ABSTRACT:
A two-dimensional array of non-uniformly spaced pixels having a plurality of overlaid pixel sets for avoiding moiré patterns in digital images by avoiding producing an inherent “frequency” or pattern that may interfere with details or harmonics present in the image source, thereby eliminating the occurrence of moiré patterns and the need for application of image processing to remove Moiré patterns. A first set of pixels, (imaging sensors or display elements) are arranged along a two axes according to a non-uniform predictable process. The first set pixels spacing inherently produces non-uniformly spaced and sized “gaps”, in which additional sets of pixels potentially having a different characteristics from the first set, may be placed, thereby yielding an array comprised of multiple overlaid arrangements of non-uniformly spaced pixels. As such, images samples from or displayed on the additional sets of pixel sensors also avoid production of Moiré patterns.
