Colorcorrectionmatrix - Toshiba BU505MCG Instruction Manual

ColorCorrectionMatrix

This section describes ColorCorrectionMatrix control of AnalogControl category for the BU series.
This control corrects RGB data by using color correction matrix.
This function is available only in Color models.
The relationship between original data (R, G, and B) and corrected data (R', G', and B') are represented in
the following formula.
