    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: A method of identifying an iris includes: providing incident beams entering an eye locating at a reference position; setting a first, a second and a third reference point for locating the eye at the reference position; forming a first, a second and a third measuring glint by the incident beams after the eye moves from the reference position to a measuring position, and positions of the first, the second and the third measuring glint corresponding to the positions of the first, the second and the third reference point; capturing an eye image including a first, a second, a third measuring glint image and an iris image; comparing the gray scale value with a threshold gray scale value to obtain the positions of the first, the second and the third measuring glint; and calculating a first and a second variation to obtain an resolution variation of the iris image.
