Description

DISPOSITIF VISUEL POUR METTRE EN RELIEF DES IMAGES PLANES VISUAL DEVICE FOR LINKING PLANAR IMAGES
La présente invention concerne un dispositif pour mettre en relief des images planes. Elle s'applique en particulier, mais non exclusivement, au visionnage d'images classiques en couleurs projetées dans des conditions normales de projection, soit par exemple avec des cadences de 24, 25 ou 29,97 images par seconde.The present invention relates to a device for highlighting flat images. It applies in particular, but not exclusively, to the viewing of conventional color images projected under normal projection conditions, that is to say for example with rates of 24, 25 or 29.97 images per second.
D'une manière générale, la perception du relief, ou stéréoscopie, fonctionne selon deux techniques différentes ; l'une consistant à obtenir deux points de vue, c'est-à-dire deux images, et l'autre consistant à travailler la présentation de l'image afin d'obtenir une image en relief avec le minimum de contraintes.Generally, the perception of the relief, or stereoscopy, works according to two different techniques; one consisting in obtaining two points of view, that is to say two images, and the other consisting in working on the presentation of the image in order to obtain an image in relief with the minimum of constraints.
Les techniques de prise de vue consistent par exemple à utiliser deux appareils synchronisés ou un appareil à deux objectifs. On peut également envisager plus simplement d'utiliser un seul appareil que l'on déplace pour prendre les deux photos .The techniques of shooting consist for example of using two synchronized cameras or a camera with two objectives. We can also consider more simply using a single camera that we move to take the two photos.
Les techniques de présentation de l'image consistent par exemple à utiliser la complémentarité des couleurs pour superposer les deux images sur le même tirage papier, ou le même support d'écran, et utiliser des lunettes à verres colorés pour que chaque œil ne voie que l'image qui lui est destinée ; cette technique portant le terme général d'anaglyphe.Image presentation techniques consist, for example, of using the complementarity of colors to superimpose the two images on the same paper print, or the same screen support, and use glasses with colored glasses so that each eye sees only the image intended for him; this technique bearing the general term anaglyph.
L'art antérieur connaît ainsi des lunettes, qui ont été très populaires, capables de voir en trois des dimensions. La technique anaglyphe présente les images, par exemple d'un film, de sorte qu'elles soient marquées d'un premier contour de couleur vert/bleu et d'un second contour de couleur rouge, et de la même manière, les lunettes de vision en trois dimensions comportent deux verres, habituellement en plastique, de couleur différentes, l'un vert/bleu et l'autre rouge.The prior art thus knows glasses, which have been very popular, capable of seeing in three dimensions. The anaglyph technique presents images, for example of a film, so that they are marked with a first outline in green / blue color and with a second outline red in color, and similarly, three-dimensional vision glasses have two lenses, usually plastic, of different colors, one green / blue and the other red.
Il a été également proposé d'utiliser un système optique qui projette une image sur la rétine de chaque œil. Néanmoins, cette technique nécessite de bloquer sa tête dans une certaine position déterminée par la direction du faisceau image projeté pour chaque œil.It has also been proposed to use an optical system which projects an image on the retina of each eye. However, this technique requires blocking his head in a certain position determined by the direction of the projected image beam for each eye.
On connaît d'autres techniques pour créer du relief, telles que notamment la lumière polarisée, les réseaux tramés, les images alternées ou l'hologramme, mais toutes ces techniques présentent un grand nombre d'inconvénients et sont difficilement applicables aux spectateurs de films, de vidéos, de jeux vidéos numériques.Other techniques are known for creating relief, such as in particular polarized light, halftone networks, alternating images or the hologram, but all these techniques have a large number of drawbacks and are difficult to apply to film viewers, videos, digital video games.
Les techniques proposées par l'art antérieur présentent un grand nombre d'inconvénient. Les systèmes de prise de vue nécessitent des installations complexes, et donc coûteuses, et limitent leurs applications, du fait du rendu des images, à destination de certaines professions, comme par exemple les instituts géographiques.The techniques proposed by the prior art have a large number of drawbacks. Shooting systems require complex, and therefore expensive, installations and limit their applications, due to the rendering of images, intended for certain professions, such as, for example, geographic institutes.
Par ailleurs, les techniques de présentation d'images, telles que les lunettes de vision en trois dimensions (technique anaglyphe) , nécessitent de modifier complètement les images ce qui entraîne des coûts additionnels de postproduction importants. La technique anaglyphe oblige également les spectateurs de ces images à porter les susdites lunettes ; les images ainsi modifiées étant inassimilable sans le port des lunettes de vision en relief . L'homme du métier connaît également le principe de l'effet Pulfrich qui se base sur deux éléments fondamentaux La persistance rétinienne qui permet la perception des images animées et la mise en décalage volontaire de la vision de chaque œil. Lors de la projection d'un film normal, les deux yeux perçoivent la même image au même moment . On a donc une image en deux dimensions. Mais si l'un des yeux perçoit l'image animée projetée quelques millisecondes plus tard que l'autre œil, un décalage de la vision se produit. Ce léger décalage permet au cerveau de recevoir suffisamment d'informations différentes pour recomposer une image en relief. Trois conditions sont indispensables pour une bonne perception de l'effet Pulfrich : • Le sujet doit être en mouvement de translation, de droite à gauche ou de gauche à droite.Furthermore, image presentation techniques, such as three-dimensional vision glasses (anaglyph technique), require completely modifying the images, which entails significant additional postproduction costs. The anaglyph technique also obliges the spectators of these images to wear the above glasses; the images thus modified cannot be assimilated without the wearing of raised vision glasses. Those skilled in the art also know the principle of the Pulfrich effect, which is based on two fundamental elements: Retinal persistence, which allows the perception of animated images and the voluntary shifting of the vision of each eye. When projecting a normal film, both eyes perceive the same image at the same time. So we have a two-dimensional image. But if one of the eyes perceives the moving image projected a few milliseconds later than the other eye, a shift in vision occurs. This slight offset allows the brain to receive enough different information to recompose an image in relief. Three conditions are essential for a good perception of the Pulfrich effect: • The subject must be in translational movement, from right to left or from left to right.
• Le spectateur doit utiliser des lunettes dont un verre est transparent et l'autre est un filtre gris, afin de créer le décalage. Le filtre gris doit être sur l'œil droit si le sujet se déplace vers la droite et inversement .• The spectator must use glasses of which one lens is transparent and the other is a gray filter, in order to create the offset. The gray filter should be on the right eye if the subject is moving to the right and vice versa.
• La vitesse du mouvement filmé doit être suffisamment rapide pour permettre aux deux yeux de recevoir deux images suffisamment décalées l'une de l'autre.• The speed of the filmed movement must be fast enough to allow the two eyes to receive two images that are sufficiently offset from each other.
La présente invention entend remédier aux inconvénients de l'art antérieur en offrant un dispositif apte à mettre en relief des images analogiques ou numériques sans prise de vue particulière ni préparation préalable des images. L'invention propose, à cet effet, un dispositif visuel pour mettre en relief des images planes comportant au moins deux verres, ou lentilles, teintés en surface ou dans la masse et présentant des couleurs différentes, caractérisé en ce que le premier verre comporte une couche de filtration apte à absorber, ou filtrer, plus de 84% de la lumière visible ; la couleur jaune étant quasi-totalement absorbée. Le second verre comporte une couche de filtration apte à absorber, ou filtrer, moins de 20% de la lumière visible ; la couleur jaune n'étant pas filtrée pas ledit verre.The present invention intends to remedy the drawbacks of the prior art by providing a device capable of highlighting analog or digital images without taking particular pictures or prior preparation of the images. The invention proposes, for this purpose, a visual device for highlighting flat images comprising at least two glasses, or lenses, tinted on the surface or in the mass and having different colors, characterized in that the first glass has a filtration layer capable of absorbing, or filtering, more than 84% of visible light; the yellow color being almost completely absorbed. The second glass has a filtration layer capable of absorbing, or filtering, less than 20% of visible light; the yellow color not being filtered by said glass.
Grâce à ces particularités, la présente invention permet non seulement de mettre en relief des images planes projetées sur un écran, ou analogue, mais également de mettre en sur-relief les images réelles et naturelles, par exemple utile dans le vol à vue pratiqué dans l'aviation civile.Thanks to these features, the present invention makes it possible not only to highlight plane images projected on a screen, or the like, but also to highlight real and natural images, for example useful in visual flight practiced in civil aviation.
Avantageusement, les deux susdits verres comprendront une couche de filtration complémentaire apte à filtrer totalement la couleur jaune sur le premier verre et à absorber la quasi-totalité de la couleur bleue sur l'autre verre. Dans ce cas, la couche de filtration complémentaire présentera une épaisseur d'environ 1,5 μm. Les qualités de filtration de cette couche de filtration complémentaire résident dans une filtration de la totalité des Ultra Violet B et de la quasi-totalité des Ultra Violet A.Advantageously, the two aforementioned glasses will include an additional filtration layer capable of completely filtering the yellow color on the first glass and of absorbing almost all of the blue color on the other glass. In this case, the additional filtration layer will have a thickness of approximately 1.5 μm. The filtration qualities of this additional filtration layer reside in filtration of all Ultra Violet B and almost all Ultra Violet A.
Selon un mode d'exécution de l'invention, le premier verre présentera une couleur sensiblement violette, composée avec des couleurs rouges (80 %) et bleues (75 %) , jaune (16 %) et gris métallisé miroir (épaisseur 1,5 micron) sur sa face extérieure. De la même manière, le second verre présentera une couleur sensiblement jaune orangé, composé avec des couleurs jaunes (90 %) et rougesAccording to an embodiment of the invention, the first glass will have a substantially purple color, composed with colors red (80%) and blue (75%), yellow (16%) and gray metallic mirror (thickness 1.5 micron) on its outer face. In the same way, the second glass will present a substantially orange-yellow color, composed with yellow (90%) and red colors
(80 %) , bleu (2 %) et gris métallisé miroir (1,5 microns) sur sa face extérieure. Selon un autre mode d'exécution de l'invention, la couche du premier verre filtrera 96 % de la lumière visible et la couche de filtration du second verre filtre 75 % de la lumière visible. De la sorte, l'ensemble des couleurs utilisées se trouve partiellement neutralisées en laissant ressortir une grosse partie des blancs, ce qui provoque une exagération des contrastes sur différents plans suivant leurs éloignements du sujet. Cette exagération des contrastes va donner au cerveau des informations visuelles que celui-ci va interpréter comme des couches successives de plan par rapport à son horizon. Il reconstituera par rapport à ses bases mémorielles un univers qui pourra ressembler à du 3D ou tout du moins que le sujet interprétera comme du 3D.(80%), blue (2%) and metallic gray mirror (1.5 microns) on its outer face. According to another embodiment of the invention, the layer of the first glass will filter 96% of the visible light and the filtration layer of the second glass filters 75% of the visible light. In this way, all of the colors used are partially neutralized, revealing a large part of the whites, which causes an exaggeration of the contrasts on different planes according to their distance from the subject. This exaggeration of contrasts will give the brain visual information that it will interpret as successive layers of plan with respect to its horizon. It will reconstitute in relation to its memory bases a universe which may resemble 3D or at least that the subject will interpret as 3D.
De préférence, le premier verre présente une couleur sensiblement violette, composé avec des couleurs rouges et bleues. De la même manière, le second verre présente idéalement une couleur sensiblement jaune.Preferably, the first glass has a substantially purple color, composed with red and blue colors. Likewise, the second glass ideally has a substantially yellow color.
Selon un mode d'exécution préféré de l'invention, la couche de filtration du premier verre filtre 91% de la lumière visible et la couche de filtration du second verre filtre 10% de la lumière visible. De la sorte, le premier verre, laissant passer 9% de la lumière visible, a pour conséquence l'ouverture de la pupille du spectateur (phénomène de mydriase) ; ceci provoquant un décalage de la perception de l'image en particulier par rapport à la perception de l'image issue du second verre. En effet, la pupille de l'autre œil, percevant 90% de la lumière visible, se ferme (phénomène de miosis) par rapport à l'autre œil et réceptionne une image principalement jaune ; les perceptions différentes des images issues des deux yeux ayant pour conséquence de « tromper » le cerveau et de mettre ainsi en relief des images classiques. Avantageusement, les deux verres, ou lentilles, sont des verres optiques organiques, par exemple de type CR 39, ou en plastique, par exemple en polycarbonate ou en acrylique. Par ailleurs, les verres, ou lentilles, pourront être classiquement des verres optiques de fusion ou des gelâtes optiques.According to a preferred embodiment of the invention, the filtration layer of the first glass filters 91% of the visible light and the filtration layer of the second glass filters 10% of the visible light. In this way, the first glass, allowing 9% of visible light to pass through, results in the opening of the spectator's pupil (mydriasis phenomenon); this causing a shift in the perception of the image in particular compared to the perception of the image from the second glass. Indeed, the pupil of the other eye, perceiving 90% of visible light, closes (miosis phenomenon) compared to the other eye and receives a mainly yellow image; the different perceptions of the images from the two eyes having the effect of "deceiving" the brain and thus highlighting classical images. Advantageously, the two glasses, or lenses, are organic optical glasses, for example of the CR 39 type, or plastic, for example polycarbonate or acrylic. Furthermore, the glasses, or lenses, could conventionally be optical fusion glasses or optical gelates.
Un mode de réalisation du dispositif selon l'invention sera décrit ci-après, avec référence aux dessins annexés dans lesquels :An embodiment of the device according to the invention will be described below, with reference to the accompanying drawings in which:
La figure 1 est une vue en perspective d'une paire de lunettes selon l'invention,FIG. 1 is a perspective view of a pair of glasses according to the invention,

La figure 5 représente un exemple d'abaques correspondant aux revêtements se trouvant sur chacun des verres.FIG. 5 represents an example of abacuses corresponding to the coatings on each of the glasses.
Sur les figures 1 à 3, le dispositif visuel selon l'invention est intégré, ou monté, sur une paire de lunettes 1, par exemple des lunettes de vue pour hommes. De la même manière, ce dispositif visuel pourra être rapporté, et fixé par clipsage, sur une paire de lunettes possédant déjà deux verres correcteurs ordinaires, ou adapté sur, ou par-dessus, des lentilles de contact.In FIGS. 1 to 3, the visual device according to the invention is integrated, or mounted, on a pair of glasses 1, for example eyeglasses for men. In the same way, this visual device can be added, and fixed by clipping, on a pair of glasses already having two ordinary corrective lenses, or adapted on, or over, contact lenses.
La paire de lunettes 1 comprend une monture 2 pour verres comportant deux branches 3, 4, fixées, par des moyens mécaniques, à un cadre 5 ; ces deux branches 3, 4, étant classiquement aptes à être déplacées selon un axe sensiblement perpendiculaire au cadre 5. Le cadre 5 comprend deux ouvertures 6, 7, sensiblement ovales destinés à loger deux verres 8, 9.The pair of glasses 1 comprises a frame 2 for glasses comprising two branches 3, 4, fixed, by mechanical means, to a frame 5; these two branches 3, 4, being conventionally able to be displaced along an axis substantially perpendicular to the frame 5. The frame 5 comprises two openings 6, 7, substantially oval intended to accommodate two glasses 8, 9.
Les verres 8, 9, sont ici des verres organiques de type CR 39. Néanmoins, on pourra envisager que ces verres 8, 9 sont en plastique, par exemple en polycarbonate ou en acrylique, ou en gelâtes optiques.The glasses 8, 9 are here organic glasses of the CR 39 type. However, it may be envisaged that these glasses 8, 9 are made of plastic, for example polycarbonate or acrylic, or optical gelates.
Les verres 8, 9, sont teintés, en surface ou dans la masse, de couleurs différentes, le premier verre 8 présentant une couleur violette, composée avec les couleurs rouges et bleues, tandis le second verre 9 présentant une couleur jaune. Les verres 8, 9, s'adapteront indifféremment dans l'une ou l'autre des ouvertures 7 ou 8 de sorte que lesdits verres 8, 9, peuvent correspondre à l'un ou l'autre des yeux 10, 11, d'un spectateur, non représenté sur les figures .The glasses 8, 9 are tinted, on the surface or in the mass, of different colors, the first glass 8 having a purple color, composed with the colors red and blue, while the second glass 9 having a yellow color. The glasses 8, 9, will adapt indifferently in one or the other of the openings 7 or 8 so that said glasses 8, 9, can correspond to one or the other of the eyes 10, 11, of a spectator, not shown in the figures.
Selon la figure 2, le premier verre 8, de couleur violette, correspond à l'œil droit 10 d'un spectateur et le second verre 9, de couleur jaune, correspond à l'œil gauche 11 du spectateur, et vice-versa.According to FIG. 2, the first glass 8, of purple color, corresponds to the right eye 10 of a spectator and the second glass 9, of yellow color, corresponds to the left eye 11 of the spectator, and vice versa.
Par ailleurs, les deux verres 8, 9, comportent chacun une couche de filtration différente, non représentée sur les figures. Dans cet exemple, la couche de filtration est fixée sur la surface des verres 8 et 9 , mais on pourra envisager que ladite couche est insérée dans les verres 8, 9. Le premier verre 8 comporte une couche de filtration apte à absorber, ou filtrer, plus de 80% de la lumière j visible ; la couleur jaune étant quasi-totalement absorbée. Le second verre 9 comporte une couche de filtration apte à absorber, ou filtrer, moins de 20% de la lumière visible ; la couleur jaune n'étant pas, ou quasiment pas, filtrée pas ledit verre.Furthermore, the two glasses 8, 9 each have a different filtration layer, not shown in the figures. In this example, the filtration layer is fixed to the surface of the glasses 8 and 9, but it could be envisaged that said layer is inserted into the glasses 8, 9. The first glass 8 comprises a filtration layer capable of absorbing, or filtering, more than 80% of the light j visible; the yellow color being almost completely absorbed. The second glass 9 has a filtration layer capable of absorbing, or filtering, less than 20% of the visible light; the yellow color not being, or practically not, filtered by said glass.
Les couches de filtration des deux susdits verres sont obtenues par injection, par un revêtement de surface à chaud ou par une teinte prise dans la masse.The filtration layers of the two aforementioned glasses are obtained by injection, by a hot surface coating or by a shade taken in the mass.
Les diagrammes représentés sur les figures 3 etThe diagrams shown in Figures 3 and
4 illustrent approximativement les observations relevées quant au pourcentage absorbé, ou plus exactement non filtré, d'un rayon lumineux en fonction de la longueur d' onde.4 illustrate approximately the observations made as to the absorbed percentage, or more exactly unfiltered, of a light ray as a function of the wavelength.
Selon une possibilité offerte par l'invention, le dispositif visuel comprendra un miroir d'argent, appliqué sur la surface des verres grâce aux techniques bien connues de l'état de l'art. Ce miroir d'argent permet de conférer un effet esthétique à la paire de lunettes 1 en modifiant les couleurs, jaune et violette, de chacun des verres 8, 9, pour présenter des verres d'aspect argenté, ou gris. Par ailleurs, ce miroir d'argent permet également d'arrêter totalement les rayons UVA et UVB.According to one possibility offered by the invention, the visual device will include a silver mirror, applied to the surface of the glasses using techniques well known in the state of the art. This silver mirror makes it possible to impart an aesthetic effect to the pair of glasses 1 by modifying the colors, yellow and purple, of each of the glasses 8, 9, to present glasses of silvery, or gray appearance. In addition, this silver mirror also makes it possible to completely stop UVA and UVB rays.
Selon un mode d'exécution préféré de l'invention, la couche de filtration du premier verre 8 filtre 91% de la lumière visible et la couche de filtration du second verre 9 filtre 10% de la lumière visible. Ainsi, par exemple, un spectateur muni de lunettes comportant les verres 8, 9, selon l'invention pourra voir les images d'un film en couleur avec une impression saisissante de relief et/ou une augmentation marquée des profondeurs de champ. Le dispositif visuel ne nécessite donc aucune préparation préalable de l'image, de prise de vue, ni aucun traitement préalable du support de l'image. Ledit dispositif peut ainsi s'utiliser avec n'importe quelle image en couleurs, analogiques ou numériques, et étant projetées de manière classique.According to a preferred embodiment of the invention, the filtration layer of the first glass 8 filters 91% of the visible light and the filtration layer of the second glass 9 filters 10% of the visible light. Thus, for example, a spectator provided with glasses comprising the glasses 8, 9, according to the invention will be able to see the images of a film in color with a striking impression of relief and / or a marked increase in the depths of field. The visual device therefore does not require any prior preparation of the image, of shooting, or any prior processing of the support of the image. Said device can thus be used with any color image, analog or digital, and being projected in a conventional manner.
Par ailleurs, les couches de filtration des deux verres 8 et 9, ou lentilles, filtrent la totalité des Ultra Violet B ainsi que la quasi-totalité des Ultra Violet A.In addition, the filtration layers of the two glasses 8 and 9, or lenses, filter all of the Ultra Violet B as well as almost all of the Ultra Violet A.
En outre, le dispositif visuel selon l'invention pourra comprendre un système de détection antivol, inséré dans la monture, consistant par exemple en une bande magnétique insérée dans une monture de lunettes.In addition, the visual device according to the invention may comprise an anti-theft detection system, inserted in the frame, consisting for example of a magnetic strip inserted in a spectacle frame.
L'invention est décrite dans ce qui précède à titre d'exemple non limitatif. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet. The invention is described in the foregoing by way of nonlimiting example. It is understood that a person skilled in the art is able to carry out different variants of the invention without going beyond the scope of the patent.
