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.

Claims

1. A method for transmission of a three-dimensional (3D) image as first and second two-dimensional (2D) images, the method comprising:

segmenting the first and second 2D images into segmented images, the segmenting comprising;

segmenting even numbered lines and odd numbered lines from the first 2D image to respectively form a first segmented image and a second segmented image;

segmenting even numbered lines and odd numbered lines from the second 2D image to respectively form a third segmented image and a fourth segmented image;

assembling one of the first segmented image or the second segmented image with one of the third segmented image or the fourth segmented image into a first composite image, and assembling the other of the first segmented image or the second segmented image with the other of the third segmented image or the fourth segmented image into a second composite image, the first composite image and the second composite image defining a pair of composite images; and

transmitting the pair of composite images to permit reconstructing of the 3D image from the pair of composite images by de-interlacing the pair of composite images.

2. The method according to claim 1 comprising storing information from segmentation of the first 2D image in the pair of composite images.

3. The method according to claim 1 comprising embedding first segmented image and the second segmented image respectively into the first and second composite images of the pair of composite images.

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

5. The method according to claim 1 wherein segmenting the first and second 2D images is based upon a Top-and-Bottom (TaB) standard.

6. The method according to claim 1 wherein segmenting the first and second 2D images is based upon a Side-by-Side (SbS) standard.

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

8. A method for reconstructing a three-dimensional (3D) image based upon first and second two-dimensional (2D) images, the method comprising:

receiving a pair of composite images, the pair of composite images being generated from segmented images from the first and second 2D images, the segmented images comprising a first segmented image and a second segmented image respectively comprising even numbered lines and odd numbered lines of the first 2D image, the segmented images further comprising a third segmented image and a fourth segmented image respectively comprising even numbered lines and odd numbered lines of the second 2D image, wherein one of the first segmented image or the second segmented image forms a first half portion of a first composite image, wherein one of the third segmented image or the fourth segmented image forms a second half portion of the first composite image, wherein the other of the first segmented image or the second segmented image forms a first half portion of a second composite image, and wherein the other of the third segmented image or the fourth segmented image forms a second half portion of the second composite image; and

reconstructing the 3D image from the pair of composite images by de-interlacing the pair of composite images.

9. The method according to claim 8 wherein information from segmentation of the first 2D image is stored in the pair of composite images.

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

11. The method according to claim 8 wherein the first and second 2D images comprise first and second stereoscopic view images.

12. The method according to claim 8 wherein the segmented images are based upon a Top-and-Bottom (TaB) standard.

13. The method according to claim 8 wherein the segmented images are based upon Side-by-Side (SbS) standard.

14. The method according to claim 8 wherein the pair of composite images is based upon an 1080i standard.

15. An electronic device for reconstructing a three-dimensional (3D) image based upon first and second two-dimensional (2D) images, the electronic device comprising:

a de-interlacing circuit and a circuit cooperating therewith and being configured to

receive a pair of composite images, the pair of composite images being generated from segmented images from the first and second 2D images, wherein one of even numbered lines or odd numbered lines from the first 2D image form a first half block of a first composite image, wherein one of even numbered lines or odd numbered lines from the second 2D image form a second half block of the first composite image, wherein the other of even numbered lines or odd numbered lines from the first 2D image form a first half block of a second composite image, and wherein the other of even numbered lines or odd numbered lines from the second 2D image form a second half block of the second composite image; and
