An image capturing apparatus includes: a first detection unit that, based on feature amounts of an image obtained by an image sensor, detects a position of a certain subject in the image and a position of a certain part of the certain subject; and a second detection unit that detects a position of a region of the certain subject in the image obtained by the image sensor with a smaller calculation amount than the first detection unit. A focus detection area corresponding to the certain part is selected from among a plurality of focus detection areas based on a relationship between the position of the region of the certain subject detected by the second detection unit and the positions of the certain subject and the certain part detected by the first detection unit.
