<p>PROBLEM TO BE SOLVED: To effectively correct image blurring by driving a correction means holding an optical element for vibration-proofing based on signals from 1st and 2nd sake detection means mutually detecting the shake in a different direction. SOLUTION: An optical holding means holding the optical element and driving it in a direction orthogonal to an optical axis is attached to a supporting means fixed in a lens barrel so that it can be driven. Then, a 1st shake detection means detecting the shake in one direction and a 2nd shake detection means detecting the shake in the other direction and having different detection characteristics from the 1st shake detection means are provided at a part of the lens barrel. Based on the signals from the 1st and the 2nd shake detection means, the optical holding means is driven to correct the image blurring. A shake correction system 102 is composed of a shake sensor 106 detecting the shake, a position sensor 107 for detecting the displacement of a correction lens, and a shake correction driving system 108 which drives the correction lens according to a control signal calculated by a lens microcomputer 101 based on output from the sensors 106 and 107 so as to correct the image blurring.</p> |
