Patent ID: 8248490

Claim:
An imaging sensor, comprising: a plurality of imaging pixels arranged in a column; a column sampling circuit coupled to the column; a plurality of sampling channels included in the column sampling circuit, wherein the column sampling circuit randomly selects a first sampling channel from among the plurality of sampling channels to sample a first data signal from a pixel included in the plurality of imaging pixels and wherein the column sampling circuit randomly selects a second sampling channel from among the plurality of sampling channels to sample a second data signal from the pixel; and a random bit sequence generator coupled to provide a random bit sequence to the column sampling circuit, wherein the column sampling circuit is coupled to randomly select the sampling channels from among the plurality of sampling channels responsive to the random bit sequence, wherein the column sampling circuit further includes a register to store at least a portion of the random bit sequence and to provide an output representative of which of the plurality of sampling channels are selected to sample the first and second data signal.
