The three-dimensional sheet of seeing is seen screen device
Technical field
The utility model relates to a kind of viewing apparatus, relates in particular to a kind of sight sheet sight screen device that is used to watch stereotome or three-dimensional video-frequency.
Background technology
Before more than 100 years, people just with the twin-lens camera take parallax about two photos, watch solid (3D) picture with special viewing equipment, this mode spreads so far always.Its principle of work is, utilizes twin-lens camera anthropomorphic dummy's two position, and scenery is taken the photo that two width of cloth have parallax respectively.Then by viewing equipment, make people's left eye only can see the photo of left lens shooting, right eye only can be seen the photo of right lens shooting, by the synthetic piece image of brain, produces stereoscopic visual effect.
People are when watching object, and the inside angle of the focusing of eyes and sight line can be regulated naturally with object is far and near.Usually angle is a viewing ratio near 0 ° of about 12 ° of arriving nearby from afar.When people's eyes focus on a certain apart from the time, it is limited that its eyes are regulated the scope of watching angle naturally.If when the angle that scene needs eyes to regulate surpasses this scope, regulate, eyes are felt fatigue and discomfort with regard to needing the bigger power of human.
Since the parallax effect of two-shot, this subject be presented at relative viewing distance fixing about spacing relation on two photos be: the distant objects spacing greatly, object spacing nearby little (shown in Figure 1A and Figure 1B).From Figure 1A and Figure 1B as can be seen, object C from the distance of bicamera 10 farthest, object A is nearest from bicamera.Be reflected on two photos, the distance that left side photo 10A and right photo 10B go up between the objects displayed C is maximum, the distance that left side photo 10A and right photo 10B go up between the objects displayed A is minimum, and the distance that left photo 10A and right photo 10B go up between the objects displayed B falls between.
If viewing equipment is designed to be suitable for watching distant view thing (for example object C) (or large-size photo), to watch with such viewing equipment so having the close shot thing when (for example object A), two width of cloth pictures will close up excessive, can't see correct stereoscopic views.At this moment often need people's eyes to use eyes bracketing methods (being commonly called as " corn " method) to regulate the inside angle of sight line, the close shot thing can correctly be closed up, see stereoeffect.Briefly, be suitable for watching the viewing equipment of distant view thing, be unsuitable for watching the close shot thing.Otherwise,, just be unsuitable for watching the distant view thing if viewing equipment is designed to be suitable for watching close shot thing (for example object A) (or reduced size photo).Therefore, traditional stereo viewer can't be taken into account reasons such as various distances owing to photographed, lens data difference, photo or screen size difference simultaneously, is presented at left and right sides picture scenery spacing and differs bigger problem and form.
Again on the one hand, because the interpupillary distance of people's eyes varies with each individual, differ a lot of sometimes, a kind of viewing equipment of specification more can't satisfy different human needs.Use unaccommodated viewing equipment to watch stereo-picture often to be easy to generate eye fatigue, dizziness even unhealthful phenomenon such as feel sick.This also is the three-dimensional major reason that sheet can not be popularized of seeing.

Embodiment
Describing three-dimensional the sight before sheet sees screen device of the present utility model, describing the principle of work that three-dimensional imaging and eyes overlap earlier, to help to understand the utility model.
As everyone knows, when light enters into the different alternative printing opacity object of density (for example glass, organic glass, optical resin etc.) from air, can produce refraction effect.Fig. 2 shows the index path of the refraction effect that light produces when air enters into organic glass.
Utilize this principle, when human eye is seen object 1 by prism (seeing also Fig. 3), through ray refraction, the position of the object 1 that the people feels moves to object 2, and the object of just seeing can be to the thin direction displacement of prism.The magnifier that we use always (convex lens) can be regarded unlimited a plurality of continually varying prism as and be spliced.The prism angle of magnifier central point correspondence is 0 degree.That is to say that the object of outwards seeing by the central point of magnifier can not produce displacement.Stretch out from central point, its corresponding prism angle is increasing, and just light is also big more through position decentering point its refraction angle far away more (prism angle) of magnifier, and the ohject displacement of seeing is also big more.
Fig. 4 schematically shows the situation of the displacement of the object of seeing by magnifier.41 is magnifier among Fig. 4.When human eye was watched object 1 by magnifier, if magnifier 41 is moved to the left, according to above-mentioned principle, because its corresponding prism angle diminishes, the object of seeing 2 was more little from the displacement of object 1; Otherwise if magnifier 41 is moved right, because its corresponding prism angle becomes big, the object of seeing 2 is big more from the displacement of object 1.That is to say,, can change the displacement of object by the position of moving magnifier according to this principle.If regulate the magnifier of right and left eyes simultaneously, then can change the spacing of two objects that arrive soon.The utility model designs with regard to being based on this principle.
