Abstract

Reproduction device, including registration means arranged to optically register an image portion that is to be registered of an image. The reproduction device includes electronic signal processing means arranged to process a registered image portion, and includes and/or is connectable with reproduction means arranged to reproduce a processed registered image portion. The reproduction device is provided with localisation means arranged to determine a position of an indication body that is moveable with respect to the image and with respect to at least a part of the reproduction device. The reproduction device is arranged to relate a position of the image portion that is to be registered to the position of the indication body.

Claims

1. An electronic magnifier of text comprising:

a registration means arranged to optically register a desired portion of the text on paper;

an electronic signal processing means arranged to process at least the registered text portion of the desired portion of the text; and

a reproduction device arranged to reproduce and magnify the processed registered text portion;

wherein the reproduction device is provided with;

contactless localization means arranged to determine a position of an indication body that is moveable with respect to the text and with respect to at least a part of the reproduction device, and

in that the reproduction device is arranged to select a position of the text portion that is to be registered relative to the text in response to the determined position of the indication body, and provide a magnified desired portion of the text.

2. The electronic magnifier of text according to claim 1, wherein the localization means are arranged to use the registration means for determining the position of the indication body.

3. The electronic magnifier of text according to claim 1, wherein the localization means are arranged to use electromagnetic radiation, for determining the position of the indication body.

4. The electronic magnifier of text according to anyone of claims 1-3, wherein the localization means are arranged to use ultrasonic waves for determining the position of the indication body.

5. The electronic magnifier of text according to claim 3, wherein the electromagnetic radiation is infrared radiation.

6. The electronic magnifier of text according to claim 1, wherein the localization means are arranged to use detection of electromagnetic induction, induced by the indication body, for determining the position of the indication body.

7. The electronic magnifier of text according to claim 1, provided with electronic means arranged to relate the position of the text portion that is to be registered with the position of the indication body by using an automatic control.

8. The electronic magnifier of text according to claim 1, wherein the reproduction device is arranged to reproduce the processed registered text portion with a changed polarity with respect to the image portion that is to be registered.

9. The electronic magnifier of text according to claim 1, wherein the text portion that is to be registered includes readable text.

10. The electronic magnifier of text according to claim 9, wherein the reproduction device is arranged to reproduce the text acoustically.

11. The electronic magnifier of text according to claim 9, wherein the reproduction device is arranged to reproduce the text in a way so that the text has a better legibility for dyslectic persons.

12. The electronic magnifier of text according to claim 9, wherein the reproduction device is arranged to reproduce the text in braille.

13. The electronic magnifier of text according to claim 9, wherein the reproduction device is arranged to reproduce the text in a translated way.

14. The electronic magnifier of text according to claim 1, wherein the reproduction means are arranged to reproduce the text portion that is to be registered in colour.

15. The electronic magnifier of text according to claim 1, wherein the reproduction means include a display.

16. The electronic magnifier of text according to claim 15, wherein an inclination of the display with respect to the text is adjustable.

17. The electronic magnifier of text according to claim 1, wherein the reproduction means include a projector.

18. The electronic magnifier of text according to claim 1, wherein the reproduction means include a speaker.

19. The electronic magnifier of text according to claim 1, provided with first displacement means arranged for displacing at least part of the registration means with respect to the text and with respect to a part of the reproduction device in response to the registered position of the indication body.

20. The electronic magnifier of text according to claim 19, wherein the first displacement means include a motor.

21. The electronic magnifier of text according to claim 1, wherein the registration means are rigidly positioned in the reproduction device.

22. The electronic magnifier of text according to claim 21, wherein the registration means are arranged to optically register the text.

23. The electronic magnifier of text according to claim 1, wherein the signal processing means are arranged to select the text portion from the text in response to the determined position of the indication body.

24. The electronic magnifier of text according to claim 1, wherein the registration means include a camera.

25. The electronic magnifier of text according to claim 1, wherein the registration means are arranged to also register at least part of the indication body and to reproduce this at least partly together with the processed registered image portion.

26. The electronic magnifier of text according to claim 1, wherein the localization means include an engagement element arranged to engage with the indication body.

27. The electronic magnifier of text according to claim 1, provided with second displacement means arranged to displace the reproduction device in use with respect to the text.

28. The electronic magnifier of text according to claim 27, wherein the second displacement means include a rotatable roller.

29. The electronic magnifier of text according to claim 1, provided with a housing that at least partly surrounds the registration means, the reproduction means, and the electronic signal processing means.

30. The electronic magnifier of text according to claim 29, wherein the housing is provided with an entrance opening in which at least part of the indication body can be placed.

31. The electronic magnifier of text according to claim 1, provided with a support member for placing the text there against.

32. The electronic magnifier of text according to claim 1 and an indication body.

33. The electronic magnifier of text according to claim 32, wherein the indication body is at least partly transparent.

34. A method for electronically magnifying text comprising the steps of:

optically registering a desired portion of the text on paper with a registration means;

processing at least the registered text portion of the desired portion of the text with an electronic signal processing means; and

determining a position of an indication body that is moveable with respect to the text and with respect to at least a part of the reproduction device with a contactless localization means;

selecting a position of the registered text portion in response to the determined position of the indication body; and

reproducing and magnifying the processed selected registered text portion with a reproduction device.

35. The method according to claim 34, including registering a whole text, and wherein the selection of the position of the text portion is made by means of the processing of the registered whole text so as to obtain the text portion.
