Abstract
A document correction detection system includes a code analysis section that inputs a read image provided by optically reading a print medium on which a document image and a code image are formed and extracts the code image from the read image and a correction detection section that determines a correction made to the document image on the print medium if an anomaly in the code image extracted by the code analysis section is detected.
