Abstract

Apparatus for use in video conferencing, which apparatus comprises at least one video camera (50) for providing a video image signal of at least one person taking part in a video conference, at least one display means (46) on which the video image signal from a remote location is displayed, and at least one part-transmissive curved mirror (48) which enables the person to view the display means (46) with the video camera (50) being positioned on a side of the part-transmissive curved mirror (48) away from the person and at substantially eye level of the person, whereby persons using the apparatus for a video conference arc able to maintain eye contact with each other.

Claims

1-24. -24 (cancelled)

25. Apparatus for use in video conferencing, which apparatus comprises at least one video camera for providing a video image signal of at least one person taking part in a video conference, at least one display means on which the video image signal from a remote location is displayed, and at least one part-transmissive curved mirror which enables the person to view the display means with the video camera being positioned on a side of the part-transmissive curved mirror away from the person and at substantially eye level of the person, whereby persons using the apparatus for a video conference are able to maintain eye contact with each other.

26. Apparatus according to claim 25 in which the display means is a curved screen.

27. Apparatus according to claim 26 in which the curved screen is a curved projection screen, and in which the apparatus includes a projector for projecting the recording from the video camera as a display onto the curved projection screen.

28. Apparatus according to claim 27 in which the curved projection screen is a curved rear projection screen, and in which the projector projects the display onto a concave side of the rear projection screen.

29. Apparatus according to claim 28 in which the curved projection screen is a curved front projection screen, and in which the projector projects the display onto a convex side of the front projection screen.

30. Apparatus according to claim 27 and including at least one light path fold mirror, and in which the projector projects the display onto the curved projection screen via the fold mirror.

31. Apparatus according to claim 27 in which there are more than one of the projectors.

32. Apparatus according to claim 25 in which the display means is selected from the group consisting of an emissive display means, a cathode ray tube monitor, and a flat panel display means.

33. Apparatus according to claim 32 in which the display means is a flat panel display means, and in which the flat panel display means is selected from the group consisting of a liquid crystal flat panel display device, and an organic light emitting polymer display panel.

34. Apparatus according to claim 32 in which the flat panel display means is part of a lap top computer.

35. Apparatus according to claim 32 in which the flat panel display means is a plasma display panel.

36. Apparatus according to claim 25 in which the display means extends continuously in a horizontal direction such that the display means subtends a wider angle at the person.

37. Apparatus according to claim 25 in which the display means and the part-transmissive curve mirror are both extended continuously in a horizontal direction such that a wider-angle is subtended at the person.

38. Apparatus according to claim 25 in which the part-transmissive curved mirror is extended continuously in a horizontal direction such that the part-transmissive curved mirror subtends a wider angle at the person.

39. Apparatus according to claim 25 in which there are more than one of the display means, and in which the display means are arranged adjacent to each other and facing substantially away from the person.

40. Apparatus according to claim 25 in which two of the video cameras are positioned on the side of the part-transmissive curved mirror remote from the person, and in which the two video cameras are positioned with a horizontal separation such that a stereoscopic image signal of the person is made.

41. Apparatus according to claim 25 and including software for manipulating images such that the video image of the person is provided with desired orientation and distortion correction.

42. Apparatus according to claim 25 and including audio means for providing audio signals of the persons taking part in the video conference.

43. Apparatus according to claim 25 and including connection means whereby the visual displays are connected via a communications link providing means for transmitting audio and visual data between more than one of the display means, the communications link being provided by at least one local area network, a wide area network, multiple telephone lines, a high-speed data link, the Internet, a ISDN, or a wireless communications link.

44. Apparatus according to claim 25 in which the display means is a modular display means, whereby a plurality of the modular display means can be placed adjacent to each other in order to form an extended visual display.
