Abstract

A corresponding point candidate determiner () determines whether plural correlation peaks appear, based on a correlation value calculated by a corresponding point determiner (). In the case where the corresponding point candidate determiner () determines that plural correlation peaks appear, the corresponding point determiner () calculates a ratio between the correlation values as represented by the correlation peaks, determines one or more corresponding points, based on the calculated ratio, and notifies the determination result to an initial position setter (). In the case where the corresponding point determiner () searches plural corresponding points, the initial position setter () sets an initial search position with respect to each of the corresponding points in a reference image of a layer immediately higher than a target layer.
