Abstract
Color separating characteristics which are preferable in case of obtaining the primary color components are obtained from an image pickup signal by using a color separation matrix. A luminance signal is obtained by a luminance signal formation processing section from the signal supplied from an image pickup device through an A/D converter and chrominance signals are obtained by a chrominance signal separation processing section. In the chrominance signal separation processing section, the signals obtained from the image pickup signal are multiplied with a color separation matrix, thereby obtaining primary color components RGB. The color separation matrix is constructed by coefficients for white balance adjustment and coefficients for adjustment in consideration of the primary color components of the image pickup signal.
