Digitizing apparatus for generating portable data file by compiling image data of pages into single file, having page number conversion unit for converting page numbers into electronic document page numbers

摘要

A page numbering unit assigns an electronic document page number to each of image data of a plurality of pages stored in a storage unit. An image analysis unit extracts a page number described in each of the image data of the plurality of pages stored in the storage unit. The image analysis unit identifies image data that describes page numbers for searching for other pages, from among the image data of the plurality of pages stored in the storage unit. A page number comparator compares the assigned electronic document page number with the extracted page number, for each of the image data of the plurality of pages. A page number conversion unit converts the page numbers for searching into the corresponding electronic document page numbers, based on a result of comparison by the page number comparator.

主权项

1. A digitizing apparatus that generates an electronic document file by compiling image data of a plurality of pages including a cover page, table-of-content page and ordinary page into a single file, the apparatus comprising:
a page numbering unit that assigns an electronic document page number to each of the image data of the plurality of pages; a page number extraction unit that classifies the image data of the plurality of pages into any of the cover page, table-of-content page and ordinary page and extracts a page number described in each of the image data of the plurality of pages; a page number comparator that compares the electronic document page number assigned by the page numbering unit with the page number extracted by the page number extraction unit, for each of the image data of the plurality of pages; a search page identification unit that identifies image data of the table-of-content page representative of searching page numbers to search for other pages, from among the image data of the plurality of pages; and a page number conversion unit configured to perform ordinary page conversion processing and table-of-content page conversion processing, wherein in a case of the ordinary page conversion processing, the page number conversion unit is configured to delete the page number at a page number description area of image data of the ordinary page when the electronic document page number assigned by the page numbering unit differs from the page number extracted by the page number extraction unit, and to generate a numeric font of the electronic document page number corresponding to the page number according to a result of comparison performed by the page number comparator, such that the page number at the page number description area is converted into the corresponding electronic document page number by adding the generated numeric font to the page number description area where the page number has been deleted, and wherein in a case of the table-of-content page conversion processing, the page number conversion unit is configured to delete data at a page-number-for-searching description area in the image data of the table-of-content page and to generate a numeric font of the electronic document page number corresponding to the searching page number according to the result of comparison performed by the page number comparator, such that the searching page number is converted into the corresponding electronic document page number by adding the generated numeric font to the page-number-for-searching description area where the searching page number has been deleted, for a case where the electronic document page number assigned by the page numbering unit is inconsistent with the searching page number at the page-number-for-searching description area.
