3.9 Camera Selection Variables

There are some camera condition variables that you should determine before adjusting
any digital or analog settings like gain or offset or before changing the camera's
exposure time. These variables are:
the color (or colors) that you want to adjust
the set number where you want to save any of these adjustments
the region of interest for performing these adjustments
Setting the Color Variable

Syntax Elements:
DALSA
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
