Abstract

A method for displaying a three-dimensional (3D) image in a display panel of a 3D display device is provided. The method includes generating M images corresponding to a maximum disparity in response to input two-dimensional (2D) images and disparity information of the respective 2D images. The 2D images include a left-side image and a right-side image. The method further includes selecting N images from among the M images, providing the selected N images to a display unit, and displaying the provided N images using the display panel.

Claims

1. A method for displaying a three-dimensional (3D) image in a display panel of a 3D display device comprising:

generating M images corresponding to a maximum disparity in response to received two-dimensional (2D) images including left-side and right-side images and disparity information of the respective left-side and right-side images,

selecting N images from among the M images;

providing the selected N images to the display panel; and

displaying the provided N images using the display panel,

wherein the generating of the M images comprises;

determining a number of intermediate images that is proportional to a range of the maximum disparity;

generating a plurality of first images using the left-side image and a shift value corresponding to the number of intermediate images;

generating a plurality of second images using the right-side image and the shift value corresponding to the number of intermediate images; and

generating the M images using the plurality of first images and the plurality of second images.

2. The method of claim 1, further comprising:

measuring a user position, wherein the selecting of the N images is performed in response to the user position.

3. The method of claim 2, wherein the generating of the M images further comprises:

receiving the 2D images and the disparity information of the respective left-side and right-side images; and

determining a shift value in response to the disparity information of the respective left-side and right-side images.

4. The method of claim 3, wherein the determining of the shift value comprises:

measuring the maximum disparity in response to the disparity information of the left-side and right-side images;

determining the number of intermediate images to be generated in response to the maximum disparity; and

storing the shift value corresponding to the number of intermediate images to be generated.

5. The method of claim 4, wherein the generating of the plurality of first images comprises:

filtering a noise of the disparity information of the left-side image;

shifting the left-side image by the number of intermediate images in response to the shift value; and

performing a hole processing on a hole of the shifted left-side image,

wherein the generating of the plurality of second images comprises;

filtering a noise of the disparity information of the right-side image;

shifting the right-side image by the number of intermediate images in response to the shift value; and

performing a hole processing on a hole of the shifted right-side image.

6. The method of claim 5, wherein the performing of the hole processing on the hole of the shifted left-side image is performed using an image background color and the shifted right-side image.

7. The method of claim 5, wherein the performing the hole processing on the hole of the shifted right-side image is performed using an image background color and the shifted left-side image.

8. The method of claim 5, wherein the plurality of first images includes the left-side image and images obtained by the first performing of the hole processing on the hole of the shifted left-side image.

9. The method of claim 5, wherein the plurality of second images includes the right-side image and images obtained by the second performing of the hole processing on the hole of the shifted right-side image.

10. The method of claim 5, wherein the M images are generated using the left-side and right-side images, and images obtained by the first performing of the hole processing on the hole of the shifted left-side image and the second performing of the hole processing on the hole of the shifted right-side image.

11. The method of claim 1, wherein a value of M is greater than or equal to a value of N.

12. The method of claim 1, wherein a value of M is 15 and a value of N is 9.

13. The method of claim 12,

wherein the selected 9 images correspond to 9 continuous views from a leftmost view corresponding to the left-side image, from among the 15 images upon determining that the user position is measured within five views from the leftmost view.

14. The method of claim 12,

wherein the selected 9 images correspond to 9 continuous views from a rightmost view corresponding to the right-side image, from among the 15 images upon determining that the user position is measured within five views from the rightmost view.

15. The method of claim 12,

wherein the selected 9 images correspond to 9 continuous views from a fourth view on the left side or a fourth view on the right side on the basis of the user position, from among the 15 images upon determining that the user position is measured at a view greater than five views from a leftmost view corresponding to the left-side image and greater than five views from a rightmost view corresponding to the right-side image.

16. The method of claim 12,

wherein the generating of the M images comprises:

receiving the 2D images including a left-side image, a right-side image, and a center image, and disparity information of the respective left-side, right-side, and center images;

determining a first shift value in response to the disparity information of the respective left-side and center images;

determining a second shift value in response to the disparity information of the respective right-side and center images;

generating a plurality of first images using the left-side image and the disparity information of the left-side image and the first shift value;

generating a plurality of second images using the center image and the disparity information of the center image and the first shift value;

generating a plurality of third images using the center image and the disparity information of the center image and the second shift value;

generating a plurality of fourth images using the right-side image and the disparity information of the right-side image and the second shift value;

generating a plurality of fifth images using the plurality of first images and the plurality of second images;

generating a plurality of sixth images using the plurality of third images and the plurality of fourth images;

receiving the plurality of fifth images and the plurality of sixth images; and

selecting the N images from among the M images other than a duplicated image of the input images, according to the user position, wherein the N images correspond to N continuous views.

17. The method of claim 10, wherein one image of the M images is generated by composing one of the plurality of first images and one of the plurality of second images, and weights are given to the hole-processed left-side image or the hole-processed right-side image in inverse proportion to a ratio of a distance between a particular view corresponding to the one image and a leftmost view and a distance between the particular view and a rightmost view.

18. The method of claim 1, wherein the number of intermediate images is increased by one when the range of the maximum disparity is increased by ten.
