Title (EN) FILTERING INTENSITY DECISION METHOD, MOVING PICTURE ENCODING METHOD, AND MOVING PICTURE DECODING METHOD
(FR) METHODE POUR DETERMINER UNE INTENSITE DE FILTRAGE, METHODE D'ENCODAGE D'UNE IMAGE ANIMEE, ET METHODE DE DECODAGE D'UNE IMAGE ANIMEE
(JA) フィルタリング強度の決定方法、動画像符号化方法、および動画像復号化方法
Abstract: front page image
(EN)A moving picture encoding device includes an inter-pixel filter (114) having a filter A (114a), a filter B (114b), a filter C (114c), and a filter D (114d) each having different filtering intensity for filtering decoded image data and removing block distortion which is a high frequency noise in the vicinity of the boundary between blocks, and a filter processing control section (110) for deciding the filtering intensity of the inter-pixel filter (114).
(FR)L'invention concerne un dispositif d'encodage d'images animées, qui comprend un filtre inter-pixels (114) constitué d'un filtre A (114a), d'un filtre B (114b), d'un filtre C (114c) et d'un filtre D (114d). Chaque filtre présente une intensité de filtrage différente permettant de filtrer des données d'image décodées et d'éliminer une distorsion de bloc qui est un bruit haute fréquence présente à proximité de la frontière entre des blocs. Le dispositif d'encodage présente également une section de commande de traitement de filtrage (110) pour déterminer l'intensité de filtrage du filtre inter-pixels (114).
(JA)動画像符号化装置は、復号化画像データをフィルタリングしてブロック間の境界付近における高周波ノイズであるブロック歪みを除去する、それぞれフィルタリング強度が異なるフィルタA(114a)、フィルタB(114b)、フィルタC(114c)、およびフィルタD(114d)を有する画素間フィルタ(114)と、この画素間フィルタ(114)のフィルタリング強度を決定するフィルタ処理制御部(110)を備える。
