Description
Technical field
The present invention relates to the bore hole stereo display technique, relate in particular to a kind of tracking mode bore hole stereo display method of adjustment, adjusting device and relevant device, system.
Background technology
Present stereopsis display mode is broadly divided into 3 types, and promptly spectacle, head-mounted display (Head Mount Display) formula and this paper are with the bore hole formula of introducing.The bore hole formula comprises numerous species, adopts realizations such as lens arra formula technology, parallax obstacle type technology usually.Mainly (Two-Dimensional, 2D) flat-panel screens (comprising LCD, plasma display, Field Emission Display and display of organic electroluminescence etc.) cooperates light-splitting device such as grating to assemble to the bore hole 3 d display device by two dimension.The grating that uses can be divided into slit grating and cylindrical grating, and accordingly, raster pattern 3D three-dimensional display also has two kinds of implementations: slit grating formula 3 d display device and microlens array 3 d display device.In diversified bore hole formula stereo display technique, what begin at first to develop is eyes (or claiming 2 viewpoints) modes.After the eyes mode, many more ultra many viewpoints modes of (or claiming many viewpoints) mode, panorama (ray space reproduction) mode and viewpoint number are developed out in succession.
Bore hole stereo display exist one very major defect is the restriction that receives viewing areas, utilizes head tracing system can effectively alleviate this defective, and it is a lot of to make viewing areas increase.Head tracing system can detect beholder's position in real time; If the stereo display effect can not be seen in the beholder position; The display parameters that can adjust display change the position in the zone that can watch stereo display effect (not comprising contrary looking), make the beholder see the stereo display effect.
Industry has been developed the technology that can when the beholder moves, switch left and right (LR) eye pattern picture for a long time, and is as shown in Figure 1, is placed with parallax barrier before the liquid crystal panel, can left-eye image and eye image be separated.The beholder is when initial position, and left eye sees that left-eye image, right eye see eye image, can see the stereo display effect.When the beholder has been moved to the left when being equivalent to its interocular distance such as 65mm, the left-and right-eye images that this moment, the beholder saw at first exchanges, and parallax is put upside down, and this state is called " against looking ", and the beholder can not see the stereo display effect.And if utilize tracking technique, the demonstration of left-eye image and eye image on the switchable liquid crystal panel when the beholder moves changes the viewing areas of left-eye image and eye image, like the right figure of Fig. 1.This moment, the beholder left eye was seen left-eye image, and right eye is seen eye image, also saw the stereo display effect after the beholder is moved.Afterwards, industry has been developed the conversion grid technique that can laterally move grid positions again.As shown in Figure 2, when lateral shift took place for beholder's position, if only moved the half the of interocular distance, for example during 32.5mm, beholder's images of left and right eyes can be seen eye image and left-eye image simultaneously, crosstalk phenomenon promptly occurs.In this case, only need to move slightly grid, just can eliminate and crosstalk.
In the tracking mode bore hole three-dimensional display system of supporting many viewpoints, also can adopt aforesaid way adjustment.Normally; In the bore hole stereoscopic display device of N viewpoint, N visual point image (abbreviating view as) can be provided, N＞2; Display floater transversely to be arranged in the 1st view (view1), the 2nd view (view2) ..., the demonstration that circulates of the view sequence of N view (viewN); In the literary composition, this view sequence view1view2......viewN is called N viewpoint view sequence, each view wherein is used to show the parts of images of respective viewpoints.In the N viewpoint view sequence any two adjacent view be view1 and view2, view2 and view3 ..., view (N-1) and viewN satisfy: last view gets into beholder's left eye (promptly as left-eye image) can produce the stereo display effect when back one view enters into beholder's right eye (promptly as eye image) simultaneously, and promptly two adjacent view have normal parallax.The 1st view in the N viewpoint view sequence can be described as first view, and last 1 view can be described as the tail view.It is right that above-mentioned two adjacent view constitute an image, and right like view1 and view2 image, the last view of this image pair is view1, and back one view is view2.The unit of display that is used for showing a view of a N viewpoint view sequence on the display floater is called a display unit, and display unit is a logical concept, can be the pixel that is used to show a certain view, inferior pixel, inferior pixel or its combination.Be used to show that N continuous display unit of a N viewpoint view sequence is called a display unit arrangement cycle.Can the original position that display unit is arranged the 1st display unit (promptly being used for showing the display unit of the 1st view of N viewpoint view sequence) in cycle be called the original position that this display unit is arranged the cycle.
Bore hole 3 d display device with the band raster of supporting 4 viewpoints is an example; Shown in Figure 3 is from obtaining perpendicular to display floater and the direction intercepting that is parallel to the display floater width, has drawn display floater 10 and a part of light-splitting device 20 in the stereoscopic display device.The origin of coordinates of reference axis shown in Figure 1 can be defined in display center.The X-direction of this reference axis is also referred to as laterally, and Y axle (not shown) direction is also referred to as short transverse, and the Z axle is also referred to as fore-and-aft direction, and the Z coordinate figure is also referred to as viewing distance.
As shown in the figure, be arranged with the display unit 101 that is used for showing respectively 4 views on display floater such as the liquid crystal panel, by 1,2,3; 4,1,2,3,4; ... mode circulate and be staggered, wherein be denoted as 1,2,3,4 display unit and be respectively applied for and show view1, view2, view3 and view4.Among Fig. 3; Be denoted as 1; 4 continuous display units of 2,3,4 constitute a display unit and arrange the cycle; This display unit arrangement cycle is used to show one 4 viewpoint view sequence view1view2view3view4, and the original position that is denoted as 1 display unit is arranged the original position in cycle as this display unit.
Please with reference to Fig. 3; Branch light action through the spectrophotometric unit on the light-splitting device 20 201 (spectrophotometric unit of Fig. 1 is the grid cell in the slit grating, also can be the lens unit etc. in the lens arra) can spatially form the subarea of watching of staggered each view of circulation.Be labeled as 1,2,3,4 the subarea 30 of watching among the figure and show view1 respectively, view2, view3, the position of seeing on the distance is being fitted in the subarea of watching of view4.Fig. 4 a shows continuous 4 shapes of watching the subarea that mediate among Fig. 3, and inner the sign has 1,2,3; 4 quadrangle is represented view1, view2, view3 respectively; View4 watches the subarea, can see view1, view2 respectively; View3, view4, line segment BD sees distance to the distance of display for fitting.Omitted the subarea of watching of other positions among Fig. 4 a.Need to prove that the shape of watching the subarea of above-mentioned each view only is exemplary, maybe be also inequality for different display devices.
As previously mentioned, the subarea while right eye of watching that makes beholder's left eye be in view1 like the residing zone of beholder is in the subarea of watching of view2, and the beholder can watch the stereo display effect, and this zone is called view1 and the positive vision area of view2 image to forming; In like manner; The zone of watching the subarea of watching subarea while right eye to be in view3 that makes beholder's left eye be in view2 is called view2 and the positive vision area of view3 image to forming, and the zone of watching the subarea of watching subarea while right eye to be in view4 that makes beholder's left eye be in view3 is called view3 and the positive vision area of view4 image to forming.And if the subarea while right eye of watching that the residing zone of beholder makes beholder's left eye be in view4 is in the subarea of watching of view1, parallax is put upside down, and will produce contrary looking, and this zone is called view4 and the contrary vision area of view1 image to forming.Clear easily; In the N viewpoint bore hole three-dimensional display system, N-1 image be to view1-view2, view2-view3; ...; View (N-1)-viewN can form positive vision area separately respectively, and 1 image can form contrary vision area to viewN-view1, and each image can have a plurality of to the positive vision area (or contrary vision area) that forms.If the residing zone of beholder makes beholder's images of left and right eyes see a plurality of views, promptly produce and crosstalk, this zone is called crosstalk zone.
The positive vision area that forms is reached the position of contrary vision area according to each image of watching the subarea can calculate adjacent view formation in the N viewpoint view sequence of determined each view of display parameters; Fig. 4 b shows shown in Fig. 4 a positive vision area and the contrary vision area of each image to forming under the situation; The inner sign has 1; 2 quadrangle is represented view1 and the view2 image positive vision area to forming, and inner the sign has 2,3 quadrangle to represent view2 and the positive vision area of view3 image to formation; Sign has 3,4 quadrangle to represent view3 and the positive vision area of view4 image to forming.And inner the sign has 4,1 quadrangle to represent view4 and the contrary vision area of view1 image to formation.In the literary composition, also image is referred to as the right viewing areas of this image to positive vision area or the contrary vision area that forms.
In the tracking mode bore hole three-dimensional display system of many viewpoints, when beholder's position takes place laterally to move, can arrange the cycle or spectrophotometric unit squints to adjust to display unit.
Be example with 4 view system shown in Figure 3 still, supposing has 2 beholders, lays respectively at view1 and view2 image when initial to reaching view3 and the view4 image positive vision area to forming.In Fig. 5 a, suppose that 1 beholder has moved to view4 and the contrary vision area of view1 image to forming from view1 and view2 image to the positive vision area that forms, another beholder's invariant position at this moment, need make two beholders all be in positive vision area through adjustment.A kind of adjustment mode is that the display unit arrangement cycle is squinted; Like Fig. 5 b; Display unit is arranged the width of cycle to a display unit of reverse skew of X axle; The view that display unit on the same position shows will change, and correspondingly, contrary vision area is adjusted to the position that ought lastly face the district.As shown in the figure, former view4 and view1 image become view3 and the positive vision area of view4 image to forming to the contrary vision area that forms, and former view3 and view4 image become view2 and the positive vision area of view3 image to forming to the positive vision area that forms.After the adjustment, 2 beholders all are in positive vision area, can see the stereo display effect.Another kind of adjustment mode is that spectrophotometric unit is squinted; Shown in Fig. 5 c; To 1/4 of the forward migration spectrophotometric unit width of X axle, squinted in the position of the right viewing areas of each image each spectrophotometric unit, make 2 beholders all see the stereo display effect.
Yet inventor of the present invention recognizes after deliberation, adopts above-mentioned method of adjustment; The position of the viewing areas that each image is right all can change, thereby before and after the adjustment, the image that same position is seen is to difference; Cause all beholders all can feel and screen flicker influence viewing effect.

Embodiment
For making the object of the invention, technical scheme and advantage clearer, hereinafter will combine accompanying drawing that embodiments of the invention are elaborated.Need to prove that under the situation of not conflicting, embodiment among the application and the characteristic among the embodiment be combination in any each other.
The inventor recognizes; In the tracking mode bore hole three-dimensional display system of many viewpoints; Existing display unit is arranged the method for adjustment of period migration and spectrophotometric unit skew, because the right viewing areas of all images all can change, screen flicker is more serious.In order to reduce the screen flicker that this adjustment brings, the present invention proposes following multiple embodiment.
The embodiment of the invention provides the view more than N in N viewpoint bore hole three-dimensional display system; Needing will be when vision area be adjusted into current positive vision area; Replace the partial view in the current N viewpoint view sequence; Keep remaining partial view, right viewing areas remains unchanged to make parts of images as far as possible, and the beholder who is in these viewing areas just can not feel screen flicker.Thereby a kind of display parameters of image that can be used to adjust have been increased, i.e. N viewpoint view sequence to viewing areas.
As shown in Figure 6, the tracking mode bore hole stereo display method of adjustment of present embodiment is applied in the N viewpoint bore hole three-dimensional display system, and N＞2 comprise:
Step 110 is confirmed the view that will replace in the current N viewpoint view sequence;
To contrary vision area be adjusted to when last and when facing the position in district, can adopt the mode of replacement, then in current N viewpoint view sequence, the k that last view comprised of first view to the image pair of the said positive vision area of formation at front view
1Individual at front view, perhaps, adopt the mode of replacement, the k that the back view of the image pair that forms said positive vision area is comprised to the tail view at rearview
2Individual at rearview, confirm as the view that will replace, wherein, k
1, k
2Be integer, 1≤k
1＜N, 1≤k
2＜N, natural k
1+ k
2=N.When system can provide the view that is used to replace under this dual mode, preferably, the number of views that relatively will replace under the dual mode, a kind of mode that the number of views that employing will be replaced is less just compares k
1, k
2Value adopts k
1, k
2In less institute's corresponded manner, can more effectively reduce the influence of screen flicker to the beholder.
Be example still, suppose under the initial condition that the N viewpoint view sequence of demonstration is view5view6view7view8, need to be adjusted into against vision area the positive vision area of view7 and the formation of view8 image with 4 view system.At this moment, if adopt the mode of replacement at front view, because first view is view5, the last view that forms the image pair of said positive vision area is view7, thereby view5view6view7 is the view that will replace, k
1Value is 3; If adopt the mode of replacement at rearview, be again the tail view of N viewpoint view sequence because view8 is a back view that forms the image pair of said positive vision area, thereby view8 is exactly the view that will replace, the view that is applied to replace mutually is view4, k
2Value is 1.If the view system that is used under the dual mode replace all can provide, preferred replacement is confirmed as the view that will replace in the mode of rearview with view8, to keep more view, reduces to adjust the influence to the beholder.
Because the view that is used to replace need take storage resources, and also can there be certain skew in the composograph of formation with respect to former composograph after the replacement, so the sum of the view that system provides is limited, this can produce restriction to the employing of substitute mode.For example, 12 views altogether can be provided, use sequence view1 for 4 view system, view2 ..., view12 representes that continuous arbitrarily 4 views all can be used as the 4 viewpoint view sequence that display floater shows in the sequence.When 4 current viewpoint view sequence are view1view2view3view4; Just can not adopt the mode of replacement at rearview; Because adopt replacement when the mode of rearview; Need increase new view before the current N viewpoint view sequence, and system does not provide and can be used as the view0 that last view and view1 are paired into left-and right-eye images.At this moment,, can adopt 3 modes of replacement, also can all views all be replaced at front view if will adjust to view3 and the positive vision area of view4 image against vision area to forming.
Step 120 is obtained the view that is used to replace and is carried out the view replacement, and after the replacement, the view that view that is used for replacing and current N viewpoint view sequence keep is formed a new N viewpoint view sequence;
To adjust to when last when facing the position in district against vision area,, then be used to the k that replaces if adopt the mode of replacement at front view
1Individual view should be with the N-k that keeps in formula and the current N viewpoint view sequence in the wings
1Individual view is formed a new N viewpoint view sequence, promptly in new N viewpoint view sequence, and the k that is used to replace
1The N-k that individual view position is keeping
1After the individual view; If adopt the mode of replacement, then be used to the k that replaces at rearview
2Individual view should be with the N-k that keeps in formula and the current N viewpoint view sequence forwardly
2Individual view is formed a new N viewpoint view sequence, promptly in new N viewpoint view sequence, and the k that is used to replace
2Individual view is positioned at the N-k of reservation
2Before the individual view.Because form new N viewpoint view sequence; The view that just requires to be used for replacing is by in the preceding or view sequence formed of formula and the view of reservation in the wings, the last view of any two adjacent view get into beholder's left eye simultaneously after a view can produce the stereo display effect when entering into beholder's right eye.
Be example with above-mentioned 4 view system still, as previously mentioned, the N viewpoint view sequence of current demonstration is view5view6view7view8, needs to be adjusted into against vision area the positive vision area of view7 and the formation of view8 image.At this moment; If adopt the mode of replacement at front view; Then view5view6view7 is the view that will replace, for the view8 with formula and reservation in the wings forms new N viewpoint view sequence, can confirm that the view that is used to replace is view9view10view11; The new N viewpoint view sequence that the replacement back is formed is view8view9view10view11; Notice, show that the display unit that is used to show view9view10view11 is identical with the position of the display unit that is used to show view5view6view7 because N viewpoint view sequence is circulation.If adopt the mode of replacement at rearview; Then view8 is the view that will replace; For the view5view6view7 with formula and reservation forwardly forms new N viewpoint view sequence; Can confirm that the view that is used to replace is view4, the new N viewpoint view sequence that the replacement back is formed is view4view5view6view7.
The above-mentioned view that is used to replace can be the view of storing in advance, adopts the mode that reads to obtain during adjustment.Perhaps, the above-mentioned view that is used to replace also can generate when adjustment in real time, just can expand view sequence according to the parallax of each pixel on left-eye image and eye image of record or calculating, obtains new view.Perhaps, also can adopt the mode of storage in advance by partial view, partial view adopts the mode that generates in real time.
Step 130 shows new N viewpoint view sequence.
Suppose that the N viewpoint view sequence that shows under the initial condition is view5view6view7view8, the total view sequence that shows on the display floater can be expressed as:
view5view6view7view8view5view6view7view8view5view6view7view8......
As replacing view5 with view9, this total view sequence becomes:
view9view6view7view8view9view6view7view8view9view6view7view8......
