Abstract
Disclosed herein are a method and apparatus for detecting a preferred color, which is capable of accurately detecting a preferred-color area with a small amount of computations, and a liquid crystal display device using the same. The method for detecting a preferred color includes comparing a hue value of an input pixel with hue reference values and detecting a first preferred-color pixel, and performing a best linear estimation (BLE) operation with respect to the first preferred-color pixel and detecting a second preferred-color pixel.

9. An apparatus for detecting a preferred color, the apparatus comprising:
-
a color coordinate converter which converts image data of an input pixel into a color coordinate; a hue/chroma calculator which calculates a hue value and a chroma value of the pixel using output data of the color coordinate converter; a first detector which compares the hue value of the input pixel with hue reference values and detects a first preferred-color pixel; and a second detector which performs a best linear estimation (BLE) operation with respect to the first preferred-color pixel and detects a second preferred-color pixel. - View Dependent Claims (10, 11, 12, 13, 15)
