Abstract:
A camera module according to one embodiment of the present invention comprises: a lighting unit for outputting an output light signal emitted at an object; a lens unit including an infrared (IR) filter and at least one sheet of a lens arranged on the IR filter, and condensing an input light signal reflected from the object; a tilting unit for shifting the optical path of the input light signal by controlling the tilt of the IR filter; an image sensor unit for generating an electric signal from the input light signal condensed by the lens unit and shifted by the tilting unit; an image control unit for extracting depth information of the object by using a phase difference between the output light signal and the input light signal received by the image sensor unit; and a detection unit for detecting tilt information of the IR filter and providing the tilt information of the IR filter to the image control unit.
