<p>It is an object to avoid suppression of color signals before a green color signal (G) reaches a saturation detection level (Gdet) or before each of color signals (R and B) reaches its saturation level to thereby substantially faithfully reproduce color of an object. To this end, a high luminance color suppressing circuit comprises a virtual luminance signal generator for generating a virtual luminance signal (Y) based on one or at least two of input color signals (Rin, Gin and Bin), a coefficient generator for generating a first through a third coefficient (K1) through (K3) based on a saturation detection level (Gdet), a virtual detection level (Gth), and maximum output levels (Rmax and Bmax), and an output color signal generator for generating output color signals (Rout, Gout and Bout) based on the virtual luminance signal (Y), a minimum coefficient (K0) and the color signals (Rin, Gin and Bin).</p> |
