Abstract:
A photometric device includes split photometric sensors for photometrically measuring a plurality of different split regions of a subject image formed by photometric optical systems. The split photometric regions of each split photometric sensor are formed in such a manner as to partially overlap with the split photometric regions of the other split photometric sensor.
