Where a point corresponding to a point of interest Pis not detected and a depth value thereof is not known and where points corresponding to surrounding points Pi and Pj are detected and depth values of the points Pi and Pj are known, a depth value of the point of interest Pis determined by interpolation. A provisional corresponding point is determined from the provisional depth value. Region-based search is executed in the neighborhood of the provisional corresponding point so that precision in identifying the location of the corresponding point is improved.
