cpa 1 600
Performs PRNU correction and eliminates the difference in
responsivity between the most and least sensitive pixel creating a
uniform response to light.
ccp
•
Before sending this command, use the scl command to
select the color or colors you want to adjust. This
allows you to limit the calibration to a single color.
•
Perform all analog adjustments before calculating
PRNU.
•
Perform FPN correction before PRNU correction.
•
If FPN cannot be calibrated, use the
reset all coefficients to zero, and save them to memory
with the wfc command. You can then adjust the digital
offset ( command) to remove some of the FPN.
sdo
•
Ensure camera is operating at its expected analog gain,
integration time, and temperature.
•
To save PRNU coefficients after calibration, use the
wpc command.
ccf, cpa
Sets an individual pixel's PRNU coefficient.
spc i1 i2
i1
The pixel number from 1 to n, where n = 2048 or 4096
depending on the resolution.
i2
Coefficient value in a range from 0 to 61438 where:

Before sending this command, use the scl command to select the
color you want to adjust.

Sets a range of pixel PRNU coefficients.
spr i1 i2 i3
i1
The first pixel number of the range.
