发明名称 Photometry device for a camera including external light sensor
摘要 A photometry device for a camera is provided with a normal light sensor having spectral sensitivity characteristics close to visual sensitivity characteristics, a plurality of colorimetric sensors having spectral sensitivity characteristics that are different from those of the normal light sensor, an exposure amount determining system that determines an exposure amount of an object in accordance with an output of the normal light sensor. A color of the object is determined in accordance with the outputs of the plurality of colorimetric sensors and an external light sensor that measures an external light illuminating the object at spectral sensitivity characteristics corresponding to each of the plurality of colorimetric sensors. Then, based on the determined color, an exposure compensation amount is determined.
