IMAGE STABILIZATION APPARATUS AND METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM

摘要

An image stabilization apparatus comprises first optical correction unit configured to optically correct an image blur, second optical correction unit configured to optically correct the image blur, first restriction unit configured to set a first restriction which restricts a driving range of the first optical correction unit, subtraction unit configured to obtain a result of subtraction by subtracting the shake signal to which the first restriction has been set from the shake signal detected by the shake detection unit, second restriction unit configured to set a second restriction which restricts a driving range of the second optical correction unit to the result of subtraction, change unit configured to change a restriction values, and control unit configured to control the first and second optical correction units.

1. An image stabilization apparatus comprising:
first optical correction unit configured to optically correct an image blur by moving in a direction different from an optical axis; second optical correction unit, arranged in a position different from said first optical correction unit in the optical axis direction, configured to optically correct the image blur by moving in the direction different from the optical axis; first restriction unit configured to set a first restriction which restricts a driving range of said first optical correction unit to a shake signal detected by shake detection unit; subtraction unit configured to obtain a result of subtraction by subtracting the shake signal to which the first restriction has been set from the shake signal detected by the shake detection unit; second restriction unit configured to set a second restriction which restricts a driving range of said second optical correction unit to the result of subtraction; change unit configured to change a restriction value of said first restriction unit and a restriction value of said second restriction unit; and control unit configured to control said first optical correction unit using the shake signal to which the first restriction has been set and controlling said second optical correction unit using the shake signal to which the second restriction has been set.
