Abstract: A camera module according to an embodiment of the present invention comprises: a light emitting unit for outputting an optical signal to an object; and a light receiving unit for receiving a reflected light obtained after the optical signal is reflected by the object, wherein the light receiving unit comprises: a sensor for receiving the reflected light; a filter for transmitting the reflected light in a specific wavelength band; a driving unit for tilting the filter; and a driving circuit for driving the driving unit, and the filter is sequentially tilted from a reference state, in which the filter is not tilted, to a first to a third tilted state in which the filter is tilted in different directions, so as to allow the sensor to receive the reflected light.
