Table 3: Diagnostic LED

2.2.2 Power Connector

Figure 10: Hirose 6-pin Circular Male—Power Connector

The camera requires a single voltage input (+12 to +15VDC). The camera meets all performance specifications using standard switching power supplies, although wellregulated linear supplies provide optimum performance.

WARNING: When setting up the camera’s power supplies follow these guidelines:

 Apply the appropriate voltages  Protect the camera with a fast-blow fuse between power supply and camera.

 Do not use the shield on a multi-conductor cable for ground.  Keep leads as short as possible to reduce voltage drop.

 Use high-quality linear supplies to minimize noise.  Use an isolated type power supply to prevent LVDS common mode range violation.

Note: Camera performance specifications are not guaranteed if your power supply does not meet these requirements.

Input Signals, Camera Link

The camera accepts control inputs through the Camera Link MDR26F connector.

The camera ships in internal sync, internal programmed integration (exposure mode 7) TDI Mode.

EXSYNC (Triggers Frame Readout)

Frame rate can be set internally using the serial interface. The external control signal EXSYNC is optional and enabled through the serial interface. This camera uses the falling edge of EXSYNC to trigger pixel readout. Section Exposure Mode and Line/ Frame Rate for details on how to set frame times, exposure times, and camera modes.

Direction Control

You control the CCD shift direction through the serial interface. With the software command, scd, you determine whether the direction control is set via software control or via the Camera Link control signal on CC3. Refer to section Sett in g the Ca m era’s CCD Shift Direction for details.

Output Signals, Camera Link

These signals indicate when data is valid, allowing you to clock the data from the camera to your acquisition system. These signals are part of the Camera Link configuration and you should refer to the Teledyne DALSA Camera Link Implementation Road Map, available at Knowledge Center, for the standard location of these signals.

 The camera internally digitizes 12 bits and outputs 8 MSB or all 12 bits depending on

th e cam era’s Cam era Lin k operatin g m od e. Refer to 4.4.2 Setting the Camera Link Mode for details.

 For a Camera Link reference refer to Appendix A on page 114.

2.3 Camera Link Video Timing

The Piranha HS-xx camera has two different readout times. The first readout time is the

CCD Read ou t w here the cam era p ixels are rea d ou t into the cam er a’s linestore. The

second readout is the linestore readout where the linestore pixels are read out to your

3.3 Optical Interface

Illumination

The amount and wavelengths of light required to capture useful images depend on the particular application. Factors include the nature, speed, and spectral characteristics of objects being imaged, exposure times, light source characteristics, environmental and acquisition system specifics, and more.

It is often more important to consider exposure than illumination. The total amount of energy (which is related to the total number of photons reaching the sensor) is more important than the rate at which it arrives. For example, 5J/ cm2 can be achieved by exposing 5mW/ cm2 for 1ms just the same as exposing an intensity of 5W/ cm2 for 1s.

Light Sources

Keep these guidelines in mind when setting up your light source:  LED light sources are relatively inexpensive, provide a uniform field, and longer life

span compared to other light sources. However, they also require a camera with excellent sensitivity, such as the HS-xx camera.

 Halogen light sources generally provide very little blue relative to infrared light (IR).  Fiber-optic light distribution systems generally transmit very little blue relative to IR.  Some light sources age; over their life span they produce less light. This aging may

not be uniform—a light source may produce progressively less light in some areas of the spectrum but not others.

Filters

CCD cameras are extremely responsive to infrared (IR) wavelengths of light. To prevent infrared from d istortin g the im ages you scan , u se a ―hot mirror‖ or IR cu toff filt er that transmits visible wavelengths but does not transmit wavelengths over 750nm. Examples are the Schneid er Op tics™ B+W 489, which in clu des a m ou ntin g ring, th e CORION ™ LS750, which d oes not inclu d e a m ounting r in g, and th e CO RIO N ™ H R-750 series hot mirror.

Lens Modeling

Any lens surrounded by air can be modeled for camera purposes u sing three primary points: the first and second principal points and the second focal point. The primary points for a lens should be available from the lens data sheet or from the lens manufacturer. Primed quantities denote characteristics of the image sid e of the lens. That is, h is the object height and h is the image height.

The focal point is the point at which the image of an infinitely distant object is brought to focus. The effective focal length (f) is the distance from the second principal point to the second focal point. The back focal length (BFL) is the distance from the image side of the

03-032-20013-04 Teledyne DALSA

Piranha HS-xx RoHS User Manual

27

lens surface to the second focal point. The object distance (OD) is the distance from the first principal point to the object.

Software Interface: How to Control the Camera

All Piranha HS-xx camera features can be controlled through the serial interface. The camera can also be used without the serial interface after it has been set up correctly. Functions available include:

 Controlling basic camera functions such as gain and sync signal source.  Flat field correction.  Mirroring and readout control.  Generating a test pattern for debugging.

The serial interface uses a simple ASCII-based protocol and the PC does not require any custom software.

Note: This command set has changes from previous Teledyne DALSA cameras. Do not

assume that the Piranha HS commands perform similarly to older cameras.

Serial Protocol Defaults

 8 data bits  1 stop bit  No parity  No flow control  9.6kbps  Camera does not echo characters

Baud rate. Available baud rates are: 9600 (Default), 19200, 57600, and 115200.

Notes:

 Power-on rate is always 9600 baud.  The rc (reset camera) command will not reset the camera to

the power-on baud rate and will reboot using the last used baud rate.

Example:

sbr 57600

Command Format

When entering commands, remember that:

 A carriage return <CR> ends each command.  A space or multiple space characters separate parameters. Tabs or commas are invalid

parameter separators.

 Upper and lowercase characters are accepted  The backspace key is supported  The camera will answer each command with either <CR><LF> ―OK >" or

<CR><LF>"Error xx: Error Message >" or <CR><LF>―Wa rning xx: Warning Message >‖. The ">" is used exclusively as the last character sent by the camera.

The following parameter conventions are used in the manual:

• i = integer value

• f = real number

• m = member of a set

• s = string

• t = tap id

• x = pixel column number

• y = pixel row number

4.3 Sensor Output Format

4.3.1 Selecting TDI or Area Mode Operation

The Piranha HS-xx cameras have the ability to operate in both TDI and Area Mode. In Area Mode, the camera operates as an area array camera using a two dimensional array

of pixels. Area Mode is useful for aligning the camera to your web direction or when you need a rectangular 2D image and the lighting supports a full frame imager.

In TDI Mode, the camera operates as a TDI high sensitivity line scan camera and combines multiple exposures of an object into one high-resolution result.

The camera stores user settings for Area Mode and TDI Mode separately, allowing you to switch between Area and TDI mode without losing settings specific to each mode. See section 4.6 Saving and Restoring Settings for an explanation on how user settings are stored and retrieved.

NOTE: Sensor cosmetic specifications for Area Mode of operation are neither tested nor guaranteed

4.2 Selecting the Number of CCD Integration Stages

A note on stage selection (stg) and the HS-82 model of camera:

The sensitivity level of a camera can be adjusted by setting the number of CCD integration stages. For such purpose, the standard HS-80-08K80-00-R camera has six different allowable settings: 16, 32, 48, 64, 80 and 96. With modifications to the binning setup, the HS-82-04k80-00-R camera retains this feature of the standard camera, but the number of stages is halved (8, 16, 24, 32, 40 and 48) to reflect this change.

Purpose:

When in TDI Mode, selects the forward or reverse CCD shift direction or external direction control. This accommodates object direction change on a web and allows you to mount the camera ―u p sid e d ow n ‖.

In Area Mode, selects the vertical readout d irection. This allows you to mirror the image vertically or m ount the camer a ―u p sid e dow n‖.

Syntax:

Readout direction. Allowable values are:

0 = Forward CCD shift direction. 1 = Reverse CCd shift direction. 2 = Externally controlled direction control via Camera Link

control CC3 (CC3=1 forw ard, CC3=0 reverse). Available only in TDI Mode.

Notes:

 The following user settings are stored separately for forward

and reverse direction; analog gain, analog offset, digital gain, digital offset, background subtract, and pixel coefficients. These settings are automatically loaded when you switch direction. All other settings are common to both directions.

 See the following figures for an illustration of CCD shift

direction in relation to object movement.

 Note that some commands that require longer processing

time, like ccg, delay implementation of an external direction change.

Purpose:

Increases the horizontal pixel pitch and light sensitivity by decreasing horizontal resolution. The amount of data being sent from the camera is reduced by the horizontal binning factor. Different framegrabber files are needed for different horizontal binning factors.

Syntax:

sbh m

Syntax Elements:

m

Horizontal binning value. Available values are 1 (factory setting, no binning) 2, 4, or 8.

Notes:

 If you are using horizontal binning, the min, max, and mean

statistics generated by the gl or gla command are for every second pixel (or valid data) only (e.g., if sbh 2, every second pixel).

 For optimal flat field correction, you should rerun the ccp and

ccf commands after changing binning values.

 Changing binning values does not automatically alter gain,

frame rate generation, or other functions of the camera.

 Pixel numbering remains unchanged for the roi, gl, gla,

dpc, gfc, sfc, gpc, and spc commands. Refer to Figure 21

for an explanation of pixel numbering and pixel start and stop values when using a region of interest.

Example:

4.3.4 Increasing Sensitivity with Binning

Binn in g increases th e camera’s ligh t sensitivity by decrea sing h orizontal and/ or vertical

resolution—the charge collected by adjacent pixels is added together. Binning is also useful for increasing frame rate (vertical binning) or increasing the pixel pitch. For example, if you set your vertical binning to 2 and your horizontal binning to 2, your pixel size increases from 7µm x 7µm (no binning) to 14µm x 14µm (2x2 binning).

Vertical binning value. Available values (not including the HS-82 model) are 1

(factory setting, no binning) to 8. Available values for the HS-82 model are 1 to 4.

Notes:

 You will have to recalibrate the camera after changing binning

values.

 Increasing the vertical binning, decreases the maximum

allowable line rate. You may have to enter a new camera frame rate after changing vertical binning values if the current value becomes invalid. The camera sends a warning message in this situation.

Figure 21: Binning Start and End Values when using a Region of Interest

In this example a region of interest is set to include pixels 4 to 9 and horizontal binning is set to 2. Because pixel 3 is now included in the same data group as pixel 4, the region of interest will now include the data from pixel 3. Also, pixel 10 is included in the same data group as pixel 9, so pixel 10 is now part of the region of interest. To see how the region of interest start and stop values have been rounded, use the command get roi.

Setting Vertical Binning

A note on vertical binning (sbv) and the HS-82 model of camera:

Binning increases the camer a’s ligh t sensitivity by decr easing h orizonta l and / or ver tical resolution — the charge collected by adjacent pixels is added together. Binning is also useful for increasing frame rate (vertical binning) or increasing the pixel pitch.

The default binning setting (1 x 1) in the HS-82-04k80-00-R camera is essentially equivalent to performing 2 x 2 binning in standard HS-80-08K80-00-R camera. Horizontal binning is achieved by binning two adjacent columns together during the VCCD to HCCD transfer while vertical binning is achieved by transferring two VCCD rows into the enlarged HCCD prior to horizontal transfers. This difference translates the 1x - 8x

4.3.5 Exposure Mode and Line/Frame Rate

How to Set Exposure Mode and Line/Frame Rate

You have a choice of operating the camera in one of two exposure modes. Depending on your mode of operation, the cam era’s line/ fram e rate (syn ch r onization) can be generated internally through the software command ssf or set externally with an EXSYNC signal (CC1). When operating in TDI Mode, it is important that the line rate used matches the web speed. Failure to match the web speed will result in smearing.

To select how you want the camera’s line/frame rate to be generated:

Exposure Modes in Detail

When setting the frame rate (using the ssf command), exposure time will be reduced, if necessary, to accommodate the new frame rate. The exposure time will always be set to the maximum time (frame period – frame transfer time – pixel reset time) for that frame rate when a new frame rate requiring reduced exposure time is entered.

When setting the exposure time (using the set command), frame time will be increased, if necessary, to accommodate the exposure time. Under this condition, the frame periof will equal the Readout+Exposure Pulse+Exposure Time.

Frame rate is set by the period of the external trigger pulses. EXSYNC pulses faster than the read out time are ignored. The falling edge of EXSYNC marks the start of readout.

Note: In TDI mode the frame period equals the line period.

Mode 3: External Trigger, Maximum Exposure Time

Figure 23: Mode 3 Timing

In this mode, the external trigger rate sets both the frame rate and the exposure time. The rising pulse of the external trigger marks the beginning of the exposure time. Readout begins on the falling edge of EXSYNC. A charge dump occurs at the beginning of the exposure time, clearing any accumulated charge gathered up to this point. An external shutter or strobe should be used to remove light during readout.

Mode 7: Internal Frame Rate, Maximum Exposure Time

In this mode, the frame rate is set internally using the ssf command with a maximum exposure time.

Note: In TDI mode the frame period equals the line period.

4.4.1 How to Configure Camera Output

The Piranha HS cameras offer great flexibility when configuring your camera output. Using the clm com mand , you d eter m ine the camer a’s Cam era Link configuration, number of output taps, and bit depth. Using the sot command, you determine the cam era’s output rate. These tw o com mand s w ork together to determine your final camera output configuration.

You can further configure your readout using the smm com m and to select the ca m era ’s pixel readout direction.

The following tables summarize the possible camera configurations for each of the HS-xx camera models. Refer to the figure below for a description on how to select your camera output.

4.5.2 Analog and Digital Signal Processing Chain

Processing Chain Overview and Description

The follow ing diagr am sh ow s a simp lified block d iag ram of the ca m era ’s an alog and

digital processing chain. The analog processing chain begins with an analog gain adjustment, followed by an analog offset adjustment. These adjustments are applied to the video analog signal prior to its digitization by an A/ D converter.

The digital processing chain contains the FPN correction, the PRNU correction, the background subtract, and the digital gain and offset. All of these elements are user programmable.

Notes:

 FPN and PRNU correction is not available when operating the camera in Area Mode.

For details on how to switch camera operation modes, refer to section 4.5.1 .

 The following user settings are stored separately for forward and reverse direction;

analog gain, analog offset, digital gain, digital offset, and background subtract. They are saved using the wus command.

 FPN and PRNU coefficients are stored separately for forward and reverse direction.

To save the current PRNU coefficients, use the command wpc. To save the current FPN coefficients, use the command wfc. Settings are saved for the current direction only.

Figure 29: Signal Processing Chain

Analog Processing

Optimizing offset performance and gain in the analog domain allows you to achieve a better signal-to-noise ratio and dynamic range than you would achieve by trying to optimize the offset in the digital domain. As a result, perform all analog adjustments prior to any digital adjustments.

1. Analog gain is multiplied by the analog signal to increase the signal strength before

the A/ D conversion. It is used to take advantage of the full dynamic range of the A/ D converter. For example, in a low light situation the brightest part of the image may be consistently coming in at only 50% of the DN. An analog gain of 6 dB (2x) will ensure full use of the dynamic range of the A/ D converter. Of course the noise is also increased.

2. The analog offset or bla ck lev el is an ―artificial‖ offset in trod u ced into th e vid eo p ath

to ensure that the A/ D will function properly. The analog offset should be set so that it is at least 3 times the rms noise value at the current gain.

Digital Processing

To optimize camera performance, digital signal processing should be completed after any analog adjustments.

1. Fixed pattern noise (FPN) calibration (calculated using the ccf command) is used to

subtract away individual pixel dark current.

2. The digital offset (sdo command ) enables the subtraction of the ―ar tificial‖ A/ D offset

(th e an alog offset) so th a t ap p lication of the P RN U coefficient d oesn’t resu lt in

artifacts at low light levels due to the offset value. You may want to set the sdo value if you are not using FPN correction but want to perform PRNU correction.

3. Photo-Response Non-Uniformity (PRNU) coefficients are used to correct the

difference in responsivity of individual pixels (i.e. given the same amount of light different pixels will charge up at different rates) and the change in light intensity across the image either because of the light source or due to optical aberrations (e.g. there many be more light in the center of the image). PRNU coefficients are

multipliers and are defined to be of a value greater than or equal to 1. This ensures that all pixels will saturate together. When using PRNU correction, it is important that the A/ D offset and Fixed Pattern Noise (FPN) or per pixel offsets are subtracted prior to the multiplication by the PRNU coefficient. The subtraction of these 2 components ensure that the video supplied to the PRNU multiplier is nominally zero and zero multiplied by anything is still zero resulting in no PRNU coefficient induced FPN. If the offset is not subtracted from the video then there will be artifacts in the video at low light caused by the multiplication of the offset value by the PRNU coefficients.

4. Background subtract (ssb command) and system (digital) gain (ssg command) are

used to increase image contrast after FPN and PRNU calibration. It is useful for systems that process 8-bit data bu t w ant to tak e ad v anta ge of th e cam era’s 12-bit digital processing chain. For example, if you find that your image is consistently between 128 and 255DN(8-bit), you can subtract off 128 (ssb 2048) and then multiply by 2 (ssg 0 8192) to get an output range from 0 to 255.

Notes:

 All d igital settings (digital offset, FPN and PRNU

coefficients), digital gain, background subtract) should be turned off before calibrating analog gain to avoid unpredictable results.

 This function requires constant light input while executing.  To use this command, the CCD shift direction (scd) should

be set to forward (0) or reverse (1).

 If very few tap pixels are w ithin the ROI, gain calculation

may not be optimal.

 When all taps are selected, taps outside of the ROI are set to

the average gain of the taps that are within the ROI.

 Perform analog gain algorithms before performing FPN and

PRNU calibration.

Calibrating the Camera to Remove Non-Uniformity (Flat Field Correction)

Flat Field Correction Overview

This camera has the ability to calculate correction coefficients in order to remove non uniformity in the image when operating in TDI Mode. This video correction operates on a pixel-by-pixel basis and implements a two point correction for each pixel. This correction can reduce or eliminate image distortion caused by the following factors:

 Fixed Pattern Noise (FPN)  Photo Response Non Uniformity (PRNU)  Lens and light source non-uniformity

Correction is implemented such that for each pixel:

Brightest Pixel (per tap)

Darkest Pixel (per tap)

Note: If your illumination or white reference does not extend the full field of view of the camera, the camera will send a warning.

The algorithm is performed in two steps. The fixed offset (FPN) is determined first by performing a calculation without any light. This calibration determines exactly how much offset to subtract per pixel in order to obtain flat output when the CCD is not exposed.

The white light calibration is performed next to determine the multiplication factors required to bring each pixel to the required value (target) for flat, white output. Video output is set slightly above the brightest pixel (depending on offset subtracted).

Flat Field Correction Restrictions

It is important to do the FPN correction first. Results of the FPN correction are used in the PRNU procedure. We recommend that you repeat the correction when a temperature change greater than 10°C occurs or if you change the analog gain, integration time, binning, or number of integration stages.

PRNU correction requires a clean, white reference. The quality of this reference is important for proper calibration. White paper is often not sufficient because the grain in the white paper will distort the correction. White plastic or white ceramic will lead to better balancing.

For best results, ensure that:

1. 60 Hz ambient light flicker is sufficiently low not to affect camera

performance and calibration results.

2. For best results, the analog gain should be adjusted for the expected operating

conditions and the ratio of the brightest to darkest pixel in a tap should be less than 3 to 1 where:

The camera is capable of operating under a range of 8 to 1, but will clip values larger than this ratio.

3. The brightest pixel should be slightly below the target output.

4. When 6.25% of pixels from a single row within the region of interest are

clipped, flat field correction results may be inaccurate.

5. Correction results are valid only for the current stage selection. If you change

the number of stages, it is recommended that you recalculate your coefficients.

6. Correction results are valid only for the current analog gain and offset values.

If you change these values, it is recommended that you recalculate your coefficients.

Purpose:

Performs PRNU correction to a camera calibrated peak value and eliminates the difference in responsivity betw een the most and least sensitive pixel creating a uniform response to light. For a complete description on how to use this command, see the Flat Field Correction Overview on page 57.

Syntax

ccp

Notes:

 Perform all analog adjustments before calculating PRNU.  Perform FPN correction before PRNU correction.  If FPN cannot be calibrated, use the rpc command to reset all

coefficients to zero, and save them to memory with the wpc command. You can then adjust the digital offset (sdo command) to remove some of the FPN.

 The ccp command is not available when the camera shift

direction is externally controlled. Direction control must be stable while the camera is calculating coefficients (see Direction Control on page 21).

 Ensure camera is operating at its expected analog gain,

integration time, and temperature.

 To avoid losing your current direction coefficients, you must

save the PRNU coefficients using the command wpc before changing camera shift direction or changing from TDI to Area Mode.

 Available in TDI Mode only.  Executing these algorithms causes the ssb command to be

set to 0 (no background subtraction) and the ssg command to 4096 (unity digital gain). The pixel coefficients are disabled (epc 0 0) during the algorithm execution but returned to the state they were prior to command execution.

Purpose:

Performs PRNU calibration to user entered value and eliminates the difference in responsivity between the most and least sensitive pixel creating a uniform response to light. Using this command, you must provide a calibration target.

Executing these algorithms causes the ssb command to be set to 0 (no background subtraction) and the ssg command to 4096 (unity digital gain). The pixel coefficients are disabled (epc 0 0) during the algorithm execution but returned to the state they were prior to command execution.

This algorithm is recommended for use only when FPN is negligible and FPN coefficients are set to zero. Since this

algorithm adjusts the analog gain, it also affects FPN. If FPN is calibrated prior to running this algorithm, FPN w ill be observable in dark conditions and an incorrect FPN value will be used during PRNU calibration resulting in incorrect PRNU coefficients.

2 = Calculates the PRNU coefficients using the entered target value as shown below:

PRNU Coefficient =

(AVG Pixel Value ) - (FPN + value)sdo

i

The calculation is performed for all sensor pixels but warnings are only applied to pixels in the region of interest. This algorithm is useful for achieving uniform output across multiple cameras. Is is important that the target value (set with the next parameter) is set to be at least equal to the highest pixel across all cameras so that all pixels can reach the highest pixel value during calibration.

3 = This algorithm includes an analog gain adjustment prior to PRNU calibration. Analog gain is first adjusted so that the peak pixel va lu e in tap ’s ROI is within 97 to 99% of the specified target value. It then calculates the PRNU coefficients using the target value as shown below:

PRNU Coefficient =

Target

(AVG Pixel Value ) - (FPN + value)sdo

i

The calculation is performed for all sensor pixels but w arnings are only applied to pixels in the region of interest. This algorithm is useful for achieving uniform output across multiple cameras.

This algorithm is useful for achieving uniform output across multiple cameras by first adjusting analog gain and then performing PRNU calibration. This algorithm is recommended for use only w hen FPN is negligible and FPN coefficients are set to zero. Since this algorithm adjusts the analog gain, it also affects FPN. If FPN is calibrated prior to running this algorithm, FPN w ill be observable in dark conditions and an incorrect FPN value will be used d uring PRNU calibration resulting in incorrect PRNU coefficients.

This algorithm is more robust and repeatable than algorithm 1 because it uses an average pixel value rather than a number above target. However, this algorithm is slow er.

4 = Calculates the PRNU coefficient in the same way as cpa 2 with the exception that this command only calculates PRNU for pixels within the current Region of Interest (ROI).

i2

Peak target value in a range from 1024 to 4055DN. The target value must be greater than the current peak output value.

Notes:

 Perform all analog adjustments before calibrating PRNU.  This command performs the same function as the cpp

command but forces you to enter a target value.

 Calibrate FPN before calibrating PRNU. If you are not

performing FPN calibration then issue the rpc (reset pixel coefficients) command and set the sdo (set digital offset) value

Figure 32: Saving and Restoring Overview

Factory Settings

You can restore the original factory settings, including the factory calibrated pixel coefficient set, at any time using the command rfs.

User Settings

There are two main sets of user settings: Area Mode user settings and TDI Mode user settings. After issuing the user settings save command, wus, settings are saved depending on which mode the camera is operating in when the command is issued. Also, when operating in TDI Mode, analog gain and offset, digital gain and offset, and background subtract values are saved as distinct values for Forward and Reverse directions. In other words, you can program the camera to operate with an analog gain value of +5d b in Forward direction and an analog gain value of +3db in Reverse direction. Forward and Reverse direction settings are saved simultaneously with the wus command. Note that when you switch directions, the settings saved for that direction are automatically loaded.

You can save or restore your user settings to non-volatile memory using the following commands.

 To save all current user settings to EEPROM for the current mode for both TDI shift

directions, use the command wus. The camera will automatically restore the saved user settings when powered up.

WARNING: While settings are being written to nonvolatile memory, do not power down camera or camera memory may be corrupted.

 To restore the last saved user settings, including the last used pixel coefficient set, for

the current mode, use the command rus.

4.6.2 Saving and Restoring PRNU and FPN Coefficients

Pixel coefficient sets are saved separately for Forward and Reverse direction, depending on which direction the camera is operating in when the wpc or wfc command is issued. It is important that you save pixel coefficients before switching CCD shift direction or current coefficient values will be lost.

Parameters

Description

calculate PRNU algorithm

cpa

i1 i2

Performs PRNU calibration according to the selected algorithm.

The first parameter is the algorithm where i1 is:

1 = This algorithm first adjusts each tap’s an alog gain so th at 8-13% of pixels within a tap are above the value specified in the target value parameter. PRNU calibration then occurs using the peak pixel in the region of interest. (Identical to ccp)

2 = Calculates the PRNU coefficients using the entered target value as shown below:

PRNU Coefficient =

Target

(AVG Pixel Value) - (FPN+ value)sdo

The calculation is performed for all sensor pixels but warnings are only applied to pixels in the region of interest. This algorithm is useful for achieving uniform output across multiple cameras.

3 = This algorithm includes an analog gain adjustment prior to PRNU calibration. Analog gain is first adjusted so that the peak p ixel value in tap ’s ROI is within 97 to 99% of the specified target value. It then calculates the PRNU coefficients using the target value as shown below:

PRNU Coefficient =

Target

(AVG Pixel Value ) - (FPN + value)sdo

i

The calculation is performed for all sensor pixels but warnings are only applied to pixels in the region of interest. This algorithm is useful for achieving uniform output across multiple cameras.

4 = This algorithm is the same as 2 with the exception that it only calculates PRNU for the pixels within the current Region of Interest (ROI).

The second parameter, i2, is the target value to use in a range from 1024 to 4055DN.

Camera Link™ Reference,

Timing, and Configuration Table

Camera Link is a communication interface for vision applications. It provides a connectivity standard between cameras and frame grabbers. A standard cable connection

will r edu ce manufactu rer s’ sup por t time and greatly red uce the level of com plexity and

time needed for customers to successfully integrate high speed cameras with frame grabbers. This is particularly relevant as signal and data transmissions increase both in complexity and throughput. A standard cable/ connector assembly will also enable customers to take advantage of volume pricing, thus reducing costs.

The camera link standard is intended to be extremely flexible in order to meet the needs of different camera and frame grabber manufacturers.

The Teledyne DALSA Camera Link Implementation Road Map (available from the

Knowledege Center on Teledyne DALSA website) details how Teledyne DALSA

standardizes its use of the Camera Link interface.

LVDS Technical Description

Low Voltage Differential Signaling (LVDS) is a high speed, low power, general purpose interface standard. The standard, known as ANSI/ TIA/ EIA-644, was approved in March

1996. LVDS uses differential signaling, with a nominal signal swing of 350mV differential. The low signal swing decreases rise and fall times to achieve a theoretical maximum transmission rate of 1.923 Gbps into a loss-less medium. The low signal swing also means that the standard is not dependent on a particular supply voltage. LVDS uses currentmode drivers, which limit power consumption. The differential signals are immune to ±1 V common volt noise.

Camera Signal Requirements

This section provides definitions for the signals used in the Camera Link interface. The standard Camera Link cable provides camera control signals, serial communication, and video data.

Video Data

The Channel Link technology is integral to the transmission of video data. Image data and image enable signals are transmitted on the Channel Link bus. Four enable signals are defined as:

• FVAL—Frame Valid (FVAL) is defined HIGH for valid lines.

• LVAL—Line Valid (LVAL) is defined HIGH for valid pixels.

Piranha HS-xx RoHS User Manual

96

CC1

EXSYNC, negative edge active

CC2

Not Used

CC3

Forward

CC4

Not Used

• DVAL—Data Valid (DVAL) is defined HIGH when data is valid.

• Spa re— A spare has been defined for future use.

All four enable signals must be provided by the camera on each Channel Link chip. All unused data bits must be tied to a known value by the camera. For more information on image data bit allocations, refer to the official Camera Link specification located here, on the Teledyne DALSA website.

Camera Control Signals

Four LVDS pairs are reserved for general purpose camera control. They are defined as camera inputs and frame grabber outputs. Camera manufacturers can define th ese signals to meet their needs for a particular product. The signals are:

• Cam era Control 1 (CC1)

• Cam era Control 2 (CC2)

• Cam era Control 3 (CC3)

• Cam era Control 4 (CC4)

The HS-xx uses the following camera control signals:

Table 24: Teledyne DALSA Camera Control Configuration

Communication

Two LVDS pairs have been allocated for asynchronous serial communication to and from the camera and frame grabber. Cameras and frame grabbers should support at least 9600 baud. These signals are

• SerTFG—Differential pair with serial communications to the frame grabber.

• SerTC—Differential pair with serial communications to the camera.

The serial interface will have the following characteristics: one start bit, one stop bit, no parity, and no handshaking. It is recommended that frame grabber manufacturers supply both a user interface and a software application programming interface (API) for using the asynchronous serial communication port. The user interface will consist of a terminal program with minimal capabilities of sending and receiving a character string and sending a file of bytes. The software API will provide functions to enumerate boards and send or receive a character string.

Power

Power will not be provided on the Camera Link connector. The camera will receive power through a separate cable. Camera manufacturers will define their own power connector, current, and voltage requirements.
