ABSTRACT:
A color signal of a primary color or a color signal of a complementary color is converted from a CCD to signals in a color space having an intensity, a hue and a chroma. Tone conversion is performed on a luminance signal. A chroma correction coefficient is calculated to be used for performing correction on a chroma signal. A first maximum chroma value is calculated with respect to the luminance signal and a hue signal and a second maximum chroma value is calculated with respect to the hue signal and the converted luminance signal. And a correction coefficient is calculated based on the first and second maximum chroma values and the chroma signal is corrected based on the correction coefficient and the chroma correction coefficient.
