Abstract

Disclosed are a terminal for increasing visual comfort sensation of a 3D object and a control method thereof. To this end, a control method of a terminal includes displaying the 3D content on a screen of the terminal. When a specific 3D object included in the 3D content moves in a specific direction on the screen, a rendering scheme of the specific 3D object is changed. The specific 3D object is displayed on the screen using the changed rendering scheme.

Claims

1. A control method of a terminal providing a 3D content, the method comprising:

displaying the 3D content on a screen of the terminal;

changing a rendering scheme of a specific 3D object included in the 3D content when the specific 3D object moves in a specific direction on the screen; and

displaying the specific 3D object on the screen using the changed rendering scheme.

2. The method of claim 1, wherein the 3D content is a 3D web-page.

3. The method of claim 1, wherein the specific direction is a direction facing an edge on the screen from a previous position of the specific 3D object movement.

4. The method of claim 1, wherein the changing of the rendering scheme is performed by changing the image depth of the specific 3D object based on a position of the specific 3D object on the screen.

5. The method of claim 4, wherein the image depth is decreased when the position of the specific 3D object on the screen approaches the edge on the screen.

6. The method of claim 1, wherein the changing of the rendering scheme comprises:

determining whether or not the specific 3D object is out of a reference area based on the movement of the specific 3D object; and

changing the rendering scheme when the specific 3D object is out of the reference area.

7. The method of claim 6, wherein the reference area is determined based on a degree of visual fatigue of a user of the terminal.

8. The method of claim 1, wherein the rendering scheme is a scheme in which a 3D effect is implemented based on first and second images included in the specific 3D object, and the image centers of the first and second images are positioned on the screen while being spaced apart from each other at a distance corresponding to the image depth of the specific 3D object.

9. The method of claim 8, wherein the image center of the first image is closer to the edge on the screen than that of the second image.

10. The method of claim 8, wherein the changing of the rendering scheme comprises:

determining whether or not a portion of the first image is out of the screen due to the movement of the specific 3D object; and

changing the rendering scheme of the specific 3D object when the portion is out of the screen.

11. The method of claim 10, wherein the changing of the rendering scheme is performed by decreasing the image depth of the specific 3D object.

12. The method of claim 11, wherein the portion is positioned on the screen based on the decrease in the image depth.

13. The method of claim 10, wherein the changing of the rendering scheme is performed by not displaying a portion of the second image, corresponding to the portion of the first image.

14. A terminal comprising:

a display unit configured to display a 3D content on a screen of the terminal; and

a control unit configured to change a rendering scheme of a specific 3D object included in the 3D content when the specific 3D object moves in a specific direction on the screen, and control the display unit so that the specific 3D object is displayed on the screen using the changed rendering scheme.

15. The terminal of claim 14, wherein the specific direction is a direction facing an edge on the screen from a previous position of the specific 3D object movement.

16. The terminal of claim 14, wherein the rendering scheme is changed by changing the image depth of the specific 3D object based on the position of the specific 3D object on the screen.

17. The terminal of claim 14, wherein the rendering scheme is a scheme in which a 3D effect is implemented based on first and second images included in the specific 3D object, and the image centers of the first and second images are positioned on the screen while being spaced apart from each other at a distance corresponding to the image depth of the specific 3D object.

18. The terminal of claim 17, wherein the rendering scheme is changed when a portion of the first image is out of the screen due to the movement of the specific 3D object.

19. The terminal of claim 18, wherein the rendering scheme is changed by decreasing the image depth of the specific 3D object.

20. The terminal of claim 18, wherein the rendering scheme is changed by not displaying a portion of the second image, corresponding to the portion of the first image.
