Abstract

La présente invention concerne un procédé de détermination d'image de référence de capteur d'images comprenant une matrice de pixels détecteurs. Le procédé comprend l'acquisition d'une image de noir IN et de deux images I1 et I2 acquises dans des zones linéaires de détection du capteur. L'image de référence s'écrit :IR1=(Rm x I1-I2)/(Rm-1), ou Rm , ou Fomule (I) représentant la valeur du pixel de l'image Ik détecté par le pixel détecteur situé à l'intersection de la ligne de rang i et de la colonne de rang j de la matrice de pixels détecteurs, et N représentant le nombre total de pixels de la matrice.
