Claim 18:
19. The method of claim 18, further comprising:
transferring first overflow charge of the first charge from the first photodiode, after the first photodiode saturates, to a capacitor to generate a first voltage;
controlling the quantizer to measure, based on the first voltage, a time of saturation of the capacitor by the first overflow charge as the first digital output;
controlling the quantizer to measure, based on the first voltage, a quantity of the first overflow charge transferred by the first photodiode as the second digital output;
transferring second residual charge of the second charge from the second photodiode to the capacitor to generate a second voltage; and
controlling the quantizer to measure, based on the second voltage, a quantity of the second residual charge transferred by the second photodiode as the third digital output.
