Abstract:
An apparatus and a method of controlling the apparatus are provided that can realize high-accuracy correction of image shake due to shift shake. Rotation radiuses at a plurality of frequencies among the frequency components of the shift shake are obtained. Correction amount is determined based on a result of assigning a respective weight to the rotation radius at each of the plurality of the frequencies based on information regarding at least one of an angular velocity and acceleration.
