The speaker can be used for general purposes such as multimedia playback or record playback. The receiver can be used to receive incoming calls. According to embodiments, the receiver can be implemented separately from the speaker or as part of the speaker.

[0033] The power management module 188 manages the power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0034] Battery 189 can power at least one component of electronic device 101. According to an embodiment, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.

[0035] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor) 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 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 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 identify or verify the electronic device 101 within 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.

[0036] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies such as New Radio (NR) access technology. NR access technology can support high-speed transmission of large amounts of data (enhanced Mobile Broadband (eMBB)), minimized terminal power and access for multiple terminals (massive machine-type communication (mMTC)), or high reliability and low latency (ultra-reliable low-latency communication (URLLC)). Wireless communication module 192 can support, for example, high-frequency bands (e.g., millimeter-wave bands) to achieve high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive MIMO. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic devices (e.g., electronic device 104), or network systems (e.g., second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0037] Antenna module 197 can transmit or receive signals or power to or from an external source (e.g., an external electronic device). According to embodiments, antenna module 197 may include an antenna comprising a radiator made of a conductor or conductive pattern formed on a substrate (e.g., a PCB). According to embodiments, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190. Signals or power can be transmitted or received between communication module 190 and an external electronic device via the selected at least one antenna. According to some embodiments, additional components besides the radiator (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of antenna module 197.

[0038] According to an embodiment, antenna module 197 can form a millimeter-wave antenna module.

[0039] At least some of the components can be interconnected and exchange signals (e.g., commands or data) via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0040] 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 the second network 199. Each of external electronic device 102 or external electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some of the operations performed on electronic device 101 can be performed on one or more external electronic devices, such as external electronic device 102, external electronic device 104, or server 108. For example, when electronic device 101 needs to automatically perform a function or service, or should perform a function or service in response to a request from a user or another device, electronic device 101 may request one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service independently, or electronic device 101 may request one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service independently. The one or more external electronic devices that have received the request may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and may transmit the result of the performance to electronic device 101. Electronic device 101 may provide the result as is or after further processing as at least a partial response to the request. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used.

[0041] Figure 2a This is a view showing the structure of an electronic device in an unfolded state according to an embodiment, and Figure 2b This is a view showing the structure of an electronic device in a folded state according to an embodiment.

[0042] Reference Figure 2a and Figure 2b The electronic device 101 according to the embodiment is a foldable electronic device and may include a hinge structure covering the foldable portion of the housing 200 (e.g., Figure 2bThe hinge structure 230 (e.g., hinge cover) and the flexible or foldable first display 161 disposed in the space formed by the housing 200 (e.g., Figure 1 The electronic device 101 may include a second display 163 disposed on a portion of the surface of the housing 200 opposite to the surface on which the first display 161 is disposed. According to an embodiment, the surface on which the first display 161 is disposed is defined as a first surface (e.g., a front surface) of the electronic device 101. The surface opposite to the first surface is defined as a second surface (e.g., a rear surface) of the electronic device 101. Furthermore, the surface surrounding the space between the first and second surfaces is defined as a third surface (e.g., a side surface) of the electronic device 101. The second display 163 may be smaller in size than the first display 161.

[0043] According to an embodiment, the housing 200 may include a first housing structure 210, a second housing structure 220 including a sensor region 224, a first rear cover 280, a second rear cover 290, and a hinge structure 230. The housing 200 of the electronic device 101 is not limited to... Figure 2a and Figure 2b The shapes and combinations shown can be implemented through combinations and / or couplings of other shapes or components. For example, in another embodiment, the first housing structure 210 and the first rear cover 280 may be integrally formed, and the second housing structure 220 and the second rear cover 290 may be integrally formed.

[0044] According to an embodiment, the first housing structure 210 and the second housing structure 220 surround a folding axis (e.g., Figure 2a The folding axis A is arranged on both sides and can have an overall symmetrical shape with respect to the folding axis A. As described below, the angle or distance formed between the first housing structure 210 and the second housing structure 220 can vary depending on whether the electronic device 101 is in an unfolded state, a folded state, or an intermediate state where the device is partially unfolded. According to an embodiment, unlike the first housing structure 210, the second housing structure 220 additionally includes a sensor area 224 where various sensors are provided, but it can have a symmetrical shape with each other in other areas.

[0045] According to an embodiment, the first housing structure 210 and the second housing structure 220 are connected to the hinge structure 230 and can be folded or unfolded when they rotate about the hinge structure 230. Therefore, the electronic device 101 can be transformed into a folded state or an unfolded state. The electronic device 101 can be accessed from, for example... Figure 2a The unfolded state transitions to the folded state (e.g., Figure 2bIn the inward folded state, the first surface of the first housing structure 210 and the third surface of the second housing structure 220 become closer to each other and face each other. The electronic device 101 can then access the device from the inside. Figure 2a The unfolded state transitions to a folded state (e.g., an outward folded state), in which the second surface of the first housing structure 210 and the fourth surface of the second housing structure 220 face each other and simultaneously become closer to each other.

[0046] According to the embodiments, such as Figure 2a As shown, the first housing structure 210 and the second housing structure 220 can together form a recess for accommodating the first display 161. According to an embodiment, due to the sensor region 224, the recess can have two or more different widths in a direction perpendicular to the folding axis A. According to an embodiment, the recess can have a first width w1 between a first portion 210a of the first housing structure 210 parallel to the folding axis A and a first portion 220a of the second housing structure 220 formed at the edge of the sensor region 224. The recess can have a second width w2 formed by a second portion 210b of the first housing structure 210 and a second portion 220b of the second housing structure 220, which does not correspond to the sensor region 224 and is parallel to the folding axis A. In this case, the second width w2 can be longer than the first width w1. As another example, a first portion 210a of a first housing structure 210 and a first portion 220a of a second housing structure 220, having asymmetrical shapes, may form a first width w1 of the recess, and a second portion 210b of a first housing structure 210 and a second portion 220b of a second housing structure 220, having symmetrical shapes, may form a second width w2 of the recess. According to an embodiment, the first portion 220a and the second portion 220b of the second housing structure 220 may have different distances from the folding axis A. The width of the recess is not limited to the example shown. In another embodiment, depending on the shape of the sensor region 224 or the asymmetrically shaped portions of the first housing structure 210 and the second housing structure 220, the recess may have multiple widths.

[0047] According to an embodiment, at least a portion of the first housing structure 210 and the second housing structure 220 may be formed from a rigid metallic or non-metallic material having dimensions selected to support the first display 161. The at least portion formed of metal may provide a ground plane for the electronic device 101 and may be electrically connected to a ground wire formed on a printed circuit board.

[0048] According to an embodiment, the sensor region 224 may be formed having a predetermined area adjacent to a corner of the second housing structure 220. However, the arrangement, shape, and size of the sensor region 224 are not limited to the example shown. For example, in another embodiment, the sensor region 224 may be located at another corner of the second housing structure 220 or in any area between an upper and lower corner. In an embodiment, components embedded in the electronic device 101 for performing various functions may be visually exposed on the front surface of the electronic device 101 through the sensor region 224 or through one or more openings provided in the sensor region 224. In various embodiments, the components may include various types of sensors. The sensors may include at least one of, for example, a front-facing camera 24, a receiver, or a proximity sensor.

[0049] According to an embodiment, a first rear cover 280 is disposed on one side of the folding axis on the rear surface of the electronic device 101 and may have a substantially rectangular periphery, the periphery of which may be surrounded by a first housing structure 210. Similarly, a second rear cover 290 is disposed on the other side of the folding axis on the rear surface of the electronic device 101 and its periphery may be surrounded by a second housing structure 220.

[0050] According to an embodiment, the first rear cover 280 and the second rear cover 290 may have a shape that is substantially symmetrical about the folding axis (A-axis). However, the first rear cover 280 and the second rear cover 290 are not necessarily symmetrical to each other, and in another embodiment, the electronic device 101 may include a first rear cover 280 and a second rear cover 290 of various shapes. In another embodiment, the first rear cover 280 may be integrally formed with the first housing structure 210, and the second rear cover 290 may be integrally formed with the second housing structure 220.

[0051] According to an embodiment, the first rear cover 280, the second rear cover 290, the first housing structure 210, and the second housing structure 220 may form a space for housing various components of the electronic device 101 (e.g., printed circuit boards or batteries). According to an embodiment, one or more components may be arranged on or visually exposed on the rear surface of the electronic device 101. For example, at least a portion of a sub-display may be visually exposed through a first rear region 282 of the first rear cover 280. In another embodiment, one or more components or sensors may be visually exposed through a second rear region 292 of the second rear cover 290. In an embodiment, the sensor may include a proximity sensor and / or a rear camera.

[0052] According to embodiments, a front-facing camera visually exposed on the front surface of the electronic device 101 through one or more openings in sensor region 224, or a rear-facing camera exposed through the second rear region 292 of the second rear cover 290, may include one or more lenses, an image sensor, and / or an image signal processor. A flash may include, for example, a light-emitting diode or a xenon lamp. In some embodiments, two or more lenses (infrared camera, wide-angle lens, and telephoto lens) and an image sensor may be disposed on one surface of the electronic device 101.

[0053] Reference Figure 2b The hinge structure 230 may be disposed between the first housing structure 210 and the second housing structure 220, and is configured to cover internal components. According to an embodiment, depending on the folded state of the electronic device 101 (unfolded state, intermediate state, or folded state), the hinge structure 230 may be partially covered by the first housing structure 210 and the second housing structure 220, or exposed to the outside. According to an embodiment, such as... Figure 2a As shown, when the electronic device 101 is in the unfolded state, the hinge structure 230 can be covered by the first housing structure 210 and the second housing structure 220 and is not exposed. As another example, such as... Figure 2b As shown, when the electronic device 101 is in a folded state (e.g., a fully folded state), the hinge structure 230 may be exposed to the outside between the first housing structure 210 and the second housing structure 220. As another example, when the first housing structure 210 and the second housing structure 220 are in an intermediate state folded at an angle, the hinge structure 230 may be partially exposed to the outside between the first housing structure 210 and the second housing structure 220. However, in this case, the exposed area may be smaller than the exposed area in the fully folded state. In embodiments, the hinge structure 230 may include a curved surface.

[0054] According to an embodiment, a first display 161 may be disposed in the space formed on a first surface of a first housing structure 210 and a third surface of a second housing structure 220. According to an embodiment, a second display 163 may be disposed in the space formed on a second surface of a first housing structure 210 or a fourth surface of a second housing structure 220. For example, the first display 161 may be disposed on a recess formed by a housing 200 and may constitute a large portion of the front surface of an electronic device 101. According to an embodiment, the first display 161 may refer to a display whose at least a portion can be transformed into a flat surface or a curved surface. According to an embodiment, the first display 161 may include a folded region 203, and a portion disposed on the first housing structure 210 on one side relative to the folded region 203 (e.g., Figure 2a The first display area 201 on the left side of the folded area 203 shown, and the other display area on the second housing structure 220 (e.g., Figure 2a The second display area 202 is located on the right side of the folded area 203 shown in the diagram.

[0055] However, Figure 2a The area division of the first display 161 shown is exemplary, and the first display 161 may be divided into multiple areas (e.g., four or more, or two) according to its structure or function. For example, in Figure 2a In the illustrated embodiment, the area of ​​the first display 161 may be divided by a folded region 203 extending parallel to the y-axis or a folding axis (A-axis). However, in another embodiment, the area of ​​the first display 161 may be divided based on another folded region (e.g., a folded region parallel to the x-axis) or another folding axis (e.g., a folding axis parallel to the x-axis). According to embodiments, the first display 161 and the second display 163 may be coupled to touch sensing circuitry, a pressure sensor capable of measuring the intensity (pressure) of the touch, and / or a digital converter for detecting a magnetic field type stylus, or may be arranged adjacent to touch sensing circuitry, a pressure sensor capable of measuring the intensity (pressure) of the touch, and / or a digital converter for detecting a magnetic field type stylus.

[0056] According to an embodiment, the first display area 201 and the second display area 202 may have an overall symmetrical shape with respect to the folded area 203. However, unlike the first display area 201, the second display area 202 may include grooves cut according to the presence of the sensor area 224, but may have a shape symmetrical to the first display area 201 in other areas. In other words, the first display area 201 and the second display area 202 may include portions with shapes symmetrical to each other and portions with shapes asymmetrical to each other.

[0057] The operation of the first housing structure 210 and the second housing structure 220, as well as each area of ​​the first display 161, will be described below according to the state of the electronic device 101 (e.g., folded state, unfolded state, or intermediate state).

[0058] According to an embodiment, when the electronic device 101 is in an unfolded state (e.g., Figure 2a In its unfolded state, the first housing structure 210 and the second housing structure 220 can form a 180-degree angle and are arranged to face the same direction. The surfaces of the first display area 201 and the second display area 202 of the first display 161 form a 180-degree angle with each other and can face the same direction (e.g., the front direction of the electronic device). The folded area 203 can form a coplanar plane with the first display area 201 and the second display area 202.

[0059] According to an embodiment, when the electronic device 101 is in a folded state (e.g., Figure 2bWhen in the folded state, the first housing structure 210 and the second housing structure 220 can be arranged to face each other. The surfaces of the first display area 201 and the second display area 202 of the first display 161 form a narrow angle with each other (e.g., between 0 and 10 degrees) and can face each other. At least a portion of the folded area 203 can be a curved surface with a predetermined curvature.

[0060] According to an embodiment, when the electronic device 101 is in a folded state, the first housing structure 210 and the second housing structure 220 can be arranged at an angle to each other. The surfaces of the first display area 201 and the second display area 202 of the first display 161 can form an angle larger than that in the folded state and smaller than that in the unfolded state. At least a portion of the folded area 203 can be a curved surface with a predetermined curvature, and the curvature at this time can be smaller than the curvature in the folded state.

[0061] According to embodiments, the electronic device 101 may include an inward-folding type or an outward-folding type. An inward-folding type may refer to a state where the flexible first display 161 is not exposed to the outside when fully folded. As another example, it may refer to a state where the first display 161 is folded towards the forward direction. An outward-folding type may refer to a state where the first display 161 is visually exposed to the outside when fully folded. As another example, it may refer to a state where the first display 161 is folded towards the rearward direction. For example, the electronic device 101 may be in an unfolded state (e.g., Figure 2a Multiple windows are displayed in the expanded state.

[0062] exist Figure 2a and Figure 2b The text describes an example of expanding the display area (i.e., increasing the display area) using a flexible display, but electronic devices may have a display area that can be expanded using a rollable display, or a display area of ​​a size that can be displayed in multiple windows, rather than being flexible or rollable.

[0065] The electronic device according to the embodiment can be used in electronic devices (e.g., Figure 2aIn the unfolded state of the electronic device 101, the front-facing camera 24 is positioned with the second housing of the electronic device (e.g., Figure 2a The third surface of the second housing 220 (or the first housing (e.g., Figure 2a The first surface of the first housing 210 corresponds to a portion of the front surface, and the front camera 24 may include an under-display camera (UDC).

[0066] The electronic device according to the embodiment can be used in electronic devices (e.g., Figure 2a In the unfolded state of the electronic device 101, in relation to the first housing of the electronic device (e.g., Figure 2a The second surface of the first housing 210 and the second housing (e.g., Figure 2a Multiple rear cameras 393 and front cover cameras 383 are respectively provided in a portion of the rear surface corresponding to the fourth surface of the second housing 220.

[0067] The electronic device according to the embodiment may be, for example, Figure 3 In the vertical orientation shown, stereoscopic images are captured using at least two of the multiple rear cameras 393 and the front cover camera 383.

[0068] According to embodiments, a "stereoscopic image" is an image obtained by two or more cameras and can be used to mean a pair of 2D images that allow the perception of three-dimensionality (depth) by using the parallax between the two eyes. For example, a stereoscopic image may include a left-eye image corresponding to the left eye and a right-eye image corresponding to the right eye. According to embodiments, stereoscopic images can be played back by electronic devices developed in a wearable form by the user (e.g., wearable electronics such as augmented reality (AR) glasses, video see-through (VST) devices, or head-mounted display (HMD) devices) and can be displayed to the user as a 3D image. Stereoscopic images may also be referred to by the term "spatial video," but are not limited to that specific term.

For example, in the electronic device in the vertical direction ( Figure 2a In the state of being placed in the direction shown, stereoscopic images can be captured by using one of the multiple rear cameras and the front cover camera 383.

[0070] According to the embodiments, such as Figure 2a As shown, when included in the second rear cover of an electronic device (e.g., Figure 2aWhen the multiple rear cameras in the second rear region 292 of (290) include multiple first rear cameras 393 arranged in a row, the multiple first rear cameras 393 may be an ultra-wide-angle camera 393-1, a wide-angle camera 393-2 and a telephoto camera 393-3.

[0071] According to the embodiments, such as Figure 3 As shown, when included in the second rear cover of an electronic device (e.g., Figure 2a When the plurality of rear cameras in the second rear region 292 of (290) include a plurality of first rear cameras 393 arranged in two rows and at least one second rear camera 394, the plurality of first rear cameras 393 in the first row are an ultra-wide-angle camera 393-1, a wide-angle camera 393-2 and a telephoto camera 393-3, and at least one second rear camera 394 in the second row can be a telephoto camera.

[0072] According to an embodiment, when the electronic device is foldable, such as Figure 2a and Figure 3 As shown, when the electronic device is fully deployed, the front cover camera 383 and the plurality of rear cameras 393 and / or 394 can face the same direction. Therefore, a stereoscopic image can be obtained by using at least one of the front cover camera 383 and the plurality of rear cameras 393 and / or 394.

[0073] According to an embodiment, in the embodiments described below, for ease of description, among the multiple cameras used for stereoscopic image capture, multiple rear cameras 393 may be configured as cameras corresponding to the right eye, and a front-facing camera 383 may be configured as a camera corresponding to the left eye. According to an embodiment, multiple rear cameras 393 and / or 394 may be configured as cameras corresponding to the left eye, and a front-facing camera 383 may be configured as a camera corresponding to the left eye.

According to an embodiment, the electronic device may acquire left-eye and right-eye images of the stereoscopic image based on the first and second images.

[0075] An electronic device may display, via a display (e.g., a flexible display), an image set as a preview image (e.g., the first image or the second image) from a first image and a second image as a preview image.

[0088] Figure 4 This is a flowchart illustrating the operation of selecting two cameras for generating stereoscopic images based on the tilt angle of the electronic device according to an embodiment.

[0089] Reference Figure 4 According to an embodiment, in operation 410, the electronic device (e.g., Figure 1 Electronic device 101 Figure 1 Processor 120 Figure 2a The electronic device 101 may be received based on user input for stereo image capture, and the tilt of the electronic device may be sensed by at least one sensor.

[0090] According to an embodiment, when user input (e.g., touch input or voice input) for capturing stereoscopic images is received via the execution screen of a camera application, the electronic device can sense the tilt of the electronic device through at least one sensor (e.g., ... Figure 1 The sensor module 176 is used to sense the tilt of the electronic device. For example, at least one sensor may include at least one of a gyroscope sensor or an accelerometer sensor.

[0091] According to an embodiment, in operation 420, the electronic device may select two cameras from a plurality of rear cameras based on the sensed tilt being included in a first range, and select two cameras arranged in a second direction different from the first direction from a plurality of rear cameras and front cover cameras based on the sensed tilt being included in a second range different from the first range.

[0092] For example, the first range may include a range of more than 90 degrees and less than 180 degrees, and the second range may include a range of 0 degrees or more and 90 degrees or less.

[0093] According to an embodiment, the front-cover camera may be disposed in the first housing (e.g., Figure 2a First shell structure 210 or Figure 2b On the second surface of the first housing structure 210, and multiple rear cameras may be mounted on the second housing (e.g., Figure 2a The second shell structure 220 or Figure 2b On the fourth surface of the second shell structure 220.

[0094] According to embodiments, the electronic device may be based solely on the electronic device's... Figure 2a The tilt of the plane formed by the x-axis and y-axis in the coordinate system shown is used to select two cameras. For example, the electronic device can select two cameras corresponding to the left and right eyes, respectively, for stereoscopic image capture. According to an embodiment, the electronic device can select two cameras arranged left and right for stereoscopic image capture based on the tilt of the electronic device.

[0095] According to an embodiment, when the sensed tilt of the electronic device is included within a first range, the electronic device can be identified as corresponding to a "lateral mode". According to an embodiment, the lateral mode can be a state in which the hinge structure includes elements parallel to... Figure 2a The coordinate system shown has the x-axis in the direction and is arranged in a lateral (or horizontal) direction within a set angle from the x-axis. According to an embodiment, when the sensed tilt of the electronic device is included in a first range, the first direction in which a plurality of rear cameras including those in a fourth surface of the electronic device are arranged includes a direction parallel to the x-axis and may be a lateral (or horizontal) direction within a set angle from the x-axis.

[0096] According to an embodiment, when the electronic device is in landscape mode, the electronic device can select two cameras (e.g., an ultra-wide-angle camera and a wide-angle camera) from a plurality of rear cameras arranged in a first direction parallel to the hinge structure.

[0097] According to an embodiment, when the sensed tilt of the electronic device is included in a second range different from the first range, the electronic device can be identified as corresponding to a "vertical mode". According to an embodiment, the vertical mode can be a state in which the hinge structure includes elements perpendicular to... Figure 2a The coordinate system shown is oriented along the x-axis and is positioned along a longitudinal (or vertical) direction that deviates from the x-axis direction by an angle beyond the set point.

[0098] According to an embodiment, when the sensed tilt of the electronic device is included in the second range, the first direction in which a plurality of rear cameras are arranged in the fourth surface of the electronic device includes a direction perpendicular to the x-axis, and may be a longitudinal direction (or vertical direction) deviating from the x-axis direction within the set angle.

[0099] According to an embodiment, when the electronic device is in portrait mode, it can select two cameras arranged in a second direction from a plurality of rear cameras and a front-facing camera. This second direction is different from a first direction parallel to the hinge structure. According to an embodiment, the second direction may include a direction within a set angle, including a direction perpendicular to the first direction.

[0100] According to an embodiment, when the electronic device is in portrait mode, the electronic device can select two cameras from a plurality of rear cameras and a front-facing camera by further considering the folded state of the electronic device. For example, the electronic device can further consider the folded state of the electronic device by using at least one sensor (e.g., ...) Figure 1 The sensor module 176 senses the folding angle to select two cameras from a plurality of rear cameras and a front cover camera. For example, at least one sensor for sensing the folding state of the electronic device may include an accelerometer and / or a Hall sensor.

[0101] According to an embodiment, the electronic device may select one of a plurality of rear cameras and a front cover camera based on the sensed tilt angle of the electronic device being included in a second range and the folding angle sensed by a second sensor being included in a first range. For example, when the electronic device is in portrait mode and the folding angle is within a first range that the plurality of rear cameras and the front cover camera can capture the same subject, the electronic device may select one of the plurality of rear cameras and the front cover camera.

[0102] According to an embodiment, when the folding angle is within a first range, the electronic device can be identified as corresponding to the unfolded state of the first housing and the second housing being unfolded.

[0103] According to an embodiment, when the plurality of rear cameras include a plurality of first rear cameras arranged in a row, and when the electronic device is in portrait mode and unfolded state, as described above, the electronic device may select one of the plurality of first rear cameras (e.g., an ultra-wide-angle camera) and a front-mount camera. According to an embodiment, the selected rear camera and the front-mount camera may be arranged in a second direction.

[0104] In this way, even in portrait mode, the electronic device can capture stereoscopic images by using a rear camera and a front-facing camera, and can obtain stereoscopic images with improved depth perception depending on the distance between the rear camera and the front-facing camera.

[0105] According to an embodiment, when the plurality of rear cameras include a plurality of first rear cameras arranged in two rows and at least one second rear camera, and when the electronic device is in portrait mode and unfolded state, the electronic device may select one of the plurality of rear cameras and the front cover camera, or select one of the plurality of first rear cameras in the first row (e.g., a wide-angle camera) and one of at least one second rear camera in the second row (e.g., a telephoto camera).

[0106] According to an embodiment, a selected rear camera and a front-facing camera, or a selected rear camera in the first row and a selected rear camera in the second row, can be arranged in a second direction.

[0107] For example, regarding the use of stereoscopic images or the performance of stereoscopic images as desired by the user, when the sense of depth of the stereoscopic image is more important than the quality of the stereoscopic image (e.g., image quality), the electronic device may select one of a plurality of rear cameras and a front-mounted camera.

[0108] According to an embodiment, when the quality of the stereoscopic image (e.g., image quality) is more important than the sense of depth of the stereoscopic image, the electronic device may select one of a plurality of first rear cameras in a first row and one of at least one second rear camera in a second row.

[0109] Thus, even in portrait mode, the electronic device can capture stereoscopic images by using one of the plurality of first rear cameras in the first row and one of at least one second rear camera in the second row, and can obtain stereoscopic images with improved quality depending on the performance of the rear cameras.

[0110] According to an embodiment, the electronic device may provide an indication that a stereoscopic image cannot be generated based on the sensed tilt angle of the electronic device being included within a second range and the folding angle being outside a first range. For example, when the electronic device is in portrait mode and the folding angle is outside a first range where multiple rear cameras and a front-facing camera can capture the same subject, the electronic device may provide an indication that a stereoscopic image cannot be generated. According to an embodiment, when the folding angle is outside the first range, the electronic device may be identified as corresponding to a half-folded state where the first and second housings are partially folded or a folded state where the first and second housings are folded.

[0111] According to an embodiment, when the plurality of rear cameras consist only of a plurality of first rear cameras arranged in a row, and when the electronic device is in portrait mode and in a semi-folded or folded state, as described above, the electronic device can provide an indicator that a stereoscopic image cannot be generated.

[0112] According to an embodiment, when the plurality of rear cameras include a plurality of first rear cameras arranged in two rows and at least one second rear camera, and when the electronic device is in portrait mode and in a semi-folded or folded state, the electronic device can select one of the plurality of first rear cameras in the first row (e.g., a wide-angle camera) and one of at least one second rear camera in the second row (e.g., a telephoto camera). According to an embodiment, the selected rear cameras in the first row and the second rear cameras in the second row can be arranged in a second direction.

[0113] Thus, even in the semi-folded or folded state of the portrait mode, stereoscopic images can be captured by using one of the multiple first rear cameras in the first row and one of the at least one second rear camera in the second row, and stereoscopic images with improved quality can be obtained depending on the performance of the rear cameras.

[0114] According to the embodiments, the following will refer to Figure 5 The operation of selecting two cameras for capturing stereoscopic images is described in more detail by taking into account the folded state of the electronic devices.

[0115] According to the embodiments, the following will refer to Figure 6 A more detailed description of the operation of selecting the two cameras to capture stereo images when multiple rear cameras are arranged in two rows.

[0116] According to an embodiment, in operation 430, the electronic device can obtain stereoscopic images through two selected cameras. According to an embodiment, the electronic device can obtain a left-eye image through one of the two selected cameras and a right-eye image through the other.

[0117] According to an embodiment, the electronic device can perform image processing to horizontally align the acquired left-eye and right-eye images. For example, correction can be performed such that corresponding points included in the left-eye and right-eye images, respectively, have the same y-coordinate.

[0118] According to an embodiment, the electronic device can store the corrected stereoscopic image in a memory (e.g., Figure 1 In the memory 130).

[0119] According to an embodiment, the electronic device can be communicated via a communication module (e.g., Figure 1 The communication module 190 sends the corrected stereoscopic image to an external electronic device (e.g., a head-mounted display (HMD) device).

[0120] Figure 5 This is a flowchart illustrating the operation of selecting two cameras for generating stereoscopic images based on the tilt and folding state of the electronic device according to an embodiment of the present disclosure.

[0121] Reference Figure 5According to an embodiment, in operation 501, the electronic device (e.g., Figure 1 Electronic device 101 Figure 1 Processor 120 Figure 2a The electronic device 101 can receive user input for stereoscopic image capture. For example, the electronic device can receive user input (e.g., touch input or voice input) for capturing stereoscopic images via the execution screen of a camera application.

[0122] According to an embodiment, in operation 502, the electronic device can identify whether the tilt angle of the electronic device is within a first range.

[0123] According to an embodiment, the electronic device can be detected by at least one sensor (e.g., for sensing the tilt of the electronic device) Figure 1 The sensor module 176 is used to sense the tilt of the electronic device.
