Title:
ANTIVIBRATION DEVICE AND METHOD, AND IMAGING SYSTEM
Document Type and Number:
Japanese Patent JP2021060525
Kind Code:
A
Abstract:
To perform stable parallel shake correction during photography.SOLUTION: An antivibration device has: operation means that inputs an angular velocity signal representing an angular velocity detected by angular velocity detection means and a plurality of acceleration signals representing accelerations detected by a plurality of acceleration detection means provided separate from each other, and determines a plurality of distances from the center of rotation of shake to the plurality of acceleration detection means based on the angular velocity signal and the plurality of acceleration signals; shake detection means that performs weighted addition according to the plurality of distances based on a result of comparison between the plurality of distances, determines the radius of rotation of the shake based on the distances for which the weighted addition is performed and the weight used for the weighted addition, and determines a shake amount of the shake from the radius of rotation and the angular velocity signal; and calculation means that determines the amount of drive of shake correction means for correcting shake based on the shake amount.SELECTED DRAWING: Figure 1
