Patent ID: 8749656

Claim:
An apparatus comprising: a plurality of column connect switches configured to selectively connect outputs of photosites of a first row of an image sensor to respective column lines; a plurality of electrical storage elements selectively connectable to the column lines; a plurality of sampling switches configured to selectively connect each of the plurality of electrical storage elements to at least one of the column lines; and a plurality of mixing switches configured to selectively connect at least two of the column lines, wherein the column connect switches, the sampling switches, and the mixing switches are controllable to: store selected outputs of the photosites of the first row of the image sensor in the plurality of electrical storage elements; and combine with unequal weighting an even number of the selected outputs of the photosites of the first row stored in the plurality of electrical storage elements to effectuate unequally-weighted average even-factor decimation in the analog domain; and wherein the unequally-weighted average even-factor decimation produces an effective sampling location for a sub-array of the photosites, wherein the sub-array includes adjacent photosites of the same color and the same row or column of the image sensor, wherein the effective sampling location is at a distance from an average location of the photosites of the sub-array.
