Definitions

• the invention relates to a television device for reception and reproduc ⁇ tion of monoscopic and stereoscopic images and sound sent from a tele ⁇ vision transmitter or from a local transmitter-, playback- or image generating equipment.
• Co ⁇ rnon for all previously known television receivers is that they are constructed for remote placement in relation to the human eyes, and not for placing, mounting or carrying right up to the eyes themselves. This applies to television receivers both for monoscopic and stereoscopic images.
• the stereoscopic images are transmitted to the eyes via two fiber optic bundles from the television receiver.
• the television, receiver itself, which receives and reproduces the images, is, however, remotely placed in relation to the eyes. In other words, outside the headset holding the fiber optic bundles, with the necessary addition of lenses, close to the eyes.
• the television receiver itself can be placed, mounted or carried right up to the eyes themselves. This again makes it more flexible in use, both outdoors and indoors, and also opens up the possibility for several types of applications. At the same time one achieves maximum area of vision. When reproducing monoscopic television images the effect for these will, in addition, be considerably increased due to the possibility of a certain amount of depth effect, i.e. one experiences a certain distance to the visual placement of the image.
• this is brought about by supplying two speci ⁇ fically designed displays, preferably based on liquid crystals, with high integrated circuits for reception (tuner part), building up (syn ⁇ chronizing/control etc.) and distribution (video part) of one image for each display, i.e. one image for the left eye and one image for the right eye.
• the images are in pairs, two identical or two different mono ⁇ scopic images.
• a magnifying glass/lens is fixed in front of each display and the complete device is assembled in a frame, side by side in such a way that it can be placed as a pair of spectacles binoculars (without spectacle arm) over the bridge of the nose close to both eyes, so that the left and right eye sees only its corresponding image.
• the distance between the lenses and the distance from the lenses to the displays is adjustable.
• the same monoscopic image is transmitted to both displays by allowing the high integrated circuits to receive, build up and distribute the same monoscopic image to each of its corresponding displays, or, for example, by allowing one of the video parts to transmit the same monoscopic image to both displays.
• the images can be either in colour or in black and white.
• the apparatus is charged by batteries.
• the front of the apparatus may also consist of a solarcell panel. Depending on the amount of light available, it supplies power for operation of the apparatus and, if desired, for loading the batteries.
• the batteries take over when insuf ⁇ ficient light is available to the solarcell panel.
• displays based on liquid crystals
• displays of the type for example, CRT or LED may be used, or fiber optic bundles.
• only one display with a traditional mirror arrangement in front of the eyes may be used as an alternative.
• the frame for a television receiver in a spectacle or binocular form can be of various types and design.
• Signals for images to the left and right eye may be received on the same or separate VHF and/or UHF channels or transmitter frequencies.
• Images and sound may be transmitted via the same VHF and/or UHF channels or transmitter frequencies. Sound is transmitted directly or via a set of earphones, for example, via a conductor through the spectacle arms.
• the tuner part can be omitted. This can occur when using cables to, for example, portable/ stationary playback equipment for monoscopic and stereoscopic video programmes or to computer equipment for image generating. A tuner part can also, if wished, be placed in a recording/playback equipment. Video programmes or images can, if desired, be transmitted to several pairs of spectacles or binoculars.
• Figure 1 and 2 schematically show an example of the placing of two dis ⁇ plays (1,2) and lenses (3,4) in a spectacle frame (5,6) seen from behind and from above respectively.
• the h.igh integrated circuits and the other parts and design of the device are not shown on the drawings.
