Abstract

L'invention porte sur une technique pour faire varier automatiquement la dimension d'une fenêtre d'affichage d'image mobile animée en fonction de la commutation de fenêtres actives pour soulager le problème de l'utilisateur lorsqu'il réalise d'autres opérations tout en affichant l'image animée. Un dispositif électronique dans lequel un système à multiples fenêtres fonctionne détecte la commutation des fenêtres actives et, si la commutation des fenêtres actives est la commutation de la fenêtre d'affichage d'image animée vers d'autres fenêtres, change la fenêtre d'affichage d'image animée de la dimension courante à une petite dimension.
