ABSTRACT:
By using a result of a detection of an object such as a face, stable focus adjustment of the object can be performed with accuracy. Even if an area that includes the object is not detected, if a tilt of an imaging apparatus is not changed, or a panning or a tilting operation is not detected, a focus detection area, which is used when the object is detected, is maintained.
