PROBLEM TO BE SOLVED: To calculate stably the distance to an object regardless of the size of the object which is a distance measuring object. SOLUTION: An extraction part 20 uses each input image input successively from a standard camera 110 as a standard image and each input image input successively from a reference camera 120 as a reference image, and extracts an object domain which is a domain where a front vehicle body is photographed from each standard image. An area calculation part 30 calculates the area of the object domain extracted by the extraction part 20. A density setting part 40 heightens a set density of an attention point gradually as the area of the object domain calculated by the area calculation part 30 is reduced. An attention point searching part 50 sets successively each attention point in the object domain extracted by the extraction part 20 according to the set density of the attention point changed by the density setting part 40, and searches for a correspondence point of each attention point from the reference image obtained at the same time as the standard image where the attention point is set.
