Summary:PROBLEM TO BE SOLVED: To provide an imaging device that enables AF processing to be performed at high speed and with high accuracy.SOLUTION: The imaging device 1 comprises a drive control part 304 that, when it is determined by a focus sensitivity determination part 301 that focus sensitivity is equal to or less than a prescribed value, and it is determined by the focus sensitivity determination part 301 that the focus sensitivity is not equal to less than the prescribed value, drives a piezoelectric element 102, and controls to cause a movable frame 100 to move to an in-focus position. 【課題】ＡＦ処理を高速かつ高精度で行うことができる撮像装置を提供する。【解決手段】撮像装置１は、フォーカス感度判定部３０１によってフォーカス感度が所定値以下であると判定された場合、フォーカス感度判定部３０１によってＦＣ感度が所定値以下でないと判定した場合、圧電素子１０２を駆動して可動枠１００を合焦点位置へ移動させる制御を行う駆動制御部３０４と、を備える。【選択図】図８
