DISINTEGRATION OF IMAGES MOVING AT HIGH VELOCITIES

This article investigates the effect of spatial disintegration in movi ng images at high object velocities: when the visual system interprets the same object in consecutive fields as different entities. For a 50 -Hz display this effect is found to roughly occur in the velocity rang e of 20-45 degrees/s, and to depend marginally on the resolution level of the objects involved. A more important influence is that of the tr ajectory length of the object: the maximum velocity at which no disint egration occurs is found to depend on it in a linear fashion. A simple model is presented that describes the visual appearance of the disint egration effect as well as explains the data quantitatively. (C) 1996 John Wiley & Sons, Inc.
