ABSTRACT:
A character generator for generating a data signal for a character having an emphasizing contour. The generator includes a memory storing data of a character to be displayed. This data comprising first data representing a contour of the character and second data representing a compressed character data. The first data are stored in a first shift register and shifted in synchronism with a first shift clock, and the second data are stored in a second shift register and shifted in synchronism with a second shift clock having a frequency smaller than that of the first shift clock. A contour signal and a character signal are thereby generated.
