Abstract:
An equipment with shake correction apparatus comprising at least one set of an angular velocity sensor for sensing an angular velocity due to a shake by using Coriolis force, a filter including a low-pass filter or a band-pass filter for filtering an output signal of the angular velocity sensor, and a driving device for driving a correction lens system for canceling the shake corresponding to the angular velocity; and satisfying a relationfc<.vertline.m.multidot.fg-n.multidot.fp.vertline.wherein the symbol fg designates an excitation frequency of an excitation signal for excitingly vibrating an angular velocity detecting portion of the angular velocity sensor; the symbol fp designates a fundamental frequency of a mechanical vibration generated by driving of the driving device; the symbol fc designates a cutoff frequency of the low-pass filter or a cutoff frequency of the band-pass filter in high frequency; symbols m and n respectively designate optional positive integers equal to or larger than one, and when the symbol m or n is equal to or larger than two, it designates a harmonic of the frequency fg or fp.
