Abstract:
According to an embodiment of the present invention, disclosed is a camera module comprising: a light output unit for outputting an optical signal to an object; a sensor for receiving an optical signal reflected from the object; and a control unit for acquiring distance information about the object by using the phase difference of the received optical signal, wherein the sensor includes a non-extraction area from which the phase different is not extracted and an extraction area from which the phase difference is extracted and the control unit stops timing control for the received optical signal in the non-extraction area.
