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.
