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.

scc Co C1 C2 C3
Co = offset (0 to 4095)
C1 = red multiplier (-8192 to +8191)
C2 = green multiplier (-8192 to +8191)
C3 = blue multiplier (-8192 to +8191)
Set coefficients used to combine three color streams, e.g.
White = C + (C x Red) + (C
0 1
C is a DN, whereas:
0
Coefficient = C / 4,096
1-3
Modified by set color command (SCL):
RGB: White
R|G|B: Red, Green, or Blue
All colors are not necessary because constructing white is
different
Factory (initial) values combine the three colors equally:
White = 0 + (0.33 x Red) + (0.33 x Green) + (0.33 x Blue)
C = 0.33 x 4,096= 1,365
n
Red = 0 + (1 x Red) + (0 x Green) + (0 x Blue)
C = 1 x 4,096= 4,096
1
Range of {-8,192 to +8,191} is equivalent to floating point
coefficients of {-2.0 to +1.999}
Step size is 0.000244
Values are saved with camera settings
Values may be viewed with GCP or GET SCC
White = 100 + (0.25 x Red) + (-0.15 x Green) + (0.8 x Blue)
Therefore,
C1 = 0.25 x 4096 = 1024
C2 = (-0.15 x 4096) = -614
C3 = 0.8 x 4096 = 3276
