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. |
