Gain(PRNU)
Calibration
flatfieldCalibrationPRNU
Performs photo response non-uniformity
(PRNU) calibration. (W)
PRNU calibration eliminates the difference
in responsivity between the most and least
sensitive pixel, creating a uniform
response to light. Pixels that fall outside
gain range of 1 to 4 for their color are
marked as defective.

Save Calibration
flatfieldCalibrationSave
Saves the current flat field coefficients in
the Active Set to the corresponding non-
volatile memory. (W) The color camera
also stores the individual color gains and
system gain. Write when in Calibration
Mode.

d
The FFC base + integration time scaled
delta offset value (FPN) above which the
pixel are deemed hot pixels and replaced.
This value can be adjusted to replace
more or fewer pixels. (RW)
Possible values are:1 to 4096, as float
