Abstract:
1. A method comprising the steps of: providing a plurality of image sensors at positions in a row arrangement non-uniformly distributed with varying distances between each adjacent pair of sensor positions determined according to a first predictable deterministic schema, wherein said first predictable deterministic schema avoids harmonics and integral multiple of spacings that produce Moiré patterns in a captured digital image, said first predictable deterministic schema comprising a cyclic redundancy check polynomial; selectively sampling an image by sequentially exposing image portions to said row arrangement to obtain a first set of data samples representing non-uniformly spaced points according to said first predictable deterministic schema in said image; and producing a sampled digital image containing said first set of data samples associated with a reference identifier of said deterministic schema, wherein said digital image comprises pixel data at points spaced according to said first predictable deterministic schema and wherein said image is free of Moiré patterns.
