摘要： 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.

摘要： 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.
摘要翻译：一种操作者可控制的装置，其调节从多色原始文件再现的副本的颜色。扫描原始文件，并测量其中一组原色浓度。测量的原色密度组被改变为一组比色坐标。操作员调整比色坐标系，使复印件具有所需的色调，饱和度和黑度。操作者调整的比色坐标系被转换成一组减色原色浓度。该组减色原色浓度控制标记引擎以形成具有期望色调，饱和度和黑暗度的拷贝。
