ABSTRACT:
A color processor for reproducing a color image from color image signals. The processor has a scanner or a generator to obtain color image signals, an A/D converter to generate digital image signals from the color image signal, a density converter to generate density signals from the digital image signals, a controller to control the density converter, and an image reproducer to reproduce a color image according to the density signals. The density converter has a plural conversion data in a ROM memory. Color balance, density control, and picture/character mode change are all performed by selecting data from the conversion data and using the data for the density conversion.
