An image capturing apparatus senses a subject by an image sensor to acquire image data, detects a face from the image data, estimates a distance from the image sensor to the detected face in a real space, obtains first and second depths of field based on a focal length, an f-number, and the estimated distance/a distance in the real space to an in-focus point when acquiring the image data used to detect the face, calculates a first and second scan ranges based on the first/second depths of field and the estimated distance/the distance to the in-focus point, detects the in-focus point based on a contrast signal acquired while driving the focus lens in the first or second scan range selected by a selection unit, which selects the first scan range if at least part of the first and second scan ranges overlaps, otherwise does not select the first scan range.
