In the document identification apparatus, a ruled line feature extraction section determines a black pixel. ratio of a document to beg identified, and adds the black pixel ratio for each blocks to extract a ruled line feature. A ruled line feature verification section verifies the ruled line feature with a ruled line feature already registered in a ruled line feature dictionary to thereby identify the document. If identification is not possible with this procedure, a details judgment section verifies the image data in a specific area with the image data (characters or the like) registered in a specific area dictionary.
