<p>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.</p> |
