Monoscopic and stereoscopic television apparatus Monoskopisk och stereoskopisk televisionsapparat

The invention relates to a television device for displaying identical monoscopic or different monoscopic (stereoscopic) images in pairs, possibly together with sound, comprising at least one display unit suitably comprising optical means for displaying images to each human eye, the display units being connected and fixed to a frame fitted to be placed close enough to the eyes so that each image is displayed to each eye separately, the television set further comprising playback means for receiving and / or forming and sharing said images, one image for each display unit.

It is essentially a device for receiving and reproducing monoscopic and stereoscopic images and sound transmitted from a television transmitter or a local transmitting, reproducing or image developing apparatus.

What all previously known television receivers have: ‘·· in common is that they are designed to be placed at a distance f’: from the human eye and not to be placed, installed or: used directly by the eyes themselves. This applies to television receivers for both monoscopic and stereoscopic images. For receiving and reproducing stereoscopic television images, reference is made, for example, to U.S. Patent No. 4,310,849. According to this patent publication, stereoscopic images are transmitted to the eyes via two fiber optic bundles from a television receiver. The television receiver receiving and reproducing the images, in turn, is placed away from the eyes, i.e. outside the headphones carrying the fiber optic bundle, which is mandatory. add lenses close to the eyes.

According to the invention, the television receiver itself can be placed, installed or supported right in front of the eyes. This in turn leads to more flexible use of the receiver both outdoors and indoors and also opens up the possibility for several types of applications. At the same time, maximum view is achieved.

In addition, when reproducing monoscopic television images, the effect of these will be greatly improved by the fact that a certain degree of depth effect can be achieved, thus perceiving a certain distance from the visible position of the image.

According to the invention, this is achieved in that the reproduction means together with the display units are built into one of the aforementioned frames. Thus, two specially designed, preferably liquid crystal-based display devices with highly integrated circuits are provided for receiving (tuning part), forming (synchronizing / adjusting, etc.) and distributing (video part) an image, one image for each display, i.e. one image left eye and one image for the right eye. The images are in pairs, two identical or two different monoscopic images. In addition, a magnifying glass / lens is attached to the front of each display device, and the complete device is assembled in a frame side by side so that it can be placed in a glass-like or double-glazed-like manner (without spectacle frames) / over the back of the nose close to both eyes, that the left and right eyes see only their corresponding image. To maximize the monoscopic or stereoscopic image for both eyes, the distance between the lenses and the distance between the lenses and the display devices are adjustable.

When receiving monoscopic television images, the same monoscopic image is transmitted to both display devices by causing the highly integrated circuits to receive, form and share the same monoscopic image on each of the respective display devices or e.g. by allowing a second video portion to transmit the same monoscope image to both displays.

Images can be either color or black and white.

The device is battery operated. The front of the instrument can also be a solar panel. Depending on the amount of light available, this panel supplies power to operate the instrument and, if desired, to charge the batteries. The batteries begin to supply power when there is not enough light available for the cell panel.

As an alternative to liquid crystal-based display devices, but still as a less advantageous solution, e.g. CRT- or LED-type display devices or fiber optic bundles can be used. Alternatively, in some types of instruments, a single display device and a conventional mirror fit in front of the eyes may be used.

There may be different types and designs of spectacle frames in the form of spectacles or double glazing.

.. In a simpler version of a television set. the tuning part can be omitted. This can be the case, for example, when using cables to portable or fixed monoscopic and stereoscopic video program players or computer devices that develop an image. If desired, the tuning section can also be placed in the recording / display device. Video programs or images can be transmitted to multiple pairs of spectacles or double glazing, if desired.

The technique by which television images are received and. i is transmitted to a specially designed liquid crystal display device via highly integrated circuits. in a product (Television Watch) from the business name Seiko (Japan), in which case, however, the television image (and sound) is transmitted to the wristwatch, and also in flat so-called on pocket TVs supplied by Seiko and Casio. However, these cannot be placed, installed, or supported directly with both eyes.

Figures 1 and 2 show diagrammatically the arrangement of the two display devices (1, 2) and the lens (3, 4) in the spectacle frame (5, 6), which is visible from the rear and from the front, respectively. The drawings do not show highly integrated circuits and other parts and construction of the instrument.
