| Abstract: |
An image processing apparatus reads color images, identifies the colors of an read color image, converts the color image into a monochrome image, synthesizes color recognition information on the monochrome image, and prints the resulting synthesized image as a monochrome image. As a result, even if a low-priced printer is employed, it is possible to provide a monochrome image permitting recognition of the colors of the color original, or quick identification of differences among the colors thereof. Moreover, this allows a user to specify a desired graphic pattern to be associated with a given color, and to obtain collation tables independently of the monochrome image, or to print the specified graphic pattern with any variable magnification power.
