Abstract

PURPOSE:To increase the degree of freedom of photographing by enabling adequate exposure control by exercising aperture and exposure control on the basis of the stationary light and the quantity of reflected light from a subject. CONSTITUTION:A controller is equipped with a photometric circuit 3 for stationary light, a device 5 for setting photographic speed, a device 2 which outputs a signal of exposure time, devices 1, 6 and 7 which output signals of aperture values, and a processor 8. On the basis of the output signals from the respective devices 1-7, the processor 8 calculates the quantity of reflected light from a subject through the light emission of a flash emitting device for adequate exposure, the aperture value and the exposure time. The signal of the quantity of reflected light from the processor 8 is A/D-converted 9 and the resulting signal is supplied to the flash emitting device. As a result, aperture and exposure control is exercised on the basis of the stationary light and the quantity of the reflected light from the subject.
