Patent attributes
An image processing apparatus which is capable of extracting embedded information from the back side of a printed document without causing degradation of reading efficiency. A scanner unit reads an image on a first side of a sheet. An encoded information processing section extracts embedded information embedded in the image read by the scanner unit. When embedded information indicating that embedded information is embedded in an image on a second side of the sheet is extracted by the encoded information processing section, an automatic second-side reading section reads the image on the second side of the sheet, and the encoded information processing section extracts the embedded information embedded in the image read by the automatic second-side reading section.
