Use high density multi-view image display system and the method for active sub-pixel rendering
The application is the entitled of filing date on November 04th, 2010 of submitting to China Intellectual Property Office " use the high density multi-view image display system of active sub-pixel rendering and method " the 201010543468.7 the divisional application of number application.
One or more embodiments relate to a kind of high density using actively (active) sub-pixel rendering and regard more Dot image display system and method.
In order to be effectively realized three-dimensional (3D) image, the image with viewpoint different from each other generally may Need to be watched by the left-eye/right-eye of user respectively.In order to realize this 3D in the case of not using wave filter Image (such as, it is not necessary to user brings filter lens to watch 3D rendering), described 3D rendering may need Being divided spatially based on viewpoint, this is referred to as automatic stereo and shows.Viewpoint can represent the light of generation View direction, from described view direction it can be seen that the particular figure of 3D rendering, thus ought generally watch During described image, the image provided along different points of view can be different from each other.Here, such as, because projecting The light of each eyes is from the different images along different points of view projection/viewing, so left eye can watch with right The image that eye is different.For the overall viewing of two width different images of same object thus produce 3D effect.
Therefore, in automatic stereo shows, optical facilities can be used to divide 3D rendering spatially, and show Show described 3D rendering.Here, as optical facilities, optical lens or grating (optical can be used respectively barrier).As optical lens, biconvex lens (lenticular lens) can be used, by described lenticular Mirror, can only/show/watch each pixel image from specific direction.Additionally, due to arrange in front of the display The physical slit (slit) on surface, uses grating to be only capable of watching specific pixel from specific direction.Using Lens or grating carry out in the case of automatic stereo shows, can showing a single left side basically at different directions Visual point image and right visual point image (that is, two visual point images), thus cause optimal place (sweet spot) Generation, in described optimal place, two width images are such as in the space overlying of respective left eye and right eye Lid.Described optimal place can have narrow width, and sighting distance and visual angle can be used to show.Here, depending on Away from being determined by the slit of the pitch (pitch) of lens or grating, visual angle can be based on expressible viewpoint Quantity.In this example, increase the quantity of display viewpoint to add the scheme of wide viewing angle and be referred to alternatively as automatic standing Body multiple views shows.

Will be explained in detail now the one or more embodiments shown in accompanying drawing, wherein, identical label All the time identical element is referred to.In this, embodiments of the invention can be in many different forms by reality Execute, and should not be construed as limited to embodiment set forth herein.Therefore, the most below by referring to accompanying drawing Embodiment is described, to explain each aspect of the present invention.
Embodiment may relate to the left-eye/right-eye position that can follow the tracks of user to the image that determines user and watch The image display system of view information and method, in one or more embodiments, based on a determination that viewpoint Information uses active sub-pixel rendering to provide the colourity or have without limited three-dimensional (3D) effect Brightness interference or the 3D rendering of distortion.Pixel rendering is only performed by performing sub-pixel rendering, aobvious The quantity of the viewpoint shown can quantity based on sub-pix and increase (such as, in one or more embodiments, Displayable/the quantity of viewpoint that may be viewed by is equal to the quantity of the sub-pix in 3D pixel), and optimum Image can use view information to be rendered with 3D rendering that is shown, that thus occur in sub-pixel rendering The reduction of quality will not occur.
It is only used as example, in order to show 3D rendering in the case of there is no above-mentioned filter lens, as viewing 3D During image, based on viewing location, there is the image of different points of view and can be shown and can be separately visible. Such as, the left eye of user and right eye can be shown single image respectively, thus 3D effect is provided.For Realize this effect, can be the most only can from specific direction from the light of each pixel emission of display Observing, this is shown to all directions with each Pixel Information and observes each pixel letter from all directions Comparatively speaking the 2D display of breath is significantly different.Such as, in order to from the light of each pixel emission only make It is observable from specific direction, generally can use lens or grating.
Fig. 1 illustrate according to one or more embodiments based on lens (such as, aforesaid biconvex lens) Orientation visual point image display.
As it is shown in figure 1, biconvex lens 120 can be disposed in the upper strata/outer layer of display 110.At this In the embodiment of sample, display can have multiple pixel, and each pixel has sub-pix (such as, display Hatched redness (R) sub-pix of the display illustrated in device 110, green (G) sub-pix of point-like With unmarked blueness (B) sub-pix).When the focus of biconvex lens 120 is placed in specific pixel or Asia Time in pixel, along lens axle 121 display pixel or sub-pixel values can from described specific pixel/Asia picture The element certain view corresponding with the position of beholder is extended by biconvex lens when being watched.Specific biconvex Lens 120 the most coaxially direct the light to different directions (if i.e., biconvex lens has 12 axles, then 12 different view directions are available).Therefore, when the direction (viewing of viewing biconvex lens 120 Direction) when being changed, lens axle 121 may move, thus represent from such as can extended not Different pixels or the different points of view of sub-pix with image.Such as, it is shown as void when the direction of user's viewing During line 130, the sub-pix of dotted line 130 process can be extended by biconvex lens.In such a way, with The view direction user changes, and can show other Pixel Information, thus can show based on the user side of viewing To and other visual point images of changing.For further instruction purpose, the Part I 510 of Fig. 5 is drilled How shown can be by the different view direction of the most coaxially generation of biconvex lens, as by the instruction degree changed Shown in number (such as, from the central shaft of biconvex lens from-10 ° to+10 °).Such as, regarding of illustrating 1. around, the respective shaft of biconvex lens produces the change of positive 10 ° along view direction to point.
In order to visual point image is shown as pixel, pixel unit or sub-pix unit can be used.As mentioned , sub-pix unit can be to have the minimum pixel image unit of display of wall scroll colouring information (such as, The list of each in redness (R) in instruction RGB color, green (G) and blue (B) Position), and described pixel unit can be the pixel (example for obtaining by being combined by sub-pix As, R sub-pix, G sub-pix and B sub-pix are totally thought common for single pixel) performance (example As, there is the information of all colours component) the minimum image unit of display of colouring information completely.Figure The method of 1 is defined as pixel rendering.
Fig. 2 illustrates each for pixel rendering and sub-pixel rendering according to one or more embodiments Dot structure.Every solid line in the part 210 of Fig. 2 and part 220 may indicate that all of biconvex lens Each lens axis of lens axis.Part 210 illustrates all multiple sub-pixs of single lens axle process Represent the situation of single visual point image.Such as, for part 210, below the first axle of biconvex lens Selected multiple sub-pixs be the most optionally directed along the first viewpoint direction, another at biconvex lens Selected multiple sub-pixs below one axle are the most optionally directed along the second viewpoint direction, in biconvex Selected multiple sub-pixs below the another optical axis of lens are the most optionally determined along the 3rd viewpoint direction To, the multiple sub-pixs selected by below the axle finally illustrated of biconvex lens are the most optionally along Four viewpoint direction are directed.Additionally, this will be referred to as pixel rendering.As shown in part 210, specific double Each axle of convex lens all passes/passes through and (such as, produces each different correspondence based on each lens axle Visual point image) there is all three R of colouring information completely of all colours component, G and B Sub-pix.
Part 220 illustrates such a case: the single lens axle of biconvex lens through/through single sub-picture Element, each sub-pix for 3D pixel causes different points of view image, and this is referred to alternatively as sub-pixel rendering. It is only used as example, each lens axle process in multiple lens axles of biconvex lens/through respective selection Sub-pix, in order to each different viewpoint based on each lens axle represents fixed by the sub-pix of described selection The single color component of justice.(that is, can be based on user as in figure 2 it is shown, 12 different viewpoints can be there are That watches biconvex lens watches selected sub-pix directionally independently).
As mentioned, in pixel rendering, colouring information is (such as, from along identical lens axle completely All R, G and B colouring informations of each sub-pix) jointly can be showed about single lens axle, Thus show visual point image with three color components without cross-color.
Differently, in the case of sub-pixel rendering, only can expect earth's surface about arbitrary single lens axle Existing single color component, this can cause cross-color.But, as mentioned, when using such Asia During pixel rendering, Comparatively speaking can show increased number of visual point image with pixel rendering, this increases in performance The multiple views display aspect of the visual point image adding quantity can be an advantage.Therefore, pixel rendering and sub-picture Element renders both and has respective merits and demerits.
Fig. 3 illustrate according to one or more embodiments by pixel rendering and each product of sub-pixel rendering Raw viewpoint.That is, in the case of multiple views shows, when user watches multiple views between visual point image During display, the eyes of user can watch two visual point images the most respectively.In this example, at pixel wash with watercolours In the case of dye, along with the minimizing of the quantity of the visual point image showed, the interval between viewpoint or spacing meeting Increase, and cause the difference between visual point image bigger, therefore can produce the colourity between viewpoint significantly bright Degree interference.
With reference to Fig. 3, solid line may indicate that produced by pixel rendering viewpoint (such as, the viewpoint of display 2.- 5. the available viewpoint using pixel rendering can be represented).But, for sub-pixel rendering, along with the number of viewpoint Amount (such as, for viewpoint 2.-5. between the availability of viewpoint) become big, expressible visual point image Quantity the most correspondingly increases, thus interval or the spacing between viewpoint can reduce, any color therefore produced Degree brightness interference can be unimportant.With reference to Fig. 3, dotted line may indicate that the viewpoint produced by sub-pixel rendering. In this example, produce similarly also by sub-pixel rendering in Fig. 3 by regarding that pixel rendering produces Point, described sub-pixel rendering provides extra viewpoint.
That is, in the case of pixel rendering, high-quality visual point image (example can be showed from viewpoint accurately As, each visual point image has all three color component), but, the parallax between viewpoint can be relatively large, Result in obvious cross-talk.In sub-pixel rendering, along with the increase of the quantity of viewpoint, Any observable cross-talk between viewpoint can be the most unimportant, but, in each viewpoint Image there will be colored shadow (ghost).In this manner, see from the position different from desired viewpoint The quality of the image seen can have adverse influence to the 3D effect of 3D display and cause eyestrain.Such as, Even if left eye is appropriately placed the viewpoint of correspondence, but when right eye is outside viewpoint, also can be only at one There is cross-talk at eyes significantly, thus eyestrain can increase.
Use left eye and the sub-pixel rendering of right eye of user.
According to one or more embodiments, in order to realize while producing increased number of visual point image, Between viewpoint, there is not the 3D rendering of cross-talk or colored shadow, or subtract between viewpoint There is cross-talk or the 3D rendering of colored shadow less, can follow the tracks of the left eye of user and right eye come to User shows most suitable visual point image.In this case, can watch in the limited fixed position of user Image in use pixel rendering, but, can use in the visual point image of change in location based on user Sub-pixel rendering.
Fig. 4 illustrates that the use usertracking scheme according to one or more embodiments determines viewpoint.At Fig. 4 In, the visual point image that the image currently viewing with user is corresponding can be determined by shooting user, such as, Shooting is performed by the camera 420 using the display 410 with display multi-view image to integrate. Being only used as example, display 410 is it is possible to show 12 different visual point images.
Fig. 5 illustrates the active sub-pixel rendering based on viewing viewpoint according to one or more embodiments.As Shown in Fig. 5, for the single 3D pixel on display, each visual point image is in 12 directions selected Or one of viewpoint may be viewed by.As it has been described above, Fig. 5 illustrate each viewpoint be how with in not Tongfang Corresponding to the light of performance, such as, described different directions according to the lens axle of corresponding biconvex lens at ± 10 ° Between change.In this example, when user is positioned at specific optimal place (that is, optimal viewing location), Can be from identical place viewing from the respective visual point image of all 3D pixels.In this case, Can be (such as, described by the respective visual point image in each direction in 12 directions of sub-pixel rendering acquisition Each visual point image is made up of single color).In this case, figure 5 illustrates the wash with watercolours of rendered pixel Dye operation.That is, as shown in Part I 510, about the left eye of user and right eye position (such as, By using camera shooting user to determine), it may be determined that right eye mainly positions along viewpoint 5, and left eye is main along regarding Point 9 location (that is, for this specific 3D pixel and corresponding biconvex lens, it is desirable to transmitting/viewing side To being the basis viewpoint 5 for right eye and the viewpoint 9 for left eye).
In this example, in order to remove the above-mentioned example colored shadow produced due to sub-pixel rendering, neighbouring The visual point image (such as, for visual point image 4 and the visual point image 6 of right eye) of viewpoint 5 can be changed For additional viewpoint image 5.That is, when assuming for different visual point images, each sub-pix has R, G With the respective information of one of B color, and original visual point image 5 can be such visual point image, When making described visual point image only have R colouring information described visual point image execution sub-pixel rendering, depending on Dot image 4 and visual point image 6 can be respectively converted into additional viewpoint image 5, to have for viewpoint figure As G colouring information and the B colouring information of 5, not for their visual point image 4 and visual point image 6 The colouring information of each of which.Therefore, according to embodiment, such as, additional viewpoint image 5 still edge The different directions direct light of each of which of viewpoint 4 and viewpoint 6, but additional viewpoint image 5 will provide with The colouring information of the image of viewpoint 5 correspondence, rather than be provided for viewpoint 4 or the image of viewpoint 6 Respective colouring information.Therefore, similarly, can for left eye, visual point image 8 and visual point image 10 It is rendered as the additional viewpoint image 9 with the colouring information different from original visual point image 9 respectively.As Shown in the part 520 of Fig. 5, use this active sub-pixel rendering, neighbouring visual point image be converted into The visual point image that the eyes of user are corresponding, thus, from the point of view of the viewpoint of user, perform sub-pixel rendering Image can actual look like by pixel rendering scheme more accurately coloured.In this manual, Including (such as, based on a determination that user's view direction), the visual point image information of neighbouring viewpoint is converted to Such sub-pixel rendering scheme of identical visual point image will be referred to as active sub-pixel rendering.
In this example, when the user is mobile, right eye is movable to the position corresponding with viewpoint 4, left eye It is movable to the position corresponding with viewpoint 8.As example, here, viewpoint 4 can show original viewpoint figure As the G colouring information of 4, the sub-pix corresponding with neighbouring viewpoint 3 and viewpoint 5 can be converted to The B colouring information of viewpoint 4 and R colouring information, or it is controlled to show respectively the B color of viewpoint 4 Information and R colouring information, rather than viewpoint 3 and the colouring information of viewpoint 5.The conversion of colouring information also may be used It is applicable to viewpoint 8 by above-mentioned identical method.By such method, left eye and right eye about user close It is positioned the image of certain view, such as, change based on customer location, about each 3D picture suitablely The quantity of the producible viewpoint of element is 12, and sub-pixel rendering can be used to obtain.
Fig. 6 illustrate according to one or more embodiments based on a determination that the active of movement of viewing viewpoint sub- Pixel rendering.Fig. 6 be illustrated based on when the left eye of user move to respectively with viewpoint 4, viewpoint 3 and viewpoint 2 During corresponding position, and when the right eye of user move to right with viewpoint 9, viewpoint 8 and viewpoint 7 respectively During the position answered, the change of the image value of performance on lens.Here, Fig. 6 illustrates for viewpoint 4, regards The active sub-pixel rendering of point 3 and viewpoint 2 and viewpoint 9, viewpoint 8 and viewpoint 7 is left with based on each Eye viewpoint 4, elaboration (that is, each viewpoint of respective shaft of corresponding biconvex lens of viewpoint 3 and viewpoint 2 Respectively with corresponding lens axle shown in phantom representing biconvex lens).
In order to use above-mentioned active sub-pixel rendering scheme to show 3D rendering, it may be necessary to suitably picture Element structure and lens arrangement, and it needs to be determined that the left eye of user and the position of right eye, and may need Perform corresponding sub-pixel rendering.See figures.1.and.2, be only used as example, describe use lens The method of display multiple views 3D rendering, but, in one or more embodiments, for high-quality Active sub-pixel rendering, dot structure and lens arrangement may need to meet following condition (1) to (3):
(1) through/through phase may be needed about the distance the lens axle of the 3D pixel of each viewpoint With.I.e., it may be necessary to form the viewpoint figure that each sub-pix in 3D pixel produces at a predefined interval The direction of picture, thus form high-quality multi-view image.In order to form high-quality multi-view image, Biconvex lens and corresponding lens axle may need with based on vertically N number of in single 3D pixel The size of pixel and the ratio of the size of M sub-pix in the horizontal direction and the angle inclination that obtains.? In this example, N and M is integer, and described pixel and sub-pix may indicate that the pixel of display floater and sub-picture Element.Selectively, such as, show that the display unit of multiple visual point image may show the 3D formed by needs Pixel, thus optical axis is sub-with M in the horizontal direction with size based on N number of pixel vertically The ratio of the size of pixel and the angle that obtains tilts.
Fig. 7 illustrates the dot structure for active sub-pixel rendering according to one or more embodiments and bar Part.With reference to the Part I 710 of Fig. 7, as the example of description condition above (1), 3D pixel The vertical size of 711 can be indicated by " y ", and can have the vertical pixel distance of display floater value two Value again.Additionally, the horizontal size of 3D pixel 711 can be indicated by " x ", and when 3D pixel 711 Horizontal size time there is the equidistant value with the horizontal pixel of display floater, unified viewpoint can be produced Image.Additionally, as the example of the dot structure meeting condition above (1), such as, biconvex lens Lens axle may need have the angle of inclination " θ " relative to vertical direction, described " θ " can be by following Equation 1 determine.
θ=tan-1(x/y)=tan-1(M/N)
