A signal processing method for an optical trace-detecting module is adapted to perform signal processing between a hardware device having an optical trace-detecting module and a computer device. After a hardware device performs signal connection with a computer device, a fingerprint recognition start-up is implemented by an optical trace-detecting module of the hardware device. Continuous image detection is then performed for displacement control. The presence of the hardware device is confirmed by a start-up procedure of the computer device. A single fingerprint image is picked up by the optical trace-detecting module of the hardware device so as to perform start-up ID recognition. After that, a plurality of frames of object images is continuously picked up by the optical trace-detecting module, and then converted into a displacement signal to be transmitted to the computer device, so as to control a window interface.
