ABSTRACT:
An image-correspondence position detection device comprising an extractor12for extracting a sampling image of specific size from a pair of images, correlation calculator114for generating a correlation value line and calculating an integer correlation position and a decimal correlation position while sequentially shifting the extraction position, measured correlation value calculator118for calculating a measured correlation value for a partial area at the integer correlation position, estimated correlation value calculator116for calculating an estimated correlation value assuming uniform shifting in each pixel of similar sampling images by the difference between the integer correlation position and the decimal correlation position for the partial area, and a correspondence degree calculator120for calculating the degree of correspondence between pixels in the partial area from the measured correlation value and the estimated correlation value.
