ABSTRACT:
An image processing system has an image processing function for use in, particularly, a word processor, a copying machine, or a facsimile apparatus. This apparatus includes an image reader to read and input image information; a keyboard to input character information; a recognizing unit for recognizing the character information in the image information inputted by the image reader; and an image processor for performing the editing of characters on the basis of the result by the recognizing unit. The character information includes lines of character strings, paragraphs in document information, spaces between words, spaces between characters, hyphens, or positions of words. The image processor means performs the image editing processes such as right alignment, deletion, rewriting, insertion, search, and the like with respect to the character information recognized by the recognizing unit. With this system, the character data inputted from the keyboard and the image data read by the image reader can be processed at the same level, so that the new documents can be freely produced.
