ABSTRACT:
An apparatus and method for adding information to image data of a multicolor image and a monochromatic image includes the performing of a dispersion conversion on the spectrum of additional information to be added to the image data by multiplying a code sequence of a PN sequence generator by the additional data which is inputted from an input terminal and converted into serial data in a P/S converter. At this time, the data sequence transmitted from an image signal processor to a printer engine 107 is converted by a scan converter to correspond to the spatial axis for dispersion. The converted data sequence is added to the output from an adder by another adder 110, and reconverted to the original scan by a scan inverter.
