MICRO-OPTIC DEVICE PROJECTING MULTI CHANNEL PROJECTED IMAGERY
First Claim
1. A micro-optic device for projecting an image, the device including:
- a substrate;
a plurality of image elements, arranged on the substrate, in an image plane; and
a plurality of focusing elements arranged in a two dimensional array on the substrate, each focusing element focusing light to a focal point on the image plane and magnifying any portion of an image element falling within the focal point to thereby produce a projected image pixel projected to a user at a plurality of viewing angles, the focal point having an extent smaller than the image element, wherein;
each image element including an image sub-element discernible from elsewhere in the image element,brightness of each projected image pixel being dependent on the proportion of the focal point filled with the image sub-element, andeach image sub-element has one or more attributes in the image plane and the or each attribute corresponds to a pre-defined brightness at a particular angle of view, such that the projected image pixels together project the image, and at other angles of view the brightness of the projected image pixel varies, in a defined relationship according to the or each attribute, and wherein image pixels having a same brightness at a particular angle of view are produced by image elements having sub-elements with identical attributes.

Abstract
A micro-optic device, including: a substrate; a plurality of image elements in an image plane; and a plurality of focusing elements, each focusing element focusing light to a focal point on the image plane and magnifying any portion of an image element falling within the focal point to thereby produce an image pixel projected to a user at one or more viewing angles, the focal point having an extent smaller than the image element, wherein each image element includes an image sub-element having a different discernible level of brightness to elsewhere in the image element, the brightness of each projected image pixel being dependent on the proportion of the focal point filled with the image sub-element, and wherein each image sub-element has one or more attributes in the image plane, such that, from a given viewing angle, the brightness of each projected image pixel is dependent on each attribute of each image sub-element.
