    Abstract: There is provided a portable electronic device including a backlight module, an ambient light sensor, a proximity sensor and a processing unit. The backlight module illuminates with backlight brightness. The ambient light sensor is configured to detect ambient light intensity. The proximity sensor is configured to detect an object. The processing unit is configured to activate the proximity sensor when the ambient light intensity detected by the ambient light sensor is lower than a predetermined value or decreases more than a predetermined range, and to maintain or reduce the backlight brightness according to a detection result of the proximity sensor. There is further provided an automatic detection method.

    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.
