Apparatus and method for converting of pixels from YUV format to RGB format using color look-up tables
Pixels in a YUV format including a Y component representing luminance and U and V components representing chrominance are converted into a RGB format including R, G, and B components respectively representing red, green, and blue colors in order to display images on a video display device such as a CRT (Cathode Ray Tube) or a LCD (Liquid Crystal Display). The present invention relates to an apparatus and a method for converting the pixels from the YUV format to the RGB format using color look-up tables with a small memory capacity. The R component is obtained from the first and second color look-up tables using the Y and V components as indexes, and the G component is obtained from the first, third, and fourth color look-up tables using the Y, U, and V components as indexes, and the B component is obtained from the first and fifth color look-up tables using the Y and U components as indexes.
