发明名称 Photometering device for obtaining exposure information
摘要 A multi-metering device comprises division of an object field into a plurality of areas and metering said plurality of areas and generating a plurality of photoelectric outputs corresponding to said plurality of areas, a binary circuit for standardizing said plurality of photoelectric outputs by the average output of said plurality of photoelectric outputs, and a classifying circuit for classifying the object field on the basis of said standardized outputs and operating and extracting a proper metering output by the classifying output.
