PROBLEM TO BE SOLVED: To provide an image pickup apparatus that is capable of surely focusing on a subject intended by a user, even in such a case that focus adjustment of a contrast detection system is performed with a single-lens reflex camera, and that has satisfactory operability. SOLUTION: When a semi-autofocus mode is selected, a focus lens 102 is driven following the rotating operation of a focus ring 201. At this time, an evaluation value for evaluating contrast in each focus adjustment area is calculated every predetermined period of time. Based on the evaluation value, the peak of the contrast is detected. When the peak of the contrast is detected, focus adjustment for the focus lens 102 corresponding to the focus adjustment area is performed. COPYRIGHT: (C)2009,JPO&INPIT |
