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.
Syntax
• sfc x y i
Syntax Elements:
• x
The pixel column number from 1 to 1400.
• y
The pixel row number from 1 to 1024.
• i
Coefficient value in a range from 0 to 255.
Notes: The sfc command is not available when the camera is using
the factory calibrated coefficients (csn 0). You must select
