ABSTRACT:
A solid-state imaging apparatus having color separation filters is provided which produces a signal with reduced chrominance and luminance moire and thereby improves resolution, and the spectral characteristics of the color filters for the solid-state imaging apparatus are so set that when the spectral characteristic of each color filter is multiplied by a prescribed coefficient, the sum of four or two horizontally adjacent pixels becomes approximately equal between two vertically adjacent lines. A coefficient multiplying circuit multiplies an output signal from each color filter by the prescribed coefficient, and signal processing is performed.
