1. A sensor module comprising:
an event-driven vision sensor that includes a sensor array having a sensor that generates an event signal when the sensor detects a change in intensity of incident light;
an actuator connected to the sensor array and configured to displace the sensor array in a predetermined direction in order to cause an appearance of movement by at least one object and to invoke the change in intensity of incident light and the event signal even when the at least one object is stationary; and
a control unit that receives the event signal and detects a subject from the event signal, transmits a control signal for displacing the sensor array in the predetermined direction to the actuator, and detects the subject from the event signal generated after the control signal is transmitted.
