Abstract

A method of encoding a 2D image with an associated depth map, said 2D image having a plurality of frames making up the 2D image and each frame having a odd and even field, wherein the method includes the step of recording the associated depth map in at least a portion of the odd or even field.

Claims

1. A method of encoding a 2D image with an associated depth map, said 2D image having a plurality of frames making up said 2D image and each frame having a odd and even field, wherein said method includes the step of recording said associated depth map in at least a portion of said odd or even field.

2. The method as claimed in claim 1, wherein said depth map is recorded in said odd field.

3. The method as claimed in claim 1, wherein said depth map is recorded in said even field.

4. The method as claimed in claim 2, further including the step of interpolating odd lines for each frame from image data stored in said even field.

5. The method as claimed in claim 3, further including the step of interpolating even lines for each frame from image data stored in said odd field.

6. The method as claimed in claim 1, wherein said depth map is recorded in a predetermined area of said odd and even field.

7. The method as claimed in claim 1, wherein said depth map is recorded in a fraction n of lines of said image.

8. The method as claimed in claim 7, wherein said depth map is at least partially recorded in each fields chrominance channel.

9. The method as claimed in claim 7, wherein fraction n is devisable by 16.

10. The method as claimed in claim 1, further including the step of digitally compressing said encoded signal in interlaced mode.

11. The method as claimed in claim 1, further including the step of digitally compressing said encoded signal in progressive mode.

12. The method as claimed in claim 1, further including the step of:

copying chrominance components of said 2D image into chrominance components of said depth map.

13. The method as claimed in claim 12, further including the step of digitally compressing said signal in progressive mode.

14. The method as claimed in claim 12, further including the step of digitally compressing said signal in interlaced mode.

15. An image including at least one frame, said frame including an odd field and an even field, wherein an associated depth map is recorded in at least a portion of said odd and/or even field.
