Summary:A method for reading out an image sensor, the method includes the steps of integrating charge in a photodetector with the photodetector at a first capacitance; reading the resulting signal level at a first time with the photodetector at the first capacitance; changing the photodetector capacitance to a second capacitance; and reading the signal level associated with the photodetector at the second capacitance.
