摘要
A character box extracting unit extracts a line forming a character box. Then, the character box intersection calculating unit calculates the intersection of the character box with a character pattern. An intersection corresponding unit associates intersections with each other based on the directional property of character lines, distance between the character lines, etc. An in-box character extracting unit extracts a virtual image according to the association information between the intersections. A character size evaluating unit obtains from an optional character string an average character size of a character including the virtual image, and extracts a true character pattern by removing a redundant virtual image based on the average character size. A character structure analyzing and evaluating unit obtains from a prepared table a true image corresponding to the virtual image and extracts a true character pattern, thereby correctly extracting the pattern from the image in which the line crosses the pattern.11
