field flicker
解釋
區閃爍-
Employing the interlaced scanning, current tv system can compress the frequency band of tv signal effectively and facilitate transmission. but this method reduces the scanning lines of pictures and the frequency of the field. it leads the pictures displayed on tv to have such disadvantages as large area flicker, edge flicker, interlace flicker, raster visibility and creeping line etc. to satisfy people " s vision feeling better, the big - screen, multi - function and high quality tv - set have been made great progress
現行的廣播電視系統由於採用隔行掃描方式，從而有效地壓縮了電視信號的頻帶，有利於傳輸；但由於這種方式使得圖像的掃描行數少，場頻低，導致了重顯的電視圖像有大面積閃爍、邊緣閃爍、行間閃爍、行結構可見及行爬行等。 -
In the dissertation, the author uses objective and subjective measurement respectively to compare among philips ' s 1st ( c ' s algorithm, philips ' s 2nd ic ' s algorithm and our own motion compensated algorithm. simulation shows our algorithm solves the problem of horizontal edge flicker in saa4991, alleviates the problem of " tear " in saa4992. the author also uses subjective measurement to compare among our edge - based motion adaptive de - interlacing algorithm, traditional intra - field interpolation algorithm and faroudja ' s dcdi algorithm. simulation shows our own edge - based algorithm can remove the sawtooth on the object ' s edge, and has basically reach the level of dcdi
論文從主觀和客觀兩個角度對比分析了自有的運動補償演算法和飛利浦一代晶元saa4991 、二代晶元saa4992中的運動補償演算法的性能：自有演算法對于圖像的水平邊有效抑制了saa4991存在的閃爍現象，減小了saa4992存在的拖尾問題；自有的邊沿演算法消除了傳統演算法在物體邊沿處存在的鋸齒，可以得到清晰平滑的邊沿，基本達到了dcdi演算法的水平。
