An image processing method and apparatus for block-based corresponding-point extraction with high-precision, even if an image includes a discontinuous portion. The method comprises an extraction step of extracting edges or outline of a plurality of images, a dividing step of dividing the images into a plurality of blocks in such a manner that every block contains no edge and the sides of every block do not intersect with an edge, and a corresponding-point determination step of determining corresponding points between the images, based on similarity between one block of one image and a corresponding block of another image. Thus, even if one of the images includes a discontinuous portion, the corresponding-point extraction can be smoothly performed.
