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. Reproduction device, including registration means arranged to optically register an image portion that is to be registered of an image, including electronic signal processing means arranged to process at least a registered image portion, and including and/or being connectable with reproduction means arranged to reproduce a processed registered image portion, characterised in that the reproduction device is provided with, preferably contactless 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, and in that the reproduction device is arranged to select a position of the image portion that is to be registered relative to the image in response to the determined position of the indication body.

2. Reproduction device according to claim 1, wherein the localisation means are arranged to use the registration means for determining the position of the indication body.

3. Reproduction device according to claim 1, wherein the localisation means are arranged to use electromagnetic radiation, such as infrared radiation, for determining the position of the indication body.

5. Reproduction device according to anyone of claim 1, wherein the localisation means are arranged to use detection of electromagnetic induction, induced by the indication body, for determining the position of the indication body.

6. Reproduction device according to anyone of claim 1, provided with electronic means arranged to relate the position of the image portion that is to be registered with the position of the indication body by using an automatic control.

7. Reproduction device according to anyone of claims 1, wherein the reproduction means are arranged to reproduce the processed registered image portion magnified with respect to the image portion that is to be registered.

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

9. Reproduction device according to anyone of claim 1, wherein the image portion that is to be registered includes readable text.

10. Reproduction device according to claim 9, wherein the reproduction device is arranged to reproduce the text acoustically.

11. Reproduction device 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. Reproduction device according to anyone of claim 9, wherein the reproduction device is arranged to reproduce the text in braille.

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

14. Reproduction device according to anyone of claim 1, wherein the reproduction means are arranged to reproduce the image portion that is to be registered in colour.

15. Reproduction device according to anyone of claim 1, wherein the reproduction means include a display.

16. Reproduction device according to claim 15, wherein an inclination of the display with respect to the image is adjustable.

17. Reproduction device according to anyone of claim 1, 46, wherein the reproduction means include a projector.

18. Reproduction device according to anyone of claim 1, wherein the reproduction means include a speaker.

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

20. Reproduction device according to claim 19, wherein the first displacement means include a motor.

21. Reproduction device according to one of claim 1, wherein the registration means are rigidly positioned in the reproduction device.

22. Reproduction device according to claim 21, wherein the registration means are arranged to optically register the image.

23. Reproduction device according to one of claim 1, wherein the signal processing means are arranged to select the image portion from the image in response to the determined position of the indication body.

24. Reproduction device according to anyone of claim 1, wherein the registration means include a camera.

25. Reproduction device according to anyone of 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. Reproduction device according to anyone of claim 1, wherein the localisation means include an engagement element arranged to engage with the indication body.

27. Reproduction device according to anyone of claim 1, provided with second displacement means arranged to displace the reproduction device in use with respect to the image.

28. Reproduction device according to claim 27, wherein the second displacement means include a rotatable roller.

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

30. Reproduction device 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. Reproduction device according to anyone of claim 1, provided with a support member for placing the image thereagainst.

32. Assembly of an indication body and a reproduction device according to claim 1.

33. Assembly according to claim 32, wherein the indication body is at least partly transparent.

4. Reproduction device according to anyone of claim, wherein the localisation means are arranged to use ultrasonic waves for determining the position of the indication body.

34. Method for reproducing an image portion that is to be registered from an image by means of a reproduction device, the method including the following steps:

a) determining a position of an indication body;

b) selecting a position of the image portion that is to be registered relative to the image in response to the determined position of the indication body;

c) optically registering at least the image portion that is to be registered by means of registration means, optionally including registering the whole image;

d) electronically processing the registered whole image or the registered image portion;

and

e) reproducing a processed registered image portion.

35. Method according to claim 34, wherein step a) is carried out by using the registration means.

36. Method according to claim 34, wherein step c) includes registering the whole image, and wherein the selection of the position of the image portion in step b) is made by means of the processing of the registered whole image so as to obtain the image portion in step d).
