<p>An image display system for providing 3-D images by presenting at least two planar images (27-050, 27-090) at different depths. This invention can be transmitted using much less bandwidth than other 3-D imaging techniques with low in cost and remarkably easy to use. Such apparatus presents the images in positions whereby each is optically spatially separated from the other (often along a co-axial line-of-sight for a viewer (27-200) (i.e. co-aligned)). The display provides traditional 2-D cues, parallax, lateral binocular disparity and depth disparity. Such apparatus employs at least one optical element as a beamcombiner, optionally a semi-silvered mirror or a refractive element (27-035) such as the Fresnel semi-prism. The foreground image plane (27-050) appears transparent except where there are objects, allowing objects on the background image plane (27-090) to be seen when not obscured by foreground objects.</p> |
