Abstract
An optical apparatus is disclosed, which includes a vibration detection unit which detects vibrations, a signal processing unit which performs signal processing for the vibration detection signal output from the vibration detection unit, a vibration correction unit which corrects an image movement caused by the vibration, on the basis of the drive signal output from the signal processing unit, and a controller which controls the drive of the vibration correction unit. The controller corrects the drive signal from the signal processing unit by using a predetermined correction value corresponding to the driven state of the vibration correction unit, and controls drive of the vibration correction unit by using the corrected drive signal.
