Image processing method and apparatus for adding identifying information to an image portion and forming the portion at a lower of plural resolutions
First Claim
1. An image processing controller for supplying image data to an image forming apparatus for forming an image on a medium at a plurality of resolutions, comprising:
- input means for inputting image data;
adding means for adding information for identifying the image forming apparatus, to the input image data; and
control means for controlling the image forming apparatus such that the portion of the image to which the information is added is formed at a lower resolution of the plurality of resolutions.

Abstract
An image processing apparatus for color image formation that adds a specific pattern to identify the apparatus more reliably, to image information. For example, in a bit array of a printer'"'"'s identification number in binary representation, if one bit has a value "0", the value of input multivalued image data in a M-th line in a subscanning direction is decremented by "30". On the other hand, if the bit value is "1", the data of the input multivalued image data is incremented by "30". If the data value has been incremented by "30" in the M-th line, data value at a position immediately below the position where the data valued has been incremented (decremented) in the next (M+1)-th line is decremented by "30", while if the data value has been decremented by "30" in the M-th line, data value at a position immediately below the position where the data value has been incremented (decremented) in the next (M+1)-th line is incremented by "30".
