8 is a diagram illustrating an arrangement of a magnet and a coil of the image stabilization assembly 400 according to an exemplary embodiment.

In one embodiment, the image stabilization assembly 400 electromagnetically interacts with the first and

second magnets

425 and 428, respectively, upon application of an electric current, thereby causing the first and

second magnets

425 and 428, respectively. It may include first and

second coils

441 and 442 provided to move. The first and

second coils

441 and 442 may be disposed at positions capable of interacting with the first and

second magnets

425 and 428 . The first coil 441 may include a first left coil 441a and a first right coil 441b respectively corresponding to the first left magnet 426 and the first right magnet 427 .

In an embodiment, one of the magnets and the coils may be disposed on a fixed structure and the other may be disposed on a moving structure that moves relative to the fixed structure. For example, the coils may be disposed on a printed circuit board (eg, printed circuit board 460 in FIGS. 10A and 10B ) fixed to a housing that is a fixed structure (eg, housing 450 in FIGS. 10A and 10B ). there is. For example, the magnets may be disposed in the magnet holder 421 which is a moving structure. However, the present invention is not necessarily limited thereto, and the positions of the magnets and the coils may be interchanged.

According to an embodiment (not shown), a plurality of second magnets 428 may be configured. For example, the second magnet may include a second left magnet and a second right magnet disposed on the connecting member 424 to be spaced apart from each other in the X-axis direction. The second left magnet and the second right magnet may be spaced apart from each other by the same distance from the optical axis along the -X axis and the X axis direction, respectively.

In another embodiment (not shown), the magnet holder may include a pivot for supporting the magnet holder during tilting. For example, the pivot is formed to extend from the magnet holder toward one side of the printed circuit board (eg, the printed circuit board 460 of FIGS. 10A and 10B ) facing the magnet holder, one side of the printed circuit board during tilting can be supported by

In an embodiment, the image stabilization assembly 400 may include

sensors

443 and 444 for detecting a relative position between magnets and coils disposed to correspond thereto. The

sensors

443 and 444 may include a Hall sensor provided to detect a magnetic field. The

sensors

443 and 444 are between the first sensor 443 for detecting a relative position between the first magnet 425 and the first coil 441 and the second magnet 428 and the second coil 442 . It may include a second sensor 444 for detecting the relative position of the. The

sensors

443 and 444 may be located inside the corresponding

respective coils

441 and 442 . The first sensor 443 may include a first left sensor 443a corresponding to the first left coil 441a and a first right sensor 443b corresponding to the first right coil 441b.

In one embodiment, the first magnet 425 for the yaw tilt and the second magnet 428 for the pitch tilt are physically separated from each other, so it is easy to control the yaw tilt and/or pitch tilt by the magnet and the coil can do.

In an embodiment, since the second magnet 428 for pitch tilt is spaced apart from the first magnet 425 from the tilting center, it may be easy to secure a pitch torque.

In one embodiment, since the first magnet 425 and the second magnet 428 are disposed in one direction (eg, an optical axis direction, a direction substantially parallel to the Y-axis), a height direction (eg, the Z-axis direction) As a result, the dimensions of the image stabilization assembly 400 may be reduced.

In an embodiment, reference positions of the first magnet 425 and the second magnet 428 may be stored in a memory (eg, the memory 130 of FIG. 1 ). When the positions of the first magnet 425 and the second magnet 428 detected by the first sensor 443 and the second sensor 444 are different from the reference position, the first coil ( 441 ) and a current (eg, amount of current, current direction) applied to the second coil 442 may be controlled. For example, when current is applied again in a state in which no current is applied to the first coil 441 and the second coil 442 , the above control is performed to position the magnet holder 421 in its original position. can be

In an embodiment, the sensed values of the first left sensor 443a and the first right sensor 443b may be summed for control. For example, if the magnet holder 421 is rotated about the Z-axis direction by an external force or the like, the distance between the first left coil 441a and the first left magnet 426 and the first right coil ( A distance between 441b) and the first right magnet 427 may be different from each other. Accordingly, the tilting center point may be moved. At this time, if the yaw tilt is implemented around the Z-axis direction, the movement of the center point is not reflected, so the yaw tilt may not be accurately implemented. In order to compensate for such a control error, the sensing values of the first left sensor 443a and the first right sensor 443b may be summed for control. The first left sensor 443a and the first right sensor 443b may be connected in parallel.

In an embodiment, at least one of the first magnet 425 and the second magnet 428 may include a pair of sub-magnets that are symmetrically disposed with respect to the optical axis of the optical unit. For example, the first magnet 425 may include a first left magnet 426 and a first right magnet 427 as sub-magnets. The first left magnet 426 and the first right magnet 427 may be disposed to be spaced apart from each other by the same distance in the -X-axis direction and the X-axis direction with respect to the optical axis (eg, the optical axis O of FIG. 4 ) of the optical unit. there is. In another embodiment (not shown), the second magnet 428 also includes a second left magnet and a second right magnet disposed on the connection member 424 to be spaced apart from each other by the same distance along the -X axis and the X axis direction. can do.

In an embodiment, a coil corresponding to a magnet including a pair of sub-magnets may also include a pair of sub-coils corresponding to a pair of sub-magnets. For example, a first left coil 441a and a first right coil 441b may be provided to correspond to the first left magnet 426 and the first right magnet 427 .

In an embodiment, a sensor corresponding to a magnet including a pair of sub-magnets may also include a pair of sub-sensors corresponding to the pair of sub-magnets. For example, a first left sensor 443a and a first right sensor 443b may be provided to correspond to the first left magnet 426 and the first right magnet 427 . The sensed values sensed by the pair of sub-sensors may be summed to detect a relative position. For example, the value sensed by the first left sensor 443a and the value sensed by the first right sensor 443b may be summed to compensate for a control error caused by the movement of the driving center point.

Hereinafter, the first right magnet 427 and the first right coil 441b corresponding thereto will be described as an example. The remaining magnets and their corresponding coils may operate substantially the same.

In an embodiment, at least two polarities of the first right magnet 427 may be formed on an opposite surface facing the first right coil 441b. For example, an N pole may be formed on a part of the opposing surface and an S pole may be formed on the other part. As such, the first right magnet 427 may include a first right N-pole portion 427a and a first right S-pole portion 427b. The N-pole portion and the S-pole portion may be disposed in a direction substantially parallel to the movement direction of the magnet. In the illustrated embodiment, the first right N-pole portion 427a and the first right S-pole portion 427b may be disposed in the Y-axis direction.

In an embodiment, the first right magnet 427 and the first right coil 441b may electromagnetically interact with each other when a current i is applied to the first right coil 441b. For example, the first right coil 441b may be disposed at a position where it can interact with the magnetic field formed by the first right magnet 427 . For example, the current i applied to the first right coil 441b may be adjusted under the control of a control circuit (eg, the processor 120 of FIG. 1 or the image signal processor 260 of FIG. 2 ).

In one embodiment, the first right magnet 427 and the first right coil 441b shown in FIG. 9 are the optical axes of the image stabilization assembly (eg, the driving unit 420 of FIG. 4 ) in relation to the image stabilization function. Any rotation axis perpendicular to (L) (eg, the first axis of FIG. 5 , and/or the yaw tilt axis) may be moved. Also, in another embodiment, the second magnet 428 and the second coil 442 corresponding thereto rotate the image stabilization assembly (eg, the driving unit 420 of FIG. 4 ) perpendicular to the optical axis L. An axis (eg, the second axis of FIG. 5 , and/or the pitch tilt axis) may be moved around the axis.

Referring to FIG. 9 , the first right coil 441b may be formed by winding a conductive wire. For example, the first right coil 441b may be formed in a form in which a conductive wire is wound a plurality of times. According to an embodiment, the conducting wire of the first right coil 441b may be wound around a predetermined vector extending vertically (eg, substantially in the X-axis direction) from the opposite surface of the first right magnet 427 . . A clockwise or counterclockwise current i may flow through the first right coil 441b substantially in a direction corresponding to the X-axis direction. For example, the direction of the magnetic force applied to the first right coil 441b may be determined according to the direction of the current i flowing through the first right coil 441b.

Referring to FIG. 9 , a first right coil 441b may be disposed in a space in which a magnetic field is formed by the first right magnet 427 . When a current is supplied to the first right coil 441b, a Lorentz force may act on the first right coil 441b in a predetermined direction according to Fleming's left hand rule. Since the first right coil 441b is in a fixed state, a force may act on the first right magnet 427 in a direction opposite to the direction of the Lorentz force (eg, the Y-axis direction). When a current flows in the first right coil 441b in a direction opposite to the current direction of FIG. 9 , a force may act on the first right magnet 427 in the -Y-axis direction.
