Abstract:
An image processing apparatus for measuring a distance to an object by using a plurality of images of the same photographed object, said image processing apparatus comprising:first extraction means for extracting, from a first reference image, a first candidate pixel which is a candidate for a first corresponding pixel corresponding to a desired pixel on a standard image, for each distance in a first group of distances formed of a plurality of distances which are set discretely in a measurement range; second extraction means for extracting, from a second reference image, a second candidate pixel which is a candidate for a second corresponding pixel corresponding to a desired pixel on the standard image, for each distance in a second group of distances formed of a plurality of distances, different from those of the first group of distances, which are set discretely in a measurement range; computation means for measuring a similarity between the desired pixel on said standard image and the first candidate pixel on said first reference image, and a similarity between the desired pixel on said standard image and the second candidate pixel on said second reference image; and determination means for determining the distance to said object on the basis of the result computed by said computation means.
