ABSTRACT:
A document editing apparatus in which image data such as data representing an illustration is converted to total digital image data pertaining to a complete image. The total digital image data is divided into a predetermined number of pieces that each include a predetermined number of dots. The divided digital image data is stored in memory as external character data. The total digital image data is converted into a divided digital character data assembly and registered as a digital character data block in memory. Next, character data representing document data is inputted into the memory. The digital character data block and the character data exist together in memory as coexisting editing data. Since the digital image data exists together with the character data in memory, editing processing of document data including the character data and the digital image data can be carried out at one time during operation processing.
