Abstract

A system, device, and method for enhancing depth perception in a two-dimensional image is disclosed providing the induction of retinal disparity in the eyes of the viewer by the placement of a visually identifiable object in front of the two-dimensional image. Upon fusion of such retinal disparity in the viewer, the viewer experiences the enhancement depth perception in the two dimensional image.
