ABSTRACT:
The matrix coefficient determining process of the present invention can determine linear matrix and color-difference matrix coefficients appropriate for a given type of light source at the same time. The coefficients can be used to perform color correction of RAW data to ensure good color reproduction. Furthermore, by performing the matrix coefficient determining process for a number of types of light sources, optimum color reproduction coefficients and for each of the light sources can be obtained.
