Claim:
1. An image stabilization apparatus comprising: a first filter configured to receive an output signal from a vibration detector and to gradually decrease a frequency component lower than a first cutoff frequency in the output signal; a second filter configured to receive the output signal and to gradually decrease a frequency component lower than a second cutoff frequency in the output signal; a first cutoff frequency switch configured to gradually decrease the first cutoff frequency in the first filter to a third cutoff frequency lower than the first cutoff frequency; a second cutoff frequency switch configured to gradually decrease the second cutoff frequency in the second filter to a fourth cutoff frequency lower than the second cutoff frequency; and a signal selector configured to select as a correction signal for an image stabilization a signal obtained from an output of one of the first filter and the second filter which has a higher cutoff frequency, and thereafter to select as the correction signal a signal obtained from an output of the other of the first filter and the second filter which has a lower cutoff frequency, when the first filter has the third cutoff frequency or the second filter has the fourth cutoff frequency.
