Zusammenfassung:Apparatus, systems and methods for image sensor leakage and dark current compensation are disclosed. In one implementation, a method is disclosed including accumulating charge on a first hold capacitance of an imaging pixel, and accumulating charge on a second hold capacitance of the pixel in response to the first hold capacitance reaching a predetermined voltage level. Other implementations are disclosed.
