Abstract
A photographing device has a range sensor including a plurality of range sensing elements, and a photometric sensor including a plurality of photometric elements. The positions of the photometric elements on the photometric sensor correspond to the positions of the range finding elements on the range sensor. Further, the area of each photometric element is larger than the area of the corresponding range finding element. Thus, proper exposure control may be affected for a selected range finding element.
