  • Method and apparatus for detecting preferred color and liquid crystal display device using the same
    Patent number: 8150148
    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.
