Abstract:
(EN) The purpose of the present invention is to limit the overhead of a flag indicating a motion compensation filter. A motion compensation filter device (313) is provided with a motion compensation filter unit (30912) which switches filters to be caused to act on a full-sample image on a certain unit basis, and an MC filter parameter deriving unit (3039) which selects the unit of switching of the filters by the motion compensation filter unit.
(FR) L'objet de la présente invention est de limiter le surdébit d'un drapeau indiquant un filtre de compensation de mouvement. Un dispositif de filtre de compensation de mouvement (313) est pourvu d'une unité filtre de compensation de mouvement (30912) qui commute des filtres devant être amenés à agir sur une image d'échantillon complet sur une certaine base unitaire, et une unité de déduction de paramètre de filtre MC (3039) qui sélectionne l'unité de commutation des filtres par l'unité de filtre de compensation de mouvement.
(JA) 動き補償フィルタを示すフラグのオーバーヘッドを抑制する。動き補償フィルタ装置(313)は、ある単位毎にフルサンプル画像に作用させるフィルタを切り替える動き補償フィルタ部(30912)と動き補償フィルタ部によるフィルタの切替単位を選択するMCフィルタパラメータ導出部(3039)とを備えている。
