Abstract
An optical device includes a base member, an image-stabilizing lens, a lens holding member mounted to the base member and configured to hold the image-stabilizing lens, a driving unit configured to drive the lens holding member in a direction orthogonal to an optical axis, a plurality of elastic members fixed between the base member and the lens holding member, a vibration detecting unit configured to detect vibration, and a control circuit configured to control the position of the lens holding member on the basis of vibration information from the vibration detecting unit. The center position of the driving range of the image-stabilizing lens is controlled on the basis of vibration information obtained during a predetermined period between the time when a first trigger signal is input and the time when a second trigger signal is input.
