ABSTRACT:
A shade pattern can be added characters or character strings by a simple arrangement. Count values of a vertical direction counter (2) and a horizontal direction counter (3) are supplied to an address signal generator (4), and an address signal from the address signal generator (4) is supplied to a memory, i.e. RAM (5), in which character codes to be displayed, etc., are stored. A character code from the memory (5) is supplied to a memory, i.e. ROM (6) in which character patterns and so on are stored. Count values of a character vertical counter (7) and a character horizontal counter (8) are supplied to the memory (6) which derives a signal representing a character pattern to be displayed. The signal representing the character code or the like from the memory (5), the signal representing character codes to be displayed on peripheral portions and the count values of the counters (7), (8) are supplied to a pattern generator (9) which generates a shade pattern signal. The shade pattern signal and the character pattern signal are supplied to a pattern synthesizer (10) which generates a displaying synthesized pattern signal.
