摘要 |
A photometry device for a camera has a normal light metering system and a plurality of light metering systems having different spectral sensitivity characteristics. An exposure amount of an object is determined in accordance with an output of the normal light metering system. A colorimetry system divides a photometry area into a plurality of areas and judges a color of the object at each of the plurality of areas. The compensation amount determining system determines the exposure compensation amounts respectively corresponding to the plurality of areas based on the color thereat.
