Patent ID: 7512327

Claim:
An image capturing device having a blurring correction function, comprising: an imaging optical system; an imaging unit which converts an object image formed by the imaging optical system into an electric signal; an image processing circuit which generates image data from the electric signal of the imaging unit; a recording circuit which records the image data in a recording medium; a support member which displaceably supports the imaging unit along a plane which is perpendicular to an optical axis of the imaging optical system; a position detecting sensor for detecting a position of the imaging unit; an actuator connected to the support member, including an electromechanical conversion unit as a driving source, and having a frictionally connected section in a conversion mechanism for converting an expanding or contracting operation of the electromechanical conversion unit into a driving force to drive the support member; a vibration detecting sensor which detects a vibration; a control circuit which controls the actuator depending on outputs of the vibration detecting sensor and the position detecting sensor so as to prevent the object image from being deteriorated by the vibration and which calculates a correction target position of the imaging unit in a predetermined period based on the outputs of the vibration detecting sensor and the position detecting sensor in order to control the actuator; and an impact detecting section which detects an impact at least one of applied to and generated within the image capturing device, wherein the control circuit regards a present position of the imaging unit detected by the position detecting sensor as the correction target position, when the impact detecting section detects the impact.
