Abstract

La présente invention concerne un terminal mobile comprenant : un module de surveillance conçu pour envoyer une première notification d'acquisition à un module d'acquisition lorsqu'il est détecté qu'un utilisateur trouve une vue et pour envoyer une notification de capture d'image à un module de capture d'image lorsqu'il est détecté que l'utilisateur confirme la capture d'image ; le module d'acquisition conçu pour recevoir la première notification d'acquisition et acquérir une image de prévisualisation de la vue trouvée par l'utilisateur ; un module d'analyse et de repérage conçu pour mener une analyse de cible d'arrière-plan effective sur l'image de prévisualisation obtenue et pour repérer une cible d'arrière-plan effective ; le module de capture d'image conçu pour recevoir la notification de capture d'image et générer une première image avec une première résolution correspondant à l'image de prévisualisation ainsi qu'une deuxième image avec une seconde résolution correspondant à la cible d'arrière plan effective repérée ; et un module de synthèse conçu pour synthétiser la première image et la deuxième image dans une troisième image, la seconde résolution étant égale à N fois la première résolution et N étant un nombre entier positif supérieur à 1. La solution technique évite de trop charger l'espace de stockage et améliore la qualité des images, améliorant ainsi l'expérience utilisateur.
