Title
(EN) DISPLAY DEVICE AND IMAGE CROPPING METHOD
(FR) DISPOSITIF D'AFFICHAGE ET PROCÉDÉ DE RECADRAGE D'IMAGES
(ZH) 显示设备及图像裁剪方法
Abstract
(EN) Disclosed are a display device and an image cropping method. The display device comprises: a projection assembly; a screen, which is configured to be capable of curling up and down; a driving assembly, which is used for driving the screen so that same is unfolded or curled; a monitoring assembly, which is used for monitoring state information of the screen during the unfolding or curling process, and feeding back the state information of the screen to a controller; and the controller, which is used for executing: during the process of the screen being unfolded or curled according to a preset speed curve, and the projection assembly projecting a preset image according to a preset height curve, determining the current height of the screen according to the state information of the screen; if the current height of the screen is lower than the display height of the preset image, dividing the preset image into a first image and a second image according to the current height of the screen, wherein the height of the second image is not greater than the current height of the screen; and controlling the projection assembly to project the preset image, such that the screen only displays the second image.
(FR) L’invention concerne un dispositif d’affichage et un procédé de recadrage d'images. Le dispositif d'affichage comprend : un ensemble de projection ; un écran, qui est configuré pour être capable de s'enrouler vers le haut et vers le bas ; un ensemble d'entraînement, qui est utilisé pour entraîner l'écran de sorte que celui-ci soit déplié ou enroulé ; un ensemble de surveillance, qui est utilisé pour surveiller les informations d'état de l'écran pendant le processus de dépliage ou d'enroulement, et renvoyer les informations d'état de l'écran à une commande ; et la commande, qui est utilisée pour exécuter : pendant le processus de dépliage ou d'enroulement de l'écran selon une courbe de vitesse prédéfinie, et la projection par l'ensemble de projection d'une image prédéfinie selon une courbe de hauteur prédéfinie, déterminer la hauteur actuelle de l'écran selon les informations d'état de l'écran ; si la hauteur actuelle de l'écran est inférieure à la hauteur d'affichage de l'image prédéfinie, diviser l'image prédéfinie en une première image et une seconde image selon la hauteur actuelle de l'écran, dans lequel la hauteur de la seconde image n'est pas supérieure à la hauteur actuelle de l'écran ; et commander l'ensemble de projection pour projeter l'image prédéfinie, de sorte que l'écran affiche uniquement la seconde image.
(ZH) 本申请一些实施方式公开一种显示设备及图像裁剪方法,显示设备包括:投影组件;屏幕,被配置为可卷曲升降;驱动组件,用于驱动所述屏幕展开或卷曲;监测组件,用于监测所述屏幕展开或卷曲过程中的状态信息,并向控制器反馈所述屏幕的状态信息;控制器,用于执行:在所述屏幕按照预设速度曲线展开或卷曲且所述投影组件按照预设高度曲线投射预设图像的过程中,根据屏幕的状态信息确定当前屏幕的高度;如果当前屏幕的高度低于预设图像的显示高度,根据当前屏幕的高度将预设图像划分为第一图像和第二图像,所述第二图像的高度不大于所述当前屏幕的高度;控制所述投影组件投射预设图像,以使所述屏幕仅显示所述第二图像。
