Digital photographing apparatus with focus detector comprising a phase difference detector

Abstract

A digital photographing apparatus includes: an image pickup lens; an image pickup device that generates an image signal; an iris that controls an amount of the light transmitted through the image pickup lens; a shutter that controls exposure; a focus detector that detects focus using light transmitted through a predetermined exit pupil region of the lens; and a timing unit that controls a time for closing and/or opening the shutter, when the image pickup device outputs image information, where regardless of the time for closing and/or opening the shutter, the focus detector detects a focus when the iris has an iris value for ensuring transmission of a light flux used to detect the focus, after the exposure is finished. To precisely perform auto focus (AF), the digital photographing apparatus performs continuous AF or simultaneously displays a live view in consideration of timing for adjusting the iris and timing for controlling the shutter.
