Flat Field Correction Feature Descriptions
Display Name Feature & Values Description Standard
& View
Flat Field Correction Mode flatfieldCorrectionMode Sets the mode for the Flat Field correction.
Beginner
DFNC
Off Off Flat Field Correction is disabled.
Active Active Flat Field Correction is enabled.
Calibration Calibration When this mode is selected, the camera is
configured for flat field correction calibration. The
device may automatically adjust some of its
features when calibrate 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 feature is
changed from Calibrate mode to another mode.
Flat Field Correction Current
Active Set flatfieldCorrectionCurrentActiveSet Specifies the current set of Flat Field coefficients to
use.

Factory Flatfield FactoryFlatfield Sets the factory Flat Field coefficient table as the
current Flat Field.
User Flatfield 1 UserFlatfield1 Sets User Flat Field 1 coefficient table as the
current Flat Field.
User Flatfield 2 UserFlatfield2 Sets User Flat Field 2 coefficient table as the
current Flat Field.
User Flatfield 3 UserFlatfield3 Sets User Flat Field 3 coefficient table as the
current Flat Field.
User Flatfield 4 UserFlatfield4 Sets User Flat Field 4 coefficient table as the
current Flat Field.
Flat Field Correction Type flatfieldCorrectionType Specifies the Flat Field correction type.

Line-Based LineBase Flat field correction is based on a single line of gain
and offset coefficients.
Flat Field Correction
Algorithm flatfieldCorrectionAlgorithm Specifies the Flat Field correction algorithm to use.
Guru
DFNC
Method 1 Method1 The following formula is used to calculate the flat
field corrected pixel: newPixelValue[x][y] =
(sensorPixelValue[x][y] - FFCOffset[x] [y]) *
FFCGain[x] [y]
Flat Field Calibration
Algorithm flatfieldCorrectionCalibrationAlgorithm Specifies the flatfield calibration algorithm to use.

DFNC
Peak Peak Each pixel is gained up to the brightest.
Set Target Target Each pixel is gained up to the value specified in the
flatfieldCalibrationTarget feature.
Flat Field Calibration Target
(in DN) flatfieldCalibrationTarget Sets the target pixel value for the gain (PRNU)
calibration. Expert
