Abstract: An imaging element includes a reading circuit that reads out pixel data obtained by imaging a subject at a first frame rate, a memory that stores the read pixel data, and an output circuit that outputs image data based on the stored pixel data at a second frame rate. The first frame rate is a frame rate higher than the second frame rate. The pixel data includes phase difference pixel data and non-phase difference pixel data different from the phase difference pixel data. The reading circuit reads out the pixel data of each of a plurality of frames in parallel within an output period defined by the second frame rate as a period in which the image data of one frame is output, and performs reading of the non-phase difference pixel data and a plurality of reading of the phase difference pixel data within the output period.

Abstract: Provided are an image capture device and a focus control method capable of performing auto-focus (AF) at high speed by reducing time until a focus control is completed even when a focus control based on a phase difference AF method and a focus control based on a contrast AF method are used in combination. A digital camera performs a correlation operation of two images captured by a pixel pair P1, performs a correlation operation of two images captured by a pixel pair P2, and determines reliability of correlation operation results based on information generated from the two correlation operation results. When the reliability is low, the digital camera performs the contrast AF. Here, the digital camera variably controls a movement step (arbitrary distance) when moving a focus lens in a predetermined range to calculate a contrast value, according to the height of the reliability.
