Abstract
Various embodiments of the present technology may comprise a method and apparatus for pixel readout. The method and apparatus may comprise a pixel array capable of reading out one or more non-rectilinear subsets of the pixel array to form a non-rectilinear primary image. The one or more non-rectilinear subsets may be selected according to a desired rectilinear output image, wherein the rectilinear output image is formed using only the one or more subsets. The primary image may then be transformed to form the rectilinear output image.
