An image processing apparatus includes a temporary memory for two-dimensionally mapping and temporarily storing image data containing image region data corresponding to two image regions having a similar shape and stored in an image data memory, a CRT for reproducing images based on the image data stored in the temporary memory, an interest region defining section for defining a region of interest in one of the two image regions having a similar shape displayed on the CRT, a pixel specifying section for specifying a first reference pixel in the one of the two image regions having a similar shape and specifying a second pixel corresponding to the first reference pixel in one image region other than the one of two image regions, a copy section for copying the region of interest defined by the interest region defining section and the first reference pixel specified by the pixel specifying section, a template matching section for effecting template matching between minute region image data corresponding to a minute region containing the coordinate value of the first reference pixel as a center coordinate value and minute region image data corresponding to a minute region containing the coordinate value of the second reference pixel corresponding to the first reference pixel as a center coordinate value, and an affine conversion section for effecting an affine conversion on image data corresponding to an outer periphery of the region of interest stored in the temporary memory based on the result of the template. The thus constituted image processing apparatus can easily define image regions corresponding to each other in two images or image regions corresponding to each other in an image as regions of interest using the same figure.
