Title (EN) MEASUREMENT METHOD AND MEASUREMENT SYSTEM THEREOF
(FR) PROCÉDÉ DE MESURE ET SYSTÈME DE MESURE ASSOCIÉ
(ZH) 测量方法及其测量系统
Abstract:
(EN) Disclosed are a measurement method and a measurement system thereof, used to measure the contrast of a display device (01). The measurement method comprises: controlling the display device (01) to display a first image, and testing the brightness at a central area of the first image; controlling the display device (01) to display a second image, and testing the brightness at a central area of the second image; and determining the contrast. The first image and the second image both have multiple areas having different grayscale levels. The central area of the first image is an area having a maximum grayscale level in the first image, and the central area of the second image is an area having a minimum grayscale level in the second image. The measurement method and measurement system can use the same baseline to measure the performance of products, thereby eliminating the influence of an algorithm.
(FR) La présente invention concerne un procédé de mesure et un système de mesure utilisés pour mesurer le contraste d'un dispositif d'affichage (01). Le procédé de mesure comprend les étapes consistant à : commander le dispositif d'affichage (01) pour afficher une première image, et tester la luminosité au niveau d'une zone centrale de la première image; commander le dispositif d'affichage (01) pour afficher une seconde image, et tester la luminosité au niveau d'une zone centrale de la seconde image; et déterminer le contraste. La première image et la seconde image ont toutes deux de multiples zones ayant différents niveaux de gris. La zone centrale de la première image est une zone ayant un niveau de gris maximal dans la première image, et la zone centrale de la seconde image est une zone ayant un niveau de gris minimal dans la seconde image. Le procédé de mesure et le système de mesure peuvent utiliser la même ligne de base pour mesurer la performance des produits, éliminant ainsi l'influence d'un algorithme.
(ZH) 一种测量方法及其测量系统,用于测量显示装置(01)的对比度,包括:控制显示装置(01)显示第一画面,对第一画面的中心区域的亮度进行测试;控制显示装置(01)显示第二画面,对第二画面的中心区域的亮度进行测试;确定对比度。第一画面和第二画面均具有多个不同灰阶等级的区域;第一画面的中心区域为第一画面中的最大灰阶等级区域,第二画面的中心区域为第二画面中的最小灰阶等级区域。该测量方法和测量系统可以使用同一基准衡量各产品性能,排除了算法影响。
