图像从输入设备到显示器观察，再到输出设备或最终的图像文件的流程中，由于不同设备的呈色机理、呈色特性、所采用的呈色空间不同，造成颜色信息在不同的设备间传递时出现了偏差，要维护原始的色彩是非常困难的。借助PCS空间，通过多项式分区回归的方法进行色彩空间转换。实验结果表明，这种方法能够实现彩色图像显示系统的色彩还原且精度较高。

In the course of image processing, an image enters the input device, experiences observation in the monitor, and arrives at the output device or the final image file. In this process, due to the different coloring mechanism, colorimetric characteristics and colorimetric space of different devices, there occurs color distortion when color information passes between different devices, so it is rather difficult to maintain the original color. With the PCS space, this paper converts color spaces by the method of polynomial zone regression. The result shows that this method can achieve color reproduc-tion for color image display system with high precision.
