A similarity calculation process section registers the largest number of votes of the image of the first document, the index representing the document, and the category of the document into a category table. For the images of the documents being successively read after the document being read first, the similarity calculation process section determines the similarity of the documents based on the result of the voting inputted from a vote process section. When the similarity is lower than a threshold value, determining that the images are not similar to the image of the document registered in the category table, the similarity calculation process section registers the indices representing the documents, the largest numbers of votes of the documents and new categories into the category table, and outputs the result of the determination (classification signal).
