Camera Calibration
An example on how to use the color matrix
After calibrating the camera and reviewing the output, you determine that you need to
increase and add more green to your red output. The color matrix commands are found in
the
Analog Controls
set of parameters.
The registers
Color Correction Input Channel (Red, Green, Blue)
and
Color
Correction Output Channel (Red, Green, Blue)
are used to choose locations in the
table: Color CorrectionInput Channel specifies the input channel and Color Correction
Output Channel specifies the output channel. The
Color Correction Value
(in a range
-
32000 to 32000
) parameter specifies the correction coefficient.
Starting with the default values:
Ending with an increase of red and green in the red output.
