A focus detection apparatus hierarchically detects one or more specific region from an object in a captured image, sets focus detection regions divided into a plurality of regions with respect to the specific region, detects focus detection information for each focus detection region, decides a target region for performing an automatic focus operation, obtains a distribution of defocus amount of the specific region, and changes a range for obtaining a distribution of defocus amount of a lower level region in a case where a distribution of defocus amount of an upper level region is not less than a predetermined range, when deciding the target region included in the upper level region based on the distribution of defocus amount of the lower level region in the specific region.
