Abstract

A magnification system which allows viewing a magnified representation of an object is provided. The magnification system includes two main components: a handheld device and a base station. The handheld device is provided with a camera module, a processing unit and, optionally, a display unit. The base station has a frame structure and, optionally, a monitor. The frame structure includes a cradle for receiving the handheld device. The handheld device can function as a stand-alone device and can be carried around for use outside of the home or office or, generally, away from the base station, or it can be mounted on the base station where images of documents or other objects disposed on a workspace of the frame structure can be acquired by the camera module of the handheld device and shown on the monitor through the processing unit.

Claims

1. A magnification system comprising:

a handheld device comprising;

a camera module having a field of view and a working range, the camera module being adapted to acquire an image of an object within said field of view and working range; and

a processing unit for generating a magnified representation of the object based on the image thereof acquired by said camera module; and

a base station comprising a frame structure defining a workspace and comprising a cradle for removably receiving therein the handheld device, the cradle being positioned and configured so that the workspace is within the field of view and the working range of the camera module when the handheld device is received in the cradle.

2. The magnification system according to claim 1, wherein the base station further comprises a monitor mounted on the frame structure and adapted to display, via the processing unit of the handheld device, the magnified representation of the object.

3. The magnification system according to claim 1, wherein the handheld device comprises a display unit adapted to display the magnified representation of the object.

4. The magnification system according to claim 3, wherein the display unit is a touchscreen liquid crystal display.

5. The magnification system according to claim 1, wherein the handheld device is operable in a live magnification mode wherein the magnified representation is outputted in a real-time video stream.

6. The magnification system according to claim 1, wherein the handheld device is operable in an image capture mode wherein the magnified representation is outputted as a still view of the object.

7. The magnification system according to claim, 1 wherein the handheld device is operable in a text overlay mode whereby textual information contained in the image of the object acquired by the camera module is recognized and converted to machine-encoded text by a text recognition module of the processing unit, and wherein the magnified representation is outputted as a still view of the object on which is overlaid the machine-encoded text.

8. The magnification system of claim 7, wherein the handheld device is operable in a text-to-speech mode, the processing unit further comprises a text-to-speech module for converting the machine-encoded text rendered by the text recognition module to a speech output, and at least one of the handheld device and the base station comprises a speaker device for outputting the speech output.

9. The magnification system of claim 1, wherein the processing unit comprises a memory element for storing the magnified representation of the object.

10. The magnification system according to claim 1, wherein the frame structure comprises a user interface adjacent the workspace, the user interface being in communication with the processing unit when the handheld device is received in the cradle to allow a user to act on the magnified representation of the object.

11. The magnification system according to claim 10, wherein the user interface of the frame structure comprises a touchpad.

12. The magnification system according to claim 11, wherein the touchpad is responsive to a pan gesture, to a swipe gesture, to a tap gesture, and to a pinch-and-zoom gesture.

13. The magnification system according to claim 11, wherein the user interface of the frame structure further comprises at least one control button.

14. The magnification system according to claim 1, wherein the frame structure comprises a lighting assembly for illuminating the workspace.

15. The magnification system according to claim 1, wherein the cradle is disposed above the workspace.

16. The magnification system according to claim 1, wherein the handheld device comprises a user interface in communication with the processing unit to allow a user to act on the magnified representation of the object.

17. The magnification system according to claim 16, wherein the user interface of the handheld device comprises a touchscreen.

18. The magnification system according to claim 17, wherein the touchscreen is responsive to a pan gesture, to a swipe gesture, to a tap gesture, and to a pinch-and-zoom gesture.

19. The magnification system according to claim 17, wherein the user interface of the handheld device further comprises at least one control button.

20. The magnification system according to claim 1, wherein the handheld device further comprises a lighting assembly configured to project light within the field of view thereof for illuminating the object.

21. The magnification system according to claim 5, wherein the processing unit is adapted to output the real-time video stream at a frame rate of at least 30 frames per second.

22. The magnification system according to claim 1, wherein the magnified representation of the object is obtained from an optical magnification performed by the camera module.

23. The magnification system according to claim 1, wherein the magnified representation of the object is obtained from a digital magnification performed by at least one of the camera module and the processing unit.

24. The magnification system according to claim 2, wherein the magnified representation of the object is obtained from a native magnification achieved via the monitor of the base station.

25. The magnification system according to claim 3, wherein the magnified representation of the object is obtained from a native magnification achieved via the display unit of the handheld device.
