7.9 Saving and Restoring PRNU and FPN
Coefficients
Saving the Current PRNU Coefficients
Saving the Current FPN Coefficients
Purpose: Saves the current FPN coefficients. You can save up to four sets of
pixel coefficients
Syntax:
wfc i
Syntax Elements:
i
FPN coefficients set to save.
1 = Coefficient set one
2 = Coefficient set two
3 = Coefficient set three
4 = Coefficient set four
Example:
wfc 2
Loading a Saved Set of Coefficients
Purpose: Loads a saved set of pixel coefficients. A factory calibrated set of
coefficients is available.
Syntax:
lpc i
Syntax Elements:
i
FPN coefficients set to save.
0 = Factory calibrated pixel coefficients.
1 = Coefficient set one
2 = Coefficient set two
3 = Coefficient set three
4 = Coefficient set four
Example:
lpc 0
Resetting the Current Pixel Coefficients
Purpose: Resets the current pixel coefficients to zero. This command does
not reset saved coefficients.
Purpose:
Saves the current PRNU coefficients. You can save up to four sets
of pixel coefficients
Syntax:
wpc i
Syntax Elements:
i
PRNU coefficients set to save.
1 = Coefficient set one
2 = Coefficient set two
3 = Coefficient set three
4 = Coefficient set four
Example:
wpc 2
