Abstract

L'invention concerne un procédé d'affichage d'image sur un terminal mobile et un terminal mobile correspondant. Le procédé comporte les étapes consistant à: détecter un mouvement d'un terminal mobile après que le terminal mobile a affiché le contenu d'une image sur un écran; déterminer, d'après un paramètre de mouvement détecté, un paramètre d'affichage de modification auto-adaptative de l'image; et actualiser, d'après le paramètre d'affichage, le contenu de l'image affiché sur l'écran. Dans la solution technique ci-dessus, en détectant un changement de position d'un terminal mobile, l'affichage d'une image est modifié avec celui-ci, c.à.d. est modifié de façon adaptative, et une seule main est ainsi nécessaire pour une utilisation rapide, sans influencer la qualité de l'image.
