select the color or colors you want to adjust. This allows
you to limit the calibration to a single color.
•
Perform all analog and digital adjustments before
performing FPN correction.
•
Perform FPN correction before PRNU correction.
To save FPN coefficients after calibration, use the wfc command.
ccp, wfc
ccf
Sets an individual pixel's FPN coefficient.
sfc x i
x
The pixel number from 1 to sensor pixel count.
i
Coefficient value in a range from 0 to 4095 (12 bit LSB).
Before sending this command, use the scl command to select the
color you want to adjust.
sfc 10 50
Sets a range of pixel FPN coefficients.
sfr x x i
x
The first pixel number of the range.
x
The last pixel number of the range.
i
Coefficient value in a range from 0-2048.
•
Before sending this command, use the
select the color you want to adjust.
The first pixel of the range must be less than the last.
sfr 1 100 80
Calculate the PRNU coefficients to eliminate the difference in
responsivity between the pixels, thereby creating a uniform response
to light. Using this command, you must provide a calibration target.

PRNU calibration algorithm to use:
1 = This algorithm first adjusts each tap's analog gain so that
8-13% of pixels within a tap are above the value specified in
the target value parameter. PRNU calibration then occurs using
the peak pixel in the region of interest.
This algorithm is recommended for use only when FPN is
