Abstract
A two-color copying machine performs two scannings of an original to supply image data respecting the original to an image sensor. In one of the scans, a complementary color filter is inserted in the optical path to absorb a particular chromatic color. Achromatic printing is carried out using the image signal generated without the filter, while printing in the chromatic color is carried out using a combined image signal generated with said complementary filter in place.
