Abstract
An automatic exposure control camera adjusts automatically the lens aperture in accordance with information on shutter speed determined in accordance with the brightness of an object or shutter speed set in accordance with manual setting from outside and information on the brightness of the object. The camera controls automatically the shutter speed in accordance with the information on the adjusted aperture value and the information on the brightness of the object. The camera can display a shutter speed value to which a preset shutter speed is automatically corrected when a proper exposure is not obtained even if the aperture is a fully open aperture.
