Abstract:
1. An image processing apparatus comprising: a reader unit configured to read an image on a first side of a sheet; a processing unit configured (i) to judge whether or not embedded information is present in the image on the first side of the sheet, (ii) to judge whether or not copy restriction information indicative of copy restriction is present in the image on the first side of the sheet, and (iii) to judge whether or not double-sided information indicating that embedded information is present on both sides of the sheet is present in the image on the first side of the sheet; and a copying unit, wherein said reader unit is configured to operate to read an image on a second side of the sheet when said processing unit (i) judges that embedded information is present in the image on the first side of the sheet, (ii) judges that the copy restriction information is present in the image on the first side of the sheet, and (iii) judges that the double-sided information is present in the image on the first side of the sheet, wherein said processing unit is configured to judge, when said reader unit operates to read an image on the second side of the sheet, (i) whether or not embedded information is present in the image on the second side of the sheet, (ii) whether or not copy restriction information indicative of copy restriction is present in the image on the second side of the sheet, (iii) whether or not copy restriction removal information indicative of a condition for removing the copy restriction is present in the image on the second side of the sheet, and (iv) whether or not double-sided information indicating that embedded information is present in both sides of the sheet is present in the image on the second side of the sheet, wherein said processing unit is configured to determine, when it is judged that embedded information, copy restriction information, copy restriction removal information, and double-sided information are present in the image on the second side of the sheet, whether or not copying is permitted, based on the copy restriction removal information, and wherein said copying unit is configured to operate, when said processing unit determines that copying is permitted, to perform printing based on the image read by said reader unit on the first side of the sheet or on the second side of the sheet.
