Abstract

Methods and apparatus for rendering plural channels on a common display are provided. In a method embodiment, a method for allowing sharing of a display by a plurality of users wishing to view a plurality of respective images includes displaying the plurality of respective images sequentially on the display. The method further includes selectively allowing the respective image to be viewed by the respective user, but not by any other of the plurality of users.

Claims

1. A display system, comprising:

a display device operable to simultaneously display in different polarizations, during successive time periods, sequentially alternating different ones of left or right eye stereoscopic perspective subchannel images of respective first and second image channels;

first and second eyewear devices, each comprising left and right lenses with respective filters for the different polarizations; and

a processor communicatively coupled to the eyewear devices and operable to control the eyewear devices to sequentially pass or block light through sequentially alternating different ones of the left and right lenses during the successive time periods in synchronization with the display device;

so that the first eyewear device will pass a left eye stereoscopic perspective subchannel image of the first image channel displayed by the display device when the second eyewear device will pass a right eve stereoscopic perspective subchannel image of the second image channel displayed by the display device, and the first eyewear device will pass a right eye stereoscopic perspective subchannel image of the first image channel displayed by the display device when the second eyewear device will pass a left eye stereoscopic perspective subchannel image of the second image channel displayed by the display device;

thereby enabling users of the first and second eyewear devices to simultaneously view different stereoscopic first and second channel images on the same display device.

2. The display system of claim 1, wherein the different stereoscopic first and second channel images on the same display device correspond to different images of a multi-player video game.

3. The display system of claim 1, further comprising a plurality of headsets each operable to provide sound corresponding to a particular one of the different stereoscopic first and second channel images on the same display device.

4. The display system of claim 1, further comprising a cradle, the cradle having a plurality of docking stations each operable to dock a respective one of the eyewear devices.

5. The display system of claim 4, wherein the cradle is further operable to charge the docked eyewear devices.

6. The display system of claim 4, wherein the cradle is coupled to the processor.

7. The display system of claim 1, further comprising a switch operable to control which of the different stereoscopic first and second channel images on a same display device a particular one of the plurality of users may view.

8. The display system of claim 1, wherein the display device is operable to simultaneously display in different polarizations, during the successive time periods, the sequentially alternating different ones of left or right eye stereoscopic perspective subchannel images of the respective first and second image channels;

and the first and second eyewear devices, each comprise left and right lenses with filters corresponding to the respective different polarizations.

9. A display system, comprising:

a processor operable to;

receive an image; and

display each of the received image and an optical negative of the image in a time period such that the received image is not perceptible to the human eye; and

one or more eyewear devices each operable to selectively filter the negative image such that the received image is perceptible to the human eye by allowing light to pass through the eyewear devices when the received image is displayed and not pass light when the optical negative of the image is displayed.

10. The display system of claim 9, wherein the received image is a stereoscopic image that is perceptible to the human eye as three-dimensional.

11. The display system of claim 9, wherein the processor is further operable to display each of the received image and an optical negative of the image in a time period such that the human eye perceives a substantially solid color.

12. The display system of claim 11, wherein the substantially solid color is a shade of grey.

13. A method for allowing sharing of a display by a plurality of users wishing to view a plurality of respective images, comprising:

displaying the plurality of respective images sequentially on the display; and

selectively allowing the respective image to be viewed by the respective user, but not by any other of the plurality of users

automatically generating an optical negative image of the respective image to be viewed by the respective user;

displaying the generated optical negative image; and

not allowing the displayed optical negative image to be viewed by the respective user.

14. A method for enabling simultaneous viewing of different stereoscopic first and second channel images on a common display device, comprising:

operating the display device to simultaneously display, during successive time periods, sequentially alternating different ones of left or right eye stereoscopic perspective subchannel images of respective first and second image channels;

providing first and second eyewear devices, each comprising left and right lenses; and

controlling the eyewear devices to sequentially pass or block light through sequentially alternating different ones of the left and right lenses during the successive time periods in synchronization with the operating of the display device;

so that the first eyewear device passes a left eye stereoscopic perspective subchannel image of the first image channel displayed by the display device when the second eyewear device passes a right eye stereoscopic perspective subchannel image of the second image channel displayed by the display device, and the first eyewear device passes a right eye stereoscopic perspective subchannel image of the first image channel displayed by the display device when the second eyewear device passes a left eye stereoscopic perspective subchannel image of the second image channel displayed by the display device.

15. The method of claim 14, wherein the first and second channel images correspond to respective first and second video streams of a multi-player video game.

16. The method of claim 14, wherein the display device is operated to simultaneously display in different polarizations, during the successive time periods, the sequentially alternating different ones of left or right eye stereoscopic perspective subchannel images of the respective first and second image channels;

and the first and second eyewear devices each comprise left and right lenses with filters corresponding to the respective different polarizations.
