Abstract

Le procédé selon l'invention consiste à faire défiler le film (1) dans un montage optique comprenant, d'un côté du film, au moins deux sources de lumière (3a, 3b), de longueurs d'onde différentes qui éclairent le film dans une zone de faible largeur, et, de l'autre côté du film, un objectif (7) qui projette les deux images de la zone éclairée par les faisceaux (4a, 4b) émanant des deux sources, sur deux éléments linéaires photosensibles (6, 7-9) respectivement adaptés aux longueurs d'onde des deux sources, et à comparer les données numériques délivrées par les deux éléments de détection, le résultat de cette comparaison servant à effectuer la susdite détection et la susdite correction. Elle s'applique à la détection de défauts tels que souillures, rayures, poussières sur un film.
