Abstract
A method and apparatus for correcting a preferred color, which is capable of correcting the preferred color in consideration of an input image and the visual characteristics of a person by correcting differences between colors preferred by the person and an average color coordinate of a color to be corrected in the input image, and a liquid crystal display device using the same are disclosed. The method for correcting a preferred color includes 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 and H data of the preferred-color pixel according to differences between the average values of the C and H data and reference values of the C and H data, correcting the L data of the preferred-color pixel according to the average value of the L data according to the hue of the preferred-color pixel, and inversely converting the corrected L, C and H data into image data.
