Abstract
The present invention discloses a digital camera having a live view mode for continuously capturing and displaying a series of subject images, in which when the live view mode is selected, a computation part initializes an aperture mechanism based on photographing lens-specific information. Since the aperture mechanism is controlled based on the photographing lens-specific information in a live-view initialization process, the possibility of damaging an imager while a photographer is framing a picture can be reduced. The photographing lens-specific information includes, for example, focal length information and maximum aperture value information. The computation part can be configured, for example, to initialize the aperture mechanism in such a manner that the amount of light from the sun per unit area, or the total amount of light from the sun, will always become almost equal regardless of the kind of photographing lens.
