Image capturing apparatus

An image capturing apparatus comprising:

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