Abstract:
1. An image processing apparatus comprising: a region division unit configured to divide a document image that is specified as a processing target page from among a document image containing a plurality of pages into a body region, a caption region, and an object region to which the caption region is appended; a character information acquisition unit configured to acquire character information included in each of the body region and the caption region divided by said region division unit; an accumulation unit configured to divide the character information acquired from the body region into predetermined set units and to accumulate the character information and position information of the divided set unit in a memory; a page drawing data generation unit configured to generate page drawing data of the document image of the processing target page and to output the page drawing data; a repeating unit configured to repeat execution of processes by the region division unit, the character information acquisition unit, the accumulation unit, and the page drawing data generation unit for each page of the document image containing the plurality of pages as the processing target page, in order; an anchor term extraction unit configured to, after the processes by the region division unit, the character information acquisition unit, the accumulation unit, and the page drawing data generation unit have been executed for all pages of the document image containing the plurality of pages by repeating by the repeating unit, extract an anchor term from the character information acquired from the caption region; an anchor term search unit configured to search, based on the character information accumulated in the memory for each set unit, for the set unit including the anchor term extracted by said anchor term extraction unit; a link information generation unit configured to generate link generation information that associates the set unit found by said anchor term search unit with the object region to which the caption region including the anchor term is appended; and an electronic document data generation unit configured to generate, based on the link generation information, electronic document data including a program code to be used to generate a description for representing a link function between the object region and the anchor term in the set unit and the page drawing data outputted by said page drawing data generation unit, wherein the program code included in the electronic document data dynamically generates the description for representing the link function between the object region and the anchor term in the set unit by operating when using the electronic document.
