Abstract
A multiple photosensor pixel image sensor sense differentiated color components of light. The multiple photosensor pixel image sensor has a plurality of photo-sensing devices formed with the surface of the substrate. Each photo-sensing device has a structure adjusted to convert photons of the light to photoelectrons representative of a magnitude of the color component of the light for which the structure of the photo-sensing device is adjusted. Each multiple photosensor pixel image sensor includes at least one storage node to selectively receive photoelectrons from each photo-sensing device and triggering switches connected to selectively and sequentially transfer the photoelectrons from each of the plurality of photo-sensing devices to the storage node. At least one reset triggering switch is connected to the one storage node to place the storage node to a reset voltage level after integration and sensing of the photoelectrons.
