An acquisition unit is configured to acquire first defocus information based on a sensor output corresponding to a first region in an area of a captured image, and to acquire second defocus information based on a sensor output corresponding to a second region in the area. A control unit is configured to obtain defocus information corresponding to the area using the first defocus information and the second defocus information, and to perform focus control based on the obtained defocus information. The first region has a length longer in a phase-difference detection direction than the length of the second region.
