Abstract

A 3-D film system, compatible with both current and future standards in high definition 3-D television, which is also suited to traditional two-dimensional projection. The system, which covers shooting and projection, makes use of the blocking phase of a first film to expose or project a second, parallel, film, which corresponds to the view of the second eye. The spectators use special glasses (7) which are synchronised with the alternative projection of the film, left and right, allowing them to watch the projection of the image on the left with the left eye only, and the projection of the image on the right with the right eye only, and to thereby recreate a single 3-D image.

Description

Depuis l'invention du cinématographe et de la photographie , les chercheurs ont conçu des systèmes de prise de vue et restitution d'images en relief
Par rapport à tous les systèmes de cinéma en relief existants , le système selon l'invention est compatible avec les futures normes de Télévision Haute
Définition et Relief et en même temps le film réalisé en relief peut être utilisé sur des appareils de projection classiques , obtenant ainsi une projection en deux dimensions , compatible avec les actuelles normes de télévision
La raison pour laquelle ce système a été conçu compatible à la fois avec les actuelles et les futures normes de télévision , est qu'il ne peut pas exister le cinéma sans la télévision , ni la télévision sans le cinéma
Pour mieux comprendre le contenu de l'invention il faut rappeller que dans le cinéma classique , prise de vue et projection , la pellicule est entraînée par un système à mouvement intermitent , composé de deux phases alternatives
PHASE D'EXPOSITION à la lumière , la pellicule reste immobile devant une fenêtre ; dans le cas de prise de vue , la lumière impressionne la pellicule; dans le cas de la projection , la lumière projette l'image contenue par la pellicule , sur un écran .Since the invention of cinematography and photography, researchers have designed systems for taking pictures and restoring images in relief
Compared to all existing relief cinema systems, the system according to the invention is compatible with future High Television standards
Definition and Relief and at the same time the film made in relief can be used on conventional projection devices, thus obtaining a two-dimensional projection, compatible with current television standards
The reason why this system was designed compatible with both current and future television standards, is that it cannot exist cinema without television, nor television without cinema
To better understand the content of the invention it should be remembered that in classic cinema, shooting and projection, the film is driven by an intermittent motion system, composed of two alternative phases
EXPOSURE PHASE to light, the film remains motionless in front of a window; in the case of shooting, the light impresses the film; in the case of projection, the light projects the image contained by the film, on a screen.

PHASE D'OBTURATION , la pellicule est déplacée pour passer à l'image suivante ; dans ce cas la fenêtre est obturée pour que la pellicule ne soit pas impressionnée pendant son mouvement dans le cas de prise de vue et pour que le mouvement de la pellicule ne soit pas perçu sur l'écran dans le cas de projection
Le système selon l'invention utilise la phase d' obturation d' une première pellicule pour 1' exposition d' une deuxième pellicule parallèle correspondant au point de vue du deuxième oeil
Donc , le système , prise de vue et projection selon l'invention utilise deux pelliculès parallèles dont le mouvement est en contretemps .SHUTTER PHASE, the film is moved to the next image; in this case the window is closed so that the film is not impressed during its movement in the case of shooting and so that the movement of the film is not perceived on the screen in the case of projection
The system according to the invention uses the phase of obturation of a first film for the exposure of a second parallel film corresponding to the point of view of the second eye.
Therefore, the system, shooting and projection according to the invention uses two parallel films whose movement is out of time.

Bien entendu , dans ce système le temps d'obturation doit être légèrement supérieur au temps de l'exposition
En conclusion , les images correspondant à l'oeil droit et l'oeil gauche sont filmées ou projetées alternativement à la fréquence de 24 images/seconde chacune
En projection , selon l'invention , les images gauche et droite sont projetées alternativement sur le même écran
Les images ainsi projetées sont perçues par le spectateur par l'intermédiaire d'une paire de lunettes spéciale dont les verres deviennent alternativement et en contretemps transparents et opaque s à la commande du système de synchronisation de la projection alternative gauche et droite .Of course, in this system the shutter time must be slightly higher than the exposure time
In conclusion, the images corresponding to the right eye and the left eye are filmed or projected alternately at the frequency of 24 images / second each
In projection, according to the invention, the left and right images are projected alternately on the same screen
The images thus projected are perceived by the viewer through a pair of special glasses, the lenses of which become alternately and at the same time transparent and opaque at the control of the synchronization system of the left and right alternative projection.

Le cerveau en combinant les deux images reçues reconstitue une seule image en trois dimensions
Une réalisation du système sera décrite en se référant aux figures, à titre d'exemple non limitatif
le système de prise de vue (Figure 1) comporte deux caméras classique (1) et (2) assemblées sur un support unique , en respectant les règles connues de la stéréoscopie ; un système de synchronisation (3) assure le fonctionnement en contretemps des obturateurs de ces deux caméras
La prise de vue , gauche et droite, est faite simultanément et en contretemps sur les deux pellicules contenues par les deux caméras
le système de projection (Figure 2) comporte deux projecteurs classiques (4) et (5) qui sont orientés pour projeter sur le meme écran les images gauche et droite contenues par les deux pellicules respectives . The brain by combining the two received images reconstructs a single three-dimensional image
An embodiment of the system will be described with reference to the figures, by way of nonlimiting example
the shooting system (Figure 1) comprises two conventional cameras (1) and (2) assembled on a single support, respecting the known rules of stereoscopy; a synchronization system (3) ensures the off-time operation of the shutters of these two cameras
The shooting, left and right, is done simultaneously and out of time on the two films contained by the two cameras
the projection system (Figure 2) comprises two conventional projectors (4) and (5) which are oriented to project on the same screen the left and right images contained by the two respective films.

Un système de synchronisation (6) assure le fonctionnement en contretemps des obturateurs de ces deux projecteurs et donc la projection alternative des images gauche et droite . A synchronization system (6) ensures the shutter operation of the shutters of these two projectors and therefore the alternative projection of the left and right images.

Le système de synchronisation (6) commande aussi le fonctionnement des lunettes spéciales (7) utilisées par les spectateurs et qui leur permettent de regarder la projection de l'image gauche uniquement avec l'oeil gauche et la projection de l'image droite uniquement avec l'oeil droit . Ainsi , le spectateur perçoit une image en trois dimensions, de n'importe quel position par rapport à l'écran e  The synchronization system (6) also controls the operation of the special glasses (7) used by the spectators and which allow them to watch the projection of the left image only with the left eye and the projection of the right image only with the right eye. Thus, the viewer perceives a three-dimensional image, from any position relative to the screen e
