Values
Off
- Flat Field correction disabled
ActiveAll
- FPN and PRNU correction is active
ActiveFPNOnly
- FPN correction is active
ActivePRNUOnly
- PRNU correction is active
Calibration
- The camera is configured to calibration mode(Only available when
TriggerMode=Off, flatfielCorrectionCurrenActiveSet is not FactoryFlatfield, and width and
height are maximized). The device may automatically adjust some features in the camera
when calibration mode is enabled. The features that are automatically adjusted are device
specific. The device will not restore these features when the flat field correction mode is
changed from calibration mode to another mode. For example, width and height may be set
to the maximum sensor size when the flat field calibrate mode is enable.
Notes
Sets the mode for the flatfield correction.

Notes
The following formula is used to calculate the flatfield corrected pixel:
Mono camera:
newPixelValue
x,y
= (sensorPixelValue
x,y
– FFCOffset
x,y
) * FFCGain
[x][y]
Color camera:
newPixelValue
x,y
= (sensorPixelValue
x,y
– FFCOffset
x,y
) * FFCGain
x,y
* gain per color

Notes
Displays the flatfield gain mode that will was used in calibration.
High gain mode can apply a correction gain between 1 and 2 with reduced (9 bit) resolution.
High resolution can apply a correction gain between 1 and 1.5 with maximum (10 bit)
resolution
Refreshes when flatfieldCorrectionCurrentActiveSet, flatfieldCalibrationPRNU,
flatfieldCalibrationClearCoefficient, or flatfieldCoefficientsCopyInCurrent changes.
