AMENDED CLAIMS

received by the International Bureau on 02 November 2010 (02.11.2010)

1. Λ method for generating a left-eye image and a right-eye image usable to create a 3D effect, the method comprising:

(a) receiving a 3D-compatible image having a left-eye portion and a right-eye portion, wherein:

the 3D-compatible image comprises an overlay overlaying part of at least one of the left-eye portion and the right-eye portion;

the overlay has information; and

the left-eye portion and the right-eye portion do not contain identical overlay information;

(b) generating the left-eye image based on the left-eye portion and the overlay; and

(c) generating the right-eye image based on the right-eye portion and the overlay, wherein

both of the left-eye and right-eye images include the same information from the overlay.

2. The invention of claim 1, wherein:

the overlay corresponds to closed captioning having characters and a background.

3. The invention of claim 2, further comprising recreating the characters and the background in both the left-eye and right-eye images, wherein:

the recreated characters in the left-eye and right-eye images are substantially the same dimensions as the corresponding characters of the closed captioning overlay; and

the recreated backgrounds in the left-eye and right-eye images are larger than the background of the closed captioning overlay.

4. The invention of claim 2, further comprising recreating the characters and the background in both the left-eye and right-eye images, wherein:

the recreated characters in the left-eye and right-eye images appear stretched relative to the corresponding characters of the closed captioning overlay; and

the recreated backgrounds in the left-eye and right-eye images appear stretched relative to the background of the closed captioning overlay.

5. The invention of claim 1 , wherein:

the left-eye portion forms one of a top portion and a bottom portion of the 3D-compatible jmagc;

the right-eye portion forms the other of the top portion and the bottom portion of the 3D-comρatible image;

one of the left-eye and right-eye portions has all information of the overlay; and the other of the left-eye and right-eye portions has none of the information of the overlay.

6. The invention of claim 1 , wherein :

the left-eye portion forms one of a left portion and a right portion of the 3D-compatible image; and

the right-eye portion forms the other of the left portion and the right portion of the 3D-compatible image.

7. The invention of claim 6, wherein:

one of the left-eye and right-eye portions has all of the information of the overlay; and

the other of the left-eye and right-eye portions bas none of the information of the overlay.

8. The invention of claim 6, wherein each of the left-eye and right-eye portions has a different part of the information of the overlay.

9. The invention of claim 1, further comprising determining that the 3D-compatible image comprises the overlay.

10. The invention of claim 9, wherein:

the 3D-compatible image comprises a separation region separating the left-eye and right-eye portions; and

the determination whether the 3D-compatible image comprises the overlay is performed only if the separation region is detected.

11. The invention of claim 1 , further comprising displaying the left-eye and right-eye images to create the 3D effect

12. The invention of claim 1, wherein:

the overlay is a 2D image generated by a set-top box (STB); and

the STB lays the overlay over the 3D-compatible image without recognizing the 3D-compatible image as 3D compatible.

13. An image processor, comprising:

(a) an overlay detector adapted to receive a 3D-compatible image having a left-eye portion and a right-eye portion, wherein:

the 3D-compatible image comprises an overlay overlaying part of at least one of the left-eye portion and the right-eye portion;

the overlay has information; and

the left-eye portion and the right-eye portion do not contain identical overlay information; and

(b) a display controller adapted to:

generate a left-eye image based on the left-eye portion and the overlay; and generate a rigbt-eye image based on the right-eye portion and the overlay, wherein:

both of the left-eye and right-eye images include the same information from the overlay; and

the left-eye and right-eye image are usable to create a 3D effect.

14. The invention of claim 13, wherein:

the overlay corresponds to closed captioning having characters and a background.

15. The invention of claim 14, wherein:

the display controller is adapted to recreate the characters and the background in both the left-eye and right-eye images;

the recreated characters in the left-eye and rjght-eye images are substantially the same dimensions as the characters of the closed captioning overlay; and

the recreated backgrounds in the left-eye and right-eye images are larger than the background of the closed captioning overlay.

16. The invention of claim 14, wherein:

the display controller is adapted to recreate the characters and the background in both the left-eye and right-eye images, wherein:

the recreated characters in the left-eye and right-eye images appear stretched relative to the characters of the closed captioning overlay; and

the recreated backgrounds in the left-eye and right-eye images appear stretched relative to the background of the closed captioning overlay.

17. The invention of claim 13, wherein the overlay detector is further adapted to determine that the 3D-corapatible image comprises the overlay.

18. The invention of claim 17, wherein:

the 3D-compatible image comprises a separation region separating the left-eye and right-eye portions;

the image processor is adapted to detect the separation region; and

the overlay detector determines whether the 3D-compatib3e image comprises the overlay only if the separation region is detected.

19. A device for generating a left-eye image and a right-eye image usable to create a 3D effect, the device comprising:

(a) means for receiving a 3D-compatible image having a left-eye portion and a right-eye portion, wherein:

the 3D-compatible image comprises an overlay overlaying part of at least one of the left-eye portion and the right-eye portion;

the overlay has information; and

the left-eye portion and the right-eye portion do not contain identical overlay information;

(b) means for generating the left-eye image based on the left-eye portion and the overlay; and

(c) means for generating the right-eye image based on the right-eye portion and the overlay, wherein both of the left-eye and right-eye images include the same information from the overlay.
