Forward/Reverse
Forward/reverse information has to be set correctly For the re-ordering of the colors.
The Forward direction is defined as detailed below :
Note : The delay for the Camera to take in account a change in
the ScanDirection value is 200ms
This information can be set dynamically by using one of the two
External Trig lines (Line0 or Line1) of the GPIO connector
(change the direction “on the fly”).
In these case, the Trigger low level signification is :
“0” : Forward.
“1” : Reverse

Test Image Pattern Selector
This selection
Defines if the data comes from the normal Sensor operation and FPGA Chain or from digital patterns
generated at the end of the FPGA. This is mainly useful to detect some interfacing or connection issues.
To switch to Cmos sensor image
Grey Horizontal Ramp (Fixed) : See AppendixA
White Pattern (Uniform white image : 255)
Grey Pattern (Uniform middle Grey : 128 on each color)
RGBW Pattern See AppendixA
Grey vertical Ramp (moving)
When any of the Test pattern is enabled, the whole processing chain of the FPGA is disabled.
Note : When the camera is set with the RGBW pattern test, it’s no more taking in account the Line Trigger and
working in Free Run (line period controlled by the camera)
