Abstract
An optical image stabilizer includes an optical system including at least one image shake counteracting optical element movable in a plane orthogonal to an optical axis; at least one stepping motor for moving the image shake counteracting optical element in the plane; at least one shake velocity sensor which senses the speed of shake applied to the optical system; and a controller which calculates the number of driving pulses for the stepping motor based on shake speed information output from the shake velocity sensor, and drives the stepping motor so that the image shake counteracting optical element moves in the plane to counteract image shake on an imaging surface of the optical system. The controller changes power supplied to the stepping motor in accordance with the shake speed information when driving the stepping motor.
