Abstract
An image capture apparatus that detects, from an image, a subject area and a characteristic area within the subject area is disclosed. The image capture apparatus sets an AF area to the characteristic area and detects a defocus amount for the AF area and defocus amounts for peripheral areas of the AF area. The image capture apparatus corrects the defocus amount detected for the AF area based on the defocus amounts detected for the peripheral areas and adjusts focus of an imaging optical system based on the corrected defocus amount.
