First Claim
1. A shake detection apparatus, characterized by comprising:
- shake detection means for outputting an electric signal according to shake applied to the shake detection apparatus;
a plurality of shake correction amount deriving means having integration means for integrating the electric signal output from the shake detection means and deriving shake correction amounts for correcting shake shown by the electric signal output from the shake detection means; and
output means for selecting any of the plurality of shake correction amount deriving means and outputting the shake correction amount derived by the selected shake correction amount deriving means as a shake correction amount used to correct the shake applied to the shake detection apparatus.

Abstract
The correction amounts of respective correction units 37 of first and second shake correction amount deriving units 38, 39 are alternately employed in every short period composed of a time shorter than a period up to a timing at which it is contemplated that the output from a first HPF 31 is approximately stabilized after a switch S1 is turned on, and the signals of shake correction amounts, which are obtained by subjecting the outputs from first integration units 35 to a correction of the correction amounts, are alternately employed as drive signals to be output to the X-axis and Y-axis actuators 27, 28. With this arrangement, a shake correction amount deriving unit, which is operated later than a shake correction amount deriving unit operated just before it, can derive a shake correction amount based on a state in which a first HPF 31 has a smaller output error.
