Normal vision is a dynamic process, which depends on the constant motion of the retinal image that is produced by eye movements. Studies in which these natural motions have been eliminated, and in some cases replaced by artificial ones (under the control of the investigator), reveal important properties of the visual process. In this paper, we describe the effects of image stabilization on luminous and chromatic contrast sensitivity, explore the ways in which sensitivity varies with velocity, compare the effects of artificial image motion with those of natural eye movements, and report some surprising properties of the mechanism responsible for the residual detection of stabilized images.
