An image capturing apparatus comprises: an image sensor adapted to opto-electronically convert the image of a subject; an optical member placed in front of the image sensor; first and second piezoelectric elements placed at respective ones of both ends of the optical member; first and second driving units adapted to independently vibrate the first and second piezoelectric elements, respectively; a detection unit having first and second detecting piezoelectric elements placed adjacent to the first and second piezoelectric elements, respectively, for detecting vibration of the optical member; and a first control unit adapted to control the first and second driving units and the detection unit so as to vibrate the optical member by vibrating the first piezoelectric element and detect vibration of the optical member using the second detecting piezoelectric element, or vibrate the optical member by vibrating the second piezoelectric element and detect vibration of the optical member using the first detecting piezoelectric element. |
