Abstract:
1. An image forming apparatus for composing an original image and control information for controlling the copying of the original image, comprising: a background image formation unit that generates a background image which includes first pattern images two dimensionally arrayed at predetermined spatial intervals so as to express the control information code data that is detectable when the copying operation is performed by using a predetermined apparatus being made to correspond to the first pattern image; an image composing/generating unit that generates a composite image by composing the original image and the generated background image; an output unit that outputs the composite image; a first control information acquisition unit for acquiring first condition information indicating if copy condition as an example of the condition information is present; a second control information acquisition unit for acquiring information on copy condition as an example of the condition information for limiting the copying operation when the copying condition is present, within fixed limits; and an encoding unit for generating copy condition code data by error correction encoding information on the copy condition acquired by the second control information acquisition unit.
