Patent ID: 8026975

Claim:
An image capturing apparatus for driving a focus lens based on an AF evaluation value obtained from a captured image to carry out autofocus control, comprising: a detection unit which detects a particular object from a captured image; a setting unit which set a focus detection area for the image; a generating unit which generates an AF evaluation value based on a component in a predetermined frequency band contained in the focus detection area of the image; and a control unit which drives the focus lens based on the AF evaluation value, wherein the setting unit sets the focus detection area for a region of the particular object in a case in which the particular object is detected by the detection unit, and sets the focus detection area for a region in a predetermined position and of a predetermined size in a case in which the particular object is not detected by the detection unit, and wherein, in a case in which the focus detection area is set in the region of the particular object, the generating unit generates the AF evaluation value based on a component in a frequency band with the highest frequency lower than in a case in which the focus detection area is set in the region in the predetermined position and of the predetermined size.
