Abstract
A color image processing apparatus includes a storage device for storing input image data for one frame and a discriminator for analyzing the color image data stored in the storage device. In the color image processing apparatus, the discriminator discriminates the type of the stored color image data utilizing a membership function.
Claims22
A color image processing apparatus comprising:
- inputting means for inputting electrical color image signals;
- and
- discriminating means for analyzing the electrical color image signals, so as to discriminate a type of the electrical color image signals using a plurality of membership functions, each of which relates to a respectively different characteristic extracted from an electrical color image signal;
- wherein the type of the electrical color image signals corresponds to a source of the electrical color image signals.
