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.

Abstract: An image comprising a plurality of interlaced images is provided, and the image is halftone processed according to one or more processes. The image is halftone processed according to a predetermined function depending at least in part on a gray scale level for a given pixel and on gray scale levels for local pixels nearby the given pixel. The predetermined function can operate on a continuous tone version or on a printed-dot model of the image. Alternatively, the predetermined function may include a predetermined error filter where error which is distributed to pixels corresponding to the same interlaced image from which the error accumulates. The image may be post-processed to arrange dots and/or shift columns of pixels to minimize overlap error. The image may be modified to include extra pixels to align the interlaced images under the lenses.

Abstract: An image comprising a plurality of interlaced images is provided, the image is halftone processed according to one or more processes, and the image is printed, for example, using an inkjet printer. The image is halftone processed according a predetermined function depending at least in part on a gray scale level for a given pixel and those nearby the given pixel. The predetermined function can operate on a continuous tone version or on a printed-dot model of the image and may include a predetermined error filter where error is distributed to pixels corresponding to the same interlaced image from which the error accumulates. The image may be post-processed to arrange dots and/or shift columns of pixels to minimize overlap error or modified to include extra pixels to align the interlaced images under the lenses.
