Claim Text:
1. A distance measurement apparatus that calculates distance information based at least on a first image and a second image, the distance measurement apparatus comprising: a first calculation unit configured to calculate, for each pixel to which distance calculation is performed, distance information corresponding to the pixel on the basis of a local area of a number of local areas in the first image, including the pixel, and a local area of a number of local areas in the second image, corresponding to the local area in the first image; a second calculation unit configured to calculate a non-similarity value between the local area in the first image and the local area in the second image; a determination unit configured to determine whether the non-similarity value is equal to or greater than a threshold; and a third calculation unit configured to calculate a ratio of the number of local areas for which the non-similarity value is determined to be equal to or greater than the threshold in a predetermined area to the number of local areas in the predetermined area.
