Title (EN) FLARE LIGHT COMPENSATION
(FR) COMPENSATION DE LUMIERE PARASITE
Abstract:
(EN) A system for compensating for flare light in an optical imaging system comprising a detector for detecting light from an image and producing a signal related to the amount of light detected, a flare light detector for viewing the flare light and producing a signal related to the amount of light viewed, and a compensator for reducing the signal from the image detector in response to the signal from the flare light detector.
(FR) Un système de compensation de lumière parasite dans un système d'imagerie optique comprend un détecteur destiné à détecter la lumière provenant d'une image, et à produire un signal relatif à la quantité de lumière détectée, un détecteur de lumière parasite destiné à visualiser la lumière parasite et à produire un signal relatif à la quantité de lumière visualisée, ainsi qu'un compensateur destiné à réduire le signal provenant du détecteur d'image, en réponse au signal provenant du détecteur de lumière parasite.
