Patent ID: 8659671

Claim:
An optical apparatus having a recording mode for recording a motion picture and a recording mode for recording a still picture, said optical apparatus comprising: an optical element; a motor that includes a rotor having a magnet, and a stator having a coil configured to provide a rotational force to the magnet, the motor being configured to drive the optical element; a position sensor configured to detect a rotational position of the rotor; a driving circuit configured to select, in accordance with the recording mode, first driving configured to switch an electrization to the coil in the motor in accordance with a determined time interval, or second driving configured to switch an electrization to the coil in the motor in accordance with an output of the position sensor; and a controller configured to select, via the driving circuit, the first driving when a target driving amount as a difference between a target position to which the optical element is driven and the current position is smaller than a threshold, or the second driving when the target driving amount is equal to or larger than the threshold, wherein a value to which the threshold is set depends on whether the recording mode is a recording mode for recording a motion picture or a recording mode for recording a still picture.
