Abstract

L'invention concerne un système d'affichage d'image capable d'afficher clairement, avec facilité, des sections dignes d'intérêt d'un écran d'affichage dans un dispositif d'affichage d'image pour afficher des images de sortie d'un terminal d'information ; un terminal d'information ; ainsi qu'un procédé et un programme de commande de terminal d'information. Ce système d'affichage d'image est configuré à partir : d'un terminal d'information qui affiche une pluralité de fenêtres d'application ; et d'au moins un dispositif d'affichage d'image qui est connecté au terminal d'information, et qui affiche le contenu d'une fenêtre d'application à partir des fenêtres d'application. Le terminal d'information est pourvu d'un moyen de désignation pour désigner l'état d'affichage et la destination d'affichage du contenu de la fenêtre d'application. Le dispositif d'affichage d'image désigné par le moyen de désignation est configuré pour afficher dans un état semblable ou différent du contenu d'affichage de la fenêtre d'application du terminal d'information, conformément à l'état d'affichage désigné par le moyen de désignation.
