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 For the
re-ordering of the colors.
The Forward direction is defined as detailed beside
:
Note : The delay for the Camera to take in account a
change in the ScanDirection value is minimum 100ms.
This information can be set dynamically by using the CC3
Trig signal of the CameraLink connector (change the
direction “on the fly”).
In these case, the Trigger level signification is :
“0” : Forward.
“1” :
Reverse
Test Image Selector
(
TestImageSelector
) :
Defines if the
data comes from the Sensor or the FPGA (test Pattern). This
command is available in the CommCam “Image Format”
section :
Read function : “r srce”;
Returned by the camera : “0” if Source from the Sensor and “1 to 5” if test pattern active
Write function : “w srce” <value> :
“0” : To switch to CCD sensor image
“1” :
Grey Horizontal Ramp (Fixed) : See AppendixA
“2” :
White Pattern (Uniform white image : 255)
“3” : Grey Pattern (Uniform middle Grey : 128 on each color))
“4” : Black Pattern (Uniform white image : 0)
“5” : Grey vertical Ramp (moving)
The test pattern is generated in the FPGA : It’s used to point out any interface problem with the Frame Grabber.
When any of the Test pattern is enabled, the whole processing chain of the FPGA is disabled.
Color Selection :
Disables each of the 3 colors.. This command is available in the CommCam “Image Format” section.
Read function : “r cold”;
Returned by the camera : Integer corresponding to one of the 3 different step values :
Bit 0 : Red color disabled if set to 1
Bit 1 : Blue color disabled if set to 1
Bit 2 : Green (both Green
Red
and Green
Blue
) color disabled if set to 1
Write function : “w cold” <val> ;
The Color Selection is not possible when the Camera output mode are full or Deca (8/10 Taps) Raw modes.
