The Flat Field controls, as shown by CamExpert, group parameters used to control the FPN and
PRNU calibration process.

Description
Off FPN and PRNU correction disabled.
On FPN and PRNU correction enabled.
Reset all FPN to 0 and all PRNU
coefficients to 1.
Selection between four different
PRNU algorithms.
Peak Calculation of PRNU coefficients to
bring all pixels to the peak.
PeakFilter A low pass filter is applied to the
average line values before calculating
the coefficients. Use this algorithm if
the calibration target is not uniformly
white or if it is not possible to defocus
the image. Because of the low pass
filter, this algorithm is not able to
correct pixel-to-pixel variations and
so it is preferable to use the "Peak"
algorithm.
Target
Calculation of PRNU coefficients to
bring all pixels to the target value.
