  • recording, transmitting, recording, receiving and reproducing devices are drawn with a transmission link, as they are used in a conventional television transmission device.
  • a switching device is provided in the recording device, which enables the switching of the video signals coming from the cameras 3, 4.
  • a switchover device is provided in the television camera, which alternately passes the light rays coming through lenses onto a single scanning surface of the camera by means of a lens and mirror system, which is otherwise also used in stereo microscopes.
  • the recorded images can be recorded, as in the case of conventional television images, by means of a recording device, by means of a transmission device directly after the recording, or indirectly as a recording via a wireless or wired transmission link and transmitted be received by a receiving device.
  • the design of the display device depends on whether the images intended for the left and right eyes of the viewer are transmitted in series or in parallel.
  • a switchover device is also provided in the playback device in order to separate the serially transmitted images from one another. Both switchover devices, both those in the recording device and those in the reproduction device, are switched each time after a full picture intended for one eye has run off to the picture intended for the other eye. In the television systems which use two fields for one frame, the switchover occurs after two recorded or reproduced fields.
  • FIG. 3 shows a display device in which, in a picture tube 6, electron beams, which are generated by two beam generation systems 7, 8, are projected onto a screen 11 by two deflection systems 9, 10.
  • FIG. 5 shows a display device in which the two television images intended for the left and right eyes are projected onto a screen 28 by two television image projectors 26, 27.
  • the image intended for the left eye is depicted on the left half and the image intended for the right eye on the right half of the canvas 28, the two images adjoining each other on the central perpendicular of the canvas 28.

  • the television image projectors 26, 27 can be pivoted about horizontal axes 18, 19 Spindles 14, 15, which are driven by electric motors 16, 17, are used to adjust the image size, and spindle nuts are arranged on the television image projectors 26, 27, so that the projectors can be moved in the direction of the projection, both the swiveling movement and the Movement movement can be provided with a remote control.
  • the beam generation systems 30, 32 with the associated deflection units 33, 34 each sit on a carriage 44 (FIG. 8). These carriages can be pushed back and forth by spindles 40, 41.
  • the spindles 40, 41 are driven by electric motors 38 and 39, respectively. Pushing the beam generation systems back and forth allows the image size to be adapted to the sea properties of the viewer. Both the swiveling movement and the displacement movement can be remotely controlled by the viewer.
  • buttons 45 and a pair of buttons 46 are provided with which the pivoting movement or the image size setting can be operated remotely.

Abstract

Deux caméras de télévision (3, 4) sont disposées de manière que la distance (d) qui les sépare correspond à la distance moyenne entre les yeux de l'homme. Ainsi on obtient deux images, l'une pour l'oeil gauche et l'autre pour l'oeil droit ou vice-versa. Ces images sont envoyées séparément aux yeux qui leur correspondent ce qui donne au spectateur la sensation d'une image tridimensionnelle. Le procédé et le dispositif pour sa mise en oeuvre conviennent pour la télévision en noir et blanc ou en couleurs.
