Abstract
A camera module includes a lens barrel configured to be movable; a detection target disposed on one side of the lens barrel; an integrated coil and a sensing coil facing the detection target and disposed in a direction perpendicular to a direction of movement of the lens barrel; a driver configured to apply a driving signal to the integrated coil; and a position detector configured to detect a position of the lens barrel according to an inductance of the integrated coil and an inductance of the sensing coil, wherein a width of the integrated coil in the direction perpendicular to the direction of movement of the lens barrel and a width of the sensing coil in the direction perpendicular to the direction of movement of the lens barrel change in the direction of movement of the lens barrel.
