Patent ID: 8248458

Claim:
A method for producing a multi-focal three-dimensional visually perceptible image that includes objects at different fixation viewing distances and in which a fixation viewing distance of each object in the image substantially corresponds to its vergence when the image is viewed, comprising the steps of: (a) providing both two-dimensional image data and a depth map for voxels of the multi-focal three-dimensional visually perceptible image to be displayed, the depth map indicating a fixation viewing distance of objects in the image; (b) in response to the two-dimensional image data, producing light for displaying voxels of the image; (c) varying a wavefront divergence of the light for the voxels of the image in response to the fixation viewing distance indicated by the depth map; and (d) displaying the image, so that as a function of a viewing distance in the image of objects represented by the voxels, the voxels of the image are displayed with a corresponding divergence, wherein the viewing distance of objects in the image can vary within a maximum range that extends from less than 7 cm to infinity.
