Abstract

L'invention concerne un procédé de photographie et un terminal mobile. Le procédé de photographie de la présente invention comprend les étapes suivantes : la détermination, lorsqu'il est détecté qu'une caméra de recherche de vue s'étend hors d'une coque à travers une ouverture, d'un objet photographié ; l'obtention d'un angle cible entre la position de l'objet photographié et une position prédéfinie d'un capteur d'image dans une période de temps prédéfinie avant un moment cible, le moment cible étant un moment où chaque trame d'image est générée selon l'objet photographié ; et lorsque l'angle cible est différent d'un angle prédéfini, l'ajustement de l'angle cible par rapport à l'angle prédéfini par commande de la caméra de recherche de vue pour la faire pivoter ; et la photographie de l'objet photographié pour générer la trame d'image.
