PROBLEM TO BE SOLVED: To accurately identify even documents of a similar basic structure. SOLUTION: An entire image identification part 5 identifies a document by collating an input slip image and the entire image of the document registered in a dictionary 3. Then, for the identified one or a plurality of documents, a partial image identification part 6 further identifies the documents by collating document names or the like. A part of the image is character information. When registered image are generated, a part of registration object images is registered and a most different part between already registered images and the registration object image is registered. Only when the plural kinds of the registered images similar to the image of a routine slip are present, a part of the images is collated. |
