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.

Abstract: In an aspect of the present invention, only by storing the first correction coefficients corresponding to the colors of the color filters of the image pickup element and the second correction coefficients corresponding to the relative positions of the pixels to the position of the specific circuit element of the image pickup element, in the storage device, an adequate combination of the first correction coefficients and the second correction coefficients is selected for each pixel, and a calculation with it is performed with respect to the signal value of each of the pixels. Therefore, with an essential minimum number of correction coefficients, it is possible to quickly and accurately correct the variation in signal values caused by the color array for the color filters of the image pickup element and the variation in signal values caused by the structure in which multiple pixels share the specific circuit element.
