Abstract
A proximity detecting apparatus for detecting a proximity event includes a capacitive sensing device, an auxiliary detecting device, and a controller. The capacitive sensing device is arranged for generating a capacitive sensing output. The auxiliary detecting device is arranged for detecting an operational status of an electronic device in which the capacitive sensing device is disposed and accordingly generating a status output. The controller is arranged for detecting the proximity event according to the capacitive sensing output and the status output.
