Abstract
An image processing apparatus includes a temporary memory for two-dimensionally mapping and temporarily storing image data containing image data regions corresponding to at least two image regions having similar shape and stored in an image data storing section, a CRT for reproducing an image based on the image data stored in the temporary memory, a pixel specifying section for specifying pixels corresponding to at least two equivalent points in at least two image regions having similar shape in the image displayed on the CRT, a data correcting section for effecting, between micro region image data corresponding to micro regions including coordinates of the at least two pixels specified by the pixel specifying section as center coordinates, rotation and movement correction and enlargement/reduction magnification correction on the micro region image data in the image data corresponding to one image region so that a rotation angle and an enlargement/reduction magnification of the one image region coincide with those of a reference image region which is one of the at least two image regions, a template matching section for effecting template matching on the micro region image data cor…
