Abstract

A method for processing images in a display device outputting 3-dimensional (3D) contents and a display device using the same are disclosed herein. The method includes the steps of adjusting output positions of one of a first video image and a second video image, adjusting an angle of one of the first video image and the second video image, and outputting the first video image and the second video image in a 3D format.

Claims

1. A method of outputting images from a 3-dimensional (3D) display device, comprising:

adjusting output positions of one of a first video image and a second video image;

adjusting an angle of one of the first video image and the second video image; and

outputting the first video image and the second video image in a 3D format.

2. The method of claim 1, further comprising:

receiving information on an output position and information on an output angle through a user interface.

3. The method of claim 1, further comprising:

determining a user viewing distance, the user viewing distance corresponding to a distance between a user and the 3D display device; and

calculating a difference value between the determined user viewing distance and an optimal viewing distance, and, when the calculated difference value is greater than or equal to a first reference value, adjusting an output position of 3D image data, the 3D image data being an output subject.

4. The method of claim 3, wherein the step of calculating a difference value between the determined user viewing distance and an optimal viewing distance, and, when the calculated difference value is greater than or equal to a first reference value, adjusting an output position of 3D image data, the 3D image data being an output subject, comprises:

calculating a 3D effect value of the 3D image data and, when the calculated 3D effect value is greater than or equal to a second reference value, adjusting an output position of the 3D image data.

5. The method of claim 3, wherein the step of calculating a difference value between the determined user viewing distance and an optimal viewing distance, and, when the calculated difference value is greater than or equal to a first reference value, adjusting an output position of 3D image data, the 3D image data being an output subject, comprises:

adjusting a depth value of the 3D image data in accordance with the calculated difference value.

6. The method of claim 5, wherein the step of adjusting a depth value of the 3D image data in accordance with the calculated difference value, comprises:

when the user viewing distance is longer than the optimal viewing distance by the first reference value or more, increasing a depth value of the 3D image data, the 3D image data being the output subject.

7. The method of claim 5, wherein the step of adjusting a depth value of the 3D image data in accordance with the calculated difference value, comprises:

when the user viewing distance is shorter than the optimal viewing distance by the first reference value or more, decreasing a depth value of the 3D image data, the 3D image data being the output subject.

8. The method of claim 3, wherein the step of calculating a difference value between the determined user viewing distance and an optimal viewing distance, and, when the calculated difference value is greater than or equal to a first reference value, adjusting an output position of 3D image data, the 3D image data being an output subject, comprises:

adjusting a tilt value of the 3D image data in accordance with the calculated difference value.

9. The method of claim 8, wherein the adjusting a tilt value of the 3D image data in accordance with the difference value, comprises:

when the user viewing distance is shorter than the optimal viewing distance by the first reference value or more, decreasing a tilt value of the 3D image data, the 3D image data being the output subject.

10. The method of claim 8, wherein the adjusting a tilt value of the 3D image data in accordance with the difference value, comprises:

when the user viewing distance is longer than the optimal viewing distance by the first reference value or more, increasing a tilt value of the 3D image data, the 3D image data being the output subject.

11. A 3-dimensional (3D) display device, comprising:

an output position adjusting unit configured to determine a user viewing distance between a user and the 3D display device, to calculate a difference value between the determined user viewing distance and an optimal viewing distance and, when the difference value is greater than or equal to a first reference value, to adjust an output position of a 3D image, the 3D image being an output subject; and

a 3D formatter configured to output the 3D image having its output position adjusted in a 3D format.

12. The 3D display device of claim 11, further comprising:

a user input unit configured to receive the user viewing distance from a predetermined user interface.

13. The 3D display device of claim 11, wherein the output position adjusting unit calculates a 3D effect value of the 3D image data and, when the calculated 3D effect value is greater than or equal to a second reference value, adjusts an output position of the 3D image data.

14. The 3D display device of claim 13, wherein the output position adjusting unit calculates a depth value of the 3D image data corresponding to a predetermined area of the 3D image data and, when the depth value is greater than or equal to the second reference value, adjusts the output position of the 3D image data.

15. The 3D display device of claim 11, wherein the output position adjusting unit adjusts a depth value of the 3D image data in accordance with the difference value.

16. The 3D display device of claim 15, wherein, when the user viewing distance is longer than the optimal viewing distance by the first reference value or more, the output position adjusting unit increases a depth value of the 3D image data, the 3D image data being the output subject.

17. The 3D display device of claim 15, wherein, when the user viewing distance is shorter than the optimal viewing distance by the first reference value or more, the output position adjusting unit decreases a depth value of the 3D image data, the 3D image data being the output subject.

18. The 3D display device of claim 11, wherein the output position adjusting unit adjusts a tilt value of the 3D image data in accordance with the difference value.

19. The 3D display device of claim 18, wherein, when the user viewing distance is shorter than the optimal viewing distance by the first reference value or more, the output position adjusting unit decreases a tilt value of the 3D image data, the 3D image data being the output subject.

20. The 3D display device of claim 18, wherein, when the user viewing distance is longer than the optimal viewing distance by the first reference value or more, the output position adjusting unit increases a tilt value of the 3D image data, the 3D image data being the output subject.
