured in overlapped mode. The status "Frame Active" remains active during the acquisition of the three frames since there is no gap between two frames. The "Frame Trigger Wait" is asserted during the frame read out in order to indicate, that a new exposure can be started.

All examples in the previous sections show a non overlapping frame timing. A new frame is always started after the previous image read out has been ﬁnished. All these examples work also in the overlap mode. It doesn’t show the overlap mode in order to simplify the diagrams.

The overlapped image acquisition is not available, when the triggered controlled exposure mode is conﬁgured.

Figure 4.10: Overlapped Image acquisition Timing

There is a restriction of the overlapped image acquisition: The exposure time of the current frame must not end prior to the end of the read out of the previous frame. Two different timing situation needs to be distinguished:

Exposure Time > Read Out Time An new exposure cycle can be started as soon as the read out

Exposure Time < Read Out Time The start of a new exposure has to be delayed by a certain

The camera adjusts the timing automatically, and ensures that it complies with this restriction.

of the previous frame has been started (See Fig. 4.11).

amount of time in order to ensure, that the exposure doesn’t end prior to the image read out end of the previous frame (See Fig. 4.12).

Frame start or frame burst start triggers which arrive too early and which violates the overlapping restriction, will be ignored by the camera and indicated by a missed trigger event,

5.1 Counter

Figure 5.1: Counter Structure

Four general purpose counters are available (Counter0 . . . Counter3) which are used for counting events. Each counter can be individually conﬁgured by software and controlled by counter trigger, counter event and counter reset signals. This section describes the conﬁguration and the function of the counters.

Fig. 5.1 shows the structure of one counter. Along with the counter function itself it contains a counter trigger source, a counter event source and a counter reset source selection and activation block. Furthermore there is a counter active status signal, which is available in the I/O control block (see Chapter 6). And the counter generates counter start and counter end events, which can be used to trigger other blocks, like counter, timer, acquisition, frame or exposure control.

5.1.1 Counter Usage

In a basic usage, at least a counter event source needs to be selected (see Section 5.1.5 for more information about the counter event source selection). Once an event source has been selected, the counter needs to be reset in order to start the counter. When started it counts from a deﬁned start value, which is conﬁgurable by the CounterStartValue property, and ends counting events after a certain number of events, which is conﬁgurable by the CounterDuration property.

MAN078 12/2018 V1.1 39 of 111

5 Counter & Timer

If additionally a trigger source is selected, the counter is waiting for a trigger. It ignores counter events until a valid trigger event has been received. A valid trigger signal on the selected trigger source starts the counter, which means, that it counts the predeﬁned number of events from the start value according to the counter start value and duration conﬁguration.

The current counter value is readable by the property CounterValue.

5.1.2 Counter Status

The counter has different states, which depends on the conﬁguration and usage. The current state can be read out by the register CounterStatus. The following list shows the available states:

Counter Idle Counter is idle, and doesn’t count any events.

Counter Trigger Wait As soon as a counter trigger source is selected (counter trigger source 6=

OFF), the counter goes into the counter trigger wait state and waits for a trigger signal on the selected source. In this state, the counter does not count any events.

Counter Active Counter is active and is ready to count every event. The counter can be

temporarely stopped by setting the counter event source to OFF .

Counter Completed Counter has stopped as it reached its programmed duration.

Counter Overﬂow Counter has reached its counter limit, which is 2^32-1, and an additional

counter event signal has been received. Once the counter is in the state overﬂow, it has to be reset by software or by counter reset signal in order to recover it from this state.

5.1.3 Counter Active, -Start and -End Signal

Each counter has the following output signals:

Counter Active An asserted counter active signal indicates, that the counter is active and is

counting events. The counter active signal is internally routed to the I/O control block and can there be selected for output on the physical output line or on one of the available leds.

Counter Start The counter start is an event, which is generated, when the counter goes into

the counter active state or is restarted during counter active period.

Counter End The counter end is an event, which is generated, when the counter arrives its

conﬁgured end condition; and changes to the state counter completed.

The counter start and end event can be used to trigger or to control other function in the camera, like acquisition, frame and exposure control or counter and timer. It can also be used to cascade counters in order to get a bigger counting range.

5.1.4 Counter Reset

There are two ways how to reset a counter: Either by a software reset command or by a hardware reset source signal. The reset behaviour depends on the current counter event and trigger source conﬁguration:

Counter Trigger Source = Off and Counter Event Source = Off The state of the counter

changes to "idle".

Counter Trigger Source = Off and Counter Event Source 6= Off The state of the counter

changes to "active".

40 of 111 MAN078 12/2018 V1.1

5.1 Counter

Counter Trigger Source 6= Off The state of the counter changes to "trigger wait".

The counter reset source can be set to the counter end signal of the same counter. This allows to restart the counter automatically as soon as it arrives its end condition.

The current counter value at the time, when the reset is performed, is stored to the CounterValueAtReset property, which can be read out by software.

5.1.5 Counter Event Source

The counter event source selects the signal event, which will be the used to increment the counter. The following signal sources are available:

Off Counter is idle or has been stopped temporarely and doesn’t count any events.

Acquisition Trigger Counts the number of acquisition triggers.

Acquisition Start Counts the number of acquisition start events.

Acquisition End Counts the number of acquisition end events.

FrameTrigger Counts the number of frame triggers.

MAN078 12/2018 V1.1 41 of 111

5 Counter & Timer

MissedFrameBurstStartTrigger Count the number of missed frame burst start triggers. A

missed frame burst start trigger event is generated, when a frame burst start trigger cannot be processed.

MissedExposureStartTrigger Count the number of missed exposure start triggers. A missed

exposure start trigger event is generated, when an exposure start trigger cannot be processed.

Missed Trigger Counts the number of any generated missed triggers. The missed trigger is the

logical OR connection of MissedAcqStartTrigger, MissedFrameStartTrigger, MissedFrameBurstStartTrigger and MissedExposureStartTrigger.

Time Stamp Tick Counts the number of time stamp ticks. A time stamp tick generator is

available for every counter. It generates events with a rate, which can be conﬁgured. For instances if the rate is set to 1 us and the counter event source is set to count time stamp ticks, the counter increments every 1 us.

Line input source has additionally an activation conﬁguration, which needs to be set accordingly. Following conﬁguration values are available:

Rising Edge Counter counts rising edges on the selected line input.

Falling Edge Counter counts falling edges on the selected line input

Both Edges Counter counts both edges on the selected line input

Activation conﬁguration has only effect when line input is selected as a counter event source, otherwise this conﬁguration is ignored.

The counter can be temporarely switched off, if the counter event source is set to off. It continue counting events as soon as counter event source has been selected again.

5.1.6 Counter Trigger Source

The counter trigger source selects the signal which will be used to start the counter. The following signals sources are available:

Four general purpose timers are available in the camera (Timer0 ... Timer3). A timer can be used to generate a timed pulse - for instances a strobe signal - or to generate an event after a predetermined duration. Each timer can be conﬁgured individually by software and controlled by timer trigger events. This section describes the conﬁguration and the function of the timers.

Fig. 5.2 shows the structure of one timer. It contains a timer trigger source and activation block. Furthermore it has three output signals: A timer active status signal, which is routed to the I/O control block (see Chapter 6) and timer start and end event signals, which can be used to trigger other blocks, like counter, timer, acquisition, frame or exposure control (see Section

5.2.3).

Figure 5.2: Timer Structure

5.2.1 Timer Usage

Timer delay and timer duration value needs to be conﬁgured accordingly. When a timer trigger source is selected the timer is waiting for a trigger signal. Once this trigger signal has been received, the timer starts ﬁrst with the timer delay period, if the timer delay value is > 0, and counts then for the speciﬁed timer duration.

When the timer trigger source is set to off (see Section 5.2.5), a software timer reset command starts the timer immediately (see Section 5.2.4).

The current timer value can be read via software. A start value can also be set, which means, that the timer starts from this conﬁgured value instead from zero.

5.2.2 Timer Status

The timer has different states, which depends on the conﬁguration and usage. The current state can be read out by the register TimerStatus. The following list shows the available states:

Timer Idle Timer is idle, and trigger source selection is set to off.

Timer Trigger Wait Timer is waiting for a timer trigger signal.

Timer Delay Timer is in timer delay count period.

Timer Active Time is active and counts for the speciﬁed timer duration.

Timer Completed Timer completed indicates, that the timer reached the timer duration count.

The timer remains in this state, until a new timer trigger event has been received, or the timer is reset by a software command (see Section 5.2.4)

5.2.3 Timer Active, -Start and -End Signal

Timer Active An asserted timer active signal indicates, that the timer has started counting the

conﬁgured duration period. The timer active signal is internally routed to the I/O control block and can there be selected for output on the physical output line or on one of the available leds.

Timer Start The timer start is an event, which is generated, when the timer starts with the

timer duration period.

Timer End The timer end is an event, which is generated, when the timer arrives its conﬁgured

timer duration value.

The timer start and end event signals can be used to trigger other blocks, like counter, timer, acquisition, frame or exposure control.

5 Counter & Timer

5.2.4 Timer Reset

The timer can be reset by a software command. It performs a software reset of the timer counter and starts the timer immediately (change to state timer active), when trigger source is set to off; otherwise it goes into the state timer trigger wait.

5.2.5 Timer Trigger Source

The timer trigger source selects the events that will be the used to reset and to start the timer. The following list of signals are available:

Off Disables the timer trigger.

Acquisition Trigger Starts with the reception of the acquisition trigger event.

Acquisition Start Starts with the reception of the acquisition start event.

Acquisition End Starts with the reception of the acquisition end event.

FrameTrigger Starts with the reception of the frame trigger event.

Frame Start Starts with the reception of the frame start event.

Frame End Starts with the reception of the frame end event.

Frame Burst Start Starts with the reception of the frame burst start event.

Frame Burst End Starts with the reception of the frame burst end event.

Exposure Start Starts with the reception of the exposure start event.

Exposure End Starts with the reception of the exposure end event.

User Output 0 ... 7 Starts when the selected user output bit is set to 1.

Counter 0 ... 3 Start Starts with the reception of the chosen counter start event.

Counter 0 ... 3 End Starts with the reception of the chosen counter end event.

Timer 0 ... 3 Start Starts with the reception of the chosen timer start event.

Timer 0 ... 3 End Starts with the reception of the chosen timer end event.

Action 0 ... 3 Starts with the reception of the chosen action signal event.

Software Signal Pulse 0 ... 7 Starts with the reception of chosen software signal pulse event

(see Section 4.7).

Line Input Starts when the speciﬁed counter trigger activation condition is met on the chosen

line.

Line input source has additionally a activation conﬁguration, which needs to be set accordingly. Following conﬁguration values are available:

Rising Edge Timer starts with the rising edge on the selected line input.

Falling Edge Timer starts with the falling edge on the selected line input.

Both Edges Timer starts with any edge on the selected line input.

A self re-trigger timer can be conﬁgured, when the trigger source is set to its own timer end event. The timer needs a software reset in order to start the self re-trigger mode.

I/O Control

This chapter shows the structure of the physical input and physical output line. It describes the signal path and how to conﬁgure it.

The I/O control block contains a signal input path and a signal output path.

6.1 Input Signal Path

The camera has one physical signal input line, which comes from the input opto-isolator of the camera hardware interface (see Section 13.6) and which is fed into the input signal path of the camera. Fig. 6.1 shows the structure of the input signal path. The user can invert this signal and its current status can be read by software.

Figure 6.1: Input Signal Path

The output of the signal input path is distributed to following camera function:

• Acquisition Start Trigger

• Acquisition End Trigger

• Frame Start Trigger

• Frame Burst Start Trigger

• Frame Burst End Trigger

• Exposure Start Trigger

• Exposure End Trigger

• Counter Trigger

• Counter Event

• Counter Reset

• Timer Trigger

• Line Out

• LED S0, S1 or S2

6.2 Output Signal Path

The camera has one physical signal output line and three LEDs (S0, S1 & S2), which can be conﬁgured according to the need of the application. The physical output line is connected to the output opto-isolator in the camera hardware interface (see Section 13.6). The output line, LED0, LED1 and LED2 have its own output signal path which is shown in Fig. 6.2. The source can be selected and the selected signal can be inverted before it is sent out of the camera. Furthermore the current status of the output signal can read by software. Following signals are available and can be selected for the output:

If the source heartbeat is selected, the led shows a pulsating behaviour, when the camera is idle (no image capturing is active). It means, the intensity starts from dark and goes slowly to bright and slowly to dark again. Every time, when the camera is acquiring and sending images, the LED changes to a blinking characteristic.

If the source serial communication is selected, the led ﬂashes every time when the host communicates with the camera, due to changing or reading of camera parameters.

Action Control

Figure 7.1: Action Control Structure

Action signals are a method to send triggers to multiple cameras in a common network at the same time. Four action signals are available in the Photonfocus GigE cameras. Each of them can be used as a trigger for the image acquisition, counter and/or timer. The commands are sent via the transport layer as a broadcast protocol message. The conﬁguration parameters ActionDeviceKey, ActionGroupKey and ActionGroupMask in the camera allow ﬁltering of these broadcast messages: The corresponding action signal is only asserted, when the received broadcast message matches to its key and mask conﬁguration.

The action command enables triggering of the camera with low latency and low jitter.

7.1 Action Command Usage

Each action command message comes with the following key and mask information, which is necessary to validate the requested action signal:

ActionUnconditionalMode Enables the unconditional action command mode where action

ActionDeviceKey The ActionDeviceKey authorize the action in the camera. The camera reacts

ActionGroupKey The ActionGroupKey deﬁnes a group of devices on which the action has to be

The corresponding action signal is only asserted if:

• the conﬁgured ActionDeviceKey is equal to the action device key in the message.

• the conﬁgured ActionGroupKey is equal to the action group key in the message.

• the logical AND-wise operation of the action group mask in the message against the

7.2 Action Control Output

The action output signals can be used to trigger other blocks, like counter, timer, acquisition, frame or exposure control.

Image Format Control

The focus on the interesting parts of an image can be set by setting the region of interest (ROI) (see Section 8.1).

The ROI inﬂuences the image size which leads into an increased frame rate (see Chapter 9 for more information about the available frame rate).

8.1 Region of Interest (ROI)

Some applications do not need full image resolution. The image size can be reduced by setting the horizontal image offset (Offset X) and the image width (Width) and by setting the vertical image offset (OffsetY) and image height (Height). A region of interest can be almost any rectangular window but it must be placed within the sensor area. OffsetX + Width must not exceed the sensor width and OffsetY + Height must not exceed sensor height.

The ROI OffsetX and Width must be a multiple of 8 in the D2048x1088-C01 and the D2048-C01 cameras.

52 of 111 MAN078 12/2018 V1.1

Frame Rate

The frame rate depends on the image size, the used exposure time and the max data rate of the GigE interface (MaxDataRateInterface). The image size is given by the image size, which can be conﬁgured by the ROI, MROI and decimation settings (see Chapter 8).

Two different timing situations has to be considered:

• Exposure time is dominant

• Image size is dominant

Depending on the timing situation the frame rate is calculated according to the formula in Section 9.1 or in Section 9.2. In order to ﬁnd out what is dominant, both timing situation needs to be calculated and the lower value deﬁnes the maximum frame rate.

9.1 Exposure time is dominant

The frame rate is given by the conﬁgured exposure time. The maximal frame rate is in this case:

FrameRate = (1 / (ExposureTime + FramePause))

FramePause is 40...85 µs

9.2 Image size is dominant

The fame rate is given by the conﬁgured image size. The maximal frame rate is in this case is given by the max data rate of the GigE interface:

FrameRate = MaxDataRateInterface / (WidthMax x HeightMax x [Bits per Pixel])

Bits per pixel depends on the PixelFormat settings:

Mono8 8 bit per pixel

Mono10 16 bit per pixel

Mono10Packed 12 bit per pixel

Mono12 16 bit per pixel

Mono10Packed 12 bit per pixel

9.3 Maximum Frame Rate

A list of common used image dimension and its frame rates is shown in Table 9.1. It shows the maximum possible frame rates when the exposure time is smaller than the read out time.

There is a frame rate calculator in the support section of the Photonfocus web page www.photonfocus.com, which allows to determine the frame rates for any available image dimensions and expsoure time settings.

High Dynamic Range Mode (HDR)

10.1 Multiple Slope Mode (High Dynamic Range)

The Multiple Slope High Dynamic Range (HDR) mode is a special integration mode that increases the dynamic range of the pixels, and thus avoids the saturation of the pixels in many cases. The multiple slope mode is also called multiple slope mode or piecewise linear mode.

The multiple slope mode clips illuminated pixels which reach a programmable voltage, while leaving the darker pixels untouched (see Fig. 10.1). The clipping level can be adjusted once (2 slopes) or twice (3 slopes) within the exposure time.

Parameters:

Multislope_Mode There are 3 predeﬁned multiple slope parameter sets: LowCompression,

NormalCompression and HighCompression. If Multislope_Mode is set to UserDeﬁned then the

individual parameters can be set to user deﬁned values.

Multislope_NrSlopes Number of slopes. Multislope_NrSlopes=2: 2 slopes with only kneepoint B.

Multislope_NrSlopes=3: 3 slopes with kneepoints A and B.

Multislope_Value1 Corresponds to Vlow1: the higher the value, the higher the compression.

Multislope_Time1 Time corresponding to kneepoint B. The value is the fraction (per mill) of

the total exposure time.

Multislope_Value2 Corresponds to Vlow2: the higher the value, the higher the compression.

This value is ignored if Multislope_NrSlopes =2.

Multislope_Time2 Time corresponding to kneepoint A. The value is the fraction (per mill) of

the total exposure time. This value is ignored if Multislope_NrSlopes =2.

The red line in Fig. 10.1 shows a pixel with high illumination. Without the multiple slope mode, the pixel would have reached its saturated value. With multiple slope mode, the pixel reaches value P1 which is below the saturation value. The resulting pixel response in this case is shown in Fig. 10.2. The blue line (P2) shows a pixel with low illumination. Its value never reaches Vlow2 or Vlow1 at the kneepoints and the resulting response is linear.

The parameters Multislope_Value1 and Multislope_Value2 are only applied after a camera trigger. Note that in free-running mode the camera trigger is applied internally by the camera itself.

11.2 Column FPN Correction

Due to the readout structure of the image sensors there is a column-wise ﬁxed pattern noise (FPN). The Column FPN Correction (ColCorrection) adds or subtracts a ﬁxed value to a column. These values are obtained by a calibration process. The ColCorrection of the camera was calibrated at Photonfocus production facility.

11.2.1 Enable / Disable the Column FPN Correction

The Column FPN Correction can be enabled or disabled with the property ColCorrection_Enable (in category Photonfocus/ColCorrection). By default the correction is enabled.

11.2.2 Calibration of the Column FPN Correction

The Column FPN Correction of the camera is correctly calibrated at Photonfocus production facility. Although a new calibration is normally not required, you can recalibrate the Column FPN Correction with the following instructions:

1. Setup the camera to the mode where it will be usually used. (Exposure time, ...). The width and height should be set to its maximal value.

If different exposure times will be used, calibrate the camera under the longest exposure time.

2. Start the aqcuisition of the camera.

3. Close the lens of the camera or put a cap on the lens. The calibration requires an uniform dark image. The black level offset should be set so that all pixels (except defect pixels) have values above 0.

4. Run the command ColCorrection_CalibrateBlack (category ColCorrection) by clicking on the corresponding button.

The calibration process needs some images in order to do the calibration. If the camera is in triggered mode, the user must apply the corresponding triggers.

To get the best calibration results, the camera should have achieved the working temperatur.

5. Run the command ColCorrection_Update by clicking on the corresponding button. Read the ColCorrection_Busy value which should be 0 after the calibration has ﬁnished. Repeat this step if its value is not 0. If the ColCorrection_Busy value doesn’t show 0 after various tries, check if the camera receive triggers, when the triggered mode is activated.

6. Check the values of the properties ColCorrection_Overﬂow and ColCorrection_Underﬂow. Both should have the value 0 after calibration. If ColCorrection_Overﬂow is not 0, then decrease

BlackLevel (in category AnalogControl) and re-run the procedure from step 4 on. If ColCorrection_Underﬂow is not 0, then increase BlackLevel (in category AnalogControl) and

re-run the procedure from step 4 on.

7. The Column FPN correction is now calibrated. The calibration values are stored in the camera’s RAM and these values are lost when the camera power is turned off. To store the calibration values to permanent memory see Section 11.2.3.

MAN078 12/2018 V1.1 59 of 111

11 Image Data Processing

Column noise changes with different analog gain settings. The column FPN correction of the camera needs to be recalibrated when the analog gain setting is changed.

11.2.3 Storing the calibration in permanent memory

After running the calibration procedure (see Section 11.2.2) the calibration values are stored in RAM. When the camera is turned off, their values are lost.

To prevent this, the calibration values must be stored in ﬂash memory. This can be done by clicking on the property ColCorrection_SaveToFlash (in category ColCorrection). Wait until the command has been ﬁnished, i.e.the property ColCorrection_Busy (category Correction /

ColCorrection) is 0. ColCorrection_Busy can be updated by clicking on the property ColCorrection_Update (in category Calibration).

Storing the calibration in permanent memory overwrites the factory calibration.

11.3 Gain and Offset

There are three different gain settings on the camera:

Analog Gain Analog gain on the image sensor. Available values: x1, x1.6, x2.0, x2.6, x3.2 and

x4.0. Note that Digital Offset is applied after the Analog Gain.

Gain (Digital Fine Gain) Digital ﬁne gain accepts fractional values from 0.01 up to 15.99. It is

implemented as a multiplication operation. Colour camera models only: There is additionally a gain for every RGB colour channel. The RGB channel gain is used to calibrate the white balance in an image, which has to be set according to the current lighting condition.

Digital Gain Digital Gain is a coarse gain with the settings x1, x2, x4 and x8. It is implemented

as a binary shift of the image data where ’0’ is shifted to the LSB’s of the gray values. E.g. for gain x2, the output value is shifted by 1 and bit 0 is set to ’0’.

The resulting gain is the product of the three gain values, which means that the image data is multiplied in the camera by this factor.

Digital Fine Gain and Digital Gain may result in missing codes in the output image data.

A user-deﬁned value can be subtracted from the gray value in the digital offset block. If digital gain is applied and if the brightness of the image is too big then the interesting part of the output image might be saturated. By subtracting an offset from the input of the gain block it is possible to avoid the saturation.

11.4 Grey Level Transformation (LUT)

y = f ( x )

m a x

11.4 Grey Level Transformation (LUT)

Grey level transformation is remapping of the grey level values of an input image to new values. The look-up table (LUT) is used to convert the greyscale value of each pixel in an image into another grey value. It is typically used to implement a transfer curve for contrast expansion. The camera performs a 12-to-8-bit mapping, so that 4096 input grey levels can be mapped to 256 output grey levels. The use of the three available modes is explained in the next sections. Two LUT and a Region-LUT feature are available in the camera (see Section 11.4.4).

The LUT is implemented as a 12-to-8 bit LUT to be compatible with other Photonfocus cameras. Bits 0 & 1 of the 12 bit LUT input data are set to random values.

The output grey level resolution of the look-up table (independent of gain, gamma or user-deﬁnded mode) is always 8 bit.

There are 2 predeﬁned functions, which generate a look-up table and transfer it to the camera. For other transfer functions the user can deﬁne his own LUT ﬁle.

Some commonly used transfer curves are shown in Fig. 11.2. Line a denotes a negative or inverse transformation, line b enhances the image contrast between grey values x0 and x1. Line c shows brightness thresholding and the result is an image with only black and white grey levels. and line d applies a gamma correction (see also Section 11.4.2).

Figure 11.2: Commonly used LUT transfer curves

11.4.1 Gain

The ’Gain’ mode performs a digital, linear ampliﬁcation with clamping (see Fig. 11.3). It is conﬁgurable in the range from 1.0 to 4.0 (e.g. 1.234).

11.4.2 Gamma

The ’Gamma’ mode performs an exponential ampliﬁcation, conﬁgurable in the range from 0.4 to 4.0. Gamma > 1.0 results in an attenuation of the image (see Fig. 11.4), gamma < 1.0 results in an ampliﬁcation (see Fig. 11.5). Gamma correction is often used for tone mapping and better display of results on monitor screens.

11.5 Crosshairs

The crosshairs inserts a vertical and horizontal line into the image. The width of these lines is one pixel. The grey level is deﬁned by a 12 bit value (0 means black, 4095 means white). This allows to set any grey level to get the maximum contrast depending on the acquired image. The x/y position and the grey level can be set via the camera software. Figure Fig. 11.10 shows two examples of the activated crosshairs with different grey values. One with white lines and the other with black lines.

The 12-bit format of the grey level was chosen to be compatible with other Photonfocus cameras.

11.6 Status Line and Image Information

There are camera properties available that give information about the acquired images, such as integration time, ROI settings or average image value. These properties can be queried by software. Alternatively, a status line within the image data can be switched on that contains all the available image information.

11.6.1 Image Average Value

The average image value gives the average of an image in 12 bit format (0 .. 4095 DN), regardless of the currently used grey level resolution. Note that the 12-bit format was chosen to be compatible with other Photonfocus cameras

11.6.2 Status Line Format

If enabled, the status line replaces the last row of the image with camera status information. Every parameter is coded into ﬁelds of 4 pixels (LSB ﬁrst) and uses the lower 8 bits of the pixel value, so that the total size of a parameter ﬁeld is 32 bit (see Fig. 11.12). The assignment of the parameters to the ﬁelds is listed in Table 11.2.

The status line is available in all camera modes.

11 Image Data Processing

11.7 Test Images

Test images are generated in the camera FPGA, independent of the image sensor. They can be used to check the transmission path from the camera to the acquisition software. Independent from the conﬁgured grey level resolution, every possible grey level appears the same number of times in a test image. Therefore, the histogram of the received image must be ﬂat.

A test image is a useful tool to ﬁnd data transmission errors or errors in the access of the image buffers by the acquisition software.

The analysis of the test images with a histogram tool gives gives a ﬂat histogram only if the image width is a multiple of 1024 (in 10 bit mode) or 256 (in 8 bit mode).

11.7.1 Ramp

Depending on the conﬁgured grey level resolution, the ramp test image outputs a constant pattern with increasing grey level from the left to the right side (see Fig. 11.13).

Figure 11.13: Ramp test images: 8 bit output (left), 10 bit output (right)

11.7.2 LFSR

The LFSR (Linear Feedback Shift Register) test image outputs a constant pattern with a pseudo-random grey level sequence containing every possible grey level that is repeated for every row. The LFSR test pattern was chosen because it leads to a very high data toggling rate, which stresses the interface electronic and the cable connection. In the histogram you can see that the number of pixels of all grey values are the same.

Please refer to application note [AN026] for the calculation and the values of the LFSR test image.

11.7.3 Troubleshooting using the LFSR

To control the quality of your complete imaging system enable the LFSR mode, set the camera window to 1024 x 1024 pixels (x=0 and y=0) and check the histogram. The camera window can also be set to a multiple of this resolution (e.g. 2048 x 2048 or 4096 x 3072) if the camera model supports this resolution. If your image acquisition application does not provide a real-time histogram, store the image and use an image viewing tool (e.g. ImageJ) to display the histogram.

11.7 Test Images

Figure 11.14: LFSR (linear feedback shift register) test image

In the LFSR (linear feedback shift register) mode the camera generates a constant pseudo-random test pattern containing all grey levels. If the data transmission is correctly received, the histogram of the image will be ﬂat (Fig. 11.15). On the other hand, a non-ﬂat histogram (Fig. 11.16) indicates problems, that may be caused either by a defective camera, by problems in the acquisition software or in the transmission path.

Figure 11.15: LFSR test pattern received and typical histogram for error-free data transmission

In robots applications, the stress that is applied to the camera cable is especially high due to the fast movement of the robot arm. For such applications, special drag chain capable cables are available. Please contact the Photonfocus Support for consulting expertise.

Mechanical Considerations

14.1 Mechanical Interface

During storage and transport, the camera should be protected against vibration, shock, moisture and dust. The original packaging protects the camera adequately from vibration and shock during storage and transport. Please either retain this packaging for possible later use or dispose of it according to local regulations.

14.1.1 Cameras with GigE Interface

Fig. 14.1 shows the mechanical drawing of the camera housing for the Photonfocus MV0 GigE camera series.

Figure 14.1: Mechanical dimensions of the Photonfocus MV0 CMOSIS GigE cameras

For long life and high accuracy operation, we highly recommend to mount the camera thermally coupled, so that the mounting acts as a heat sink. To verify proper mounting, camera temperature can be monitored using the GeniCam command DeviceTemperature under GEVDeviceControl.

MAN078 12/2018 V1.1 85 of 111

14 Mechanical Considerations

14.2 Optical Interface

14.2.1 Cleaning the Sensor

The sensor is part of the optical path and should be handled like other optical components: with extreme care.

Dust can obscure pixels, producing dark patches in the images captured. Dust is most visible when the illumination is collimated. Dark patches caused by dust or dirt shift position as the angle of illumination changes. Dust is normally not visible when the sensor is positioned at the exit port of an integrating sphere, where the illumination is diffuse.

1. The camera should only be cleaned in ESD-safe areas by ESD-trained personnel using wrist straps. Ideally, the sensor should be cleaned in a clean environment. Otherwise, in dusty environments, the sensor will immediately become dirty again after cleaning.

2. Use a high quality, low pressure air duster (e.g. Electrolube EAD400D, pure compressed inert gas, www.electrolube.com) to blow off loose particles. This step alone is usually sufﬁcient to clean the sensor of the most common contaminants.

Workshop air supply is not appropriate and may cause permanent damage to the sensor.

3. If further cleaning is required, use a suitable lens wiper or Q-Tip moistened with an appropriate cleaning ﬂuid to wipe the sensor surface as described below. Examples of suitable lens cleaning materials are given in Table 14.1. Cleaning materials must be ESD-safe, lint-free and free from particles that may scratch the sensor surface.

Do not use ordinary cotton buds. These do not fulﬁl the above requirements and permanent damage to the sensor may result.

4. Wipe the sensor carefully and slowly. First remove coarse particles and dirt from the sensor using Q-Tips soaked in 2-propanol, applying as little pressure as possible. Using a method similar to that used for cleaning optical surfaces, clean the sensor by starting at any corner of the sensor and working towards the opposite corner. Finally, repeat the procedure with methanol to remove streaks. It is imperative that no pressure be applied to the surface of the sensor or to the black globe-top material (if present) surrounding the optically active surface during the cleaning process.

Troubleshooting

15.1 No images can be acquired

If no images can be acquired then the cause could be one of the following:

1. Camera is not triggered: see Section 15.1.1

First proceed with the above list in numerical order. If still no images can be acquired go back to step 2. If the problem persists then write an e-mail to Photonfocus support (support@photonfocus.com).

15.1.1 No acquisition due to no triggers

Set the camera to the free-running trigger mode (see Section C.1.1).

If no images can be acquired in free-running mode then triggering is not the main cause of the acquisition problem.

If images can be acquired in free-running mode but not in your chosen trigger mode then check the trigger conﬁguration (see Section C.1.3 and Section C.1.4), or the electrical connection of the trigger signal (see also Section 13.6).
