Claim:
1. An image stabilization apparatus comprising: a first optical correction unit that has a first correction member and optically corrects an image blur by moving the first correction member in a direction different from an optical axis; a second optical correction unit that has a second correction member and optically corrects the image blur by moving the second correction member in a direction different from the optical axis, the second correction member being arranged in a position different from the first correction member in the optical axis direction; and at least one processor configured to perform the operations of the following units: a first restriction unit configured to set a first restriction which restricts a driving range of the first optical correction unit to a shake signal detected by a shake detection unit; a 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; a 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; a change unit configured to change a restriction value of the first restriction unit and a restriction value of the second restriction unit; and a control unit configured to control the first optical correction unit using the shake signal to which the first restriction has been set and controlling the second optical correction unit using the shake signal to which the second restriction has been set.
