ABSTRACT:
A position sensing device is provided which can include a first sensing unit for outputting a detection signal periodically changing in accordance with the movement of an object, a second sensing unit for sensing a reference position of the object, and an arithmetic unit for determining position data corresponding to the position of the object based on the detection signals, where the position sensing device can determine the relative position of a lens unit.
