Abstract: front page image
(EN)Rear projection system comprising a rear projection cabinet with a rectangular opening, a projection screen covering said opening and a projector located at least partly in said cabinet, wherein the sides of the rectangular opening are curved. The sides of the opening are curved at least as much as curvatures of sides of an image to be projected by the projector, which curvatures are due to distortion caused by the projector.
(FR)L'invention concerne un système de projection arrière comprenant une chambre de projection arrière dotée d'une ouverture rectangulaire, un écran de projection recouvrant ladite ouverture et un projecteur situé au moins en partie dans ladite chambre, les côtés de l'ouverture rectangulaire étant courbés. Les côtés de l'ouverture sont courbés au moins autant que les inclinaisons des côtés d'une image à projeter par le projecteur, ces inclinaisons étant dues aux distorsions entraînées par le projecteur.
