摘要：The frame frequency used in TV and movies, as well as that used in VDT's, is higher than the critical fusion frequency (CFF). But, because the CFF is determined for a static scene, flicker is perceived when there is a moving object in the dynamic scene. In this research we investigated the fundamental characteristics of flicker perceived in the dynamic scene. The stimulus was a moving edge in the flickering visual field by Maxwlian view, and the flicker frequency exceeded the CFF. The threshold frequency of flicker perception at the moving edge, which rose with the edge velocity from about 6 deg/s, then saturated at about 90 Hz when the edge velocity was about 20 deg/s and then rose again. The result suggests that the mechanisms of flicker perception depends on the velocity of the moving stimulus.
