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.
