Abstract

An information processing apparatus for processing stereo images of an object includes a disparity calculator to calculate a disparity of the stereo images. The disparity calculator includes an evaluation value calculator to calculate a correlation evaluation value in a search range set for the stereo images; an extreme value detector to detect an extreme value of the correlation evaluation value; a threshold setting unit to set a threshold range for the detected extreme value; a counting unit to count the number of the extreme value existing within the threshold range; and an updating unit to update the set threshold range to a new threshold range when a new extreme value indicating a higher correlation level of the disparity compared to the set threshold range is detected. The counting unit counts the number of the extreme value in a threshold range updated most recently in the search range.
