ABSTRACT:
Two images to be registered are divided into a plurality of image portions. A standard point for the registration is extracted for each of the image portions divided. Coordinate transformations between two images for the registration are conducted for each image portion by using the standard point extracted. The coordinate values transformed between the image portions are smoothed in the case that they discretely change so that they may be smoothly connected.
