When I considered the flicker-motion problem of 24P-DV camera before, I derived this diagram based on the knowledge of the center shutter.
(DV camera has not almost inclination.)
However, the diagram is exaggerated.
Because the inclination of the diagram is bit part of the entire diagram, the existence of the effect which the Manual of Eclair says is not certain.
Out of curiosity, I will observe the difference of image shot by ACL and ST after this.
