摘要： An artificial vision system which simulates a retinal image obtained when a subject views a standard measuring object by turning his eyeball with respect to an eyeglass lens. An artificial vision lens system corresponding to an ocular optical system and a CCD camera having a CCD plane corresponding to a retina are provided within an artificial vision camera. Rotary movement of the eyeball centering on its turning point with respect to an eyeglass lens is simulated by turning the artificial vision camera in the horizontal direction by a rotary stage and by turning the glass lens in the vertical direction by another rotary stage. Turning and parallel movement mechanisms are provided under a stage on which the lens and the artificial vision camera are mounted so that the artificial vision camera always points toward a predetermined position on the standard object as viewed through the lens.
