Serial Interface: How to Control the Camera 57
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
