COLOR IMAGING ELEMENT AND IMAGING APPARATUS

摘要

A color imaging element, includes a color filter array, in which the color filter array includes an array pattern of a 3×3 pixel group in which first filters corresponding to a green color and second filters corresponding to red and blue colors 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 horizontal and vertical directions, 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 in entire components of one direction among components in the horizontal direction and components in the vertical direction in the pixel group.

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, 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 in entire components of one direction among components in the horizontal direction and components in the vertical direction in the pixel group.
