SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR CONTROLLING STEREO GLASSES SHUTTERS

Abstract

A system, method, and computer program product are provided for controlling stereo glasses shutters. In use, a right eye shutter of stereo glasses is controlled to switch between a closed orientation and an open orientation. Further, a left eye shutter of the stereo glasses is controlled to switch between the closed orientation and the open orientation. To this end, the right eye shutter and the left eye shutter of the stereo glasses may be controlled such that the right eye shutter and the left eye shutter simultaneously remain in the closed orientation for a predetermined amount of time.

Claims

1. A method, comprising: controlling a right eye shutter of stereo glasses to switch between a closed orientation and an open orientation; andcontrolling a left eye shutter of the stereo glasses to switch between the closed orientation and the open orientation;wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled such that the right eye shutter and the left eye shutter simultaneously remain in the closed orientation for a predetermined amount of time.

2. The method as recited in claim 1, wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled independently.

3. The method as recited in claim 2, wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled independently utilizing a first control signal for controlling the right eye shutter and a second control signal for controlling the left eye shutter.

4. The method as recited in claim 1, wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled utilizing a plurality of signals, one of which causes the right eye shutter and the left eye shutter to simultaneously transition to and remain in the closed orientation.

5. The method as recited in claim 1, wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled to permit stereo viewing of content on a display.

6. The method as recited in claim 5, wherein the display includes a liquid crystal display.

7. The method as recited in claim 1, wherein the right eye shutter of the stereo glasses is controlled such that the right eye shutter is in the open orientation at least for the duration of a first set of vertical blanking intervals, and the left eye shutter of the stereo glasses is controlled such that the left eye shutter is in the open orientation at least for the duration of a second set of vertical blanking intervals.

8. The method as recited in claim 7, wherein the right eye shutter of the stereo glasses is controlled such that the right eye shutter is in the open orientation for a period that exceeds the duration of the first set of vertical blanking intervals, and the left eye shutter of the stereo glasses is controlled such that the left eye shutter is in the open orientation for a period that exceeds the duration of the second set of vertical blanking intervals.

9. The method as recited in claim 7, wherein the right eye shutter of the stereo glasses is controlled such that the right eye shutter is in the open orientation only for the duration of the first set of vertical blanking intervals, and the left eye shutter of the stereo glasses is controlled such that the left eye shutter is in the open orientation only for the duration of the second set of vertical blanking intervals.

10. The method as recited in claim 7, wherein the first set of vertical blanking intervals alternate with the second set of vertical blanking intervals.

11. The method as recited in claim 7, wherein the first set of vertical blanking intervals and the second set of vertical blanking intervals occur between operations during which right eye content or left eye content is received from a content source.

12. The method as recited in claim 1, wherein a duration of the first set of vertical blanking intervals and the second set of vertical blanking intervals is increased.

13. The method as recited in claim 1, wherein the right eye shutter of the stereo glasses is controlled such that the right eye shutter is in the open orientation when only right eye content is being displayed, and the left eye shutter of the stereo glasses is controlled such that the left eye shutter is in the open orientation when only left eye content is being displayed.

14. The method as recited in claim 1, wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled such that the right eye shutter and the left eye shutter each remain in the open orientation for an adjustable time period.

15. The method as recited in claim 14, wherein the adjustable time period is adjusted to permit additional light through the right eye shutter and the left eye shutter.

16. The method as recited in claim 1, wherein the controlling is performed utilizing a controller connected to a computer system via a universal serial bus interface.

17. The method as recited in claim 1, wherein a backlight of the display is activated only when one of the shutters is in the open orientation.

18. A computer program product embodied on a computer readable medium, comprising:computer code for controlling a right eye shutter of stereo glasses to switch between a closed orientation and an open orientation; andcomputer code for controlling a left eye shutter of the stereo glasses to switch between the closed orientation and the open orientation;wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled such that the right eye shutter and the left eye shutter simultaneously remain in the closed orientation for a predetermined amount of time.

19. A system, comprising a graphics processor; anda controller in communication with the graphics processor, the controller for controlling a right eye shutter and a left eye shutter of stereo glasses to switch between a closed orientation and an open orientation;wherein the right eye shutter and the left eye shutter of the stereo glasses are controlled such that the right eye shutter and the left eye shutter simultaneously remain in the closed orientation for a predetermined amount of time.

20. The system as recited in claim 19, wherein the graphics processor is in communication with a display and a central processing unit via a bus.
