Abstract

L'invention concerne un procédé de transmission d'informations d'image. Le procédé comporte les étapes consistant à: ajuster un kit de développement logiciel correspondant dans une application de caméra, de telle façon qu'un espace de mémoire d'images de l'application de caméra servant à sauvegarder des images soit partagé avec une application tierce; acquérir l'espace de mémoire d'images pour déterminer des informations de descripteur correspondantes de l'espace de mémoire d'images; lorsqu'une instruction de transmission d'images est détectée, charger les informations de descripteur pour déterminer l'espace de mémoire d'images correspondant; et transmettre des informations d'images présentes dans l'espace de mémoire d'images à l'application tierce.
