Abstract

Il est divulgué un procédé et un dispositif de détection dynamique d'une trace de lumière parasite dans une image numérique acquise par un dispositif optique. Le procédé consiste à extraire et déterminer sans calculs complexes des valeurs issues de paramètres connus de l'image et à comparer en temps réel ces valeurs avec des seuils déterminés empiriquement pour confirmer ou infirmer la présence d'une trace de lumière parasite dans une ou plusieurs images.There is disclosed a method and a device for dynamically detecting a trace of stray light in a digital image acquired by an optical device. The method consists in extracting and determining without complex calculations values resulting from known parameters of the image and in comparing these values in real time with empirically determined thresholds to confirm or rule out the presence of a trace of stray light in one or more images.
