ABSTRACT:
To accurately and easily measure distance even when a photographic subject image has contrast portions inclined at various angles, a shift quantity, between a pair of left and right photographic subject images formed by a pair of left and right optical distance measuring systems having a base length, is detected and then a distance up to the photographic subject is measured. Also, the distance measuring device comprises a plurality of upper and lower photoelectric conversion element arrays arranged with respect to a pair of photographic subject images for detecting a pair of photographic subject images of the same portion of the photographic subject, an image information generating section for generating image information in the same direction as an image shift direction of the photographic subject image of the same portion of the photographic subject by processing left image information and right image information converted photoelectrically by the plurality of upper and lower photoelectric conversion element arrays, and an image shift quantity detecting section for detecting a shift quantity of the photographic subject image of the same portion of the photographic subject, based on a pair of left image information and right image information generated. Based on the detected shift quantity, a distance up to the photographic subject is measured.
