1. A flexible pixel sensor element control system to process a plurality of pixel sensor elements, the system comprising:
- an array of pixel sensor elements; and
a readout and processing circuit wherein the readout and processing circuit reads out and averages a first analog value readout from a pixel sensor element of a first color with a second analog value readout from a pixel sensor element of a second color to produce an average readout value;
a first analog line storage unit, the first analog line storage unit been adapted to store a first line readout from the array; and
a second analog line storage unit, the second analog line storage unit being adapted to store a third line readout from the array, wherein the readout and processing circuit averages a second consecutive line readout from the array with the first line readout stored in the first analog line storage unit to produce a first red-green-blue (RGB) triplet, and wherein the readout and processing circuit averages a fourth consecutive line readout from the array with the third line readout stored in the second analog line storage unit to produce a second RGB triplett.
