Specifies the current set of Flat Field coefficients to use.
User data is uploaded via the file access feature.
Feature used when flatfieldCorrectionMode is Active. In
Calibration, changing this feature has no effect unless
you save the FFC, where this feature defines where to
save the values. This feature also can be used to copy
FFC sets.
Sets the factory Flat Field coefficient table as the current
Flat Field.
Sets User Flat Field 1 coefficient table as the current Flat
Field.
Sets User Flat Field 2 coefficient table as the current Flat
Field.
Sets User Flat Field 3 coefficient table as the current Flat
Field.
Sets User Flat Field 4 coefficient table as the current Flat
Field.
Specifies the Flat Field correction type.
Flat field correction is based on an individual line
(FlatLine).
Specifies the Flat Field correction algorithm to use.
The following formula is used to calculate the flat field
corrected pixel: newPixelValue[x] = (sensorPixelValue[x]
- FFCOffset[x]) * FFCGain[x]
Specifies the flatfield calibration algorithm to use.
Basic Direct calculation of coefficients based on average line
values and target.
Apply a low pass filter to average line prior to calculating
coefficients. Used when target is not uniformly white or it
is not possible to defocus image.
Sets the target pixel value for the gain (PRNU)
calibration.
Set flat field calibration sample size (number of lines to
sum)

Sets the ROI Offset X
Sets the ROI Width
Performs Fixed Pattern Noise (FPN) calibration by
reducing to zero dark pixel current using a pixel offset.
No Error
FPN calibration failed.
The camera is busy and cannot perform the FPN
calibration.
The FPN calibration did not finished on time.
The camera cannot allocate the memory needed for FPN
calibration.
The FPN calibration was not able to reach the targets.
