ABSTRACT:
An image processing apparatus includes a circuit for inputting a plurality of color component signals of a subtractive color system, a circuit for detecting a minimum value signal of the color component signals input by the input means, a circuit for emphasizing a high-frequency component of the minimum value signal detected by the detection means, and a circuit for discriminating a feature of an image in accordance with the minimum value signal whose high-frequency component is emphasized by the emphasizing means.
