Abstract
A sensing unit of a camera module includes a detection target provided on a side surface of a lens module, one or more sensing coils disposed to face the detection target, and a calculator. The calculator may determine a displacement of the detection target translated in any of an optical axis direction, a first direction perpendicular to the optical axis direction, and a second direction perpendicular to the optical axis direction, based on inductances of the one or more sensing coils.
