The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0057] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)).

According to one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the selected at least one antenna. According to some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0059] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0060] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0061] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In one embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

Electronic devices according to the embodiments disclosed in this document are not limited to the aforementioned devices.

[0063] The embodiments of this document and the terminology used herein are not intended to limit the technical features described in this document to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In this document, each of the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among those phrases, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used merely to distinguish one component from another, and do not limit the components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as "coupled" or "connected" to another (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0064] The term "module" used in the embodiments of this document may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0065] Embodiments of the present document may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (101)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0066] According to one embodiment, the method according to the embodiments disclosed in the present document may be provided as included in a computer program product.

In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to embodiments, operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.

[0068] FIG. 2 is a block diagram illustrating a camera module according to one embodiment.

[0069] Referring to FIG. 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). The lens assembly (210) may collect light emitted from a subject that is a target of image capturing. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera module (180) may include a plurality of lens assemblies (210). In this case, the camera module (180) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of 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. A lens assembly (210) may include, for example, a wide-angle lens or a telephoto lens.

[0070] The flash (220) can emit light used to enhance light emitted or reflected from a subject. According to one embodiment, the flash (220) can include one or more light-emitting diodes (e.g., red-green-blue (RGB) LED, white LED, infrared LED, or ultraviolet LED), or a xenon lamp. The image sensor (230) can acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through the lens assembly (210) into an electrical signal. According to one embodiment, the image sensor (230) can include one image sensor selected from among image sensors having different properties, such as, for example, an RGB sensor, a black and white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same property, or a plurality of image sensors having different properties. Each image sensor included in the image sensor (230) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0071] The image stabilizer (240) can move at least one lens or image sensor (230) included in the lens assembly (210) in a specific direction or control the operating characteristics of the image sensor (230) (e.g., adjusting the read-out timing, etc.) in response to the movement of the camera module (180) or the electronic device (101) including the same. This allows compensating for at least some of the negative effects of the movement on the captured image. In one embodiment, the image stabilizer (240) can detect such movement of the camera module (180) or the electronic device (101) by using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module (180). In one embodiment, the image stabilizer (240) can be implemented as, for example, an optical image stabilizer. The memory (250) can temporarily store at least a portion of the image acquired through the image sensor (230) for the next image processing task. For example, when image acquisition is delayed due to the shutter, or when multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in the memory (250), and a corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Thereafter, when a specified condition is satisfied (e.g., a user input or a system command), at least a portion of the original image stored in the memory (250) can be acquired and processed, for example, by the image signal processor (260). According to one embodiment, the memory (250) can be configured as at least a portion of the memory (130) or as a separate memory that operates independently therefrom.

[0072] The image signal processor (260) can perform one or more image processing operations on an image acquired through an image sensor (230) or an image stored in a memory (250). The one or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature point extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening).

The second rib (462) may be configured to abut against the first rib (461) when at least one lens (411) moves in a direction substantially orthogonal to the direction along the optical axis (A) (e.g., the Z-axis direction) (e.g., the XY plane direction). The second rib (462) may extend in the circumferential direction of the second hole (422C). The second rib (462) may protrude from one side (e.g., the +Z-direction side) of the top portion (422A). In an embodiment not shown, alternatively or additionally, the second rib (462) may protrude from another side (e.g., the -Z-direction) of the top portion (422A). In one embodiment, the second rib (462) may extend substantially along the entire perimeter of the second hole (422C). The protruding height of the second rib (462) may be substantially equal to or greater than the protruding height of the first rib (461).

[0114] The gap between the first rib (461) and the second rib (462) as viewed in the direction along the optical axis (A) (e.g., the Z-axis direction) may be substantially equal to or smaller than the gap between the lens housing (412) and the second carrier (451) as viewed in the direction along the optical axis (A).

[0115] The camera module (400) may include a stopper (470) configured to restrain the second carrier (451) within a predetermined range in a direction along the optical axis (A) (e.g., the Z-axis direction) so as to prevent the second carrier (451) from being separated from the first carrier (441). The stopper (470) may be referred to as a “Z-stopper.” The stopper (470) may restrict the movement of at least one lens (411) within a predetermined range along the optical axis (A) when an external impact is applied to the camera module (400), thereby preventing the gap between the first carrier (441) and the second carrier (451) from exceeding the predetermined range and preventing the separation of a plurality of first balls (B1) arranged between the first carrier (441) and the second carrier (451). The stopper (470) may include a stopper frame (471) and a stopper hole (472) defined in the stopper frame (471). The lens housing (412) may pass through the stopper hole (472).

[0116] The camera module (400) may include a second flexible printed circuit board (480). The second flexible printed circuit board (480) may be electrically connected to at least one first coil (443A), at least one second coil (443B), and at least one third coil (453). The second flexible printed circuit board (480) may at least partially surround the first carrier (441), the second carrier (451), and the housing frame (421). The second flexible printed circuit board (480) may be electrically connected to the first sensor (444A), the second sensor (444B), and the third sensor (454).

[0117] Fig. 10 is a schematic diagram illustrating an electronic device according to an embodiment. Fig. 11 is a schematic diagram illustrating a range of movement of a lens of a camera module in the electronic device of Fig. 10 according to an embodiment.

[0118] Referring to FIGS. 10 and 11 , the electronic device (301) may include a display module (361) and a camera module (400) (e.g., the first camera module (380A) of FIG. 3 ). The display module (361) may include a camera area (361A-2). The display module (361) may include a display hole (H) that allows the camera module (400) to perform an image stabilization operation in a direction (e.g., an XY plane direction) substantially orthogonal to a direction along the optical axis (A) (e.g., a Z-axis direction). In one embodiment, the display hole (H) may correspond to an area where at least one layer constituting the display module (361) is at least partially removed within the camera area (361A-2). In an embodiment not shown, at least one layer of the display module (361) may not be removed at a position corresponding to the display hole (H).

[0119] The movement of at least one lens (411) (see FIGS. 5 to 9) of the camera module (400) may be configured to be limited within a first limited range (A1) (e.g., a limited range by a hardware stopper (460) of FIGS. 5 to 9). The at least one lens (411) may not exceed the first limited range (A1). The shape of the first limited range (A1) may be complementary to the shape of the display hole (H). For example, forming the display hole (H) so that the display hole (H) has a size corresponding to the angle of view of the at least one lens (411), and forming the display hole (H) to have a substantially circular shape and configuring the first limited range (A1) to have a substantially circular shape complementary to the shape of the display hole (H) may reduce the size of the display hole (H). This may increase the screen display area of ​​the display module (361) (e.g., the screen display area (361A) of FIG. 3).

[0120] The movement of at least one lens (411) (see FIGS. 5 to 9) of the camera module (400) may be configured to be limited within a second limited range (A2). For example, the movement of at least one lens (411) may be limited within the second limited range (A2) by at least one command executable by a processor (e.g., the processor (120) of FIG. 1) stored in a memory (e.g., the memory (130) of FIG. 1) of the electronic device (301). The at least one lens (411) may not go beyond the second limited range (A2). The shape of the second limited range (A2) may be complementary to the shape of the display hole (H). For example, forming the display hole (H) substantially circularly and configuring the second limited range (A2) to have a substantially circular shape complementary to the shape of the display hole (H) may reduce the size of the display hole (H).

[0121] The second limit range (A2) may be substantially equal to or smaller than the first limit range (A1). In some embodiments, the second limit range (A2) may be smaller than the first limit range (A1). This may increase the image quality and reliability acquired through the camera module (400). The difference between the first limit range (A1) and the second limit range (A2) may depend on the type of image captured by the camera module (400). The difference may be determined by considering mechanical deformation and / or driving error (e.g., overshooting in control) of one or more components of the display module (361), the camera module (400), and / or other electronic devices (301) in a specific environment (e.g., a temperature change environment).

[0122] In one embodiment, forming the head portion (412A) (see FIGS. 5 to 9) of the camera module (400) to protrude can reduce the vignetting phenomenon in which the brightness or saturation of an image decreases from the center to the periphery in the captured image.

[0123] Figure 12 is a block diagram of an electronic device according to one embodiment.

[0124] Referring to FIG. 12, an electronic device (401) (e.g., the electronic device (101) of FIG. 1, the electronic device (101) of FIG. 2, the electronic device (301) of FIGS. 3 and 4, and / or the electronic device (301) of FIGS. 10 and 11) may include a processor (120), a sensor module (178), and a camera module (400). The camera module (400) may include a processor (4311) (e.g., a processor configured on a printed circuit board (431) of FIGS. 5 to 9), and a sensor module (444) (e.g., a first sensor (444A), a second sensor (444B), and / or a third sensor (444C) of FIGS. 5 to 10).

[0125] The processor (4311) of the camera module (400) may receive at least one command from the processor (120) of the electronic device (401) so that the camera module (400) may process an operation signal related to image stabilization. For example, the processor (120) may calculate a target position of the first carrier (e.g., the first carrier (441) of FIGS. 5 to 10) based on a value measured from the sensor module (176) (e.g., a gyro sensor), and the processor (4311) may perform position control (e.g., feedback control) of the first carrier based on the target position received from the processor (120). The processor (120) and / or the processor (431) may limit the movement of the first carrier based on a range of the target position of the first carrier (e.g., the second limited range (A2) illustrated in FIGS. 11 and 12). The values ​​measured from the sensor module (176) and / or the values ​​measured from the sensor module (444) of the camera module (400) may be directly transmitted to the processor (431) of the camera module (400), but are not limited thereto, and after being transmitted to the processor (120) of the electronic device (401), at least one command may be transmitted from the processor (120) to the processor (431) of the camera module (400).

[0126] In one embodiment, at least one command may include a command that causes a Cartesian coordinate system to be transformed into a polar coordinate system with respect to a position of at least one lens (e.g., lens (411) of FIGS. 5 to 9). The sensor module (444) of the camera module (400) may detect movement of the at least one lens in a first direction (e.g., X-axis direction) and a second direction (e.g., Y-axis direction) substantially orthogonal to an optical axis (e.g., optical axis (A) of FIGS. 5 to 9), such that the position of the lens in the Cartesian coordinate system may be transformed into a polar coordinate system. This may not require processing that substantially reduces the OIS correction area.

In an embodiment not shown, alternatively or additionally, the plurality of second ribs (461-1) may protrude from another side (e.g., in the -Z direction) of the top portion (422A). The plurality of second ribs (462-1) may be implemented by a simple process (e.g., a bending process) without a specific process (e.g., a deep drawing process).

[0133] The hardware stopper (460-1) may include at least one clearance slot (463). The clearance slot (463) may provide a clearance space for contact between the first rib (461) and at least one second rib (462-1) among the plurality of second ribs (462-1).
