Patent ID: 8184190

Claim:
An image sensor fabricated on a surface of a substrate for sensing light impinging upon said image sensor, said image sensor comprising: an array of a plurality of color multiple sensor pixel image sensors arranged in rows and columns upon said substrate for sensing said light impinging upon said image sensor, each of said multiple photosensor pixel image sensor comprising: a plurality of photo-sensing devices formed within said surface of said substrate, each photo-sensing device having a structure adjusted to convert photons of said light to photoelectrons representative of a magnitude of a color component of said light for which said structure of said photo-sensing device is adjusted; at least one storage node formed within said surface of said surface and connected to selectively receive photoelectrons from each of said plurality of photo-sensing devices; a plurality of transfer gating switches, each transfer gating switch connected between one of said plurality of photo-sensing devices and said storage node to selectively and sequentially transfer said photoelectrons from each of the plurality of photo-sensing devices to said storage node; at least one reset triggering switch in communication with said storage node and said transfer gating switches connected to said one storage node to place said storage node to a reset voltage level after integration and sensing of said photoelectrons; a row control circuit in communication with rows of said array of plurality of color multiple sensor pixel image sensors that generate reset control signals, transfer gating signals, and row selecting signals for providing a global shuttering and a rolling shuttering of said array of a plurality of color multiple sensor pixel image sensors; and a column clamp, sample and hold circuit in communication with each column of the array of the plurality of color multiple sensor pixel image sensors to clamp, sample, and hold said conversion electrical signals from selected rows of the plurality of color multiple sensor pixel image sensors and from said sampled and held conversion electrical signals generating an output signal representative of a number of photons impinging upon each color multiple sensor pixel image sensor of said row of selected color multiple sensor pixel image sensors.
