Abstract

The image is rendered on a conventional image writing surface such as a whiteboard or a portable writing pad device. The image is captured by a scanner or a CCD camera, and the digitized image data is analyzed for automatically generating separate image objects such as text areas, picture areas and so on. These image objects are now displayed for the user to edit information. For example, the user defines relational links between images and or image objects. Based upon the edited information, a document is generated for later retrieval and information dissemination.

Claims

1. A method of information processing, comprising the steps of:

inputting on an image drawing surface an image containing at least one image object, a predetermined set of image types being defined for the image objects;

automatically determining an area and a image type for each of the image objects;

displaying a display object for representing each of the image objects;

editing information on the image objects based upon the display object, the information including a directional link from one of the image objects as a link source to another of the image objects as a link destination; and

generating document data for the image according the edited information on the image objects, the image objects and the image type.

2. The method of information processing according to claim 1 wherein said inputting step further comprising the additional steps of:

drawing the image on a board with a marker; and

capturing the image in digital data.

3. The method of information processing according to claim 2 wherein said capturing step is continuous scanning of a portion of the image.

4. The method of information processing according to claim 2 wherein said capturing step is simultaneous digitizing of an entire portion of the image.

5. The method of information processing according to claim 2 wherein said automatically determining step further comprising:

removing noise in the image;

digitizing the image into digitized image data after the noise removal; and

quantizing the digitized image data.

6. The method of information processing according to claim 1 wherein the information includes a label for describing the image object.

7. The method of information processing according to claim 1 wherein the display object includes a label for describing the image object.

8. The method of information processing according to claim 1 wherein the information includes display information of the display objects.

9. The method of information processing according to claim 1 wherein the image objects contain other ones of the image objects.

10. The method of information processing according to claim 9 wherein the display objects are zoomed in and out.

11. The method of information processing according to claim 9 wherein the display objects are individually resized.

12. The method of information processing according to claim 1 wherein the link information specifies a relational link between the images.

13. The method of information processing according to claim 1 wherein the link information specifies a relational link between the image objects.

14. The method of information processing according to claim 1 wherein the information includes an image label.

15. The method of information processing according to claim 1 wherein the document data includes the HTML and the XML.

16. A system for information processing, comprising:

an image inputting unit having a conventional image drawing surface for drawing an image containing at least one image object, a predetermined set of image types being defined for the image objects;

a processing unit connected to said image inputting unit for automatically determining an area and a image type for each of the image objects and for displaying a display object for representing each of the image objects;

an editor connected to said processing unit for editing information on the image objects based upon the display object, the information including a directional link from one of the image objects as a source link to another of the image objects as a destination link; and

a document generating unit connected to said processing unit for generating document data for the image according the edited information on the image objects, the image objects and the image type.

17. The system for information processing according to claim 16 wherein said inputting unit further comprising an image capturing unit for capturing the image in digital data.

18. The system for information processing according to claim 17 wherein said image capturing unit is a scanner for continuously scanning of a portion of the image.

19. The system for information processing according to claim 17 wherein said image capturing unit is a CCD camera for simultaneous digitizing of an entire portion of the image.

20. The system for information processing according to claim 18 wherein said processing unit removes noise in the image, digitizes the image into digitized image data after the noise removal and quantizes the digitized image data.

21. The system for information processing according to claim 16 wherein the information includes a label for describing the image object.

22. The system for information processing according to claim 16 wherein the display object includes a label for describing the image object.

23. The system for information processing according to claim 16 wherein the information includes display information of the display objects.

24. The system for information processing according to claim 16 wherein the image objects contain other ones of the image objects.

25. The system for information processing according to claim 24 wherein said editor zooms the display objects in and out.

26. The system for information processing according to claim 24 wherein said editor individually resizes the display objects.

27. The system for information processing according to claim 16 wherein the link information specifies a relational link between the images.

28. The system for information processing according to claim 16 wherein the link information specifies a relational link between the image objects.

29. The system for information processing according to claim 16 wherein the information includes an image label.

30. The system for information processing according to claim 16 wherein said document generating unit generates the document data in the HTML.

31. The system for information processing according to claim 16 wherein said document generating unit generates the document data in the XML.

32. The system for information processing according to claim 16 further comprising a storage unit for storing the images, the image objects, the display objects and the information.

33. A method of retrofitting a conventional image inputting device for further image processing, comprising the steps of:

placing an image capturing device near the conventional image inputting device;

inputting on an image drawing surface of the conventional image inputting device an image containing at least one image object, a predetermined set of image types being defined for the image objects;

capturing the image in a predetermined digitized data format;

automatically determining an area and a image type for each of the image objects based upon the digitized data;

displaying a display object for representing each of the image objects;

editing information on the image objects based upon the display object, the information including a relational link between the image objects; and

generating document data for the image according the edited information on the image objects, the image objects and the image type.

34. The method of retrofitting a conventional image inputting device according to claim 33 further comprising an additional step of storing the generated document data.

35. The method of retrofitting a conventional image inputting device according to claim 33 wherein the relational link is directional from one of the image objects as a link source to another of the image objects as a link destination
