Abstract: There is provided a treadmill capable of performing the fall detection. The treadmill includes a light sensor and a processor. The light sensor acquires an image frame toward an operation space. The processor performs the occupancy detection on the image frame using face detection and human detection. Upon not detecting the operation space being occupied by any user during a running state of the treadmill, the processor deactivates the treadmill and raises a fall alarm.

Abstract: There is provided a displacement detection device including an image sensor, a light source, a light control unit and a processing unit. The image sensor captures image frames at a sampling frequency. The light source provides, in a speed mode, light for the image sensor in capturing the image frames. The light control unit controls the light source with the speed mode to turn on at a lighting frequency or to turn off serially. The processing unit calculates a displacement according to the image frames captured when the light source turns on to be served as an estimated displacement for an interval during which the light source turns off.
