Abstract
A camera module includes a first position sensor configured to detect a position of a lens barrel in a first direction and including a 1-1-th sensing coil and a 1-2-th sensing coil having respective inductances that change as the lens barrel moves in the first direction; and a second position sensor including a second sensing coil having an inductance that changes as the lens barrel moves in a second direction, and a third sensing coil having an inductance that changes as the lens barrel moves in a third direction, wherein the second position sensor is configured to detect a position of the lens barrel in the second direction and a position of the lens barrel in the third direction by adding or subtracting a reference inductance to or from the inductance of the second sensing coil and the inductance of the third sensing coil.
