Abstract: An optical sensor includes pixels. Each pixel has a photodetector. A readout circuit performs a process over an exposure time where the photodetector is connected to a reverse bias voltage supply to reset a voltage across the photodetector, and the photodetector is disconnected from the reverse bias voltage supply until that the voltage across the photodetector decreases in response to received ambient light. An ambient light level is then determine an based on a number of times the voltage across the photodetector is reset over the exposure time.

Abstract: A feedback module is formed with modules comprising a schedule hardware register module and a computation circuit module. The schedule hardware register module receives a modulation signal and a sensing signal, and schedules and temporarily stores signal values of the sensing signal in successive half modulation cycles in sequence by taking a half modulation cycle as a time interval to obtain a temporarily stored sensing signal which has been scheduled. In each half modulation cycle, the computation circuit module calculates a differential signal value of the temporarily stored sensing signal between the previous two half modulation cycles, and outputs the differential signal value as a signal value of the feedback signal. The schedule hardware register module temporarily stores the feedback signal, and the feedback module feedbacks the feedback signal to an integrated optics chip of the photoelectric sensing system integrated optics chip.
