Abstract:
(EN)
A display device (100), comprising a light source apparatus (110), an image data processing module (120), an optical modulation apparatus (130), and an image synthesizing apparatus (140). The light source apparatus (110) emits a first light and a second light, and the image data processing module (120) determines, according to original image data, a color domain range of an image to be displayed, the original image data being based on a second color domain range (F2); if the color coordinates of at least part of the pixels of the image to be displayed are located within a predetermined region (P1), the second color domain range (F2) covers a first color domain range (F1) and is provided with a portion that exceeds the first color domain range (F1); the predetermined region (P1) is a region beyond the first color domain range (F1) and is a region in which an inner side of a border line of the second color domain range (F2) does not comprise a border line; the image data processing module (120) converts original image data of the at least part of the pixels for which the color coordinates are located within the predetermined region (P1) to first sub-data based on the first color domain range (F1) and second sub-data based on the second color domain range (F2); the optical modulation apparatus (130) modulates the first light and the second light respectively according to the first sub-data and the second sub-data so as to obtain an image light, and the image synthesizing apparatus (140) synthesizes the image light to display an image.
(FR)
L'invention concerne un dispositif d'affichage (100), comprenant un appareil de source de lumière (110), un module de traitement de données d'image (120), un appareil de modulation optique (130), et un appareil de synthèse d'image (140). L'appareil de source de lumière (110) émet une première lumière et une seconde lumière, et le module de traitement de données d'image (120) détermine, selon des données d'image d'origine, une plage de domaine de couleur d'une image à afficher, les données d'image d'origine étant basées sur une seconde plage de domaine de couleur (F2); si les coordonnées de couleur d'au moins une partie des pixels de l'image à afficher s'inscrivent dans une région prédéterminée (P1), la seconde plage de domaine de couleur (F2) recouvre une première plage de domaine de couleur (F1) et est pourvue d'une partie qui dépasse la première plage de domaine de couleur (F1); la région prédéterminée (P1) est une région au-delà de la première plage de domaine de couleur (F1) et est une région dans laquelle un côté interne d'une ligne de bordure de la seconde plage de domaine de couleur (F2) ne comprend pas de ligne de bordure; le module de traitement de données d'image (120) convertit des données d'image d'origine de ladite partie des pixels pour laquelle les coordonnées de couleur s'inscrivent dans la région prédéterminée (P1) en premières sous-données sur la base de la première plage de domaine de couleur (F1) et en secondes sous-données sur la base de la seconde plage de domaine de couleur (F2); l'appareil de modulation optique (130) module respectivement la première lumière et la seconde lumière selon les premières sous-données et les secondes sous-données de façon à obtenir une lumière d'image, et l'appareil de synthèse d'image (140) synthétise la lumière d'image pour afficher une image.
(ZH)
一种显示设备(100),包括光源装置(110)、图像数据处理模块(120)、光调制装置(130)及图像合成装置(140)。光源装置(110)发出第一光与第二光,图像数据处理模块(120)依据原始图像数据判断一幅待显示图像的色域范围,原始图像数据基于第二色域范围(F2),若该幅待显示图像的至少部分像素的色坐标位于预定区域(P1)内,第二色域范围(F2)覆盖第一色域范围(F1)且具有超出的部分,预定区域(P1)为第一色域范围(F1)之外且第二色域范围(F2)的边界线内侧不包括边界线的区域,图像数据处理模块(120)将色坐标位于该预定区域(P1)的至少部分像素的原始图像数据转换为基于第一色域范围(F1)的第一子数据与基于第二色域范围(F2)的第二子数据。光调制装置(130)依据第一子数据、第二子数据分别调制第一光、第二光获得图像光,图像合成装置(140)将图像光合成显示图像。
