Correction Mode

flatfieldCorrectionMode

Sets the mode for flat field correction.

DFNC

Beginner

Off

Off Flat field correction is disabled.

Active

ActiveAll Flat field correction is enabled. FPN and PRNU

correction is active.

Active, FPN Only

ActiveFPNOnly FPN correction is active.

Active, PRNU Only

ActivePRNUOnly PRNU correction is active.

Calibration

Calibration The camera is configured to calibration mode

(Only available when TriggerMode=Off,

flatfielCorrectionCurrenActiveSet is not

FactoryFlatfield,).
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.
It is not available for FactoryFlatfield1 [Global

Shutter Factory Flat Field] ,FactoryFlatfield2

[Rolling Shutter Factory Flat Field].
It is not available for external mode, and it is

not available for smaller AOI than 2048

horonzatal.

Correction Algorithm

flatfieldCorrectionAlgorithm

Selects the algorithm to use for calibration of

flat field coefficients. <RO>

DFNC

Beginner

Method1

Method1 The following formula is used to calculate the

flatfield corrected pixel:
newPixelValuex,y = (sensorPixelValuex,y –

normalized FFCOffsetx,y) * FFCGain[x][y]

Correction Type

flatfieldCorrectionType

Specifies the flat field correction type. <RO>

DFNC

Beginner

Area-based

AreaBase Flat field correction is based on an entire image

(array)

Current Active Set

flatfieldCorrectionCurrentActiveSet

Specifies the current set of flat field coefficients

to use. This feature cannot be changed while

the camera is in flat field calibration mode.

Read-Write (Read-Only when in Calibration

Mode).
