Why is Sampled Motion Possible?

Abstract

Although sampled motion in TV and movies has been considered to be self-evident, it does not seem to satisfy the sampling theory. Here, the fundamental properties of TV signals in the spatio-temporal domain are rather different from those in the horizontal-vertical domain. By analyzing the motion in the spatio-temporal frequency domain with assumption of these properties and those of an eye system, it is made clear that the motion satisfies the theorem.
