1. An image stabilization apparatus comprising at least one hardware processor or circuit configured to perform the operations of the following units:

  • a rotational shake calculation unit configured to calculate a rotational shake amount based on an output of a rotational shake detection unit;

    a translational shake calculation unit configured to calculate a translational shake amount using a subtraction result value acquired by subtracting the rotational shake amount output by said rotational shake calculation unit from shake amount including a rotational shake amount and a translational shake amount output by a motion vector detector;

    a component calculation unit configured to calculate a first translation component and a perspective component using the rotational shake amount calculated by the rotational shake calculation unit and calculate a second translation component using the translational shake amount calculated using the subtraction result value; and

    a correction amount calculation unit configured to calculate, based on the first translation component, the perspective component and the second translation component, a correction amount for correcting image blurring of an image.
