ABSTRACT:
A minimum value of input color image signals (R, G, B) is extracted, difference signals between the extracted minimum value and the input signals (R, G, B) are calculated, and matrix conversion is executed based on the difference signals, thereby obtaining desired output color image signals having a color reproduction range different from that of the input color image signals.
