ABSTRACT:
This specification discloses an image stabilizing apparatus of high accuracy which includes a photo-taking lens having a first lens unit movable along the optic axis thereof to vary the focal length thereof, a second lens unit movable along the optic axis thereof to effect focus adjustment, and an optical unit for compensating for the vibration of an image, first and second detectors for detecting the lens positions of the first and second lens units, a third detector for detecting the vibration of the photo-taking lens, and a calculator for calculating the amount of compensation of the optical unit on the basis of the detection signals of the first, second and third detectors and in which the optical unit is operated to thereby ensure a good follow-up property relative to image vibration.
