Abstract

Procédé de simulation d'un rendu de support de prise de vue dit rendu cible, comprenant les étapes successives suivantes :a) la numérisation d'images (12) saisies sur un premier support numérique (10) et d'au moins un témoin de sensitométrie (14) enregistré sur le même support, de façon à obtenir des codes numériques initiaux pour un ensemble de pixels pris dans les images et le témoin de sensitométrie,b) l'établissement, à partir des codes numériques du témoin de sensitométrie (26), d'une relation de sensitométrie initiale (26) pour le premier support numérique, la relation de sensitométrie initiale (26) reliant des codes numériques à des valeurs d'exposition lumineuse du support,c) l'établissement, à partir d'une relation de sensitométrie cible (28), correspondant au rendu cible, de nouveaux codes numériques pour une pluralité de pixels d'image, les nouveaux codes numériques étant établis de telle sorte que le nouveau code numérique et le code numérique initial de chaque pixel sont associées à une même valeur d'exposition, respectivement par la relation de sensitométrie cible (28) et la relation de sensitométrie initiale (26).
