Title (EN) IMPROVING APPEARANCE OF A LIGHT-DIFFUSING SCREEN
(FR) AMELIORATION DE L'ASPECT D'UN ECRAN DE DIFFUSION DE LUMIERE
Abstract:
(EN) The system according to the present invention includes a light-diffusing screen having a projected image that includes the intrinsic random optical patterns superimposed on a scene image. An electronic photosensor is used to capturing the scene image and an image processor employs algorithms that reduce the random optical patterns that are inherent to the light-diffusing screen.
(FR) La présente invention concerne un système comportant un écran de diffusion de lumière présentant une image projetée comprenant les motifs optiques aléatoires intrinsèques superposés sur une image de scène. Un capteur optique électronique est utilisé pour capter l'image de scène et un processeur d'images utilise des algorithmes qui réduisent les motifs optiques aléatoires qui sont inhérents à l'écran de diffusion de lumière.
