Patent ID: 8160356

Claim:
A method for correcting a preferred color, the method comprising: converting data of an input image into lightness (L), chroma (C) and hue (H) data; detecting a preferred-color pixel from the input image; calculating average values of the L, C and H data of the preferred-color pixel; correcting the C data of the preferred-color pixel according to a difference between the C average values of the corresponding preferred-color pixel and a predetermined C reference value of the corresponding preferred-color pixel; correcting the H data of the preferred-color pixel according to a difference between the H average values of the corresponding preferred-color pixel and a predetermined H reference value of the corresponding referred-color pixel; correcting the L data of the preferred-color pixel according to the L average value of the preferred-color pixel or not according to the hue of the preferred-color pixel; and inversely converting the corrected L, the corrected C and the corrected H data into image data according to the hue of the preferred-color pixel or inversely converting the non-corrected L, the corrected C and the corrected H data into image data according to the hue of the preferred-color pixel.
