Abstract
Predetermined additional information is superposed as a dot pattern on image information read by an image scanner, and the image information superposed with the additional information is modulated. The modulated information is demodulated and recorded on a recording medium to perform a series of operations, i.e., to simultaneously satisfy both pattern addition and modulation/demodulation.
