摘要:
Provide a camera capable of effectively suppressing image blurring even when high frequency vibrations are imposed. The present invention is a camera for capturing moving images furnished with an image-blur prevention function, including an imaging unit (16) for capturing moving picture images and a support frame (12) equipped with a vibration-isolating support mechanism (18) for supporting this imaging unit; the imaging unit has imaging optics (22), an imaging element (20), and an anti-vibration mechanism (24) for stabilizing formed images; assuming Sa(f) denotes the rate in dB of vibration attenuation produced by an anti-vibration mechanism, Sp(f) denotes the rate in dB of vibration attenuation produced by a vibration-isolating support mechanism, So denotes a predetermined target dB rate of attenuation, and 2f0 denotes a frame rate frequency for moving pictures captured by the imaging unit, then at frequencies at or greater than f0, the expression Sa(f)+Sp(f)
