Abstract

Procédé de traitement d'images, terminal, support de stockage informatique et programme informatique. Le procédé comporte les étapes suivantes: le terminal reçoit une première demande émanant d'un utilisateur pour lire une image GIF (S101); en réaction à la première demande, le terminal acquiert, à partir de sa mémoire, des données formatées en mode point BMP correspondant à l'image GIF, les données formatées en BMP étant des données obtenues en décodant l'image GIF (S102); le terminal lit les données formatées en BMP correspondant à l'image GIF (S103); et lorsque le terminal ne reçoit pas, dans la limite d'une durée préétablie, une seconde demande émanant de l'utilisateur pour lire l'image GIF, les données formatées en BMP correspondant à l'image GIF, stockées dans la mémoire du terminal, sont supprimées (S104). Selon le procédé, le temps de lecture d'images peut être raccourci, le rendement de lecture d'images peut être amélioré et agrément d'utilisation peut être accentué; et lorsqu'une condition de suppression est satisfaite, les données formatées en mode point correspondant à les images GIF, stockées dans la mémoire du terminal, peuvent être supprimées, évitant ainsi l'occupation de ressources excessives de mémoire.
