Abstract

The apparatus and method for maintaining eye contact during person to person video telecommunication includes disposing a video camera directly behind an OLED video display screen and synchronizing the video camera with the illumination levels of the display screen. This configuration allows the camera to observe the user from a natural face-on perspective, and effectively reconnects the eye-lines of the users, and restores all natural face-to-face emotional cues ordinarily disrupted by eye-line dissociation. Some embodiments include the use of this technique for stand-alone monitors, handheld devices, laptop computers, and the potential use in conjunction with autostereoscopic display technology, including wide look around or head and eye-tracking, for 3 dimensional eye-to-eye telecommunication.

Claims

1. An apparatus for maintaining eye contact during person to person video telecommunication, the apparatus comprising:

a display device for conducting person to person video telecommunications, said display device having a display matrix; and

at least one video camera disposed behind said display matrix, said video camera having capture frame rate equivalent to a frame rate of the display device.

2. The apparatus according to claim 1, wherein said display device comprises an organic light emitting diode (OLED) display.

3. The apparatus according to claim 1, wherein said display device further comprises substrate layer disposed between the display matrix and said video camera, said substrate layer preventing light from said display matrix from being exposed to said video camera.

4. The apparatus according to claim 1, wherein said display device further comprises a microphone for use in conjunction with said video camera.

5. The apparatus according to claim 1, wherein said video camera comprises a syncable shutter speed of greater than 1/60th of a second.

6. The apparatus according to claim 1, wherein said video camera and said display device are housed in the same display device housing.

7. The apparatus according to claim 1, wherein said video camera and said display device are contained within a portable device.

8. The apparatus according to claim 7, wherein the portable device is one selected from a group consisting of a personal digital assistant (PDA), a cellular telephone, a two way pager and a laptop computer.

9. The apparatus according to claim 1, further comprising a plurality of video cameras disposed behind the display device.

10. An apparatus for maintaining eye contact during person to person video telecommunication, the apparatus comprising:

a display device for providing a display of a display image source and being capable of being used to conduct person to person video telecommunications, said display image source having a frame rate and phase characteristics; and

a video camera disposed behind said display matrix and having a shutter, said frame rate and phase characteristics of the display image source being used to drive said camera shutter.

11. The apparatus according to claim 10, wherein said wherein said frame rate and said phase characteristics are offset in time.

12. The apparatus according to claim 11, wherein said offset in time sets the phase characteristic such that said camera shutter exposes in time when said display device is at a minimum illumination level.

13. The apparatus according to claim 10, wherein said camera comprises a capture frame rate, said capture frame rate being equivalent to a frame rate of said display device.

14. A method for maintaining eye contact during person to person video telecommunication, the method comprising:

providing a display device;

providing at least one video camera positioned behind the display device; and

synchronizing the at least one video camera with the frame refresh rate and phase characteristics of a display image source.

15. The method according to claim 14, wherein said display device is an organic light emitting diode (OLED) display device.

16. The method according to claim 14, further comprising driving the at least one video camera using frame rate and phase characteristics of a display image source.

17. The method according to claim 16, wherein said the phase of the display image source is set so as enable the at least one video camera to acquire images when said display device is at a minimum level of illumination.

18. The method according to claim 14, further comprising synchronizing a shutter speed of the at least one video camera with a frame rate of the display device.

19. The method according to claim 18, wherein the at least one video camera has a shutter speed faster than the frame rate of the display device.
