1. An image sensor for an electronic device, comprising:

  • a light sensitive element configured to produce a charge corresponding to a light parameter;

    a transfer gate in communication with the light sensitive element;

    a floating diffusion node in communication with the light sensitive element;

    a storage gate in communication with the floating diffusion node;

    a reset gate in communication with the light sensitive element;

    a source follower gate in communication with the storage gate; and

    a row select gate in communication with the source follower gate and the storage gate; and

    a logic chip operably connected to the transistor array chip and in communication therewith;

    whereinthe transfer gate communicates data from the light sensitive element to floating diffusion node;

    the logic chip selectively activates the transfer gate, the reset gate, the source follower gate, the row select gate, and the storage gate; and

    the storage gate has a variable potential.
