Abstract

When a color-filter-array of a color-imaging-element is a Bayer-array, outputs of pixels prior to color-mixture correction are acquired from the color imaging element when red light is incident onto the color-imaging-element through a photography optical system, the outputs of the green pixels adjacent to the red pixels, among the acquired outputs of each pixel, are regarded as components of color mixture caused by the red pixels, and ratios of color mixture are calculated. In a central portion of an imaging surface of the color-imaging-element, ratios of color mixture, which do not depend on directions of the color mixture caused by the red pixels, are calculated. In end portions of the imaging surface of the color-imaging-element, separate ratios of color mixture according to the directions of the color mixture caused by the red pixels are respectively calculated. The calculated ratios of color mixture are subjected to interpolation calculation.
