摘要:
An image entering from the left side of the figure passes through a correcting lens unit, and forms an image on an image pickup device on the right side of the figure. The correcting lens unit includes a cylindrical outer frame and a lens arranged therein, and at coupling points, coupled to one end of each of electrostrictive coils and suspended thereby. Electrostrictive coils strain in response to voltages applied from a voltage applying unit, causing displacement of electrostrictive coils. The displacement is transmitted to correcting lens unit through the coupling points, and therefore, in accordance with the displacement from electrostrictive coils, position and/or direction of correcting lens unit changes.
