Abstract

A visual communication system that is suitable for use in connection with a display surface is disclosed. The system includes a camera or other data-capturing device that can be remotely positioned from the display surface. A control unit receives image data from the camera or data-capturing device and processes the image data to create an electronic image of the display surface.

Claims

1-51. -51. (canceled)

52. A visual communication system for acquiring an image associated with a display surface, the system comprising:

a data-capturing device that includes an operable drive unit and a sled moved under control of the drive unit, the sled including an optical-to-electronic imager; and

a control unit in communication with the data-capturing device, the control unit configured to receive image data from the optical-to-electronic imager and process the image data to create an electronic image of the display surface.

53. The system of claim 52, wherein movement of the sled is guided by at least one guide member.

54. The system of claim 52, wherein the sled is capable of moving in a reciprocating manner to scan at least a portion of the display surface.

55. The system of claim 52, wherein the optical-to-electronic imager includes a charged coupling device.

56. The system of claim 52, wherein the data capturing device includes a stabilization mechanism.

57. The system of claim 56, wherein the stabilization mechanism includes a pin and slot arrangement.

58. The system of claim 52, further including a drive mechanism functionally linking the drive unit to the moveable sled.

59. The system of claim 58, wherein the drive mechanism includes a rack and pinion, a screw type, or a worm drive arrangement.

60. The system of claim 52, further comprising an arrangement of optically interactive lens components organized in the form of an optical stack.

62. The system of claim 60, wherein the optical stack exhibits a focal length of approximately 4.5.

63. The system of claim 60, wherein at least one of the lens components includes infrared filtering capability.

64. The system of claim 60, including an infrared filter that is external to the camera.

65. A system for obtaining information from a display surface, the system comprising:

a camera;

a selectively operable drive unit;

an arrangement of optically interactive lens components organized in the form of an optical stack; and

a sled moved under control by the drive unit, the moveable sled including an optical-to-electronic imager.

66. The system of claim 65, further comprising a control unit in communication with the camera, the control unit configured to receive image data from the optical-to-electronic imager and process image data to create an electronic image of the display surface.

67. The system of claim 65, wherein movement of the sled is guided by at least one guide member.

68. The system of claim 65, wherein the sled is capable of moving in a reciprocating manner to scan at least a portion of the display surface.

69. The system of claim 65, wherein the optical-to-electronic imager includes a charged coupling device.

70. The system of claim 65, further comprising a drive mechanism functionally linking the drive unit to the moveable sled.

71. The system of claim 65, wherein the optical stack exhibits a focal length of approximately 4.5.

72. The system of claim 65, wherein at least one of the lens components includes infrared filtering capability.
