Description

"Procédé pour établir et mémoriser un motif scénigue et moyens pour la mise en oeuvre de ce procédé" "Method for establishing and memorizing a scenic motif and means for implementing this method"
La présente invention concerne un procédé pour établir et mémoriser un motif destiné à réaliser, après avoir été placé dans le faisceau lumineux d'un projecteur, une zone éclairée créant sur une scène notamment un décor lumineux.The present invention relates to a method for establishing and storing a pattern intended to produce, after being placed in the light beam of a projector, an illuminated area creating on a scene in particular a light setting.
De façon habituelle on fait appel le plus généralement à des plaques opaques à la lumière, comportant des plages ou zones transparentes destinées à laisser passer un faisceau lumineux uniquement à l'intérieur de ces plages ou zones. Dans le domaine scénique le décor lumineux est obtenu sur la scène en fonction de la forme et de 1'éclairement de ces zones transparentes qui sont de formes pré-établies. La présente invention fournit à l'utilisateur la possibilité de réaliser lui-même des plaques munies des motifs dont il a besoin pour le déroulement d'un spectacle, et ce proportionnellement à ce qui se passe sur la scène.Usually, use is generally made of plates opaque to light, comprising transparent areas or zones intended to allow a light beam to pass only within these areas or areas. In the scenic field, the light decoration is obtained on the stage as a function of the shape and the illumination of these transparent zones which are of pre-established shapes. The present invention provides the user with the possibility of making plates himself with the patterns he needs for the performance of a show, and this in proportion to what is happening on the stage.
Le procédé objet de la présente invention consiste à réaliser au moins un cliché d'une scène avec éventuellement les objets, décors, personnages et autres accessoires gui s'y trouvent et/ou à le faire apparaître sur écran en superposition sur un cliché de dessin obtenu par assistance d'ordinateur, à enregistrer et mémoriser ledit cliché, à réaliser, enregistrer et mémoriser des effets scéniques complémentaires et/ou supplémentaires destinés à se combiner par superposition aux premiers effets résultant -de l'enregistrement du premier cliché, et à réaliser les plaques supports destinées à la projection et comportant les données correspondant aux enregistrements effectués.The process which is the subject of the present invention consists in making at least one picture of a scene with possibly the objects, decorations, characters and other accessories which are there and / or making it appear on screen superimposed on a drawing picture. obtained by computer assistance, to record and memorize said photograph, to produce, record and memorize additional and / or additional scenic effects intended to be combined by superposition with the first effects resulting from the recording of the first photograph, and to produce the support plates intended for projection and containing the data corresponding to the recordings made.
De façon avantageuse, les effets scéniques complémentaires ou supplémentaires sont réalisés au moyen de dessins obtenus par ordinateur.Advantageously, the complementary or additional scenic effects are produced by means of drawings obtained by computer.
Quelle que soit la façon dont ces dessins ont été conçus leurs pourtours sont portés sur la plaque de verre destinée à la projection et enduite d'un revêtement opaque susceptible d'être découpé pour dégager les zones au travers desquelles on désire laisser passer la lumière.Whichever way these drawings were designed, their edges are carried on the glass plate intended for projection and coated with an opaque coating capable of being cut to clear the areas through which we want to let the light through.

Les composants et éléments constitutifs d'un appareil selon 1'invention ressortiront de la description faite ci-après dans le cas de son utilisation pour l'enregistrement d'un effet scénique désiré.The components and constituent elements of an apparatus according to the invention will emerge from the description given below in the case of its use for recording a desired scenic effect.
Un projecteur 12 illumine une scène 11 comportant ses décors, mobiliers et autres accessoires et sur laquelle peuvent se trouver des personnages, chacune de ces entités portant la même référence 10. L'appareil selon l'invention est disposé de manière gu'une image complète de cette scène dans son ensemble se forme sur une plaque de verre dépoli 4 par l'intermédiaire de l'objectif 1 du premier ensemble constitutif dit ensemble optique. La mise au point de cette image est assurée par un dispositif d'asservissement de type connu 9 et par un miroir à réflexion totale 2 disposé de préférence à 45°, ce miroir étant monté articulé et asservi en 25 pour permettre l'utilisation de l'appareil en projection comme on le verra ci- après. L'image formée en 4 est "lue" par une caméra-vidéo 6 et cette image fidèle est celle représentant exactement l'ensemble qui sera appréhendé par l'appareil (désigné par la référence générale 18) lorsque celui-ci sera utilisé comme appareil de projection de cette scène 11 et des objets et personnages 10 qui s'y trouvent.A projector 12 illuminates a scene 11 comprising its decorations, furniture and other accessories and on which characters can be found, each of these entities bearing the same reference 10. The apparatus according to the invention is arranged so as to provide a complete image of this scene as a whole is formed on a frosted glass plate 4 via the objective 1 of the first constitutive assembly called the optical assembly. The development of this image is ensured by a control device of known type 9 and by a total reflection mirror 2 preferably arranged at 45 °, this mirror being mounted articulated and controlled at 25 to allow the use of the 'apparatus in projection as will be seen below. The image formed in 4 is "read" by a video camera 6 and this faithful image is that representing exactly the assembly which will be apprehended by the apparatus (designated by the general reference 18) when the latter is used as apparatus of projection of this scene 11 and of the objects and characters 10 therein.
Cette image est envoyée de façon connue en soi dans le premier ordinateur 13 ou sur un écran vidéo de l'ensemble d'enregistrement-mémorisation pour être enregistrée d'une part numériquement et d'autre part visuellement sur l'écran 8 tout en étant répertoriée (toujours de façon connue en soi) par le clavier 15.This image is sent in a manner known per se to the first computer 13 or to a video screen of the recording-storage unit to be recorded on the one hand digitally and on the other hand visually on the screen 8 while being listed (always in a manner known per se) by the keyboard 15.
On notera que 1'image apparaissant sur cet écran 8 correspond fidèlement à celle de la scène 11 et des objets, accessoires et personnages qui s'y trouvent vus par un observateur placé à la fenêtre 3 de l'appareil de projection (figure 2) . Cette image est introduite dans 1•ordinateur 14 gérant un logiciel de DAO classique avec son clavier d'enregistrement graphique qui réalise les tracés correspondant à des effets complémentaires ou supplémentaires qui peuvent être visibles sur l'écran. Par superposition de l'image provenant d'une part de la caméra 6 et de l'image réalisée par le système DAO et transmis par l'ordinateur 14, on pourra ainsi se rendre compte de visu de l'effet qui pourra être obtenu par projection sur la scène d'une telle image lorsque celle-ci sera reproduite sur un support approprié et notamment sur une plaque. On notera, en se référant au montage schématisé à la figure 3 que la caméra 6 ayant le point de vue de la fenêtre de projection 3 peut être connectée directement sur l'écran 8 en superposition avec les données vidéo fournies par l'ordinateur 14. On comprend que l'on pourra ainsi stocker etIt will be noted that the image appearing on this screen 8 corresponds faithfully to that of scene 11 and of the objects, accessories and characters therein seen by an observer placed at the window 3 of the projection device (FIG. 2) . This image is introduced in 1 • computer 14 managing a conventional CAD software with its keyboard of graphic recording which carries out the plots corresponding to additional or additional effects which may be visible on the screen. By superimposing the image originating on the one hand from the camera 6 and the image produced by the CAD system and transmitted by the computer 14, it will thus be possible to realize firsthand the effect which may be obtained by projection on the scene of such an image when it is reproduced on an appropriate medium and in particular on a plate. It will be noted, with reference to the assembly shown diagrammatically in FIG. 3, that the camera 6 having the point of view of the projection window 3 can be connected directly to the screen 8 in superposition with the video data supplied by the computer 14. We understand that we will be able to store and
"répertorier" tous les effets scéniques désirés et recherchés."list" all the desired and sought after scenic effects.
En effet, une fois la phase d'enregistrement effectuée comme il vient d'être décrit, c'est-à-dire après que l'image de la scène 11, et de ses décors et personnages 10, ait été transmise à l'ordinateur 13 et enregistrée et après avoir conçu les motifs voulus et les avoir tracés par DAO en fonction de l'image enregistrée provenant de la caméra 6, lesdits motifs sont repris par tout moyen approprié connu en soi sur une plaque de verre enduite d'un revêtement opaque de préférence en matière plastique.Indeed, once the recording phase has been carried out as described above, that is to say after the image of the scene 11, and of its decorations and characters 10, has been transmitted to the computer 13 and recorded and after having designed the desired patterns and having traced them by CAD according to the recorded image coming from the camera 6, said patterns are taken up by any suitable means known per se on a glass plate coated with a opaque coating, preferably made of plastic.
La ou les zones au travers desquelles on désire laisser passer la lumière sont enlevées manuellement à l'aide d'un outil approprié. Du reste toute cette opération peut être réalisée aussi au moyen d'appareils appropriés que l'on trouve actuellement sur le marché. Ce stade du procédé est schématisé en 17.The area (s) through which it is desired to let the light pass are removed manually using an appropriate tool. Besides, all this operation can also be carried out by means of suitable devices which are currently found on the market. This stage of the process is shown schematically in 17.
On pourra par exemple procéder comme schématisé à la figure 4. La plaque de verre 108 revêtue de son revêtement plastique opaque 109 est montée sur un châssis de manière à pouvoir entrer en contact avec une lame tournante 107 portée par une tête 112 susceptible de déplacement suivant 104 - 105 (coordonnées X - Y) en fonction des données fournies par 1'ordinateur DAO proportionnellement à 1'image donnée par la caméra 6. Selon une technique en soi connue, un moteur 102 commande la rotation de la lame 107 et la position à chaque instant, en cours de travail, est donnée par un codeur de position 103 de façon à réaliser une entaille dans le revêtement 109, suivant par exemple, le contour 106. Un électroaimant 110 commande la translation de la tête 112 dans le sens de 101 si l'on ne désire pas réaliser d'entaille, le codeur de position pouvant jouer ce rôle de commande. Grâce à un outil pointu 111 on peut alors dégager manuellement la zone de contour 106, zone au travers de laquelle on désire laisser passer ultérieurement la lumière.We can for example proceed as shown schematically in Figure 4. The glass plate 108 coated with its opaque plastic coating 109 is mounted on a frame so as to be able to come into contact with a rotating blade 107 carried by a head 112 capable of following displacement 104 - 105 (X - Y coordinates) according to the data provided by The DAO computer in proportion to the image given by the camera 6. According to a technique known per se, a motor 102 controls the rotation of the blade 107 and the position at all times, during work, is given by an encoder position 103 so as to make a notch in the covering 109, along for example the contour 106. An electromagnet 110 controls the translation of the head 112 in the direction of 101 if it is not desired to make a notch, the encoder position that can play this control role. Thanks to a pointed tool 111, it is then possible to manually release the contour zone 106, zone through which it is desired to let the light pass later.
On se sert alors de l'appareil selon l'invention pour procéder à la projection des motifs réalisés sur lesdites plaques et pour obtenir l'effet scénique désiré.The apparatus according to the invention is then used to project the patterns produced on said plates and to obtain the desired scenic effect.
En se référant à la figure 2 cette projection se fait de la façon suivante :Referring to Figure 2, this projection is done as follows:
Le miroir 2 est escamoté par le dispositif d'asservissement 25 qui fait pivoter ce miroir vers le haut autour de son axe d'articulation de façon à ne pas faire obstacle à la lumière émanant de la lampe 21 (située au foyer de son miroir sphérique 20) en passant par le condenseur 22-23 éclairant la fenêtre de projection 3.The mirror 2 is retracted by the servo device 25 which pivots this mirror upwards around its axis of articulation so as not to obstruct the light emanating from the lamp 21 (located at the focal point of its spherical mirror 20) passing through the condenser 22-23 lighting the projection window 3.
Les plaques qui ont été réalisées comme décrit précédemment sont introduites dans cette fenêtre et les motifs qu'elles présentent sont ainsi projetés sur la scène 11 où se trouvent décors, accessoires et personnages 10. On obtient ainsi la projection de motifs lumineux proportionnels et ce en fonction de ces objets, décors ou personnages. On comprendra aisément que, sur une même scène, on pourra utiliser plusieurs appareils diversement disposés (de face, latéralement, de haut etc.), chaque appareil étant du type selon l'invention. Dans ce cas chaque caméra de chaque projecteur devant envoyer à l'ordinateur 13 son propre point de vue, les traitements par DAO seront indépendants les uns des autres. De même plusieurs plaques de verre réalisées selon l'invention pourront être utilisées sur chaque appareil et présentées dans les fenêtres de projection par l'intermédiaire de dispositifs automatiques et/ou programmables de types bien connus.The plates which have been produced as described above are introduced into this window and the patterns which they present are thus projected onto the scene 11 where there are decorations, accessories and figures 10. The projection of proportional light patterns is thereby obtained. function of these objects, decorations or characters. It will be readily understood that, on the same stage, it is possible to use several devices that are variously arranged (front, side, top, etc.), each device being of the type according to the invention. In this case, each camera of each projector having to send to the computer 13 its own point of view, the treatments by CAD will be independent of each other. Likewise, several glass plates produced according to the invention can be used on each device and presented in the projection windows by means of automatic and / or programmable devices of well known types.
On signalera par ailleurs que 1'invention permet la création avec un système DAO de dessins de lumière sur une scène vide sans personnages, ni objets, ni décors comme, par exemple la réalisation d'un dessin de dallage (damier) sur un sol ou celui d'un décor mural avec effet de perspective avec point de fuite, l'effet étant d'autant plus sensible que l'appareil de projection est judicieusement disposé et placé par rapport à la scène.It should also be noted that the invention allows the creation with a CAD system of light drawings on an empty stage without characters, objects or decorations such as, for example the production of a paving pattern (checkerboard) on a floor or that of a wall decoration with perspective effect with vanishing point, the effect being all the more sensitive as the projection apparatus is judiciously arranged and placed in relation to the scene.
On notera aussi que ces effets de lumière pourront être accentués ou adoucis suivant l'intensité de 1'éclaire ent délivré par la projection. Aussi on pourra prévoir sur l'appareil de projection un variateur de lumière 19 (Fig. 2) commandé par un équipement annexe permettant d'intensifier ou d'abaisser le flux lumineux donnant ainsi des effets supplémentaires combinés à ceux que l'on peut obtenir en faisant appel à des projecteurs avec filtres de couleurs etc.. II va du reste de soi que la présente invention n'a été décrite qu'à titre purement explicatif et nullement limitatif et que toute modification utile au niveau des équivalences pourra y être apportée sans sortir de son cadre.It will also be noted that these light effects may be accentuated or softened depending on the intensity of the light provided by the projection. Also, a light dimmer 19 (Fig. 2) can be provided on the projection apparatus, controlled by additional equipment making it possible to intensify or lower the light flux, thus giving additional effects combined with those which can be obtained. by using projectors with color filters, etc. It goes without saying that the present invention has only been described for explanatory purposes and is in no way limitative and that any useful modification in terms of equivalences may be made. without going beyond its framework.
L'ensemble des organes de commande 7, 25, 9 et 19 est avantageusement incorporé dans un pupitre de contrôle annexe. The set of control members 7, 25, 9 and 19 is advantageously incorporated in an annex control console.
