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.

Claim (Index 5):
The pupil tracking device as claimed in  claim 1 , wherein the image sensor is configured to\n capture the first image with a first exposure time and a first gain, and capture the second image with a second exposure time and a second gain, wherein the first exposure time is not equal to the second exposure time or the first gain is not equal to the second gain.
