VARIABLE-DEPTH STEREOSCOPIC DISPLAY
First Claim
Patent Images
1. A method comprising:
- receiving a first distance at which a viewer is disposed relative to a stereoscopic display;
determining, based on the first distance, a second distance by which to change a front focal distance of a lens structure of the stereoscopic display; and
causing the focal distance of the lens structure to change by the second distance effective to display a stereoscopic image at the first distance.

Abstract
This document describes various techniques for implementing a variable-depth stereoscopic display. A first distance at which a viewer is disposed relative to a stereoscopic display is received. Once received, a second distance by which to change a front focal distance of a lens structure of the stereoscopic display is determined based on the first distance. The front focal distance of the lens structure is then caused to change by the second distance effective to display a stereoscopic image at the first distance.

8. An optical system comprising:
-
two or more light sources individually selectable to emit light, each of the two or more light sources associated with a respective light guide having an optical path length that is different from an optical path length of a light guide associated with another of the two or more light sources; a lens structure configured to receive light from one of the light guides associated with one of the two or more light sources and emit light useful to display stereoscopic imagery to a viewer; a controller configured to; determine whether the viewer is within a front focal plane of the stereoscopic display; and if the viewer is not in the front focal plane of the stereoscopic display, select another of the two or more light sources to change the front focal plane of the stereoscopic display. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system comprising:
-
a first light source and a second light source individually selectable to emit light; a first light guide and a second light guide, the first and the second light guides configured to receive the light emitted from the first or the second light source respectively, the first light guide having an optical path length that is different from an optical path length of the second light guide; a lens structure configured to receive the light from the first or the second light guides and emit light useful to display stereoscopic imagery to a viewer; and a controller configured to select, based on an distance from the lens structure to the viewer, one of the first or the second light sources effective to set a front focal distance of the lens structure such that the front focal distance corresponds to the distance to the viewer. - View Dependent Claims (16, 17, 18, 19, 20)
