Abstract
Description
Technical Field
[0001] The various embodiments disclosed herein relate to camera modules and electronic devices including camera modules. Background Technology
[0002] Various electronic devices, such as smartphones, tablet PCs, portable multimedia players (PMPs), personal digital assistants (PDAs), laptop computers (PCs), and wearable devices (such as watches and head-mounted displays (HMDs)), may include cameras and can use cameras to capture images.
[0003] As the number of users taking photos or videos using electronic devices increases, the performance of cameras included in those devices is also improving. For example, when capturing images using a camera included in an electronic device, it may be necessary to correct for camera shake (e.g., hand shakiness) that may occur when adjusting the focus of the subject or taking a picture of the subject in order to obtain a sharp image.
[0004] Camera modules used in electronic devices may include autofocus (AF) functions for automatically adjusting the lens focus on the subject and / or optical image stabilization (OIS) functions for correcting camera shake that occurs within the camera module when shooting the subject. The AF and OIS functions of the camera module may be executed based on the electromagnetic force of magnets and coils.
[0005] The above information is provided as relevant technical information to aid in understanding this disclosure. No determination or assertion is made as to whether any of the above information is applicable as prior art to this disclosure. Summary of the Invention
[0006] Technical issues A camera module can achieve high magnification by using the refraction of light. For example, a camera module may include reflective elements such as prisms or mirrors. Light incident on the reflective element can be reflected or refracted, the light path can be refracted, and thus the light can be transmitted to the image sensor.
[0007] A camera module using a reflective component can be in the form in which a ball guide, an intermediate guide, a reflector actuator, a lens drive, and an image sensor are arranged sequentially inside the camera housing.
[0008] Additionally, the reflector actuator may include a reflective member and a carrier. To correct for image jitter caused by hand tremors on the image sensor, the reflective member may be tilted relative to the image sensor. For example, the carrier on which the reflective member is disposed may be rotated relative to the image sensor about one of a first axis (pitch axis) and a second axis (yaw axis or roll axis) by an actuator (e.g., a coil and a magnet). The intermediate guide portion may be rotated relative to the image sensor about the other of the first and second axes by an actuator. The carrier may rotate together with the intermediate guide portion in the same direction as the rotation of the intermediate guide portion.
[0009] Alternatively, the intermediate guide portion can be a structure used to guide the rotation of the carrier. For example, if the carrier is designed to rotate about a first axis, the intermediate guide portion can guide the rotation of the carrier so that the carrier does not rotate about a second axis.
[0010] Similarly, the ball guide portion can be a configuration for guiding the rotation of the intermediate guide portion. For example, in the case where the carrier is designed to rotate about a second axis different from the carrier's axis of rotation (e.g., the first axis), the intermediate guide portion can guide the rotation of the carrier so that the carrier does not rotate about the first axis.
[0011] The aforementioned camera module structure may include an intermediate guide section for guiding the rotation of the carrier and a ball guide section for guiding the rotation of the intermediate guide section. Even if the arrangement of the carrier, intermediate guide section, and ball guide section is optimized, there may still be limitations on reducing the size of the camera module because one of the components must inevitably be omitted. Furthermore, the more components that make up the camera module, the more complex the assembly process becomes. Therefore, its production cost may increase.
[0012] The technical problems to be solved in this document are not limited to those mentioned above, and other technical problems not mentioned can be clearly understood by those skilled in the art from the following description.
[0013] Solution to the problem A camera module according to various embodiments disclosed herein may include a reflective member. In embodiments, the camera module may include a carrier including a base portion and a guide portion, the reflective member being disposed in the base portion and the guide portion extending from the base portion in a direction opposite to the reflective member. In embodiments, the camera module may include a receiving portion having a guide groove formed thereon to receive at least a portion of the guide portion, and the camera module may include a camera housing in which the carrier is disposed. In embodiments, the camera module may include a guide structure configured to contact at least one of the guide groove and the guide portion at at least three points. In embodiments, the camera module may include a first OIS magnet disposed on a first surface of the carrier. In embodiments, the camera module may include a second OIS magnet disposed on a second surface perpendicular to the first surface of the carrier. In embodiments, the camera module may include a first OIS coil disposed in the camera housing facing the first OIS magnet. In embodiments, the camera module may include a second OIS coil disposed in the camera housing facing a second OIS magnet. In embodiments, the camera module may include a lens drive portion through which light reflected from the reflective member is transmitted. In one embodiment, the camera module may include an image sensor, to which light transmitted from the lens drive portion is incident.
[0014] According to embodiments of this disclosure, an electronic device including a camera module may include a reflective member. Furthermore, the electronic device may include a carrier, the carrier including a base portion in which the reflective member is disposed and a guide portion extending from the base portion in a direction opposite to the reflective member. Additionally, the electronic device may include a receiving portion having a guide groove formed thereon to receive at least a portion of the guide portion, and the electronic device may include a camera housing in which the carrier is disposed. Additionally, the electronic device may include a guide structure configured to contact at least one of the guide groove and the guide portion at at least three points. Furthermore, the electronic device may include a first OIS magnet disposed on a first surface of the carrier. Furthermore, the electronic device may include a second OIS magnet disposed on a second surface perpendicular to the first surface of the carrier. Additionally, the electronic device may include a first OIS coil disposed in the camera housing facing the first OIS magnet. Additionally, the electronic device may include a second OIS coil disposed in the camera housing facing a second OIS magnet. Additionally, the electronic device may include a lens driving portion through which light reflected from the reflective member is transmitted. Additionally, the electronic device may include an image sensor through which light transmitted from the lens driving portion is incident.
[0015] Beneficial effects of the invention According to the embodiments disclosed herein, a structure may include features capable of implementing image stabilization (e.g., optical image stabilization (OIS)). According to the camera module of this disclosure, an intermediate guide portion for guiding the rotation of the carrier and a ball guide portion for guiding the rotation of the intermediate guide portion may be omitted. In embodiments, the carrier may be partially coupled to a receiving portion formed in the camera module, and this may ensure alignment with respect to a first axis (e.g., pitch axis and / or...). Figure 4c The Y-axis), the second axis (e.g., the yaw axis and / or Figure 4c The X-axis and the third axis (e.g., the roll axis and / or Figure 4c The rotational degree of freedom (Z-axis in the equation).
[0016] Furthermore, according to embodiments of this disclosure, the size of the camera module can be reduced by omitting the intermediate guide portion and the ball guide portion. Additionally, production costs can be reduced because the manufacturing process is simplified by reducing the number of components used in the camera module.
[0017] Furthermore, according to embodiments of this disclosure, the center of the reflective surface of the reflective member disposed on the carrier and the rotation center of the reflective member may coincide with each other. In this case, the driving error of the image stabilizer (e.g., optical image stabilizer (OIS)) function used to correct image jitter can be reduced.
[0018] The effects that can be obtained from this disclosure are not limited to those described above, and other effects not mentioned will be clearly understood by those skilled in the art to which this disclosure pertains from the following description. Attached Figure Description

According to embodiments, the auxiliary processor 123 (e.g., a neural processing unit) may include hardware architecture dedicated to artificial intelligence model processing. Artificial intelligence models can be generated through machine learning.

The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. According to an embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0072] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).
[0073] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199.

In another embodiment, external electronic device 104 may include an Internet of Things (IoT) device. Server 108 may be an intelligent server using machine learning and / or neural networks. According to embodiments, external electronic device 104 or server 108 may be included in a second network 199. Electronic device 101 may be applied to intelligent services based on 5G communication technology or IoT-related technologies (e.g., smart homes, smart cities, smart cars, or healthcare).

In this case, the camera module 180 may form, for example, a dual-camera system, 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 differ from the lens properties of the other lens assemblies. The lens assembly 210 may include, for example, a wide-angle lens or a telephoto lens.
[0075] Flash 220 is capable of emitting light, wherein the emitted light is used to enhance light reflected from an object. According to embodiments, 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. Image sensor 230 acquires an image corresponding to an object by converting light emitted or reflected from the object and transmitted through lens assembly 210 into an electrical signal. According to embodiments, 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.
[0076] Image stabilizer 240 may move image sensor 230 or at least one lens included in lens assembly 210 in a specific direction, or control the operability 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 may 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 may be implemented as, for example, an optical image stabilizer. Memory 250 may at least temporarily store at least a portion of the image acquired via image sensor 230 for subsequent image processing tasks. For example, if multiple images are captured rapidly or if image capture is delayed due to shutter lag, the acquired raw images (e.g., Bayer pattern images, high-resolution images) can be stored in memory 250, and their corresponding copy images (e.g., low-resolution images) can 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 can be acquired and processed by, for example, image signal processor 260. According to embodiments, memory 250 can be configured as at least a portion of memory 130, or memory 250 can be configured as a separate memory operating independently of memory 130.
[0077] 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 module 160, electronics 102, electronics 104, or server 108). According to embodiments, image signal processor 260 can be configured as at least a part of processor 120, or image signal processor 260 can be configured as a separate processor operating independently of processor 120. If the image signal processor 260 is configured as a processor separate 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.

In another embodiment, the second AF magnet 451 may face the second AF coil 452 disposed in the third portion 323 of the camera housing 320.
[0088] In an embodiment, the camera module 300 may be configured such that the lens drive portion 310 moves relative to the image sensor 370, thereby being configured to perform an autofocus (AF) function under the control of the processor 120 for automatically adjusting the focus of the lens 3101 on an object outside the electronic device 200.

In an embodiment, the first AF coil 442 and the second AF coil 452 may generate magnetic force when an electric current is applied to the flexible printed circuit board 460.

[0090] According to the embodiments, such as Figure 4a and Figure 4b As shown, the lens drive section 310 can move relative to the camera housing 320 in the X-axis direction by means of AF balls b2, which act as bearing balls. In an embodiment, the AF balls b2 may be arranged in the camera housing 320 in a configuration along the X-axis (e.g., Figure 3b The AF ball b2 can be arranged in the ball guide portion extending in the X-axis direction to guide the movement of the lens drive portion 310 relative to the camera housing 320.
[0091] According to the embodiments, such as Figure 3a , Figure 3b , Figure 4a and Figure 4b As shown, the camera module 300 can achieve high magnification by utilizing the refraction of light. In an embodiment, light incident on the camera module 300 can be reflected or refracted by a reflector actuator. Therefore, the light path can be altered, and thus the light can be introduced into the image sensor 370 after passing through the lens drive section 310.
[0092] According to the embodiments, such as Figure 3b , Figure 4a and Figure 4bAs shown, the reflector actuator may include a reflective member R and a carrier 340 on which the reflective member R is disposed.

[0093] In the embodiments, refer to the following description Figure 5b , Figure 9 and Figure 12a The reflecting member R may include an incident surface S1 on which light is incident and a reflecting surface S3 from which light is reflected or refracted (e.g., Figure 12a The incident surface S1 and the exit surface S2 from which incident light is emitted are both reflected (S1 and S2). In an embodiment, the incident surface S1 and the exit surface S2 may be substantially perpendicular. In an embodiment, the reflective surface S3 may be the surface connecting the incident surface S1 and the exit surface S2, and at least a portion of it faces the base portion of the carrier 340 (e.g., ...). Figure 9 The first inclined surface 3411 of the base portion 341). In an embodiment, light incident on the incident surface S1 of the reflecting member R can be reflected from the reflecting surface S3, pass through the exit surface S2, and be introduced into the image sensor 370 through the lens 3101 of the lens drive portion 310.
[0094] In the embodiments, refer to the following description Figure 5b and Figure 6a The carrier 340 may include a guide portion 342, at least a portion of which is fastened to a receiving portion 330 formed in the camera housing 320. In an embodiment, the carrier 340 may be positioned relative to the camera housing 320 about the receiving portion 330 around a first axis (e.g., a pitch axis and / or...). Figure 4c The Y-axis), the second axis (e.g., the yaw axis and / or Figure 4c The X-axis and / or a third axis (e.g., the roll axis and / or the y-axis) are also important axes for navigating the y-axis. Figure 4c The Z-axis is rotated to perform an optical image stabilizer (OIS) function to correct shake in the camera module 300.
[0095] According to the embodiments, such as Figure 4a , Figure 4b and Figure 4cAs shown, the camera module 300 may be configured such that the first OIS actuator 410, the second OIS actuator 420, and / or the third OIS actuator 430 are controlled by the processor 120 to correct image jitter (e.g., perform optical image stabilization (OIS) functionality). In an embodiment, the first OIS actuator 410 may include a first OIS magnet 411 (e.g., a magnet) and a first OIS coil 412, wherein the first OIS magnet 411 is disposed on the carrier 340 facing a first portion 321 of the camera housing 320, and the first OIS coil 412 is disposed in the first portion 321 of the camera housing 320 such that at least a portion thereof faces the first OIS magnet 411 and is connected to the flexible printed circuit board 460. In one embodiment, the second OIS actuator 420 may include a second OIS magnet 421 (e.g., a magnet) and a second OIS coil 422, wherein the second OIS magnet 421 is disposed on the carrier 340 facing the second portion 322 of the camera housing 320, and the second OIS coil 422 is disposed in the second portion 322 of the camera housing 320 such that at least a portion thereof faces the second OIS magnet 421 and is connected to the flexible printed circuit board 460. In another embodiment, the third OIS actuator 430 may include a third OIS magnet 431 (e.g., a magnet) (e.g., Figure 4a The third OIS magnet 431 and the third OIS coil 432 are disposed on the carrier 340 facing the third portion 323 of the camera housing 320, and the third OIS coil 432 is disposed in the third portion 323 of the camera housing 320 such that at least a portion of it faces the third OIS magnet 431 and is connected to the flexible printed circuit board 460. Additionally, the first OIS actuator 410, the second OIS actuator 420, and the third OIS actuator 430 can be modified to various elements capable of rotating the carrier 340 relative to the image sensor 370.
[0096] According to an embodiment, the processor 120 can control the carrier 340 to revolve around a first axis relative to the image sensor 370 (e.g., Figure 4c The first axis in the middle), the second axis (for example, Figure 4c The second axis) and / or the third axis (e.g., Figure 4c The third axis in the image rotates in a direction that counteracts movement (e.g., shakiness and / or hand shake) generated by the user during the shooting process using the camera module 300 of the electronic device 200. The processor 120 of the electronic device 200 can obtain the sensor module of the electronic device 200 (e.g., Figure 1The sensor module 176 in the camera module 300 detects movement information of the electronic device 200 and can operate the first OIS actuator 410, the second OIS actuator 420, and / or the third OIS actuator 430 based on the movement information. For example, based on the movement information of the electronic device 200, the first OIS actuator 410, the second OIS actuator 420, and / or the third OIS actuator 430 can be operated to rotate the carrier 340 relative to the image sensor 370 of the camera module 300 about a first axis, a second axis, and / or a third axis by a predetermined angle. This improves the quality of the image obtained by the camera module 300. For example, during the capture of video of a subject or during the capture of an image of a subject, camera module 300 shake can be suppressed to improve image quality.
[0097] In the embodiments, reference is made to Figure 3b , Figure 4a , Figure 4b and Figure 4c The carrier 340 may include a first surface 3401 facing a first portion 321 of the camera housing 320, a second surface 3402 facing a second portion 322 of the camera housing 320, and a third surface 3403 facing a third portion 323 of the camera housing 320. In an embodiment, the second surface 3402 and the third surface 3403 may be substantially parallel to each other. In an embodiment, the first surface 3401 may be substantially perpendicular to the second surface 3402 and the third surface 3403. In an embodiment, a first OIS magnet 411 may be disposed on the first surface 3401 of the carrier 340 to face a first OIS coil 412 disposed in the first portion 321 of the camera housing 320. In an embodiment, a second OIS magnet 421 may be disposed on the second surface 3402 of the carrier 340 to face a second OIS coil 422 disposed in the second portion 322 of the camera housing 320. In one embodiment, a third OIS magnet 431 may be disposed on a third surface 3403 of the carrier 340, facing a third OIS coil 432 disposed in a third portion 323 of the camera housing 320. In another embodiment, a first OIS magnet 411 and a second OIS magnet 421 may be arranged on mutually perpendicular surfaces (e.g., first surface 3401 and second surface 3402) of the carrier 340, and thus located substantially perpendicular to each other. In yet another embodiment, the first OIS magnet 411 and the third OIS magnet 431 may be arranged on mutually perpendicular surfaces (e.g., first surface 3401 and third surface 3403) of the carrier 340, and thus located substantially perpendicular to each other.
[0098] According to the embodiments, such as Figure 4c And the description below Figure 5aAs shown, by means of electromagnetic force acting on the first OIS actuator 410 (e.g., the first OIS magnet 411 and the first OIS coil 412), the carrier 340 and the reflective member R can be positioned relative to the image sensor 370 around a first axis (e.g., Figure 4c (in the pitch axis and / or Y axis) rotation (e.g., in Figure 4c (Rotation in the XZ plane). In an embodiment, the carrier 340 and the reflective member R can rotate relative to the image sensor 370 around a second axis (e.g., by an electromagnetic force acting on the second OIS actuator 420 (e.g., the second OIS magnet 421 and the second OIS coil 422)). Figure 4c The yaw axis and / or X-axis in the rotation (e.g., in Figure 4c (Rotation on the YZ plane). In an embodiment, the carrier 340 and the reflective member R can rotate relative to the image sensor 370 around a third axis (e.g., by electromagnetic force acting on the third OIS actuator 430 (e.g., the third OIS magnet 431 and the third OIS coil 432). Figure 4c Rotation of the roll axis and / or Z-axis (e.g., in the roll axis and / or Z-axis) Figure 4c (Rotation on the XY plane).
[0099] In one embodiment, the carrier 340 is rotatable about a first axis, a second axis, and a third axis, which are axes of rotation, and therefore rotatable relative to the image sensor 370 and the camera housing 320. In another embodiment, the third axis may be the incident optical axis passing through the center of the incident surface S1 of the reflecting member R (e.g., Figure 12a The incident optical axis C1 in the reflection member R). The second axis can be the outgoing optical axis passing through the center of the outgoing surface S2 of the reflecting member R (e.g., the outgoing optical axis). Figure 12a The outgoing optical axis C2 in the embodiment. In this embodiment, the first axis may be the point through the intersection of the second and third axes and substantially parallel to the line of sight. Figure 4c The Y-axis is the axis of the reflective element R. In an embodiment, the intersection of the first axis, the second axis, and the third axis may be located on the reflective surface S3 of the reflective element R.
[0100] As described below, the rotation center of the reflective member R (e.g., Figure 12aThe rotation center M of the reflective member R can coincide with the reflection center of the reflective surface S3. In an embodiment, the reflection center can be the intersection of the incident optical axis C1 (e.g., the third axis) passing through the center of the incident surface S1 of the reflective member R and the exit optical axis C2 (e.g., the second axis) passing through the center of the exit surface S2 of the reflective member R. In an embodiment, the rotation center M of the reflective member R can be the rotation center M of the carrier 340 relative to the camera housing 320. In an embodiment, the rotation center M of the reflective member R can be the intersection of the first axis, the second axis, and / or the third axis. Therefore, according to embodiments of the present disclosure, when the rotation center M of the reflective member R and the reflection center of the reflective surface S3 coincide with each other, the image jitter correction error can be reduced based on the control of the first OIS actuator 410, the second OIS actuator 420, and / or the third OIS actuator 430.
[0101] As described above, the second OIS actuator 420 can be configured to rotate the carrier 340 and the reflective member R relative to the image sensor 370 about a second axis, and the third OIS actuator 430 can be configured to rotate the carrier 340 and the reflective member R relative to the image sensor 370 about a third axis. However, the invention is not limited to the above description, and various embodiments are possible. In one embodiment, the second OIS actuator 420 can be configured to rotate the carrier 340 and the reflective member R relative to the image sensor 370 about a third axis. In this case, the third OIS actuator 430 can be configured to rotate the carrier 340 and the reflective member R relative to the image sensor 370 about a second axis. In another embodiment, reference is made to the following description. Figure 6b The second OIS actuator 420 and the third OIS actuator 430 may be configured to rotate the carrier 340 and the reflective member R relative to the image sensor 370 about a third axis. For example, the second OIS actuator 420 and the third OIS actuator 430 may be configured to rotate the carrier 340 and the reflective member R relative to the image sensor 370 about a third axis. In an embodiment, the second OIS actuator 420 and the third OIS actuator 430 may be configured such that the carrier 340 and the reflective member R rotate about the same axis. For example, the second OIS actuator 420 and the third OIS actuator 430 may be configured to rotate the carrier 340 and the reflective member R relative to the image sensor 370 about a second axis.
[0102] Additionally, the first OIS actuator 410, the second OIS actuator 420, and the third OIS actuator 430 can be configured to provide various rotation axes to the carrier 340 and the reflective member R. In the following description, for ease of explanation, the second OIS actuator 420 can be configured to rotate the carrier 340 and the reflective member R about a second axis, and the third OIS actuator 430 can be configured to rotate the carrier 340 and the reflective member R about a third axis.
[0103] According to embodiments of this disclosure, either the second OIS actuator 420 or the third OIS actuator 430 may be omitted. For example, the third OIS actuator 430 may be omitted. For example, in this case, image jitter can be corrected by driving the first OIS actuator 410 to rotate the carrier 340 relative to the image sensor 370 about a first axis. Alternatively, image jitter can be corrected by driving the second OIS actuator 420 to rotate the carrier relative to the image sensor 370 about a second or third axis. The following description will be given assuming that the camera housing 320 includes all of the first OIS actuator 410, the second OIS actuator 420, and the third OIS actuator 430. However, the following description can also be applied equally to cases where one of the second OIS actuator 420 and the third OIS actuator 430 of the camera housing 320 is omitted.
[0104] According to the embodiments, such as Figure 4c And the description below Figure 5a As shown, at least one magnetic flux detection sensor 520 may be disposed at the central portion of an OIS coil (e.g., a first OIS coil 412, a second OIS coil 422, and a third OIS coil 432). In an embodiment, multiple magnetic flux detection sensors 520 may be arranged inside the OIS coil. Based on the rotation of the carrier 340, the magnetic flux detection sensor 520 may detect changes in magnetic flux value according to variations in distance from the OIS magnets (e.g., the first OIS magnet 411, the second OIS magnet 421, and the third OIS magnet 431) facing the magnetic flux detection sensor. The processor 120 may detect the changes in magnetic flux value detected by the magnetic flux detection sensor 520 to control the rotation of the carrier 340.

[0106] According to the embodiments, such as Figure 5a and Figure 5bAs shown, the carrier 340 may include a base portion 341 in which the reflective member R is disposed. In an embodiment, the base portion 341 may include a groove having a shape corresponding to the reflective member R. In an embodiment, the base portion 341 may include a first inclined surface 3411 facing the reflective surface S3 of the carrier 340. In an embodiment, the first inclined surface 3411 (e.g., Figure 12a The first inclined surface 3411 of the reflective member R can be substantially parallel to the reflective surface S3. In an embodiment, the reflective surface S3 of the reflective member R can be a surface inclined at a predetermined angle relative to the support surface 325 of the camera housing 320. The first inclined surface 3411 can be substantially parallel to the reflective surface S3, and therefore can form a predetermined angle with the support surface 325 of the camera housing 320.
[0107] According to the embodiments, such as Figure 5b , Figure 6a and Figure 6c As shown, the carrier 340 may include a guide portion 342. In an embodiment, the guide portion 342 may be formed in a direction facing the reflective surface S3 of the reflective member R (e.g., a direction opposite to the reflective surface S3 of the reflective member R). For example, the guide portion 342 may extend from the base portion 341 in a direction substantially perpendicular to the first inclined surface 3411, and may extend in a direction facing the reflective member R (e.g., a direction opposite to the reflective member R). In an embodiment, when the carrier 340 is disposed in the camera housing 320, the guide portion 342 may be formed to be inclined at a predetermined angle relative to the support surface 325 of the camera housing 320.
[0108] In one embodiment, the guide portion 342 may have at least a portion inserted into a receiving portion 330 protruding from a support surface 325 of the camera housing 320. In another embodiment, the receiving portion 330 of the camera housing 320 may include a guide groove 331 that allows the guide portion 342 to be inserted therein. Based on the guide portion 342 being secured to the guide groove 331 of the receiving portion 330, the carrier 340 can be rotated relative to the camera housing 320 about a first axis, a second axis, and / or a third axis via a first OIS actuator 410, a second OIS actuator, and / or a third OIS actuator 430.
[0109] According to the embodiments, refer to Figure 5a , Figure 5b and Figure 6cThe receiving portion 330 of the camera housing 320 may include a second inclined surface 332 corresponding to the first inclined surface 3411 of the base portion 341. In an embodiment, the reflective surface S3 of the reflective member R, the first inclined surface 3411, and the second inclined surface 332 may be substantially parallel to each other. In an embodiment, a guide groove 331 may be formed on the second inclined surface 332 of the receiving portion 330. The carrier 340 may be located in the camera housing 320 such that the guide portion 342 is disposed in the guide groove 331 of the receiving portion 330.
[0110] In an embodiment not shown in the accompanying drawings, the guide portion 342 of the carrier 340 may protrude substantially perpendicular to the support surface 325 of the camera housing 320. For example, the guide portion 342 may protrude from one surface of the carrier 340 perpendicular to the incident surface S1 of the reflecting member R. Based on this, the receiving portion 330 of the camera housing 320 may include a flat surface (not shown) substantially parallel to the support surface 325 of the camera housing 320. A guide groove 331 may be formed on the flat surface of the receiving portion 330. Based on the guide portion 342 being fastened to the guide groove 331 of the receiving portion 330, the carrier 340 may be rotatable relative to the camera housing 320. In an embodiment, the guide portion 342 of the carrier 340 may have at least a portion formed in a spherical shape, and the guide groove 331 of the camera housing 320 may be formed in a shape corresponding to the guide portion 342. In an embodiment, the carrier 340 can be rotated relative to the camera housing 320 by means of a guide structure disposed between the guide portion 342 and the guide groove 331 (e.g., OIS ball b1 and / or protrusion (not shown) formed on one of the guide portion 342 and the guide groove 331).
[0111] In one embodiment, based on the guide portion 342 being fastened to the guide groove 331 of the receiving portion 330, the carrier 340 can be rotated relative to the camera housing 320 about a first axis, a second axis, and / or a third axis via a first OIS actuator 410, a second OIS actuator, and / or a third OIS actuator 430.
[0112] As described above, the guide portion 342 of the carrier 340 and the receiving portion 330 of the camera housing 320 can be formed in various shapes so that the carrier 340 can be rotatably fastened to the camera housing 320.
[0113] According to an embodiment, a guide structure may be disposed between the camera housing 320 and the carrier 340. In an embodiment, the guide structure may be located between the guide portion 342 of the carrier 340 and the guide groove 331 of the receiving portion 330 of the camera housing 320. In an embodiment, the guide structure may guide the rotation of the carrier 340 relative to the image sensor 370 within the camera housing 320. In an embodiment, the guide structure may contact at least one of the surfaces of the guide portion 342 of the carrier 340 and the receiving portion 330 located in the guide groove 331 of the receiving portion 330 at at least three points. In this case, the guide portion 342 of the carrier 340 may rotate relative to the receiving portion 330 about at least three points within the guide groove 331 of the camera housing 320. Furthermore, since at least one of the guide portion 342 and the receiving portion 330 contacts the guide structure at at least three points, linear movement (or sliding) of the guide portion 342 of the carrier 340 within the guide groove 331 of the camera housing 320 is prevented during the rotation of the carrier 340 relative to the camera housing 320. Therefore, linear movement of the carrier 340 relative to the camera housing 320 can be prevented by the guide portion 342, and rotational movement of the carrier relative to the camera housing 320 is possible.
[0114] In the embodiments, reference is made to Figure 5b , Figure 6a and Figure 8 The guiding structure can be OIS balls b1, which serve as bearing balls. In an embodiment, at least three OIS balls b1 may be arranged between the guiding portion 342 of the carrier 340 and the guiding groove 331 of the receiving portion 330. As described below, the OIS balls b1 may contact the curved portion 333 (e.g., the first curved portion 333) of the guiding groove 331.
[0115] In one embodiment, the guide structure may be at least three protrusions formed protruding from at least one of the receiving portion 330 of the camera housing 320 or the guide portion 342 of the carrier 340. In another embodiment, the protrusions may be formed to protrude from a first curved portion 333 located within a guide groove 331 of the receiving portion 330 and contact the guide portion 342 of the carrier 340 at at least three points. In yet another embodiment, the protrusions may be formed to protrude from the guide portion 342 of the carrier 340 and contact the first curved portion 333 of the receiving portion 330 at at least three points.
[0116] As described above, the guide structure can be constructed in various ways, such as the OIS ball b1 or a protrusion integrally formed with the receiving portion 330 or the guide portion 342. For example... Figure 5b , Figure 6a , Figure 8 , Figure 9 , Figure 10a , Figure 10b As shown, the following description will be given when the guide structure is an OIS ball b1 that functions as a bearing ball. However, the following description can also be applied to the case where the guide structure is a protrusion.
[0117] According to the embodiments, such as Figure 5a , Figure 5b and Figure 6c As shown, the receiving portion 330 of the camera housing 320 may include a planar portion 334 and a first curved portion 333 located in the guide groove 331. In an embodiment, the planar portion 334 may be substantially parallel to the first inclined surface 3411 of the support member 340 and the reflective surface S3 of the reflective member R. In an embodiment, the first curved portion 333 may surround the planar portion 334 in the guide groove 331. In an embodiment, the first curved portion 333 may be formed in the guide groove 331 and is formed to have a predetermined curvature.
[0118] In an embodiment, the first curved portion 333 may be the portion of the receiving portion 330 that contacts the guide structure. For example, see reference... Figure 8 The OIS ball b1, serving as a guide structure, can be arranged between the guide portion 342 of the carrier 340 and the first curved portion 333 of the receiving portion 330. In an embodiment, as described below... Figure 10a As shown, the OIS ball b1 can be placed in a receiving groove 344 formed in the guide portion 342 of the carrier 340. In an embodiment, the receiving groove 344 can be formed in a second curved portion 345 of the guide portion 342, which has a predetermined curvature. In an embodiment, with the guide portion 342 of the carrier 340 fastened to the guide groove 331 of the camera housing 320, the second curved portion 345 can face the first curved portion 333.
[0119] Based on the rotation of the carrier 340 relative to the camera housing 320 about a first axis, a second axis, and / or a third axis, the OIS ball b1 can move along the first curved portion 333 of the receiving portion 330 while located in the receiving groove 344 of the guide portion 342, so as to guide the rotation of the carrier 340 relative to the camera housing 320.
[0120] According to the embodiments, such as Figure 5b and Figure 6a As shown, the first ball bearing cap 360A (e.g., Figures 11a to 11d The first ball cap 360A is coupled to the guide portion 342 of the carrier 340. In an embodiment, the first ball cap 360A prevents the OIS ball b1 disposed in the receiving groove 344 of the guide portion 342 from separating from the receiving groove 344. In an embodiment, the first ball cap 360A may include an opening 361A for receiving the portion of the OIS ball b1.
[0121] According to the embodiments, such as Figure 6c and Figure 8 And the following description Figure 12a As shown, the first curved portion 333 of the receiving portion 330 may include a flat region (e.g., a first flat region 335). In an embodiment, the flat region 335 may be formed at the lowermost end of the first curved portion 333 adjacent to the support surface 325 of the camera housing 320. In an embodiment, the OIS ball b1 may be located in the first curved portion 333 other than the flat region 335. In an embodiment, the guide portion 342 of the carrier 340 may include a flat region (e.g., a second flat region) a portion of which corresponds to the flat region 335 of the receiving portion 330.
[0122] In the embodiments, reference is made to Figure 6c and Figure 8 And the following description Figure 12a The first flat region 335 may be substantially parallel to the support surface 325 of the camera housing 320. In an embodiment, compared to the case where the first flat region 335 is not formed, when the first flat region 335 is formed at the lowermost end of the first curved portion 333 of the receiving portion 330 and when the guide portion 342 of the carrier 340 is fastened to the receiving portion 330, the height of the carrier 340 from the support surface 325 of the camera housing 320 (e.g., referring to...) Figure 12a The length in the Z-axis direction can be reduced. For example, compared to the case where the first flat region 335 is not formed, when the first flat region 335 is formed in the guide groove 331, the guide portion 342 can be in the guide groove 331 in reference... Figure 12a The Z-axis direction is lowered, and thus it is positioned in the guide groove 331. Therefore, compared to the case where the first flat area 335 is not formed in the guide groove 331, the height H of the support member 340 occupying the interior of the camera housing 320 (e.g., referring to...) is... Figure 12a The length in the Z-axis direction can be reduced.
[0123] According to the embodiments, such as Figure 5b , Figure 6a , Figure 6b , Figure 7a , Figure 7b and Figure 7cAs shown, a first attracting magnet 511 may be disposed in the receiving portion 330 of the camera housing 320. In an embodiment, the first attracting magnet 511 may be located in the receiving portion 330 and disposed in a planar portion 334 substantially parallel to the first inclined surface 3411. A second attracting magnet 512 may be disposed on a surface of a guide portion 342 inserted into the receiving portion 330. In an embodiment, an attractive force may be applied between the first attracting magnet 511 and the second attracting magnet 512. The guide portion 342 of the carrier 340 and the receiving portion 330 of the camera housing 320 may be pulled toward each other by the attractive force acting between the first attracting magnet 511 and the second attracting magnet 512. Based on this, the guide portion 342 of the carrier 340 and the receiving portion 330 of the camera housing 320 may be kept in point contact with the guide structure (e.g., OIS ball b1 or protrusion).
[0124] According to embodiments, the first magnetic attractor 511 and the second magnetic attractor 512 can be constructed in various shapes. In an embodiment, reference is made to... Figure 6c The first attracting magnet 511 may include two magnets having a straight shape. In this case, as... Figure 6a , Figure 6b and Figure 7a As shown, the second attracting magnet 512 may include two magnets having a straight shape to correspond to the first attracting magnet 511. In an embodiment, reference is made to... Figure 7a The magnets constituting the first attracting magnet 511 and the second attracting magnet 512 may have a width and height of approximately 2 mm and a thickness of approximately 0.3 mm. In an embodiment, referring to... Figure 7b The first attracting magnet 511 and the second attracting magnet 512 may be formed as magnets with at least a portion having a semi-circular shape. In an embodiment, referring to... Figure 7c The first attracting magnet 511 and the second attracting magnet 512 can be magnets or metal sheets (e.g., magnetic yokes). For example, the first attracting magnet 511 disposed in the camera housing 320 can be a metal sheet that exerts an attractive force on the second attracting magnet 512. In an embodiment, the first attracting magnet 511 can be formed as a cross-shaped magnet. In this case, the second attracting magnet 512 can be formed as a cross-shaped magnet to correspond to the first attracting magnet 511. Alternatively, the first attracting magnet 511 and the second attracting magnet 512 can be formed in various shapes.
[0125] In an embodiment, when the carrier 340 is relative to the camera housing 320 via the first OIS actuator 410, the second OIS actuator, and / or the third OIS actuator 430, except around the first axis (e.g., Figure 5a The Y-axis), the second axis (e.g., Figure 5a The X-axis and / or the third axis (e.g., the X-axis) and / or the third axis (e.g., Figure 5a When the carrier 340 is moved in an unexpected direction other than the Z-axis (in the image), it can be returned to its default position by the attraction between the first attracting magnet 511 and the second attracting magnet 512. The “default position” of the carrier 340 can be the original state in which the carrier is assembled to the camera housing 320, and can be the state in which the carrier does not rotate about the first axis, second axis, and / or third axis. For example, the default position can be the position of the carrier 340 when it is not tilted relative to the camera housing 320, and the position of the carrier relative to the camera housing 320 when the OIS actuators (e.g., the first OIS actuator 410, the second OIS actuator 420, and / or the third OIS actuator 430) are not actuated. In the embodiment, reference is made to the description above. Figure 4c When the carrier 340 is in the default position, the reflector R can be configured such that the incident surface S1 is substantially perpendicular to the third axis and the exit surface S2 is substantially perpendicular to the second axis.
[0126] In this embodiment, when the power to the camera module 300 is turned off, the carrier 340 may return to its default position relative to the camera housing 320 and / or may be held in its default position based on the attractive force acting between the first attracting magnet 511 and the second attracting magnet 512. For example, when the power to the camera module 300 is turned off while the carrier 340 is rotating relative to the camera housing 320 about a first axis, a second axis, and / or a third axis, the carrier 340 may return to its default position relative to the camera housing 320 by the attractive force acting between the first attracting magnet 511 and the second attracting magnet 512.

Figure 11c and Figure 11d This is a side view of a first ball bearing cover according to an embodiment of the present disclosure. Figure 12a This is a view showing the state in which the guide portion of the carrier according to an embodiment of the present disclosure is fastened to the receiving portion of the camera housing. Figure 12b It is shown Figure 12a An enlarged view showing the arrangement of the first ball bearing cap, OIS balls, and guide portion. Figure 13This is a view showing the state in which a lens module according to an embodiment of the present disclosure is arranged on the incident and exit surfaces of a reflecting member.
[0128] According to the embodiments, such as Figure 9 As shown, the reflector actuator may include a reflective member R, a carrier 340, a first OIS magnet 411, a second OIS magnet 421, a third OIS magnet 431, an OIS ball b1, a first ball cover 360A, and a second attracting magnet 512. At least one of the above components may be omitted, or at least one other component may be added.
[0129] According to the embodiments, such as Figure 10a and Figure 10b As shown, the guide portion 342 of the carrier 340 may include a curved portion (e.g., a second curved portion 345) corresponding to the first curved portion 333 of the receiving portion 330 of the camera housing 320. In an embodiment, the second curved portion 345 of the guide portion 342 may be formed to have substantially the same curvature as the first curved portion 333 of the receiving portion 330.
[0130] According to the embodiments, such as Figure 10a and Figure 10b As shown, the OIS ball b1 can be disposed in a receiving groove 344 formed in the guide portion 342 of the carrier 340. In an embodiment, at least a portion of the receiving groove 344 can be formed in a second curved portion 345 formed in the guide portion 342 having a predetermined curvature. In an embodiment, with the guide portion 342 of the carrier 340 fastened to the guide groove 331 of the camera housing 320, the second curved portion 345 can face the first curved portion 333. In an embodiment, the OIS ball b1 can contact one of the surfaces of the guide portion 342 located in the receiving groove 344. In an embodiment, based on the rotation of the guide portion 342 of the carrier 340 relative to the receiving portion 330 of the camera housing 320, the OIS ball b1 can perform a rolling motion in the receiving groove 344 while in contact with the first curved portion 333.
[0131] According to the embodiments, such as Figure 10a and Figure 10bAs shown, the receiving grooves 344 can be formed at equal intervals. For example, when three OIS balls b1 are arranged between the guide portion 342 and the receiving portion 330, the three receiving grooves 344 can be formed at equal intervals. For example, adjacent receiving grooves 344 can be formed at equal angles of 120 degrees along a virtual circle. Therefore, multiple OIS balls b1 can be located in the guide portion 342 at equal intervals. For example, adjacent OIS balls b1 can be placed at equal angles of 120 degrees. Therefore, based on the multiple OIS balls b1 being arranged at equal intervals, the receiving portion 330 of the camera housing 320 can stably contact the OIS balls b1 at three points.
[0132] However, the number of OIS balls b1 described above is merely an example, and the number of OIS balls b1 can exceed three. In this case, the gap between the receiving grooves 344 and the gap between the OIS balls b1 can be reduced. For example, adjacent receiving grooves 344 can be arranged on the guide portion 342 at equal angles of less than 120 degrees along a virtual circle. Therefore, adjacent OIS balls b1 can be arranged at equal angles of less than 120 degrees along a virtual circle.
[0133] According to the embodiments, such as Figure 9 , Figure 10b , Figure 11a , Figure 11b and Figure 11c As shown, the OIS ball b1 can be held in a receiving groove 344 of the guide portion 342 by means of a first ball cap 360A coupled to the guide portion 342. In an embodiment, the first ball cap 360A prevents the OIS ball b1 from separating from the receiving groove 344 of the guide portion 342. In an embodiment, the first ball cap 360A may include an opening 361A for receiving a portion of the OIS ball b1. In an embodiment, the OIS ball b1 can contact a first curved portion 333 of the receiving portion 330 with its portion received in the opening 361A of the first ball cap 360A to guide the rotation of the carrier 340 relative to the camera housing 320.
[0134] In an embodiment, the opening 361A formed in the first ball cap 360A may be based on the number of OIS balls b1. In an embodiment, referring to... Figure 12b The opening 361A formed in the first ball cover 360A can be formed to have a size smaller than that of the OIS ball b1. For example, the diameter D2 of each of the openings 361A formed in the first ball cover 360A can be smaller than the diameter D1 of each of the OIS balls b1. Therefore, the OIS balls b1 can pass through the openings 361A formed in the first ball cover 360A without separating from the receiving groove 344.
[0135] In an embodiment, the first ball bearing cap 360A may be formed to have dimensions that allow the first ball bearing cap to be disposed in a guide groove 331 of the camera housing 320. For example, Figure 8 The diameter D'1 of the curved portion 333 shown can be formed to a size that allows the first ball bearing cap 360A to be accommodated therein. The diameter D'1 of the curved portion 333 can be the diameter of the virtual circle corresponding to the curved portion 333 when the planar portion 334 is viewed vertically.
[0136] In the embodiments, reference is made to Figure 12a and Figure 13 A virtual circle having a radius equal to the distance from the rotation center M of the reflective member R to the outer surface of the first ball bearing cover 360A can be formed with a diameter D'2 of approximately 5 mm to 7 mm. For example, the diameter D'2 of the virtual circle having a radius equal to the distance from the rotation center M of the reflective member R to the outer surface of the first ball bearing cover 360A can be 5.8 mm.
[0137] In the embodiments, reference is made to Figure 11c The height L of the first ball cover 360A can be formed at a ratio of approximately 22% to 30% of the diameter D'2 of the virtual circle, which has a radius equal to the distance from the rotation center M to the outer surface of the first ball cover 360A. In an embodiment, the height L of the first ball cover 360A can be approximately 1.65 mm.
[0138] The values and shapes of the first ball cover 360A described above are merely examples, and the first ball cover 360A may be formed in various shapes such that the OIS ball b1 can be placed between the guide portion 342 and the first ball cover 360A.
[0139] According to the embodiments, such as Figure 10a and Figure 10bAs shown, a first ball cap 360A is coupled to a guide portion 342 of a carrier 340. In an embodiment, the first ball cap 360A and the guide portion 342 may include a fastening structure. In an embodiment, the guide portion 342 may include a fastening portion 346 projecting from one of its surfaces. The first ball cap 360A may include a fastening groove 363A in which the fastening portion 346 is inserted. In an embodiment, the fastening groove 363A may be formed on a coupling portion 362A that contacts the guide portion 342. When the fastening portion 346 of the guide portion 342 is coupled to the fastening groove 363A, the first ball cap 360A may be secured to the guide portion 342. In an embodiment, the coupling portion 362A may press against the guide portion 342 to increase the coupling force of the ball cap 360A relative to the guide portion 342. The method described above for coupling the first ball cap 360A and the guide portion 342 is merely an example, and the first ball cap 360A and the guide portion 342 can be coupled in various ways. For example, the first ball cap 360A can be fastened to the guide portion 342 by a hook fastening method or a screw fastening method.
[0140] In this embodiment, when a lubricant (e.g., grease) is applied to the interior of the receiving groove 344, the friction between the OIS ball b1 and the inner surface of the receiving groove 344 is reduced. In this embodiment, the OIS ball b1 can remain attached to the receiving groove 344 due to the viscosity of the lubricant. Therefore, even if the first ball cap 360A is not coupled to the guide portion 342, the OIS ball b1 will not separate from the receiving groove 344. Based on this, with the first ball cap 360A omitted and the OIS ball b1 arranged in the receiving groove 344 of the guide portion 342, the guide portion 342 of the carrier 340 can be fastened to the receiving portion 330 of the camera housing 320.
[0141] According to the embodiments, such as Figure 12aAs shown, when the guide portion 342 of the carrier 340 is fastened to the receiving portion 330 of the camera housing 320, the reflective surface S3 of the reflective member R and the second inclined surface 332 of the receiving portion 330 can be substantially parallel to each other. When the guide portion 342 of the carrier 340 is fastened to the receiving portion 330 of the camera housing 320, the rotation center M of the reflective member R can coincide with the reflection center of the reflective surface S3. In an embodiment, the reflection center can be the intersection of the incident optical axis C1 passing through the center of the incident surface S1 of the reflective member R and the outgoing optical axis C2 passing through the center of the outgoing surface S2 of the reflective member R. In an embodiment, the rotation center M of the reflective member R can be the rotation center M of the carrier 340 relative to the camera housing 320. In an embodiment, the rotation center M of the reflective member R can be the intersection of a first axis, a second axis, and / or a third axis. Therefore, according to embodiments of this disclosure, since the rotation center M of the reflective member R and the reflection center of the reflective surface S3 coincide with each other, the error of image jitter correction can be reduced based on the control of the first OIS actuator 410, the second OIS actuator 420 and / or the third OIS actuator 430.
[0142] According to the embodiments, such as Figure 12a and Figure 13 As shown, a virtual circle having a radius equal to the distance from the rotation center M of the reflective member R to the first curved portion 333 of the receiving portion 330 that contacts the OIS ball b1 can be formed with a diameter D'3 of approximately 5 mm to 7 mm. Alternatively, if defined differently, the diameter of the virtual circle having a radius equal to the distance from the rotation center M of the reflective member R to the point where the OIS ball b1 contacts the first curved portion 333 of the receiving portion 330 can be the diameter D'3. In an embodiment, the diameter D'3 of the virtual circle can be approximately 6 mm. The diameter D1 of each of the OIS balls b1 can be formed to be 10% to 20% of the diameter D'3 of the virtual circle, the radius of which is the distance from the rotation center M of the reflective member R to the first curved portion 333 of the receiving portion 330 that contacts the OIS ball b1. In an embodiment, each of the OIS balls b1 can be formed with a diameter D1 of approximately 0.7 mm to 1.1 mm. For example, the diameter D1 of each of the OIS balls b1 can be approximately 1 mm. In an embodiment, the distance R' from the rotation center M of the reflective member R to the center of the OIS ball b1 can be approximately 2.15 mm to 2.95 mm.

In an embodiment, reference is made to... Figure 12a and Figure 13 The fourth axis (for example, Figure 12a and Figure 13 The A-axis in the diagram can be an axis substantially parallel to the short side of the reflective surface S3 of the reflective member R. In an embodiment, each of the second OIS actuator 420 and the third OIS actuator 430 can be controlled to rotate the carrier 340 relative to the image sensor 370 about a fourth axis to correct image jitter.

In an embodiment, the receiving groove 336 can be formed in a guide groove 331 of the receiving portion 330. For example, at least a portion of the receiving groove 336 can be formed in a first curved portion 333 of the receiving portion 330 (e.g., the first curved portion 333). In an embodiment, the OIS ball b1 can contact a surface of the receiving portion 330 located in the receiving groove 336. In an embodiment, the OIS ball b1 can be arranged in the receiving groove 336 of the receiving portion 330 to surround a first attracting magnet 511 disposed in the guide groove 331.
[0148] According to the embodiments, such as Figure 15a and Figure 15b As shown, receiving grooves 336 can be formed in guide grooves 331 at equal intervals. Therefore, a plurality of OIS balls b1 can be located in receiving portion 330 at equal intervals. Therefore, based on the plurality of OIS balls b1 being arranged at equal intervals, the guide portion 342 of the carrier 340 can stably contact the OIS balls b1 at at least three points.
[0149] According to the embodiments, such as Figures 14a to 15b As shown, the second ball bearing cover 360B (for example, Figure 11a The first ball bearing cap 360A is coupled to the receiving portion 330 of the camera housing 320. The OIS ball b1 can be held in a receiving groove 336 formed in the receiving portion 330 by a second ball bearing cap 360B coupled to the receiving portion 330. In an embodiment, at least a portion of the second ball bearing cap 360B may be disposed on a second inclined surface 332 of the receiving portion 330. In an embodiment, the second ball bearing cap 360B may include an opening 361B for receiving a portion of the OIS ball b1. In an embodiment, the OIS ball b1 can contact the guide portion 342 of the carrier 340 with its portion received in the opening 361B of the second ball bearing cap 360B to guide rotation of the carrier 340 relative to the camera housing 320.
[0150] In the embodiments, reference is made to Figure 15b and Figure 15c The opening 361B of the second ball cover 360B can be formed in an open shape. For example, the opening 361B can be in the shape of an open surface facing the guide groove 331 on which the first attracting magnet 511 is disposed.
[0151] According to the embodiments, such as Figure 15b and Figure 15c As shown, the second ball cap 360B and the receiving portion 330 may include a fastening structure. In an embodiment, the receiving portion 330 may include a fastening portion 337 projecting from one of its surfaces. The second ball cap 360B may include a fastening groove 363B in which the fastening portion 337 is inserted. In an embodiment, the fastening groove 363B may be formed on a coupling portion 362B that contacts the guide portion 342. When the fastening portion 337 of the receiving portion 330 is coupled to the fastening groove 363B, the second ball cap 360B may be secured to the receiving portion 330. In an embodiment, the coupling portion 362B may press against the guide portion 342 to increase the coupling force of the ball cap 360B relative to the guide portion 342. The methods described above for coupling the second ball cap 360B and the receiving portion 330 are merely examples, and the second ball cap 360B and the receiving portion 330 may be coupled in various ways. For example, the second ball cap 360B can be coupled to the receiving portion 330 by hook fastening or screw fastening.
[0152] Figure 16a and Figure 16b This is a view showing the relationship between the magnetic flux detection sensor disposed inside the OIS coil and the OIS magnet disposed on the carrier 340.
[0153] According to an embodiment, at least one magnetic flux detection sensor 520 may be disposed at the central portion of an OIS coil (e.g., a first OIS coil 412, a second OIS coil 422, or a third OIS coil 432). In another embodiment, multiple magnetic flux detection sensors may be arranged inside the OIS coil.
[0154] In the embodiments, reference is made to Figure 16a and Figure 16bAt least two magnetic flux detection sensors 521 and 522 may be arranged inside the second OIS coil 422. In an embodiment, the magnetic flux detection sensors 521 and 522 may be arranged inside the second OIS coil 422 to be symmetrical about a first axis and to face the second OIS magnet 421. Based on the rotation of the carrier 340, the magnetic flux detection sensors 521 and 522 can detect changes in the magnetic flux value according to changes in distance from the second OIS magnet 421. Because multiple magnetic flux detection sensors 521 and 522 are provided, the processor can more clearly identify changes in the position of the carrier 340 compared to the case of providing only one magnetic flux detection sensor. Therefore, control of the carrier 340 can be performed more accurately.
[0155] The aforementioned plurality of magnetic flux detection sensors (not shown) (e.g., magnetic flux detection sensors 521 and 522) may be arranged inside the first OIS coil 412. Based on the rotation of the carrier 340, the magnetic flux detection sensors can detect changes in the magnetic flux value according to changes in distance from the first OIS magnet 411. Similarly, a plurality of magnetic flux detection sensors (not shown) (e.g., magnetic flux detection sensors 521 and 522) may be arranged inside the third OIS coil 432. Based on the rotation of the carrier 340, the magnetic flux detection sensors can detect changes in the magnetic flux value according to changes in distance from the third OIS magnet 431.
[0156] Figure 17a and Figure 17b This is a view showing the relationship between a second OIS magnet according to an embodiment of the present disclosure and a plurality of metal sheets arranged to face different poles of the second OIS magnet disposed on the carrier 340. Figure 18a and Figure 18b This is a view showing the relationship between a third OIS magnet according to an embodiment of the present disclosure and a plurality of metal sheets arranged to face different poles of the third OIS magnet disposed on the carrier 340.
[0157] According to the embodiments, such as Figure 17a and Figure 17b As shown, a plurality of metal plates 531 and 532 facing the second OIS magnet 421 can be arranged on the camera housing 320 such that the limiting support member 340 is positioned relative to the camera housing 320 around a second axis (e.g., Figure 4c The second axis and / or Figure 17aRotation along the X-axis. In an embodiment, the plurality of metal plates 531 and 532 may include a first metal plate 531 and a second metal plate 532. In an embodiment, the first metal plate 531 and the second metal plate 532 may respectively face different poles of the second OIS magnet 421. In an embodiment, the first metal plate 531 and the second metal plate 532 may be located on a radius of rotation centered on the second axis having the carrier 340. In an embodiment, when the carrier 340 rotates relative to the camera housing 320 about the second axis, the carrier 340 may be returned to its original position by the attractive forces acting between the plurality of metal plates 531 and 532 and the second OIS magnet 421.
[0158] According to the embodiments, such as Figure 18a and Figure 18b As shown, a plurality of metal plates 541 and 542 facing the third OIS magnet 431 can be arranged on the camera housing 320 such that the limiting support member 340 is positioned relative to the camera housing 320 around a third axis (e.g., Figure 4c The third axis and / or Figure 18a Rotation along the Z-axis. In an embodiment, the plurality of metal plates 541 and 542 may include a third metal plate 541 and a fourth metal plate 542. In an embodiment, the third metal plate 541 and the fourth metal plate 542 may respectively face different poles of the third OIS magnet 431. In an embodiment, the third metal plate 541 and the fourth metal plate 542 may be located on a radius of rotation centered on the third axis having the carrier 340. In an embodiment, when the carrier 340 rotates about the third axis relative to the camera housing 320, the carrier 340 may be returned to its original position by the attractive forces acting between the plurality of metal plates 541 and 542 and the third OIS magnet 431.
[0159] Although passed Figures 17a to 18b The described structure for limiting the rotation of the support member 340 relative to the camera housing 320 about the second axis and / or the third axis is based on Figure 4c and Figure 6a The second actuator 420 and the third actuator 430 shown are illustrated, but are not limited thereto. In embodiments, structures that restrict the rotation of the carrier 340 relative to the camera housing 320 about a second axis and / or a third axis can also be applied. Figure 6b The second actuator 420 and the third actuator 430 are shown. For example, Figure 6b The metal sheet (not shown) facing the second OIS magnet 421 and the metal sheet (not shown) facing the third OIS magnet 431 may have the same characteristics as... Figure 18aThe third metal sheet 541 and the fourth metal sheet 542 shown are arranged in the same manner. For example, the metal sheets can be arranged to face the N pole and S pole of the second OIS magnet 421, respectively, to exert an attractive force on the second OIS magnet 421. Furthermore, different metal sheets can be arranged to face the N pole and S pole of the third OIS magnet 431, respectively, to exert an attractive force on the third OIS magnet 431. Therefore, the rotation of the carrier 340 relative to the camera housing 320 about a third axis can be restricted.
[0160] In this embodiment, the structure that restricts the rotation of the carrier 340 relative to the camera housing 320 about the first axis can also be applied. Figure 4c , Figure 6a and Figure 6b The first actuator 410 is shown. For example, metal sheets (not shown) may be arranged to face the N and S poles of the first OIS magnet 411, respectively, such that an attractive force is applied between them. Therefore, when the carrier 340 rotates relative to the camera housing 320 about the first axis, the carrier 340 can be returned to its original position by the attractive force acting between the plurality of metal sheets and the first OIS magnet 411. Thus, the rotation of the carrier 340 relative to the camera housing 320 about the first axis can be limited.
[0161] Figure 19a and Figure 19b This is a view showing a second OIS actuator configured to rotate a carrier about an axis tilted relative to a support surface of the camera housing, according to an embodiment of the present disclosure.
[0162] According to the embodiments, as described above Figure 12a and Figure 13 as well as Figure 19a As shown, when correcting image jitter, it can be done around the fourth axis (e.g., Figure 12a Axis A in Figure 13 The support 340 is rotated relative to the image sensor 370 (axis A in Figure 19 and / or axis A in Figure 19) to correct image jitter. In an embodiment, reference is made to... Figure 12a , Figure 13 and Figure 19a The fourth axis can be an axis substantially parallel to the short side of the reflective surface S3 of the reflective member R. In an embodiment, the tilt axis A and the reflective surface S3 can be tilted at approximately 45 degrees relative to the support surface 325 of the camera housing 320. In an embodiment, the processor 120 can control each of the second OIS actuator 420 and the third OIS actuator 430 to cause the carrier 340 to surround the fourth axis (e.g., ...) relative to the image sensor 370. Figure 12a and Figure 13 Rotate axis A in order to correct image jitter.
[0163] According to the embodiments, such as Figure 19aand Figure 19b As shown, the second OIS actuator 420 can be configured to be tilted relative to the carrier 340 and the camera housing 320, such that the carrier 340 is rotatable about a fourth axis relative to the image sensor 370. In an embodiment, the second OIS magnet 421 may be tilted and disposed on the second surface 3402 of the carrier 340. For example, as Figure 19b As shown, a second OIS magnet 421 may be disposed on a second surface 3402 of a carrier 340, such that the plurality of magnets 421a and 421b constituting the second OIS magnet 421 are substantially parallel to the fourth axis. In an embodiment, the plurality of magnets 421a and 421b constituting the second OIS magnet 421 may be symmetrical about the fourth axis, but are not limited thereto. In an embodiment, a second OIS coil 422 may be disposed obliquely in a second portion 322 of a camera housing 320 so as to face the second OIS magnet 421. For example, the second OIS coil 422 may be disposed obliquely in a second portion 322 so as to be symmetrical about the fourth axis. In an embodiment, this configuration may also be applied to a third OIS magnet 430.
[0164] Camera module 180 or 300 can achieve high magnification by using the refraction of light. For example, camera module 180 or 300 may include a reflective member R such as a prism or mirror. Light incident on the reflective member R can be reflected or refracted, and the light path can be refracted, so that the light can be transmitted to image sensor 370.
[0165] The camera module 180 using the reflective member R may have a form in which a ball guide portion (not shown), an intermediate guide portion (not shown), a reflector actuator, a lens drive portion 310, and an image sensor 370 are arranged sequentially inside the camera housing 320.
[0166] Additionally, the reflector actuator may include a reflective member R and a carrier (not shown). To correct for image jitter caused by hand tremors in the image formed on the image sensor 370, the reflective member R may be tilted relative to the image sensor 370. For example, the carrier on which the reflective member R is disposed may be driven by an actuator (e.g., a coil and a magnet) (e.g., a first OIS actuator 410, a second OIS actuator 420, and / or a third OIS actuator 430) relative to the image sensor 370 around a first axis (e.g., a pitch axis or...). Figure 4c The Y-axis) and the second axis (yaw axis) Figure 4c The X-axis or the third axis (roll axis, for example, Figure 4c The intermediate guide portion can rotate about a first axis relative to the image sensor 370 via an actuator. The carrier can rotate together with the intermediate guide portion in the same direction as the rotation of the intermediate guide portion.
[0167] Additionally, the intermediate guide portion can be a structure used to guide the rotation of the carrier. For example, if the carrier is designed to rotate about a second axis, the intermediate guide portion can guide the rotation of the carrier so that the carrier does not rotate about a third axis.
[0168] Similarly, the ball guide portion can be a configuration for guiding the rotation of the intermediate guide portion. For example, in the case where the intermediate guide portion is designed to rotate about a first axis different from the rotation axis (e.g., the second axis) of the carrier, the ball guide portion can guide the rotation of the intermediate guide portion so that the intermediate guide portion does not rotate about the second axis.
[0169] The aforementioned structure of the camera module 180 may include an intermediate guide portion for guiding the rotation of the carrier and a ball guide portion for guiding the rotation of the intermediate guide portion. Even if the arrangement of the carrier, intermediate guide portion, and ball guide portion is optimized, there may still be limitations on reducing the size of the camera module 180 because one of the components must inevitably be omitted. Furthermore, the more components constituting the camera module 180, the more complex the assembly process becomes. Therefore, its production cost may increase.
