[0044] Figure 1 is a schematic cross-sectional view of an exemplary camera module according to one or more embodiments.

[0045] Reference Figure 1 , an exemplary camera module may include: a lens module 100 ; a housing 200 accommodating the lens module 100 ; an image sensor module 300 ; and a first driving unit 400 that moves the image sensor module 300 .

[0046] The lens module 100 may include a lens barrel 110 and a carrier 130 .

[0047] The lens barrel 110 may accommodate at least one lens configured to image a subject. When a plurality of lenses are arranged in the lens barrel 110, the plurality of lenses may be installed in the lens barrel 110 along an optical axis. The lens barrel 110 may be formed in a hollow cylindrical shape.

[0048] The lens barrel 110 may be coupled with the carrier 130. The carrier 130 may be formed in a box shape.

[0049] The lens barrel 110 and the carrier 130 may be accommodated in the housing 200. In an example, the lens module 100 may be fixedly disposed in the housing 200.

[0050] The image sensor module 300 may be disposed under the lens module 100. The image sensor module 300 is a device that converts light incident through the lens module 100 into an electrical signal.

[0051] The image sensor module 300 may include an image sensor 310 and a movable frame 330 on which the image sensor 310 is mounted. A printed circuit board (not shown) may be disposed on the movable frame 330, and the image sensor 310 may be electrically connected to the printed circuit board.

[0052] The image sensor 310 may convert light incident through the lens module 100 into an electrical signal. In a non-limiting example, the image sensor 310 may be a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS).

[0053] The electrical signal converted by the image sensor 310 may be output as an image through a display unit of a portable electronic device on which the camera module is mounted.

[0054] The image sensor module 300 may move in a direction perpendicular to the optical axis (Z axis).

[0055] The camera module according to an example may stabilize an optical image during image capturing by moving the image sensor module 300 in a direction perpendicular to the optical axis (Z axis).

[0056] When the lens module 100 is moved to stabilize an optical image, the camera module may have an increased height by an actuator that moves the lens module 100, etc. However, the camera module according to an example may move the image sensor module 300 instead of the lens module 100 and thus may have a reduced height.

[0057] The first driving unit 400 may generate a driving force to allow the image sensor module 300 to move in a direction perpendicular to the optical axis (Z axis).

[0058] The first driving unit 400 may include a first magnet 410 and a first coil 430. In an example, the first coil 430 may be formed in the shape of a ring having a hollow portion and may be disposed on the lens module 100. The substrate 450 may be disposed on a side surface of the lens module 100, and the first coil 430 may be disposed on the substrate 450.

[0059] The first magnet 410 may be disposed in the hollow portion of the first coil 430. For example, the first magnet 410 may be provided on the image sensor module 300 to be disposed in the hollow portion of the first coil 430.

[0060] The movable frame 330 of the image sensor module 300 may include a main body portion 331 on which the image sensor 310 is disposed and a first extension portion 333 extending from the main body portion 331. An end of the first extension portion 333 may be disposed in a hollow portion of the first coil 430. The first magnet 410 may be disposed at an end of the movable frame 330, for example, at the first extension portion 333 of the movable frame 330.

[0061] The driving force may be generated in a direction perpendicular to the optical axis (Z axis) by the interaction between the first magnet 410 and the first coil 430 .

[0062] The first coil 430 is a fixed member provided on the lens module 100 , and thus the first magnet 410 may be moved in a direction perpendicular to the optical axis (Z axis) by a driving force.

[0063] The first magnet 410 may be disposed on the movable frame 330 , and thus the first magnet 410 and the movable frame 330 may move together in a direction perpendicular to the optical axis (Z axis).

[0064] When the first magnet 410 and the movable frame 330 move in a direction perpendicular to the optical axis (Z axis), a groove portion 131 may be provided in the lens module 100 to prevent the lens module 100 from interfering with the first magnet 410 and the movable frame 330. The lens module 100 may include the groove portion 131 provided on a side surface of the lens module 100 facing the first magnet 410.

[0065] In an example, an elastic member 600 supporting movement of the movable frame 330 may be provided on the movable frame 330. A first end of the elastic member 600 may be coupled to the movable frame 330, and a second end of the elastic member 600 may be connected to the housing 200.

[0066] Figure 2 shows the arrangement of the first magnet and the first coil of the first drive unit; and Figure 3is a schematic plan view of a first driving unit of a camera module according to one or more embodiments.

[0067] Reference Figure 2 In an example, the first coil 430 may have a ring shape with a hollow portion, and the first magnet 410 may be disposed in the hollow portion of the first coil 430 .

[0068] In an example, the first magnet 410 may include two magnets 411 and 413 disposed to be spaced apart from each other in the optical axis (Z-axis) direction.

[0069] The two magnets 411 and 413 may each be fixed to the movable frame 330. For example, one of the two magnets 411 and 413, such as magnet 411, may be fixed to the upper surface of the movable frame 330, and the other of the two magnets, such as magnet 413, may be fixed to the lower surface of the movable frame 330.

[0070] The magnet 411 may have a first polarity 411a and a second polarity 411b in the optical axis (Z axis) direction. The first polarity 411a may be a north (N) pole or a south (S) pole, and the second polarity 411b may be an S pole or a N pole opposite to the first polarity 411a.

[0071] In an example, the magnet 411 may have an N pole upward in the optical axis (Z axis) direction and an S pole downward in the optical axis (Z axis) direction. However, the magnet 411 is not limited to this polarity arrangement, and its polarity arrangement may be opposite.

[0072] The magnet 413 may have a first polarity 413a and a second polarity 413b in the optical axis (Z axis) direction. The first polarity 413a may be a polarity of an N pole or an S pole, and the second polarity 413b may be a polarity of an S pole or an N pole opposite to the first polarity 413a.

[0073] In an example, the magnet 413 may have an S pole upward in the optical axis (Z axis) direction and an N pole downward in the optical axis (Z axis) direction. However, the magnet 413 is not limited to this polarity arrangement, and its polarity arrangement may be opposite.

[0074] The N pole may be each surface of the two magnets 411 and 413 directly facing the inner surface of the first coil 430, and the S pole may be each surface opposite thereto. However, each of the two magnets 411 and 413 is not limited to this polarity arrangement, and this polarity arrangement may be opposite.

[0075] The two magnets 411 and 413 may be arranged to allow their magnetic poles having the same polarity to be opposed to each other in the optical axis (Z-axis) direction.

[0076] For example, the S pole of the magnet 411 and the S pole of the magnet 413 may be opposite to each other in the Z-axis direction. Alternatively, the N pole of the magnet 411 and the N pole of the magnet 413 may be disposed opposite to each other in the Z-axis direction.

[0077] Reference Figure 2 , a driving force may be generated in a direction perpendicular to the optical axis (Z axis), for example, in the direction of the first axis (X axis), through interaction between the two magnets 411 and 413 and the first coil 430 .

[0078] Therefore, the image sensor module 300 on which the first magnet 410 is mounted may move in a direction perpendicular to the optical axis (Z axis).

[0079] According to one or more embodiments, the camera module may have the first magnet 410 disposed in the hollow portion of the first coil 430 , thereby reducing the size of the first magnet 410 , and thus may have a reduced overall height.

[0080] Reference Figure 3 According to one or more embodiments, the camera module may include a plurality of first drive units 400. In an example, the camera module may have four first drive units 400. Two of the first drive units 400 may be arranged to be spaced apart from each other in a first axis (X axis) direction perpendicular to the optical axis (Z axis), and the other two of the first drive units 400 may be arranged to be spaced apart from each other in a second axis (Y axis) direction perpendicular to both the optical axis (Z axis) and the first axis (X axis). However, the first drive unit 400 is not limited to this arrangement, and one first drive unit 400 may be provided for each axis.

[0081] Therefore, the first driving units 400 may each generate a driving force Fx in the first axis (X axis) direction, and a driving force Fy in the second axis (Y axis) direction.

[0082] Figure 4 yes Figure 3 A modified example of the first drive unit is shown.

[0083] Reference Figure 4 According to one or more embodiments, the camera module may include three first driving units 400. The three first driving units 400 may be arranged to be spaced apart from each other at intervals of 120°.

[0084] In addition, in an example, the magnitude of the driving force generated from each first driving unit 400 may be adjusted to generate a driving force Fx in the first axis (X axis) direction and a driving force Fy in the second axis (Y axis) direction.

[0085] Figure 5is a schematic cross-sectional view of an exemplary camera module according to one or more embodiments.

[0086] Reference Figure 5 According to one or more embodiments, the camera module may include a lens module 100, a housing 200 accommodating the lens module 100, an image sensor module 300', and a second driving unit 500 that moves the image sensor module 300'.

[0087] The image sensor module 300 ′ may move in the optical axis (Z-axis) direction.

[0088] According to one or more embodiments, the camera module may adjust the focus by moving the image sensor module 300 ′ in the Z-axis direction.

[0089] When the lens module 100 is moved to adjust the focus, the camera module may have an increased height by moving an actuator of the lens module 100, etc. However, according to one or more embodiments, the camera module may move the image sensor module 300' instead of the lens module 100 and thus may have a reduced height.

[0090] The second driving unit 500 may generate a driving force to allow the image sensor module 300 ′ to move in the optical axis (Z-axis) direction.

[0091] The second driving unit 500 may include a second magnet 510 and a second coil 530. The second coil 530 may be formed in the shape of a ring having a hollow portion and may be disposed in the housing 200. The second coil 530 may be disposed to surround the image sensor module 300'. That is, the image sensor module 300' may be disposed in the hollow portion of the second coil 530.

[0092] The second magnet 510 may be disposed in the hollow portion of the second coil 530. For example, the second magnet 510 may be disposed on the image sensor module 300' to be positioned in the hollow portion of the second coil 530.

[0093] The movable frame 330' of the image sensor module 300' may include a main body portion 331 on which the image sensor 310 is disposed and a second extension portion 335 extending from the main body portion 331. A first end of the second extension portion 335 may be disposed in a hollow portion of the second coil 530. The second magnet 510 may be disposed at a first end of the movable frame 330', for example, at the second extension portion 335 of the movable frame 330'.

[0094] The driving force may be generated in the Z-axis direction through the interaction between the second magnet 510 and the second coil 530 .

[0095] The second coil 530 is a fixed member provided in the housing 200 , and thus the second magnet 510 may be moved in the Z-axis direction by a driving force.

[0096] The second magnet 510 may be disposed on the movable frame 330 ′, and thus the second magnet 510 and the movable frame 330 ′ may move together in the Z-axis direction.

[0097] Figure 6 The arrangement of the second magnet and the second coil of the second drive unit is shown.

[0098] Reference Figure 6 , the second coil 530 may have a ring shape with a hollow portion, and the second magnet 510 may be disposed in the hollow portion of the second coil 530 .

[0099] The second magnet 510 may include a plurality of magnets spaced apart from each other in a direction perpendicular to the optical axis (Z axis). For example, the second magnet 510 may include two magnets spaced apart from each other in a first axis (X axis) direction and another two magnets spaced apart from each other in a second axis (Y axis) direction.

[0100] The second magnet 510 may have a first polarity 511a and a second polarity 511b in a direction perpendicular to the optical axis (Z axis). The first polarity 511a may be a north (N) pole or a south (S) pole, and the second polarity 511b may be an S pole or a N pole opposite to the first polarity 511a.

[0101] For example, a first surface of the second magnet 510 directly facing the inner surface of the second coil 530 may have an N pole, and an opposing second surface may have an S pole. However, the second magnet 510 is not limited to this polarity arrangement, and its polarity arrangement may be opposite.

[0102] Reference Figure 6 , the driving force Fz can be generated in the Z-axis direction through the interaction between the second magnet 510 and the second coil 530.

[0103] Therefore, the image sensor module 300 ′ on which the second magnet 510 is mounted may move in the optical axis (Z-axis) direction.

[0104] According to one or more embodiments, the camera module may have the second magnet 510 disposed in the hollow portion of the second coil 530 , thereby reducing the size of the second magnet 510 , and thus may have a reduced overall height.

[0105] Figure 7 and Figure 8 They are shown respectively Figure 5 and Figure 6A modified example of the second drive unit is shown.

[0106] Reference Figure 7 , the second driving unit 500 ′ may include a plurality of second magnets 510 ′ and a plurality of second coils 530 ′.

[0107] The plurality of second coils 530 ′ may each be formed in a ring shape having a hollow portion, and the plurality of second magnets 510 ′ may each be disposed in each hollow portion of the plurality of second coils 530 ′.

[0108] Each of the plurality of second magnets 510 ′ may include two magnets 511 and 513 disposed to be spaced apart from each other in a direction perpendicular to the optical axis (Z axis).

[0109] The two magnets 511 and 513 may each be fixed to the movable frame 330 ′.

[0110] The movable frame 330' of the image sensor module 300' may include a main body portion 331 on which the image sensor 310 is disposed and a second extension portion 335' extending from the main body portion 331. An end of the second extension portion 335' may be disposed in a hollow portion of the second coil 530'. A plurality of second magnets 510' may be disposed at an end of the movable frame 330', for example, at the second extension portion 335' of the movable frame 330'.

[0111] The two magnets 511 and 513 may each have a first polarity 511a' and a second polarity 511b' in a direction perpendicular to the optical axis (Z axis). The first polarity 511a' may be a polarity of a north (N) pole or a south (S) pole, and the second polarity 511b' may be a polarity of an S pole or a N pole opposite to the first polarity 511a'.

[0112] In an example, the N pole may be each surface of the two magnets 511 and 513 directly facing the inner surface of the second coil 530', and the S pole may be each surface opposite thereto. However, each of the two magnets 511 and 513 is not limited to this polarity arrangement, and this polarity arrangement may be opposite.

[0113] The two magnets 511 and 513 may be disposed to allow their magnetic poles having the same polarity to face each other in a direction perpendicular to the optical axis (Z axis).

[0114] For example, the S pole of magnet 511 and the S pole of magnet 513 may be opposite to each other in a direction perpendicular to the optical axis (Z axis).
