Abstract

A digital single-lens reflex camera comprises: an optical viewfinder; a retractable movable mirror for guiding subject images to the optical viewfinder; an image display device, serving as an electronic viewfinder, for displaying a subject image captured by an image-capturing device with the movable mirror retracted from the optical path; and a control device for starting image data acquisition with the image-capturing device after elapsing of a predetermined time, taking into consideration the amount of time necessary for the movable mirror to be retracted from the optical path and maximum diaphragm driving time of a diaphragm driving unit, following the user making a releasing operation while displaying a moving image on the image display device. This realizes a digital single-lens reflex camera which allows settings wherein the shutter release time lag is constantly the same, regardless of whether the optical viewfinder or the electronic viewfinder is used.

Description

technical field [0001] The present invention relates to a single reflex digital camera, and more particularly to a single reflex digital camera having an electronic viewfinder for displaying moving images based on image data continuously output from an imaging element using a display device. Background technique [0002] At present, a still image photographing device (hereinafter referred to as a digital camera) has practicality and is widely popularized. This photographing device is constituted in such a way that a light beam from an object to be photographed (hereinafter referred to as an object light beam) is incident on a camera composed of a plurality of lenses. In the imaging optical system composed of groups, the formed subject image is imaged at a predetermined position (for example, the light-receiving surface of an imaging element such as a charge-coupled device (CCD, Charge Coupled Device)), thereby obtaining a desired subject image, And record it in a prescribed ...
