摘要: 介绍了一种新的基于乘法元的查表法来实现色彩空间转换。该查表法占用空间小、转换速度快。该文从运算速度和占用空间两方面将该查表法同一次查表法和二次查表法进行了比较,证明了该查表法的优越性。

Abstract: This paper introduces a new LUT based on multiplication to realize the color space transform, which performances better while uses less resource. The paper demonstrates the advantages of the new algorithm by comparing with another two LUTs both in memory and speed.

Key words: color space, YUV, RGB
