Abstract

L'invention concerne un procédé et un appareil de commande de fréquence d'image d'un dispositif électronique, un support d'informations et un dispositif électronique. Le procédé consiste : à déterminer que la fréquence de rafraîchissement d'un écran d'affichage d'un dispositif électronique est supérieure à une première valeur définie (101) ; à déterminer, parmi les applications en cours d'exécution, une application cible satisfaisant une condition de réduction de fréquence d'image définie (102) ; et à réduire un taux de fréquence d'image de création de l'application cible en fonction de l'état de réduction de fréquence d'image défini (103). En réduisant le taux de fréquence d'image de création d'une application cible, la consommation d'énergie d'un dispositif électronique peut être réduite.
