摘要： A lens driving mechanism is disclosed which can achieve miniaturization of the mechanism by simplification and enhancement of the reliability in position control of a movable block. The lens driving mechanism includes a piezoelectric element deformed when energized for functioning as a driving section for applying driving force to the movable block, a restriction section for restricting the movement of the movable block in the predetermined direction, and a detection section for detecting a predetermined amount regarding the piezoelectric element. The initial position of the movable block is set as a position at an extremity of the movement of the movable block within a movable range based on an inflection point of the predetermined amount detected by the detection section when the movable block moved by the deformation of the piezoelectric element is restricted by the restriction section.

摘要： Disclosed herein is a lens driving mechanism which can achieve simplification of the mechanism and provision of appropriate control relating to correction against a shake. The lens driving mechanism includes a piezoelectric element deformed when energized for applying driving force to the movable block, and a charge amount sensor for detecting the amount of charge accumulated in the piezoelectric element. The amount of electric current to be supplied to the piezoelectric element is determined based on external force, acting upon the movable block, estimated based on a difference between the amount of charge injected into or discharged from the piezoelectric element and the amount of charge accumulated in the piezoelectric element and detected by the charge amount sensor when the movable block is moved in the direction perpendicular to the optical axis.
