Claim Text:
1. An optical device comprising: an image blur compensation unit which compensates a blur in an image formed by an imaging optical system, the image blur compensation unit being movable in directions not parallel to an optical axis of the imaging optical system; a shake detection unit which detects shake of the optical device; a position detection unit which detects a position of the image blur compensation unit, the position detection unit having a position resolution that is variable; and a driving control unit which calculates a driving target position of the image blur compensation unit based on an output from the shake detection unit and position information of the image blur compensation unit that is detected by the position detection unit, wherein the driving control unit sets a first movable range as a range in which the image blur compensation unit can be driven when video is captured, and sets a second movable range which is narrower than the first movable range as a range in which the image blur compensation unit can be driven when a still image is captured, and wherein the position resolution of the position detection unit when the second movable range is set is greater than the position resolution of the position detection unit when the first movable range is set.
