Piranha Color Camera 38
 CCF: calibrate FPN

CCP: calibrate PRNU

CPA: calibrate analog gain (SAG) and PRNU
PRNU calibration includes the FPN whether it is enabled or not (as they are linked). If
you do not want the PRNU calibration to include the effect of FPN then it should be
zeroed first using the RPC command.
CCG 3 (system gain) only includes FPN and PRNU if they are enabled with EPC.
Note: Refer to section 3.9 Camera Selection Variables for details on commands that
should be set before performing any analog or digital adjustments.
3.14 Analog Gain and Analog Offset
All analog signal processing chain commands should be performed prior to FPN and
PRNU calibration and prior to digital signal processing commands.
Setting Analog Gain
Purpose: Sets the camera’s analog gain value. Analog gain is multiplied by
the analog signal to increase the signal strength before the A/D
conversion. It is used to take advantage of the full dynamic
range of the A/D converter.
Syntax: sag t f
Syntax Elements: t
Tap selection. Use 0 for all taps. Color selection limits the
taps that may be selected by this command. See
scl
for
further information.
f
Gain value in a range from
– 10
to
+10
dB.
Notes: To return the current analog gain setting, use the command
gcp
or get sag .
Example: sag 0 5.2
Related Commands: ccg
Calibrating Camera Gain
Purpose: Instead of manually setting the analog gain to a specific value, the camera can
determine appropriate gain values. This command calculates and sets the analog
gain according to the algorithm determined by the first parameter.

i
Calibration algorithm to use.
1 = This algorithm adjusts analog gain so that 8% to 13% of tap region of
interest (ROI) pixels are above the specified target value.
