PURPOSE:To decrease the number of times of processing and to execute the picture drawing processing at a high speed by executing the picture drawing processing by developing a pattern to fixed width, in the case a size of length and width of a pattern to be brought to picture drawing is an exact divisor of a picture drawing part. CONSTITUTION:A pattern size deciding part 11 decides whether a size of length and width of a pattern is the same as picture drawing fixed width or an exact divisor. In the case the above size is the same size as the foxed width, a pattern picture drawing part 13 stores the pattern by fixed width each in a display area of a frame memory 2, and displays it on a CRT 4. On the other hand, in the case the above size is an exact divisor of the fixed width, the pattern is developed to the fixed width by a pattern developing part 12, stored in a work area of the frame memory 2, and thereafter, displayed on the CRT 4. |
