ABSTRACT:
A color separation circuit arrangment for separating color components from an image sensor that outputs two kinds of photoelectric conversion signals with different color components for each horizontal scanning line. Color separation is carried out by causing color separation arithmetic means to perform color separation by supplying the arithmetic means with two kinds of photoelectric conversion signals for read unit regions that are formed adjacently on the same horizontal scanning line, output by the image sensors. The color separation apparatus includes signal averaging means for evaluating the average of a plurality of photoelectric conversion signals of at least one kind out of the two kinds of photoelectric conversion signals from the read unit regions provided adjacently on the same horizontal scanning line, and supplying the result of the evaluation to the color separation arithmetic means.
