Abstract:
(EN) An image processing device according to the present invention is provided with: a base component extraction unit for extracting a base component from image components included in a video signal; a component adjustment unit for performing component adjustment for the base component in such a manner that a proportion of the base component to the image components becomes larger as the brightness of an image corresponding to the video signal increases; and a detail component extraction unit for extracting a detail component by using the image components and the base component which has been subjected to the component adjustment by the component adjustment unit.
(FR) La présente invention concerne un dispositif de traitement d'image qui comprend : une unité d'extraction de composant de base pour extraire un composant de base à partir de composants d'image inclus dans un signal vidéo ; une unité d'ajustement de composant pour effectuer un ajustement de composant pour le composant de base de telle sorte qu'une proportion du composant de base par rapport aux composants d'image devienne plus grande au fur et à mesure que la luminosité d'une image qui correspond au signal vidéo augmente ; et une unité d'extraction de composant de détail pour extraire un composant de détail en utilisant les composants d'image et le composant de base qui a été soumis à l'ajustement de composant par l'unité d'ajustement de composant.
(JA) 本発明にかかる画像処理装置は、映像信号に含まれる画像成分からベース成分を抽出するベース成分抽出部と、映像信号に対応する画像の明るさが大きくなるほど、画像成分に対してベース成分が占める割合が大きくなるようにベース成分の成分調整を行う成分調整部と、画像成分と、成分調整部による成分調整後のベース成分とを用いてディテール成分を抽出するディテール成分抽出部と、を備える。
