Abstract

An image processing device (100) includes: detection means (142 , etc.) for detecting a section width of a pixel coupling portion where a plurality of pixels containing a character portion indicating a character are coupled on an image plane; and identification means (144, etc.) for identifying the character portion according to a statistical distribution of the detected section width.
