An image blur compensation device for use with an image capture device including an imaging optical system and an imaging unit which converts a subject image captured on a light receiving surface thereof through the imaging optical system into an image signal. The compensation device includes a variable mirror which is provided on the optical axis of the imaging optical system and which has a displaceable reflective surface and an electrode to control the displacement of the reflective surface. A drive unit supplies the electrode with a drive signal to displace the reflective surface. And a compensation unit produces correction information to correct the drive signal.
