Abstract
A color image sensor comprises normal pixels and phase difference pixels. A pixel combining circuit combines pixel signals of the normal pixels, and combines pixel signals of the normal pixel and the phase difference pixel of the same color. Thereby the pixel combining circuit produces a composite image. An edge detector uses a pixel signal of each pixel in the composite image to detect an edge of a subject. The edge is vertical to a direction in which a difference between the pixel signals is at the maximum. A pixel signal correction processor corrects the combined pixel signals through interpolation along the edge and with the use of pixel signals of the same color obtained by combining the pixel signals of the normal pixels in a case where the pixel signals of the phase difference pixels are combined across the edge.
