Definitions

  • the invention relates to a method and a device for converting modulated and acoustically reproducible electrical signals into moving images.
  • discotheques or at outdoor events it is common to play music from sound carriers or to produce live music on a stage and, in addition, to run moving pictures on large screens or projection screens.
  • the visual performances can be natural spectacles, sporting events or feature film scenes. As a rule, they have nothing to do with the music being played, but are supposed to entertain and stimulate the visitors on a second level.
  • a sound signal is input into a microphone Frequency band filter fed. Its output channels become a multi-channel Input module supplied that a multiplexer and an analog-digital converter includes. The signal is passed to a microcomputer to be there calculate image-characterizing shape and color data. These become one Video signal generator supplied, which has the task of consisting of colored images Create surfaces and lines and change them quickly.
  • the system uses a complex electronic system to generate the image patterns Circuit that first filters and digitizes audio signals and then using a Converts combination of software and hardware into visual signals.
  • a light bulb serves as the light source, the light of which is passed through a rotatable color filter and a rotatable optical converter made of glass fibers.
  • the image patterns generated in this way are alienated with the help of a prism and thrown onto a canvas using the imaging optics. Because of the necessary high light output and undesirable heat emission, thermal insulation and a cooling device are required.
  • a synchronization with electrical signals (e.g. music) is not provided.
  • the invention has for its object to provide a form of performance, the music. Singing or other acoustic signals are converted into sound images synchronously in order to achieve this To deepen the sound experience through visual impressions.
  • the signal source is an oscilloscope or feeds a monitor that its image consisting of wave trains over alienating optical aids is recorded by a video camera and that this camera is a large screen projector, a monitor, a television or one Laser imager feeds.
  • a collecting lens can be used as an alienating optical aid, which lens must be arranged at a certain distance between the screen and the camera.
  • Even more striking effects can be achieved by several mirrors arranged at an acute angle to each other, which practically represent a kaleidoscope without its own picture elements.
  • the mirrors represent a truncated pyramid.
  • Fig. 1 denotes a signal source with two channels, which feed an oscilloscope 2 as an image generator.
  • the curves of the screen image are recorded by a video camera 3.
  • a lens 4 is arranged in the beam path between the oscilloscope and the camera and specifically alienates the oscilloscope image.
  • the camera signals are fed via an image line 5 to an image display device 6 - here a video projector.
  • Television sets, computer monitors or laser sky recorders can also be used for image reproduction.
  • a CD player or any multi-channel player can be used as the signal source serve.
  • Microphone amplifiers can also be used to transmit live music be used.
  • FIG. 2a shows on the right two parallel straight lines on the oscilloscope screen and on the left the associated image, alienated by the lens 4, which the camera 3 records and which is thrown onto a screen with the image display device 6.
  • the image in Fig. 2a shows an outer circle in which there are two ellipsoid. move deformed rings.
  • a sine curve is given in Fig. 2b, it arises in Fig. 2b left an irregular, different wide band that penetrates the enveloping circle diagonally.
  • the pictures are only static examples and cannot hint at the effect of the figures moving in the rhythm of the sound.
  • the signal source 1 is in turn followed by an oscilloscope 2.
  • a conical kaleidoscope 7 is arranged between it and the camera 3. His mirrors, which are conically arranged at a certain angle, reflect the curves that appear on the screen in such a way that imaginative polygonal figures emerge in the basic pattern, which change simultaneously with pitch and amplitude.
  • Figures 4a and b show such figures.
  • 4a shows on the left two parallel, straight lines on the oscilloscope, that is to say baselines with the amplitude Zero".
  • the generated image in Fig. 4a right consists of regularly arranged double hexagons, the size of which increases from the inside out. In the center there are shadowy triangles. If, according to Fig. 4b, the signal transmitter emits a sound mixture on one channel and a sine line on the other channel, I will see a complicated pattern of rotationally symmetrical figures on the screen, which here resemble six-jet flowers.
  • the base is an equilateral triangle with sides a, b, c.
  • the body as a whole is a three-sided truncated pyramid.
  • the smaller triangular opening is assigned to the image generator, i.e. the oscilloscope, the larger of the video camera.
  • kaleidoscope 9 consisting of five mirrors, which is also designed as a truncated pyramid. All five tapered mirrors form the same angle. An internally mirrored hollow truncated cone would also be possible as an alienating optical aid.
  • FIG. 7 shows how the oscilloscope 2 and the video camera 3 can be assigned to one another when a lens 4 is used to alienate the signals.
  • the parts 2 and 3 are connected to one another by guide tubes 10 and 11, the position of the lens 4, as is customary in optical devices, being adaptable by tube adjustment or fine adjustment.
  • Fig. 8 is a corresponding arrangement with kaleidoscope 7. In this form there is a large overall length. In order to develop a compact, handy device, it is advantageous to use deflecting mirrors or deflecting prisms.
  • FIG. 9 shows such a solution with a kaleidoscope 7, which is placed in front of the video camera 3.
  • Two mirrors 12, 13 deflect the light beams through 90 ° each.
  • the lens 4 In between is the lens 4 as an additional element for changing the image.
  • Fig. 10 video camera 3 and oscilloscope 2 with mirrors 12, 13 and lens 4 are housed in a confined space.
  • the mirrors can be replaced by prisms.
  • the devices mentioned are housed in a protective housing to prevent extraneous light influences.
  • a converging lens 4 was used. Diffusing lenses or faceted lenses are also conceivable.
  • the lens or the lens system is arranged in the reversal point or in the blur area.
  • the image signal from the camera can be looped through directly to a television set or image projector or can also be recorded.
  • the recording media are digital or analog, depending on your preference.
  • the video camera can also be replaced by another electronic recording system.
  • the described device for converting signals into moving pictures is very well suited to be used in discotheques, restaurants, other event rooms or open-air stages in order to underscore and visually complement live or sound carrier performances.
  • the image and sound appear simultaneously, that the sounds recorded with the ears can also be seen to a certain extent. This creates a multimedia, intensive music experience in the minds of those present.
