Abstract:
(EN) Provided is a technique that is capable of improving image quality by utilizing the dynamic range of a panel when images are displayed that are indicated by signals of a maximum luminance that is lower than the panel peak luminance. A image processing device (2, 11) is provided with: a conversion unit (6) that converts values, among gradation values taken by respective pixels in image signals, which are equal to or lesser than a gradation value corresponding to the maximum luminance level, into luminance values; and an adjustment unit (7) that carries out adjustment so as to raise a luminance value, among the luminance values, that is equal to or greater than a prescribed value.
(FR) L'invention concerne une technique qui permet d'améliorer la qualité d'image en utilisant la plage dynamique d'un panneau lorsque des images affichées sont indiquées par des signaux d'une luminance maximale qui est inférieure à la luminance de crête du panneau. Un dispositif de traitement d'image (2, 11) comprend : une unité de conversion (6) qui convertit des valeurs, parmi des valeurs de gradation prises par des pixels respectifs dans des signaux d'image, qui sont égales ou inférieures à une valeur de gradation correspondant au niveau de luminance maximal, en valeurs de luminance ; et une unité de réglage (7) qui effectue un réglage de façon à élever une valeur de luminance, parmi les valeurs de luminance, qui est supérieure ou égale à une valeur prescrite.
(JA) パネルピーク輝度よりも低い最大輝度の信号が示す映像を表示する際に、パネルのダイナミックレンジを活かし、且つ映像品位を向上させることができる技術を提供する。映像処理装置(2、11)は、映像信号において各画素が取る階調値のうち、最大輝度レベルに対応する階調値以下の値を、輝度値に変換する変換部(6)と、上記輝度値のうち、所定の値以上の輝度値を持ち上げるように調整する調整部(7)と、を備えている。
