Description
Initiates the FPN calibration process. Saves
average line (of
flatfieldCalibrationSampleSize rows). This is
the first user correction applied – it is
subtracted from each line.
This feature may not be of use to many
users as the camera already subtracts true
"dark current", but it may be useful for some
to provide a per pixel offset correction.
Default value is 0 DN for each pixel
