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 reasonable value for the User Target is not more than around 20% of the max value of the line.
