Abstract
A system for forming an integral image includes an optics system spaced between an active digital mask and the first side of an integral lens array, where the integral lens array has a light sensitive material layer spaced relative to the second side of the integral lens array. The active digital mask may provide the image directly to the integral lens array, or the image may be focused on a projection screen placed relative to the integral lens array. The active digital mask can vary the provided image to create a three dimensional image and to account for distortions caused by the optics system or curvature in the integral lens array and/or the light sensitive material. Edible materials may be used for the integral lens array and light sensitive material.
