Abstract
A color multiple sensor pixel image sensor includes multiple photo-sensing devices, a combined photosensing and charge storage device, and multiple triggering switches. Each of the multiple photo-sensing devices is structured for conversion of photons of one differentiated color component to photoelectrons. The combined photosensing and charge storage device is structured for conversion of photons of a principal color photoelectrons and connected to sequentially receive photoelectrons from each of the multiple photo-sensing devices. Each triggering switch is connected such that photoelectrons are selectively and sequentially transferred from each of the multiple photo-sensing devices to the combined photosensing and charge storage device. A reset triggering switch is connected with the combined photosensing and charge storage device and those of the triggering switches connected to the combined photosensing and charge storage device to establish reset voltage level after integration and sensing of the photoelectrons.
