Abstract:
Photographing at a fixed focus is executed by quickly canceling the autofocus without any labor for mode switching or the like. An image sensing apparatus includes a photographing unit (11, 12, 13) which has an autofocus function and photographs an object image, a key input unit (30) including a shutter key (9) which has two operation strokes and designates autofocus and autoexposure by operation of the first stroke and photographing by operation of the second stroke, and a focus control unit (227) which automatically sets a correct exposure value in the photographing unit (11, 12, 13), detects predetermined operation states of the first and second strokes designated by the shutter key (9), and switches and selects, on the basis of the detection result, whether to operate the autofocus function or set a fixed focus position at which a predetermined depth of field is obtained.
Abstract:
When a hand shake reducing mode has been set for shooting a subject, an exposure is controlled in accordance with a program diagram (solid line) B for the shake reducing mode, which is different from a program diagram (broken line) A for a normal mode. In a state where a shutter speed is set to less than "1/80", two-pixel addition and/or four-pixel addition is executed on an imaging signal to amplify subject luminance, raising ISO sensitivity. A shutter speed set to fall in a high speed range reduces deterioration in image quality due to hand shake and/or subject movement during a shooting operation.
Abstract:
A camera device comprises an optical system including a focus lens, focus control means for focusing the optical system on a subject by driving the focus lens, and display control means for causing the display means to display numerals indicating a first distance of a close end and a second distance of a remote end of a subject distance range in which the focus control means can focus the optical system.
