Description
Technical field
In the electrical equipment imaging device 2D imaging device converted to a kind of liquid crystal light valve that flashlight is converted to two-way rotatory polarization three-dimensional imaging of 3D use in image-forming apparatus.
Background technology
TV and 2D imaging device are that widely used ripe imaging technique equipment is gone up by society at present.People's vision is viewed and admired though existing TV and 2D imaging device can tentatively satisfy, information transmission and obtain the demand of relevant vision imaging signal,, still can not satisfy people more true to nature to visual signal, more specialty, have more artistic further pursuit.
In recent years, the invention of 3D image technology, application reach progressively and popularize, and have tentatively remedied the above-mentioned deficiency of 2D image documentation equipment, have satisfied the pursuit that people view and admire more true to nature, more professional, have more aesthetic feeling 3D image.
But, existing 3D projection imaging equipment, technology is formed more complicated, has that cost is high, a technological problem such as high-leveled and difficult of Operation and Maintenance.Simultaneously, still can't all eliminate in a large amount of 2D imaging device short time that exist in the existing society, can not realize the 3D imaging again, can not satisfy the demand that people fully use social storage 2D imaging device 3Dization.
Summary of the invention
The objective of the invention is to convert flashlight the technology of two-way rotatory polarization three-dimensional imaging to, make one, can simplify the complex state of existing 3D projector equipment technically through a kind of; Two; Can be easily with social storage 2D imaging device; Through adding attachment device and, making it become the 3D imaging device to the simple process of interlock circuit, not only can make existing 3D projector equipment technical simpler, cost is cheaper; And, can effectively solve social storage 2D equipment 3D imagingization application problem.
The present invention is made up of polaroid, liquid crystal cell and phasic difference compensate film, and liquid crystal cell is between polaroid and the phasic difference compensate film, and polaroid is at natural light incident side, and the phasic difference compensate film is at the imaging end.
Polaroid is by 2-10 layer TAC film and 1 layer of composite membrane that the PVA film is formed, and the composite membrane gross thickness is 0.10mm-3.0mm; Thickness of liquid crystal box is 0.2mm-2.5mm; Phasic difference compensate film thickness is 0.03mm-0.2mm.
Have with the technical unit of the supporting imaging of the present invention: video signal change-over circuit, signal acquiring system, synchronization control circuit, driving circuit.
The connected mode of the present invention and supporting imaging technique unit is divided into two kinds; When independent 3D forms images; Its connected mode is: playback equipment is connected with signal acquiring system with display device simultaneously; Signal acquiring system is connected with synchronization control circuit, and synchronization control circuit is connected with driving circuit, and driving circuit is connected with liquid crystal light valve.
When the 2D imaging device converts the 3D imaging device to; Its connected mode is: playback equipment is connected with the video signal change-over circuit; The video signal change-over circuit is connected with signal acquiring system with display device simultaneously; Signal acquiring system is connected with synchronization control circuit, and synchronization control circuit is connected with driving circuit, and driving circuit is connected with liquid crystal light valve.
Course of work when independence 3D of the present invention forms images is following: signal acquiring system collects imaging signal from the conventional pictures signal source, sends driving circuit to through synchronization control circuit, and driving circuit drives the present invention realizes two-way rotatory polarization three-dimensional imaging.
When the present invention changes the 3D imaging device with the 2D imaging device; Its course of work is following: at first video conversion circuit is connected with 2D imaging device imaging output terminal; Send driving circuit to through synchronization control circuit, driving circuit drives the present invention realizes two-way rotatory polarization three-dimensional imaging.
As far as 3D projection imaging equipment, the present invention is connected with known technology peripherals and realizes 3D when imaging, and only need unit work to get final product, quite existing 3D projection imaging equipment can reduce a set of equipment, technically with cost on all greatly brief; The present invention with known technology peripherals connection basis on, simply add the video signal change-over circuit after, can realize 2D imaging device 3D imagingization, successfully solve the problem of existing 2D equipment 3D imagingization, number of applications demand and huge market potential are arranged.
