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

Abstract: An image forming apparatus includes an image data memory for storing image data, a temporary memory for two-dimensionally mapping and temporarily storing the image data stored in the image data memory, an image data selecting section for selecting image data from among the image data stored in the temporary memory, an image data enlarging/reducing section for enlarging or reducing the selected image data, an enlarged/reduced image data memory for two-dimensionally mapping and temporarily storing the enlarged or reduced image data, a graphic data memory for storing graphic data to be displayed on a CRT together with the image data, a data synthesizing section for selecting graphic data to be displayed from among graphic data stored in the graphic data memory and synthesizing them and the image data stored in the enlarged/reduced image data memory, a synthesized data memory for two-dimensionally mapping and temporarily storing the synthesized image data and graphic data, a data area selecting section for select
