Abstract

An image pickup apparatus controls in such a manner that if a touch applied to a touch operation member is detected by a detection unit arranged to detect a touch operation applied to the touch operation member, a photographic preparation unit makes an adjustment of a photographic setting, and after the touch, if the detection unit detects a predetermined touch operation and thereafter detects that the touch operation member loses the touch applied thereto, a photographic processing unit does not execute a photographic processing, while after the touch, if the detection unit detects that the touch operation member loses the touch applied thereto without detecting the predetermined touch operation, the photographic processing unit executes the photographic processing.
