Abstract
An optical sensing apparatus includes M light emitting devices, N sensing devices, a control circuit and a processing circuit. M is a positive integer, and N is an integer greater than or equal to 3. The control circuit is arranged for controlling activation and deactivation of the M light emitting devices, and controlling each sensing device to detect a reflected signal reflected from an object when a corresponding light emitting device is activated in order to generate a sensing result corresponding to the sensing device. The N sensing devices generate N sensing results in response to the M light emitting devices. The processing circuit is arranged for calculating position information of the object according to at least the N sensing results and N sensing positions of the N sensing devices, wherein the N sensing positions define at least one geometric plane.
