Performing PRNU Calculation to a Camera Calculated Value
Purpose: Performs PRNU correction and eliminates the difference in
responsivity between the most and least sensitive pixel creating a
uniform response to light.
Syntax
ccp
Notes: •
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
rpc
command to
reset all coefficients to zero, and save them to memory
with the
wfc command. You can then adjust the digital
offset (
sdo
command) to remove some of the FPN.
•
Ensure camera is operating at its expected analog gain,
integration time, and temperature.
•
To save PRNU coefficients after calibration, use the
wpc
command.
