Le procédé de traitement d'image selon les modes de réalisation de la présente invention peut non seulement prendre en charge de multiples caméras fonctionnant en même temps au moyen de la puce de prétraitement (101), mais peut également utiliser pleinement la capacité de traitement informatique du processeur (10) pour traiter la première image et les secondes images, ce qui permet d'économiser des coûts.
