摘　　要：本文简单介绍了几种常见的区域LCD(液晶显示器)动态背光提取算法并分析其优缺点,在此基础上提出了一种基于动态阈值的LCD背光调节新算法。该算法在平均亮度的基础上根据图像细节所占的比例适当的增加背光亮度,这样能够有效地保持图像的质量,降低背光的功耗。Various backlight algorithms are analyzed comprehensively in the article. Moreover, considering the real-time characteristics of LCD （liquid crystal display）, a new algorithm based on dynamic threshold is proposed. The algorithm is based on the average backlight, combines with the proportion of the image details to adjust the backlight, and can maintain the quality of the image and reduce the power consumption effectively.
