ABSTRACT:
A color image processing apparatus including a read device for reading an original image, a color correcting device for color-correcting input image data using a color-correcting neural network, and an output device for outputting color-corrected image data. The neural network with teacher data, which are in effect learning color data reflecting the visual characteristics of human eyes, using learning data produced by reading a copy image produced based on the learning color data. Accordingly, the neural network can correct colors accurately in a manner to fully reflect the visual characteristics of human eyes, thereby making the color difference between the original image and a copy of the same less noticeable.
