The reason why the sampled motion in movies or television looks to move smoothly has been explained by apparent motion in the brain. This, however, can be proved clearly as a physical phenomenon by the theory of spatio-temporal sampling and the characteristics of human eyes. Through this, phenomenon related to picture quality, such as blur in the motion areas in LCDs (Liquid Crystal Displays), are made clear. In a similar way, some interactive phenomenon of both motion and color are explained in spatio-temporal frequency domain. In addition, it is pointed out that some examples which have been treated in psychology have nothing to do with the functions of both the brain and the eyes.
