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: Disclosed are a portable electronic device and an operation method thereof. The portable electronic device comprises a body, a barcode detector and a barcode decoder. In the barcode detector, a first image capturing module continually captures a barcode image when the portable electronic device is operating in the resting mode, a first buffering module temporarily stores the captured barcode image, and a first image processing module processes the stored barcode stored and counts a number of times when the barcode image has a predetermined pattern feature. When the number of times reaches to a threshold number, the barcode decoder is turned on to capture and decode the barcode image, and the barcode detector is switched to operate in a power-saving mode.
