Abstract

The invention relates to a method for stereoscopic vision aiming to achieve relief by the use of a pair of spectacles with conical conduits (1) in such a way that on the screen where the stereo images are placed side by side (I and II), the right eye seeing the left image and the left eye the right image; the sensation of relief is obvious and without apparent viewing fatigue. These pairs of spectacles can be equipped with an optical system with two lenses (5 and 3) allowing magnification of the image. In this example, the cubes I and II are seen as a single cube in relief with the lettering III.

Description

Ce procédé vise l'obtention d'une image en relief en regardant deux images jumelées, stéréo et placées cte à côte par le biais d'une paire de lunettes munies de deux conduits coniques (Beaucoup de procédés de télévision ou de cinéma en relief ont été testés et fonctionnent mais la qualité de l'image est insuffisante, à part le procédé holographique qui, lui, est bon, mais trop gourmand en bande passante pour la transmission hertzienne ; c'est le pourquoi de ma présente démarche)
La prise de vue est assurée par une double caméra stéréo
Pour la télévision, une synthèse du signal vidéo est faite en sorte que les premières moitiés de chaque ligne repre- sentent l'image de droite et les secondes, l'image de gauche . Ces deux vues étant séparées par une fine zone verticale sans signal .Ce vidéo signal stéréo est ainsi envoyé à l'émetteur . Le téléviseur reçoit donc sur son écran deux vues parallèles gauche et droite d'un format carré et les plus grandes possibles . Le reste de l'écran reste vierge ou réservé à d'autres informations .This process aims at obtaining an image in relief by looking at two paired images, stereo and placed side by side by means of a pair of glasses provided with two conical conduits (Many methods of television or cinema in relief have been tested and working but the image quality is insufficient, apart from the holographic process which is good, but too greedy in bandwidth for wireless transmission; this is the reason for my present approach)
The shooting is ensured by a double stereo camera
For television, a synthesis of the video signal is made so that the first halves of each line represent the image on the right and the seconds, the image on the left. These two views are separated by a thin vertical zone without signal. This stereo video signal is thus sent to the transmitter. The television therefore receives on its screen two parallel left and right views in a square format and the largest possible. The rest of the screen remains blank or reserved for other information.

Pour le cinéma, le film est impressionné par les deux vues jumelées côte à c8te . La vue de gauche représente l'image de la caméra de droite et la vue de droite celle de la caméra de gauche
La perception du relief s'obtient en visionnant l'écran par l'intermédiaire d'une paire de conduits coniques (1), fixés sur une monture comme une paire de lunettes . La petite extrémité ducône (3) se termine par un embout de section carrée (4) . Les cônes sont ajustés sur la monture de façon que si l'oeil droit vise l'image de gauche, l'oeil gauche captera automatiquement l'image de droite
Les cônes sont faits à la façon d'un soufflet d'appareil photographique, composés d'anneaux superposés et télescopiques de façon que la paire de lunettes se range facilement dans un étui peu encombrant (voir dessin)
L'intérieur des cônes sera de teinte mate, antireflet . La paire de lunettes est équipée d'un système optique permettant l'agrandissement de l'image . Une lentille est fixée sur la monture (5) et l'autre, entre l'extrémité du petit cône (3) et l'embout carré (4)
L'impression du relief est alors possible et sans fatigue apparente pour les organes de la vision, sauf lors d'une vision trop prolongée For cinema, the film is impressed by the two twin views side by side. The view on the left represents the image of the camera on the right and the view on the right that of the camera on the left
The perception of the relief is obtained by viewing the screen via a pair of conical conduits (1), fixed on a frame like a pair of glasses. The small end of the cone (3) ends with a square section end piece (4). The cones are adjusted on the frame so that if the right eye aims at the left image, the left eye will automatically capture the right image
The cones are made in the manner of a camera bellows, made up of superimposed and telescopic rings so that the pair of glasses can be easily stored in a space-saving case (see drawing)
The interior of the cones will be matte, anti-reflective. The pair of glasses is equipped with an optical system allowing the enlargement of the image. One lens is attached to the frame (5) and the other, between the end of the small cone (3) and the square tip (4)
The impression of the relief is then possible and without apparent fatigue for the organs of vision, except during too prolonged vision

Claims

flEvENDICAltIONS

1) Cinema and television method characterized by the fact that the image received on the screen is two stereo images placed side by side; the right view representing the image of the left camera and the left view that of the right camera. The appearance of the relief is obtained by viewing the screen through a pair of glasses with conical lines. The right eye looking at the left image and the left eye, the right image o

2) Method according to claim 1 characterized in that, for a television shooting in stereo, a synthesis of the video signal is made so that the left half-lines of the scan represent the right image and the half straight lines, the image on the left, each image in a square format

3) Method according to claim 1 characterized in that, for a cinematographic stereo shooting, the left half of the film is impressed by the view of the right camera and the other half of the film by the view of the left camera.

4) Method according to claim 1 characterized by viewing the screen via a pair of glasses with conical conduits (i) fixed on the frame (2). The small end of the cone (3) ending in square section (4). The cones are in superimposed, telescopic rings, like a camera bellows and they will be positioned vertically and laterally on the frame, so that the right eye sees entirely and only the left image and the left eye, the right image and this simultaneously

5) Method according to claim 1 characterized in that an optical system, composed of two lenses, one fixed on the frame (5), the other between the end of the small cone (3) and the square tip ( 4) allows the enlargement of the image
