Patent

CA 2330292

An "immersive experience" motion picture theatre is provided either as a purpose-built structure or as a "retro-fit" of an existing domed theatre. The theatre of the invention has an audience seating deck (20) which slopes downwardly towards a screen (22) of part-cylindrical shape. The screen slopes upwardly and extends above the seating deck as well as wrapping around the sides of the seating deck. A projector (26) located within the seating deck (20) projects images onto the screen (22) about an upwardly oriented projection axis, through an orthographic fisheye lens which minimizes distortion of centre regions of the images. In this way, motion pictures that have been shot for showing on domed screens can be successfully projected onto the curved screen (22) of the invention.

L'invention concerne une salle de cinéma "d'immersion" à construire spécialement ou à adapter à une salle de cinéma à coupole préexistante. Ladite salle de cinéma de l'invention comporte un plancher à gradins (20) qui descend vers un écran (22) de forme partiellement cylindrique. L'écran est incliné vers le haut, s'étend au-dessus du plancher à gradins et enveloppe les côtés du plancher. Un projecteur (26) situé dans le plancher à gradins (20) projette des images sur l'écran (22), autour d'un axe de projection orienté vers le haut, à travers un oeil de poisson orthographique qui minimise la distorsion des régions centrales des images. Ainsi, les films qui ont été tournés pour être vus sur des écrans hémisphériques peuvent être projetés efficacement sur l'écran hémisphérique (22) de l'invention.
