Abstract
A detecting method is provided for detecting motion direction of a portable electronic device. The portable electronic device senses a plurality of continuous images in time sequence via an image sense unit. The differences among the plurality of images are analyzed by a process unit. Consequently the process unit determines the motion direction of the portable electronic device, generates motion data based on the differences, and sends a control signal corresponding to the motion direction of the device and the motion data.
