CA 2174656

A 3D photographic printer and method of printing using a single large aperture projection lens (55, 56). The lens aperture is sufficient to cover all the projection angles necessary for filling the area under each lenticule with compressed images during printing. The printer uses an aperture plate (60) which is designed such that only one section of the aperture is opened at a time so that one of the 2D images (30) is exposed through the projection lens (55, 5?) at a proper projection angle onto the print material (80). With such an arrangement, the projection lens (55, 56) and the print material (80) are not required to move to different positions during printing.

L'invention concerne une imprimante pour produire des photographies 3D et un procédé d'impression utilisant une seule lentille de projection (55) avec une ouverture de grande taille. L'ouverture de la lentille est suffisamment importante pour couvrir tous les angles de projection nécessaires pour remplir la surface sous chaque lenticule avec des images comprimées durant l'impression. L'imprimante utilise une plaque (60) à ouverture qui est conçue pour qu'une partie seulement de l'ouverture soit ouverte à la fois, de sorte qu'une des images 2D (30) soit projetée par la lentille de projection (55) à un angle de projection approprié sur le support d'impression (90). Avec un tel agencement, la lentille de projection (55) et le support d'impression (90) n'ont plus besoin de se déplacer vers différentes positions durant l'impression.
