Le procédé consiste à : recevoir une instruction de photographie et acquérir une première trame d'image et une seconde trame d'image à l'aide d'un appareil de prise de vues avant et d'un appareil de prise en vues arrière ; obtenir des zones d'image de personne dans la première trame d'image et la seconde trame d'image, puis utiliser les zones d'image de personne comme une première zone d'image de personne et une seconde zone d'image de personne, respectivement ; ajuster la première zone d'image de personne en fonction d'un paramètre de longueur et d'un paramètre de largeur de la seconde zone d'image de personne, de sorte que la première zone d'image de personne corresponde à la seconde zone d'image de personne ; et synthétiser la première zone d'image de personne ajustée dans la seconde trame d'image pour produire une photographie de groupe. Au moyen des modes de réalisation de la présente invention, une photographie de groupe comprenant un photographe peut être rapidement obtenue à l'aide d'une technologie de synthèse d'image lorsqu'une photographie est prise, de manière à faire gagner du temps à un utilisateur. De plus, un rapport d'images de personne dans la photographie peut en outre être ajusté, de sorte que les images de personne dans la photographie de groupe soient plus harmonieuses et plus jolies sur le plan artistique.
