Abstract
Image processing apparatus with a color saturation controller for processing a color image signal to be printed derives color difference signals from an incoming color image signal, detects a minimum difference value between an allowable dynamic range of color difference signals and the derived color difference signals, and generates a coefficient value based on the detected minimum difference value. The levels of the derived color difference signals are corrected by multiplying the generated coefficient value and the color difference signals. The dynamic range of the input color difference signals is extended by such multiplication within a scope not causing any overflow, and the color saturation can be directly corrected without changing the color phase of the image signal.
