Abstract

PURPOSE: To set an arbitrary expansion rate in horizontal and vertical directions with a small storage capacity to improve the performance by constituting a picture memory, where display data corresponding to each character to be displayed on a CRT is stored, of a character code part, a horizontal code part, and a vertical code part. CONSTITUTION: A vertical code part 26, a horizontal code part 25, a raster address conversion memory 22, and a character font data conversion memory 23 are used to expand and display character font data. Consequently, the memory capacity of an entire CRT display device is considerably saved because it is sufficient if only one kind of character font as an original pattern is stored in a character generator 4. Since character expansion can be controlled only by the vertical code part 26 and the horizontal code part 25, picture contents displayed on a CRT 1 can be quickly updated. Thus, a raster scan type CRT display device is realized which has an arbitrary expansion rate set in horizontal and vertical directions with a small storage capacity and is excellent in general usefulness and has a high performance.
