A filtering process is carried out on an image signal representing a color image and with an infinite impulse response (IIR) filter to form an unsharp image signal, which represents an unsharp image of the color image. Dynamic range compressing is performed out on the image signal in accordance with the unsharp image signal, and a processed image signal is thereby obtained. A visible image is reproduced from the processed image signal. The dynamic range compressing process can be carried out with relatively few line memories such that the apparatus for carrying out the processing may be kept small, and the printed image having good image quality can thereby be obtained.
