7.3.4 Color Transformation
Introduction
The main objective for using a color transformation matrix is to make corrections to the color
information delivered by the camera’s sensor. The correction can account for the kind of light source
used during image acquisition and compensate for imperfections in the sensor’s color generation
process.
Color correction by means of the color transformation matrix is intended for use by
only someone who is thoroughly familiar with matrix color transformations. It is
nearly impossible to enter correct values in the transformation matrix by
trial and error.
For color transformation to work properly, the white balance must be correct.
See Section 7.3.1 on page 160 for more information about the white balance and
see Section 7.3.5 on page 171 for an overall procedure for setting the color
enhancement features.
Although the color transformation matrix can be used without using a light source
preset, we nonetheless strongly recommend to also use the suitable light source
preset if available, to make full use of the camera’s color enhancement
capabilities.
If no suitable light source preset is available you can perform the desired color
corrections using the color transformation matrix.
If color binning is enabled for the acA1920-25uc, the color transformation matrix
will be applied after color binning was performed. For more information about color
binning, see Section 8.6.2 on page 193.
