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 invention, plural pixels constituting a color image pickup device include a first pair of RB pixels and a second pair of RB pixels both constituted by a red pixel R having a red color filter and a blue pixel B having a blue color filter in a horizontal direction A and vertical direction B, the red pixel and the blue pixel being adjacent to each other. A position of the red pixel R and a position of the blue pixel B are opposite to each other between the first pair of RB pixels and the second pair of RB pixels. Pixel data of the blue pixel B of the first pair of RB pixels is compared with pixel data of the blue pixel of the second pair of RB pixels to detect whether or not anomalous oblique incident light is incident on the color image pickup device.

Abstract: The present invention utilizes color mixings with angle dependencies from adjacent R pixels, and in the case where a subject color is red, uses first and second B pixels as phase-difference pixels, allowing for an accurate phase-difference AF based on the output signals of the first and second B pixels. Here, it is unnecessary to provide phase-difference pixels dedicated to the case where the subject color is red, and the phase difference is detected using ordinary B pixels of an imaging element. Therefore, the resolution is not sacrificed.
