Abstract

A three-dimensional (3D) image display system includes a profile information provider configured to provide profile information defining a hardware characteristic of a 3D image display device, and a 3D image reproducer configured to collect information of the hardware characteristic of the 3D image display device from the profile information provider and render image content according to the profile information.

First claim

What is claimed is:

1 . A three-dimensional (3D) image display system comprising:
a profile information provider configured to provide profile information defining a hardware characteristic of a 3D image display device; and a 3D image reproducer configured to collect information of the hardware characteristic of the 3D image display device from the profile information provider and render image content according to the profile information.

2 . The 3D image display system of claim 1 , wherein the profile information includes the number of pixels in width, the number of pixels in height, the number of viewpoints, and an index map of the 3D image display device.

3 . The 3D image display system of claim 2 , wherein the index map is information about a viewpoint arranged on each sub-pixel of the 3D image display device.

4 . The 3D image display system of claim 1 , wherein the profile information includes the number of pixels in width, the number of pixels in height, the number of viewpoints, a width size, a height size, a distance between neighboring viewing zones of the 3D image display device, and a distance between the 3D image display device and an observer.

5 . The 3D image display system of claim 1 , wherein the 3D image reproducer includes:
a rendering context initializer configured to perform initialization necessary for rendering by using the profile information; a setting unit for a renderer and a shader; a camera setting unit configured to set a camera position of each viewpoint for rendering each scene of respective viewpoints represented by the 3D image display device; a buffer initializer configured to set up and initialize a buffer configured to store a result of rendering each viewpoint image to be used in the shader; a content loader configured to read image content to be played by the 3D image display device; and a rendering unit configured to render the image content.

6 . The 3D image display system of claim 5 , wherein the rendering context initializer includes a setting of the number of pixels for rendering images of each of the viewpoint.

7 . The 3D image display system of claim 5 , wherein the setting unit for the renderer and the shader adds a light source and sets a viewport when setting the renderer.

8 . The 3D image display system of claim 1 , wherein:
the profile information provider is connected to the 3D image display device; and the 3D image reproducer is connected to the content provider and receives the image content.

9 . The 3D image display system of claim 1 , wherein the image content is auto-stereoscopic multi-view image content or super multi-view image content.

10 . A 3D image display method comprising:
reading a display profile which is hardware characteristic information of a 3D image display device; initializing a rendering context by using the profile; setting a renderer and a shader; setting a camera position of each viewpoint for rendering each scene of respective viewpoints represented by the 3D image display device; setting and initializing a buffer configured to store a result of rendering image of each viewpoint used in the shader; loading image content to be played by the 3D image display device; and rendering the image content.

11 . The 3D image display method of claim 10 , wherein the profile information includes the number of pixels in width, the number of pixels in height, the number of viewpoints, and an index map of the 3D image display device.

12 . The 3D image display method of claim 11 , wherein the index map is information about a viewpoint arranged on each sub-pixel of the 3D image display device.

13 . The 3D image display method of claim 10 , wherein the profile information includes the number of pixels in width, the number of pixels in height, the number of viewpoints, a width size, a height size, a distance between neighboring viewing zones of the 3D image display device, and a distance between the 3D image display and an observer.

14 . The 3D image display method of claim 10 , wherein the initializing of the rendering context includes setting the number of pixels for rendering images of each of the viewpoint.

15 . The 3D image display method of claim 10 , wherein the setting of the renderer and the shader includes adding a light source and setting a viewport when setting the renderer.

16 . The 3D image display method of claim 10 , wherein the image content is auto-stereoscopic multi-view image content or super multi-view image content.
