In this invention, a chroma compensation circuit includes: a hue detector for employing input R, G and B color signals to determine which hue areas to which the R, G and B color signals belong; a compensation signal generator for employing the output of the hue detector to generate hue compensation signals; and a compensation addition unit for performing a matrix operation for the input R, G and B color signals to generate color difference signals, for performing chroma compensation for the color difference signals by employing the hue compensation signals generated by the compensation signal generator, and for performing an inverse matrix operation for the color difference signals obtained by the chroma compensation and outputting R, G and B color signals.
