Abstract
The subject matter of the invention is to add information to image data of multicolor image and monochromatic image. An image processing apparatus capable of adding information on raw data performs a dispersion conversion on the spectrum of the additional information by multiplying a code sequence of the PN sequence generatorby the additional data which is inputted from the input terminaland converted into serial data in P/S converter. At this time, the data sequence transmitted from the image signal processorto the printer engineis converted by the scan converterto correspond to the spatial axis for desperation. The converted data sequence is added to the output from the adderby the adder, and reconverted to the original scan by the scan inverter
