ABSTRACT:
An image stabilization apparatus comprises a detection unit that detects camera shake in first and second directions orthogonal to each other, first and second filter units that cut off a low frequency component of an output from the detection unit, a calculation unit that calculates correction amounts for correcting camera shake in the first and second directions based on outputs from the first and second filter units, a control unit that controls cutoff frequencies of the first and second filter units based on the first and second correction amounts, wherein the larger the correction amount the higher the cutoff frequency, a determination unit that determines whether the first and second correction amounts exceed predetermined values, and a correction unit that corrects camera shake based on the calculated correction amounts. The control unit controls the cutoff frequencies of the second/first filter units based on the first/second correction amounts in a case in which the first/second correction amounts exceed the predetermined values.
