Abstract
Official abstract text for this publication.
An optical apparatus includes a blurring detection unit configured to detect image blurring applied to the optical apparatus; and a motion vector calculation unit configured to calculate a motion vector among a plurality of images shot by the optical apparatus. Image blurring is corrected in accordance with a signal obtained from blurring detected by the blurring detection unit; the motion vector is calculated using a correction result of the image blurring; and the image blurring is further corrected using the calculated motion vector.
