ABSTRACT:
A distance measuring device is arranged to emit spot-shaped light toward a subject and receive light reflected from the subject by means of a light receiving sensor having a plurality of light receiving areas, thereby measuring the distance to the subject. In the distance measuring device, among the plurality of light receiving areas, a peripheral light receiving area is selected to be larger than a central light receiving area so that the accuracy of distance measurement is improved.
