Abstract
PURPOSE:To more properly execute the exposure of a main object by controlling the light emission timing of a flash light device in the timing that a diaphragm becomes under by specified stages as compared with the timing which follows the rule of a usual guide number (GN) in the case of daylight synchro-flash photography. CONSTITUTION:A daylight synchro-flash control circuit 3 automatically controls a flash light device by a photometry circuit 2 in case of photographing with rear light. And a GN light emission control circuit 4 automatically controls the flash light device according to the rule of GN when it is detected by the photometry circuit 2 that it is an object with low luminance. Moreover, a manual light emission control circuit 5 forcedly actuates the flash light device by a switch Sw3 which is actuated by interlocking with the external operational button of a lens shutter camera so as to execute the photographing with flash light. An automatic exposure control circuit 6 controls well-known exposure control sequence after a half-push switch Sw1 and a release switch Sw2 are sequentially turned on by the operation of the release button of a lens shutter camera. Thus, the main object can be photographed with proper exposure.
