Abstract:
1. A document processing apparatus, comprising: an image reader for scanning an original manuscript which is not updated to generate first image data on said original manuscript and for scanning an updated manuscript to generate second image data on said updated manuscript; a text information extraction part for extracting first text information from said first image data and extracting second text information from said second image data; an updated portion detector for detecting an updated portion of said updated manuscript on the basis of said first text information and said second text information; an electronic document generator for generating an electronic document of said updated manuscript on the basis of said second image data; a storage controller for generating display data of said updated portion on the basis of a detection result on said updated portion and storing said display data into said electronic document; a header item group extraction part for extracting a plurality of header items in said original manuscript as a first header item group from said first text information and extracting a plurality of header items in said updated manuscript as a second header item group from said second text information; and a node group setting part for hierarchizing said first header item group to construct a node group having a first tree structure and hierarchizing said second header item group to construct a node group having a second tree structure, wherein said updated portion detector compares said node group of said second tree structure with said node group of said first tree structure to thereby detect said updated portion.
