Claim 0:
1. A camera module comprising:
a light output unit configured to output an optical signal to an object;
an optical unit configured to pass the optical signal reflected from the object;
a sensor configured to receive the optical signal passed by the optical unit; and
a control unit configured to acquire depth information of the object using the optical signal received by the sensor,
wherein the sensor includes an effective area in which a light receiving element is disposed and an ineffective area other than the effective area,
the sensor includes a first row region, in which the effective area and the ineffective area are alternately disposed in a row direction, and a second row region, in which the effective area and the ineffective area are alternately disposed in the row direction and the effective area is disposed at a position not overlapping the effective area of the first row region in a column direction,
light that reaches the effective area of the first row region is controlled by first shifting control to reach the ineffective area of the first row region or the ineffective area of the second row region, and
light that reaches the effective area of the second row region is controlled by the first shifting control to reach the ineffective area of the second row region or the ineffective area of the first row region,
wherein light that reaches the ineffective area of the first row region is controlled by second shifting control to shift toward the ineffective area of the second row region that is adjacent to the ineffective area of the first row region,
wherein the light that reaches the effective area of the first row region is controlled by second shifting control to shift toward the effective area of the second row region that is adjacent to the effective area of the first row region.
