Patent

CA 2492687

The invention relates to an autostereoscopic projection system comprising at least one projector (4) and at least one filter array (F~1, F~2) which is provided with a plurality of filter elements that are disposed in columns and rows. Bits of information about views of a scene or an object are projected onto a projection screen (3) by means of said projector/s (4), where said bits of information are reproduced on image-reproducing elements and are made visible to at least one viewer (5) after penetrating one or several filter arrays (F~1, F~2). The image-reproducing elements correspond with associated filter elements regarding the direction of extension of the bits of information such that a viewer (S) sees mostly bits of information from a first selection of views with one eye while seeing mostly bits of information from a second selection of views with the other eye, whereby an impression of space is created for the viewer (5).

Syst­me de projection autost~r~oscopique, qui comporte au moins un projecteur (4) et au moins un groupe de filtres (F´1?, F´2?) constitu~ d'une pluralit~ d'~l~ments filtres plac~s en rang~es et en colonnes. Selon ledit syst­me, des informations partielles de vues d'une sc­ne ou d'un objet sont projet~es ~ l'aide du (des) projecteur(s) (4) sur un ~cran de projection (3), et ces informations partielles sont reproduites sur des ~l~ments de reproduction d'images et sont rendues visibles pour au moins un observateur (5), apr­s avoir travers~ un ou plusieurs des groupes de filtres (F´1?, F´2?). Les ~l~ments de reproduction d'images correspondent ~ des ~l~ments filtres associ~s, concernant le sens de propagation des informations partielles, de mani­re telle qu'un observateur (5) per×oit optiquement avec un oeil principalement des informations partielles appartenant ~ une premi­re s~lection et avec l'autre oeil principalement des informations partielles appartenant ~ une seconde s~lection tir~e des vues, ce qui produit pour l'observateur (5) une impression st~r~oscopique.
