Claim 23:
24. The apparatus of claim 21, wherein the processing circuit is configured to:
perform a third quantization operation comprising:
comparing the first voltage against a first static threshold voltage to generate a fourth decision; and
generating, based on the fourth decision, a third digital value from the counter; and

output one of the first digital value, the second digital value, or the third digital value to represent the intensity of light received by the photodiode; and
wherein the counter is reset based on at least one of: the first ramping threshold voltage reaching a first voltage break point during the first quantization operation, the second ramping threshold voltage reaching a second voltage break point during the second quantization operation, or a time break point is reached during the third quantization operation.
