Abstract
A lens apparatus supported by a support member, includes a correction lens for correcting an image blur, a correction lens driving portion for driving the correction lens, a vibration detection portion for detecting vibration of the lens apparatus, and a driving signal calculation unit for calculating a driving signal used for driving the correction lens. The driving signal calculation unit includes a detected vibration calculation portion for calculating a vibration signal based on an output from the vibration detection portion, a panning/tilting component calculation portion for calculating a pan/tilt operation signal based on pan/tilt operation information input from the support member, and a subtraction portion for subtracting the pan/tilt operation signal from the vibration signal. The correction lens driving portion drives the correction lens based on an output from the subtraction portion.
