发明名称 Photometry device
摘要 A photometry device for a camera is provided with a normal light sensor having a plurality of photometry areas, and a plurality of photometric sensors for colorimetry. A photometry value determining system determines a photometry value at each photometry area in accordance with outputs of the normal light sensor. A colorimetric compensation value determining system determines a color of an object at each photometry area in accordance with the outputs of the photometric sensors for colorimetry, and determines a colorimetric compensation value based on the determined color. An exposure value determining system compensates for the photometry value determined by the photometry value determining system for each o photometry area, and determines an exposure value based on the compensated photometry values. The colorimetric compensation value determining system determines different threshold values, which are used for determining colors at the plurality of photometry areas, for different photometry areas.
