Solid-state image capture element, image capture device, and focus control method

摘要

A solid-state image capture element includes a pixel, which receives light of one of a pair of light beams which pass through iris regions of different locations on a photographic lens, and a pixel which receives light of the other, in a pair of said pixels. The pair of pixels are positioned shifted from one another in a direction which intersects the x-axis which is the phase difference direction. The pair includes a plurality of first pairs and second pairs which respectively have mutually inverse location relations with respect to the pixels and the pixels therein. The first pair and the second pair are alternately positioned in either the phase difference detection direction or the direction which is orthogonal thereto.
