专利汇可以提供Automatic dimming device of strobe专利检索,专利查询,专利分析的服务。并且PURPOSE:To set a photometric sensitivity distribution to averages light measuring and to make photometry where exposure is matched to only a main object in an optional film surface area possible by using the output of a photodetector, which is controlled variably by an output varying means, as photometric data to control the quantity of emitted light of a strobe. CONSTITUTION:A movable reflective mirror 32 is jumped up and is evacuated from a photographic optical path at a strobe automatic dimming time. Thereafter, a focal plane shutter 36 is opened to its full width, and a strobe 38 starts light emission by turning-on. The strobe reflected light from the object strikes a film 37 to expose the film, and simultaneously, a partial diffused and transmitted light of this reflected light is measured by plural photodetectors 50 arranged in a film pressure plate. Circuits of these photodetectors 50 are connected by a substrate 70 on the rear face, and photometric outputs from plural photodetectors 50 are operated, and light emission stop signal is outputted when a correct exposure is discriminated, thus terminating automatic dimming.,下面是Automatic dimming device of strobe专利的具体信息内容。
