1. A control apparatus comprising at least one processor or circuit configured to execute a plurality of tasks, including:
a first acquiring task configured to acquire first information on an image shift sensitivity to a tilt of an imaging optical system corresponding to an image point position of the imaging optical system, the first information indicating an image point moving amount at an image plane of the imaging optical system caused by the tilt, and including an influence of a distortion of the imaging optical system; and
a second acquiring task configured to acquire an image-stabilization driving amount that is used for an image stabilization by an image stabilizer configured to provide the image stabilization,
wherein the second acquiring task acquires the image-stabilization driving amount corresponding to a predetermined image point position using the first information corresponding to the predetermined image point position, and
wherein the image-stabilization driving amount corresponding to a first image point position is different from the image-stabilization driving amount corresponding to a second image point position, which is different from the first image point.
