摘要:
A method for superimposing images on three-dimensional content, wherein a video stream is received which includes the three-dimensional content and a depth map for superimposing images on the three-dimensional content. Once the video stream has been received, images are superimposed on the three-dimensional content in a position in depth dependent on the superimposition depth map (DM). The superimposition depth map contains information about the depth of the three-dimensional content and is inserted as an image contained in a frame (C) of the video stream. The depth map has a smaller number of pixels than that of a two-dimensional image associated with the three-dimensional content. The invention also relates to devices enabling the implementation of the methods.

A method for generating a stereoscopic video stream (101) including composite images (C), the composite images (C) including information about a right image (R) and a left image (L), wherein pixels of the right image (R) and pixels of the left image (L) are selected, and the selected pixels are entered into a composite image (C) of the stereoscopic video stream. All the pixels of the right image (R) and all the pixels of the left image (L) are entered into different positions in the composite image (C), by leaving one of the two images unchanged and breaking up the other one into two regions (R1, R2) including a plurality of pixels and entering the regions into the composite image (C).

A method for generating a stereoscopic video stream includes composite images having pixels related to a right and a left image of a tridimensional video content; the pixels of the right and left images are inserted into a composite image of the stereoscopic video stream, all the pixels of the right and left images are inserted in the composite image by leaving one of said two images unaltered and breaking up the other one into regions including a plurality of pixels and entering the regions into the composite image; the composite image has larger dimensions than those necessary to allow the insertion of all pixels of the left and right images, and in the pixels of the composite image left after such insertion a depth map is inserted, whose elements correspond to the pixel depth of the tridimensional content.
摘要:
The present invention relates to a method for generating a stereoscopic video stream (101) comprising composite images (C) which comprise information about a right image (R) and a left image (L). According to the method, pixels are selected from the right image (R) and from the left image (L), and then the selected pixels are entered into a composite image (C) of the stereoscopic video stream. The method also provides for entering all the pixels of the right image (R) and all the pixels of the left image (L) into the composite image (C) by leaving one of said two images unchanged and breaking up the other one into regions (R1, R2, R3) comprising a plurality of pixels. Said regions are subsequently entered into the composite image (C). The invention also relates to a method for reconstructing the right and left images starting from a composite image, as well as to devices allowing said methods to be implemented.
