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 selecting a part of a data area stored in the synthesized data memory, a window memory for two-dimensionally mapping and temporarily storing the part of the selected data area, and image displaying section for displaying an image on the CRT based on the data stored in the window memory. According to the thus constituted image forming apparatus, it is possible to form a visible image on the CRT based on image data which can scroll the image formed on the CRT at a high speed.
