ABSTRACT:
A reference-character size determination unit determines a reference-character size based on a distribution of sizes of particular continuous image parts, the continuous image parts constituting an image. An image part sorting unit sorts the particular continuous image parts into character image parts and other image parts based on the reference-character size. A rectangle determination unit determines a rectangle for each continuous image part, a size of the rectangle corresponding to a size of the corresponding continuous image part. The reference-character size determination means determines the reference-character size based on a distribution of sizes of the rectangles. The image part sorting means sorts the particular rectangles into rectangles for the character image parts and rectangles for the other image parts based on the reference-character size. The character image part integrating unit integrates the particular character image parts with each other when particular character image parts have a predetermined character relationship.
