Le procédé consiste ensuite à calculer un paramètre de mise en proportions de l'image source et de la position correspondante de l'image source dans l'arrière-plan cible en fonction des paramètres de l'image source et des paramètres de l'arrière-plan. Le procédé consiste aussi à zoomer l'image source en fonction du paramètre de mise en proportion. Le procédé consiste enfin à produire en sortie une image en combinant, dans l'arrière-plan cible, l'image source qui a été zoomée en fonction de la position correspondante de l'image source.
