2.2 Image Sensor
The Eliixa+ 8k sensor is composed of two pairs of sensitive lines. Each pair of lines use the same Analog to Digital Column converter
(ADC Column). An appropriate (embedded)
Time delay in the exposure between each line allows combining two successive exposures in order to double the sensitivity of a single line.
This Time Delay Exposure is used only in the
4S multi-line modes (4 Lines) and also in the three binning modes, as described below.
The 8192 Pixels of the whole sensor are divided in 2 blocks of 4096 pixels.

6 CAMERA SOFTWARE INTERFACE
6.1 Control and Interface
As all the e2v Cameras, the ELIIXA+ CL is delivered with the friendly interface control software
COMMCAM.UCL (as “Ultimate Camera Link”) which is based on the GenICam standard
COMMCAM recognizes and detects automatically all the UCL Cameras connected on any transport layers
(Camera Link or COM ports) of your system.
Once connected to the Camera you have an easy access to all its features. The visibility of these features can be associated to three types of users: Beginner, Expert or Guru. Then you can make life easy for simple users.
Minimum version of CommCam is 2.1.4 in order to recognize the ELIIXA+ 8k/4k Camera (both versions)
The Versions “BHx” require a CommCam version 2.5.1 and further.
U SER M ANUAL ELIIXA+ 8 K /4 K CL M ONO – R EV H – 03/2016 P A G E | 17
6.2 Serial Protocol and Command Format
The Camera Link interface provides two LVDS signal pairs for communication between the camera and the frame grabber. This is an asynchronous serial communication based on RS-232 protocol.
The serial line configuration is:
Full duplex/without handshaking
9600 bauds (default), 8-bit data, no parity bit, 1 stop bit. The baud rate can be set up to 115200
6.2.1 Syntax
Internal camera configurations are activated by write or readout commands.
The command syntax for write operation is: w <command_name> <command_parameters><CR>
The command syntax for readout operation is: r <command_name><CR>
6.2.2 Command Processing
Each command received by the camera is processed:
The setting is implemented (if valid)
The camera returns “>”<return code><CR>
The camera return code has to be received before sending a new command.
The camera return code has to be received before sending a new command. Some commands are longer than the others : Waiting for the return code ensure a good treatment of all the commands without saturating the buffer of the camera
The Camera Returned Codes are :
Returned code meaning
>0
>3
>16
>33
>34
>35
(or “>OK”) : All right, the command will be implemented
Error Bad CRC (for write command only)
Invalid Command ID (Command not recognized or doesn't exist)
Invalid Access (the receipt of the last command has failed).
Parameter out of range (the parameter of the last command sent is out of range).
Access Failure (bad communication between two internal devices).
6.2.3 GenICam ready
The CameraLink Standard is not yet compliant with GenICam Standard, but as much as possible, each command of the ELIIXA+ will have its correspondence with the Standard Feature Naming Convention of the GenIcam Standard.
This correspondence is given in parenthesis for each feature/command as the following example :

When the Light source is enough to use the “1S” mode of the Sensor (one single line), the best is to use 2 lines (“2S” mode) and then to divide the result by two by using the Multi-
Line Gain set at “x0,5” :
In this case, the Full Well capacity is multiplied by x2 (two output registers are used) but the noise divided by √2 therefore the SNR is improved by a factor of √2.
Reverse Reading (X) ( ReverseReading ) : Allows to output the line in the Reverse-X direction. This value is available in the CommCam “Image Format Control” section :
Read function : “r revr”;
Return by the Camera : 0 or 1 (enabled/disabled)
Write function : “w revr <value>”;
“0” : Disabled.
“1” : Enables the reverse reading out (see below for “normal” direction)
Scan Direction ( ScanDirection ) : Set the scan direction for the sensor. This value is available in the
CommCam “Image Format Control” section :
Read function : “r scdi”;
Return by the Camera : 0, 1 or 2 (Forward/reverse/external)
Write function : “w scdi <value>”;
“0” : Forward.
“1” : Reverse
“2” : Externally controlled (by CC3 of the CameraLink Sync signals)
Forward/reverse information has to be set correctly as soon as the Mode “2S”, “4S” or 2SB of the sensor are set : In these modes, the sensor/Camera need to know what is the real order of the lines for the exposure delays.

If the Camera is in 4S Sensor mode, after changing of the scanning direction, the 5 first following triggers will be ignored in order to reinitialize the
“Full Exposure Control” mode. Then the 3 following lines acquired will be more or less black because in
4S, 4 lines are required for a complete exposure.
In 2S or 2SB Sensor modes, no Trigger will be lost after the change of scanning direction but the first line acquired will be more or less black as in 2S, 2 lines are required for a complete exposure.
In 1S, 1SB or 4SB modes, nothing is lost an all lines received after the delay are correct.
This positioning takes also in account that the mode “Reverse X” is “Off” (Normal readout direction)
Test Image Selector ( TestImageSelector ) : Defines if the data comes from the Sensor or the FPGA

7.3 Acquisition Control
This section deals with all the Exposure, Line period and synchronisation modes
Synchronisation Mode ( TriggerPreset ) : Timed or Triggered, it defines how the grabbing is synchronized. This command is available in the CommCam “Acquisition Control” section :
Read function : “r sync”;
Returned by the camera :
“0” : Internal Line Trigger with Exposure time Internally Controlled (Free Run). Not available when Sensor mode is set in “4S” (whatever the firmware version)
“1” : External Trigger with Exposure Time Internally Controlled. Available also when Sensor mode is set in “4S”.
“2” : External Trigger with maximum Exposure time
“3” : One External with Exposure Time Externally Controlled. The same Trigger signal defines the line period and its low level defines the exposure time. Available also when
Sensor mode is set in “4S”
“4” : Two External Triggers with Exposure Time Externally Controlled : CC2 defines the start of the exposure (and also the start Line) and CC1 defines the Stop of the exposure. Not available when Sensor mode is set in “4S”
“5” : Internal Line Trigger with maximum Exposure Time
Write function : “w sync” <value>
The Timing diagrams associated to each Synchronization mode and the Timing values associated are detailed in the APPENDIX B of this document.
Exposure time ( ExposureTime ): Defines the exposure time when set in the Camera. This command is available in the CommCam “Acquisition Control” section :
Read function : “r tint”;
Returned by the camera : Integer from 15 to 65535 (=1,5µs to 6553,5µs by step o 0,1µs)
Write function : “w tint” <value> ;
This value of exposure time is taken in account only when the synchronisation mode is “free run” (0) or “Ext
Trig with Exposure time set” (1). Otherwise it’s ignored.
Due to the limitation of the timing pixel inside the sensor, the Exposure time has to be set by taking in account the limitation detailed in the APPENDIX B of this document.
The Minimum exposure time which can be set is 1,5µs
Line Period ( LinePeriod ) : Defines the Line Period of the Camera in Timed mode. This command is available in the CommCam “Acquisition Control” section :
Read function : “r tper”;
Returned by the camera : Integer from 1 to 65536 (=0,1µs to 6553,6µs by step o 100ns)
Write function : “w tper” <value> ;
U SER M ANUAL ELIIXA+ 8 K /4 K CL M ONO – R EV H – 03/2016 P A G E | 28
The line period is active only in Free Run modes. It’s also disabled if in this mode, the Integration time is set higher than the Line Period.
The Tables of the minimum Line Period (Max Line Rate) versus the Data rate and the output mode chosen are given in Appendix C of this document.
Trigger Too Slow : Defines the Time limit (in ms) for the Camera to consider that the Incoming trigger is too slow. This command is available in the CommCam “Acquisition Control” section :
Read function : “r tgts”;
Returned by the camera : Integer from 1 to 5368 (1 to 5368 milliseconds by step of 1ms)
Write function : “w tgts” <value> ;
Trigger too Slow
By default, the trigger is considered too slow after 1000ms of missing Incoming Trigger.
This limit can be tuned now by the User. This tuning is particularly important when the camera is in 4S with the Exposure control active and the Control Exposure mode set in “4S
Only” : In this mode the incoming Line Period is delayed from one line to be reproduced in the camera after an exact measurement of the Line Period. If the trigger stops for a period of time below the limit, this will considered as a “long time Line” and not a stop : Then the next line will be delayed from the same value with the risk to loose new incoming triggers.
The Trigger too Slow limit has to be set at a value which is considered in the Application as the minimum value for a real stop in the incoming trigger.
Full Exposure Control Mode : set the behaviour of the Full Exposure Control Mode when active .
This value is available in the CommCam “Image Format Control” section :
Read function : “r stbm”;
Return by the Camera : Integer from 0 to 2
Write Function : “w stbm <value>”
“0” : Mode 4S/2S With all Lines at the Switch
“1” : Mode 4S/2S Without incorrect Lines at the Switch
“2” : 4S Only
This parameter is not available if the Sensor Mode is not 4S.
In addition, it has no effect if the Synchronization mode is not in Exposure Controlled (in 4S)
U SER M ANUAL ELIIXA+ 8 K /4 K CL M ONO – R EV H – 03/2016 P A G E | 29
The Full Exposure Control
In 4S Sensor Mode, the Sensor is working as a double TDI (Time Integration Delay) : The two Top
Pixels and the two bottom Pixels are working together in TDI with a delay between their exposure and outputting by the same Memory node and ADC. The summation of the pixels is done in the
“charge domain” before the Digital Conversion.
In TDI, control of the exposure is not possible: Only the full Exposure during the Line Period is possible. In order to allow the User to control the exposure in this 4S Sensor mode (Synchronization
Modes 1 and 3, described in the Acquisition control chapter), The ELIIXA+ Camera implement a “Full
Exposure Control Mode” :
Switch Point
When the User selects a synchronization mode which requires the control of the exposure, the camera enters a specific mode:
The Line Period (measured) is Tper, its minimum value is TPer mini
(10µs on this camera) and the exposure time set by the User is Prog_Tint.
If Tper < Prog_Tint
Not relevant. Prog_Tint has to be smaller than Tper.
The sensor is in full exposure and the gain applied on the output is fixed by the User = G stb
(max. x4)
If Tper < 4 x Max (TPer mini
, Prog_Tint) + 10µs
The Sensor works in Full Exposure during the whole Line Period (LP) and the gain applied on the output is variable (max x 4), set by User = G stb
The Output is multiplied by the following Gain = G stb
If Tper >= 4 x Max (TPer
x Prog_Tint / Tper mini
, Prog_Tint) + 10µs
The Sensor Switches in a specific 2S mode (equivalent)
The exposure is now controlled as the sensor doesn’t work in “TDI” mode.
The Exposure applied is = 4 x Prog_Tint + 1.9µs
A fixed Gain of x2 is applied on the output to ensure the continuity with the output before the switch
U SER M ANUAL ELIIXA+ 8 K /4 K CL M ONO – R EV H – 03/2016 P A G E | 30
Full Exposure Control Mode
During the 4S => 2S transition and the 2S => 4S transition (passing at the switch point) two “bad” lines
appear (either too dark or too bright). You can remove these lines by using the following parameter:
4S Only : The sensor doesn’t switch in 2S. The result is that , maybe after a short saturation, the level decreases as the Line Period increases. This mode is the best one if the Line period varies but doesn’t increase that much after the switch point (4 x Max (TPer mini
, Prog_Tint) + 10µs)
“Without all Lines” : The Switch 4s 2S is made in the conditions described above. All the lines are sent, even the double dark or double white at the transition (depending on the direction of the transition).
“Without Incorrect Lines” : The Switch 4s 2S is made in the conditions described above. The double dark or double white lines at the transition (depending on the direction of the transition) are removed (not sent) : Two lines triggered will miss in the LVAL signal.
Gain for the “Full Exposure Control Mode”
G stb
: The User Can set this Gain with a value up to x4 (Gain Section). The value recommended is the one which allows to cover the variation of the line period : 10% of variation requires a Gain at least of x1.2 (+/- 10%).
By default this value is set at x4.
Gain Full Exposure Control (G stb
): Set the Gain for the Control of Full Exposure Mode . This value is available in the CommCam “Gain & Offset” section :
Read function : “r stbg”;
Return by the sensor : value of the Gain between 0 and 49151
Write Function : “w stbg <value>”
<value> = Gain between 0 and 49151 (Gain = 1 + <value>/16384)

The ROI Gain feature comes in addition with the FFC (it’s applied and calculated after).
The maximum complementary Gain ix x2.
It can be applied in 2 commands :

Second, set the ROI (Region of Interest).
This second command applies the Gain on the ROI in memory and this is immediately activated.
The ROI Gain is a “live” feature that can be overlapped but can’t be saved in memory.
Here is an example to apply a complementary gain of x1,5 (512) between the pixels #3051
(0x0BEB) and #4102 (0x1006), pixels included. The two commands are :

8.1 Flat Field Correction
How is performed the Flat Field Correction ?
What is the Flat Field correction (FFC) ?
The Flat Field Correction is a digital correction on each pixel which allows :
To correct the Pixel PRNU (Pixel Response Non Uniformity) and DSNU (Dark Signal Non
Uniformity)
To Correct the shading due to the lens
To correct the Light source non uniformity
Before After
How is calculated / Applied the FFC ?
The FFC is a digital correction on the pixel level for both Gain and Offset.
Each Pixel is corrected with :
An Offset on 10 bits (Signed Int S9.1). They cover a dynamic of
256LSB in 12bits with a resolution of 1/2 LSB 12bits. Offet : the MSB is the sign, the rest of 9bits is from 0 .. 256 with precision of 1/2
A Gain on 12 bits (Unsigned Int U2.12) with a max gain value of x5
(*)
The calculation of the new pixel value is : P’ = ( P + Off).(1 + Gain/1024 (*) ). Gain : 0 to 4095
The FFC processing can be completed with an automatic adjustment to a global target. This function is designed as “FFC Adjust”. This adjustment to a User target is done by an internal hidden gain which is re-calculated each time the FFC is processed while the FFC adjust function is enabled.
The FFC is always processed with the max pixel value of the line as reference. If enabled, the
FFC adjust module (located at the output of the FFC module) calculates the adjustment gain to reach the target defined by the User.
When the FFC result is saved in memory, the adjust gain and target are saved in the same time in order to associate this gain value with the FFC result.
(*) : Up to the firmware version 1.0.1 (BA0) or 1.0.3A (BA1), the Gain resolution was : 1 +
Gain/8192 with a range limited at x3

PRNU Calibration
The User must propose a white/gray uniform target to the Camera (not a fixed paper) or you can set the Low Pass Filter to remove unwanted defect from the target.
The Gain/Light conditions must give a non saturated image in any Line.
The Camera must be set in the final conditions of Light/ Gain and in the final position in the System.
I f required, set a user target for the FFC adjust and enable it.
White uniform (moving) target. Use The FFC Low Band Filter if the Target can’t move. This will remove the defects of the target itself
Launch the FFC
Enable the FFC
You can save the FFC result (both FPN+PRNU in the same time) in one of the 4 x FFC
User Banks.
The user target and Gain are saved with the associated FFC in the same memory.
Advices
The ELIIXA+ Cameras have 8 x FFC Banks to save 8 x different FFC calibrations. You can use this feature if your system needs some different conditions of lightning and/or Gain because of the inspection of different objects : You can perform one FFC to be associated with one condition of Gain/setting of the Camera ( 4 Max) and recall one of the four global settings
(Camera Configuration + FFC + Line Quarters Balance) when required.

Write function : “w tfad <value>” : Set the Target Value (in 12bits)
FFC Adjust : A good usage.
When there are several Cameras to set up in a system on a single line, the most difficult is to have a uniform lightning whole along the line.
If each Camera performs its own Flat field correction, relative to the max of each pixel line, the result will be a succession of Camera lines at different levels.
=> The FFC Adjust function allows to set the same target value for all the Cameras in the system and then to get a perfect uniform line whole along the system with a precision of 1
LSB to the Target.
The Maximum correction is x2 the highest value of the line.

When you can’t provide a moving Target to the Camera during the PRNU Calibration you can setup the FFC
Low Band Filter in order to remove the defect from the Target before calculating the FFC parameters. The
Value set in the FFC filter defined the size of the interval around each pixel : The Filter will replace each pixel value by the average on the interval.
FPN/DSNU Calibration : o FPN Calibration Control ( FPNCalibrationCtrl ) : Launch or abort of the FPN process for the
Offsets calculation. These commands are available in the CommCam “Flat Field Correction /

Some Warnings can be issued from the PRNU/FPN Calibration Process as “pixel Overflow” of
“Pixel Underflow” because some pixels have been detected as too high or too low in the source image to be corrected efficiently.
The Calculation result will be proposed anyway as it’s just a warning message.

Digital Conversion : During the conversion, the analog Gain is applied by the gradient of the counting ramp
(see next chapter : Gain & Offset). The conversion time depends on the pixel format :
8 or 10 bits : 6µs
