[0043] Figure 2 This is a block diagram illustrating a camera module according to an embodiment of the present disclosure.

[0044] Refer to the block diagram 200 shown. Figure 2 The camera module 180 may include a lens assembly 210, a flash 220, an image sensor 230, an image stabilizer 240, a memory 250 (e.g., a buffer memory) or an image signal processor 260.

[0045] In embodiments, at least one of the components included in the camera module 180 (e.g., lens assembly 210, flash 220, image sensor 230, image stabilizer 240, and memory 250) may be in an electronic device (e.g., Figure 1 The control circuit of the electronic device 101 (e.g., Figure 1 It operates under the control of the processor 120. For example, the control circuit (e.g., Figure 1 The processor 120 in the middle may include a main processor (e.g., Figure 1 The main processor 121) and / or auxiliary processor (e.g. Figure 1 (Auxiliary processor 123) or image signal processor 260).

[0046] Lens assembly 210 can capture light emitted or reflected from an object whose image is to be captured. Lens assembly 210 may include one or more lenses. According to an embodiment, camera module 180 may include multiple lens assemblies 210. In this case, camera module 180 may form, for example, a dual-camera, a 360-degree camera, or a spherical camera. Some of the multiple lens assemblies 210 may have the same lens properties (e.g., angle of view, focal length, autofocus, f-number, or optical zoom), or at least one lens assembly may have one or more lens properties that are different from the lens properties of the other lens assemblies. Lens assembly 210 may include, for example, a wide-angle lens or a telephoto lens.

[0047] The flash 220 is capable of emitting light, wherein the emitted light is used to enhance light reflected from an object. According to an embodiment, the flash 220 may include one or more light-emitting diodes (LEDs) (e.g., red-green-blue (RGB) LEDs, white LEDs, infrared (IR) LEDs, or ultraviolet (UV) LEDs) or xenon lamps. The image sensor 230 acquires an image corresponding to the object by converting light emitted or reflected from the object and transmitted through the lens assembly 210 into an electrical signal.

[0048] According to an embodiment, image sensor 230 may include one image sensor selected from a plurality of image sensors with different properties (e.g., an RGB sensor, a black-and-white (BW) sensor, an IR sensor, or a UV sensor), a plurality of image sensors having the same properties, or a plurality of image sensors with different properties. Each image sensor included in image sensor 230 may be implemented using, for example, a charge-coupled device (CCD) sensor or a complementary metal-oxide-semiconductor (CMOS) sensor.

[0049] Image stabilizer 240 can move image sensor 230 or at least one lens included in lens assembly 210 in a specific direction, or control the operable properties of image sensor 230 (e.g., adjust readout timing) in response to movement of camera module 180 or electronics 101 including camera module 180. This allows compensation for at least a portion of the negative effects (e.g., image blur) caused by movement of the image being captured. According to embodiments, image stabilizer 240 can use a gyroscope sensor (not shown) or an accelerometer sensor (not shown) disposed within or outside camera module 180 to sense such movement of camera module 180 or electronics 101. According to embodiments, image stabilizer 240 can be implemented as, for example, an optical image stabilizer.

[0050] Memory 250 may at least temporarily store at least a portion of the images acquired via image sensor 230 for subsequent image processing tasks. For example, if multiple images are captured rapidly or image capture is delayed due to shutter lag, the acquired raw images (e.g., Bayer pattern images, high-resolution images) may be stored in memory 250, and their corresponding copy images (e.g., low-resolution images) may be previewed via display module 160. Then, if specified conditions are met (e.g., by user input or system command), at least a portion of the raw images stored in memory 250 may be acquired and processed by, for example, image signal processor 260. According to embodiments, memory 250 may be configured as at least a portion of memory 130, or memory 250 may be configured as a separate memory operating independently of memory 130.

[0051] Image signal processor 260 can perform one or more image processing operations on images acquired via image sensor 230 or stored in memory 250. The one or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature point extraction, image compositing, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Alternatively or additionally, image signal processor 260 can perform control (e.g., exposure time control or readout timing control) on at least one component included in camera module 180 (e.g., image sensor 230). Images processed by image signal processor 260 can be stored back in memory 250 for further processing, or the image can be provided to external components outside camera module 180 (e.g., memory 130, display device 160, electronic device 102, electronic device 104, or server 108).

[0052] According to embodiments, the image signal processor 260 can be configured as at least a part of the processor 120, or the image signal processor 260 can be configured as a separate processor that operates independently of the processor 120. If the image signal processor 260 is configured as a separate processor from the processor 120, the processor 120 can display at least one image processed by the image signal processor 260 as is via the display module 160, or the at least one image can be displayed after further processing.

[0053] According to an embodiment, the electronic device 101 may include a plurality of camera modules 180 with different attributes or functions. In this case, at least one of the plurality of camera modules 180 may form, for example, a wide-angle camera, and at least another of the plurality of camera modules 180 may form a telephoto camera. Similarly, at least one of the plurality of camera modules 180 may form, for example, a front-facing camera, and at least another of the plurality of camera modules 180 may form a rear-facing camera.

[0054] The plurality of camera modules 180 may include at least one of a wide-angle camera, a telephoto camera, and an IR (infrared) camera (e.g., a time-of-flight (TOF) camera, a structured light camera). According to an embodiment, the IR camera may serve as a sensor module (e.g., Figure 1 The sensor module 176) operates as at least a part of the sensor module. For example, a TOF camera can be used as a sensor module (e.g., Figure 1 At least a portion of the operation of the sensor module 176 is used to detect the distance to an object.

[0117] In one embodiment, circuit board 464 may be disposed on the lower surface of camera assembly 460 such that image sensor 463 is aligned with the optical axis L of lens 461. For example, when moving component 402 moves (e.g., when camera module 400 performs image stabilization), circuit board 464 may move together with lens 461, thus maintaining the distance between circuit board 464 and lens 461.

[0118] In an embodiment, the retainer 470 may include a first magnet 471 facing the first coil 431, a second magnet 472 facing the second coil 432, and a third magnet 473 facing the third coil 433. In another embodiment, the retainer 470 may further include a magnetic yoke (not shown) disposed between the magnets 471, 472, and 473 and the lens 461. For example, the magnetic yoke may shield the magnetic fields of the magnets 471, 472, and 473 so that the magnetic fields do not affect electrical components (e.g., circuit boards and image sensors) disposed within the camera assembly 460.

[0119] In the illustrated embodiment, the first magnet 471 can be arranged along the -X-axis direction, the second magnet 472 can be arranged along the -Y-axis direction, and the third magnet 473 can be arranged along the X-axis direction.

The moving part 402 can be moved within the camera housing 410 by electromagnetic forces. For example, when current flows through the first coil 431, electromagnetic forces can be applied to the first magnet 471 facing the first coil 431. For example, when current flows through the second coil 432, electromagnetic forces can be applied to the second magnet 472 facing the second coil 432. For example, when current flows through the third coil 433, electromagnetic forces can be applied to the third magnet 473 facing the third coil 433.

[0123] Reference Figure 6 The movable component 402 can move within the camera housing 410 of the fixed component 401. For example, the movable component 402 can move such that the optical axis L of the lens 461 forms a predetermined angle θ with the Z-axis. For example, the movable component 402 can rotate about a rotation axis that is parallel or perpendicular to the optical axis L of the lens 461.

[0124] According to embodiments, rotational motion (e.g., 3-axis rotational motion) associated with the movement of the moving component 402 may include rolling motion, pitching motion, or yawing motion. For example, rotational motion perpendicular to the optical axis L (e.g., substantially parallel to) Figure 9The movement associated with the axis of the first diagonal C1 can be defined as rolling motion, and is related to any other axis of rotation perpendicular to the optical axis L (e.g., substantially parallel to the optical axis). Figure 9 The movement associated with the axis of the second diagonal C2 can be defined as pitch motion. Alternatively, for example, the movement associated with a rotation axis substantially parallel to (matching) the optical axis L can be defined as yaw motion. According to various embodiments, the rotation axis parallel to the optical axis L can be an axis orthogonal to the orthogonal planes of the roll and pitch motions.

[0125] In various embodiments, the moving member 402 can be configured to rotate about the optical axis L and mutually perpendicular rotation axes. The mutually perpendicular rotation axes can include vectors relative to the X and Y axes of the figure or on the xy plane. When the moving member 402 is not rotating, the mutually perpendicular rotation axes can be perpendicular to the optical axis L.

[0126] In an embodiment, the movable component 402 may be configured such that at least a portion of it is surrounded by the sidewall structure 420. For example, the camera assembly 460 and the retainer 470 may be configured such that magnets 471, 472, and 473 disposed on the retainer 470 face coils 431, 432, and 433 disposed on the sidewall structure 420. In an embodiment, a second connecting member 469 extending from the camera assembly 460 may extend through an opening region 4241 in the sidewall structure 420. In an embodiment, the second connecting member 469 may deform or move together with the movable component 402 as the movable component 402 moves.

[0127] In one embodiment, the base 411 of the camera housing 410 may be configured such that its normal vector is substantially parallel to the Z-axis. For example, the moving member 402 may rotate within the camera housing 410 such that the optical axis L of the lens 461 forms a predetermined angle with the normal vector of the base 411.

[0128] In an embodiment, the movable component 402 may include side regions 451, 452, 453, and 454, and a corner region 455 that at least partially faces the sidewall structure 420. The corner region 455 may be formed between adjacent side regions 451, 452, 453, and 454.

[0131] In one embodiment, a first side region 451 may face a first coil 431. A second side region 452 may face a second coil 432. A third side region 453 may face a third coil 433. In another embodiment, side regions 451, 452, 453, and 454 may be spaced apart from a sidewall structure 420 by a predetermined gap, the sidewall structure 420 facing side regions 451, 452, 453, and 454. For example, the first side region 451 may be spaced apart from the first coil 431 by a predetermined gap. The second side region 452 may be spaced apart from the second coil 432 by a predetermined gap. The third side region 453 may be spaced apart from the third coil 433 by a predetermined gap. In another embodiment, the gap may be formed to provide sufficient space for the moving member 402 to move.

[0132] In an embodiment, the corner region 455 may face the support structure 480. For example, the corner region 455 may be adjacent to one or more balls included in the support structure 480 (e.g., Figures 8a to 8c One or more balls 481 may make contact with the corner area 455. In an embodiment, when the moving part 402 moves, the corner area 455 may make substantially point contact with the sidewall structure 420 through one or more balls 481.

[0133] In various embodiments, when the moving part 402 includes the retainer 470, the side regions 451, 452, 453, and 454 and the corner region 455 may include portions of the outer surface of the retainer 470. In various embodiments, when the moving part 402 does not include the retainer 470, the side regions 451, 452, 453, and 454 and the corner region 455 may include portions of the surface of the camera assembly 460.

[0134] In an embodiment, when mechanical noise (e.g., vibration) is applied to the camera module 400 or electronic device (e.g., Figures 3a to 3c When the electronic device 300 is used, the camera module 400 can perform an image stabilization function to reduce noise. For example, the camera module 400 can apply current to coils 431, 432, and 433 to rotate the moving part 402, which includes a lens 461 and an image sensor 463, by a predetermined angle. Therefore, the camera module 400 can obtain a stable image.

[0136] Figure 7b This is a view showing the mounting components of a camera module according to an embodiment of the present disclosure.

[0137] Reference Figure 7a and Figure 7b The fixing component 401 may include a base 411, a sidewall structure 420 formed around a portion of the base 411, a flexible circuit board 430 connected to the sidewall structure 420, and coils 431, 432 and 433 disposed on the flexible circuit board 430.

[0138] In an embodiment, the sidewall structure 420 may include sidewalls 421, 422, 423, and 424, and a support structure 480 disposed between the sidewalls 421, 422, 423, and 424.

[0139] In one embodiment, the first sidewall 421 may have a first opening region 4211 formed therein, in which the first coil 431 is located. The first coil 431 can form the inner surface of the camera housing 410 through the first opening region 4211. In another embodiment, the second sidewall 422 may have a second opening region 4221 formed therein, in which the second coil 432 is located. The second coil 432 can form the inner surface of the camera housing 410 through the second opening region 4221. In another embodiment, the third sidewall 423 may have a third opening region 4231 formed therein, in which the third coil 433 is located. The third coil 433 can form the inner surface of the camera housing 410 through the third opening region 4231. In yet another embodiment, the fourth sidewall 424 may have an opening region 4241 formed therein, in which the second connecting member (e.g., Figure 6 The second connecting member 469 extends through the opening region 4241.

[0140] In an embodiment, the support structure 480 may be disposed between the sidewalls 421, 422, 423 and 424. For example, the support structure 480 may be disposed on a corner sidewall 425 formed between adjacent sidewalls 421, 422, 423 and 424.

[0141] In an embodiment, the flexible circuit board 430 may extend to surround a portion of the first sidewall 421, the second sidewall 422, the third sidewall 423, and the corner sidewall 425. For example, the flexible circuit board 430 may include a first region 430a on which a first coil 431 is disposed, a second region 430b on which a second coil 432 is disposed, and a third region 430c on which a third coil 433 is disposed.

[0142] In one embodiment, a first region 430a of the flexible circuit board 430 can be connected to a first sidewall 421, such that the first coil 431 is located in the first opening region 4211. In another embodiment, a second region 430b of the flexible circuit board 430 can be connected to a second sidewall 422, such that the second coil 432 is located in the second opening region 4221.

[0143] Figures 8a to 8c This is a view showing the support structure of a camera module according to various embodiments of the present disclosure.

[0144] Figure 8a This is a 3D diagram of the support structure for the camera module.

[0145] Figure 8b This is an exploded 3D view of the support structure of the camera module.

[0146] Figure 8c This is an exploded 3D view of the support structure of the camera module.

[0147] Reference Figures 8a to 8c The support structure 480 may be formed on a corner sidewall 425 projecting from the base 411. In an embodiment, the support structure 480 may include one or more balls 481 attached to the corner sidewall 425 for rotatability. For example, the one or more balls 481 may rotate while being received in the corner sidewall 425. For example, the one or more balls 481 may rotate while their position is fixed in the corner sidewall 425. For example, the one or more balls 481 may be configured to roll along the surface of the moving member 402 as the moving member 402 moves.

[0148] In an embodiment, the support structure 480 may further include: a first recess 483 formed on the inner surface 426 of the corner sidewall 425 and therein receiving one or more balls 481; a fixing member 482 at least partially received in the first recess 483 and surrounding at least a portion of the one or more balls 481; a second recess 484 formed on the outer surface 427 of the corner sidewall 425; and a magnetic yoke 485 received in the second recess 484.

[0149] In an embodiment, the fixing member 482 may surround at least a portion of one or more balls 481, such that the one or more balls 481 are rotatable. For example, the fixing member 482 may include one or more openings 4821 in which one or more balls 481 are received. The balls 481 may be located in the openings 4821 respectively. For example, portions of one or more balls 481 may be exposed on the inner surface 426 of the corner sidewall 425 through the openings 4821 of the fixing member 482. In this case, the exposed portions of the balls 481 may interact with a moving component (e.g., Figure 6 The corner area of ​​the moving part 402 (e.g., Figure 6 (455) contact area at the corner.

[0150] In an embodiment, the yoke 485 may be configured to face a fifth magnet included in the moving member 402 (e.g., Figure 9 The fifth magnet 475). The yoke 485 can be connected to the fifth magnet (e.g., Figure 9 The fifth magnet 475 together forms an attractive force. The attractive force can be used to maintain contact between the moving part 402 and one or more balls 481.

[0151] In this embodiment, since the camera module 400 includes one or more balls 481 disposed between the fixed member 401 and the moving member 402 and configured to roll according to the movement of the moving member 402, the camera module 400 can provide rolling friction as the moving member 402 moves. Therefore, when the camera module 400 performs image stabilization, the friction between the moving member 402 and the fixed member 401 can be reduced. Thus, the camera module 400 can smoothly operate the moving member 402 while consuming a relatively small amount of energy.

[0156] Figure 10b It is along Figure 9 The cross-sectional view of the camera module taken by line C1.

[0157] In one embodiment, the fixing component 401 may include a first coil 431, a second coil 432, a third coil 433, and a support structure 480. In another embodiment, the first coil 431 may face the first magnet 471. The second coil 432 may face the second magnet 472. The third coil 433 may face the third magnet 473.

[0158] Reference Figure 9 , Figure 10a and Figure 10b The movable component 402 may include a first corner region 455-1 facing the first corner sidewall 425-1, a second corner region 455-2 facing the second corner sidewall 425-2, a third corner region 455-3 facing the third corner sidewall 425-3, and a fourth corner region 455-4 facing the fourth corner sidewall 425-4.

[0159] In an embodiment, each support structure 480 may include one or more balls 481 and a yoke 485. In an embodiment, the support structure 480 may be formed on a corner sidewall 425. One or more balls 481 included in the support structure 480 may contact the corner region 455 of the moving member 402. For example, one or more balls 481 may make substantially point contact with the corner region 455. For example, the position of one or more balls 481 relative to the corner sidewall 425 may be fixed, but when the moving member 402 moves, one or more balls 481 may roll along the corner region 455 of the moving member 402.

[0160] In one embodiment, the yoke 485 may be positioned facing the fifth magnet 475 disposed on the moving member 402, and the ball 481 may be positioned between the yoke 485 and the fifth magnet 475. For example, the fifth magnet 475 may be disposed on the retainer 470 of the moving member 402. In this case, the yoke 485 and the fifth magnet 475 together can form an attractive force to pull the corner region 455 of the moving member 402 toward the corner sidewall 425 of the fixed member 401.

[0161] In various embodiments, a yoke 485 may be disposed on a corner sidewall 425, and a fifth magnet 475 may be disposed on a corner region 455 of the moving member 402. In various embodiments, two or more magnets (not shown) with different polarities to form an attractive force and facing each other may be disposed on the corner sidewall 425 and the corner region 455.

[0162] In one embodiment, the moving part 402 may include a camera assembly 460 and a retainer 470 surrounding the camera assembly 460. In another embodiment, the moving part 402 may be movably connected to the fixed part 401 via one or more balls 481. For example, movement of the moving part 402 may be supported as one or more balls 481 roll on a surface of the moving part 402 (e.g., a corner region 455).

[0163] Reference Figure 9 , Figure 10a and Figure 10b Camera assembly 460 may include a second camera housing (e.g., Figure 16 The camera assembly 460 includes a second camera housing 460-1 and 460-2, a lens carrier 465, a circuit board 464, a fourth magnet 467, and a fourth coil 468. In one embodiment, one or more balls 466 may be disposed within the camera assembly 460. The balls 466 may be configured to provide rolling friction when the lens carrier 465 moves in the direction of the optical axis L to achieve autofocus.

[0164] In an embodiment, the camera module 400 may include a first connecting member 435 connected to electrical components (e.g., coils 431, 432, and 433) disposed on the fixed member 401, and a second connecting member 469 connected to electrical components (e.g., image sensor 463 and fourth coil 468) disposed on the movable member 402. For example, the second connecting member 469 may be connected to or integrally formed with a circuit board 464.

[0165] In this embodiment, the first connecting member 435 and the second connecting member 469 may extend in different directions. Referring to the figures, the second connecting member 469 may extend through the opening region 4241 of the side wall structure 420 of the camera housing 410 to the outside of the camera housing 410. Referring to the figures, the first connecting member 435 may extend through the region of the side wall structure 420 of the camera housing 410 in which a coil (e.g., a third coil 433) is disposed.

[0166] In one embodiment, one or more balls 481 may be disposed between the corner region 455 of the moving member 402 and the corner sidewall 425 of the fixed member 401. For example, when the moving member 402 rotates, one or more balls 481 may roll along the corner region 455 of the moving member 402. At this time, one or more balls 481 may be attached to the corner sidewall 425 to rotate in place. In some embodiments (e.g., Figure 13 , Figure 14 and Figure 15 In this configuration, one or more balls 481 may be coupled to the movable member 402 for rotatability and may be configured to run along the inner surface of the corner sidewall 425 of the fixed member 401 (e.g., Figures 8a to 8cThe inner surface 426) rolls.

[0167] In this embodiment, when viewed relative to the optical axis L of lens 461, one or more balls 481 may be located at a first distance d1 from the optical axis L of lens 461. When viewed relative to the optical axis L of lens 461, coils (e.g., first coil 431, second coil 432, and third coil 433) may be located at a second distance d2 from the optical axis L of lens 461, where the second distance d2 is less than the first distance d1. When viewed relative to the optical axis L of lens 461, magnets (e.g., first magnet 471, second magnet 472, and third magnet 473) may be located at a third distance d3 from the optical axis L of lens 461, where the third distance d3 is less than the first distance d1. Furthermore, the second distance d2 may be greater than the third distance d3. For example, the first distance d1, the second distance d2, and the third distance d3 may be distances measured from the rotation center C of the optical axis L of lens 461 in a direction perpendicular to the optical axis L of lens 461.

[0168] In the illustrated embodiment, the side surface of the sidewall structure 420 facing the fixed member 401 may be defined on the moving member 402. The side surface may include a side region with a relatively large area (e.g., Figure 6 The camera module 400 according to the embodiment can be configured such that magnets 471, 472, and 473 are arranged on the side regions 451, 452, and 453 having relatively large areas, and one or more balls 481 contact the corner region 455 having relatively small areas. Therefore, magnets 471, 472, and 473, as well as coils 431, 432, and 433, having dimensions sufficient to drive the moving member 402, can be provided in the camera module 400. Although one or more balls 481 are disposed between the corner region 455 having a relatively small area and the corner sidewall 425, the one or more balls 481 can provide rolling friction between the moving member 402 and the stationary member 401.

[0169] Reference Figure 9 , Figure 10a and Figure 10b The support structure 480 can be disposed on the first corner sidewall 425-1, the second corner sidewall 425-2, the third corner sidewall 425-3, and the fourth corner sidewall 425-4. The first corner sidewall 425-1 can face the second corner sidewall 425-2 in the direction of the second diagonal C2. The third corner sidewall 425-3 can face the fourth corner sidewall 425-4 in the direction of the first diagonal C1. In various embodiments, Figure 9 , Figure 10a and Figure 10bThe diagonals C1 and C2 shown may intersect the optical axis L of lens 461 at essentially one point. This point may be referred to as the rotation center C of the moving part 402.

[0170] In various embodiments, reference is made to Figure 9 , Figure 10a and Figure 10b The support structure 480 is shown as being disposed on the corner sidewalls 425 of the fixing member 401. However, it is not necessarily limited to this, the support structure 480 may be disposed on some corner sidewalls 425. For example, one or more balls 481 and their corresponding fifth magnets 475 may not be disposed on some corner sidewalls 425 and their corresponding corner areas 455.

[0171] In various embodiments, the support structure 480 (e.g., Figure 14 and Figure 15 The second support structure 490 can be respectively set on the corner areas 455-1, 455-2, 455-3 and 455-4 of the moving part 402, and the fifth magnet 475 can be respectively set on the corner sidewalls 425-1, 425-2, 425-3 and 425-4 of the fixed part 401.

[0172] In various embodiments, the support structure 480 and the fifth magnet 475 can be symmetrically arranged in the camera module 400. For example, the support structure 480 can be arranged on the first corner sidewall 425-1 and the second corner sidewall 425-2 of the fixed member 401, and the fifth magnet 475 corresponding to the support structure 480 can be arranged on the first corner region 455-1 and the second corner region 455-2 of the moving member 402. Furthermore, the fifth magnet 475 can be arranged on the third corner sidewall 425-3 and the fourth corner sidewall 425-4 of the fixed member 401, and the support structure 480 corresponding to the fifth magnet 475 (e.g., Figure 14 and Figure 15 The second support structure 490 can be disposed on the third corner region 455-3 and the fourth corner region 455-4 of the moving part 402. The positions of the support structure 480 and the fifth magnet 475 are not limited to the embodiment shown, and can be changed according to various embodiments.

[0173] In an embodiment, the moving part 402 may include a first magnet 471, a second magnet 472, a third magnet 473, a fourth magnet 467, and a fifth magnet 475.

[0174] In this embodiment, the first magnet 471, the second magnet 472, and the third magnet 473 may be magnets associated with the image stabilization function of the camera module 400. For example, the first magnet 471, the second magnet 472, and the third magnet 473 may be disposed on the side region of the moving member 402 (e.g., the retainer 470).

[0175] In an embodiment, the fifth magnet 475 may be positioned on the surface of the moving member 402 (e.g., the retainer 470) or may be positioned inside the moving member 402 (e.g., the retainer 470).

[0176] In an embodiment, the fourth magnet 467 may be a magnet associated with the autofocus function of the camera module 400. For example, the fourth magnet 467 may be disposed inside the moving part 402 (e.g., inside the camera assembly 460). For example, the fourth magnet 467 may be disposed closer to the optical axis L of the lens 461 than the first magnet 471, the second magnet 472, and the third magnet 473. Reference will be made below. Figure 16 Describe the autofocus function of camera component 460.

[0177] When viewed relative to the optical axis L of lens 461, the first magnet 471 and the first coil 431 can be arranged along the -X-axis direction. The second magnet 472 and the second coil 432 can be arranged along the -Y-axis direction. The third magnet 473 and the third coil 433 can be arranged along the X-axis direction. The fourth magnet 467 and the fourth coil 468 can be arranged along the Y-axis direction. For example, the fourth magnet 467 can be adjacent to the fourth sidewall of the sidewall structure 420 (e.g., Figure 6 The fourth sidewall 424 is provided. In an embodiment, magnets 471, 472, 473, and 467 may be arranged in different directions so as not to overlap each other. In an embodiment, coils 431, 432, 433, and 468 may be arranged in different directions so as not to overlap each other.

[0178] In an embodiment, when viewed relative to the optical axis L of lens 461, ball 481 can be arranged in a direction that does not overlap with the arrangement directions of magnets 471, 472, 473 and 467 and coils 431, 432, 433 and 468.

[0180] Figure 11a This illustrates the second diagonal C2 surrounding the camera module according to an embodiment (e.g., Figure 9 C2) View of the rotating moving part.

[0181] Figure 11b This illustrates the first diagonal C1 surrounding the camera module according to an embodiment (e.g., Figure 9 C1) View of the rotating moving part.

[0182] Reference Figure 11a and Figure 11b The moving part 402 can be configured to move within the camera housing 410. For example, the moving part 402 can be configured to rotate about a rotation center C. For example, the moving part 402 can rotate about a second diagonal C2, such that the optical axis L of the lens 461 forms a predetermined first angle θ1 with the Z-axis. For example, the moving part 402 can rotate about a first diagonal C1, such that the optical axis L of the lens 461 forms a predetermined second angle θ2 with the Z-axis.

[0183] In one embodiment, the rotation center C of the moving part 402 may be a virtual point through which the optical axis L of the lens 461 passes, and may be defined as a virtual point where the first diagonal C1 and the second diagonal C2 intersect each other. In various embodiments, the rotation center C may be the center point of the image sensor 463.

[0184] In the illustrated embodiment, as the moving component 402 rotates, the ball 481 can roll and simultaneously contact a portion of the corner region 455 of the moving component 402. The area of ​​the corner region 455 that contacts the ball 481 can be defined as the contact region 456. In this embodiment, the contact region 456 can be formed by a spherical surface. In this case, the center of the spherical surface can substantially coincide with the rotation center C of the moving component 402.

[0185] Figure 11a The first corner region 455-1 and the second corner region 455-2 shown can face each other in the direction of the first diagonal C1 in the moving part 402.

[0186] Reference Figure 11a The first contact area 456-1, included in the first corner region 455-1 of the moving member 402, can be formed by a spherical surface centered on the rotation center C. The second contact area 456-2, included in the second corner region 455-2 of the moving member 402, can also be formed by a spherical surface centered on the rotation center C. For example, the first contact area 456-1 and the second contact area 456-2 can be formed by a spherical surface forming substantially the same virtual sphere. Therefore, the moving member 402 can rotate about the rotation center C while maintaining point contact with the sphere 481. In an embodiment, the first contact area 456-1 and the second contact area 456-2 can have regions corresponding to the angle at which the moving member 402 can rotate.

[0187] Figure 11bThe third corner region 455-3 and the fourth corner region 455-4 shown can face each other in the direction of the second diagonal C2 in the moving part 402.

[0188] Reference Figure 11b The third contact area 456-3, included in the third corner region 455-3 of the moving member 402, can be formed by a spherical surface centered on the rotation center C. The fourth contact area 456-4, included in the fourth corner region 455-4 of the moving member 402, can also be formed by a spherical surface centered on the rotation center C. For example, the third contact area 456-3 and the fourth contact area 456-4 can be formed by spherical surfaces forming substantially the same virtual sphere. Therefore, the moving member 402 can rotate about the rotation center C while maintaining point contact with the sphere 481. In an embodiment, the third contact area 456-3 and the fourth contact area 456-4 can have regions corresponding to the angle at which the moving member 402 can rotate.

[0189] In an embodiment, a plurality of balls 481 may be formed. For example, the plurality of balls 481 may be configured such that at least one of them contacts each corner region 455. In an embodiment, the balls 481 may be attached to the inner surface of the corner sidewall 425 for rotatability. The balls 481 may be attached to the inner surface of the corner sidewall 425 for rotation in place. For example, a fixed member (e.g.,) may accommodate the balls 481 for rotatability. Figures 8a to 8c The fixing member 482 may be provided on the inner surface of the corner sidewall 425. In some embodiments (not shown), a recess may be formed on the inner surface of the corner sidewall 425, in which the ball 481 is received so that it can be rotated.

[0190] Figure 11a The first corner sidewall 425-1 and the second corner sidewall 425-2 shown can face each other in the direction of the first diagonal C1 in the fixing member 401.

[0191] Reference Figure 11a A portion of the inner surface of the first corner sidewall 425-1 may be formed by a spherical surface centered on the rotation center C of the moving member 402. For example, the spherical surface may correspond to the spherical surface of the first contact area 456-1. In various embodiments, a portion of the inner surface of the second corner sidewall 425-2 may be formed by a spherical surface centered on the rotation center C of the moving member 402. For example, the spherical surface may correspond to the spherical surface of the second contact area 456-2.

[0192] Figure 11b The third corner sidewall 425-3 and the fourth corner sidewall 425-4 shown can face each other in the direction of the first diagonal C2 in the fixing member 401.

[0193] Reference Figure 11b A portion of the inner surface of the third corner sidewall 425-3 may be formed by a spherical surface centered on the rotation center C of the moving member 402. For example, the spherical surface may correspond to the spherical surface of the third contact area 456-3. In various embodiments, a portion of the inner surface of the fourth corner sidewall 425-4 may be formed by a spherical surface centered on the rotation center C of the moving member 402. For example, the spherical surface may correspond to the spherical surface of the fourth contact area 456-4.

[0194] In this embodiment, the base 411 of the camera housing 410 and the lower surface 457 of the moving member 402 can be separated from each other by a predetermined gap G. In this case, the predetermined gap G can vary according to the rotation of the moving member 402. The predetermined gap G can form a space in which the moving member 402 can rotate.

[0195] In one embodiment, the corner region 455 of the moving member 402 may be formed by a raised spherical surface, such that the lower surface 457 of the moving member 402 is spaced apart from the base 411 of the camera housing 410 by a predetermined gap G. For example, the raised spherical surface of the corner region 455 may be supported by the inner surface of the corner sidewall 425, which is formed to be relatively concave and can maintain at least a predetermined gap with the base 411.

[0196] In an embodiment (not shown), the lower surface 457 of the moving member 402 may be formed with a different thickness. For example, the lower surface 457 may include a central region and a stepped region, with at least a portion of the image sensor 463 disposed on the central region, and the stepped region surrounding the central region and formed in a stepped manner compared to the central region. For example, the stepped region may be formed such that when the moving member 402 is in a default state, the vertical distance (e.g., gap) in the Z-axis direction from the base 411 to the lower surface 457 (e.g., the peripheral region of the lower surface 457) is greater than the vertical distance (e.g., gap) of the central region. For example, the lower surface 457 may be formed in a stepped shape. The default state may refer, for example, a state in which the moving member 402 does not perform rotational movement and the Z-axis and the optical axis L are substantially parallel to each other.

[0197] In one embodiment, the lower surface 457 may include a central region and a sloped region, with at least a portion of the image sensor 463 disposed on the central region, and the sloped region surrounding the central region and formed in a stepped manner compared to the central region. The sloped region may be a region that extends obliquely from the central region when viewed in cross-section. The sloped region may be formed such that the lower surface of the circuit board 464 (e.g., the surface facing the -Z-axis direction) slopes upward in the positive direction +L of the optical axis L. In various embodiments, the sloped region may have a smaller thickness than the central region. The sloped region may have a thickness that gradually decreases from the central region toward the periphery of the circuit board 464.

[0198] In an embodiment, when the moving member 402 moves (e.g., rotates), the vertical distance between the lower surface 457 and the base 411 can be related to the distance measured from the optical axis L of the lens 461 to the stepped region of the lower surface 457 in a direction perpendicular to the optical axis L. For example, as the distance from the optical axis increases, the starting point of the stepped region of the lower surface 457 can move further in the direction toward the base 411. Therefore, the stepped region can be formed in a region relatively far from the optical axis L to keep the gap from the base 411 as small as possible.

[0199] In an embodiment (not shown), the circuit board 464 may have a recess or opening in its upper surface (e.g., the surface facing the Z-axis), in which the image sensor 463 is housed. For example, the camera module 400 can be made compact by positioning the circuit board 464 closer to the base 411. In an embodiment, the image sensor 463 may be provided as a chip-on-film (COF), or at least a portion of the image sensor 463 may be formed as a curved surface. For example, the surface may be formed such that, when viewed relative to the image sensor 463, the center of curvature is located in the direction where the lens 461 is located (e.g., the upward direction relative to the image). For example, the image sensor 463 may be formed to protrude in the downward direction relative to the image (e.g., in the direction toward the base 411). In various embodiments, the center of curvature of the surface may match the center of rotation C.

[0200] Figure 12 This is a view illustrating the operation of a moving component of a camera module according to an embodiment of the present disclosure.

[0201] Reference Figure 12 The movable component 402 can be configured to move within the camera housing 410. For example, the movable component 402 can be configured to rotate about the optical axis L of the lens 461.

[0202] In the illustrated embodiment, as the moving member 402 rotates, the ball 481 can roll and simultaneously contact the contact area 456 of the corner region 455 of the moving member 402. In this embodiment, the contact area 456 can be formed by a spherical surface. In this case, the center of the spherical surface can substantially match the rotation center C through which the optical axis L of the lens 461 passes.

[0203] In one embodiment, ball 481 may be attached to the corner sidewall 425 of fixed member 401 so as to be rotatable, and when moving member 402 rotates, ball 481 may roll along the contact area 456 of corner area 455 of moving member 402.

[0204] In an embodiment, the contact area 456 of the corner region 455 may be formed by a spherical surface. For example, the spherical surface may be part of a virtual sphere centered on the rotation center C. In the illustrated embodiment, the contact area 456 included in the respective corner region 455 may form a virtual sphere having substantially the same center. Therefore, the moving member 402 may rotate about the rotation center C while maintaining point contact with the sphere 481.

[0205] In various embodiments, the corner sidewall 425 may be formed from a spherical surface corresponding to the contact area 456 of the corner region 455. For example, at least a portion of the corner sidewall 425 may have a smaller curvature (e.g., a larger radius of curvature) than the contact area 456.

[0206] In this embodiment, the side surface of the movable member 402 may be separated from the side wall of the fixed member 401 by a predetermined gap G. In this case, the predetermined gap G can vary according to the rotation of the movable member 402. The predetermined gap G can form a space in which the movable member 402 can rotate.

[0207] In this embodiment, the moving member 402 can rotate about the optical axis L of the lens 461 through the interaction between the third coil 433 and the third magnet 473 facing the third coil 433. For example, when the third coil 433 is located in the magnetic field formed by the third magnet 473 and a current is applied to the third coil 433, an electromagnetic force (e.g., Lorentz force) can act on the third coil 433. At this time, the moving member 402, including the third magnet 473, can move because the third coil 433 is located on the fixed member 401, whose position is fixed.

[0208] In one embodiment, when current flows through the third coil 433 in the opposite direction, the moving member 402 can rotate in the opposite direction. In another embodiment, the intensity of the current flowing through the third coil 433 can be related to the rotation angle θ of the moving member 402.

[0209] In an embodiment, the processor (e.g., Figure 1The processor 120 can rotate the moving part 402 about the optical axis L by controlling the direction and / or intensity of the current flowing through the third coil 433. For example, movement (e.g., rotation) associated with the third coil 433 can be defined as yaw motion. In an embodiment, when the moving part 402 rotates about the optical axis L, the corner regions 455-1, 455-2, 455-3, and 455-4 of the moving part 402 and the diagonal directions facing each other (e.g., the first diagonal C1 and the second diagonal C2) of the corner sidewalls 425-1, 425-2, 425-3, and 425-4 can be moved to different diagonal directions (e.g., the third diagonal C1' and the fourth diagonal C2').

[0210] Figure 13 This is a view showing the moving parts of a camera module according to another embodiment of the present disclosure.

[0211] Figure 14 This is a cross-sectional view showing a camera module according to an embodiment of the present disclosure.

[0212] Figure 15 This is a cross-sectional view showing a camera module according to an embodiment of the present disclosure.

[0213] Reference Figure 13 , Figure 14 and Figure 15 The description of the same components as those described above will be omitted.

[0214] Reference Figure 13 The camera module 400 may include a second support structure 490 formed on a corner region 455 of the movable member 402. In the illustrated embodiment, the second support structure 490 may include a protrusion 492 projecting from the surface of the corner region 455, a recess formed in the protrusion 492, and a ball 491 received in the recess for rotatability. (See also...) Figure 13 The protruding portion 492 can protrude in a direction substantially perpendicular to the optical axis L of the lens 461.

[0215] Reference Figure 14 The ball 491 can be configured such that at least part of it is exposed outside the protrusion 492. At least a portion of the ball 491 can be received in a recess. For example, the ball 491 can be configured such that the volume of the portion received in the recess is greater than the volume of the portion exposed outside the protrusion 492. Therefore, when the moving member 402 moves, the ball 491 can roll along the inner surface of the corner sidewall 425 of the fixed member 401 without separating from the protrusion 492.

[0216] Reference Figure 14 and Figure 15The second support structure 490 may include a fifth magnet 475 disposed on the moving member 402 and a yoke 495 disposed on the corner sidewall 425. A ball 491 may be disposed between the fifth magnet 475 and the yoke 495. An attractive force may act between the fifth magnet 475 and the yoke 495. Therefore, even when the moving member 402 moves, the ball 491 may still contact the inner surface of the corner sidewall 425 of the fixed member 401.

[0217] Reference Figure 14 and Figure 15 A contact area 428 that contacts the ball 491 can be formed on the corner sidewall 425. The contact area 428 can be defined as the area where the ball 491 rolls on the inner surface of the corner sidewall 425 when the moving member 402 moves. The contact area 428 can be formed from a portion of a spherical surface. For example, the spherical surface can have a rotation center C as its center, which is formed inside the moving member 402, and the optical axis L of the lens 461 passes through the rotation center C.

[0218] Reference Figure 14 and Figure 15 A virtual sphere with the same center can be formed by extending the contact area 428 of the corner sidewall 425. The center of the virtual sphere can be the optical axis L of the lens 461 and the virtual diagonal (e.g., Figure 12 The virtual point where the diagonals C1, C2, C1' and C2' intersect, and the virtual diagonals connect to the sphere 491 that faces each other in the diagonal direction and passes through the lens 461. The virtual point can be referred to as the rotation center C of the moving part 402.

[0219] Reference Figure 14 and Figure 15 The corner sidewall 425 may include a protruding wall 494 disposed around the contact area 428. The protruding wall 494 may be formed to surround at least a portion of the contact area 428. For example, the protruding wall 494 may form a space therein accommodating at least a portion of the protrusion 492 of the second support structure 490. For example, the protruding wall 494 may protrude from the corner sidewall 425 toward the moving member 402.

[0220] Reference Figure 14 The protruding wall 494 can be used as a stop to limit the rotation range of the moving part 402. For example, the protruding portion 492 protruding from the corner region 455 of the moving part 402 can be located between the first portion 494-1 and the second portion 494-2 of the protruding wall 494.

[0221] Reference Figure 14When the moving part 402 rotates clockwise, the protrusion 492 shown on the left can contact the first portion 494-1 of the protruding wall 494, while the protrusion 492 shown on the right can contact the second portion 494-2 of the protruding wall 494. (Refer to...) Figure 14 When the moving part 402 rotates counterclockwise, the protrusion 492 shown on the left can contact the second portion 494-2 of the protrusion wall 494, while the protrusion 492 shown on the right can contact the first portion 494-1 of the protrusion wall 494. Therefore, the rotation range of the moving part 402 can be limited.

[0222] Reference Figure 15 The protruding wall 494 can be used as a stop to limit the rotation range of the moving part 402. For example, the protruding portion 492 protruding from the corner region 455 of the moving part 402 can be located between the third portion 494-3 and the fourth portion 494-4 of the protruding wall 494.

[0223] Reference Figure 15 When the moving part 402 rotates clockwise, the protruding part 492 can contact the third part 494-3 of the protruding wall 494. When the moving part 402 rotates counterclockwise, the protruding part 492 can contact the fourth part 494-4 of the protruding wall 494. Therefore, the rotation range of the moving part 402 can be limited.

[0224] In various embodiments, the first portion 494-1, the second portion 494-2, the third portion 494-3, and the fourth portion 494-4 of the protruding wall 494 may be connected together to surround the contact area 428 that contacts the ball 491.

[0225] Reference Figure 15 When viewed relative to the optical axis L of lens 461, ball 491 can be located at a first distance d1 from the optical axis L of lens 461. When viewed relative to the optical axis L of lens 461, coils (e.g., first coil 431, second coil 432, and third coil 433) can be located at a second distance d2 from the optical axis L of lens 461, where the second distance d2 is less than the first distance d1. When viewed relative to the optical axis L of lens 461, magnets (e.g., first magnet 471, second magnet 472, and third magnet 473) can be located at a third distance d3 from the optical axis L of lens 461, where the third distance d3 is less than the first distance d1.

[0226] In the illustrated embodiment, the side surface of the moving member 402 may include a side region with a relatively large area (e.g., Figure 6The camera module 400 according to the illustrated embodiment has side regions 451, 452, 453, and 454 and a corner region 455 formed between the side regions and having a relatively small area. The moving member 402 of the camera module 400 can be configured such that magnets 471, 472, and 473 are arranged on the side regions having a relatively large area, and a ball 491 is rotatably coupled to the corner region 455 having a relatively small area. Therefore, magnets 471, 472, and 473, as well as coils 431, 432, and 433, having dimensions sufficient to drive the moving member 402, can be provided in the camera module 400. Meanwhile, although the ball 491 is disposed between the corner region 455 having a relatively small area and the corner sidewall 425, the ball 491 can provide rolling friction between the moving member 402 and the fixed member 401.

[0227] Figure 16 This is an exploded perspective view of the moving part of a camera module according to an embodiment of the present disclosure.

[0228] Figure 16 The movable component 402 shown may include Figure 6 and Figure 13 The movable part 402 shown.

[0229] Reference Figure 16 The movable component 402 may include a camera assembly 460, second camera housings 460-1 and 460-2, a lens carrier 465, a holder 470, and a circuit board 464. At least one component of the camera assembly 460 according to an embodiment is connected to... Figure 5a and Figure 5b At least one component of the camera module 400 is the same as or similar to that of the camera module 400. Therefore, repeated descriptions will be omitted below.

[0230] In one embodiment, the retainer 470 may be configured to surround the second camera housings 460-1 and 460-2. Magnets 471, 472, and 472 may be disposed on the retainer 470.

[0231] In an embodiment, the second camera housings 460-1 and 460-2 may form an internal space to accommodate the lens carrier 465. For example, the second camera housings 460-1 and 460-2 may include an upper housing 460-1 and a lower housing 460-2. In an embodiment, the upper housing 460-1 may have an opening formed in its upper surface. In an embodiment, the circuit board 464 and the image sensor 463 may be disposed within the lower housing 460-2.

[0232] In this embodiment, the image sensor 463 may be mounted on a circuit board 464, and the circuit board 464 may be fixed to the lower housing 460-2. For example, when the lens carrier 465 moves along the optical axis L, the distance between the image sensor 463 and the lens 461 fixed to the second camera housings 460-1 and 460-2 may change.

[0233] In one embodiment, the lens carrier 465 may include a lens barrel 462. The lens barrel 462 may house at least one lens 461. The lens barrel 462 may be formed to surround the lens 461. In various embodiments, the lens 461 and the lens barrel 462 may be referred to as a lens assembly (e.g., Figure 2 (Lens assembly 210). In an embodiment, the lens carrier 465 is movable (e.g., in the L / -L direction) relative to the optical axis L of the lens 461 in the space between the upper housing 460-1 and the lower housing 460-2. The camera module 400 can perform an autofocus function by moving the lens 461 and the lens carrier 465 in the direction relative to the optical axis L (e.g., in the L / -L direction).

[0234] In an embodiment, camera assembly 460 may include a fourth magnet 467 and a fourth coil 468 for moving lens carrier 465 relative to the optical axis L of lens 461 (e.g., in the L / -L direction). For example, the fourth magnet 467 may be disposed on a side surface of lens carrier 465, and the fourth coil 468 may be disposed on upper housing 460-1 or lower housing 460-2 to substantially face the fourth magnet 467. The fourth magnet 467 and the fourth coil 468 may be in the control circuit (e.g., Figure 1 Processor 120 and / or Figure 2 The image signal processors (260) interact electromagnetically with each other under their control. For example, in the processor (e.g., Figure 1 Processor 120 and / or Figure 2 Under the control of the image signal processor 260, the camera module 400 can control the electromagnetic force by controlling the direction and / or intensity of the current flowing through the fourth coil 468, and can move the lens carrier 465 relative to the optical axis L (e.g., in the L / -L direction) by using the Lorentz force generated by the electromagnetic force.

[0235] In embodiments, camera assembly 460 may further include sensor 4681 configured to sense the position of fourth magnet 467. For example, sensor 4681 may be disposed on upper housing 460-1 or lower housing 460-2. In embodiments, sensor 4681 may detect displacement of lens carrier 465 by measuring the position of fourth magnet 467, which moves with lens carrier 465. For example, sensor 4681 may detect the position of fourth magnet 467 by measuring changes in the magnetic field formed by fourth magnet 467. For example, camera module 400 may measure the position of lens carrier 465 based on the signal detected by sensor 4681. In various embodiments, sensor 4681 may include a Hall sensor.

[0236] In an embodiment, sensor 4681 can detect the displacement of lens carrier 465 and / or fourth magnet 467, and electronic devices (e.g., Figure 1 Electronic device 101 or Figures 3a to 3c The control circuit of the electronic device 300 (e.g., Figure 1 The first processor 120 and / or Figure 2 The image signal processor 260 can provide autofocus using a fourth magnet 467 and a fourth coil 468. For example, the distance between the lens 461 and the image sensor 463 disposed on the second camera housings 460-1 and 460-2 (e.g., the lower housing 460-2) can vary as the lens 461 moves together with the lens mount 465 relative to the optical axis L (e.g., the L / -L direction). As described above, the electronics can adjust the focal length by moving the lens mount 465 according to the distance from the object.

[0237] In an embodiment, camera assembly 460 may include a plurality of balls 466-1 and 466-2 disposed between a side surface of lens carrier 465 and second camera housings 460-1 and 460-2. In an embodiment, when lens carrier 465 moves in the direction of optical axis L, the plurality of balls 466-1 and 466-2 may provide rolling friction between lens carrier 465 and a portion of the second camera housing (e.g., lower housing 460-2). In the illustrated embodiment, the plurality of balls 466-1 and 466-2 may include a first plurality of balls 466-1 disposed on one side of fourth magnet 467. A second plurality of balls 466-2 disposed on the opposite side of fourth magnet 467. For example, the first plurality of balls 466-1 and the second plurality of balls 466-2 may be arranged along the direction of optical axis L of lens 461. In an embodiment, the first plurality of balls 466-1 may be configured to include a smaller number of balls than the second plurality of balls 466-2. For example, due to camera module 400 (e.g., Figure 4The structure of the camera module 400 (e.g., a slanted edge shape or a chamfered region) may include a first plurality of balls 466-1 disposed on one side (e.g., the right side) of the fourth magnet 467, which may include a smaller number of balls than the second plurality of balls 466-2 disposed on the opposite side (e.g., the left side) of the fourth magnet 467.

[0238] In an embodiment, to guide the movement of the lens carrier 465 along the optical axis L, the camera assembly 460 may include a guide member 4651 and a guide rail 4652, wherein the guide member 4651 is accommodated in the guide rail 4652. The guide member 4651 may protrude from a side surface of the lens carrier 465, and the guide rail 4652 may be formed on the upper housing 460-1 or the lower housing 460-2, and may have the guide member 4651 accommodated therein. For example, the guide rail 4652 may be formed on at least a portion of the lower housing 460-2. The guide member 4651 may be accommodated in the guide rail 4652 and may guide the movement of the lens carrier 465 relative to the optical axis L (e.g., in the L / -L direction).

[0239] In one embodiment, the guide rail 4652 may extend from the stepped surface 4653 formed on the lower housing 460-2 and may be open in the upward direction (e.g., the Z-axis direction). When the lens carrier 465 moves in the downward direction (e.g., the -Z-axis direction), the stepped surface 4653 may support the guide member 4651 to limit the range of movement of the lens carrier 465 in the downward direction (e.g., the -L direction).

[0240] Figure 17a and Figure 17b This is a view showing the arrangement of coils and magnets of a camera module according to various embodiments of the present disclosure.

[0241] In this embodiment, the camera module 400 can perform image stabilization and autofocus functions.

[0242] In an embodiment, the camera module 400 may include coils (first coil 431, second coil 432, and third coil 433) and magnets (first magnet 471, second magnet 472, and third magnet 473) associated with image stabilization. The coils 431, 432, and 433, and the magnets 471, 472, and 473, may be configured to electromagnetically interact with each other. The coils 431, 432, and 433, and the magnets 471, 472, and 473, which electromagnetically interact with each other, may be arranged facing each other. For example, the first coil 431 may be configured to interact with the first magnet 471. The first magnet 471 and the first coil 431 may be arranged facing each other.

In another embodiment, the fourth coil 468 may interact with the fourth magnet 467, and the lens carrier 465 may be linearly movable in the direction of the optical axis L of the lens 461.

[0249] Figure 18a and Figure 18b This is a view illustrating the relative motion between the coil and magnet of a camera module according to various embodiments of the present disclosure.

[0250] Figure 18a and Figure 18b The magnets 710 and 730 shown may include Figure 4 , Figure 5a , Figure 5b , Figure 6 , Figure 7a , Figure 7b , Figure 8a , Figure 8b , Figure 8c , Figure 9 , Figure 10a , Figure 10b , Figure 11a , Figure 11b , Figures 12-16 , Figure 17a and Figure 17bThe first magnet 471, the second magnet 472, the third magnet 473, and / or the fourth magnet 467 are shown. Furthermore, Figure 18a and Figure 18b The coils 720 and 740 shown may include Figure 4 , Figure 5a , Figure 5b , Figure 6 , Figure 7a , Figure 7b , Figure 8a , Figure 8b , Figure 8c , Figure 9 , Figure 10a , Figure 10b , Figure 11a , Figure 11b , Figures 12-16 , Figure 17a and Figure 17b The first coil 431, second coil 432, third coil 433, and / or fourth coil 468 are shown. In this embodiment, when a current “i” is applied to the coils 431, 432, 433, and 468, the magnets 471, 472, 473, and 467, as well as the coils 431, 432, 433, and 468, can interact electromagnetically with each other. The coils 431, 432, 433, and 468 can be positioned where they can interact with the magnetic field formed by the magnets 471, 472, 473, and 467.

[0251] In the embodiment, regarding the autofocus function, Figure 18a The magnet 710 and coil 720 shown can be parallel to the optical axis (e.g., Figure 16 The lens is moved in the direction of the optical axis L (e.g., Figure 16 (Lens mount 465). In the embodiment, regarding the image stabilization function, Figure 18a The magnet 710 and coil 720 shown can be positioned relative to a rotation axis perpendicular to the optical axis L (e.g., substantially parallel to). Figure 9 The axis of the first diagonal C1 and / or substantially parallel to Figure 9 The axis of the second diagonal C2) moves the camera assembly (e.g., Figure 6 Moving part 402).

[0252] In the embodiment, regarding the image stabilization function, Figure 18b The magnet 730 and coil 740 shown can rotate about the optical axis L of the lens (e.g., Figure 12 Camera components (e.g., Figure 6 Moving part 402).

[0253] In various embodiments, one of magnets 710 and 730 or coils 720 and 740 may be disposed in a fixed structure (e.g., Figure 5a and Figure 5b Fixing component 401 or Figure 16 The second camera housing 460-1 and 460-2 may be mounted on a movable structure that moves relative to the fixed structure (e.g., Figure 5a and Figure 5b The moving part 402 or Figure 16 On the lens carrier 465.

[0254] For example, in Figure 18a In the illustrated embodiment, when the lens carrier (e.g., Figure 16 When the lens mount 465 moves linearly for autofocus, the coil 720 can be set in the second camera housing (e.g., a fixed structure). Figure 16 The coil 720 is mounted on the second camera housing 460-1 and 460-2, and the magnet 710 can be mounted on the relatively movable lens carrier 465. However, it is not limited to this, and the positions of the coil 720 and the magnet 710 can be changed relative to each other.

[0255] For example, in Figure 18a or Figure 18b In the illustrated embodiment, when the moving part (e.g., Figure 6 When the moving part 402 rotates for image stabilization, coils 720 and 740 can be set in the camera housing (e.g., which is a fixed structure). Figure 6 The magnets 710 and 730 are mounted on the camera housing 410, and the magnets 710 and 730 can be mounted on the movable part 402 that is rotatable relative to the camera housing 410. However, this is not a limitation, and the positions of the coils 720 and 740 and the magnets 710 and 730 can be changed relative to each other.

[0256] In an embodiment, when a current "i" is applied to coils 720 and 740, magnets 710 and 730 and coils 720 and 740 can interact electromagnetically with each other. For example, coils 720 and 740 can be positioned where they can interact with the magnetic field formed by magnets 710 and 730. For example, this can be achieved in a control circuit (e.g., Figure 1 The current “i” applied to coils 720 and 740 is regulated under the control of the processor 120.

[0257] In an embodiment, coils 720 and 740 may be formed as multiple windings of wires 721 and 741. For example, a vector "v" may be defined that extends substantially in the X-axis direction from the opposing surfaces 713 and 733 of magnets 710 and 730 and passes through regions 722 and 742 surrounded by wires 721 and 741. For example, coils 720 and 740 may be formed such that wires 721 and 741 are wound multiple times around vector "v". Current "i" may flow through coils 720 and 740 in a clockwise or counterclockwise direction relative to vector "v".

[0258] Reference Figure 18a The magnet 710 may include a plurality of sub-magnets. For example, the magnet 710 may include two sub-magnets. In an embodiment, the magnet 710 may include a facing surface 713 facing the coil 720. In various embodiments, the magnet 710 may be configured such that the facing surface 713 has at least two polarities. For example, a portion 711 of the facing surface 713 may be formed as an N pole, while another portion 712 of the facing surface 713 may be formed as an S pole. In an embodiment, the N pole and the S pole may be arranged in a direction substantially parallel to the direction in which the N pole and the S pole will move.

[0259] In this embodiment, the current "i" can flow through the coil 720 in either a clockwise or counterclockwise direction. The direction of the magnetic force applied to the coil 720 can be determined based on the direction of the current "i" flowing through the coil 720.

[0260] For example, a current "i" can be applied to coil 720 in a clockwise direction, and a magnetic force (e.g., Lorentz force) in the downward direction (e.g., the -Z-axis direction) can be applied to coil 720. In this case, if coil 720 is arranged on a fixed structure, it is understood that an upward force (e.g., the Z-axis direction) is applied to magnet 710. Furthermore, for example, a current "i" can be applied to coil 720 in a counterclockwise direction, and a magnetic force (e.g., Lorentz force) in the upward direction (e.g., the Z-axis direction) can be applied to coil 720. In this case, if coil 720 is arranged on a fixed structure, it is understood that a downward force (e.g., the -Z-axis direction) is applied to magnet 710. Therefore, magnet 710 can move relative to coil 720 arranged on the fixed structure in an upward or downward direction (e.g., the Z / -Z-axis direction).

[0261] Reference Figure 18bThe magnet 730 may include a plurality of sub-magnets. For example, the magnet 730 may include two sub-magnets. In an embodiment, the magnet 730 may include a facing surface 733 facing the coil 740. In various embodiments, the magnet 730 may be configured such that the facing surface 733 has at least two polarities. For example, a portion 731 of the facing surface 733 may be formed as an N pole, while another portion 732 of the facing surface 733 may be formed as an S pole. In an embodiment, the N pole and the S pole may be arranged in a direction substantially parallel to the direction in which the N pole and the S pole will move.

[0262] In this embodiment, the current "i" can flow through the coil 740 in either a clockwise or counterclockwise direction. The direction of the magnetic force applied to the coil 740 can be determined based on the direction of the current "i" flowing through the coil 740.

[0263] For example, a current "i" can be applied to coil 740 in a clockwise direction, and a magnetic force (e.g., Lorentz force) facing to the left (e.g., -Y-axis direction) relative to the drawing can be applied to coil 740. In this case, if coil 740 is mounted on a fixed structure, it is understood that a force facing to the right (e.g., Y-axis direction) relative to the drawing is applied to magnet 730. Furthermore, for example, a current "i" can be applied to coil 740 in a counterclockwise direction, and a magnetic force (e.g., Lorentz force) facing to the right (e.g., Y-axis direction) relative to the drawing can be applied to coil 740. In this case, if coil 740 is mounted on a fixed structure, it is understood that a force is applied to magnet 730 facing to the left (e.g., -Y-axis direction) relative to the drawing. Therefore, magnet 730 can move relative to coil 740 mounted on the fixed structure in the left-right direction (e.g., Y / -Y-axis direction).

[0264] According to various embodiments (not shown), the magnets and coils disclosed herein are not limited to... Figure 18a and Figure 18b The form shown. For example, the opposing surfaces of a magnet can have a polarity. According to various embodiments, electronic devices (e.g., Figures 3a to 3c The camera module of the electronic device 300 (e.g., Figure 4 The camera module 400 can use a magnet of one polarity and a coil facing the magnet to generate a solenoid force, and can perform rotational motion (e.g., movement) of the camera module 400. For example, the camera module 400 may include a magnetic component (e.g., a solenoid) formed by a wound coil (e.g., a cylindrical coil), and can use the magnetism (N and S poles) formed by allowing current to flow through the coil to move the moving component (e.g., Figure 6 Moving part 402).

[0265] According to various embodiments, attractive or repulsive forces can act between opposing surfaces of a magnet having one polarity and a coil facing the opposing surface. For example, the force can act on the magnet in a direction toward or away from the coil. For example, if the opposing surface of the magnet has a north pole (N pole), an attractive force can be formed between the magnet and the coil when a current is applied to the coil in a clockwise direction. Conversely, if the opposing surface of the magnet has a north pole (N pole), a repulsive force can be formed between the magnet and the coil when a current is applied to the coil in a counterclockwise direction.

[0266] Figure 19a and Figure 19b This is a view showing the coils and magnets of a camera module according to various embodiments of the present disclosure.

[0267] Reference Figure 19a and Figure 19b The moving member 402 can be configured to rotate about a rotation axis parallel to the optical axis L of the lens 461. The moving member 402 may include a magnet 830 and a fixing member (e.g., Figure 17a and Figure 17b The fixing component 401 may include a coil 840 facing the magnet 830.

[0268] The magnet 830 and coil 840 associated with the movement (e.g., yaw motion) of the moving part 402 rotating about a rotation axis parallel to the optical axis L of the lens 461 can be in conjunction with... Figure 18b The magnet 730 and coil 740 shown operate with the same drive scheme.

[0269] In an embodiment, the opposing surface 834 of the magnet 830 facing the coil 840 may have three polarities. For example, the opposing surface 834 may include a first region 831 having a first polarity, a second region 832 having a second polarity, and a third region 833 having a first polarity.

[0270] In one embodiment, coil 840 may include a first coil 841 and a second coil 842. (See reference...) Figure 19b When viewed from the X-axis, a portion of the first coil 841 can overlap with the first region 831, while another portion of the first coil 841 can overlap with the second region 832. When viewed from the X-axis, a portion of the second coil 842 can overlap with the second region 832, while another portion of the second coil 842 can overlap with the third region 833.

[0271] In an embodiment, a portion comprising a conductor extending along the Z-axis may be defined in each of the first coil 841 and the second coil 842. The first coil 841 may include a first portion 841a and a second portion 841b. The second coil 842 may include a third portion 842a and a fourth portion 842b. The first portion 841a, the second portion 841b, the third portion 842a, and the fourth portion 842b may be substantially related to the magnitude of the electromagnetic force between the magnet 830 and the coil 840. For example, the electromagnetic force applied to the magnet 830 may increase as the current flowing through the first portion 841a, the second portion 841b, the third portion 842a, and the fourth portion 842b increases.

[0272] In this embodiment, a first portion 841a of the first coil 841 may overlap with a first region 831 of the magnet 830, and a second portion 841b of the first coil 841 may overlap with a second region 832 of the magnet 830. A third portion 842a of the second coil 842 may overlap with a second region 832 of the magnet 830, and a fourth portion 842b of the second coil 842 may overlap with a third region 833 of the magnet 830.

[0273] In an embodiment, the electromagnetic force formed by the first coil 841 and the magnet 830 and the electromagnetic force formed by the second coil 842 and the magnet 830 can preferably act in the same direction. To achieve this, current can flow in the same direction through the second portion 841b and the third portion 842a that overlap with the second region 832. In an embodiment, the control circuit (e.g., Figure 1 The processor 120 can perform control to cause current to flow through the first coil 841 and the second coil 842 in opposite directions. In this case, an electromagnetic force can be applied to the magnet 830 and the moving part 402 along the Y-axis.

[0274] Included in electronic devices (e.g., Figures 3a to 3c The camera module 400 in the electronic device 300 may have a height limitation in the Z-axis direction to achieve a small thickness of the electronic device 300. For example, as the required performance of the camera module 400 increases, the size of the lens 461 may increase, and the size of the moving part 402 may also increase. To drive the moving part 402 with its increased size, it may be necessary to have coils 840 and magnets 830 with increased sizes. For example, the height limitation in the Z-axis direction may be related to the yaw motion of the moving part 402.

[0275] The rolling and pitching motions of the moving part 402 can be relatively independent of its height in the Z-axis direction. For example, refer to... Figure 18aThe coil 720 and magnet 710 shown can define a Y-axis extension in the coil 720, including a conductor extending along the Y-axis direction. The Y-axis extension can be related to the magnitude of the electromagnetic force. Even if the number of times the conductor of the coil 720 is wound increases to increase the current flowing through the Y-axis extension, the increase in height in the Z-axis direction can be limited.

[0276] Therefore, regarding the yaw motion of the moving part 402, Figure 19a and Figure 19b The camera module 400 shown may include two coils 841 and 842 and a magnet 830 including opposing surfaces 834 with three polarities, thereby increasing the driving force (e.g., electromagnetic force) without increasing the height in the Z-axis direction.
