Abstract

L'invention concerne un procédé et un dispositif d'acquisition d'image. Le procédé consiste à : avant de prévisualiser, en plein écran, une image acquise par un appareil photo d'un terminal, acquérir un premier taux de résolution d'un écran d'affichage du terminal et un second taux de résolution de l'appareil photo du terminal; comparer le premier taux de résolution au second taux de résolution; et, si le premier taux de résolution n'est pas cohérent avec le second taux de résolution, acquérir une image ayant un taux de résolution cohérent avec le second taux de résolution. La présente invention résout le problème lié, dans l'état de la technique, au fait qu'une image ne peut pas être affichée à un bord supérieur et un bord inférieur d'une interface de prévisualisation d'un téléphone mobile lorsqu'une proportion dimensionnelle d'un écran de téléphone mobile n'est pas cohérente avec le taux de résolution d'un appareil photo de téléphone mobile. L'invention améliore ainsi l'expérience de l'utilisateur.
