Abstract: A color filter array includes a basic array pattern P1 constituted by a square array pattern corresponding to 3×3 pixels. In the color filter array, basic array pattern P1 is arranged in a horizontal direction and a vertical direction repeatedly. G filters that are brightness system pixels are arranged at the four corners and the center, that is, arranged on the both diagonal lines. The G filters are in each line of horizontal, vertical, and diagonal directions of the color filter array, and the color filter array includes a square array that corresponds to 2×2 pixels that are constituted by the G filters. A ratio of the number of G pixels that help most to obtain a brightness signal of the basic array pattern P1 is greater than each ratio of the number of R pixels and the number of B pixels that correspond to the color other than G.

Abstract: Two kinds of color images, obtained by a solid-state imaging device, having different color tones are combined with each other. A first captured color image due to a first pixel group (pixels in which spectral sensitivities of color filters are wide) of the solid-state imaging device is processed. A second captured color image due to a second pixel group (pixels in which spectral sensitivities of color filters are narrow) is processed. The level difference between captured image signals of the pixels of the first pixel group and captured image signals of the pixels of the second pixel group, and due to the spectral sensitivity difference between the color filters in which the spectral sensitivities are wide and narrow is obtained (steps S1 and S2). The level difference is corrected. The first captured color image and the second captured color image are combined with each other.

Abstract: The imaging element has a first and a second phase difference pixel region each including the plurality of phase difference pixels, and an imaging pixel region between the first and the second phase difference pixel region in the first direction. The processor is configured to cause the imaging element to perform imaging at a frame cycle, execute first readout processing of reading out a signal from the first phase difference pixel region during a first frame period, and execute second readout processing of reading out a signal from the second phase difference pixel region during a second frame period subsequent to the first frame period. A first exposure time, during which the first phase difference pixel region is exposed, and a second exposure time, during which the second phase difference pixel region is exposed, are different from an exposure time of the imaging pixel region.
