Description

Full frame picture-in-picture

Technical field the present invention watches and independent many pictures picture-in-picture techniques of controlling program separately and being independent of each other the spectators more than two or two simultaneously with full frame form on same screen.

This invention can be widely used in image processing equipments such as television set and set-top box thereof, TV box, TV card, projecting apparatus.We know background technology, present many pictures technology (we are called picture-in-picture techniques here) is the picture of several programs to be divided into some parts mode at screen from the space to realize, picture is divided into primary and secondary two parts to be shown, simply picture is divided into two or is equally divided into several pictures, influenced the whole appreciation effect of picture and the integrality of picture so greatly, spectators also can't control separately the program of watching separately simultaneously.

Summary of the invention the purpose of this invention is to provide a kind of technology, is allowing spectators be independent of each other by wear the program that special glasses can all be watched with full frame form simultaneously and independence is controlled separately on same screen on the basis of not cutting apart the total painting face.The present invention is further described below in conjunction with accompanying drawing for description of drawings, and this figure is the picture in picture TV set block diagram that the present invention is applied in two pictures on two high-frequency TV machines.Part among the figure in the dotted line is as good as with general color television set block diagram, omitted some many institute's weeks the details square frame, increased the receive path and the insertion treatment circuit of B picture signal.

In order to eliminate and avoid interference between signals, TV signal is transported to the tuning circuit of two pictures of A B respectively by distributor, and this circuit can be high frequency hair style picture tuning circuit and digital type image treatment circuit.For ease of realizing independent control to A B two channel pictures, we are two remote control systems for TV has been equipped with, this system each remote controller when using picture-in-picture function can be controlled a corresponding program separately, and two remote controllers can be general when cancellation picture-in-picture function normal play.TV signal by two tuning circuits after through in put detection two pictures audio signal be exaggerated the back and export by dedicated channel, loud speaker output is sent in the sound accompaniment of A picture, earphone output is sent in the sound accompaniment of B picture, the vision signal one tunnel of A picture is sent to video switching circuit, be sent to the image storage control circuit behind one tunnel process synchronizing separator circuit, the vision signal one tunnel of B picture directly is sent to the image storage control circuit, the image storage control circuit is sent in another road after synchronizing separator circuit is handled, here picture signal is gathered and encoding process according to the call format that is read out, just system will arrange properly and when export which width of cloth picture, with which kind of form output, (be that A B two width of cloth pictures are with A B A B ... rotation output still with A A B B A A B B ... order output, be interlacing output or output etc. line by line, several forms have the different-format requirement when being applied to the different video output equipment) simultaneity factor will arrange properly and when which light valve be opened, when close which light valve, video information after system will encode then is sent to video switching circuit, here switching circuit is connected after the picture-in-picture function picture signal and is sent to imaging system by image amplifier and is presented in screen, A meanwhile, the B light valve is also being accepted in good time the opening and closing of system control, is accurately controlling to mirror entering of our eyes image.

The object of the present invention is achieved like this for embodiment, we utilize persistence of vision principle to go up from the time picture is cut apart and handled, some programs that we will select are earlier handled the back by collection and coding module and are pursued the width of cloth with the interspersed screen that is output in of full frame form, the current picture of every suit program is exported a full frame picture in turn, system exports next group of pictures of having gathered and having finished sign indicating number in the same way then, and picture could get up in activity like this.For making picture seem natural and tripping, the stroboscopic frequency of every suit program picture is preferably in more than 50 hertz, what occurred this moment on our naked eyes screen is that a few programs pictures are superimposed upon image together, we filter out other unnecessary program pictures by the light valve image filtering glasses of wearing corresponding a certain program and being equipped with then, the image filtering glasses here are the light valves with Glasses structure and shape that adopts optical mirror slip and liquid crystal material to be made, link to each other with main frame by wired or wireless mode, (when the wireless connections form then itself self-powered and command reception control system and sound accompaniment receiving system) thus the image that receives the switching control single width complete picture of the control command control light valve that main frame sends passes through.Only corresponding independent one road program of each road image filtering glasses, only allow to pass through with own corresponding one road program picture, just after we have selected picture-in-picture function, system just begins to gather current picture on the channel that we configure, can gather the relatively little channel picture of a width of cloth channel number earlier, to be output in screen behind its coding, simultaneously output order allows light valve that should channel is opened or made the light valve of corresponding other channels close, gather the big relatively channel picture coding of back channel number then successively and output to screen, meanwhile output order allows the light valve of corresponding this channel of active screen open or makes the light valve of corresponding other channels close, also can be according to the first big after small acquisition order output of channel number, also can be according to the order of radio frequency behind the first video or first radio frequency rear video, screen that corresponding with it group light valve of which programs picture occurs and opens in a word, other light valves are closed, we can only see that by light valve image filtering glasses the corresponding program picture of a cover can't see together the picture of other programs that broadcast on screen like this, and what see by the image filtering glasses in different paths is TV programme different on same screen.Simultaneously on light valve image filtering glasses, also be equipped with voice output, can will export synchronously television field frame that should program.The image filtering glasses in each path can be equipped with the identical glasses of a plurality of functions, and this system also is equipped with independently remote control system in addition, the program that spectators can independently draw oneself up and watch under picture-in-picture state.We can enjoy perfect full frame television image and be independent of each other like this.

We have formulated respective coding according to the different video output equipment in the image storage control circuit, when being applied to the equipment of projection-type, picture signal can be according to the concrete condition coding back output continuously of aspects such as screen width ratio that configures and pixel, but when being applied to the picture reproducer of fluorescent imaging pipe and liquid crystal type, except factors such as concrete screen size and pixel require, also because fluorescence and liquid crystal material have the problem of several milliseconds of response speeds, so if the picture of the different programs of interspersed continuously output will cause the partial stack and the ghost of picture when watching TV by light valve image filtering glasses, therefore system can accurately be controlled at last width of cloth picture according to the concrete response time of picture reproducer and after screen disappears next width of cloth picture presented fully, just last pixel of A picture fully after screen disappears and then first pixel of B picture begin to light, simultaneously because also there is the problem of response speed in light valve itself, therefore system will accurately control corresponding light valve and accurately open, just close fully to the light valve that disappears fully to this picture, we can enjoy clear and smooth separately like this, three-dimensional lively picture.

According to above-mentioned principle, we can also increase the quantity of picture-in-picture program, only needing to increase corresponding signal receives and treatment channel, increase corresponding remote control system and sound accompaniment output system and corresponding light valve glasses simultaneously, but be subjected to the restriction of present imaging technique, the quantity of full frame picture-in-picture program is difficult for too much should guaranteeing that the stroboscopic frequency of every suit picture-in-picture program picture is not less than 50 hertz that picture just can seem natural and tripping like this.

Foregoing invention has been arranged, and we can make us live harmoniously more enjoying separately perfectly program with our friend and household on same screen under the situation that does not influence other people.
