A solid-state imaging device having a color filter of a checkered pattern arranged in an all-pixel reading solid-state image sensor includes an original signal aperture compensation means for forming an original signal aperture compensation signal from all pixels of a color filter, a luminance signal aperture compensation means for forming a luminance signal aperture compensation signal from a luminance signal obtained by synthesizing the all pixels of the color filter, and a chrominance signal ratio detecting means for detecting an output ratio of chrominance signals. The original signal aperture compensation signal and the luminance signal aperture compensation signal are weighed in response to a detection output from the chrominance signal ratio detecting means. Thereafter, the weighed original signal aperture compensation signal and the weighed luminance signal aperture compensation signal are added to obtain an aperture compensation signal. <IMAGE> |
