Abstract
A method and apparatus for performing color image processing includes inputting a standard color image signal, performing color correction on the standard color image signal using a predetermined parameter to produce a color-corrected standard color image signal, and encoding the color-corrected standard color image signal to produce an encoded standard color image signal. The encoded standard color image signal is decoded to produce a decoded standard color image signal. The predetermined parameter is determined on the basis of both the standard color image signal and the decoded standard color image signal.
