ABSTRACT:
A color copier operable both in monochromatic and full-color copying modes is controlled by a central processing unit programmed to exercise a real-time control of operation by detecting image characteristics of an original to be copied if a monochromatic copying mode is selected. If a full-color copying mode is selected, the image characteristics are preliminarily detected by scanning before a copying operation is started.
