When the light source is turned on and off, the optical sensing element senses the surrounding light to generate a first current and a second current, respectively. The integration circuit integrates the first current and the second current to generate a first integration signal and a second integration signal respectively for determining whether an object is approaching. When the light source is turned on, the present second integration signal is stored, and a stored first integration signal is used as a starting value to integrate the first current. When the light source is turned off, the present first integration signal is stored, and the stored second integration signal is used as a starting value to integrate the second current.
