Serial Interface: How to Control the Camera 55
Notes: Before performing this command, stop all light from entering
the camera. (Tip: cover lens with a lens cap.)
The goal is to subtract all non-uniformities and offsets to
obtain a 0 DN output in dark. Analog offset should be set to 0
since it gets subtracted out during FPN calibration.
Set the digital gain to 1 x gain (
ssg 0 4096
) since during
calibration it is forced to 1 x gain.
Perform FPN correction before PRNU correction.
The
ccf
command is not available when the camera is using
the factory calibrated coefficients (
csn 0
). You must select
the user coefficient set (
csn 1
) before you can perform FPN
calibration. An error message is returned if you attempt to
perform FPN calibration when using
csn 0
.
If you are operating the camera in test pattern mode (
svm 1
-
8
), you must turn off exposure correction (
eec 0
) prior to
running the
ccf
command.
The LED flashes green while coefficients are computed. After
completion, the LED should return to solid green, unless an
error occurred during calibration.
Example: •
ccf
FPN correction can only be performed in exposure modes
sem 2, sem 9
and
sem 10
.
Calibrating Individual Pixels
Purpose: Sets an individual pixel’s FPN coefficient.
