FR2822392A1 - Real time animated system music synchronised having sound activating surface placed objects and objects movement filmed with movement proportional sound intensity. - Google Patents

Abstract

The animated images system has an audio amplifier (2) receiving a signal (1). A loudspeaker (3) is connected to the amplifier and has a surface on which small objects (5) are placed. Movement of the objects is determined by loudspeaker intensity. The movement is filmed by a camera and the video signal (7) can then be modified, recorded or broadcast.

Description

<Desc / Clms Page number 1>

 The present invention relates to a device for real-time moving images which will be visually synchronized to the rhythm of any music or audio event.

etc.). Synchronizing audiovisual images to a musical rhythm in real time generally uses advanced technologies such as certain computer programs or special effect generators. These fairly high cost systems do not for the most part make it possible to visually calibrate images automatically on a rhythm and are in any case dependent on a bank of images stored on different media (video cassettes, D.V , D., CD Rom, hard disks

etc.).

The device according to the invention makes it possible to create and produce visuals synchronized with music without image bank or computer, all in real time. It comprises according to the invention the association of several technological instruments: an audio amplifier with volume control connected to a loudspeaker, a reception surface of fairly fine thickness and light weight on which small objects light enough to move are placed, a camera. By acting on the volume of the amplifier, the diaphragm of the loudspeaker vibrates with more or less great intensity, which causes a displacement of air which can make vibrate the reception surface on which are placed the small objects which are put in movement to the rhythm of vibrations and therefore of music. A camera films moving objects, the video signal from the camera can then be read on a control monitor.

 According to particular embodiments: the use of an audio equalizer will act on the movements and displacements of objects. the surface used on the loudspeaker can be more or less flat and made of different materials: paper, cardboard, aluminum, plastic, fabrics, etc., The objects placed on the surface can be replaced by liquids or heavy gases at condition to adapt the receiving surface (by adding edges for example to contain a liquid).

 The image captured by the camera can be processed on a special effects control before being recorded and / or broadcast live on

 different media: televisions, monitors, video projectors and all systems for transporting an animated image.

The attached drawing illustrates the invention:
With reference to this drawing, the device comprises on the one hand an audio amplifier (2) receiving an audio signal (1), a loudspeaker (3) connected to the amplifier (2), a surface of reception (4) placed on the loudspeaker and small objects (5) placed on the reception surface (4) and on the other hand a camera (6) which closely films the movements and displacements of small objects ( 5), the image seen by the camera is represented in (7).

 According to a variant not illustrated, the reception surface and the loudspeaker may be more or less inclined, or even vertically.

According to a variant not illustrated, the objects can move freely or even be attached to a wire or any other fixing system,
According to a variant not illustrated, the receiving surface (4) is optional, the objects are then placed on the membrane.

According to a variant not illustrated, the receiving surface (4) is optional, it is then possible to use the displacement of air caused by the vibration of the diaphragm of the loudspeaker to set in motion (3) objects, materials or gases,
The device of the invention is particularly intended for the creation and dissemination of animated visuals in particular on musical performances, for the production of musical videograms, for the creation of television coverings and by extension to any other audiovisual activity.

Claims (1)

CLAIM Device for producing live, rhythmic images of music in real time, characterized in that it comprises an audio amplifier (2) receiving a signal (1), a loudspeaker (3) connected to the amplifier (2), a receiving surface (4) on which small objects are placed (5), By increasing the sound level on the amplifier, we increase the intensity of the energy produced by the vibration of the upper membrane -speaker (2) and therefore the intensity of the reception surface (3) which causes the synchronized movement of the objects (4), a camera films the objects (4), the video signal (7) of the camera can then be changed. recorded or broadcast.
