Abstract: The present disclosure provides an anti-shake mechanism of a curved camera device. The camera device is an optical system including a reflecting member having a reflecting surface that bends an optical axis and is configured to perform a hand-shake correction by rotating the reflecting member. The reflecting member is disposed between a camera lens group and a camera element in such a manner that the reflecting member rotates about rotation axes, one of the rotation axes being perpendicular to a plane defined by an optical axis of the camera lens group and an optical axis reflected by the reflecting member, and the other one of the rotation axes being parallel with the reflected optical axis or parallel with the optical axis of the camera lens group.

Abstract: The present disclosure provides an anti-shake mechanism of a curved camera device. The camera device is an optical system including a reflecting member having a reflecting surface that bends an optical axis and is configured to perform a hand-shake correction by rotating the reflecting member. The reflecting member is arranged to be closer to an object side than a camera lens group. When a first rotation axis is set as an axis perpendicular to a plane defined by an optical axis of the camera lens group and an object-side optical axis reflected by the reflecting member and a second rotation axis is set as an axis parallel with the reflected object-side optical axis, the reflecting member is caused to rotate about the first rotation axis and the second rotation axis.

Image shake around an axis perpendicular to a plane formed by a first optical axis (O1) and a second optical axis (O2) is corrected by rotation of the reflection member, and image shake around the first optical axis (O1) is corrected by movement of a first set of lenses immediately following the reflection member.

Image shake of an axis that is parallel to the reflected optical axis of the object side is corrected by moving the imaging lens sets including the zoom optical system as a whole along a direction perpendicular to the optical axis of the imaging lens sets.
