System for on-screen-display

摘要

In on-screen-display (OSD), characters and graphic images selected by an operator from predetermined characters and graphic images are reproduced on a display (14a) such as a liquid crystal display. A font code memory (24) is provided for storing a font code (Da) of a character or a graphic image input by the operator. A graphic font detector (40) is provided for detecting whether the stored font code is a character font or a graphic font. A font data memory (25) stores a plurality of font data (Dc) for reproducing the predetermined characters and the graphic images. Font data (Dc) read from the font data memory (25) are loaded on shift registers (6A) and applied to the display (14a) in order to reproduce the stored font data. <IMAGE>
