Abstract: The light detecting device provided by the present disclosure includes a reset circuit, a photoelectric conversion circuit, a voltage follower circuit, a selection circuit, and a light fluctuation detecting circuit. The light fluctuation detecting circuit is connected to each of a light fluctuation detection control terminal, a photoelectric node and an input terminal of the voltage follower circuit. The light fluctuation detecting circuit is configured to enable or disable a connection between the photoelectric node and the input terminal of the voltage follower circuit. When the light fluctuation detecting circuit is turned off, a drain current of the light fluctuation detecting circuit may change as the brightness of light received by the light fluctuation detecting circuit changes. The voltage at the output node is used to determining brightness of light received by the photoelectric conversion circuit and whether is a fluctuation in the in the brightness of the light.
