Apparatus includes unit configured to compute parallax search range in (x-y-d) three-dimensional space formed of three variables (x and y providing first point (x, y) on first image and parallax candidate d), similarity unit configured to compute degree-of-similarity C (x, y, d) between point (x, y) and second point (x′, y′) corresponding to point (x, y), using sum of products of brightness levels of corresponding pixel pairs between first window on first image and second window on second image, first window including first point (x, y) second window including second point (x′, y′) and unit configured to compute parallax D between first point (x, y) and second point (x′, y′), based on C (x, y, d), where similarity unit includes unit configured to store sum, which is used for computing C (x, y, d) between new first point on first image and new second point on second image.
