1. A motion compensation device suitable for a camera comprising:

  • a detection unit detecting an amount of motion about a camera;

    a photographic preparatory operation commencement instruction unit generating a first instruction to commence photographic preparatory operations including the commencement of the detection unit;

    an exposure commencement instruction unit generating a second instruction to commence an exposure operation;

    a motion compensation unit to drive an optical system of the camera to inhibit image blurring on a focal plane based on the amount of motion detected by the detection unit;

    a stabilization time judgment unit judging whether a photographic preparatory time from when the photographic preparatory operation instruction unit generates the first instruction until the exposure commencement instruction unit generates the second instruction is longer or shorter than a predetermined amount of time, the predetermined time being long enough to allow the operation of the detection unit to become stable; and

    a control unit controlling the motion compensation unit so as to inhibit operation of the motion compensation unit after the exposure operation commences when the stabilization time judgment unit judges that photographic preparatory time is shorter than the predetermined time.
