In a second image sensor 200 which has a plurality of phase difference detection pixels which generate signals for performing adjusted focus decision by way of phase difference detection and a plurality of image generation pixels which generate signals for generating images, a first pixel group which is formed by arranging part of phase difference detection pixels of the plurality of phase difference detection pixels in a specific direction, and a second pixel group which is formed by arranging part of image generation pixels of the plurality of image generation pixels in the specific direction are alternately arranged in an orthogonal direction orthogonal to the specific direction. Consequently, when an image capture element used to detect a phase difference and generate an image generates an image, it is possible to reduce a load of processing related to image generation.
