Abstract:
1. 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 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.
