Abstract:
1. A digital camera comprising: a photographing device comprising a photographing optical system; a projector device comprising one of an optical system functioning as a projection optical system, that is different from the photographing optical system and a projection optical system that is different from the photographing optical system; a switching member to switch the digital camera between a photographing operation mode in which image data photographed by the photographing device is captured through the photographic optical system and a projection operation mode in which an image is projected by the projector device through the projection optical system; an operation member disposed at a casing of the digital camera; a function adjustment device that controls a function of the operation member to function as (a) an operation member for a photographing operation when the digital camera is in the photographing operation mode and (b) an operation member for a projection operation when the digital camera is in the projection operation mode; a projection control device that controls the projector device based upon operation of the operation member when the digital camera is in the projection operation mode; and a photographing control device controlling the photographing device based upon operation of the operation member when the digital camera is in the photographing operation mode, wherein the operation member includes a shutter release operation member that outputs operation signals each corresponding to a halfway press operation mode or a full press operation mode, the photographing control device controls the photographing device so as to execute photographing processing in correspondence to a signal indicating one of the halfway press operation mode and the full press operation mode provided by the shutter release operation member, and the projection control device issues one of a focus adjustment start instruction, a reproduced image projection instruction, a projection image rotation instruction and a projection pause instruction for the projector device based upon a signal indicating one of the halfway press operation mode and the full press operation mode provided by the shutter release operation member and a length of time over which the signal is sustained.
