Abstract:
A photometry device for a camera, comprising:a normal light sensor that has spectral sensitivity characteristics close to visual sensitivity characteristics, said normal light sensor having a light metering surface divided into a plurality of photometry areas; a plurality of colorimetric sensors that have spectral sensitivity characteristics different from each other; an exposure amount determining system that determines an exposure amount of an object in accordance with an output signal of said normal light sensor; a colorimetry system that determines a color of the object in accordance with output signals of said plurality of colorimetric sensors; and a compensation amount determining system that determines an exposure compensation amount in accordance with the color determined by said colorimetry system, said compensation amount determining system obtaining a difference between a maximum output and a minimum output of the outputs of said plurality of photometry areas of said normal light sensor as a contrast value, said exposure compensation amount being compensated in accordance with the contrast value, wherein said compensation amount determining system compensates for the exposure compensation amount in accordance with output differences among said plurality of colorimetric sensors.
