An original image pattern from image pick-up unit 6, e.g. a TV camera is stored in a first memory 19. An altered image pattern is made from this original image pattern by performing a converting process, such as enlargement, reduction or the like and/or a correcting process by means of a console 10 and a CPU 18. The altered image pattern is stored in a second memory 20. The original image pattern and the altered image pattern are displayed on a CRT 14, either side-by-side or overlappingly in different colours, so that they can be compared. Picture elements may be corrected either singly or in groups (see Figures 4, 8, 9). Corrected image patterns are written into a PROM by prom writer 16 to form a character font, preferably of Chinese characters. <IMAGE> |
