Mit einer Linse versehene fotografische Filmeinheit und elektronisches Blitzgerät

摘要

A lens-fitted photo film unit includes a flash emitter (9) for emitting flash light toward a photographic object in flash photography. A flash amount control circuit (55, 80) quenches flash emission of the flash emitter when a value of integration of light reflected by the object as measured by a first sensor (27) in the flash photography comes up to a predetermined level. An aperture stop device (18a, 28, 28a, 73, 76, 79) designates one of a large aperture state and a small aperture state. A switch (57) disables the flash amount control circuit if the small aperture state is designated, and enables the flash amount control circuit if the large aperture state is designated. The switch regulates operation of the flash amount control circuit in order to raise an amount of the flash light at a time of the flash photography in the small aperture state.
