TELEVISION SIGNAL PROCESSING SYSTEM FOR REDUCING DIAGONAL IMAGE ARTIFACTS |
摘要 |
<p>Apparatus is disclosed for reducing unwanted jagged diagonal artifacts in a video signal. At an encoder, apparatus (38) intraframe averages moving image information over a given frequency range, e.g., above 1.4 MHz, while still image information is subjected to a field repeat process over a given frequency range. At a decoder, apparatus (1337) subjects still image information to a frame repeat process over the given field repeat frequency range, while moving image information is left unchanged.</p> |
