CA 2579205

An image projection apparatus (100) comprises a projector (106), a frame (108), and a partially transparent screen (110). The frame (108) retains the screen (110) under tension, such that the screen (110) is inclined at an angle with respect to a plane of emission of light from the projector (106). The screen (110) has a front surface arranged such that light emitted from the projector (106) is reflected therefrom. The projector (106) projects an image such that light forming the image impinges upon the screen (11) such that a virtual image is created from light reflected from the screen (110), the virtual image appearing to be located behind the screen (110).

L'invention concerne un appareil de projection d'image (100) comprenant un projecteur (106), un cadre (108) et un écran partiellement transparent (110). Le cadre (108) retient l'écran (110) sous tension, de sorte que l'écran (110) peut être incliné selon un angle par rapport au plan d'émission de lumière provenant du projecteur (106). L'écran (110) possède une surface avant disposée de manière que la lumière émise par le projecteur (106) soit réfléchie par celui-ci. Le projecteur (106) projette une image de sorte que la lumière formant l'image empiète sur l'écran (11) en vue de créer une image virtuelle à partir de la lumière réfléchie par l'écran (110), cette image virtuelle semblant être située à l'arrière de l'écran (110).
