Abstract

An apparatus and system are provided for adjusting the depth of stereoscopic video content. The apparatus comprises a frame that supports a first lens and a second lens. The first lens is associated with a first image in a stereoscopic image pair and the second lens is associated with a second image in the stereoscopic image pair. An interface for controlling a parameter associated with the stereoscopic image pair is integrated into the frame of the apparatus. The system includes a display device configured to display stereoscopic video content and coupled to the apparatus for controlling the stereoscopic video content.

Claims

1. An apparatus comprising:

a first lens associated with a first image in a stereoscopic image pair;

a second lens associated with a second image in the stereoscopic image pair;

a frame that supports the first lens and the second lens; and

an interface integrated with the frame, wherein the interface enables a user to adjust a parameter associated with the stereoscopic image pair.

2. The apparatus of claim 1, wherein the parameter is a binocular disparity

3. The apparatus of claim 2, wherein the interface comprises a wheel.

4. The apparatus of claim 3, wherein the wheel is configured to increase the binocular disparity of the stereoscopic image pair when the wheel spins counterclockwise and decrease the binocular disparity when the wheel spins clockwise.

5. The apparatus of claim 2, wherein the interface comprises at least two buttons, and wherein a first button of the at least two buttons is configured to increase the binocular disparity of the stereoscopic image pair when the first button is depressed and a second button of the at least two buttons is configured to decrease the binocular disparity when the second button is depressed.

6. The apparatus of claim 1, wherein the apparatus comprises active stereoscopic glasses further including a power source.

7. The apparatus of claim 6, further comprising a first transceiver integrated with the frame and configured to receive a synchronization signal generated by a second transceiver associated with a display device and transmit a control signal corresponding to the interface to the second transceiver associated with the display device.

8. The apparatus of claim 6, wherein the apparatus further includes a button to enable/disable the display of stereoscopic video content on a display device.

9. The method of claim 1, the apparatus comprises passive stereoscopic glasses, and wherein the first lens comprises a polarized filter having a first orientation and the second lens comprises a polarized filter having a second orientation.

10. The method of claim 9, wherein the passive stereoscopic glasses further include:

a power source; and

a transmitter configured to transmit a control signal corresponding to the interface to a receiver associated with the display device.

11. A system, comprising:

a display device configured to display stereoscopic video content; and

a pair of stereoscopic glasses that include;

a first lens associated with a first image in a stereoscopic image pair,

a second lens associated with a second image in the stereoscopic image pair,

a frame that supports the first lens and the second lens, and

an interface integrated in the frame, wherein the interface enables a user to adjust a parameter associated with the stereoscopic image pair.

12. The system of claim 11, wherein the parameter is a binocular disparity.

13. The system of claim 12, wherein the interface comprises a wheel, and wherein the interface is configured to increase the binocular disparity of the stereoscopic image pair when the wheel spins counterclockwise and decrease the binocular disparity when the wheel spins clockwise.

14. The system of claim 11, further comprising a second pair of stereoscopic glasses, wherein the first pair of stereoscopic glasses is configured as a master and the second pair of stereoscopic glasses is configured as a slave.

15. The system of claim 14, wherein the interface implements a protocol that enables the second pair of stereoscopic glasses to be reconfigured as the master and the first pair of stereoscopic glasses to be configured as the slave.

16. The system of claim 11, further comprising;

a second display device configured to display stereoscopic video content; and

a second pair of stereoscopic glasses.

17. The system of claim 16, wherein the first pair of stereoscopic glasses is configured to control a first binocular disparity of the stereoscopic image pair displayed on the first display device and the second pair of stereoscopic glasses is configured to control a second binocular disparity of a second stereoscopic image pair displayed on the second display device.

18. The system of claim 11, further comprising a graphics processing unit, coupled to the display device and configured to generate the stereoscopic video content for display based on the parameter.

19. The system of claim 18, further comprising a host processor configured to execute a device driver, wherein the device driver receives a control signal from the interface to adjust the parameter.

20. The system of claim 18, further comprising an application configured to receive the control signal and generate an API call for a device driver for the graphics processing unit that adjusts the parameter.
