Establishing 3d video conference presentation on 2d display

Abstract

A 3D video conferencing system includes two cameras at each of two video conferencing locations. Images from the two cameras are exchanged between the locations and are combined at the receiving location in accordance with the angle at which the viewer at the receiving location is viewing an otherwise 2D display to give the illusion of depth perception.

         20 . A 3D video conferencing system, comprising:
 first and second cameras configured for use at a first video conferencing location which is configured for communicating with third and fourth cameras at a second video conferencing location;   a transmitter configured for sending, under control of a processor, images from the first and second cameras to the second video conferencing location for combination of the images at the second video conferencing location in accordance with an angle at which a viewer at the second video conferencing location is viewing an otherwise 2D display at the second video conferencing location to give the illusion of depth perception; and   a receiver configured for receiving images from the third and fourth cameras such that the images from the third and fourth cameras can be combined by a processor configured for communicating with the receiver at the first video conferencing location in accordance with an angle at which a viewer at the first video conferencing location is viewing a display at the first video conferencing location.   
     
     
         21 . The system of  claim 20 , wherein the two images from the respective two cameras of the second video conferencing location are offset from each other, then combined, and presented on the display at the first video conferencing location according to the angle at which the viewer at the first video conferencing location is viewing the display at the first video conferencing location. 
     
     
         22 . The system of  claim 20 , wherein the two images from the respective two cameras of the second video conferencing location are offset from each other, then combined, and presented on the display at the first video conferencing location according to a trigonometric function of the angle at which the viewer at the first video conferencing location is viewing the display at the first video conferencing location. 
     
     
         23 . The system of  claim 20 , wherein the display at the first video conferencing location includes a TV. 
     
     
         24 . A 3D video conferencing system, comprising:
 two cameras configured for use at a first video conferencing location;   at least one processor configured for use at the first video conferencing location;   at least one computer readable storage medium configured for use at the first video conferencing location and bearing instructions which when executed by the processor configure the processor to execute logic comprising:   receiving images from at least two cameras at a second video conferencing location communicating with the first video conferencing location;   sending images from the two cameras of the first video conferencing location to the second video conferencing location for combination at the second video conferencing location in accordance with the angle at which a viewer at the second video conferencing location is viewing an otherwise 2D display at the second video conferencing location to give the illusion of depth perception; and   combining the images from the two cameras of the second video conferencing location in accordance with the angle at which a viewer at the first video conferencing location is viewing a display at the first video conferencing location.   
     
     
         25 . The system of  claim 24 , wherein the processor when executing the instructions is configured to combine two images from the respective two cameras of the second video conferencing location, the two images from the respective two cameras of the second video conferencing location being offset from each other, the processor when executing the instructions being configured to present a combination of the two images from the respective two cameras of the second video conferencing location on the display at the first video conferencing location according to the angle at which the viewer at the first video conferencing location is viewing the display at the first video conferencing location. 
     
     
         26 . The system of  claim 24 , wherein the processor when executing the instructions is configured to combine the two images from the respective two cameras of the second video conferencing location which are offset from each other, the processor when executing the instructions being configured to present a combination of the two images from the respective two cameras of the second video conferencing location on the display at the first video conferencing location according to a trigonometric function of the angle at which the viewer at the first video conferencing location is viewing the display at the first video conferencing location. 
     
     
         27 . The system of  claim 24 , wherein the display at the first video conferencing location includes a TV.
