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 2352.
y
The pixel row number from 1 to 1728.
i
Coefficient value in a range from 0 to 12287 where
PRNU multiplier = 1 + (
4096
i
)
Notes:
 The spc command is not available when the camera is using
the factory calibrated coefficients (
csn 0-7). You must select
the user coefficient set (
csn 8-15) before you can perform
PRNU calibration. An error message is returned if you attempt
to perform PRNU calibration when using csn 0-7. To return
the current
csn number, send the command get csn.
Example:
spc 10 50 500
3.7.6 Saving, Loading and Resetting Coefficients
Saving the Current PRNU Coefficients
Purpose: Saves the current PRNU coefficients to non-volatile memory.
Syntax:
wpc
Notes:
 The wpc command is not available when the camera is using the
factory calibrated coefficients (csn 0-7). You must select the
user coefficient set (csn 8-15) before you can perform PRNU
calibration. An error message is returned if you attempt to
perform PRNU calibration when using csn 0-7. To return the
current
csn number, send the command get csn.
Example:

Saving the Current FPN Coefficients
Purpose: Saves the current FPN coefficients to non-volatile memory.
Syntax:
wfc
Notes:
 The wfc command is not available when the camera is using the
factory calibrated coefficients (csn 0-7). You must select the
user coefficient set (csn 8-15) before you can save FPN
coefficients. An error message is returned if you attempt to save
FPN coefficients when using csn 0-7. To return the current
csn number, send the command get csn.
