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:
wpc
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
.
