Description

Method and device for simultaneously displaying 2D and 3D motion images

For the conventional 3D Digital Signage, a view separation device composed of Lenticular is generally used to display a naked-view 3D motion image to provide a 3D advertisement. The conventional 3D digital signage is limited by mass production technology and cost, and generally can only use a display with a smaller screen size and a fixed view separation device. The term "fixed view separation device" means that the view separation device does not have the function of switching between 2D and 3D images. Therefore, the conventional 3D digital signage can only provide 3D-specific advertisements. The invention provides a method and a device for simultaneously displaying 2D and 3D motion images, so as to increase the function of the conventional 3D digital kanban image display, thereby greatly improving the efficiency of the advertisement.

As shown in FIGS. 1 and 2, a schematic diagram of a conventional 3D digital signboard and a 3D image display is shown. The conventional 3D digital signage 1 is mainly composed of a Lenticular 10, a 3D dynamic multi-view synthetic image 20, and a display screen 30. As shown in FIG. 2, the Lenticular 10 is composed of a sheet-like transparent plastic material, one side of which is referred to as a 3D structural surface 11 and has a structure of a plurality of cylindrical lenses; and the other side is called For the image surface 12. Typically, the image surface 12 is mounted on the display screen 30 in a flat manner. The display screen 30 displays the 3D dynamic multi-view combined image (Multi-View Combined 3D Motion Image) 20. The 3D dynamic multi-view composite image 20 is composed of n single motion view images (V _K ), wherein n is the total number of views and k is the number of view numbers. And 0≦k≦n-1. The so-called single dynamic view image refers to a 2D motion image captured by a single camera. Further, the n made in a single dynamic view image of V _K, by using the system of n cameras, each camera and enabling the system to each of the different camera angles, to obtain the captured in a single dynamic view image V _k . Therefore, the two adjacent single dynamic view images V _k , V _k+1 constitute a 3D motion image.

As shown in FIG. 2, for the 3D dynamic multi-view synthesized image 20, the n best of the optimal viewing distance Z ₀ (Optimum Viewing Distance, OVD) can be obtained by the view separation of the Lenticular 10. viewpoint (Optimum Viewin Point, OVP) P k , the individual presents in a single dynamic view image V _k.

For the viewer whose left eye L and right eye R are located on the optimal viewpoint P _k , P _k+1 , the viewer's left eye L and right eye R can be individually viewed to have a parallax effect. The single dynamic view image V _k , V _k+1 . Therefore, the viewer can view a 3D motion picture. Here, in order to clearly show the relationship between each display structure and the viewing-related position, a calibration system XYZ is set, and the X-axis system is set in the horizontal direction, the Y-axis is set in the vertical direction, and the Z-axis is perpendicular to the 3D structure. The surface 11 is set, and Z=0 is set on the 3D structural surface 11. Therefore, the related viewing position is located in the area of Z>0.

However, the existing technology of naked vision, that is, the technology of Auto-Stereoscopic, whether using Lentuclar or Parallel Barrier, has the problem of limited viewing freedom (Viewing Freedom), that is, as shown in the figure. As shown in Fig. 3, for any optimal viewpoint P _k , there is a single visible area 13 in which a viewer can view a preferred 3D motion picture. The preferred 3D motion picture refers to the fact that the single dynamic view image V _k is viewed by the viewer in the single viewable area 13 and has a low degree of cross-talk. Generally, when the ghost ratio is less than 10%, the viewer is not aware of its existence, so that a better 3D motion picture can be viewed. Therefore, the use of the technology of naked vision, as a 3D digital signage application, due to the lack of limited viewing freedom, will seriously reduce the effectiveness of advertising.

In view of the above-mentioned deficiencies, the present invention provides a method and apparatus for simultaneously displaying 2D and 3D motion images, which can increase the function of 3D digital kanban image display and greatly improve the effectiveness of advertising.

The method mainly uses a first light source, a first image surface, a second image surface, and a second light source to simultaneously project the first light source and the second light source to the first image surface. And the method of the second image surface to achieve the purpose of simultaneously displaying a 2D motion and a 3D motion image.

The device mainly utilizes a first 2D moving image light source, a first image surface, a transparent substrate, a second image surface, and a second 3D dynamic multi-view synthetic image light source, wherein the first 2D The dynamic image light source can project a 2D moving image light; the second 3D dynamic multi-view synthetic image light source can project a 3D dynamic multi-view synthetic image light; the first image surface has a parallax grating a structure, the light-shielding element in the parallax barrier structure, the surface of which is composed of a material having light reflection and light scattering; and the second image surface has a rear projection screen structure, the structure is composed of light transmission and light The material of the scattering material; the first image surface and the second image surface can be individually mounted on the transparent substrate by a process technology such as alignment, coating, printing, photolithography, laser engraving, surface atomization, and the like. On both sides. Through the above The method is characterized in that the 2D moving image light and the 3D dynamic multi-view combined image light are simultaneously projected onto the first image surface and the second image surface, and the device can simultaneously display one The purpose of dynamic 2D and a dynamic 3D motion picture.

For the viewer who is in front of the 3D digital signage formed by the method and the device, the 2D image can be viewed at any position, and at the optimal viewing distance, the 3D dynamic can be viewed. A 3D motion image composed of a view synthesis image. Therefore, when the viewer is standing at the best viewing distance, 2D and 3D motion images can be viewed simultaneously.

In summary, the 3D digital signage formed by the method and the device not only provides the function of the 3D digital signboard, but also retains the function of the original 2D digital signage. Therefore, in addition to achieving unprecedented visual effects, it can also create the benefits of unlimited advertising.
