Abstract

An image processing device includes a dividing unit for dividing objects of an input image, a metadata adding unit for adding metadata to each of the divided objects by performing OCR processing and morpheme analysis, a display unit for displaying at least one of the divided objects and the metadata added to the divided object, and a metadata accuracy determining unit for determining accuracies of the added metadata. The display unit preferentially displays metadata determined as being low in accuracy by the metadata accuracy determining unit.

Claims

1. An image processing device comprising:

a dividing unit for dividing objects of an input image;

a metadata adding unit for adding metadata to each of the divided objects by performing OCR processing and morpheme analysis;

a display unit for displaying at least one of the divided objects, and the metadata added to the divided object, and

a metadata accuracy determining unit for determining accuracies of the added metadata, wherein

the display unit preferentially displays metadata determined as being low in accuracy by the metadata accuracy determining unit.

2. The image processing device according to claim 1, wherein the metadata accuracy determining unit determines a word determined to be an unknown word through morpheme analysis as being metadata with low accuracy.

3. The image processing device according to claim 1, wherein the metadata accuracy determining unit determines a word which is determined to be a noun through morpheme analysis, and consists of one character, as being metadata with low accuracy.

4. The image processing device according to claim 1, wherein the display unit displays only metadata determined as being low in accuracy by the metadata accuracy determining unit.

5. The image processing device according to claim 1, wherein the display unit displays metadata determined as being low in accuracy by the metadata accuracy determining unit in an emphatic manner.

6. The image processing device according to claim 1, further comprising:

an object accuracy determining unit for determining a divided object as being low in accuracy when the divided object includes a large amount of metadata determined as being low in accuracy by the metadata accuracy determining unit, or when metadata determined as being low in accuracy by the metadata accuracy determining unit has been added to the divided object, wherein

the display unit preferentially displays the divided object determined as being low in accuracy by the object accuracy determining unit.

7. The image processing device according to claim 6, wherein the display unit displays a divided object determined as being low in accuracy by the object accuracy determining unit in an emphatic manner.

8. The image processing device according to claim 1, further comprising:

a recognizing unit for recognizing a source object having metadata which are characters extracted from the divided object and related objects around the source object, as a relevant group; and

a metadata correcting unit for correcting metadata determined as being low in accuracy by the metadata accuracy determining unit, wherein

the metadata correcting unit applies a correction that is the same as a correction of the metadata applied to other objects recognized as being in the same relevant group by the recognizing unit.

9. The image processing device according to claim 8, wherein metadata corrected by the metadata correcting unit are reflected in an OCR dictionary and a morpheme analysis dictionary.

10. An image processing method comprising:

dividing objects of an input image;

adding metadata to each of the divided objects by performing OCR processing and morpheme analysis;

displaying at least one of the divided objects and the metadata added to the divided object, and

determining accuracies of the added metadata, wherein

metadata determined as being low in accuracy is preferentially displayed.

11. The image processing method according to claim 10, wherein determining accuracies of the added metadata includes determining a word determined to be an unknown word through morpheme analysis as being metadata with low accuracy.

12. The image processing method according to claim 10, wherein determining accuracies of the added metadata includes determining a word determined to be a noun through morpheme analysis, and that consists of one character, as being metadata with low accuracy.

13. The image processing method according to claim 10, wherein only metadata determined as being low in accuracy is displayed.

14. The image processing method according to claim 10, wherein the metadata determined as being low in accuracy is displayed in an emphatic manner.

15. The image processing method according to claim 10, further comprising:

determining a divided object as being low in accuracy when the divided object includes a large amount of metadata determined as being low in accuracy, or when metadata determined as being low in accuracy has been added to the divided object, wherein

the divided object determined as being low in accuracy is preferentially displayed.

16. The image processing method according to claim 15, wherein the divided object determined as being low in accuracy is displayed in an emphatic manner.

17. The image processing method according to claim 10, further comprising:

recognizing a source object having metadata which are characters extracted from the divided object and related objects around the source object, as a relevant group; and

correcting metadata determined as being low in accuracy, wherein

a correction is applied that is the same as a correction of the metadata applied to other objects recognized as being in the same relevant group.

18. The image processing method according to claim 17, wherein corrected metadata are reflected in an OCR dictionary and a morpheme analysis dictionary.

19. A computer-readable storage medium storing computer-executable instructions for image processing, the computer-readable storage medium comprising:

computer-executable instructions for dividing objects of an input image;

computer-executable instructions for adding metadata to each of the divided objects by performing OCR processing and morpheme analysis;

computer-executable instructions for displaying at least one of the divided objects and metadata added to the divided object, and

computer-executable instructions for determining accuracies of the added metadata, wherein metadata determined as being low in accuracy is preferentially displayed.
