Abstract

The present invention relates to a stereo-television scheme. According to the principle of stereoscopic vision production of people, said invention makes an improvement on the TV broadcasting and reception so as to produce lifelike stereo effect on the TV, in which its image stereovision treatment device uses the principle of light reflection to treat TV image so as to obtain stereovision effect. Its structure is simple, cost is low and its application is extensive. It also can be used for enjoying stereophotographic works and computer stereo picture.

Description

Stereo TV scheme

The present invention relates to the broadcast of three-dimensional television and the generation of TV stereo image.Its objective is common TV is suitably improved to reach stereoscopic visual effect.

When people saw thing, some subtle difference of the information of two acquisitions, cerebral cortex were distinguished these information and difference thereof, and have been produced the shape of the object of looking, the three-dimensional notion of size.

By this principle, we can propose the solution thinking of stereoscopic TV, that is: during shooting, take synchronously from two suitable angles, note this two parts information respectively by record equipment (video tape or cinefilm), after televising, by television receiver two parts information is sent into a left eye and right eye respectively, can be reduced into stereo image true to nature.

Three-dimensional film also designs according to this principle, the means of its realization are to have adopted polarised light, and after people put on the glasses that polarizer is housed, the image of showing in the screen was polarized sheet and filters, that part of information that every eye is only seen should see, stereoeffect then is reduced.

Present television set still can not reach this effect, and promptly a screen produces two kinds of different effects, and these two kinds of images can be received by right and left eyes respectively.For addressing this problem, the spy is the present invention.

The present invention realizes like this, take in two angles of taking the photograph object respectively by two complete equipments, the information that obtains is broadcasted with two channels, receiving terminal broadcasts this two group of pictures (adopt two television sets or design novel double screen television set), uses a kind of imaging stereo processing unit can produce stereoeffect.

Below with reference to the accompanying drawings, the operation principle to this device and stereoscopic TV describes in detail.

Figure one is the structural representation when taking light reflection mirror.

Figure two is the structural representations when adopting optical fiber.

Shown in figure one, television image A and B have broadcasted three-dimensional left figure and right figure.1,2,3,4 is respectively four light reflection mirrors (flat glass speculum or total reflection prism etc.) that use in this device.Image A enters 2 through 1, be reflected into left eye by 2, image B enters 4 through 3, by 4 the reflection enter right eye, people have seen the virtual image of A and B respectively from 2 and 4, these two virtual images all left former the position, adjust these four speculums and angle, the virtual image of A, B overlaps at a place, and as shown in phantom in FIG., at this moment people produce stereoscopic visual effect.

As shown in Figure 2, the A image enters left eye through fibre-optic bundle a, and the B image enters right eye through fibre-optic bundle b, adjusts the direction of fibre bundle by the eye end, can form the A that coincides with a place, the virtual image of B equally, produces stereoeffect.

This device may be used solely to appreciate the artistic work of other form, and as photographic work, except that photographic work was still life, its principle was identical with stereoscopic TV.

Can also be used to appreciating the computer relief painting in addition, adjust the position of speculum or the direction of fibre-optic bundle, can replace human eye to look side ways, remove many people from and miss the main points, and can't appreciate the hardship of relief painting.

Claims

1, adopt two cannel broadcast three-dimensional televisions, these two channels broadcast stereo image synchronously.

2, imaging stereo processing unit, comprise speculum 1,2,3,4, wherein 2,4 at a distance of nearer, and accompany certain angle, and its reflecting surface is opposing, mirror 1 is reflected into 2 with picture A, go into left eye by 2, mirror 3 is reflected into 4 with picture A, goes into right eye by 4, by two secondary reflections of light, with the virtual image coincidence of picture.

3, imaging stereo processing unit comprises that two-beam leads fiber a and b, is characterized in transmitting by optical fiber the function of light, makes picture A inject left eye by a, and picture A injects right eye by b, and the virtual image of picture A and B is overlapped.

4, on 2 basis, increase the knob of adjusting the speculum anglec of rotation, in order to adjust virtual image position.
