Claim 4:
5. The apparatus of claim 4, wherein the quantizer is configured to:
measure the time of saturation based on comparing the first voltage against a static threshold to generate a first decision;
measure the quantity of the first overflow charge transferred by the first photodiode based on comparing the first voltage against a first voltage ramp to generate a second decision; and
measure the quantity of the second residual charge transferred by the second photodiode based on comparing the second voltage against a second voltage ramp to generate a third decision;
and wherein the controller is configured to:
forward the first decision and the second decision to the first memory bank to control a first time when the first memory bank stores a count value from a counter as the first digital output or the second digital output; and
forward the third decision to the second memory bank to control a second time when the second memory bank stores a count value from the counter as the third digital output.
