20110050982 | LENS BARREL AND IMAGING DEVICE - A lens barrel includes a focusing lens, a driver, and a controller. The focusing lens changes a state of focus by moving in the direction of an optical axis. The focusing lens is subject to a load which is dependent upon the position of the focusing lens along the optical axis. The driver is coupled to the focusing lens and produces a driving force to move the focusing lens along the optical axis at a predetermined speed. The controller is coupled to the driver to adjust the driving speed of the driver relative to the position of the focusing lens. | 03-03-2011 |
