Title:
SHAKE COMPENSATION DEVICE, OPTICAL DEVICE, AND CAMERA
Document Type and Number:
WIPO Patent Application WO/2021/108949
Kind Code:
A1
Abstract:
A shake compensation device, an optical device (100), and a camera (1000). The shake compensation device comprises a stator group (40, 80) and a mover group (60). The stator group (40, 80) is used for driving the mover group (60) to move. The mover group (60) is fixedly connected to an imaging unit (30). The stator group (40, 80) and the mover group (60) are disposed on the side of the imaging unit (30) facing away from an imaging surface (321). The manner of driving the mover group (60) to move by the stator group (40, 80) can drive the imaging unit (30) to move, and both the stator group (40, 80) and the mover group (60) are disposed on the side of the imaging unit (30) facing away from an imaging surface (321), that is, there is no need to drive the imaging unit (30) to move on the peripheral side surface of the imaging unit (30), and the size of the periphery of the imaging unit (30) can be reduced. The shake compensation device is adapted to the shape of the imaging unit (30) and is thus stacked thereon, and also better facilitates the structural compact design of the optical device (100) and the camera (1000), and is small in size and easy to carry and use.
