Patent ID: 7649688

Claim:
A method for providing auto-stereo three-dimensional views, the method comprising: providing an image on a substrate of sufficient transparency to allow light therethrough, said image comprising a plurality of interspersed views made up of pixels organized in a plurality of cells, each cell containing a plurality of said pixels that together make up a predetermined range of views for a region of the image in which the cell is located, each cell having a maximum height in a first direction that tapers continuously to a minimum height and being contiguous with at least one adjacent cell in a second direction perpendicular to the first direction so as to together form one of a plurality of cell rows, said cell rows lying adjacent to each other in the first direction with cell positions being staggered in the second direction from one row to an adjacent row such that a maximum cell height in a first row aligns substantially with a minimum cell height in an adjacent row, and cells in adjacent rows lie partially adjacent to each other in the second direction; placing a barrier screen in front of said image to provide a parallax effect, said barrier screen having a plurality of rows of staggered apertures through which light can pass, said apertures being elongate in the first direction and having a height in the first direction approximately equal to the maximum height of the cells, each aperture being positioned adjacent to one of the cells; providing a plurality of dark rippled lines that separate the cell rows on the image substrate; and illuminating said image from behind using a light source.
