Patent

CA 2206887

An article such as for example a motor vehicle at a publicity function is to be represented in front of different viewers (38) in the background of a stage (28) in the form of a virtual image (26). A presenter (40) is to stand in the image and give explanations. Disposed above the stage (28) is an image source (12, 14). It projects an image, a film, on to a reflecting surface (18) on the floor (30) of the stage (28). Behind that reflecting surface (18) a transparent smooth foil (20) extends at 45° from the ceiling (32) to the floor (30). The image produced by the image source (12, 14) appears to the viewers (38) as a virtual image (26) behind the foil (20). The presenter (40) stands behind the foil (20) and in the middle of the image.

Un objet comme, par exemple, un véhicule automobile dans une manifestation publicitaire doit être projeté sous forme d'image virtuelle (26) à l'arrière-plan d'une scène (28) devant plusieurs spectateurs. Un présentateur (40) doit se tenir devant l'image pour donner des explications. Sur la scène (28), un projecteur (12,14) projette une image, un film, sur la surface réfléchissante (18) placée sur le sol (30) de la scène (28). A l'arrière de cette surface réfléchissante (18) défile un film transparent lisse (20) à 45 DEG entre le plafond (32) et le sol (30). Pour le spectateur (38), l'image projetée par le projecteur (12,14) apparaît sous forme d'image virtuelle (26) derrière le film (20). Le présentateur (40) se tient derrière le film (20) et au centre de l'image.
