Abstract

Systems and methods for viewing stereoscopic television are described. The methods generate stereoscopic views from 3D content; synchronize with external view ware (e.g., shuttered glasses) to include shutter information and viewing geometry; sequence 3D content for multiple viewers at multiple perspective views; and output to a display component for viewing.

Claims

1. A television for viewing stereoscopic images, comprising:

an image engine configured to generate a plurality of stereoscopic scenes, each stereoscopic scene comprising a plurality of at least two pairs of stereoscopic conjugate images, wherein each of said at least two pairs of stereoscopic conjugate images represents a different perspective view of said each stereoscopic scene;

a display coupled to said image engine, the display configured to receive said plurality of stereoscopic scenes and display said plurality of stereoscopic scenes; and

a glasses interface configured to receive perspective view information from each of at least two viewing devices, the perspective view information including the distance from each of the at least two viewing devices to the display and the perspective view of each of the at least two viewing device relative to the display, and the image engine further configured to generate pair of stereoscopic conjugate images based on the perspective view information received from each of the at least two viewing devices;

a signal generator configured to transmit a perspective view selector that contains identification and synchronization information of said plurality of at least two pairs of stereoscopic conjugate images of each scene, the identification and synchronization information containing information for allowing the at least two viewing devices that receive the perspective view selector to be used to view a plurality of pairs of stereoscopic conjugate images on the display representing one perspective view of said each stereoscopic scene based on the position of each of the at least two viewing devices.

2. The television according to claim 1, wherein said image engine is further configured to generate a first perspective view as seen from a top of said each stereoscopic scene and a second perspective view as seen from a front of said each stereoscopic scene.

3. The television according to claim 1, wherein said image engine is further configured to generate a first perspective view as seen from a right side of said each stereoscopic scene and second perspective view as seen from a left side of said each stereoscopic scene.

4. The television according to claim 1, wherein said image engine is further configured to generate a first perspective view as seen from a bottom of said each stereoscopic scene and a second perspective view as seen from a front of said each stereoscopic scene.

5. The television according to claim 1, wherein the display comprises a liquid crystal display panel.

6. The television according to claim 1, wherein the display comprises a panel having organic light emitting diodes.

7. The television according to claim 1, wherein said image engine is configured to generate at least ten stereoscopic scenes per second.

8. A television system for viewing stereoscopic images, comprising:

an image engine configured to generate a plurality of stereoscopic scenes, each said scene comprising at least two pairs of stereoscopic conjugate images and each of said at least two pairs of stereoscopic conjugate images representing one of a plurality of different perspective views of said scene,

a display coupled to said image engine and configured to receive said plurality of stereoscopic scenes and to display said at least two pairs of stereoscopic conjugate images of each of said plurality of received scenes;

a signal generator configured to transmit a perspective view selecting signal that contains identification and synchronization information for said each pair of stereoscopic conjugate images; and

a first viewing device configured to receive said identification and synchronization information and to select only one perspective view of said pair of stereoscopic conjugate images for viewing, the viewing device configured to select one of said perspective views based on an angle between a plane of said display and a plane of said first viewing device.

9. The television system according to claim 8, wherein said image engine is further configured to generate a first perspective view as seen from a top of said each scene and a second perspective view as seen from a front of said each scene.

10. The television system according to claim 8, wherein said image engine is further configured to generate a first perspective view as seen from a right side of said each scene and a second perspective view as seen from a left side of said each scene.

11. The television system according to claim 8, wherein said image engine is further configured to generate a first perspective view as seen from a bottom of said each scene and a second perspective view as seen from a front of said each scene.

12. The television system according to claim 8, wherein said display comprises a liquid crystal display panel.

13. The television system according to claim 8, wherein said first viewing device comprises a shuttering mechanism, the shuttering mechanism configured to be synchronized with a pair of images corresponding to one of said plurality of perspective views.

14. The television system according to claim 13, wherein the first viewing device comprises a pair of glasses.

15. The television system of claim 8, wherein the selected perspective view is based on said identification and synchronization information.

16. The television system according to claim 8, wherein said image engine generates at least ten pairs of stereoscopic scenes per second.

17. A television system for viewing stereoscopic images, comprising:

an image engine configured to generate a plurality of stereoscopic scenes, each said scene comprising at least two pairs of stereoscopic conjugate images and each of said at least two pairs of stereoscopic conjugate images representing one of a plurality of different perspective views of said scene,

a display coupled to said image engine and configured to receive said plurality of stereoscopic scenes and to display said at least two pairs of stereoscopic conjugate images of each of said plurality of received scenes; and

a signal generator configured to transmit a perspective view selecting signal that contains identification and synchronization information for said each pair of stereoscopic conjugate images;

a first viewing device configured to receive said identification and synchronization information and to select only one perspective view of said pair of stereoscopic conjugate images for viewing; and

a second viewing device configured to receive said identification and synchronization information and to select only one perspective view of said pair of stereoscopic conjugate images for viewing, wherein the perspective view selected by the second viewing device is different than the perspective view selected by the first viewing device.

18. A viewing device, comprising:

a receiver configured to receive identification and synchronization information and to select to show a plurality of stereoscopic pairs of images corresponding to only one perspective view among at least two perspective views broadcast by a display system, wherein each said pair of images comprises a pair of stereoscopic conjugate images; and

a shuttering mechanism configured to be synchronized with said pair of images of said one perspective view,

wherein the viewing device selects one of said perspective views based on an angle between a plane of said display on which said plurality of pairs of images are displayed and a plane of said viewing device.
