At least one exemplary embodiment is directed to an optical element
driving apparatus which includes a first actuator configured to drive an
optical element in accordance with a deformation target value, a sensor
arranged to measure a position and an orientation of the optical element,
a second actuator configured to drive the optical element in accordance
with position and orientation target values and an output of the sensor,
and a correcting unit configured to correct a measurement error of the
sensor caused by deformation of the optical element.
