2次元適応型YC分離フィルタの開発

概要

論文の詳細を見る
It is known that 2-dimensional adaptive YC separation filter detects correlation of picture and choses optimum filter. This filter improves crossluminance at noncorrelative part of chrominance. But if wrong detection is given on correlation, it causes crosscolour and makes worse picture quality. We have realized accurate judgement being suitable for the sense of sight by inordinate comparison of noncorrelation energy and developed LSI. This paper mainly describes algorizm of correlative judgement.
