1. An image processing apparatus for outputting image information to image forming means which forms an image on a medium, comprising:
- superposing means for superposing predetermined additional information on input image information; and
processing means for performing modulation of the image information superposed with the additional information by said superposing means, wherein when said image forming means forms an image in accordance with the image information obtained by performing demodulation of the image information modulated by said processing means, said superposing means superposes the additional information so as to make it difficult for the human eye to identify said additional information.

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.

23. An image processing apparatus comprising:
-
means for inputting an image signal from an external equipment;
means for reading an original image;
means for synthesizing a first image signal input from said external equipment with a second image signal read by said reading means to generate a third image signal; and
means for superposing predetermined additional information on the third image information, wherein the third image signal is formed prior to superposition by said superposing means. - View Dependent Claims (24, 25, 26, 27, 28)
