なっていることを特徴とするカメラの測光装置。[Claim for Utility Model Registration] After passing through the photographic lens, reflection from the film surface, the shutter curtain surface, the photometric reflector placed in front of the shutter curtain, or the sub-mirror provided behind the semi-transparent reflex mirror, etc. Automatic exposure control is now performed by measuring the light transmitted through the lens reflected by one of the surfaces with a light-receiving element located between the photographing lens and the film surface and away from the photographing light beam. In an automatic exposure control camera, the first light receiving element is arranged below the optical axis of the light beam directed toward the film surface and receives lens transmitted light reflected by any of the reflecting surfaces, and the first light receiving element a pair of second light-receiving elements that are arranged substantially symmetrically on both sides of the film and receive the lens-transmitted light reflected by the film surface, and the first light-receiving element
Automatic exposure control during daytime photography is performed based on the output of the second light-receiving element, and strobe light emission amount control during flash photography is performed based on the output of the second light-receiving element. Camera photometry device.
