For example, if the electronic device (101) includes a main processor (121) and an auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a designated function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as part thereof.

[0037] The auxiliary processor (123) may control at least some of the functions or states associated with at least one component of the electronic device (101) (e.g., display module (160), sensor module (176), or communication module (190)) on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. According to one example, the auxiliary processor (123) (e.g., image signal processor or communication processor) may be implemented as part of another functionally related component (e.g., camera module (180) or communication module (190)). According to one example, the auxiliary processor (123) (e.g., neural network processing unit) may include a hardware structure specialized for processing an artificial intelligence model.

According to one example, the receiver may be implemented separately from the speaker or as part thereof.

[0042] The display module (160) can visually provide information to an external (e.g., user) of the electronic device (101). The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling said device. According to one example, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of the force generated by said touch.

[0043] The audio module (170) can convert sound into an electrical signal or, conversely, convert an electrical signal into sound. According to one example, the audio module (170) can acquire sound through an input module (150) or output sound through an audio output module (155) or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphones) connected directly or wirelessly to the electronic device (101).

[0044] The sensor module (176) can detect the operating state of the electronic device (101) (e.g., power or temperature) or the external environmental state (e.g., user state) and generate an electrical signal or data value corresponding to the detected state.

[0045] The interface (177) may support one or more specified protocols that can be used for the electronic device (101) to be connected directly or wirelessly to an external electronic device (e.g., electronic device (102)). According to one example, the interface (177) may include, for example, a high definition multi-media interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0046] The connection terminal (178) may include a connector through which the electronic device (101) can be physically connected to an external electronic device (e.g., electronic device (102)). According to one example, the connection terminal (178) may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0051] The communication module (190) can support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between an electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may include one or more communication processors that operate independently of the processor (120) (e.g., application processor) and support direct (e.g., wired) communication or wireless communication. According to one example, the communication module (190) may include a wireless communication module (192) (e.g., cellular communication module, short-range wireless communication module, or GNSS (global navigation satellite system) communication module) or a wired communication module (194) (e.g., LAN (local area network) communication module, or power line communication module). The corresponding communication module among these communication modules can communicate with an external electronic device (104) through a first network (198) (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (199) (e.g., 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 may 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 authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)) stored in the subscriber identification module (196).

[0052] The wireless communication module (192) can support 5G networks and next-generation communication technologies following 4G networks, for example, new radio access technology. NR access technology can support high-speed transmission of high-capacity data (enhanced mobile broadband (eMBB)), minimization of terminal power and connection of multiple terminals (massive machine type communications (mMTC)), or high reliability and low latency (ultra-reliable and low-latency communications (URLLC)). The wireless communication module (192) can support a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate, for example. The wireless communication module (192) can support various technologies for securing performance in the high-frequency band, such as beamforming, massive MIMO (multiple-input and multiple-output), full-dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or largescale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), external electronic device (e.g., electronic device (104)), or network system (e.g., second network (199)). According to one example, the wireless communication module (192) can support a Peak data rate (e.g., 20 Gbps or more) for eMBB realization, loss coverage (e.g., 164 dB or less) for mMTC realization, or U-plane latency (e.g., downlink (DL) and uplink (UL) each 0.5 ms or less, or round trip 1 ms or less) for URLLC realization.

[0053] An antenna module (197) can transmit a signal or power to or from an external source (e.g., an external electronic device). According to one example, the antenna module (197) may include an antenna comprising a radiator made of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). According to one example, 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 a first network (198) or a second network (199), may be selected from the plurality of antennas, for example, by a communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. According to some examples, in addition to the radiator, other components (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of the antenna module (197).

[0054] According to various examples, the antenna module (197) can form a mmWave antenna module. According to one example, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent to a first surface (e.g., bottom surface) of the printed circuit board and capable of supporting a specified high frequency band (e.g., mmWave band), and a plurality of antennas (e.g., array antennas) disposed on or adjacent to a second surface (e.g., top surface or side surface) of the printed circuit board and capable of transmitting or receiving a signal of the specified high frequency band.

[0055] At least some of the above components can be connected to each other via a communication method between peripheral devices (e.g., bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)) and exchange signals (e.g., commands or data) with each other.

[0056] According to one example, commands or data may be transmitted or received between an electronic device (101) and an external electronic device (104) through a server (108) connected to a second network (199). Each of the external electronic devices (102, or 104) may be the same or different type of device as the electronic device (101). According to one example, all or part of the operations performed on the electronic device (101) may be performed on one or more of the external electronic devices (102, 104, or 108). For example, if the electronic device (101) needs to perform a function or service automatically or in response to a request from a user or another device, the electronic device (101) may request one or more external electronic devices to perform at least part of the function or service instead of performing the function or service itself or additionally. One or more external electronic devices that receive the above request may execute at least part of the requested function or service, or additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may provide the result as is or additionally processed as at least part of the response to the request. For this purpose, for example, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used. The electronic device (101) may provide ultra-low latency services using, for example, distributed computing or mobile edge computing. In another example, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server using machine learning and / or neural networks. According to one example, the external electronic device (104) or the server (108) may be included within 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.

[0069] Hereinafter, for convenience of explanation, a spatial coordinate system (or orthogonal coordinate system) including an X-axis, a Y-axis, or a Z-axis is illustrated in FIGS. 2a through 16. The reference housing for the X-axis direction, Y-axis direction, or Z-axis direction may differ for each description of the drawings. For example, in FIG. 2a, with respect to the first housing part (210), the Z-axis direction is the front of the first housing part (210), and the -Z-axis direction is the rear of the first housing part (210).

[0070] The examples of FIGS. 2a to 4e can be combined with the example of FIG. 1 or the examples of FIG. 5 to 13.

For example, the z-type electronic device (101z) corresponds to the latter, the first hinge structure (240) may be an out-folding structure, and the second hinge structure (250) may be an in-folding structure.

[0075] According to one example, the first hinge structure (240) may be connected to the first housing portion (210) or the second housing portion (220). The second housing portion (220) may be rotatably connected to the first housing portion (210) through the first hinge structure (240). According to one example, the second hinge structure (250) may be connected to the second housing portion (220) or the third housing portion (230). The third housing portion (230) may be rotatably connected to the second housing portion (220) through the second hinge structure (250).

[0076] According to one example, the first housing portion (210) may be connected to the first hinge structure (240). The first housing portion (210) may include a first front facing a first direction (e.g., the +Z direction in FIG. 2a) or a first rear facing a second direction opposite to the first direction (e.g., the -Z direction in FIG. 2b). The second housing portion (220) may be connected to the first hinge structure (240). The second housing portion (220) may include a second front facing a first direction (e.g., the +Z direction in FIG. 2a) or a second rear facing a second direction opposite to the first direction (e.g., the -Z direction in FIG. 2b).

[0077] According to one example, the first housing portion (210) can rotate about the second housing portion (220) around the first hinge structure (240). The first housing portion (210) and the second housing portion (220) can be provided in a folded state (e.g., FIG. 2c to FIG. 2e) or an unfolded state (e.g., FIG. 2a to FIG. 2b). In one example, the e-type electronic device (101e) and the G-type electronic device (101G) may have the first hinge structure (240) as an in-folding structure. In one example, the z-type electronic device (101z) may have the first hinge structure (250) as an out-folding structure.

[0078] According to one example, the e-type electronic device (101e) of FIGS. 2a to 2e and the G-type electronic device (101G) of FIGS. 3a to 3e can be folded in such a way that the first front of the first housing part (210) and the second front of the second housing part (220) come into contact with each other by rotating the second housing part (220) relative to the first housing part (210) by means of the in-folding structure of the first hinge structure (240).

[0079] When the first housing portion (210) and the second housing portion (220) of the e-type electronic device (101e) and the G-type electronic device (101G) are in a folded state, the first front surface of the first housing portion (210) may face the second front surface of the second housing portion (220). When the first housing portion (210) and the second housing portion (220) are in a folded state, parts (e.g., A1, A2, A4) of the flexible display (203) placed on the front surfaces of the first housing portion (210) and the second housing portion (220) may not be exposed to the outside. When the first housing portion (210) and the second housing portion (220) are in a folded state, the first rear surface of the first housing portion (210) and the second rear surface of the second housing portion (220) may face in opposite directions.

[0080] When the first housing portion (210) and the second housing portion (220) of the e-type electronic device (101e) and the G-type electronic device (101G) are in an unfolded state, the first front of the first housing portion (210) and the second front of the second housing portion (220) may face in the same direction. When the first housing portion (210) and the second housing portion (220) are in an unfolded state, parts (e.g., A1, A2, A4) of the flexible display (203) placed on the front of the first housing portion (210) and the second housing portion (220) may be exposed to the outside. When the first housing portion (210) and the second housing portion (220) are in an unfolded state, the first rear of the first housing portion (210) and the second rear of the second housing portion (220) may face in the same direction.

[0081] According to one example, by means of the out-folding structure of the first hinge structure (240) of the z-type electronic device (101z) of FIG. 4a to 4e, the second housing part (220) can be rotated relative to the first housing part (210) so that the first front of the first housing part (210) and the second front of the second housing part (220) can be folded toward each other. When the first housing part (210) and the second housing part (220) of the z-type electronic device (101z) are in a folded state, the first rear of the first housing part (210) of the z-type electronic device (101z) can face the second rear of the second housing part (220). When the first housing portion (210) and the second housing portion (220) of the z-type electronic device (101z) are in a folded state, the first front of the first housing portion (210) may face in a direction opposite to the second front of the second housing portion (220). When the first housing portion (210) and the second housing portion (220) of the z-type electronic device (101z) are in a folded state, a part (A1) of the flexible display (203) placed on the front of the first housing portion (210) and a part (A2) of the flexible display (203) placed on the front of the second housing portion (220) may face in opposite directions. Depending on the user's position, if a part of the flexible display (203) (e.g., A1 or A2) is exposed, the other part (e.g., A2 or A1) may be out of the user's field of view.

[0082] When the first housing portion (210) and the second housing portion (220) of the z-type electronic device (101z) are in an unfolded state, the first front surface of the first housing portion (210) may face the same direction as the second front surface of the second housing portion (220). When the first housing portion (210) and the second housing portion (220) of the z-type electronic device (101z) are in an unfolded state, the first rear surface of the first housing portion (210) may face the same direction as the second rear surface of the second housing portion (220).

[0083] According to one example, the second housing portion (220) may be connected to the second hinge structure (250). In one example, the second hinge structure (250) of the e-type electronic device (101e), the G-type electronic device (101G), and the z-type electronic device (101z) may all have an in-folding structure. The third housing portion (230) may be connected to the second hinge structure (250). The third housing portion (230) may include a third front face facing a first direction (e.g., the +Z direction in FIG. 2a), or a third rear face facing a second direction opposite to the first direction (e.g., the -Z direction in FIG. 2b).

[0084] According to one example, the second housing portion (220) can rotate relative to the third housing portion (230) around the second hinge structure (250). The second housing portion (220) and the third housing portion (230) can be provided in a folded state (e.g., FIG. 3a to FIG. 3g) or an unfolded state (e.g., FIG. 2a to FIG. 2b). When the second housing portion (220) and the third housing portion (230) of the e-type electronic device (101e), G-type electronic device (101G), and z-type electronic device (101z) are in a folded state, the second front of the second housing portion (220) can face the third front of the third housing portion (230). When the second housing portion (220) and the third housing portion (230) of the e-type electronic device (101e), G-type electronic device (101G), and z-type electronic device (101z) are in a folded state, the second rear side of the second housing portion (220) may face in the opposite direction to the third rear side of the third housing portion (230). When the second housing portion (220) and the third housing portion (230) of the e-type electronic device (101e), G-type electronic device (101G), and z-type electronic device (101z) are in an unfolded state, the second front side of the second housing portion (220) may face in the same direction as the third front side of the third housing portion (230). When the second housing portion (220) and the third housing portion (230) of the e-type electronic device (101e), G-type electronic device (101G), and z-type electronic device (101z) are in an unfolded state, the second rear surface of the second housing portion (220) may face in the same direction as the third rear surface of the third housing portion (230).

[0085] According to one example, when both the first hinge structure (240) and the second hinge structure (250) are in-folding structures, the width of the first hinge structure (240) and the width of the third hinge structure (250) may differ. In one example, for the e-type electronic device (101a) and the G-type electronic device (101G), the first housing part (210) is folded inward by the in-folding structure with respect to the second housing part (220), and the third housing part (230) can also be folded inward by the in-folding structure. For example, for the e-type electronic device (101e), the first housing part (210) may be folded first, and the third housing part (230) may be folded later. The e-type electronic device (101e) may be in a folded state in which the second housing portion (220), the first housing portion (210), and the third housing portion (230) are sequentially stacked from the bottom. Accordingly, the width of the second hinge structure (250) of the e-type electronic device (101e) may be wider than the width of the first hinge structure (240).

[0086] For example, in a G-type electronic device (101G), the third housing portion (230) may be folded first, and then the first housing portion (210) may be folded later. Unlike an e-type electronic device (101e), the G-type electronic device (101G) may be in a form where the second housing portion (220), the third housing portion (230), and the first housing portion (210) are stacked sequentially from the bottom. Accordingly, the width of the first hinge structure (240) of the e-type electronic device (101e) may be wider than the width of the second hinge structure (250).

[0087] According to one example, when the first hinge structure (240) and the second hinge structure (250) are one in-folding structure and the other out-folding structure, the widths of the first hinge structure (240) and the second hinge structure (250) may be similar or nearly identical. For example, in a z-type electronic device (101z), the first housing part (210) and the third housing part (230) are folded in different directions relative to the second housing part (220), so the width of the hinge structure connecting the housing parts may not be affected. The z-type electronic device (101z) may include a first hinge structure (240) and a second hinge structure (250) with similar or nearly identical widths.

[0088] According to one example, the electronic device (101) may include a foldable housing (201) or a flexible or foldable display (hereinafter abbreviated as "flexible display (203)") (e.g., the display module (160) of FIG. 1) disposed in a space formed by the foldable housing (201). The flexible display (203) may include a first display area (A1), a second display area (A2), a third display area (A3), a first folding area (A4), and a second folding area (A5).

[0089] According to one example, when the electronic device (101) is unfolded (e.g., FIG. 2a to FIG. 2b), the side on which the flexible display (203) is placed (or the side on which the flexible display (203) is visible from the outside of the electronic device (101)) may be defined as the front (201a) of the electronic device (101). When the electronic device (101) is unfolded, the side opposite to the front (201a) may be defined as the rear (201b) of the electronic device (101). Additionally, the side surrounding the space between the front and the rear may be defined as the side of the electronic device (101).

[0090] According to one example, the flexible display (203) is positioned on the front (201a) of the foldable housing (201) and may include a first display area (A1) corresponding to a first housing portion (210), a second display area (A2) corresponding to a second housing portion (220), a third display area (A3) corresponding to a third housing portion (230), a first folding area (A4) corresponding to a first hinge structure (240), and a second folding area (A5) corresponding to a second hinge structure (250).

[0091] In one example, when the foldable housing (201) is fully unfolded, the entire screen of the flexible display (203) can be exposed to the outside. Referring to FIGS. 2a, 3a, and 4a, when the e-type electronic device (101e) and the G-type electronic device (10G) are fully unfolded, the front and rear of the foldable housing (201) are both unfolded, and the entire area (A1, A2, A3, A4, A5) of the flexible display (203) can also be exposed to the outside. When the z-type electronic device (101z) is fully unfolded, the front and rear of the foldable housing (201) are both unfolded, and the entire area (A1, A2, A3, A4, A5) of the flexible display (203) can also be exposed to the outside.

[0092] In one example, when the folding housing (201) is completely folded, the entire area of ​​the flexible display (203) may not be exposed to the outside. For example, referring to FIGS. 2c and 3c, when the e-type electronic device (101e) and the G-type electronic device (10G) are completely folded, the entire screen of the flexible display (203) faces inward and is not exposed to the outside.

[0093] In one example, when the foldable housing (201) is completely folded, a portion of the flexible display (203) may be exposed to the outside. For example, referring to FIG. 4c, when the z-type electronic device (101z) is completely folded, only the first display area (A1) of the flexible display (203) may be exposed to the outside.

[0094] Referring to FIGS. 2a through 3e, the e-type electronic device (101e) and the G-type electronic device (101G) may include a foldable housing (201) or a display (204) (e.g., the display module (160) of FIG. 1) disposed in a part of the space formed by the foldable housing (201). In one example, the display (204) may be disposed on the opposite side of the flexible display (203). For example, the flexible display (203) may be disposed on the front (201a) of the foldable housing (201), and the display (204) may be disposed on the rear (201b) of the foldable housing (201). For example, referring to FIG. 2b, the display (204) may be positioned on the rear of the second housing portion (220) of the e-type electronic device (101e), or referring to FIG. 3b, it may be positioned on the rear of the first housing portion (210) of the G-type electronic device (101G). In one example, the display (204) may be exposed to the outside (e.g., the rear of the housing (201)) when the foldable housing (201) is fully unfolded, and may also be exposed to the outside (e.g., the front of the housing (201)) when the foldable housing (201) is fully folded.

[0095] In one example, the electronic device (101) may not include a display (204) in addition to the flexible display (203). For example, referring to FIGS. 4a through 4e, the z-type electronic device (101z) may include only the flexible display (203) and not the display (204). However, although the z-type electronic device (101z) does not include the display (204), a portion of the flexible display (203) (e.g., a first display area (A1)) may be exposed when it is completely folded.

[0096] In the following, for convenience of explanation, a flexible display (203) that is fully exposed to the outside when the electronic device (101) is fully unfolded may be referred to as the main display, and a display (204) or a part of the flexible display (203) that is always exposed to the outside even when the electronic device (101) is fully folded (e.g., in the case of a z-type electronic device (101z)) may be referred to as the sub display. In various examples, the main display may be suitable for displaying wide-angle images and videos. In various examples, the sub display may be exposed to the outside when the electronic device (101) is unfolded, folded, or in an intermediate state.

[0097] According to one example, the foldable housing (201) may include a flexible display (203) on the front (201a). According to one example, the flexible display (203) may mean a display in which at least a portion of the flexible display (203) can be deformed into a flat or curved surface. For example, the flexible display (203) may be configured to be at least partially folded or at least partially unfolded.

[0098] According to one example, the flexible display (203) may include a first display area (A1), a second display area (A2), a third display area (A3), a first folding area (A4), or a second folding area (A5). The first display area (A1) may be positioned on one side of the first folding area (A4), and the second display area (A2) may be positioned on the other side of the first folding area (A4). The second display area (A2) may be positioned on one side of the second folding area (A5), and the third display area (A3) may be positioned on the other side of the second folding area (A5).

[0099] According to one example, a first display area (A1) may be placed on a first housing portion (210), a second display area (A2) may be placed on a second housing portion (220), and a third display area (A3) may be placed on a third housing portion (230). According to one example, a first folding area (A4) may be placed on a first hinge structure (240) connecting the first display area (A1) and the second display area (A2). A second folding area (A5) may be placed on a second hinge structure (250) connecting the second display area (A2) and the third display area (A3). The division of the flexible display (203) shown in FIGS. 2a to 2b, FIGS. 3a to 3b, and FIGS. 4a to 4b is exemplary, and the display may be divided into multiple regions (e.g., six or more or three) depending on the structure or function.

[0100] According to one example, the flexible display (203) may be combined with or placed adjacent to a touch panel equipped with a touch detection circuit and a pressure sensor capable of measuring the intensity (pressure) of the touch. For example, the flexible display (203) may be combined with or placed adjacent to an electromagnetic induction panel that detects an electromagnetic resonance (EMR) type stylus pen as an example of a touch panel.

[0101] According to one example, the first display area (A1) and the second display area (A2) may have a shape that is symmetrical overall with respect to the first folding area (A4). The second display area (A2) and the third display area (A3) may have a shape that is symmetrical overall with respect to the second folding area (A5).

[0102] According to one example, the first folding region (A4) can be folded inward by an in-folding structure in an e-type electronic device (101e) and a G-type electronic device (101G), and folded outward by an out-folding structure in a z-type electronic device (101z). Below, examples of an in-folding structure and examples of an out-folding structure are described separately. In the examples of the present disclosure, a structure in which the first hinge structure and the second hinge structure are in-folding structures, and the first hinge structure is out-folding and the second hinge structure is in-folding is described, but is not limited thereto.

[0103] According to one example, the electronic device (101) may further include a display (204) in addition to the flexible display (203). The display (204) may be exposed to the outside even when the electronic device (101) is completely folded. The display (204) is positioned opposite to the flexible display (203), and the portion exposed to the user may vary depending on the state of the electronic device (201). In one example, a portion of the flexible display (203) and the display (204) may be exposed together.

[0104] According to one example, the electronic device (101) may include at least one sensor area. Each sensor area may be placed on a foldable housing (201). At least one of an inertial measurement unit (IMU), a digital Hall IC, an illuminance sensor, and a camera (e.g., an image sensor) may be placed in the sensor area.

[0105] In one example, the IMU may be a 3-axis or 6-axis accelerometer or a gyroscope. The electronic device (101) can detect the degree of inclination of the foldable housing (201), more specifically the angle between the housing parts, based on the IMU sensor values. The electronic device (101) may include a 6-axis sensor for each housing part and can determine the angle between the housing parts based on the angle between the 6-axis sensors mounted on each housing. The electronic device (101) can determine the folded state, unfolded state, and degree of fold or unfolded (angle) of the electronic device (101) based on the angle between the first housing part (210) and the second housing part (220) and the angle between the second housing part (220) and the third housing part (230). The electronic device (101) can detect a change in the state of the foldable housing (201) using the IMU sensor. For example, the electronic device (101) can detect a continuous state in which the third housing part (230) is folded or unfolded relative to the second housing part (220) according to a continuous change in the IMU sensor value.

[0106] An electronic device (101) according to one example can determine whether the space between the first housing portion (210) and the second housing portion (220) or between the second housing portion (220) and the third housing portion (230) of the foldable housing (201) is completely unfolded (or open) or completely folded (or closed) based on a digital Hall sensor value. In cases where the electronic device (101) only needs to determine the openness or closeness of the housing portion, it can determine the openness or closeness of the housing portion based on an interrupt occurrence event caused by reaching a threshold value of the digital Hall sensor. The digital Hall sensor may be used to detect the openness or closeness of the foldable housing (201) without accompanying movement of the image sensor. For example, in an e-type electronic device (101e), a digital Hall sensor can be used to detect complete folding (close) / unfolding (open) when the first housing portion (210) is folded or unfolded. Alternatively, in a G-type electronic device (101G), a digital Hall sensor can be used to detect complete folding / unfolding when the third housing portion (230) is folded or unfolded.

[0107] An electronic device (101) according to one example may include a plurality of cameras. Based on the state where the foldable housing (201) is fully folded, it may include a front camera (206) and a rear camera (205). In one example, when the foldable housing (201) is fully unfolded, the front camera (206) and the rear camera (205) may face in the same direction. For example, in an e-type electronic device (101e) and a G-type electronic device (101G), the rear camera (205) may be positioned on the rear of the second housing portion (220) or the third housing portion (230) of the foldable housing (201), and the front camera (206) may be positioned on the front of the display (204) positioned on the rear (201b) of the foldable housing (201), that is, on the rear of the first housing portion (210) or the second housing portion (220) of the foldable housing (201). In one example, when the foldable housing (201) is fully unfolded, the front camera (206) and the rear camera (205) may face in opposite directions. For example, in a z-type electronic device (101z), the rear camera (205) may be positioned on the rear of the third housing portion (230) of the foldable housing (201), and the front camera (206) may be positioned on a portion of the flexible display (203) (e.g., the first housing portion (210)) positioned on the front (201a) of the foldable housing (201).

[0108] In one example, the front camera (206) or rear camera (205) may include one or more lenses, an image sensor and / or an image signal processor. The flash may include, for example, a light-emitting diode or a xenon lamp. In one example, two or more lenses (infrared camera, ultra-wide angle, wide angle, standard and telephoto lenses) and image sensors may be placed on one side of the electronic device (101).

[0109] In one example, the electronic device (101) can display the shooting screens of the rear camera (205) and the front camera (206) on a flexible display (203) or a display (204) divided into multiple windows.

[0110] In one example, the multiple cameras included in the electronic device (101) may differ in type and / or performance. The type and / or performance may differ between the rear camera (205) and the front camera (206), or the type and / or performance may differ between the multiple cameras included in the rear camera (205). The electronic device (101) may consider one of the two cameras as the main shooting and the other as the sub-shooting, and may use the shooting results of the sub-shooting device to correct or expand the results of the main shooting device after shooting. The electronic device (101) can prevent problems that may occur due to performance differences, such as the angle of view (e.g., ultra-wide, wide, standard, or telephoto) and resolution between cameras, when outputting multiple camera images or utilizing them as input information for an artificial intelligence model. For example, if the performance of the rear camera (205) is better than that of the front camera (206), and they are shooting in the same direction, the rear camera (205) can be set as the main camera and the front camera (206) as the sub camera, and a preview image can be displayed using the images acquired by the two cameras. In one example, the electronic device (101) can express various images in a single image by changing the magnification level of each camera or diversifying the target to be focused on. For example, when two cameras are facing the same direction, the camera with relatively lower performance may be used for shooting according to user settings, but the high image quality information of the camera with relatively higher performance may be reflected for a specific part. In various examples, the electronic device (101) can apply various adjustments so that the user perceives the performance difference between multiple cameras as minimal. For example, the electronic device (101) can apply adjustments to image quality, settings of the main camera, diversification of focus, and adjustment of the distance between previews.

[0111] In one example, the rear camera (205) may include a plurality of cameras, and the baseline between each rear camera (205) may be smaller than the baseline between one of the rear cameras (205) and the front camera (206). The depth information obtainable using two cameras may have a first depth information obtainable using one rear camera (205) and the front camera (206) that is deeper than the second depth information obtainable using each rear camera (205). When the rear camera (205) and the front camera (206) are facing the same direction, the shooting screens of the two cameras can be appropriately combined to increase the accuracy of the depth information of the screen and to take a three-dimensional photograph.

[0112] In one example, the field of view of the image that can be captured by the rear camera (205) and / or the front camera (206) and the screen size of the flexible display (203) and / or the display (204) may differ. The electronic device (101) may crop a portion of the preview image to display a wide-angle preview image on a narrow screen.

[0113] According to one example, when the electronic device (101) is fully folded, the front camera (205) can photograph the direction of the user, and the rear camera (205) can photograph the direction opposite to the user. Alternatively, when the electronic device (101) is fully unfolded, both the front camera (206) and the rear camera (205) can photograph the direction opposite to the user. In one example, referring to FIGS. 4a and 4b, even when the z-type electronic device (101z) is fully unfolded, the front camera (206) can photograph the direction of the user, and the rear camera (205) can photograph the direction opposite to the user.

[0114] According to one example, the camera may not be visually exposed. For example, the camera may be configured as an under-display camera (UDC). Pixels in one area of ​​the flexible display (203) corresponding to the location of the UDC may be configured differently from pixels in other areas so that the image sensor and / or camera may not be visually exposed.

[0115] According to one example, a rear camera (205) may be positioned on the rear of the second housing portion (220) or the third housing portion (230) of the foldable housing (201) to generate a first preview image. A front camera (206) may be positioned on the front of the display (204) or the front of the first housing portion (210) to generate a second preview image. The electronic device (101) may determine the user's field of view based on the state of the electronic device (101). The state of the electronic device (101) may be determined based on the angle between the first housing portion (210) and the second housing portion (220) and the angle between the second housing portion (220) and the third housing portion (230). For example, the state of the electronic device (101) may include a first folded state, a first unfolded state, or a first intermediate state by the first housing part (210) and the second housing part (220), and a second folded state, a second unfolded state, or a second intermediate state by the second housing part (220) and the third housing part (230).

[0116] An electronic device (101) according to one example can determine a flexible display (203) or a display (204) that is included in the user's field of view according to the state of the electronic device (101). Depending on the folded or unfolded state of the electronic device (101), the electronic device (101) can display a first preview image and a second preview image, respectively, on the entire flexible display (203), at least a part of the flexible display (203), the entire display (204), or at least a part of the display (204). For example, the electronic device (101) can display a second preview image by the front camera (206) on the display (204) in response to the electronic device (101) detecting a first folded state and a second folded state based on IMU sensor and digital Hall sensor values. Based on IMU sensor and digital Hall sensor values, the electronic device (101) can display a first preview image by the rear camera (205) on a part of the flexible display (203) and a second preview image by the front camera (206) on the display (204) in response to the electronic device (101) detecting a first intermediate state and a second unfolded state based on IMU sensor and digital Hall sensor values.

[0117] In one example, the electronic device (101) can adaptively control a preview image displayed on a flexible display (203) and a display (204) according to a change in the state of the electronic device (101). For example, when the electronic device (101) detects a change in state where the third housing portion (230) is unfolded while the electronic device (101) is fully folded, it can display a first preview image by a rear camera on a third display area (A3) of the flexible display (203).

[0118] According to one example, a key button (207) may be included on one side of a foldable housing (201). The key button (207) may be placed on the left side (e.g., the left side of the first housing part (210)) or the right side (e.g., the right side of the third housing part (230)) of the foldable housing (201). It may be located on the left side or the right side when the foldable housing (201) is fully folded. Depending on the state of the electronic device (101), the key button (207) may be changed to the left side or the right side relative to the user.

[0119] FIG. 5 is a block diagram of a camera provided in an electronic device (e.g., the electronic device (101) of FIG. 1).

[0120] Referring to FIG. 5, a camera (500) (e.g., camera module (180) of FIG. 1) may include a plurality of camera lenses. As an example, the camera (500) may include a first camera lens (510), a second camera lens (520), and a third camera lens (530). FIG. 5 assumes that the camera (500) includes three camera lenses (e.g., a first camera lens (510), a second camera lens (520), and a third camera lens (530)), but this is merely exemplary and may include four or more camera lenses. The first camera lens (510), the second camera lens (520), and the third camera lens (530) may be implemented as one or more modules. For example, the first camera lens (510), the second camera lens (520), and the third camera lens (530) may each be implemented as separate modules. Even when implemented as separate modules, the first camera lens (510), the second camera lens (520), and the third camera lens (530) can be mounted at various locations including the same side and / or different sides in the housing of the electronic device (101).

[0121] Each of the first camera lens (510), the second camera lens (520), and the third camera lens (530) may have a field of view range for photographing a subject. The field of view ranges of the first camera lens (510), the second camera lens (520), and the third camera lens (530) may differ from each other. The first camera lens (510) may have a first field of view range. The second camera lens (520) may have a second field of view range. The third camera lens (530) may have a third field of view range. The first field of view range, the second field of view range, and the third field of view range may differ from each other. According to one example, the first camera lens (510) may support the widest field of view among the cameras included in the electronic device (101). The second camera lens (520) may support a wider field of view than the first camera lens (510). The third camera lens (530) can support a wider field of view than the second camera lens (520). According to one example, the first camera lens (510) may have a field of view corresponding to an ultra-wide camera, the second camera lens (520) may have a field of view corresponding to a wide camera, and the third camera lens (530) may have a field of view corresponding to a telephoto camera. According to one example, the first camera lens (510) may have a field of view corresponding to a wide camera, the second camera lens (520) may have a field of view corresponding to a standard camera, and the third camera lens (530) may have a field of view corresponding to a telephoto camera.

[0122] An ultra-wide-angle camera is, for example, a camera that includes a wide-angle lens with a wide field of view, and the field of view may be about 120 degrees or more. A wide-angle camera may, for example, support a field of view range of 65 degrees to 100 degrees. A standard camera may, for example, include a standard lens that supports a field of view range of about 40 degrees to 65 degrees. A telephoto camera is a camera that includes a telephoto lens for photographing distant subjects, and may support a field of view range of about 10 degrees to 40 degrees and / or about 10 degrees or less. A telephoto lens can, for example, acquire high-quality photos even at magnifications ranging from about 3x zoom to about 30x zoom or more.

[0123] An ultra-wide angle camera may be a camera used to photograph a nearby subject, including an ultra-wide angle lens. An ultra-wide angle camera may be the camera with the widest field of view among the cameras included in the electronic device (101).

[0124] The wide-angle camera may be a camera used for taking general smartphone photos, including a wide-angle lens. The wide-angle camera may be the camera with the second widest field of view among the cameras included in the electronic device (101).

[0125] The standard camera may be a camera used to photograph a subject with a field of view similar to a person's central field of view, including a standard lens. The standard camera may be the camera with the third widest field of view among the cameras included in the electronic device (101).

[0126] The telephoto camera may be a camera used to photograph distant subjects, including a telephoto lens capable of capturing N1 magnification. The telephoto camera may be the camera with the narrowest field of view among the cameras included in the electronic device (101). The camera (500) may additionally include a telephoto camera that supports another magnification, N2 magnification.

[0127] The first camera lens (510), the second camera lens (520), and the third camera lens (530) may be positioned at different locations in the electronic device (101). For example, the first camera lens (510), the second camera lens (520), and the third camera lens (530) may be positioned in the electronic device (101) so as to face the rear, which is opposite to the direction in which the display is looking. For example, at least one of the first camera lens (510), the second camera lens (520), and the third camera lens (530) may be positioned in the electronic device (101) so as to face the rear. For example, at least one of the first camera lens (510), the second camera lens (520), and the third camera lens (530) may be positioned in the electronic device (101) so as to face the front, which is the direction in which the display is looking. For example, the first camera lens (510), the second camera lens (520), and the third camera lens (530) are positioned to face the rear of the electronic device (101), and at least one additional camera lens may be positioned to face the front of the electronic device (101). For example, the camera lens positioned to face the front of the electronic device (101) may have a field of view corresponding to that of the second camera lens (520).

[0128] As an example, the camera (500) may include at least one of a lens assembly, an image sensor, an image stabilizer, a memory (e.g., a buffer memory), or an image signal processor. The lens assembly may collect light emitted from a subject that is the target of the image capture. The image sensor may acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through the lens assembly into an electrical signal. The image stabilizer may move at least one lens or image sensor included in the lens assembly in a specific direction or control the operational characteristics of the image sensor (e.g., adjusting read-out timing, etc.) in response to the movement of the camera (500) or the electronic device (101) including it. The memory may temporarily store at least a portion of the image acquired through the image sensor for the next image processing task. The image signal processor may perform one or more image processing operations on the image acquired through the image sensor or the image stored in the memory. The image signal processor may be configured as at least part of a processor (e.g., processor (120) of FIG. 1) or as a separate processor that operates independently of the processor (120). If the image signal processor is configured as a separate processor from the processor (120), at least one image processed by the image signal processor may be displayed through the display (160) as is or after additional image processing by the processor (120).

[0129] The image sensor may include, for example, one image sensor selected from among image sensors with different properties such as an RGB sensor, a BW (black and white) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same properties, or a plurality of image sensors having different properties. Each image sensor included in the image sensor may be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0130] The image sensor may be configured in a rectangular shape. The length of the image sensor in the Y-axis direction (e.g., vertical direction) may be longer than the length in the X-axis direction (e.g., horizontal direction). In this case, the length in the Y-axis direction of the image acquired through the image sensor (e.g., preview image) may be longer than the length in the X-axis direction. The length in the X-axis direction may be referred to as the horizontal length. The length in the Y-axis direction may be referred to as the vertical length. The image sensor may include multiple unit pixels. The multiple unit pixels may be arranged along the X-axis direction and the Y-axis direction.

[0131] FIG. 6 illustrates examples of execution screens of a camera application provided by an electronic device (e.g., the electronic device (101) of FIG. 1).

[0132] Referring to FIG. 6, the electronic device (101) can run a camera application. When the camera application is run, the electronic device (101) can display the execution screen of the camera application through a display (e.g., the display (160) of FIG. 1). The execution screen of the camera application may include a preview image obtained by a camera (e.g., the camera (180) of FIG. 1). As an example, when the camera application is run, the electronic device (101) can display a preview image obtained by a plurality of camera lenses (e.g., the first to third camera lenses (510, 520, 530) of FIG. 5) on the display (160).

[0133] Referring to the left side of FIG. 6, electronic device A (101) can display an execution screen of a camera application including a preview image (610) through a display (160). In electronic device A (101), the horizontal length of the entire display area of ​​the display (160) may be shorter than the vertical length of the display area of ​​the display (160). Hereinafter, the entire display area of ​​the display (160) may be referred to as the "entire display area." In electronic device A (101), the ratio of the vertical length of the entire display area to the horizontal length of the entire display area may be greater than the ratio of the vertical length of the image sensor to the horizontal length of the image sensor. Electronic device A (101) can obtain a preview image (610) through the image sensor where the vertical length is longer than the horizontal length. Electronic device A (101) can display the horizontal length of the preview image (610) by aligning it with the horizontal length of the entire display area. The electronic device A (101) can display a black area in the area excluding the area where the preview image (610) is displayed in the entire display area.

[0134] Referring to the upper right drawing of FIG. 6, electronic device B (101) can display an execution screen of a camera application including a preview image (620). Electronic device B (101) may have a larger ratio of the horizontal length of the entire display area to the vertical length of the entire display area compared to electronic device A (101). In electronic device B (101), the ratio of the vertical length of the entire display area to the horizontal length of the entire display area may be smaller than the ratio of the vertical length of the image sensor to the horizontal length of the image sensor. Electronic device B (101) can obtain a preview image (620) through the image sensor where the vertical length is longer than the horizontal length. Electronic device B (101) can display the vertical length of the preview image (620) to match the vertical length of the entire display area. Electronic device B (101) can display a black area in the area (621; 623) excluding the area where the preview image (620) is displayed in the entire display area.

[0135] When filling a preview image to fit the width of the entire display area in electronic device B (101), the width of the preview image (620) must be enlarged to fit the width of the entire display area, and at least a portion of the vertical length must be cropped to fit the entire display area. In this case, the resolution of the preview image (620) may be reduced.

[0136] Referring to the bottom right drawing of FIG. 6, electronic device C (101) can display an execution screen of a camera application including a preview image (630). In electronic device C (101), the ratio of the vertical length of the entire display area to the horizontal length of the entire display area may be smaller than the ratio of the vertical length of the image sensor to the horizontal length of the image sensor. Electronic device C (101) can obtain a preview image (630) through the image sensor where the vertical length is longer than the horizontal length. Electronic device C (101) can display the vertical length of the preview image (630) to match the vertical length of the entire display area. Electronic device C (101) can display a black area in the area (631; 633) excluding the area where the preview image (630) is displayed in the entire display area.

[0137] The ratio of the horizontal length of the total display area to the vertical length of the total display area in electronic device C (101) may be larger than that in electronic device B (101). The black area (631; 633) displayed in electronic device C (101) may be larger than the black area (621; 623) displayed in electronic device B (101). As such, as the horizontal length increases while the vertical length of the electronic device (101) remains fixed, the size of the area excluding the area where the preview image is displayed becomes larger.

[0138] When filling a preview image to fit the width of the entire display area in electronic device C (101), the width of the preview image (630) must be enlarged to fit the width of the entire display area, and at least a portion of the vertical length must be cropped to fit the entire display area. In this case, the resolution of the preview image (630) in electronic device C (101) may be reduced compared to when the preview image (620) in electronic device B (101) is enlarged and cropped.

[0139] For example, electronic devices A to C (101) may represent one state of an electronic device (101) comprising a foldable housing including at least one hinge structure and at least two housing parts rotatably coupled by at least one hinge structure. For example, electronic device A (101) may represent a state in which the foldable housing is completely folded (folded state). For example, electronic device B (101) may represent a state in which the electronic device (101) comprising a foldable housing including one hinge structure and two housing parts (601; 602) rotatably coupled by one hinge structure is completely unfolded (unfolded state). For example, the electronic device C (101) may represent a fully unfolded state (unfolded state) of the electronic device (101) including a foldable housing comprising two hinge structures and three housing parts (603; 604; 605) rotatably joined by the two hinge structures.

[0140] FIG. 7 is a flowchart illustrating a method for displaying a preview image in an electronic device according to one example (e.g., the electronic device (101) of FIG. 1).

[0141] In the following examples of operations, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, or at least two operations may be performed in parallel.

[0142] Referring to FIG. 7, the electronic device (101) may display a preview image obtained based on different basic magnifications for each partial display area in operation 710 (see FIG. 8b). A display included in the electronic device (101) (e.g., display (160) of FIG. 1) may include a total display area comprising a plurality of partial display areas (see FIG. 8a). The display (160) may be placed on the front of a foldable housing comprising at least two hinge structures and at least three housing parts rotatably coupled by said at least two hinge structures. The electronic device (101) may be running a camera application that controls a camera (e.g., camera (180) of FIG. 1). The camera (180) may include a plurality of camera lenses that support different magnifications. The preview image may be an image that the user can view in advance via the display before taking a photo or video. The electronic device (101) may set different basic magnifications for each partial display area. The default magnification may be a magnification set by default for each partial display area. The electronic device (101) may acquire a preview image by any one of a plurality of camera lenses based on the default magnification set for each partial display area. The electronic device (101) may display preview images—wherein each of the preview images is acquired by any one of the camera lenses based on a different default magnification—in multiple partial display areas included in the entire display area of ​​the display.

[0143] The electronic device (101) may display a scaling element for each of the multiple partial display areas in operation 730, which can independently scale the preview images displayed in each of the multiple partial display areas (see FIG. 8b). The scaling element may be, for example, a zoom slider. The electronic device (101) may display the scaling element by overlapping it with the preview image. The scaling range for which the scaling can be adjusted for each of the preview images may be set differently through each of the scaling elements. The electronic device (101) may independently adjust the scale of each of the preview images through the scaling elements (see FIG. 8c).

[0144] FIGS. 8a through 8c illustrate a method for displaying a preview image in an electronic device according to one example (e.g., the electronic device (101) of FIG. 1).

[0145] The electronic device (101) can operate in one of a landscape mode and a portrait mode. The landscape mode may be a display mode in which the horizontal length of the display (160) is longer than the vertical length. The portrait mode may be a display mode in which the vertical length of the display (160) is longer than the horizontal length. In FIGS. 8a to 8c, the display mode of the electronic device (101) may be a landscape mode.

[0146] In FIG. 8a, the entire display area may include multiple partial display areas. In FIG. 8a, the entire display area includes three partial display areas, but the number of partial display areas is not limited thereto. For example, a virtual first line (804) and a second line (805) can divide the entire display area (800) into three areas. The area to the left of the first line (804) may be called the first area (810). The area between the first line (804) and the second line (805) may be called the second area (820). The area to the right of the second line (805) may be called the third area (830). The first area (810) has a first length (811) in the horizontal direction. The second area (820) has a second length (812) in the horizontal direction. The third area (830) has a third length (813) in the horizontal direction. The first length (811), the second length (812), and the third length (813) may be substantially the same. The first length (811) and the third length (813) may be substantially the same. The first length (811), the second length (812), and the third length (813) may be different.

[0147] In FIG. 8b, the electronic device (101) may display a preview image obtained based on a different basic magnification for each partial display area. The basic magnification may be preset, for example, within a magnification range that can be adjusted for each partial display area. For example, the electronic device (101) may display a first preview image (801) obtained based on a first basic magnification, a second preview image (802) obtained based on a second basic magnification, and a third preview image (803) obtained based on a third basic magnification in each of the first area (810), the second area (820), and the third area (830). The first basic magnification, the second basic magnification, and the third basic magnification may be different from each other. The first preview image (801) may include a first object (841) corresponding to the subject. The second preview image (802) may include a second object (842) corresponding to the subject. The third preview image (803) may include a third object (843) corresponding to the subject. For example, if the second basic magnification is set higher than the first basic magnification and the third basic magnification is set higher than the second basic magnification, an object included in common in the first preview image (801), the second preview image (802), and the third preview image (803) may be displayed smallest in the first preview image (801), medium size in the second preview image (802), and largest in the third preview image (803).

[0148] The electronic device (101) may display a first magnification element (831) in a first area (810) that can independently adjust the first magnification of a first preview image (801). The electronic device (101) may display a second magnification element (832) in a second area (820) that can independently adjust the second magnification of a second preview image (802). The electronic device (101) may display a third magnification element (833) in a third area (830) that can independently adjust the third magnification of a third preview image (803). The user can independently adjust the first magnification to obtain the first preview image (801) through the first magnification element (831). The user can independently adjust the second magnification to obtain the second preview image (802) through the second magnification element (832). The user can independently adjust the third magnification to obtain the third preview image (803) through the third magnification adjustment element (833).

[0149] For example, in FIG. 8b, if the user independently increases the second magnification through the second magnification adjustment element (832), the electronic device (101) can display a second preview image (822) based on the increased second magnification (see FIG. 8c). In FIG. 8c, the first magnification and the third magnification may be maintained. The size of the second object (852) shown in FIG. 8c may be larger than the size of the second object (842) shown in FIG. 8b. The size of the first object (851) and the third object (853) shown in FIG. 8c, respectively, may be the same as the size of the first object (841) and the third object (843) shown in FIG. 8b, respectively.

[0150] In FIG. 8a through 8c, magnification elements (831; 832; 833) capable of independently adjusting the magnification are each shown in each of the partial display areas (810; 820; 830), but the present disclosure is not limited thereto. Any user interface element capable of controlling the shooting settings of the preview image displayed in the plurality of partial display areas may be displayed in each of the partial display areas.

[0151] FIGS. 9a through 9c illustrate examples of execution screens of a camera application provided by an electronic device (e.g., the electronic device (101) of FIG. 1).

[0152] Referring to FIGS. 9a through 9c, the electronic device (101) may divide the entire display area of ​​the display into a plurality of partial display areas (e.g., three partial display areas) and display a preview image obtained at a different magnification in each of the divided areas. The preview image may be obtained by a camera (e.g., the camera (500) of FIG. 5). As an example, the camera (500) may include a plurality of camera lenses (e.g., the first to third camera lenses (510, 520, 530) of FIG. 5).

[0153] As an example, the entire display area of ​​the electronic device (101) may include a first area, a second area, and a third area. The electronic device (101) may display a first preview image, a second preview image, or a third preview image in each of the first area, the second area, or the third area. The first preview image, the second preview image, and the third preview image may be obtained based on different basic magnifications. For example, the first preview image may be obtained by a first camera lens (510). For example, the first camera lens (510) is suitable for capturing a scene including a building, a landscape, or many people. The second preview image may be obtained by a second camera lens (520). The second camera lens (520) is suitable for capturing a general scene and / or a person, for example. The third preview image may be obtained by a third camera lens (530). The third camera lens (530) may capture a distant subject up close. The third camera lens (530) is suitable for, for example, capturing specific details of the subject.

[0154] The electronic device (101) can display multiple preview images obtained from various cameras before or during video recording through the entire display area. The user can prepare for shooting while checking various shooting angles using the multiple preview images. The electronic device (101) enables simultaneous shooting of the same subject from various perspectives using various cameras. The electronic device (101) can improve the user experience.

[0155] In FIG. 9a, the electronic device (101) can photograph large subjects (910a; 920a; 930a), such as large sculptures or buildings.

[0156] The electronic device (101) can display a first preview image (901a) acquired by a first camera lens (510) in a first area. The first preview image (901a) can capture not only the building (910a) but also the surrounding landscape.

[0157] The electronic device (101) can display a second preview image (902a) acquired by a second camera lens (520) in a second area. The second preview image (902a) can focus more on the building (920a) compared to the first preview image (901a) to show the overall appearance of the building (920a) and / or specific parts of the building (920a) in more detail.

[0158] The electronic device (101) can display a third preview image (903a) acquired by a third camera lens (530) in a third area. The third preview image (903a) can show details (e.g., sculptures, windows) of the building (930a).

[0159] The user can view the beauty of the building from various perspectives using the electronic device (101). The user can also take photos of desired scenes or scenes according to their preferences using the electronic device (101).

[0160] In FIG. 9b, the electronic device (101) can film a concert scene.

[0161] The electronic device (101) can display a first preview image (901b) acquired by a first camera lens (510) in a first area. The first preview image (901b) can capture the overall atmosphere of the concert.

[0162] The electronic device (101) can display a second preview image (902b) acquired by a second camera lens (520) in a second area. The second preview image (902b) can show the artist's performance in more detail by focusing more on the artist on stage compared to the first preview image (901b).

[0163] The electronic device (101) can display a third preview image (903b) acquired by a third camera lens (530) in a third area. The third preview image (903b) can, for example, show the facial expression of a specific artist.

[0164] The user can view the concert scene from various perspectives using the electronic device (101). The user can also film the concert scene or scenes they want according to their preferences using the electronic device (101).

[0165] In FIG. 9c, the electronic device (101) can film a sports game.

[0166] The electronic device (101) can display a first preview image (901c) acquired by a first camera lens (510) in a first area. The first preview image (901c) can capture the entire view of the stadium with a wide field of view.

[0167] The electronic device (101) can display a second preview image (902c) acquired by a second camera lens (520) in a second area. The second preview image (902c) can, for example, contain a game scene including a specific player.

[0168] The electronic device (101) can display a third preview image (903c) acquired by a third camera lens (530) in a third area. The third preview image (903c) can clearly show the movement of a specific player's body part (e.g., hand).

[0169] The user can view sports matches from various perspectives using the electronic device (101). The user can also film desired sports match scenes or scenes using the electronic device (101) according to their preferences.

[0170] FIG. 10 illustrates a method for independently adjusting the magnification for each of the preview images in an electronic device according to one example (e.g., the electronic device (101) of FIG. 1).

[0171] Referring to FIG. 10, the electronic device (101) may display a scaling element (1040; 1050; 1060) for each of the multiple partial display areas (1010; 1020; 1030) that can independently scale preview images displayed in each of the partial display areas. The scaling range of each of the scaling elements (1040; 1050; 1060) may be set differently from one another. The scaling ranges of each of the scaling elements (1040; 1050; 1060) may be set so as not to overlap each other.

[0172] The magnification adjustment element (1040; 1050; 1060) may be a zoom slider that supports fine adjustment of the magnification. The zoom slider (1040; 1050; 1060) may include multiple scales. The multiple scales may correspond to multiple magnifications. For example, the narrower the interval between the scales, the smaller the difference between the magnifications. The magnification adjustment element (1040; 1050; 1060) may support fine adjustment of the magnification through the interval of fine scales. The electronic device (101) may display a magnification handle (1047) on the zoom slider (1040). The magnification handle (1047) may be, for example, a vertical bar (1047) displayed on the zoom slider. The magnification handle (1047) may be at a position corresponding to the currently set magnification. For example, a magnification handle (1047) may be displayed on a specific scale of the zoom slider (1040). The electronic device (101) may display a numeric object (e.g., object (1041)) corresponding to the currently set magnification at the top and / or bottom of the zoom slider (1040).

[0173] The electronic device (101) receives user input for any one of the magnification elements (1040; 1050; 1060) and can independently adjust the magnification of the corresponding preview image in response to the received user input. The user can independently adjust the magnification for each of the preview images by manipulating the magnification elements (1040; 1050; 1060). For example, the user can set the magnification by moving the magnification handle left and right along the zoom slider.

[0174] For example, a plurality of partial display areas may include a first area (1010), a second area (1020), or a third area (1030). The electronic device (101) may display a first magnification element (1040) in the first area (1010). The electronic device (101) may display a second magnification element (1050) in the second area (1020). The electronic device (101) may display a third magnification element (1060) in the third area (1030). The magnification ranges of the first magnification element (1040), the second magnification element (1050), and the third magnification element (1060) may be set differently from each other. The first magnification range of the first magnification element (1040) may be greater than or equal to a first minimum magnification (1041) and less than or equal to a first maximum magnification (1043). The second magnification range of the second magnification element (1050) may be greater than or equal to the second minimum magnification (1051) and less than or equal to the second maximum magnification (1053). The third magnification range of the third magnification element (1060) may be greater than or equal to the third minimum magnification (1061) and less than or equal to the third maximum magnification (1063). The first magnification range, the second magnification range, and the third magnification range may be set so as not to overlap each other. For example, the first magnification range may be set to 0.6x to 0.9x. The second magnification range may be set to 1.0x to 2.9x. The third magnification range may be set to 3.0x to 30x. The first basic magnification of the first area (1010) can be set, for example, to the first minimum magnification (1041) (e.g., 0.6x). The second basic magnification of the second area (1020) can be set, for example, to the second minimum magnification (1051) (e.g., 1.0x). The third basic magnification of the third area (1030) can be set, for example, to the third minimum magnification (1061) (e.g., 3.0x).The electronic device (101) can display a first preview image (801) obtained based on a first basic magnification, a second preview image (802) obtained based on a second basic magnification, and a third preview image (803) obtained based on a third basic magnification in each of the first area (810), the second area (820), and the third area (830).

[0175] The electronic device (101) can adjust the magnification of the first preview image. The electronic device (101) can receive user input (1070). As an example, the electronic device (101) can receive a swipe input (1070) that is released after moving to an area corresponding to a specific magnification (1045) following a long touch input on an area of ​​the first magnification element (1040) (e.g., an area where the magnification handle (1047) is displayed). The swipe input (1070) may be a touch input in which the displacement is greater than the reference magnitude and the speed is faster than the reference speed. A swipe input to the right may indicate 'zoom in'. A swipe input to the left may indicate 'zoom out'.

[0176] The electronic device (101) can adjust the magnification of the first preview image to a specific magnification (1045) in response to user input (1070). In this way, the user can independently adjust the first magnification of the first preview image displayed in the first area (1010) within the first magnification adjustment range by operating the first magnification adjustment element (1040). In the same way, the electronic device (101) can receive user input for the second magnification adjustment element (e.g., swipe input (1080)) and adjust the magnification of the second preview image in response to the received user input. The electronic device (101) can receive user input for the third magnification adjustment element (e.g., swipe input (1090)) and adjust the magnification of the third preview image in response to the received user input. Since the method for scaling the second preview image and / or the method for scaling the third preview image is substantially the same as the method for scaling the first preview image, a detailed explanation thereof is omitted.

[0177] FIGS. 11a through 11d illustrate examples of execution screens of a camera application provided by an electronic device (e.g., the electronic device (101) of FIG. 1).

[0178] Referring to FIGS. 11a through 11d, the electronic device (101) can display a preview image obtained based on different magnifications for each partial display area. The electronic device (101) can display a magnification adjustment element for each partial display area that can independently adjust the magnification for each of the preview images displayed in the plurality of partial display areas. The magnification adjustment range for each of the preview images can be set differently through each of the magnification adjustment elements displayed in the plurality of partial display areas. That is, each magnification adjustment element can support a different magnification adjustment range. In FIGS. 11a through 11d, the entire display area is depicted as including three partial display areas, but the present disclosure is not limited thereto.

[0179] In FIG. 11a, the electronic device (101) can display a preview image obtained based on different basic magnifications for each partial display area. A plurality of partial display areas may include a first area (1110), a second area (1120), or a third area (1130). The electronic device (101) can display a first preview image (1101a) and a first magnification adjustment element (1140) capable of adjusting the magnification of the first preview image in the first area (1110). The electronic device (101) can display a second preview image (1102a) and a second magnification adjustment element (1150) capable of adjusting the magnification of the second preview image in the second area (1120). The electronic device (101) may display a third preview image (1103a) and a third magnification element (1160) capable of adjusting the magnification of the third preview image in a third area (1130). The first magnification element (1140) may support a first magnification range greater than or equal to a first minimum magnification (1141) and less than or equal to a first maximum magnification (1143). The second magnification element (1150) may support a second magnification range greater than or equal to a second minimum magnification (1151) and less than or equal to a second maximum magnification (1153). The third magnification element (1160) may support a third magnification range greater than or equal to a third minimum magnification (1161) and less than or equal to a third maximum magnification (1163). The first preview image (1101a) may be obtained based on a first basic magnification. For example, the first basic magnification may be the first minimum magnification (1141) (e.g., 0.6x). The second preview image (1102a) may be obtained based on the second basic magnification. For example, the second basic magnification may be the second minimum magnification (1151) (e.g., 1.0x). The third preview image (1103a) may be obtained based on the third basic magnification. For example, the third basic magnification may be the third minimum magnification (1161) (e.g., 3.0x).

[0180] The user can independently adjust the magnification of the first preview image (1101a) by operating the first magnification adjustment element (1140) (see FIG. 11b). The user can independently adjust the magnification of the second preview image (1102a) by operating the second magnification adjustment element (1150) (see FIG. 11c). The user can independently adjust the magnification of the third preview image (1103a) by operating the third magnification adjustment element (1160) (see FIG. 11d).

[0181] FIG. 11b illustrates a method of independently adjusting the magnification of a first preview image (1101a) by operating a first magnification adjustment element (1140).

[0182] The electronic device (101) can receive user input (1170). For example, the user input (1170) may be a swipe input (1170) that is released after moving to an area corresponding to a predetermined first magnification (1145) following a long touch input on an area of ​​the first magnification adjustment element (1140). In response to the user input (1170), the electronic device (101) can adjust the magnification of the first preview image from a first base magnification (1141) (e.g., 0.6x) to a predetermined first magnification (1145). The electronic device (101) can acquire a first preview image (1101b) based on the predetermined first magnification (1145) and display the acquired first preview image (1101b) in the first area (1110).

[0183] FIG. 11c illustrates a method of independently adjusting the magnification of a second preview image (1102a) by operating a second magnification adjustment element (1150).

[0184] The method of adjusting the magnification of the second preview image in FIG. 11c is substantially the same as the method of adjusting the magnification of the first preview image in FIG. 11b. For example, the electronic device (101) can adjust the magnification of the second preview image from a second base magnification (1151) (e.g., 1.0x) to a predetermined 2x magnification (1155) in response to user input (e.g., swipe input (1180)). The electronic device (101) can acquire a second preview image (1102c) based on the predetermined second magnification (1155) and display the acquired second preview image (1102c) in a second area (1120).

[0185] FIG. 11d illustrates a method of independently adjusting the magnification of a third preview image (1103a) through a third magnification adjustment element (1160).

[0186] The method for adjusting the magnification of the third preview image in Fig. 11d is substantially the same as or redundant with the method for adjusting the magnification of the first preview image in Fig. 11b, so the explanation is omitted.

[0187] FIGS. 12a to 12e are drawings illustrating user interaction through a scaling element.

[0188] Referring to FIGS. 12a through 12e, the electronic device (101) can display a scaling element for each partial display area that can independently adjust the scaling for each of the preview images displayed in the plurality of partial display areas.

[0189] According to one example, the electronic device (101) may fix the scaling range of at least one of the scaling elements. For example, the scaling range of one of the scaling elements displayed in a plurality of partial display areas may be greater than or equal to a first threshold scaling and less than or equal to a second threshold scaling. The electronic device (101) may provide a feedback signal indicating that a scaling below the first threshold cannot be set in response to user input indicating a scaling below the first threshold. The electronic device (101) may provide a feedback signal indicating that a scaling above the second threshold cannot be set in response to user input indicating a scaling above the second threshold. The user may recognize through the notification that the scaling can be adjusted only within the fixed scaling range. Since the user can select a scaling only within the fixed scaling range, no error occurs in the user's scaling input (e.g., selecting a scaling outside the scaling range).

[0190] According to one example, the electronic device (101) can change the scaling range of at least one of the scaling elements. For example, the electronic device (101) can expand the scaling range of a specific scaling element in response to a specific user input regarding a specific scaling element displayed in a specific partial display area among the partial display areas. If necessary, the user can adjust the scaling of the preview image within the expanded scaling range in the specific partial display area.

[0191] Referring to FIG. 12a, the electronic device (101) can fix at least one scaling range among scaling elements displayed in a plurality of partial display areas. The plurality of partial display areas may include a first area (1210), a second area (1220), or a third area (1230). The electronic device (101) may display a first scaling element (1240), a second scaling element (1250), or a third scaling element (1260) in each of the first area (1210), the second area (1220), or the third area (1230). The first scaling range of the first scaling element (1240) may be greater than or equal to a first minimum scaling (1241) and less than or equal to a first maximum scaling (1243). The second magnification adjustment range of the second magnification adjustment element (1250) may be greater than or equal to the second minimum magnification (1251) and less than or equal to the second maximum magnification (1253). The third magnification adjustment range of the third magnification adjustment element (1260) may be greater than or equal to the third minimum magnification (1261) and less than or equal to the third maximum magnification (1263).

[0192] The electronic device (101) can fix a magnification range of at least one of the magnification elements (1240; 1250; 1260). For example, the electronic device (101) can fix a first magnification range of the first magnification element (1240). The electronic device (101) can provide a feedback signal indicating that a magnification less than the first minimum magnification (1241) cannot be set in response to a user input indicating a magnification less than the first minimum magnification (1241). The electronic device (101) can provide a feedback signal indicating that a magnification greater than the first maximum magnification (1243) cannot be set in response to a user input indicating a magnification greater than the first maximum magnification (1243). For example, the electronic device (101) can fix a third magnification range. The electronic device (101) may provide a feedback signal indicating that a magnification level less than the third minimum magnification level (1261) cannot be set in response to a user input indicating a magnification level less than the third minimum magnification level (1261). The electronic device (101) may provide a feedback signal indicating that a magnification level greater than the third maximum magnification level (1263) cannot be set in response to a user input indicating a magnification level greater than the third maximum magnification level (1263).

[0193] As an example, the electronic device (101) may receive a swipe input that is released after moving to the right of the area corresponding to the first maximum magnification (1243) following a long touch input on an area of ​​the first zoom slider (1240). When the electronic device (101) receives such a swipe input, it may provide a feedback signal for a predetermined time indicating that the first magnification handle (1247) cannot be moved according to the swipe input. For example, the feedback signal may include blinking of the first magnification handle (1247) and / or vibration of the electronic device (101). For example, the electronic device (101) may blink the first magnification handle (1247) in the area corresponding to the first maximum magnification (1243) for a predetermined time. For example, the electronic device (101) can generate vibration while flashing the first magnification handle (1247) in an area corresponding to the first maximum magnification (1243) for a predetermined time.

[0194] As an example, the electronic device (101) may receive a swipe input that is released after moving to the left of the area corresponding to the third minimum magnification (1261) following a long touch input on an area of ​​the third zoom slider (1260). When the electronic device (101) receives such a swipe input, it may provide a feedback signal for a predetermined time indicating that the third magnification handle (1267) cannot be moved according to the swipe input. For example, the feedback signal may include blinking of the third magnification handle (1267) and / or vibration of the electronic device (101). For example, the electronic device (101) may blink the third magnification handle (1267) in the area corresponding to the third minimum magnification (1261) for a predetermined time. For example, the electronic device (101) can generate vibration while flashing the third magnification handle (1267) in an area corresponding to the third minimum magnification (1261) for a predetermined time.

[0195] In FIG. 12b, the electronic device (101) can change the magnification range of at least one of the magnification elements. For example, the electronic device (101) can receive user input (e.g., a swipe input that is released after moving to the right of the area corresponding to the second maximum magnification (1253) following a long touch input on an area of ​​the second zoom slider (1250). When the electronic device (101) receives such swipe input, it can provide a feedback signal for a predetermined time and then expand the second magnification range supported by the second zoom slider (1250) (see bottom of FIG. 12b). For example, the feedback signal may include blinking of the second magnification handle (1257) and / or vibration of the electronic device (101). For example, the electronic device (101) may blink the second magnification handle (1257) and simultaneously generate vibration in the area corresponding to the second maximum magnification (1253) for a predetermined time. The electronic device (101) can extend the second magnification range supported by the second zoom slider (1250) after a predetermined time has elapsed (see bottom of FIG. 12b). The electronic device (101) can extend the length of the second zoom slider (1250). The electronic device (101) can display the extended second zoom slider (1250) across the first area (1210), the second area (1220), and the third area (1230) (see FIG. 12c).

[0196] In FIG. 12c, the electronic device (101) may not display the first zoom slider (1240) and / or the third zoom slider (1260). For example, the electronic device (101) may display the first zoom slider (1240) and / or the third zoom slider (1260) by reducing them to the first area (1210) and the third area (1230), respectively.

[0197] In FIG. 12d, the electronic device (101) can change the magnification range of at least one of the magnification elements. For example, the electronic device (101) can receive user input for the second zoom slider (1250) (e.g., a long touch input (1259) on one area of ​​the second zoom slider (1250)). When the electronic device (101) receives user input, it can extend the second magnification range supported by the second zoom slider (1250) (see bottom of FIG. 12d). The electronic device (101) can extend the length of the second zoom slider (1250). The electronic device (101) can display the extended second zoom slider (1250) across the first area (1210), the second area (1220), and the third area (1230) (see FIG. 12e).

[0198] In FIG. 12e, the electronic device (101) may display the first zoom slider (1240) and / or the third zoom slider (1260) in a reduced size in the first area (1210) and the third area (1230), respectively. For example, the electronic device (101) may not display the first zoom slider (1240) and / or the third zoom slider (1260).

[0199] In FIGS. 12a through 12e, the entire display area is depicted as including three partial display areas, but the present disclosure is not limited thereto.

[0200] Figures 13a and 13b are drawings illustrating user interaction through a scaling element.

[0201] Referring to FIGS. 13a and 13b, the electronic device (101) may lock the magnification of the corresponding preview image to a specific magnification corresponding to a specific area in response to a first user input. The first user input may be a user input regarding a specific area of ​​a magnification adjustment element (1340) displayed in one of the partial display areas. When the electronic device (101) receives a user input to adjust the fixed specific magnification, it may provide a feedback signal indicating that the magnification cannot be adjusted for a predetermined period of time. For example, the feedback signal may include blinking and / or vibration of a magnification handle. The electronic device (101) may unlock the magnification of the corresponding preview image in response to a second user input regarding a specific area. When the lock is released, the electronic device (101) may freely adjust the magnification of the preview image. For example, the plurality of partial display areas may include a first area (1310), a second area (1320), and a third area (1330).

[0202] Referring to FIG. 13a, the electronic device (101) may display a first magnification element (1340) in a first area (1310). The electronic device (101) may display a second magnification element (not shown) in a second area (1320). The electronic device (101) may display a third magnification element (1360) in a third area (1330). The first magnification element (1340) may be a first zoom slider (1340). The second magnification element may be a second zoom slider. The third magnification element (1360) may be a third zoom slider (1360). The electronic device (101) may receive a first user input for a specific area of ​​the first magnification element. A first magnification handle (not shown) may be located in a specific area of ​​the first magnification element. For example, the first user input (1370; 1375) may include a 'swipe up' (1375) input that is released after moving to an upper area of ​​a specific area following a long touch (1370) input on a specific area of ​​the first zoom slider (1340). The swipe up (1375) input may be a touch input in which the displacement is greater than the reference magnitude and the speed is faster than the reference speed. In response to the first user input, the electronic device (101) may lock the magnification of the first preview image displayed in the first area (1310) to a specific magnification (1345).

[0203] Referring to FIG. 13b, the lock can be released in response to a second user input for a specific area corresponding to a specific magnification. The second user input (1380; 1385) may include a 'swipe down' (1385) input that is released after moving to a lower area of ​​the specific area following a long touch (1380) input for a specific area of ​​the first zoom slider (1340). The swipe down (1385) input may be a touch input in which the displacement is greater than the reference magnitude and the speed is faster than the reference speed. The electronic device (101) may release the lock setting for the magnification (1345) of the first preview image displayed in the first area (1310) in response to the second user input.

[0204] In this way, the user can fix and / or unlock the magnification of the first preview image by operating the first magnification adjustment element. In the same manner, the user can fix and / or unlock the magnification of the third preview image by operating the third magnification adjustment element. The electronic device (101) can prevent errors in user input (e.g., incorrect magnification selection) in at least one of the plurality of partial display areas.

[0205] For example, the electronic device (101) cannot lock the magnification of the corresponding preview image to a specific magnification corresponding to a specific area in response to the first user input. For example, the user cannot fix and / or unlock the magnification of the second preview image by operating the second magnification adjustment element. The user can simply adjust the magnification of the second preview image by operating the second magnification adjustment element.

[0206] FIGS. 14a to 14d are drawings for illustrating user interaction through capture elements.

[0207] Referring to FIGS. 14a through 14d, the electronic device (101) may display a capture element for each of the multiple partial display areas that can independently capture each of the multiple preview images displayed in the multiple partial display areas. For example, the multiple partial display areas may include a first area (1410), a second area (1420), and a third area (1430).

[0208] Referring to FIG. 14a, the electronic device (101) may display a first capture element (1440) in the first area (1410) that can independently capture a first preview image displayed in the first area (1410). The electronic device (101) may display a second capture element (1450) in the second area (1420) that can independently capture a second preview image displayed in the second area (1420). The electronic device (101) may display a third capture element (1460) in the third area (1430) that can independently capture a third preview image displayed in the third area (1430). When the electronic device (101) receives user input (e.g., a short touch) for the first capture element (1440), it can capture a first preview image displayed in a first area (1410) where the first capture element (1440) is located. When the electronic device (101) receives user input (e.g., a short touch) for the second capture element (1450), it can capture a second preview image displayed in a second area (1420) where the second capture element (1450) is located. When the electronic device (101) receives user input (e.g., a short touch) for the third capture element (1460), it can capture a third preview image displayed in a third area (1430) where the third capture element (1460) is located.

[0209] The capture elements (1440; 1450; 1460) may be located at the bottom of the entire display area. The position of the capture elements (1440; 1450; 1460) may be fixed. The electronic device (101) may additionally display a floating capture element (1471) in at least one of the plurality of partial display areas. The electronic device (101) may generate the floating capture element (1471) in response to user input for one of the capture elements (1440; 1450; 1460) (e.g., a drag input that is released after moving to any area following a touch input for one of the capture elements (1440; 1450; 1460). When the electronic device (101) receives user input for the floating capture element (1471) (e.g., drag input that is released after moving to an arbitrary area following a touch input for the floating capture element (1471)), it can change the position of the floating capture element (1471). When the electronic device (101) receives user input for the floating capture element (1471) (e.g., a short touch), it can capture a preview image displayed in at least the partial display area where the floating capture element (1471) is located.

[0210] Referring to FIG. 14b, the electronic device (101) can capture one of the preview images (1407) displayed in the plurality of partial display areas in response to user input (e.g., touch input) for one of the capture elements (1440; 1450; 1460) displayed in the plurality of partial display areas. A description of this is omitted as it overlaps with the description of FIG. 14a.

[0211] The electronic device (101) can change the capture element that received the specific user input (e.g., swipe input) into the entire capture element in response to a specific user input (e.g., swipe input) for one of the capture elements (1440; 1450; 1460) displayed in a plurality of partial display areas. The reverse is also possible. The electronic device (101) can change the entire capture element into the capture element corresponding to the corresponding partial display area in response to a specific user input (e.g., swipe input) for the entire capture element. According to one example, the electronic device (101) can receive a swipe input for a second capture element (1450). The electronic device (101) can receive a swipe input (1470) that is released after the touch input for the second capture element (1450) moves to the left. The electronic device (101) can receive a swipe input that is released after the touch input for the second capture element (1450) moves to the right.

[0222] The electronic device (101) can identify a subject based on at least one of preview images displayed in a plurality of partial display areas. According to one example, the electronic device (101) can identify a subject based on one of the preview images displayed in a plurality of partial display areas (e.g., a preview image obtained by a first camera lens (e.g., the first camera lens (510) of FIG. 5). Hereinafter, at least one of the preview images displayed in a plurality of partial display areas is referred to as a 'preview image'. The electronic device (101) can identify a subject included in the preview image using a learning network model of an artificial intelligence (AI) system.

[0223] The electronic device (101) can determine the type of subject included in the preview image. For example, the electronic device (101) can determine whether the subject is a person, an animal, a landscape, a natural object, or food. For example, the electronic device (101) can identify a human face. If the electronic device (101) identifies a human face in the preview image, it can determine that the subject is a person.

[0224] The electronic device (101) can determine the number of subjects. For example, if the subject is a person, the electronic device (101) can determine whether the person included in the preview image is one person or a group including multiple people. If the subject is a group, the electronic device (101) can determine how many people are included in the group.

[0225] The electronic device (101) can determine the main subject by using information regarding the proportion of space occupied by each of the subjects or focus information.

For example, the electronic device (101) can identify the complete appearance of the subject using a learning network model of an artificial intelligence (AI) system. The electronic device (101) can recognize that the subject is cropped if the complete appearance of the subject is not fully contained in the preview image.

[0228] The electronic device (101) can identify whether the subject is horizontal. The horizontality of the subject may mean whether the subject is positioned parallel to a reference line (e.g., ground, horizontal line). The electronic device (101) can identify horizontal structures contained in the subject. For example, the subject may be a building or a long table. For example, the electronic device (101) can identify the roofline of a building or the edge of a long table. The electronic device (101) can identify whether horizontal structures contained in the subject are tilted at an angle greater than a threshold with respect to the reference line.

[0229] The electronic device (101) can identify whether the subject is distorted. For example, the electronic device (101) can identify whether the subject is distorted by analyzing the degree to which straight lines are bent in a preview image. For example, since the first camera lens (the first camera lens (510) of FIG. 5) covers a wide angle of view, it can cause barrel distortion where straight lines bend at the periphery of the lens.

[0230] The electronic device (101) may identify the subject included in the preview image through a server. For example, the electronic device (101) may request the server to identify the subject included in the preview image while transmitting information regarding the preview image (e.g., the preview image or feature information extracted from the preview image) to the server. At this time, the server may identify the subject included in the preview image by analyzing the information regarding the preview image using a learning network model.

For example, the electronic device (101) can determine the recommended shooting composition using a learning network model (e.g., an artificial intelligence model) learned based on expert photographs. For example, the recommended shooting composition may include a recommended shooting magnification. For example, the electronic device (101) can recommend a low shooting magnification if the subject is a landscape or multiple people. For example, the electronic device (101) can recommend a high shooting magnification if the subject is food.

[0234] For example, the electronic device (101) can determine a recommended shooting composition based on the type of identified subject. For example, if the subject is a landscape, the electronic device (101) can determine a magnification level that makes the landscape look stable as a recommended shooting composition (e.g., FIG. 16a). For example, the electronic device (101) can divide the display area into three equal parts horizontally and vertically and determine a magnification level in which the main subject (mountain, tree, or building) is placed at the intersection as a recommended shooting composition.

[0235] For example, the electronic device (101) can determine a recommended shooting composition based on the type and / or number of identified subjects. For example, if the subjects are a group including multiple people, the electronic device (101) can determine a magnification that places the group in the center of the display area as a recommended shooting composition (e.g., FIG. 16b).

[0236] For example, the electronic device (101) can determine a recommended shooting composition based on a main subject.

For example, the electronic device (101) can determine a recommended shooting composition with a magnification that does not cause cropping of the selected main subject in the display area (e.g., FIG. 16e).

[0237] For example, the electronic device (101) can determine a recommended shooting composition based on whether the subject is cropped. For example, if cropping of the subject is identified, the electronic device (101) can determine a magnification that can capture the complete view of the subject as a recommended shooting composition (e.g., FIG. 16c and FIG. 16d).

[0238] For example, the electronic device (101) can determine a recommended shooting composition based on whether the subject is horizontal. For example, if the horizontal line is tilted at an angle greater than a threshold, the electronic device (101) can determine a magnification at which the horizontal line is captured horizontally as a recommended shooting composition (e.g., FIG. 16f).

[0239] For example, the electronic device (101) can determine a recommended shooting composition based on whether the subject is distorted. For example, if a straight line is curved, the electronic device (101) can determine a magnification that does not distort the subject as a recommended shooting composition (e.g., FIG. 16g).

[0240] For example, the electronic device (101) can determine a recommended shooting composition based on information regarding the state of the electronic device. For example, based on information regarding the tilt of the electronic device in the direction of gravity, the electronic device (101) can recognize that the user will take an aerial view. The electronic device (101) can determine the aerial view shooting composition as a recommended shooting composition (e.g., FIG. 16g).

[0241] According to one example, the electronic device (101) may request a recommendation for a shooting composition by transmitting information regarding a preview image and / or information regarding the state of the electronic device to a server. In this case, the server may determine a recommended shooting composition using information regarding the preview image and / or information regarding the state of the electronic device, and transmit information regarding the determined recommended shooting composition to the electronic device (101).

Each of the scaling elements (1740; 1750; 1760) may be a zoom slider. For example, the electronic device (101) may set the first basic scaling range of the first scaling element (1740) to 0.6x or more and 0.9x or less. The electronic device (101) may set the second basic scaling range of the second scaling element (1750) to 1.0x or more and 2.9x or less. The electronic device (101) can set the third basic magnification range of the third magnification element (1750) to 3.0x or more and 30x or less.

[0254] Referring to FIG. 17a, the electronic device (101) can identify a subject based on at least one of preview images (1701a; 1702a; 1703a) displayed in a plurality of partial display areas. The electronic device (101) can obtain information regarding the subject. For example, the electronic device (101) can obtain information that the type of the subject is food. Using information regarding the subject and / or information regarding the electronic device, the electronic device (101) can obtain a recommended shooting composition (e.g., recommended shooting magnification) for at least one of the preview images (1701a; 1702a; 1703a) displayed in the plurality of partial display areas. The electronic device (101) can change the magnification adjustment range of each of the zoom sliders (1740a; 1750a; 1760a) so that the magnification can be adjusted more finely through the zoom sliders (1740a; 1750a; 1760a) based on the recommended shooting composition. For example, the electronic device (101) can automatically change the magnification adjustment range of each of the zoom sliders (1740a; 1750a; 1760a) based on information regarding the acquired subject. For example, the electronic device (101) can display a guide element (1762a) that guides the recommended shooting composition, and when it receives user input (e.g., a long touch) on the guide element (1762a), it can change the magnification adjustment range of each of the zoom sliders (1740a; 1750a; 1760a). According to one example, the electronic device (101) can adjust the magnification range of each of the zoom sliders (1740a; 1750a; 1760a) according to user input.

[0255] For example, if the subject is food, the electronic device (101) may recommend a high shooting magnification. A high shooting magnification has less risk of distortion. The electronic device (101) may change the magnification adjustment range of each of the zoom sliders (1740a; 1750a; 1760a) so that the magnification can be adjusted more finely within the high shooting magnification range. For example, the electronic device (101) may change the first magnification adjustment range (1745a to 1747a) of the first magnification adjustment element (1770a) to 1.1x or more and 2.4x or less. For example, the changed first magnification adjustment range (1745a to 1747a) may be supported by a second camera lens (e.g., the second camera lens (520) of FIG. 5). For example, the electronic device (101) can change the second magnification range (1755a to 1757a) of the second magnification element (1780a) to 2.5x or more and 3.2x or less. For example, the changed second magnification range (1745a to 1747a) may be supported by the second camera lens (520) and / or the third camera lens (e.g., the third camera lens (530) of FIG. 5). For example, the electronic device (101) can change the third magnification range (1765a to 1767a) of the third magnification element (1790a) to 3.5x or more and 30x or less. For example, the changed third magnification range may be supported by the third camera lens (530).

[0256] Referring to FIG. 17b, the electronic device (101) can identify a subject based on at least one of preview images (1701b; 1702b; 1703b) displayed in a plurality of partial display areas. The electronic device (101) can obtain information regarding the subject. For example, the electronic device (101) can obtain information that the type of subject is a large subject (e.g., a building) or a landscape. Using information regarding the subject and / or information regarding the electronic device, the electronic device (101) can obtain a recommended shooting composition (e.g., a recommended shooting magnification) for at least one of the preview images (1701b; 1702b; 1703b) displayed in the plurality of partial display areas. The electronic device (101) can change the magnification adjustment range of each of the zoom sliders (1740b; 1750b; 1760b) so that the magnification can be adjusted more finely through the zoom sliders (1740b; 1750b; 1760b) based on the recommended shooting composition. For example, the electronic device (101) can automatically change the magnification adjustment range of each of the zoom sliders (1740b; 1750b; 1760b) based on information regarding the acquired subject. For example, the electronic device (101) can display a guide element (1742b) that guides the recommended shooting composition on the first zoom slider (1740b), and when it receives user input (e.g., a long touch) on the guide element (1742b), it can change the magnification adjustment range of each of the zoom sliders (1740b; 1750b; 1760b). According to one example, the electronic device (101) can adjust the magnification range of each of the zoom sliders (1740b; 1750b; 1760b) according to user input.

[0257] For example, if the subject is a large subject (e.g., a building) or a landscape, the electronic device (101) may recommend a low shooting magnification. A low shooting magnification may be suitable for capturing the grandeur of a large subject or landscape. The electronic device (101) may change the magnification adjustment range of each of the zoom sliders (1740b; 1750b; 1760b) so that the magnification can be adjusted more finely within the low shooting magnification range. For example, the electronic device (101) may change the first magnification adjustment range (1745b to 1747b) of the first magnification adjustment element (1770b) to 0.6x or more and 0.7x or less. For example, the changed first magnification adjustment range (1745b to 1747b) may be supported by the first camera lens (e.g., the first camera lens (510) of FIG. 5). For example, the electronic device (101) can change the second magnification range (1755b to 1757b) of the second magnification element (1780b) to 0.8x or more and 0.9x or less. For example, the changed second magnification range (1755b to 1757b) can be supported by the first camera lens (510). For example, the electronic device (101) can change the third magnification range (1765b to 1767b) of the second magnification element (1790b) to 1.0x or more and 30x or less. For example, the changed third magnification range (1765b to 1767b) can be supported by the second camera lens (520) and / or the third camera lens (530).

[0258] FIGS. 18a and 18b illustrate acquiring a preview image based on a recommended shooting composition in an electronic device (e.g., the electronic device (101) of FIG. 1).

[0259] Referring to FIGS. 18a and 18b, the electronic device (101) may perform the operation of acquiring images captured by a camera; the operation of acquiring a recommended shooting composition by applying the acquired images to an artificial intelligence model trained to recommend a shooting composition; and the operation of acquiring a preview image to be displayed in at least one of the partial display areas based on the recommended shooting composition. The electronic device (101) may display the acquired preview image in at least one of the partial display areas.

[0260] In FIG. 18a, the electronic device (101) can acquire images (1800) captured by a camera. For example, the electronic device (101) can acquire portraits. The electronic device (101) can acquire recommended shooting compositions by applying the acquired images (1800) to an artificial intelligence model trained to recommend shooting compositions. For example, the electronic device (101) can acquire recommended shooting compositions by using specific images (1815) among the acquired images (1800). The specific images (1815) can be selected by the electronic device (101). The specific images (1815) can be selected by user input. For example, the electronic device (101) can acquire recommended shooting compositions for portraits.

[0261] In FIG. 18b, the electronic device (101) can acquire a preview image (1801) to be displayed in at least one of the partial display areas (1810; 1820; 1830) based on a recommended shooting composition. For example, the electronic device (101) can enter portrait mode. For example, the electronic device (101) can automatically enter portrait mode based on identifying a human face. For example, the electronic device (101) can enter portrait mode upon receiving user input (e.g., selecting portrait mode). When the electronic device (101) enters portrait mode, the electronic device (101) can acquire a preview image (1801) based on a recommended shooting composition. The electronic device (101) can display the preview image (1801) in, for example, the first area (1810). For example, the first area (1810) may support a low magnification adjustment range that is not typically used in portrait mode. For example, the electronic device (101) may display a guide element (1855) in the second area (1820). When user input (e.g., double touch) is received for the guide element (1855), the electronic device (101) may display a preview image (1805) obtained based on the recommended shooting composition in the second area (1820). The second area (1820) may be larger than the first area (1810). The user can view the preview image (1805) with the recommended shooting composition applied in more detail through the second area (1820). For example, when a preview image (1805) is displayed through the second area (1820), the electronic device (101) may display a guide element (1865) in the third area (1830). When the electronic device (101) receives user input regarding the guide element (1865), it may additionally display a preview image obtained based on a recommended shooting composition in the third area (1830).

[0262] FIGS. 19a through 19c illustrate the operation of an electronic device (e.g., the electronic device (101) of FIG. 1).

[0263] Referring to FIGS. 19a through 19c, the electronic device (101) may include a foldable housing. For example, the electronic device (101) may include a foldable housing comprising at least two hinge structures and at least three housings rotatably coupled by said at least two hinge structures. The electronic device (101) may include a first display disposed on the front of the foldable housing. The electronic device may include a second display disposed on the back of a first display portion provided in one of the at least three housings. The electronic device (101) may include a camera disposed on the back of a first display portion provided in one or more of the at least three housings. The entire display area of ​​the first display may include a plurality of partial display areas. The electronic device (101) may display a preview image obtained based on a different basic magnification for each partial display area.

[0264] FIG. 19a is a flowchart illustrating a method for displaying a preview image in an electronic device (101) according to one example.

[0265] In the following examples of operations, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, or at least two operations may be performed in parallel.

[0266] The electronic device (101) can run a camera application in operation 1901. For example, the electronic device (101) may be in a completely folded state.

[0267] The electronic device (101) can identify the state in which the electronic device (101) is fully unfolded in operation 1903. For example, the electronic device (101) may be in landscape mode. Landscape mode may be a display mode in which the horizontal length of the display is longer than the vertical length.

[0268] When the electronic device (101) is fully unfolded, the electronic device (101) can identify whether it is in a mode that displays a vertical preview image in operation 1905. For example, the electronic device (101) may operate in one of a preview image display mode that displays a vertical preview image and a preview image display mode that displays a horizontal preview image. The mode that displays a vertical preview image may be a mode in which a preview image is displayed where the vertical direction is equal to or longer than the horizontal direction. The mode that displays a horizontal preview image may be a mode in which a preview image is displayed where the horizontal direction is longer than the vertical direction. For example, the electronic device (101) may determine the preview image display mode based on user input. For example, the electronic device (101) may provide a user interface for setting the preview image display mode.

[0269] In a mode for displaying a vertical preview image, the electronic device (101) may display a user interface screen containing a preview image obtained based on different basic magnifications for each partial display area in operation 1907. For example, the electronic device (101) may display a user interface screen containing a preview image obtained based on different basic magnifications for each of three partial display areas (1910; 1920; 1930) (see FIG. 19b).

[0270] If the mode is not for displaying a vertical preview image, that is, if the mode is for displaying a horizontal preview image, the electronic device (101) can display a horizontal preview image in operation 1906. For example, the electronic device (101) can display a user interface screen containing a preview image obtained based on a low magnification (see FIG. 19c). For example, the electronic device (101) can crop the top and bottom of the preview image obtained based on a low magnification and display it in the entire display area (1910; 1920; 1930).

[0271] The electronic device (101) may display a zoom slider for each partial display area in operation 1909 (e.g., see FIG. 11a). The electronic device (101) may adjust the magnification of the preview image to be displayed in the partial display area through the zoom slider displayed for each partial display area. For example, the electronic device (101) may display a zoom slider when it receives user input for a basic magnification element displayed on the user interface screen of a camera application (e.g., see FIG. 20a and 20b).

[0272] The electronic device (101) can identify whether, in operation 1911, magnification is performed through a zoom slider displayed in a specific partial display area. For example, the specific partial display area may be an area where the magnification range can be changed (e.g., a second area (1920)).

[0273] When it is identified that magnification is performed through a zoom slider displayed in a partial display area other than a specific partial display area, the electronic device (101) can identify, in operation 1912, whether a magnification outside the magnification range is selected. The partial display area other than the specific partial display area may be, for example, a first area (1910) and / or a third area (1930).

[0274] If a magnification outside the magnification range is selected in a partial display area other than a specific partial display area (e.g., first area (1910); third area (1930)), the electronic device (101) may provide a feedback signal indicating that magnification is not possible in operation 1914.

[0275] When it is identified that magnification is performed through a zoom slider displayed in a specific part display area (1920), the electronic device (101) can identify whether a magnification outside the magnification range is selected in operation 1913.

[0276] When a scale outside the scale adjustment range is selected in a specific partial display area (1920), the electronic device (101) may change the scale adjustment range in operation 1915 and provide a feedback signal indicating that the scale adjustment range has been changed.

[0277] A detailed description of operations 1911 to 1915 is omitted as it is identical to or redundant with the description in FIGS. 12a to 12e.

[0278] FIGS. 20a and 20b illustrate examples of execution screens of a camera application provided by an electronic device (e.g., the electronic device (101) of FIG. 1).

[0279] In FIG. 20a and 20b, the electronic device (101) may include a foldable housing. For example, the electronic device (101) may include a foldable housing comprising at least two hinge structures and at least three housings rotatably coupled by said at least two hinge structures. The electronic device (101) may include a first display disposed on the front of the foldable housing. The electronic device may include a second display disposed on the back of a first display portion provided in one of the at least three housings. The electronic device (101) may include a camera disposed on the back of a first display portion provided in one or more of the at least three housings. The entire display area of ​​the first display may include a plurality of partial display areas. The electronic device (101) may display a preview image obtained based on a different basic magnification for each partial display area.

[0280] Referring to the left side of FIG. 20a, when a camera application is executed while the electronic device (101) is in a completely folded state, the electronic device (101) can display a preview image (2000) through a second display.

[0281] Referring to the middle drawing of FIG. 20a, when the electronic device (101) is fully unfolded while displaying a preview image (2000) through a second display, the electronic device (101) can display the preview image obtained based on different basic magnifications for each partial display area. For example, the partial display areas may include a first area (2010), a second area (2020), and a third area (2030). The electronic device (101) may include a first preview image (2001), a second preview image (2002), and a third preview image (2003) in each of the first area (2010), the second area (2020), and the third area (2030). The electronic device (101) may display a basic scaling element (2070) in at least one of a plurality of partial display areas (e.g., a first area (2010), a second area (2020), and a third area (2030)). For example, the electronic device (101) may display the basic scaling element (2070) in the first area (2010) and the third area (2030). The basic scaling element (2070) may be a scaling bar comprising a plurality of objects (2071; 2073; 2075) corresponding to a plurality of scaling levels. The electronic device (101) may identify user input (e.g., a long touch) for the basic scaling element (2070).

[0282] Referring to FIG. 20b, the electronic device (101) may display zoom sliders (2040; 2050; 2060) for each partial display area in response to user input (e.g., long touch) on a basic scaling element (2070). Refer to FIG. 10 for a description of the zoom sliders.

[0283] FIGS. 21a through 21d illustrate an exemplary method of displaying a preview image in an electronic device (e.g., the electronic device (101) of FIG. 1).

[0284] In FIG. 21a, the electronic device (101) may include a foldable housing. For example, the electronic device (101) may include a foldable housing comprising at least two hinge structures and at least three housings rotatably coupled by said at least two hinge structures. The electronic device (101) may include a first display disposed on the front of the foldable housing. The electronic device may include a second display disposed on the back of a first display portion provided in one of the at least three housings. The electronic device (101) may include a camera (e.g., camera (180) of FIG. 1) disposed on the back of a first display portion provided in one or more of the at least three housings. The entire display area of ​​the first display may include a plurality of partial display areas.

[0285] When the folding housing is in a completely folded state while the electronic device (101) is running a camera application, it can display a predetermined preview image acquired by the camera through a second display. When the folding housing is in a completely unfolded state while the predetermined preview image is being displayed through the second display, the electronic device (101) can acquire at least one of the preview images to be displayed in a plurality of partial display areas included in the entire display area of ​​the first display based on a magnification equal to that of the predetermined preview image. According to one example, when the electronic device (101) runs a camera application while the folding housing is in a completely unfolded state, it can display a preview image acquired based on a different basic magnification for each partial display area (e.g., see FIG. 11a).

[0286] When the foldable housing is fully unfolded while the electronic device (101) is displaying a predetermined preview image through a second display, the layout of the plurality of partial display areas can be determined according to the aspect ratio of the predetermined preview image. The number of partial display areas may be, for example, three. For example, the electronic device (101) can determine a layout including a center area having the same aspect ratio as the aspect ratio of the preview image, and a left area and a right area excluding the center area.

[0287] The electronic device (101) may operate in one of two modes: a black area display mode and a black area non-display mode. For example, the electronic device (101) may provide a user interface screen that allows the user to determine whether to display the black area or the black area non-display mode. For example, if the user selects the black area display mode, the electronic device (101) may display a preview image along with the black area. For example, the electronic device (101) may display a preview image in each of a plurality of partial display areas and display a black area in the area where the preview image is not displayed. For example, if the user selects the black area non-display mode, the electronic device (101) may display a preview image in each of a plurality of partial display areas without displaying the black area. For example, the electronic device (101) may be set to the black area display mode by default. The electronic device (101) may remove the black area in response to user input (an event to remove the black area) selecting the black area non-display mode. For example, the electronic device (101) can obtain a preview image corresponding to the partial display area where the black area is removed in response to an event to remove the black area.

[0288] For example, in black area display mode, the electronic device (101) can determine the vertical length of the preview image based on the horizontal length and aspect ratio of the partial display area. The electronic device (101) can display a preview image having a size of horizontal length * vertical length for each partial display area and display a black area in the remaining area.

[0289] In the black area non-display mode, the electronic device (101) can determine the width of the preview image based on the vertical length and aspect ratio of the partial display area. The electronic device (101) can acquire a preview image having a size of width * vertical length and crop the acquired preview image to fit the partial display area.

[0290] Referring to the lower left drawing of FIG. 21a, when a camera application is executed with the foldable housing fully folded, the electronic device (101) can display a preview image (2104) acquired by the camera (180) through a second display. For example, the aspect ratio of the preview image (2104) displayed on the second display may be a:b (horizontal length: vertical length) (e.g., 9:16, 3:4, 1:1). For example, the electronic device (101) can display a black area in the area (2145; 2147) excluding the area where the preview image (2104) is displayed from the entire display area of ​​the second display.

[0291] Referring to the center drawing at the bottom of FIG. 21a, the electronic device (101) may be in a black area display mode. When the foldable housing is fully unfolded while the electronic device (101) is displaying a preview image (2104) through the second display, the electronic device (101) may display a preview image obtained based on a different basic magnification for each partial display area. The electronic device (101) may obtain at least one of the preview images to be displayed in a plurality of partial display areas based on a magnification equal to that of a predetermined preview image. The electronic device (101) may determine the layout of the plurality of partial display areas on the first display according to the aspect ratio of the preview image displayed through the second display. Based on the determined layout, the electronic device (101) may display a black area along with the preview image in at least one of the plurality of partial display areas.

[0292] The top drawing of FIG. 21a shows an exemplary layout of multiple partial display areas. A virtual first line (2104) and a second line (2105) can divide the entire display area (2100) into three areas. The area to the left of the first line (2104) can be called the first area (2110). The area between the first line (2104) and the second line (2105) can be called the second area (2120). The area to the right of the second line (2105) can be called the third area (2130). The entire display area has a total horizontal length (2100) in the horizontal direction. The entire display area has a total vertical length (2106) in the vertical direction. The first area (2110) has a first length (2111) in the horizontal direction. The second area (2120) has a second length (2112) in the horizontal direction. The third region (2130) has a third length (2113) in the horizontal direction. The sum of the first length (2111), the second length (2112), and the third length (2113) may be substantially equal to the total horizontal length. The first length (2111), the second length (2112), and the third length (2113) may be substantially the same. The first length (2111) and the third length (2113) may be substantially the same, but different from the second length (2112). The first length (2111), the second length (2112), and the third length (2113) may be different from each other.

[0293] For example, the aspect ratio of the preview image (2104) displayed on the second display may be a:b. The electronic device (101) may determine the layout of multiple partial display areas according to the aspect ratio a:b. For example, the electronic device (101) may determine the aspect ratio of one of the multiple partial display areas to be a:b. For example, the electronic device (101) may place one area having an aspect ratio of a:b at the center of the entire display area. For example, the electronic device (101) may determine the ratio of the second area (2120) to be a:b. The electronic device (101) may place the second area (2120) at the center of the entire display area. The electronic device (101) may determine a layout including the first area (2110) and the third area (2130), excluding the second area (2120) from the entire display area. The ratio of the first area (2110) and the third area (2130) may not be a:b. For example, the ratio of the first area (2110) and the third area (2130) may be a ratio where the vertical length is longer than a:b, such as a:c or a:d (e.g., c > b, d > b). The electronic device (101) may determine the aspect ratio of all preview images to be displayed through the first display to be the same as the aspect ratio a:b displayed on the second display. The electronic device (101) may display preview images having an aspect ratio a:b in the first area (2110), the second area (2120), and the third area (2130), respectively. The electronic device (101) may display a second preview image (2102) having an aspect ratio a:b in the second area (2120). The second preview image (2102) can fill the entire second area (2120). The electronic device (101) can display a first preview image (2101) having an aspect ratio a:b in the first area (2110) along with a black area. The first preview image (2101) may not fill the entire first area (2110).The electronic device (101) can determine the first vertical length (2108) of the first preview image (2101) based on the aspect ratio a:b and the first horizontal length (2111). The first vertical length (2108) may be the value obtained by multiplying the first horizontal length (2111) by b / a. The electronic device (101) can display the first preview image (2101) in an area having a size of the first horizontal length (2111) * first vertical length (2108) in at least a part of the first area (2110). The electronic device (101) can display a black area (2115; 2117) in the area excluding the area where the first preview image (2101) is displayed in the first area (2130). The electronic device (101) can display a third preview image (2103) having an aspect ratio a:b in a third area (2130) along with a black area. Since the method of displaying the third preview image (2103) is the same as the method of displaying the first preview image (2101), a detailed description is omitted.

[0294] Referring to the bottom right drawing of FIG. 21a, the electronic device (101) may be in a black area non-display mode. When the foldable housing is fully unfolded while the electronic device (101) is displaying a preview image (2104) through the second display, the electronic device (101) may display a preview image obtained based on a different basic magnification for each partial display area. The electronic device (101) may obtain at least one of the preview images to be displayed in a plurality of partial display areas based on a magnification equal to that of a predetermined preview image. The electronic device (101) may determine the layout of the plurality of partial display areas on the first display according to the aspect ratio of the preview image displayed through the second display. Based on the determined layout, the electronic device (101) may display a preview image in each of the plurality of partial display areas without displaying a black area.

[0295] For example, the aspect ratio of the preview image (2104) displayed on the second display may be a:b. The electronic device (101) may determine the layout of multiple partial display areas according to the aspect ratio a:b (see the top drawing of FIG. 21a).
