Abstract

Un système d'affichage d'image (10) comprend : un dispositif de reproduction (1) destiné à reproduire un contenu d'image dynamique ; un dispositif de commande distant (2) comprenant un dispositif de détection de valeur d'actionnement agencé pour être coulissable de la droite vers la gauche afin d'actionner le dispositif de reproduction (1) à distance, et un dispositif d'affichage (3) destiné à afficher le contenu d'image dynamique reproduit par le dispositif de reproduction (2). Lorsqu'une avance rapide ou un retour rapide est donné comme instruction par actionnement du dispositif de détection de valeur d'actionnement à partir du dispositif de commande distant (2) lors de la reproduction d'un contenu d'image dynamique, on superpose des images en format timbre-poste d'une pluralité de scènes sélectionnées selon un intervalle de temps prédéterminé au voisinage de l'instant de reproduction pour un affichage sur l'image de reproduction du dispositif d'affichage (3) et on actualise les images en format timbre-poste pour un affichage selon un intervalle d'actualisation prédéterminé afin de réaliser un affichage d'avance rapide ou de retour rapide. La valeur d'actionnement du dispositif de détection de valeur d'actionnement décide de l'intervalle de temps prédéterminé et de l'intervalle d'actualisation.
