Abstract: There is provided a pupil tracking device including an active light source, an image sensor and a processing unit. The active light source emits light toward an eyeball alternatively in a first brightness value and a second brightness value. The image sensor captures a first brightness image corresponding to the first brightness value and a second brightness image corresponding to the second brightness value. The processing unit identifies a brightest region at corresponding positions of the first brightness image and the second brightness image as an active light image.

Abstract: The present invention discloses a displacement detecting device including a displacement sensing module, an input module, a distance sensing module, and a processing module, and a power saving method thereof. The processing module is electrically connected to each module. The input module is used to supply non-contact operation. The distance sensing module is used to detect the distance between a body and the displacement detecting device, and then produces a sensing value. The processing module selectively control the displacement sensing module and the input module to be turned on or turned off according to the sensing result of the distance sensing module. The displacement detecting device turns on the displacement sensing module when the sensing value is less than a first default value, and turns on the input module and turns off the displacement sensing module when the sensing value is greater than a second default value.
