To transform color images into gray images quickly and with high fidelity,factors that affect the transformation speed and fidelity were analyzed by comparing existing algorithms.Several methods universal for improving the speed of image transforming programs were proposed,such as expressing gray images in the most suitable bitmap form,developing programs with Visual C++ 6.0 and making full use of its features that could speed up the programs,and so on.Appropriate approximations were introduced to the weight values of red,green and blue component for developing programs with these methods,and it was possible of fast transformation with high fidelity.These advantages of the new algorithm were demonstrated by experiment results of speed,error and visual effect.
