Technical field
For known 3d numerical digit billboard (3d digital signage), usually using lens arra
(lenticular) the what comes into a driver's segregation apparatuss being constituted, to show a naked 3d dynamic image regarding, reach the mesh providing 3d advertisement
's.This known 3d digital advertisement board, is limited to the problem of volume production technology and cost, typically can only be using aobvious compared with small screen size
Show device and adopt fixed what comes into a driver's segregation apparatuss.So-called fixed what comes into a driver's segregation apparatuss, mean this what comes into a driver's segregation apparatus not
The function that tool 2d is switched with 3d image.Therefore this known 3d digital advertisement board, the special advertisement of 3d can only be provided.The present invention carries
Go out a kind of method and apparatus that can simultaneously show 2d and 3d dynamic image, to increase the work(that known 3d digital advertisement board image shows
Can, reach the benefit that advertisement is substantially improved.
Background technology
As shown in Fig. 1～2, it is that known 3d digital advertisement board constitutes the schematic diagram showing with 3d image.This known 3d numeral
Billboard 1, mainly by a lens arra (lenticular) 10,3d dynamically many what comes into a driver's resultant image 20 and a display
Screen 30 is constituted.As shown in Fig. 2 this lens arra (lenticular) 10, by a laminar transparent plastic material institute of tool
Constitute, wherein one side, referred to as 3d structural plane 11, is the structure with multiple column shape lens；And another side, then referred to as image plane
12.Typically, this image plane 12 is in the way of smooth, on this indicator screen 30.This indicator screen 30, shows this 3d
Dynamically many what comes into a driver's resultant image (multi-view combined3d motion image) 20.Dynamically many what comes into a driver's synthesize shadow to this 3d
As 20, it is by n single dynamic vision image (single motion view image) vkSynthesized image is constituted, its
In, n is total what comes into a driver's number, k is what comes into a driver's numbering number, and 0 k n-1.So-called single dynamic vision image, refers to by single photography
The captured 2d dynamic image obtaining of machine.In addition, this n single dynamic vision image vkAcquirement, by n platform camera
Use, and make this each camera system each with different camera angles, obtain this single dynamic vision image v to shootk.
Therefore, two of this arbitrary neighborhood single dynamic vision image vk、vk+1, that is, constitute a 3d dynamic image (3d motion
image).

The detached effect of what comes into a driver's, can be in optimum viewing distance z0N on (optimum viewing distance, ovd) most preferably regards
Point (optimum viewin point, ovp) pkPlace, assumes single dynamic vision image v respectivelyk.
This best view p is located at respectively for left eye l, right eye rk、pk+1On audience for, the left eye of this audience
L, right eye r, are can to watch the single dynamic vision image v a pair with parallax effect respectivelyk、vk+1.Therefore, this audience
Can watch a 3d dynamic image.Herein, for clearly appearing from above-mentioned each display structure and the relation viewing and admiring relevant position, set one
Coordinate system xyz, and make that this x-axis system is set in horizontal direction, y-axis is set in vertical direction, z-axis is then with perpendicular to this 3d structural plane
11 and set and make z=0 be set on this 3d structural plane 11.Then, this above-mentioned correlation viewing location, is positioned at z > 0 area
Domain.
However, the existing naked technology regarding, that is, the technology of automatic stereo (auto-stereoscopic), whether adopts
Lentuclar or the method for parallax grating (parallax barrier), all exist and view and admire degree of freedom (viewing
Freedom the problem limited by), that is, as shown in figure 3, for p at arbitrary best viewk, there is a single visible area 13, in
In this finite region (region as shown in rhombus), audience can watch a preferably 3d dynamic image.So-called preferably 3d
Dynamic image, refers in this single visible area 13, and audience is watched this single dynamic vision image vkIn, it is had
Ghost (cross-talk) degree relatively low.Typically, when ghost ratio is less than 10%, audience is difficult to discover its presence, be with
Can watch a preferably 3d dynamic image.Therefore, using the naked technology regarding, using as 3d digital advertisement board application when, by
In there is the limited disappearance viewing and admiring degree of freedom, can seriously reduce the benefit of advertisement.
