本文提出用白光按两张图片之间的差别假彩色编码的一种方法.证明了用不同颜色的两个光源足以检验人眼所能同时区分的两张连续灰度图片之间的差别,并用电视模拟系统对假彩色编码输出像进行了选色和微分处理,增强了所需要的差别信号.理论分析与实验相符.最后,讨论了这种方法可能的实际应用.
This paper proposes a method of false color coding using white light as the difference between two pictures. It is proved that using two light sources of different colors is enough to test the difference between two consecutive gray pictures that the human eye can distinguish at the same time. The TV analogue system performs color-selective and differential processing on the false color coded output image and enhances the required differential signal.Theoretical analysis is consistent with the experiment.Finally, the possible practical application of this method is discussed.
