Abstract

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.
