Abstract This invention relates to colour optimization self-adaption chroma compersation method for electronic image and the apparatus therefor. The method includes to present compensation characteristics with different grains in all colour ganut units classified by visual characteristics; according to the experimental data for obtg. best watching effect, to proceed real-time distinguishing of signal involved in colour ganut unit and then proceed corresponding compensation, to make main wavelength, chroma and relative luminance of all image colour self-adapting to requirement of best colour reprodn., thus obtg. high quality colour image. Said method can eliminate partial bad chroma distortion which can't be avoided by prior art products and improve adaptability of apparatus for receiving enrironment.
