Abstract
A motion compensation device includes 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, and a photographic operation commencement instruction unit generating a second instruction to commence photographic operations, a motion compensation unit to drive a photographic optical system of the camera to inhibit image blurring on a focal plane based on the amount of motion detected by the detection unit, and a stabilization time determination unit determining whether the photographic preparatory time from when the photographic preparatory operation instruction unit generates the first instruction until the photographic operation commencement instruction unit generates the second instruction is longer or shorter than a predetermined amount of time. The predetermined amount of time is long enough to allow the operation of the detection unit to become stable. Also provided is a control unit that controls the motion compensation unit so as to inhibit operation thereof when the stabilization time judgment unit judges that photographic preparatory time is shorter than the predetermined time. Finally, the motion compensation device inhibits motion compensation after commencement of an exposure period in order to conserve power in an imaging unit that embodies the invention.
