Abstract

The present disclosure relates to a method for transmitting two consecutive pairs of images. The method may include decimating each image with a ratio of 2, assembling the two decimated images of each pair in a composite image, transmitting the composite images, and reconstructing complete images from the composite images. In decimation, the information removed from the images of the first pair may be kept in the images of the second pair, from the spatial point of view, and the complete images may be reconstructed by de-interlacing processing from the composite images.

First claim

The invention claimed is:

1. A method for transmission via circuitry of first and second three-dimensional (3D) images, each 3D image having first and second two-dimensional (2D) images, the method comprising:
operating a decimator circuit for segmenting the first and second 3D images with a ratio of 2, the segmenting comprising
removing lines of a first parity in the first 2D image of the first 3D image,
removing lines of a second parity in the second 2D image of the first 3D image,
removing lines of the second parity in the first 2D image of the second 3D image, and
removing lines of the first parity in the second 2D image of the second 3D image;

assembling the segmented first and second 3D images into a pair of composite images;
transmitting the pair of composite images; and
operating a de-interlace circuit for reconstructing the first and second 3D images from the pair of composite images, the reconstructing comprising
keeping information removed during the segmenting of the first 2D image of the first 3D image from a spatial point of view in the first 2D image of the second 3D image,
keeping information removed during the segmenting of the second 2D image of the first 3D image from the spatial point of view in the second 2D image of the second 3D image, and
reconstructing the first and second 3D images by de-interlacing the pair of composite images.

2. The method according to claim 1 wherein the information removed by the segmenting of the first 2D image is, from the spatial point of view, in a second image of the pair of composite images.

3. The method according to claim 1 wherein the first and second 2D images comprise first and second stereoscopic view images.

4. The method according to claim 1 wherein segmenting the first and second 3D images is based upon at least one of a Top-and-Bottom (TaB) standard and Side-by-Side (SbS) standard.

5. The method according to claim 1 wherein the pair of composite images is based upon the 1080i standard.

6. A method for transmission via circuitry of first and second three-dimensional (3D) images, each 3D image having first and second two-dimensional (2D) images, the method comprising:
operating a decimator circuit for segmenting the first and second 3D images, the segmenting comprising
removing lines of a first parity in the first 2D image of the first 3D image,
removing lines of a second parity in the second 2D image of the first 3D image,
removing lines of the second parity in the first 2D image of the second 3D image, and
removing lines of the first parity in the second 2D image of the second 3D image;

assembling the segmented first and second 3D images into a pair of composite images; and
transmitting the pair of composite images to permit reconstructing of the first and second 3D images from the pair of composite images by de-interlacing the pair of composite images, the reconstructing comprising
keeping information removed during the segmenting of the first 2D image of the first 3D image from a spatial point of view in the first 2D image of the second 3D image, and
keeping information removed during the segmenting of the second 2D image of the first 3D image from the spatial point of view in the second 2D image of the second 3D image.

7. The method according to claim 6 wherein information from segmentation of the first 2D image is in the pair of composite images.

8. The method according to claim 6 wherein
the first parity comprises even numbered lines; and wherein the second parity comprises
odd numbered lines.

9. The method according to claim 8 wherein the segmented even and odd numbered lines from the first 2D image are embedded respectively in first and second images of the pair of composite images.

10. The method according to claim 6 wherein the first and second 2D images comprise first and second stereoscopic view images.

11. The method according to claim 6 wherein segmenting the first and second 2D images is based upon at least one of a Top-and-Bottom (TaB) standard and Side-by-Side (SbS) standard.

12. The method according to claim 6 wherein the pair of composite images is based upon the 1080i standard.

13. A method for transmitting first and second three-dimensional (3D) images, each 3D image having first and second two-dimensional (2D) images, the method comprising:
operating a decimator circuit for segmenting the first and second 3D images, the segmenting comprising
removing even numbered lines in the first 2D image of the first 3D image,
removing odd numbered lines in the second 2D image of the first 3D image,
removing odd numbered lines in the first 2D image of the second 3D image, and
removing even numbered lines of in the second 2D image of the second 3D image;

assembling the segmented first and second 3D images into a pair of composite images; and
transmitting the pair of composite images to permit reconstructing of the first and second 3D images from the pair of composite images by de-interlacing the pair of composite images, the reconstructing comprising
keeping information removed during the segmenting of the first 2D image of the first 3D image from a spatial point of view in the first 2D image of the second 3D image, and
keeping information removed during the segmenting of the second 2D image of the first 3D image from the spatial point of view in the second 2D image of the second 3D image.

14. The method according to claim 13 wherein the information removed by the segmenting of the first 2D image is, from the spatial point of view, in a second image of the pair of composite images.

15. The method according to claim 13 wherein the first and second 2D images comprise first and second stereoscopic view images.

16. The method according to claim 13 wherein segmenting the first and second 3D images is based upon at least one of a Top-and-Bottom (TaB) standard and Side-by-Side (SbS) standard.

17. The method according to claim 13 wherein the pair of composite images is based upon the 1080i standard.
