JAI GigE® Vision Camera operation manuals

To understand and operate this JAI GigE® Vision camera properly, JAI provides the following manuals.

User’s manual (this booklet) Describes functions and operation of the hardware JAI SDK & Control Tool User Guide Describes functions and operation of the Control Tool JAI SDK Getting Started Guide Describes the network interface

User’s manual is available at www.jai.com JAI SDK & Control Tool User Guide and JAI SDK Getting Started Guide are provided with the JAI SDK which is available at www.jai.com.

Introduction

GigE Vision is the new standard interface using Gigabit Ethernet for machine vision applications and it was mainly set up by AIA (Automated Imaging Association) members. GigE Vision is capable of transmitting large amounts of uncompressed image data through an inexpensive general purpose LAN cable for a long distance.

GigE Vision also supports the GenICamTM standard which is mainly set up by the EMVA (European Machine Vision Association). The purpose of the GenICam standard is to provide a common program interface for various machine vision cameras. By using GenICam, cameras from different manufactures can seamlessly connect in one platform.

For details about the GigE Vision standard, please visit the AIA web site,

www.machinevisiononline.org and for GenICam, the EMVA web site, www.genicam.org.

JAI GigE Vision cameras comply with both the GigE Vision standard and the GenICam standard.

Camera Operation

1. General

The AT-200GE complies with GenICam Standard Features Naming Conversion (SFNC) ver.1.3 and functions described in this booklet are described based on this standard. The AT-200GE is a digital 3CCD progressive scan RGB color camera. It employs three 1/1.8inch 1624 (h) x 1236 (v), 2 Megapixel CCDs and runs at 15.45 frames per second in full resolution mode. The AT-200GE has a GigE Vision interface and its output can be either 24-bit or 32-bit RGB. JAI developed a new 1/1.8-inch compact F4.0 prism optical system and in combination with a linear color matrix, the AT-200GE provides a higher fidelity of color reproduction. The AT-200GE also incorporates a dynamic shading circuit, gamma correction circuit and knee correction circuit to provide high picture quality. Functions like AOI and vertical binning allow higher frame rates.

6.3. Iris video output

This signal can be used for lens iris control In self running mode. The signal is NUM luminance signal and passes through the gain circuit. However, due to reversed compensation applied, the gain settings do not influence this signal. The iris video output is 0.7 V p-p from 75  and without sync.

Fig. 13 Iris video output.

6.4. Trigger input

The trigger input is on Opt in pins #4 or #6 on the 12-pin connector(see section 6.2 for voltages and schematic) or pin#3 on the Dsub 9-pin connector. As shown in the diagram to the right, the input on the 9-pin connector is AC coupled. To allow a long pulse width, the input circuit is a flip-flop, which is toggled by the negative or positive differentiated spikes caused by the falling or rising trigger edges. The trigger polarity can be changed. Trigger input level is 4 V 2 V. It can be terminated by SW600: ON for 75. OFF for TTL(Factory default). Fig.14 9-pin trigger input.

6.5. Exposure Active output

Exposure Active signal (positive) is found on Opt-out on Hirose 12P (see section 6.2) or TTL out on D-sub 9-pin connector. The output circuit on the 9-pin (right) is 75  complementary emitter followers. Output level 3 V from 75. (No termination). It can be changed to the open collector signal. When the open collector is used, the maximum current is 1/1.80mA. However, if a current of more than 50mA is flowed, it is necessary to use bigger diameter wires for connecting pin#8 and 9. In case of narrower wires, due to its resistance, it may not work properly. This output can be changed to Open collector signal by SW100. Fig.15 ExposureActive TTL output

7.8. The calculation of AOI size and frame rate

The frame rate in the AOI setting is calculated by the following formula.

Frame rate (fps) = Horizontal frequency(19.27KHz) / Total lines

Total lines =  OB period +  Transition period before start line(L) +

 Effective image period (L) +  Transition period after end line(L) +  Blank period (L)

Where,

OB period = 4L (Fixed)

Blank period =5L (Fixed)

Transition period after end line = (1236-927+2) ÷ 9 =34.6  35 Total lines = 4+36+618+35 +5 = 698 Frame rate = 19.27/ 698 =27.6 fps

7.9. The relationship between LinePitch and Width

The setting range of LinePitch is changed when the output is set at 8-bit or 10-bit. LinePitch can be set as follows.

RGB8Packed ：24-4920 REB10V1Packed：32-6560 REB10V2Packed：32-6560

Note: The unit is byte.

If the minimum is 8 pixels and the output is RGB 8bit, 8 pixels x 3Byte =24Byte If the maximum is 1640 pixels and the output is RGB 8bit, 1640 pixels x 3Byte = 4224Byte.

As for LinePitch and Width, if one is changed, the other will also be changed. The relationship between LinPitch and width is;

RGB8Packed ：Linepitch/3 REB10V1Packed：Linepitch/4 REB10V2Packed：Linepitch/4

As the width is change, the output area will also be changed.

7.10. The relationship between PxelSIze and PixelFormat

PixelSize and PixelFormat are interlocked for each setting. If PixelSize is Bpp24, PixelFormat is RGB8Packed If PixelSize is Bpp32, PixelFormat is RGB10V18Packed or RGB10V2Packed

This relationship works reversely too.

7.11. The relationship between Binning Horizontal and Width/LinePitch

If Binning Horizontal is set at 1(OFF) or 2(ON), Width/LinePitch is changed accordingly. Binning Horizontal = 1 Width is 1640 as the maximum Binning Horizontal = 2 Width is 820 as the maximum

Note: If Binning Horizontal is reset to 1 after setting to 2, the maximum value is not

changed. It is necessary to reset manually.

7.12. The relationship between Binning Vertical and Height

If Binning Vertical is set at 1(OFF) or 2(ON), Height is changed accordingly. Binning Vertical = 1 Height is 1240 as the maximum Binning Vertical = 2 Height is 622 as the maximum

Note: If Binning Vertical is reset to 1 after setting to 2, the maximum value is not

changed. It is necessary to reset manually.

8. Network configuration

 For details of the network settings, please refer to the “Getting Started

Guide” supplied with the JAI SDK.

8.1. GigEVision Standard interface

The AT 20- 0GE is designed in accordance with the GigE Vision standard. Digital images are transmitted over Cat5e or Cat6 Ethernet cables. All camera functions are also controlled via the GigE Vision interface.

The camera can operate in Continuous mode, providing an endless stream of images. For capturing individual images related to a specific event, the camera can also be triggered. For precise triggering, it is recommended to use a hardware trigger applied to the Hirose 12-pin connector. It is also possible to initiate a software trigger through the GigE Vision interface. However, when using a software trigger, certain latency inherent to the GigE interface must be expected. This latency, which manifests itself as jitter, greatly depends on the general conditions and traffic on the GigE connection. The frame rate described in this manual is for the ideal case and may deteriorate depending on conditions.

When using multiple cameras (going through a switch and/or a single path) or when operating in a system with limited transmission bandwidth the Delayed Readout Mode and Inter-Packet Delay functions can be useful.

8.2. Equipment to configure the network system

8.2.1 PC

The PC used should have the following performance or better

1) Recommended CPU : Core2 Duo 2.4GHz or better, Better than Core2 Extream

2) Recommended memory : 2Gbyte or more

3) Video card : Better than PCI Express Bus Ver.1.0 x16

VRAM should be better than 256MByte, DDR2

4) Other : The resident software should not be used

8.2.2 Cables

GigEVision configures the system by using 1000BASE-T. (100BASE-T can be used with some restriction. Refer to chapter 8.3.5). In the market, CAT5e (125MHz), CAT6 (250MHz) and CAT7 (600MHz) cables are available for 1000BASE-T. There are crossover cables and straight through cables available. Currently, as most equipment complies with Auto MDI/MDI-X, please use straight through cables. (Among crossover cables, a half crossover type exists, which the Ethernet will recognize as 100BASE-T).

8.2.3 Network card (NIC)

The network card should comply with 1000BASE-T and also have the capability of JUMBO FRAMES. When the jumbo frame size is set at a larger number, the load on the CPU will be decreased. Additionally, as the overhead of the packet is decreased, the

transmission will have more redundancy.

JAI confirms the following network cards.

8.2.4 Hub

It is recommended to use the metal chassis type due to the shielding performance. As the hub has a delay in transmission, please note the latency of the unit.

8.3. Recommended Network Configurations

Although the AT-200GE conforms to Gigabit Ethernet (IEEE 802.3) not all combinations of network interface cards (NICs) and switches/routers are suitable for use with the GigE Vision compliant camera. JAI will endeavor to continuously verify these combinations, in order to give users the widest choice of GigE components for their system design.

 For details of the network settings, please refer to the “Getting Started

Guide” supplied with the JAI SDK.

8.3.1 Guideline for network settings

To ensure the integrity of packets transmitted from the camera, it is recommended to follow these simple guidelines:

1. Whenever possible use a peer-to-peer network.

2. When connecting several cameras going through a network switch, make sure it is

capable of handling jumbo packets and that it has sufficient memory capacity.

3. Configure inter-packet delay to avoid congestion in network switches.

4. Disable screen saver and power save functions on computers.

5. Use high performance computers with multi-CPU, hyper-thread and 64-bit CPU,

etc.

6. Only use Gigabit Ethernet equipment and components together with the camera.

7. Use at least Cat5e and preferably Cat6 Ethernet cables.

8. Whenever possible, limit the camera output to 8-bit.

Note1: Depending on the packet size, the frame rate of 15.45 fps may not be achieved. This figure will depend of the system configuration used (RESEND not possible)

 If Jumbo Frames (Max.16020) are not used, the packet data will be bigger by 2%.  If Jumbo frames are used, the packet size may be automatically optimized to a

smaller size.

 For details of setting Jumbo Frames, please refer to the “Getting Started

Guide”.

8.3.3 Note for setting packet size

The packet size is set to 1428 as the factory default. Users may enter any value for the packet size and the value will be internally adjusted to an appropriate, legal value that complies with the GenICam standard. The packet size can be modified in the GigE Vision Transport Layer Control section of the camera control tool.

Regarding data transfer rate, a larger packet size produces a slightly lower data transfer rate. The AT-140GE can support a maximum of 16020 byte packets provided the NIC being used has a Jumbo Frames function with a setting of a 16020 bytes or larger.

Caution: Do not set the packet size larger than the maximum setting available in

the NIC or switch to which the camera is connected . Doing so will cause output to be blocked.

8.3.5 Simplified calculation (Approximate value)

A simple way to calculate the approximate data transfer rate is the following.

Transfer data = image width (pixel) x Image Height (pixel) x depth per pixel(depending

on the pixel format) x frame rate / 1,000,000 (convert to mega bit)

In the case of the AT-200GE with the full image and RGB 8bit pixel format; The data transfer rate = 1624 x 1236 x 24 x 15.45 / 1000000 = 744 Mbit/s

8.3.6 Note for 100BASE-TX connection

 In order to use 100Mbps network, 100BASE-TX and Full Duplex are available. Half

Duplex cannot be used.

 In the case of connecting on 100BASE-TX, the maximum packet size should be 1500

bytes.

 In the case of connecting on 100BASE-TX, the specifications such as frame rate,

trigger interval and so on described in this manual cannot be satisfied.

8.4. GigE camera connecting examples

8.4.1 Using a switching hub for 1 port

 All cameras and NIC belong to the same subnet  The accumulated transfer rate for all cameras should be within 800Mbps  The packet size and the packet delay should be set appropriately in order

for the data not to overflow in the switching hub.

8.4.2 Connecting a camera to each port of a multi-port NIC

 This is the example for using a 4-port NIC  The pair of the connecting camera and the NIC constructs one subnet. As for

the IP configuration, it is appropriate to use the persistent IP.

 In this case, each camera can use the maximum 800Mbps band width.

However, the load for the internal bus, CPU and the application software become heavy, so a powerful PC will most likely be required.

8.4.3 The data transfer for multiple cameras

8.4.3.1 If delayed readout is not used in continuous mode

 The packet delay should be set larger. The data traffic is controlled by the

buffer of the hub. It is necessary to check the buffer value of the unit.

8.4.3.2 If delayed readout is not used in trigger mode

 The packet delay should be set larger. The data traffic is controlled by the

buffer of the hub. It is necessary to check the buffer value of the unit.

9. Core functions

 The function naming of the AT-200GE complies with GenICam SFNC ver.1.3.

Most of the camera’s core operation is controlled by a combination of standard GenICam

features related to acquisition, triggering, and exposure. Additional control is provided via built-in counter, timer, and event functions.

9.1. Acquisition function

Before using trigger and exposure controls, various acquisition controls must be set. The operation of the camera depends on the interrelationship of all three feature sets.

Fig.27 Acquisition control, Trigger/Exposure control work flow

9.1.1 Basic image acquisition flow The basic commands for acquiring images are as follows:

Acquisition mode To determine the number of the frame to be captured

The flow of these commands is shown below. The following drawings are based on the conditions that the Acquisition mode is Single and the Trigger selector is Frame Start.

If the acquisition start is set at ON (The acquisition is controlled externally)

If the acquisition start is set at OFF (The acquisition is controlled internally)

The following sections provide the details for each command set.

9.1.2 Acquisition mode

The AT-200GE has three settings for capturing images.  Single frame

AcquisitionStart command outputs one frame. Then the acquisition is

stopped.

 MultiFrame AcquisitionStart command outputs frames which are set by AcquisitionFrameCount. After the set frames are output, the acquisition is stopped.

 Continuous

AcquisitionStart command outputs frames until AcquisitionEnd is initiated.

9.1.2.1 Single Frame

In single frame mode, executing the AcquisitionStart command causes one frame to be captured. After one frame is captured, this operation is automatically stopped. In order to restart the capture, it is necessary to input the AcquisitionStart command again. BlockID is not reset until AcquisitionEnd is input and is incremented when the AcquisitionStart command is called.

◆ Normal single frame operation

1) AcquisitionStart command is input

2) AcquisitionActive becomes “TRUE” (accepts capture)

3) 1 frame is output

4) AcquisitionActive becomes “FALSE” (stop capturing)

◆ Forcing acquisition to stop

While AcquisitionActive is “TRUE”, if AcquisitionEnd or AcquisitionAbort is initiated, AcquisitionActive becomes “FALSE” (stop capturing).

Related functions: AcquisitionStart、AcquisitionStop、AcquisitionAbort

9.1.2.2 MultiFrame

In this mode, the AcquisitionStart command captures the number of frames which are specified by AcquisitionFrameCount. AcquisitionFrameCount can be set in the range of 1 to 255 frames. After all frames are captured , this operation is automatically stopped.

◆ Normal multi-frame operation

1) AcquisitionStart command is input

2) AcquisitionTriggerWait becomes effective

3) AcquisitionActive becomes “TRUE”

4) Output N frames as specified by AcquisitionFrameCount

5) AcquisitionActive becomes “FALSE”. Then the output stops. (See the following

Related functions: AcquisitionStart、AcquisitionFrameCount, AcquisitionEnd、

AcquisitionAbort

9.1.2.3 Continuous mode

In this mode, when the AcquisitionStart command is set, the image is continuously output at the current frame rate. This is the default setting for the AT-140GE.

1) AcquisitionStart command is input

2) AcquisitionTriggerWait becomes effective

3) AcquisitionActive becomes “TRUE”

4) Images begin outputting continuously

5) AcquisitionEnd command is sent

6) AcquisitionActive becomes “FALSE”. At this moment, the output stops.

9.1.3 AcquisitionAbort

AcquisitionAbort forces capture to stop if the AcquisitionAbort command is set while AcquisitionTriggerWait is effective or during exposure. The exact behaviour depends on the status of acquisition and readout:

Condition 1 - While reading out from CCD:

CCD readout and streaming continue. After they are completed, AcquisitionActive becomes “FALSE”(stop capturing).

At this moment, if AcquisitionStart is set, restart the capturing.

Condition 2 – Acquisition is active, but CCD readout is not yet initiated:

After the exposure is completed, the output is not initiated. AcquisitionActive becomes “FALSE”.

Condition 3 - Awaiting a trigger:

AcquisitionActive immediately becomes “FALSE”(capturing is not possible).

9.1.4 AcquisitionFrameCount

If Acquisition Mode is set to MultiFrame, AcquisitionFrameCount can set the number of frames to be captured each time the AcqusitionStart command is input. Setting range is 1 to 255 frames.

Fig.31 Acquisition Frame Count

9.1.5 AcquisitionFrameRate

1) In the trigger OFF mode (self running mode), it is possible to set the exposure period longer than the number of lines required for CCD drive in the designated area of interest (AOI).

2) The number of lines set by AcquisitionFrameRate determines the frame period.

3) The range of lines which can be set by AcquisitionFrameRate is 1 to 65535(16-bits).

The shortest period is dictated by the number of lines required for the desired

partial scan/AOI readout (see formula in section 7.8).

4) AcquisitionFrameRate cannot be used if the trigger mode is ON.

5) This function is useful for a long term exposure or time lapse output.

9.1.5.1 Setting the free running mode (Trigger OFF)

The free running mode can be utilized under one of the following conditions:

① ExposureMode is OFF ② ExposureMode is Timed and FrameStart is OFF and ExposureStart is OFF. ③ ExposureMode is TriggerWidth and FrameStart is OFF and ExposureStart is OFF. ④ ExposureMode is TriggerControlled and ExposureStart or ExposureEnd is OFF.

The following table shows the configurations for“free running”the camera. If the exposure mode is set Timed and the frame start and exposure start of the

trigger selector are set OFF, the exposure can be controlled.

The shortest frame period varies depending on the number of lines to be read out (e.g., partial scanning 618 image lines requires a total of 698 lines to be read out – see formula in section 7.8). If the line number setting is smaller than the number of lines required to support the AOI, the line number setting is ignored and the frame

period is based on the total number of OB, blanking, transition, and image lines. If all pixels are read out, the maximum frame rate is 19.27KHz which is 1248 total lines.

9.1.5.2 The calculation of the frame rate for the setting area

1. Binning Vertical=1 (OFF)

Line frequency ＝37125000Hz/1926clk=19276Hz Frame frequency＝19276Hz /total number of lines

Note: for the minimum 8-line partial scan, the total line number is 366.

2. Binning Vertical=2 (ON)

Line frequency ＝37125000Hz/2136clk=17381Hz Frame frequency ＝17381Hz / Setting total line number

Please refer to chapter 7.8 for the formula for line number calculation.

9.1.6 AcquisitionStatus

AcquisitionStatus can show the operating status of the following signals set by AcquisitionStatusSelector.

10. Operation modes

10.1. Continuous mode (Free run)

For applications not requiring asynchronous external triggering, this mode should be used. In this mode it is possible to use a lens with a video controlled iris. As for the timing, please refer to chapter 7.7 “Video output timing”. In continuous mode, exposure time can be controlled by the frame rate or by the electronic shutter. The following examples describe the GenICam settings used to configure the camera for continuous operation.

10.2. Trigger operation with “timed” exposure (Previously called EPS)

An external trigger pulse initiates the capture, and the exposure time (accumulation time) is set in advance. The minimum active period of the trigger is 66μsec and the minimum trigger interval is shown below.

Mode

Minimum trigger interval

Overlap is set at “Readout” and the trigger is input during the readout (LVAL Sync)

1248L + 3L

Overlap is set at “OFF” or “Readout” and the trigger is input during the readout is not activated. (LVAL Async)

Exposure time + 1248L + 3L

Note: 1) On the above table, 1248L is FVAL interval on normal continuous mode

2) If BinningVertical is effective, 1L is different from the normal scanning. So, the minimum trigger interval will be different.

Note: If the exposure time of R channel is 1/15sec. and the exposure time of G channel is

1/50,000sec., the image quality of the green channel at the 1/50,000 sec exposure time speed may not be guaranteed due to the fundamental CCD operation. In this mode, it is recommended to use the same exposure time for all three channels. If it is necessary to use with the different exposure time, please check the image quality first.

10.3. Trigger operation by “TriggerWidth” (Previously called PWC)

In this mode the accumulation time is equal to the trigger pulse width. Here it is possible to have a long time exposure. The minimum active period of the trigger is 2L and the minimum trigger interval is shown as follows.

10.5. Trigger input and exposure start timing

Triggeroverlap

This function is used to set whether the trigger can be accepted during the data readout in cases where FrameStart trigger or ExposureStart trigger are “ON”.

OFF: While the CCD reads out the data, the trigger cannot be accepted.

This works as LVAL asynchronous operation.

ReadOut: While the CCD reads out the data, the trigger can be accepted.

In this mode, if the trigger is input during CCD readout, it works as LVAL synchronous and if the trigger is input while the CCD is not reading out, it works as LVAL asynchronous.

This is the same behaviour as LVAL SYNC/ASYNC auto detection.

Note: During synchronous reset, a jitter of up to 1 LVAL will occur from trigger input

to exposure start and end. During asynchronous reset, there is no jitter.

The minimum trigger interval is shown as follows. The synchronous reset shows the shorter interval.

11. Image processing

11.1. Basic construction

The AT-200GE is a 3CCD camera equipped with F4, 1/1.8 inch prism optics. Red, green and blue color signals are taken from each 2 mega CCD which are filtered to the red, green and blue spectral wavelengths. A 32-bit microprocessor controls all functions in the AT-200GE camera. The CCD sensor output is normalized in CDS and preamplifiers. The signals are then digitized to 16 bits. Digital gain control, color matrix, look-up tables and setup can do signal processing in 16 bits before the signal is converted to a 30- or 24-bit RGB pixel format via GigE Vision interface.

Fig.47 Principle diagram for signal processing

11.2. Shading compensation

The AT-200GE implements a digital shading compensation circuit for the white shading which could be caused in the prism or optical system. The whole image is divided horizontally and vertically and uses the center level as the reference. The circuit will compensate the difference between the center and each divided area. The range for compensation is a maximum of 25%. In the factory, the shading compensation is activated and stored in the “Factory” area of the memory. The user can uses this data if the shading compensation is ON.The factory default is OFF. The AT-200GE has two shading compensation circuits.

1. Color shading compensation

In this mode, the shading is compensated using the G channel as the reference. Adjust R and B channels to match the characteristics of the G channel. Use white

balance to match R, G and B levels.

2. Flat shading compensation In this mode, each channel can be adjusted to achieve flat characteristics.

Fig.49 Conceptual drawing for flat shading compensation

Note: The maximum level of the shading compensation is 25%. In a certain

circumstances such as lighting conditions or used lenses, it may not be compensated. The following is the lens condition. Use 1/1.8 inch type and lens designed for 3CCD camera. The shading depends on the focal length and F number. The wide angle lenses or using a lens in fully open iris condition may deteriorate the shading characteristics.

In order to perform the shading compensation,

Shading correction mode: Select Flat shading or Color shading Shading Enable: True Shading selector: Select R, G or B In case of color shading, select R or B Shading correct: Perform Shading Calibration In order to store the data, select user I or 2 in User selector and activate User set

load.

11.3. Auto White balance

The AT-200GE has 2 auto white balance modes: one push auto white balance or continuous auto white balance. The white balance can adjust R channel and B channel using G channel as the reference in order to set three channels equal. The reference color temperature is 7500K.

The measuring area for the auto while balance is the same as the area of the output(AOI).

11.4. Gain

The analogue gain and the digital gain can be set from the external. Each functions are the following. Analog All: This is the master gain control. This can set R,G and B simultaneously.

The range is 0 to 15dB. Analog Red: R gain for WihteBalance and the range is ±6dB. Analog Blue: B gain for WihteBalance and the range is ±6dB. Digital All: This is for the fine tuning of the master gain. The range is ±3dB. Digital Red: This is for the fine tuning of R channel and the range is ±3dB. Digital Blue: This is for the fine tuning of B channel and the range is ±3dB.

Note: If WhiteBalace(Balance Ratio) is set, the level of Analog Red and Analog Blue is

applied.

11.4.1 GainAuto

This is the auto level control using Gain command. JAI AGC Reference can control the brightness of the auto gain. GainAuto select OFF, Once or Continuous. The adjusting range is:

JAI AGC Reference： 0 to 255 Gain ： 0 to 15dB（5.6 times）

11.5. BlackLevel

The black level of the image can be controlled by 1 LSB step for 10bit output.

11.6. Linear matrix

The AT-200GE incorporates a linear color matrix circuit to improve color reproduction. As this circuit processes signals in the linear stage, before the gamma correction circuit, the gamma circuit does not affect color reproduction. The linear matrix is set by “Color Transformation Selector”. This is “OFF” at the default setting.

This circuit has:

1. Linear : OFF

2. RGB to RGB : The individual setting for R,G or B is possible.

3. RGB to Custom 1 : sRGB setting. Standard which HP and Microsoft

specify for printers and monitors. This preset is based on this standard.

4. RGB to Custom 2 : Adobe RGB setting. Standard which Adobe systems specify. This preset is based on this standard.

Important Note:

If sRGB or Adobe RGB is used, please note the following procedure.

1) Achieve the white balance under the condition of D65 (6500K) illumination.

2) Gamma should be set at 0.45 and set the linear matrix at either sRGB or Adobe RGB.

3) Monitor should comply with sRGB or Adobe RGB color reproduction capability.

11.7. LUT (Look Up Table) and gamma

The AT-200GE uses LUT(Look UP Table) to adjust the gamma. JAI LUT mode is used for this function. If LUT is selected, the required gamma characteristics can be achieved. The gamma can be set from 1.0 to 0.45.

Fig.50 Gamma setting

Note: The analog signal is used only internally.

11.8. Test pattern generator

The AT-200GE has an internal test pattern generator. These signals are output as the last process of the digital signal processing circuit and can be used for adjustment of the related system. The AT-200GE has a total of 6 test pattern types.

12. Examples of operation using JAI Control Tool

Special attention: In this chapter, the images for AT-140GE are used for

explanation purpose.

12.1. About GenICamTM SFNC1.3

The AT-200GEis designed as conforming to GenICam SFNC1.3. GenICam SFNC stands for GenICam Standard Feature Naming Convention. By defining the standard cases and the standard features, general-purpose software can control cameras from any manufacturers which conform to the GenICam standard.

JAI, in the past, used traditional feature names in order to maintain naming continuity with previous cameras. However, starting with the AT-140GE and after, JAI GigE Vision cameras will now fully comply with GenICam SFNC feature names.

Accordingly, terminologies used for functions will be much different from previous models. This manual explains the basic operation using feature names specified in the GenICam SFNC 1.3 specification.

The latest version of JAI GigE Vision cameras comply with GenICam SFNC1.3. However, JAI can offer the following options for customers who use older versions of GIgE Vision cameras.

JAI provides the following software.

1. Version prior to SFNC 1.3 for older camera version

2. Downgrade to old version from the latest SFNC 1.3 version

Please contact local sales representatives for the details

12.2. JAI SDK Ver.1.3

JAI SDK has also been upgraded to version 1.3. In a GigE Vision compliant camera, all features are described in the XML file inside the camera and after connecting JAI Control Tool software, all features are downloaded to the JAI Control Tool software. If customers use older versions of cameras together with the Control Tool software ver.1.3, feature properties shown in the Control Tool exhibit old features name, enabling customers to operate cameras in a familiar way.

If the latest version of the camera is connected, some traditional JAI feature names such as JAI Preset Shutter, will display in the Feature Properties in addition to the newer GenICam SFNC 1.3 names.

These feaures can be set as usual and settings for those features are reflected automatically in the GenICam SFNC 1.3 feature names.

The features shown above will vary depending on the specific camera.

AT-200GE

12.3. Examples of camera operation

The following explains the operation of the camera using the GenICam SFNC 1.3 Control Tool.

12.3.1 Operational cautions

1. Features shaded gray in the Features Properties can not be set.

2. If the image size is to be changed, image capturing should first be stopped before setting the size parameters.

12.3.2 Connecting camera(s)

Connect the camera to the network. If the connection is established, start the JAI Control Tool. The model name of the connected camera and icon will be displayed in the screen.

After clicking the icon, the status will change to indicate the camera is successfully

connected to the Control Tool.

12.2.3 Camera setting layers

GenICam has 3 levels of settings. Those are Beginner, Expert and Guru. The number of available settings increase with each level up to a maximum in the Guru layer.

The following examples of Acquisition control menus illustrate how settings expand from level to level.

12.4. Input and output settings

12.4.1. Connection with the external devices

The relation of the line input and output (Digital I/O) and the external terminal in the JAI GigE Vision cameras is fixed. Refer to section 6.1 for the details.

In the Control Tool, they are displayed as Line1-TTL Out 1.

Note: These settings are only available in the Expert and Guru setting layers.

12.4.2. Setting inputs and outputs

12.4.2.1 Select signal to connect with Line which is selected by Line selector

This function determines which signal is connected with Digital I/O (Line 1 through

Line 8). The following figure is an example of setting Line 5 –Opt In 1. In this case, Line Source is the signal to connect with Line 5 -Opt In 1. But Frame Active is available for only output and accordingly, it is not selectable in the Control tool. Line Format is automatically set at Opto Coupled.

The following figure is an example of setting output so that the signal output from Line1 – TTL Out 1is selected from signals in the Line Source. In this case, Exposure Activeis selected to output through TTL Out 1. TTL is automatically selected as Line Format.

AT-200GE

12.4.2.2 Select Trigger Source

Which signal is used as the trigger signal can be configured by the Trigger Source in the Trigger Selector of Acquisition Control. In the following figure, Frame Start is selected as the trigger and the trigger source is configured Line7 – TTL In 1. In the following picture, Trigger Mode is OFF. But to activate the trigger, it should be set ON.

12.4.3. Specify the image size to be captured

Refer also to the chapter 7.2. The following parameters are required to specify the image size. OFFSET X Specify the starting position of the image in the horizontal

direction Width Specify the width of the image OFFSET y Specify the starting line of the image Height Specify the height of the image

AT-200GE

- 68 -

In order to readout full pixels,

OFFSET x = 0

Width = Maximum number of pixels in the horizontal direction

OFFSET y =4

Height= Maximum number of pixels in the vertical direction

In the AT-200GE, total pixels include pixels in the OB. In order to transfer the full pixel image without OB, a setting of OFFSET x = 0 and OFFSET y = 4 is the starting point. Refer to the chapter 7.2.2.

After setting the acquisition, click Start Acquisition button.

12.4.4.1 Basic settings

The basic setting items are Acquisition Mode, Trigger Selector, Exposure Mode.

Acquisition Mode

Acquisition Mode can be selected from Continuous, Single Frame and Multi Frame.

Continuous: If the trigger is input, the image is continuously captured.

In order to stop the acquisition, Acquisition End command must be executed.

Single Frame: If the trigger is input, only one frame is captured and after the

completion of capturing, the acquisition is automatically stopped.

AT-200GE

- 71 -

Trigger Selector includes Acquisition Start and Acquisition End commands which determine the start point and end point of acquisition, and Trigger commands which set the trigger timing.

Acquisition Start has ON or OFF setting. Refer to chapter XX for the details.

ON: In this case, if Acquisition Start Trigger is applied, the status is waiting the

trigger input. The acquisition starts in the order of Acquisition start Trigger input and Trigger signal input.

OFF: In this case, the camera runs freely. If the trigger signal is input, the

acquisition starts immediately.

Trigger setting

Select from Frame Start, Exposure Start, Exposure End and JAI Acquisition Transfer Start and set the details.

Frame Start: The exposure starts at the point of frame start. Exposure Start : The exposure starts at the point of exposure start. Exposure End : This command stops the exposure. This is used together with Exposure Start and Trigger Controlled. JAI Acquisition Transfer Start : This command makes the delayed readout from the

camera effective.

Exposure Mode setting

Timed : The exposure is effective only for setting duration. Trigger Width : The exposure time is equal to the trigger width. Trigger Controlled : Exposure Start Trigger starts the exposure and

Exposure End stops the exposure.

Appendix

1. Precautions

Personnel not trained in dealing with similar electronic devices should not service this camera. The camera contains components sensitive to electrostatic discharge. The handling of these devices should follow the requirements of electrostatic sensitive components. Do not attempt to disassemble this camera. Do not expose this camera to rain or moisture. Do not face this camera towards the sun, extreme bright light or light reflecting objects. When this camera is not in use, put the supplied lens cap on the lens mount. Handle this camera with the maximum care. Operate this camera only from the type of power source indicated on the camera. Power off the camera during any modification, such as changes of jumper and switch settings.

2. Typical Sensor Characteristics

The following effects may be observed on the video monitor screen. They do not indicate any fault of the camera, but are associated with typical sensor characteristics.

V. Aliasing

When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on the monitor may appear.

Blemishes

All cameras are shipped without visible image sensor blemishes. Over time some pixel defects can occur. This does not have a practical effect on the operation of the camera. These will show up as white spots (blemishes). Exposure to cosmic rays can cause blemishes to appear on the image sensor. Please take care to avoid exposure to cosmic rays during transportation and storage. It is recommended using sea shipment instead of air flight in order to limit the influence of cosmic rays on the camera. Pixel defects/blemishes also may emerge due to prolonged operation at elevated ambient temperature, due to high gain setting, or during long time exposure. It is therefore recommended to operate the camera within its specifications.

Patterned Noise

When the sensor captures a dark object at high temperature or is used for long time integration, fixed pattern noise may appear on the video monitor screen.

3. Caution when mounting a lens on the camera

When mounting a lens on the camera dust particles in the air may settle on the surface of the lens or the image sensor of the camera. It is therefore important to keep the protective caps on the lens and on the camera until the lens is mounted. Point the lens mount of the camera downward to prevent dust particles from landing on the optical surfaces of the camera. This work should be done in a dust free environment. Do not touch any of the optical surfaces of the camera or the lens.
