摘　　要：LCM的驱动控制模块性能往往较低,为了使彩色液晶显示模组的图像彩色得到增强,并保持原来的色调不变,提出了一种适于性能较低的控制模块的图像增强算法;算法采用彩色空间灰度值缩放相同的比例因子,且灰度值不溢出,像素RGB分量得到相同增强。实验结果表明,该算法运算复杂度小、增强后图像彩色丰富,综合性能优良。Because LCM＇s drive control module performance is low,in order to make the color LCD module＇s image color enhanced and keep the original color unchanged,an image enhancement algorithm suitable for low performance control module was proposed.The algorithm uses color space grayscale value with the same scaling of scale factor and the gray value does not overflow.The pixel RGB components will obtain the same enhancement.The experimental results show that the computational complexity of the algorithm is small,the color of the enhanced image is richer,and the overall performance is excellent.
