Abstract:
1. A solid-state image-capture element comprising: a pair of a first phase difference detection pixel, which receives one of a pair of light beams passing through iris regions of different positions of an imaging optical system, a second phase difference detection pixel, which receives the other of the pair of light beams; at least one first phase difference detection area in which a first line and a second line are arranged in the direction orthogonal to the phase difference detection direction; wherein the first phase difference detection pixel and the second phase difference detection pixel are alternately arranged in the phase difference detection direction on the first line; and wherein the first phase difference detection pixel and the second phase difference detection pixel are alternately arranged in the phase difference detection direction on the second line, wherein the first phase difference detection pixel and the second phase difference detection pixel configuring the pair are arranged in a direction intersecting with a phase difference detection direction, wherein the pair comprises a plurality of first pairs and a plurality of second pairs in which a positional relation of the first phase difference detection pixel and the second phase difference detection pixel in each of the first pairs is reverse to each of the second pairs, wherein the first pairs and the second pairs are alternately arranged in the phase difference detection direction, wherein in the first phase difference detection area, the second phase difference detection pixel included on the second line is located in the direction intersecting with the phase difference detection direction as regards the first phase difference detection pixel included on the first line and the first phase difference detection pixel included on the second line is located in the intersecting direction as regards the second phase difference detection pixel included on the first line, wherein the first pair is configured by the first phase difference detection pixel on the first line in the first phase difference detection area and the second phase difference detection pixel on the second line located in the intersecting direction as regards the first phase difference detection pixel, and wherein the second pair is configured by the second phase difference detection pixel on the first line in the first phase difference detection area and the first phase difference detection pixel on the second line located in the intersecting direction as regards the second phase difference detection pixel.
