Notes: PRNU correction can only be performed in exposure mode
sem 2, sem 9 or sem 10.
Calibrate FPN before calibrating PRNU. If you are not
performing FPN calibration then issue the rpc (reset pixel
coefficients) command and set the sdo (set digital offset)
value so that the output is near zero under dark.
The cpa 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
PRNU calibration. An error message is returned if you attempt
to perform PRNU calibration when using csn 0.
Example:
• cpa 2 700
Calibrating Individual Pixels
Purpose: Sets an individual pixel’s PRNU coefficient.
Syntax
• spc 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 where
PRNU coeff = 1 + (
256
i
)
Notes: The
spc 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
PRNU calibration. An error message is returned if you
attempt to perform PRNU calibration when using
csn 0. To
return the current
csn number, send the command get csn.
Example:
• spc 10 50 200
