Abstract: A system for compensating for photodiode errors includes a live photodiode configured to be exposed to a light source and to output a live signal. The system further includes a reference photodiode located proximate to the live photodiode and configured to be isolated from the light source and to output a reference signal. The system further includes a controller configured to generate a compensated output signal by subtracting the reference signal from the live signal.

Abstract: An electronic device includes a photodiode, a switching circuit, a readout circuit, and an energy storage device. The photodiode includes a first terminal and a second terminal and is configured to generate a signal according to a light. The switching circuit is electrically connected to the first terminal and the second terminal. When the electronic device operates in a sensing mode, the switching circuit electrically isolates the photodiode from the energy storage device so that the signal is provided to the readout circuit. When the electronic device operates in a charging mode, the switching circuit electrically connects the photodiode to the energy storage device so that the signal is provided to the energy storage device.

Abstract: There is provided an optical sensor including a photodiode, a wave converter, a pixel array and a processor. The photodiode detects ambient light flicker to generate sine waves. The wave converter converts the sine waves to square waves. The processor uses a sampling frequency to count the square waves, and identifies whether the ambient light flicker is well detected according to a counting value of each square wave and a counting value variation of multiple square waves within a count period to accordingly determine whether to adjust an acquiring phase of the image frame.
