Abstract
The present invention provides a method for producing and reappearing stereo colour television image. Said method uses the left and right twin-lens of stereo colour telecamera to shoot two groups of pictures to produce two ways of vidio signals, and then the vidio signals are passed through a vidio signal synthesizer to produce the quasi-stereo colour vidio signals of every frame alternation of left-right pictures, and then the above-mentioned quasi-stereo colour vidio signals are recorded by vidio recorder or transmitted to space by television station, and then those signals are received by TV set, and then the quasi-stereo colour pictures are displayed, and passed through the vidio signal controller and liquid crystal glasses, and then the pictures shot respectively by left and right lens can be respectively watched by left and right eyes from the liquid crystal glasses, so that stereo colour image can be formed.
Description
The present invention relates to a kind of ICT (information and communication technology), especially a kind of production of stereo colour TV picture and replay method specifically utilize ordinary color tv set to watch the method for stereo colour program.
At present, the common plane color television set generally is familiar with for people, but though three-dimensional colour television does not all also have product to come out in research, in known technology, discloses a kind of stereo-television system in No. 88100234.8 documents of Chinese patent application both at home and abroad.This system controls by synchronous electric sampler, export the signal of two video cameras in turn, launch by transmitter then, do the synchronous demodulator demodulation at receiving terminal utilization distortion row to type liquid crystal cell and polarizer, about allowing respectively two see by the polarizer glasses again about the images of two video camera productions.In this kind stereo-television system, use two video cameras and distortion row to liquid crystal synchronous demodulator and polarizer etc., it is many that weak point is to take equipment, and production expense height is not easy to adjust synchronously and generally apply.
The objective of the invention is to overcome above deficiency, provide a kind of simple and easy to do, it is few to take equipment, and the production expense is low, the production of the stereo colour TV picture that effect is true to nature and replay method.
The objective of the invention is to realize in the following manner; (1) stereo camera shooting (2) signal synthetic (3) record or emission (4) television reception (5) frequency division control (6) brilliant three-dimensional color image watches.
Figure of description is the production of three-dimensional color image of the present invention and the step schematic diagram of replay method.
Describe in detail below with reference to Figure of description the production of stereoscopic colour TV image of the present invention and replay method being done.
1, shooting: utilize the twin-lens stereo camera about two camera lenses scenery is taken, produce the two-path video signal;
2, signal is synthetic: it is synthetic that the two-path video signal of stereo camera output carries out the signal cutting through the vision signal synthesizer, makes the two-path video signal become the accurate stereo colour vision signal of the alternate single channel of every two field picture;
3, the emission of signal and record: the accurate stereo colour vision signal from the vision signal synthesizer is being transmitted into space with the transmitter antenna of accurate stereo colour vision signal in TV station by the video tape recorder record on the video tape or directly;
4, television reception: on the ordinary color tv set phosphor screen, obtain accurate three-dimensional color image by utilizing common color television set to receive accurate stereo colour vision signal, the captured alternate image of every frame of two camera lenses about promptly obtaining, specifically about the captured every frame one after the other of picture of two camera lenses on phosphor screen, occur;
5, frequency division control.Accurate stereo colour signal produces two pulse signals through the frequency division controller;
6, watching of three-dimensional color image, utilizing the electrical characteristics of liquid crystal to make liquid crystal glasses links to each other with the frequency division controller, the frequency division controller produces two liquid crystal lens one after the others of pulse signal control light is cut blocking-up, the frequency of its cutting blocking-up is identical with the frequency that every frame picture occurs on phosphor screen, be that the picture of left lens shooting is when occurring on phosphor screen, liquid crystal energising blocking-up light on the right eyeglass of liquid crystal eyes passes through, when the picture of right lens shooting occurs on phosphor screen, liquid crystal energising blocking-up light on the eyeglass of a liquid crystal eyes left side passes through, like this under the control of frequency division controller, two eyeglasses of liquid crystal glasses are alternately blocked light, make two eyes can only see the picture that corresponding camera lens is taken, add the sight equation of eyes, what people were seen in the liquid crystal eyes is exactly an a width of cloth complete three-dimensional color image.
The production of stereo colour TV picture of the present invention is compared with existing technology with replay method, has the three-dimensional television production easily, watch conveniently, it is few to take the equipment personnel, utilize production that existing general color television equipment just can realize the three-dimensional colour television program and watch, utilize the general color television receiver can see that three-dimensional program also can see ordinary tv programme for watching the user, very convenient, therefore method of the present invention has good value for applications.
Claims (7)
1, the production of stereo colour TV picture and replay method, comprise stereo camera shooting → signal synthesize → record and launch → television reception → frequency division control → three-dimensional color image watches.
2, method according to claim 1, it is characterized in that the twin-lens stereo camera about two camera lenses scenery is taken, produce the two-path video signal.
3, method according to claim 1 is characterized in that the vision signal of stereo camera production enters the vision signal synthesizer, makes the alternate accurate stereo video signals of left and right sides camera lens picture.
4, method according to claim 1 is characterized in that accurate stereo video signals that the vision signal synthesizer is made enters video tape recorder or directly by TV station's launching tower signal launched.
5, method according to claim 1 is characterized in that television receiver reappears accurate stereo video signals on phosphor screen.
6, method according to claim 1 is characterized in that the frequency division controller controls the generation two pulse signals respectively with the accurate stereo colour signal of TV station emission.
7, method according to claim 1 is characterized in that utilizing liquid crystal glasses that light is cut its frequency of blocking-up and pulse signal synchronised, makes every liquid crystal glasses sheet can see the coloured image of corresponding left and right sides camera lens production respectively.
