Abstract
In a shake correctable apparatus, beat signals generated by interference of a mechanical vibration having a frequency fg due to a excitation of an angular velocity sensing portion of an angular velocity sensor and a mechanical vibration having a frequency fp due to a driving of a driving device are removed from an output signal of the angular velocity sensor by a filtering operation of a low-pass filter or a band-pass filter. The frequencies fg and fp have a relation of fc<.vertline.m.multidot.fg-n.multidot.fp.vertline. with respect to a cutoff frequency fc of the filter in high frequency side.
