Patent ID: 8253811

Claim:
An image blur correcting unit that allows the optical axis of a lens system to coincide with the center of an imager in order to correct an image blur, the unit comprising: a stationary member; a holder member holding either one of the elements of the lens system or the imager, the holder member moving relative to the stationary member in a first direction and a second direction, and the first and second directions being orthogonal to each other in a plane orthogonal to the optical axis; first guide means for guiding the movement of the holder member in the first direction; second guide means for guiding the movement of the holder member in the second direction; and driving means for moving the holder member in the first and second directions, wherein the one of the elements of the lens system or the imager is disposed outside an area surrounded by the first and second guide means when the first and second guide means are viewed from the optical axis, and the area surrounded by the first and second guide means is laterally displaced, with respect to the optical axis, relative to another area surrounded by the one of the elements of the lens system or the imager.
