Embodiment Construction

[0025] Methods and devices to control the depth and lateral size of reconstructed 3-D images are disclosed. These methods and devices may be used with a novel “Projection” Integral Imaging (PII) system for example.

[0026] One described technique allows pick up of large 3-D objects that may be far away, and also allows the display of their demagnified 3-D images within the depth-of-focus of II systems. It is shown that curved pickup devices (i.e., a curved 2-D image sensor and a curved lenslet array) or curved display devices or both may be used for this purpose. When the lenslets in the curved array have a zooming capability, a linear depth control is additionally possible.

[0027] Two exemplary methods are discussed below alone and also when they are used together. In experiments to demonstrate the feasibility of our method, planar pickup devices may be used (lenslet array, sensor, and display). An additional large aperture negative lens, also referred to herein as an optical path-l...

Abstract

A method disclosed herein relates to displaying three-dimensional images. The method comprising, projecting integral images to a display device, and displaying three-dimensional images with the display device. Further disclosed herein is an apparatus for displaying orthoscopic 3-D images. The apparatus comprising, a projector for projecting integral images, and a micro-convex-mirror array for displaying the projected images.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. provisional application 60 / 706,281 filed on Aug. 8, 2005, which is incorporated herein in its entirety by reference.BACKGROUND OF THE INVENTION [0002] Most 3D display techniques developed to date are stereoscopic. A stereoscopic system may be realized that may display large images with high resolution, however stereoscopic techniques may require supplementary glasses to evoke 3-D visual effects. Additionally, stereoscopic techniques may provide observers with horizontal parallax and a small number of viewpoints. Observation of stereoscopic images may also cause visual fatigue due to convergence-accommodation conflict. [0003] Convergence-accommodation conflict may be avoided by a true 3-D image formation in space with full parallax and continuous viewing points. Holography is one way to form 3-D images in space, but recording full-color holograms for an outdoor scene may be difficult. For example,...
