Abstract:
A photometry device for a camera, comprising:a normal light sensor that has a plurality of photometry areas and performs a photometry operation with respect to an object at each of said plurality of photometry areas, said normal light sensor having a spectral sensitive characteristics close to those of a human eye; a plurality of colorimetric sensors for colorimetry capable of performing photometry with respect to each of said plurality of photometry areas, said plurality of colorimetric sensors having different spectral sensitivity characteristics; a photometry value determining system that determines an photometry value at each of said plurality of photometry areas in accordance with outputs of said normal light sensor corresponding to said plurality of photometry areas; a colorimetric compensation value determining system that determines a color of an object at each of said plurality of photometry areas in accordance with the outputs of said plurality of colorimetric sensors and determining a colorimetric compensation value based on the determined color; and an exposure value determining system that compensates for the photometry value determined by said photometry value determining system for each of said plurality of photometry areas, and determines an exposure value based on the compensated photometry values, wherein said colorimetric compensation value determining system determines different colorimetric compensation values for different one of said plurality of photometry areas.
