Abstract:
1. A stabilization control apparatus comprising: a correction unit configured to compensate shake of the apparatus; a first detection unit configured to detect a rotational shake; a second detection unit configured to detect a translational shake; a first extractor configured to extract a signal in a plurality of different predetermined frequency bands based on the detection result of the rotational shake, wherein the first extractor configured to extract a signal with a frequency band narrower than a frequency band of shake occurring due to the shake; a second extractor configured to extract a signal in a plurality of different predetermined frequency bands based on the detection result of the translational shake, wherein the second extractor configured to extract a signal with a frequency band narrower than the frequency band of shake occurring due to the shake; a calculation unit configured to calculate correction values for each of the plurality of different frequency bands based on the signals extracted by the first extractor and the second extractor; a selection unit configured to select a correction value among the plurality of different frequency bands; an output correction unit configured to correct the output of the first shake detection unit based on the correction value selected by the selection unit and output as a translational shake amount; and a driving unit configured to drive the shake correction unit based on the translational shake amount.
