Abstract

The invention relates to a device enabling complex camera movements to be performed which are impossible to produce manually. The apparatus consists of a movable carriage A, an articulated arm B and a pan head C; the whole unit is actuated by stepping motors programmed by microcomputers, as well as focusing rings and rings for adjusting the zoom for filming. By virtue of the video sight E and the computer D, F, the various frames constituting a shot are stored in memory during a rehearsal. Upon recording, the program is executed in real time, with the same accuracy, as many times as required by the director (directing crew). The device according to the invention is intended particularly for productions in which it is desired to perform sophisticated camera movements and trick shots directly.

Description

La présente invention concerne un système de prises de vues cinéma-vidéo qui permet de réaliser l'enchainement avec souplesse et précision de mouvements complexes de caméra. The present invention relates to a cinema-video shooting system which makes it possible to carry out the sequence with flexibility and precision of complex camera movements.

Traditionnellement, le déplacement de l'axe optique de prise de vue des caméras est effectué par des systèmes contrôlés manuellement ce qui entraîne une certaine irrégularité entre les différentes prises d'un même plan et rend incertaine la mise au point de mouvements très complexes. Traditionally, the movement of the camera's optical axis of shooting is carried out by manually controlled systems, which results in a certain irregularity between the different shots of the same plane and makes the development of very complex movements uncertain.

Le dispositif selon l'invention permet de remédier à ces inconvénients. Il met en oeuvre une plate-forme, support de caméra, entièrement automatisée par sept moteurs pas à pas asservis par micro-ordinateurs. The device according to the invention overcomes these drawbacks. It implements a platform, camera support, fully automated by seven stepper motors controlled by microcomputers.

Cette plate-forme est composée
- d'un chariot (Fig. I nO A) rendu mobile par des roues motrices actionnées par le moteur (V) et dirigé par le moteur (VI),
- d'un bras articulé (Fig. I nO B) permettant la montée et la descente grâce à des vérins pneumatiques contrôlés par le moteur (IV),
- la tête panoramique (Fig. I nO C) est mobile en site et azimut par les moteurs (II) et (III),
- enfin, la bague des focales du zoom de prises de vues se déplace à l'aide du moteur (I).This platform is composed
- a carriage (Fig. I nO A) made mobile by drive wheels actuated by the engine (V) and steered by the engine (VI),
- an articulated arm (Fig. I nO B) allowing the ascent and descent thanks to pneumatic cylinders controlled by the motor (IV),
- the panoramic head (Fig. I nO C) is movable in elevation and azimuth by the motors (II) and (III),
- finally, the focal ring of the shooting zoom moves with the help of the motor (I).

Cette unité de six moteurs est programmée par le calculateur(D). This unit of six motors is programmed by the computer (D).

Le moteur supplémentaire (I bis) actionne la mise au point focal de l'objectif. The additional motor (I bis) activates the focal focusing of the lens.

Le principe de fonctionnement est simple et rapide, les moteurs de l'appareil sont programmables pendant une répétition par la mise en mémoire des différents cadres et points focaux qui composent un plan. Ces moteurs fonctionnent en mode synchrone et assynchrone, en temps réel (compté en seconde et fraction de 1/25") ou image par image. A la prise de vue, la plate-forme exécute fidèlement les ordres du programme en reliant par des mouvements rectilignes ou courbes les différentes positions mises en mémoire, ceci autant de fois que la mise en scène le nécessite. The principle of operation is simple and fast, the motors of the device are programmable during a repetition by memorizing the different frames and focal points that make up a plan. These motors operate in synchronous and asynchronous mode, in real time (counted in seconds and fraction of 1/25 ") or image by image. When shooting, the platform faithfully executes the orders of the program by linking by movements rectilinear or curved the different positions stored in memory, this as many times as the staging requires.

Un système agissant sur la base temps permet d'ajuster, en cours de prises de vues, la vitesse de déroulement du programme aux déplacements des acteurs. A time-based system makes it possible to adjust the speed of the program during the shots during the shots of the actors.

La visée s'effectue avec les -caméras équipées de la visée vidéo grâce au moniteur (E), l'ensemble des contrôles informatiques est rassemblé sur l'écran (F), la plate-forme dispose d'une commande à distance et d'un magnétoscope pour le visionnage immédiat. La partie électronique (G) d'alimentation des moteurs est modulaire et des butées électriques protègent les moteurs dans les différents axes.  The aiming is carried out with the cameras equipped with the video aiming thanks to the monitor (E), all the computer controls are gathered on the screen (F), the platform has a remote control and '' a video recorder for immediate viewing. The electronic part (G) for supplying the motors is modular and electrical stops protect the motors in the different axes.

La présente invention constitue en fait un nouveau système de prises de vues, appelé AUTOCAM, qui aura des possibilités inconnues actuellement, en particulier pour certains effets spéciaux (zoom et polarisation compensés, enchaînés dans le mouvement, longs téléobjectifs, image par image). The present invention in fact constitutes a new shooting system, called AUTOCAM, which will have possibilities currently unknown, in particular for certain special effects (compensated zoom and polarization, chained in motion, long telephoto lenses, image by image).

Par son faible encombrement, la plate-forme est utilisable en décors naturels comme en studio (pour le son synchrone, mettre un filtre "passe haut" 20000 Hz sur l'enregistreur). By its small footprint, the platform can be used in natural settings as in the studio (for synchronous sound, put a "high pass" filter 20,000 Hz on the recorder).

Bien évidemment, cet appareil n'est pas utilisable en reportage et en général lors de prises de vues improvisées. Obviously, this device is not usable in reporting and in general during improvised shots.

Au service des responsables de l'image, l'AUTOCAM trouve sa place dans les productions désireuses de l'utiliser pour ses performances nouvelles dans le domaine des mouvements de caméras sophistiqués et des trucages directs.  At the service of image managers, AUTOCAM finds its place in productions wishing to use it for its new performances in the field of sophisticated camera movements and direct special effects.
