Abstract:
According to an embodiment of the present invention, disclosed is a camera module comprising: an optical output unit for outputting an optical signal to an object; an optical unit for transmitting the optical signal reflected from the object; a sensor for receiving the optical signal transmitted through the optical unit; and a control unit for acquiring the depth map of the object by using the optical signal received by the sensor, wherein the sensor includes an effective area in which a light receiving element is arranged and a non-effective area excluding the effective area, and includes a first row area in which the effective area and the non-effective area are alternately arranged in a row direction, and a second row area in which the effective area and the non-effective area are alternately arranged in the row direction, and in which the effective area is arranged in a column direction at a position not overlapping with the effective area of the first row area, light reaching the effective area of the first row area is controlled by means of first shifting control so as to reach the non-effective area of the first row area or the non-effective area of the second row area, and light reaching the effective area of the second row area is controlled by means of the first shifting control so as to reach the non-effective area of the second row area or the non-effective area of the first row area.
