Abstract

A three dimensional system including rendering with variable displacement.

Claims

1. A method for conversion using a processor of a series of two dimensional images into a series of three dimensional images comprising:

(a) said processor receiving said two dimensional images where each of said series of two dimensional images are from a same viewpoint, where said series of two dimensional images do not include any images from a viewpoint other than said same viewpoint;

(b) said processor processing said two dimensional images all of which are from said same viewpoint and do not include any images from a viewpoint other than said same viewpoint to determine a depth map associated with said two dimensional images where all of said series of two dimensional images are from said same viewpoint, where said series of two dimensional images do not include any images from a viewpoint other than said same viewpoint;

(c) said processor modifying at least four non-zero depths in said depth map in such a manner that said at least four non-zero depths of said depth map are changed from a first non-zero depth to a second non-zero depth based upon a concentration of a plurality of depths of said depth map;

(d) processing said modified depth map to render said two dimensional images all of which are from the same viewpoint and do not include any images from a viewpoint other than said same viewpoint on a display as said three dimensional images;

(e) rendering said two dimensional images all of which are from the same viewpoint and do not include any images from a viewpoint other than said same viewpoint based upon said processed depth map on a display.

2. The method of claim 1 wherein said modifying expands a first range of depths of said depth map to a second range of depths of said depth map, where said second range is greater than said first range.

3. The method of claim 2 wherein said first range of depths is a substantial percentage of a total depth range of said depth map.

4. The method of claim 3 wherein said second range is substantially all of said total depth range of said depth map.

5. The method of claim 4 wherein said second range is all of a total depth range of said depth map.

6. The method of claim 2 wherein said modifying is done in a linear manner.

7. The method of claim 2 wherein said modifying is done is a non-linear manner.

8. The method of claim 1 wherein said modifying compresses a first range of depths of said depth map to a second range of depths of said depth map, where said second range is smaller than said first range.

9. The method of claim 8 wherein said first range of depths is a substantial percentage of the total depth range of said depth map.

10. The method of claim 9 wherein said second range is substantially all of said total depth range of said depth map.

11. The method of claim 10 wherein said second range is all of said total depth range of said depth map.

12. The method of claim 8 wherein said modifying is done in a linear manner.

13. The method of claim 8 wherein said modifying is done is a non-linear manner.
