Abstract: An operator controllable apparatus which adjusts the color of a copy being reproduced from a multi-colored original document. The original document is scanned and a set of primary color densities therein measured. The measured set of primary color densities is changed to a set of colorimetric coordinates. The operator adjusts the set of colorimetric coordinates so that the copy has the desired hue, saturation and darkness. The operator adjusted set of colorimetric coordinates is transformed into a set of subtractive primary color densities. This set of subtractive primary color densities controls the marking engine to form a copy having the desired hue, saturation and darkness.

Abstract: A color image processing apparatus in which a latent image corresponding to one of the color components of an original document is recorded on an image receiving member. The original document is scanned and a plurality of color components of the original document are detected. Color signals, representative of each one of the plurality of color components detected, are generated. As the latent image is being recorded on the image receiving member, those regions of the latent image wherein the color signals have a preselected relationship to one another are erased.
