Abstract

A system and method for presenting and capturing images on a presentation board are described. More particularly, embodiments of the present invention provide a projector adapted to display one or more images onto a surface and a camera adapted to capture the one or more images from the surface. Also provided is an interface electronics coupled to the projector and to the camera. The interface electronics is adapted to feed the projector with the one or more images and adapted to process the one or more images from the camera. Also a user can control the presentation system by modifying the one or more images on the surface.

Claims

1. An image capture and display (ICD) device comprising:

a projector adapted to display at least one image onto a surface;

a camera adapted to capture the one or more images from the surface; and

interface and control electronics coupled to the projector and to the camera, wherein the interface electronics is adapted to provide the projector with the one or more images and adapted to process the one or more images from the camera.

2. The ICD device of claim 1 wherein the interface and control electronics is controlled by a computer system.

3. The ICD device of claim 1 wherein the interface and control electronics comprises a processor.

4. The ICD device of claim 1 wherein the interface and control electronics can modify the at least one image.

5. The ICD device of claim 1 wherein an input device can be utilized with the ICD device to provide markings on the surface.

6. The ICD device of claim 5 wherein the input device comprises a laser pointer.

7. The ICD device of claim 5 wherein the input device comprises one of a keyboard, mouse, touch screen, pad, and stylus device.

8. The ICD device of claim 5 wherein the input device provides a modification to an image on the surface.

9. The ICD device of claim 1 wherein the camera comprises a digital camera.

10. The ICD device of claim 1 wherein the camera comprises a CCD camera.

11. The ICD device of claim 1 wherein a dual-optic system is provided wherein separate optical paths are provided for images that are projected by the projector and for images that are captured by the camera.

12. The ICD device of claim 1 which further comprises a memory coupled to the interface electronics upon which image data can be stored and from which presentations may be retrieved.

13. The ICD device of claim 1 further including a computer system coupled to the ICD device.

14. The ICD device of claim 1 wherein at least one image originates from data stored on the computer system.

15. A method for capturing and displaying images on a presentation board, the method comprising the steps of:

(a) displaying at least one image onto a surface of the presentation board utilizing a projector;

(b) capturing the at least one image from the surface utilizing a camera;

(c) providing the at least one image on the surface utilizing interface and control electronics, the interface electronics being coupled to the camera and the projector; and

(d) processing the at least one image by the interface and control electronics.

16. The method of claim 15 wherein the at least one image can be modified by utilizing the interface and control electronics.

17. The method of claim 15 wherein the processing step of (d) further comprises the step of (d2) automatically initiating software that takes into account projected messages when comparing viewed images, looking for a change.

18. The method of claim 15 further comprising the step of (e) determining a registration of displayed pixels and viewed pixels.

19. The method of claim 15 further comprising the step of (d) mapping between projected pixels and viewed pixels

20. The method of claim 15 further comprising the step of (e) compensating for surface and lighting defects.

21. The method of claim 15 wherein the interface and control electronics is controlled by a computer system.

22. The method of claim 15 wherein the interface and control electronics comprises a processor.

23. The method of claim 15 wherein the interface and control electronics can modify the at least one image.

24. The method of claim 15 wherein an input device can be utilized with the ICD device to provide markings on the surface.

25. The method of claim 24 wherein the input device comprises a laser pointer.

26. The method of claim 24 wherein the input device comprises one of a keyboard, mouse, touch screen, pad, and stylus device.

27. The method of claim 24 wherein the input device provides a modification to an image on the surface.

28. An image capture and display (ICD) system comprising:

a presentation board;

an ICD device adapted to display at least one image onto the presentation board; and

a computer system for communicating with the ICD device to provide the at least one image on the presentation board.

29. The ICD system of claim 28 wherein the ICD device further comprises:

a projector adapted to display at least one image onto a surface;

a camera adapted to capture the one or more images from the surface; and

interface and control electronics coupled to the projector and to the camera, wherein the interface electronics is adapted to provide the projector with the one or more images and adapted to process the one or more images from the camera.

30. The ICD system of claim 29 wherein the interface and control electronics comprises a processor.

31. The ICD system of claim 29 wherein the interface and control electronics can modify the at least one image.

32. The ICD system of claim 29 wherein an input device can be utilized with the ICD device to provide markings on the surface.

33. The ICD system of claim 32 wherein the input device comprises a laser pointer.

34. The ICD system of claim 32 wherein the input device comprises one of a keyboard, mouse, touch screen, pad, and stylus device.

35. The ICD system of claim 32 wherein the input device provides a modification to an image on the surface.

36. The ICD system of claim 29 wherein the camera comprises a digital camera.

37. The ICD system of claim 29 wherein the camera comprises a CCD camera.

38. The ICD system of claim 29 wherein a dual-optic system is provided wherein separate optical paths are provided for images that are projected by the projector and for images that are captured by the camera.

39. The ICD system of claim 29 which further comprises a memory coupled to the interface electronics upon which image data can be stored and from which presentations may be retrieved.
