Abstract
An imaging system may include an image sensor with an array of pixels arranged in rows and columns. Row driver circuitry may be coupled to the pixels and may address a given row of the pixels based on a row address. Row randomization circuitry may be coupled to the row driver circuitry to dither the row address and therefore randomize the order in which rows of a given column are read out over column lines to sample and hold circuitry that includes a plurality of capacitors for each column. The imaging system may include a multiplexer that de-randomizes the order of the rows after passing through the sample and hold circuitry. Alternatively or additionally, the order in which the plurality of capacitors is used to store the signals from each column may be randomized. In this way, fixed pattern noise in an output image may be reduced or eliminated.
