Specifies the Y coordinate of the flat field
pixel coefficient to access. (RW) To
configure, set Correction Mode to
Calibration. Range: 1 to SensorHieght
Sets the gain to apply to the currently
selected pixel. Range is from 1 to 4, as
float.
To configure, set Correction Mode to
Calibration.
Sets the offset to apply to the currently
selected pixel. It is measured at the
minimal exposure time at dark.
To use, set the Correction Mode feature to
Calibration.
Sets the offset to apply to the currently
selected pixel. Measured at the current
exposure time at dark with a subtraction of
flatfieldCorrectionOffsetBase.
Range is 0 to 511, as float.
Read-Write when in Calibration Mode.
This feature is used to clear all the current
FPN and PRNU coefficients in the
selected Active Set. (W)
Read-Write when in Calibration Mode
This feature selects the FPN calculation
method. (RW)
When the Offset Calibration is
commanded, the base FPN value and the
delta FPN value are calculated.
When the Offset Calibration is
commanded the base FPN value is
calculated and not the delta FPN. The
purpose is to enable calibration with a
small amount of light to avoid the nonlinear
behavior near zero illumination. A
recommended illumination level is 50 DN.
Performs fixed pattern noise (FPN)
calibration. FPN calibration eliminates
fixed pattern noise by subtracting all non-
uniformities and dark current to obtain
near 0 DN output in the dark (no light
exposed to the sensor). This currently can
take up to 5 minutes.
