Image processing device, image processing method and image processing program

摘要

MFP 100 obtains document image data by reading an image of an IC-tagged document by means of image scanning unit 150, and writes it into the IC tag of the document as archive information of the document image by means of IC-tagged reading/writing unit 140. It also writes the differential image data obtained by extracting the difference between the document image data and the image data related to the archive information stored in the IC tag of the document as the archive information of the document image. Moreover, MFP 100 is capable of reading the desired archive information from the IC tag of the document, and printing or deleting it. This makes it possible to accumulate and use the archive information of the document image in the document itself when the document image is updated multiple times by handwriting notes, etc.
