Abstract
Description
CINÉMA ET TÉLÉVISION HOLOGRAPHIQUE
La présente invention concerne un dispositif pour filmer, et projeter des films aux reliefs holographiques.CINEMA AND HOLOGRAPHIC TELEVISION
The present invention relates to a device for filming and projecting films with holographic reliefs.
Le cinéma en relief existant déjà est vu par des lunettes bi-polarisées à 45 et 1350 ceci créant des troubles d'ordre neurologiques.The already existing relief cinema is seen by bi-polarized glasses at 45 and 1350 this creating neurological disorders.
Le dispositif selon l'invention permet de remédier à cet inconvénient.The device according to the invention overcomes this drawback.
n comporte en effet selon une première caractéristique des lunettes polarisées à 900 (le champ de vision étant de 1800 divisé par le nombre d'yeux) pour le cinéma. 900 étant la polarité du tube cathodique pour la télévision.n indeed has, according to a first characteristic, glasses polarized at 900 (the field of vision being 1800 divided by the number of eyes) for the cinema. 900 being the polarity of the cathode ray tube for television.
n comporte comme seconde caractéristique: S caméras à lentilles polarisées à 900 depuis le centre de la lentille. n has as a second characteristic: S cameras with lenses polarized at 900 from the center of the lens.
n comporte comme troisième caractéristique 4 obturateurs d'objectifs de la moitié verticale (900) des lentilles de pnses de vue. n comprises as a third characteristic 4 lens shutters of the vertical half (900) of the viewing lenses.
n comporte comme quatrième caractéristique les angles de dispositions des caméras de prises de vues qui sont: 3 caméras centrales, dont deux avec obturateurs d'objectifs, ce qui crée une demi image gauche + une demi image droite + une image entière.n has as a fourth characteristic the angles of arrangement of the shooting cameras which are: 3 central cameras, two of which with lens shutters, which creates a half left image + a half right image + an entire image.
2 caméras aussi avec obturateur d'objectifs (même principe gauche droite ce qui crée une demi image gauche + une demi image droite située à 450 des caméras centrales et filmant avec des lentilles polarisées à 900. 2 cameras also with lens shutter (same principle left right which creates a half left image + a half right image located at 450 from the central cameras and filming with polarized lenses at 900.
ll comporte comme cinquième caractéristique, de régler la même profondeur de champ pour les 5 campas qui sont aussi synchronisées en temps et mouvements. As a fifth characteristic, it includes setting the same depth of field for the 5 campas which are also synchronized in time and movement.
n comporte comme sixième caractéristique lors de la projection d'inverser les angles de disposition des appareils de projection de la manière suivante:
La caméra sans obturateurs d'objectifs reste centrale.n includes the sixth characteristic during projection of reversing the angles of arrangement of projection devices in the following manner:
The camera without lens shutters remains central.
Les deux caméras centrales avec obturateurs d'objectifs se placent à 450 (angle de disposition) à gauche et à droite de la caméra centrale.The two central cameras with lens shutters are placed at 450 (layout angle) to the left and right of the central camera.
Les 2 caméras qui étaient à 450 (angle de disposition) des 3 caméras centrales s'inversent respectivement l'une à la place de l'autre et deviennent appareils de projection.The 2 cameras which were at 450 (angle of arrangement) of the 3 central cameras respectively reverse one in place of the other and become projection devices.
n comporte comme septième caractéristique d'adapter: pour le cinéma : un écran semi hémisphérique pour la télévision: c'est le tube cathodique qui doit être polarisé à 900. n has as its seventh characteristic to adapt: for the cinema: a semi-hemispherical screen for television: it is the cathode ray tube which must be polarized at 900.
