Abstract

An image reading apparatus to correct an error in a correction mode desired by a user so as to satisfy a user'"'"'s desire includes a control unit to correct an error generated in a scanned image of a bound document due to a shape of the bound document, and a display unit to display the image of the document of which the error is corrected. The control unit corrects the error in a correction mode input by the user.

Claims

1. An image reading apparatus, comprising:

a control unit to correct an error generated in a scanned image of a bound document due to a shape of the bound document; and

a display unit to display the image of the document of which the error is corrected,

wherein the control unit corrects the error in a correction mode input by a user.

4. The image reading apparatus according to claim 1, wherein the control unit includes:

an analysis unit to analyze the image of the document and detect the error generated due to a shape of the bound document; and

a correction unit to correct the detected error in a predetermined correction mode.

5. The image reading apparatus according to claim 4, wherein the analysis unit includes a size detector to detect a size area of the scanned image of the document.

6. The image reading apparatus according to claim 4, wherein the analysis unit includes a page detector to detect page areas of the image of the document.

7. The image reading apparatus according to claim 4, wherein the analysis unit includes a boundary detector to detect a boundary area of the image of the document.

8. The image reading apparatus according to claim 4, wherein the analysis unit includes a central portion detector to detect a central portion of the image of the document.

9. The image reading apparatus according to claim 4, wherein the analysis unit includes a shadow detector to detect a shadow area of a central portion of the image of the document.

10. The image reading apparatus according to claim 1, further comprising:

a memory to store the scanned image of the document.

11. The image reading apparatus according to claim 1, wherein the display unit further displays a selection message to select the correction mode.

12. The image reading apparatus according to claim 11, further comprising:

an input unit to allow the user to input the correction mode.

13. The image reading apparatus according to claim 11, wherein the display unit further outputs a change message relating to whether the correction mode is changed.

14. The image reading apparatus according to claim 12, wherein the input unit allows the user to input change selection information.

15. The image reading apparatus according to 1, wherein the correction mode includes an output correction mode to divide the document into pages and output the pages of the document, a straight-line correction mode to correct a curved portion of a central portion of the document to an original state, a removal correction mode to remove a shadow area of the central portion of the document, and a cut correction mode to cut the image of the document.

2. An image reading apparatus, comprising:

an input unit to allow a user to input a correction mode in order to correct an error generated in a scanned image of a bound document due to a shape of the bound document; and

a control unit to correct the error in the input correction mode.

3. The image reading apparatus according to claim 2, further comprising:

a display unit to display the scanned image of the document.

16. A method of correcting an image using an image reading apparatus, the method comprising:

scanning a bound document;

correcting an error generated in an image of the document due to a shape of the bound document;

displaying the image of the document on a predetermined screen display device;

allowing a user to input a correction mode; and

correcting the error in the input correction mode.

17. The method according to claim 16, further comprising:

analyzing the image of the document and detecting the error generated due to the shape of the bound document, after the bound document is scanned; and

correcting the detected error in a predetermined correction mode.

18. The method according to claim 17, wherein, in order to detect the error, a size area of the scanned image of the document is detected;

page areas of the image of the document are detected;

a boundary area of the image of the document is detected;

a central portion of the image of the document is detected; and

a shadow area of the central portion of the image of the document is detected.

19. The method according to claim 16, wherein the scanned image of the document is stored after the bound document is scanned.

20. The method according to claim 16, wherein, when the image of the document is displayed, a change message relating to whether the correction mode is changed is further displayed.

21. The method according to claim 20, wherein a selection message to select the correction mode is displayed together with the change message.

22. The method according to claim 20, wherein the user is allowed to input change selection information.

23. An image reading apparatus, comprising:

a control unit to control error correction in a scanned image of a document,

wherein the error correction corresponds to detecting and dividing the document into a plurality of page areas on a basis of a central portion thereof.

24. The apparatus of claim 23, wherein the error is corrected in a correction mode by a user input.

25. An image reading apparatus, comprising:

a control unit to control an correction of an error generated in a scanned image of a document by detecting and dividing the document into a plurality of page areas on a basis of a central portion thereof; and

a displaying unit to display and to allow a user to select change selection information corresponding to the error correction of the control unit.

26. A method of correcting an image using an image reading apparatus, the method comprising:

controlling error correction in a scanned image of a document by detecting and dividing the document into a plurality of page areas on a basis of a central portion thereof; and

displaying change selection information corresponding to the error correction of the control unit.

27. The method of claim 26, further comprising:

allowing a user to select the change selection information; and

correcting the error based on the selection by the user.

28. A computer-readable recording medium having embodied thereon a computer program to execute a method, wherein the method comprises:

controlling error correction in a scanned image of a document by detecting and dividing the document into a plurality of page areas on a basis of a central portion thereof; and

displaying change selection information corresponding to the error correction of the control unit.
