Abstract
A device for compensating movement of an image formed by an optical system comprises first and second sensing units arranged at different positions along an optical axis of the optical system to sense an acceleration of the device, a compensation optical system arranged on a light path of the optical system and supported movably relative to the device to compensate for the movement of the image driver for driving the compensation optical system, and a calculation unit for calculating a displacement of the compensation optical system based on the outputs of the first and second acceleration sensing units and supplying displacement information to the driver.
