Television display system |
摘要 |
To provide improved resolution of a television, e.g. CRT, display with reduced large-area flicker, twittering of horizontal edges, and line structure of the picture, the field rate is doubled and the number of lines per field is doubled from that of a received input television signal. Preferably a 21/2 field store arranged in half-field units is used, together with a four-line store arranged in one line units to provide line interpolation, which can be adaptively dependent upon the presence or absence of motion.
