To suppress the increase of power consumption by shortening the time from a start-up time to the completion of initialization processing, in a drive device including a movable part and a fixed part.SOLUTION: An imaging apparatus 101 includes: a movable part 102 including an imaging optical system and an imaging part; and a fixed part 103. An angular velocity meter 106 for detecting the angular velocity of a vibration is provided in the fixed part 103. A tilt rotation unit 104 rotates the movable part 102 in a tilting direction and a pan rotation unit 105 rotates the movable part 102 in a panning direction. When performing the initialization processing of the movable part 102 at the time of start, a control part 213 determines a drive direction of the initialization of the pan rotation unit 105 on the basis of the vibration detected by the angular velocity meter 106, when performing the drive control of the tilt rotation unit 104. The detection processing of an original position (reset position) is performed on the basis of the determined drive direction.SELECTED DRAWING: Figure 2 【課題】可動部と固定部を備える駆動装置において、起動時点から初期化処理が終了するまでの時間を短縮し、消費電力の増加を抑制する。【解決手段】撮像装置１０１は、撮像光学系および撮像部を備える可動部１０２と、固定部１０３を備える。固定部１０３には振動の角速度を検出する角速度計１０６が設けられている。チルト回転ユニット１０４は可動部１０２をチルティング方向に回転させ、パン回転ユニット１０５は可動部１０２をパンニング方向に回転させる。制御部２１３は起動時に可動部１０２の初期化処理を行う際、チルト回転ユニット１０４の駆動制御時に角速度計１０６が検出した振動に基づいてパン回転ユニット１０５の初期化の駆動方向を決定する。決定された駆動方向に基づいて原点位置（リセット位置）の検出処理が行われる。【選択図】 図２
