Abstract

An image display apparatus and an operating method thereof are provided. The image display apparatus may determine the location of a user, and may display a 3D object in consideration of the location of the user. If the user moves his or her eyes or hands, the location of the 3D object may change accordingly.

Claims

1. A method of displaying a three-dimensional (3D) object by an image display apparatus, the method comprising:

detecting, by the image display apparatus, a location of an object outside of the image display apparatus; and

displaying, by the image display apparatus, the 3D object at a predetermined position relative to the detected location.

2. The method of claim 1, further comprising:

determining the predetermined position based on content of the 3D object.

3. The method of claim 1, wherein the predetermined position is at least one of a position directly in front of the detected location, a position to the left or right of the detected position, and a position above or below the detected position.

4. The method of claim 1, wherein the 3D object includes one of a static image and a moving image.

5. The method of claim 1,

wherein the step of detecting a location of an object includes detecting a first location of a first object and detecting a second location of a second object;

and

wherein the step of displaying the 3D object at a predetermined position includes displaying a first 3D object at a predetermined position relative to the first detected location and displaying a second object 3D object at a predetermined position relative to the second detected location.

6. The method of claim 1, wherein the step of detecting a location of an object outside of the image display apparatus comprises one of:

detecting an observer'"'"'s height;

detecting an observer'"'"'s eye level; and

detecting an observer'"'"'s hand level.

7. The method of claim 1, further comprising:

detecting a motion in or near the displayed 3D object.

8. The method of claim 7, further comprising:

changing the 3D object in response to the detected motion.

9. The method of claim 8,

wherein the step of detecting a motion includes detecting the motion relative to one of plural subsections of the 3D object.

10. The method of claim 7, wherein the step of detecting a motion in or near the displayed 3D object comprises:

detecting a hand motion in or near the displayed 3D object; and

identifying the hand motion by comparing the detected hand motion to a database of stored hand motions.

11. The method of claim 10, further comprising:

changing the predetermined position based on the identified hand motion.

12. An image display apparatus, comprising:

a tuner;

a display;

a detector; and

a controller operatively connected to the tuner, the display and the detector, the controller configured to

detect a location of an object outside of the image display apparatus; and

display a 3D object at a predetermined position relative to the detected location.

13. The image display apparatus of claim 12, wherein the controller is configured to determine the predetermined position based on content of the 3D object.

14. The image display apparatus of claim 12, wherein the predetermined position is at least one of a position directly in front of the detected location, a position to the left or right of the detected position, and a position above or below the detected position.

15. The image display apparatus of claim 12, wherein the 3D object includes one of a static image and a moving image.

16. The image display apparatus of claim 12, wherein the controller is configured to:

detect a first location of a first object and detect a second location of a second object; and

display a first 3D object at a predetermined position relative to the first detected location and display a second object 3D object at a predetermined position relative to the second detected location.

17. The image display apparatus of claim 12, wherein the controller is configured to detect one of:

an observer'"'"'s height;

an observer'"'"'s eye level; and

an observer'"'"'s hand level.

18. The image display apparatus of claim 12, wherein the controller is configured to detect a motion in or near the displayed 3D object.

19. The image display apparatus of claim 18, wherein the controller is configured to change the 3D object in response to the detected motion.

20. The image display apparatus of claim 19, wherein the controller is configured to detect the motion relative to one of plural subsections of the 3D object.

21. The image display apparatus of claim 18, wherein the controller is configured to:

detect a hand motion in or near the displayed 3D object; and

identify the hand motion by comparing the detected hand motion to a database of stored hand motions.

22. The image display apparatus of claim 21, wherein the controller is configured to change the predetermined position based on the identified hand motion.
