Claim Text:
1. A color imaging element in which color filters of a predetermined color filter array are placed on a plurality of pixels constituted by photoelectric conversion elements arrayed in horizontal and vertical directions, wherein the color filter array includes an array pattern of a 3×3 pixel group in which first filters corresponding to a first color that contributes most to acquiring a luminance signal and second filters corresponding to two or more second colors other than the first color are arrayed, and the first filters are placed at a center and 4 corners in the 3×3 pixel group, and the array pattern is repeatedly placed in the horizontal and vertical directions without intervening other pixels, the first filter is placed in a line of each of horizontal, vertical and oblique directions of the color filter array, a proportion of a number of pixels of the first color corresponding to the first filters is larger than a proportion of a number of pixels of each color of the second colors corresponding to the second filters, and in a pixel group within a predetermined area of the color imaging element, phase difference detection pixels for acquiring phase difference information are placed to cover every component of at least one of the horizontal direction and the vertical direction in the pixel group and normal pixels different from the phase difference detection pixels are placed in the pixel group, wherein the first color is green color and the second colors are red color and blue color, an array pattern, in which, among 4 pixels other than the pixels at the center and 4 corners in the 3×3 pixel group, 2 pixels on a same vertical line are set as red color and 2 remaining pixels are set as blue color, is set as a first array, and an array pattern, in which, among 4 pixels, 2 pixels on a same horizontal line are set as red color and 2 remaining pixels are set as blue color, is set as a second array, and the first array and the second array are alternately placed in both the horizontal and vertical directions.
