Abstract

A handheld viewing device (1) comprises an electronic camera (2) housed in a camera part (7) for capturing a visual image of text on a page, and an electronic monitor (3) housed in a monitor part (4) for displaying the visual image of the text. The camera part (7) is pivotably movable relative to the monitor part (4) from a stowed configuration to a reading configuration, and further to a writing configuration. In the stowed configuration, the plane of the camera part (7) is substantially co-planar with the plane of the monitor part (4), and thus the device (1) presents a very low-profile compact size and shape. In the reading configuration, the camera (2) points in the direction of the page, and the camera part (7) is spaced above the page to ensure that there is sufficient distance between the camera (2) and the page to enable the camera (2) to capture the visual image of the text. In the writing configuration, the camera (2) is still pointed in the direction of the page but slightly outwards to enable a user to place the tip of a pen within the view of the camera (2).

Claims

1. A handheld viewing device comprising:

a capture element for capturing a visual image of at least part of a surface; and

a display element for displaying a visual image;

the capture element being movable relative to the display element between a stowed configuration and at least one capturing configuration.

2. A device as claimed in claim 1 wherein the display element comprises:

a base side for placement against the surface; and

a display side for displaying the visual image;

in the at least one capturing configuration, the capture element being located further from the base side than in the stowed configuration.

3. A device as claimed in claim 2 wherein in the stowed configuration, a first side of the capture element lies substantially in the plane of the base side.

4. A device as claimed in claim 2 wherein in the stowed configuration, a second side of the capture element lies substantially in the plane of the display side.

5. A device as claimed in claim 2 wherein the display side is provided on the opposite side of the display element to the base side.

6. A device as claimed in claim 1 wherein the display element is substantially planar.

7. A device as claimed in claim 1 wherein the capture element is substantially planar.

8. A device as claimed in claim 1 wherein in the stowed configuration, the plane of the capture element is substantially co-planar with the plane of the display element.

9. A device as claimed in claim 1 wherein in the at least one capturing configuration, the plane of the capture element is substantially out-of-plane with respect to the plane of the display element.

10. A device as claimed in claim 1 wherein the capture element is movable relative to the display element between the stowed configuration and a reading capturing configuration, and between the stowed configuration and a writing capturing configuration.

11. A device as claimed in claim 1 wherein the capture element is pivotably movable relative to the display element.

12. A device as claimed in claim 11 wherein the pivot axis is substantially parallel to the plane of the display element.

13. A device as claimed in claim 11 wherein the pivot axis is located closer to the display side than to the base side.

14. A device as claimed in claim 11 wherein the capture element is pivotable relative to the display element through an angle of approximately 90 degrees from the stowed configuration to the reading configuration.

15. A device as claimed in claim 11 wherein the capture element is pivotable relative to the display element through an angle of greater than 90 degrees from the stowed configuration to the writing configuration.

16. A device as claimed in claim 15 wherein the capture element is pivotable relative to the display element through an angle of approximately 135 degrees from the stowed configuration to the writing configuration.

17. A device as claimed in claim 1 wherein the device comprises an activate/deactivate element for activating and/or deactivating the capture element and/or the display element.

18. A device as claimed in claim 17 wherein the activate/deactivate element comprises a user interface control.

19. A device as claimed in claim 17 wherein the activate/deactivate element comprises at least one switch.

20. A device as claimed in claim 17 wherein the activate/deactivate element is configured to be triggered responsive to the capture element being moved relative to the display element between the stowed configuration and the at least one capturing configuration.

21. A device as claimed in claim 20 wherein the capture element comprises at least one protrusion for engaging the switch to trigger the switch upon movement relative to the display element.

22. A device as claimed in claim 21 wherein the protrusion comprises a cam-shaped arm.

23. A device as claimed in claim 1 wherein the capture element is detachably mounted to the display element.

24. A device as claimed in claim 1 wherein the device comprises a communications system to facilitate communication between the capture element and the display element.

25. A device as claimed in claim 24 wherein the communications system is configured to facilitate wireless communication between the capture element and the display element.

26. A device as claimed in claim 24 wherein the communications system comprises a connecting lead.

27. A device as claimed in claim 1 wherein the display element is configured to display the captured visual image.

28. A device as claimed in claim 1 wherein the display element is configured to display a visual image derived from the captured visual image.

29. A device as claimed in claim 28 wherein the device comprises a processor configured to magnify the captured visual image before display.

30. A device as claimed in claim 28 wherein the device comprises a processor configured to alter the captured visual image before display.

31. A device as claimed in claim 1 wherein the capture element comprises a camera.

32. A device as claimed in claim 31 wherein the camera comprises an electronic camera.

33. A device as claimed in claim 1 wherein the display element comprises an electronic monitor.

34. A device as claimed in claim 33 wherein the display element comprises a housing, the monitor being movable relative to the housing between a stowed configuration and a viewing configuration.

35. A device as claimed in claim 34 wherein the monitor is pivotably movable relative to the housing.

36. A device as claimed in claim 1 wherein the device is portable.

37. A device as claimed in claim 36 wherein the device is configured to be carried in a pocket.

38. A device as claimed in claim 37 wherein the device is sized to be carried in a pocket.
