ABSTRACT:
A color image processing apparatus which judges a saturation of an input color image, and performs image processing in accordance with the saturation judgement result, includes an image input means in which a plurality of line sensors for generating color component signals on the basis of different spectral characteristics are parallelly arranged, and means for judging an achromatic area of the color component signals input by the image input means in accordance with a predetermined method. This arrangement performs saturation judgement when a printing operation using only black is performed for a black character or when it is judged whether an original document is a monochrome or color original document.
