Abstract

Un procédé comprend la réception de trames vidéo d'une vidéoconférence entre un premier utilisateur et un second utilisateur, les trames vidéo comprenant une image du premier utilisateur générée par une caméra ayant une seule lentille, la détermination d'un premier ensemble de paramètres pour ajuster un point de vue de l'image sur la base d'une ligne de visée de la caméra et d'une position sur un écran d'affichage du premier utilisateur, la détermination d'un second ensemble de paramètres pour ajuster le point de vue de l'image sur la base d'une ligne de visée du second utilisateur, et l'ajustement du point de vue de l'image du premier utilisateur sur la base d'une combinaison du premier ensemble de paramètres et du second ensemble de paramètres pour générer une image à point de vue ajusté du premier utilisateur à des fins d'affichage sur un écran d'affichage du second utilisateur.
