A method and apparatus of employing an X-Y addressable MOS imager to obtain increased dynamic range wherein the X-Y addressable imager as a semiconductor based sensor having an array of pixels formed in rows and column, with a plurality of the pixels formed such that each pixel within the plurality of pixels has a photodetector, a sense node and a transfer mechanism for transferring charge from the photodetector to the sense node, and with a reset mechanism for resetting the sense node to a predetermined potential. An integration period for the photodetector is initiated through operation of the transfer mechanism followed by initiating an integration period for the sense node through operation of the reset mechanism and reading charge from both sense node and photodetector accumulated during their respective integration periods.
