1. A charge coupled device (CCD), comprising:
a first pixel and a second pixel, with each of the first and second pixels including a photodetector and a corresponding first transfer gate coupled to the photodetector;
a second transfer gate having an input coupled to an output of each first transfer gate of the first and second pixels;
a potential barrier coupled to an output of the second transfer gate; and
a capacitor coupled to the output of the second transfer gate;
wherein the capacitor is a first capacitor and the CCD comprises a second capacitor and a switch coupled between the output of the second transfer gate and the second capacitor; and
wherein the second capacitor has a higher capacitance than the first capacitor.
