Patent ID: 8275249

Claim:
A blur correction device, comprising: a first member that is driven along an optical axis of an optical system; a blur correction unit that is held by the first member and that includes a second member and a first drive unit driving the second member within a plane perpendicular to the optical axis of the optical system relative to the first member so as to correct an image blur, the second member including: a blur correction optical system that corrects the image blur when the second member is driven within the plane perpendicular to the optical axis of the optical system during a photographing state; a position fix member that holds the blur correction optical system at a predetermined position by contacting the blur correction optical system during the photographing state; and a second drive unit that supports the blur correction optical system and that is mounted on the second member so that the blur correction optical system is driven between a retreat position and the predetermined position relative to the second member, the blur correction optical system being retreated into the retreat position during a stored state and being held at the predetermined position by the position fix member during the photographing state; a recording unit that records a reference position regarding the second member on that plane perpendicular to an optical axis; and a control unit that controls a position of the second member within the plane perpendicular to the optical axis of the optical system relative to the first member by the first drive unit during the photographing state so that the reference position coincides with a center position of the blur correction optical system, wherein when the second member is at the reference position, the blur correction optical system contacting the position fix member and the optical system other than the blur correction optical system are aligned.
