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

[0036] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

[0041] FIG. 2a is a drawing illustrating a structure of an electronic device in an unfolded state according to one embodiment, and FIG. 2b is a drawing illustrating a structure of an electronic device in a folded state according to one embodiment.

[0042] Referring to FIGS. 2A and 2B, an electronic device (101) according to an embodiment is a foldable electronic device, and may include a hinge structure (e.g., a hinge structure (230) of FIG. 2B) (e.g., a hinge cover) covering a foldable portion of a housing (200), and a first display (161) (e.g., a display module (160) of FIG. 1) in a flexible or foldable form disposed within a space formed by the housing (200). According to an embodiment, the electronic device (101) may include a second display (163) disposed on a part of the housing (200) on an opposite side to which the first display (161) is disposed. According to an embodiment, the side on which the first display (161) is disposed is defined as a first side (e.g., a front side) of the electronic device (101). And, the side opposite to the first side is defined as the second side (e.g., the back) of the electronic device (101). In addition, the side surrounding the space between the first side and the second side is defined as the third side (e.g., the side) of the electronic device (101). The second display (163) may be smaller in size than the first display (161).

[0043] According to one embodiment, the housing (200) may include a first housing structure (210), a second housing structure (220) including a sensor area (224), a first rear cover (280), a second rear cover (290), and a hinge structure (230). The housing (200) of the electronic device (101) is not limited to the shape and combination shown in FIGS. 2A and 2B, and may be implemented by other shapes or combinations and / or combinations of parts. For example, in another embodiment, the first housing structure (210) and the first rear cover (280) may be formed integrally, and the second housing structure (220) and the second rear cover (290) may be formed integrally.

[0044] According to one embodiment, the first housing structure (210) and the second housing structure (220) may be arranged on both sides with respect to a folding axis (e.g., the folding axis (A) of FIG. 2A) as the center, and may have a shape that is overall symmetrical with respect to the folding axis (A). As described below, the angle or distance between the first housing structure (210) and the second housing structure (220) may vary depending on whether the state of the electronic device (101) is in an unfolded state, a folded state, or a partially unfolded intermediate state. According to one embodiment, unlike the first housing structure (210), the second housing structure (220) additionally includes a sensor area (224) in which various sensors are arranged, but may have a shape that is symmetrical with respect to the other areas.

[0045] According to one embodiment, the first housing structure (210) and the second housing structure (220) are connected to a hinge structure (230) and can be folded or unfolded by rotating about the hinge structure (230). Accordingly, the electronic device (101) can be changed into a folded state or an unfolded state. The electronic device (101) can be changed from an unfolded state as shown in FIG. 2A to a folded state (e.g., an in-folded state as shown in FIG. 2B) in which the first side of the first housing structure (210) and the third side of the second housing structure (220) come closer to each other and face each other. The electronic device (101) can be converted from an unfolded state as shown in FIG. 2A to a folded state (e.g., an out folded state) in which the second side of the first housing structure (210) faces the fourth side of the second housing structure (220) while approaching each other.

[0046] According to one embodiment, as illustrated in FIG. 2A, the first housing structure (210) and the second housing structure (220) may together form a recess that accommodates the first display (161). According to one embodiment, due to the sensor area (224), the recess may have two or more different widths in a direction perpendicular to the folding axis (A). According to one embodiment, the recess may have a first width (w1) between a first portion (210a) of the first housing structure (210) that is parallel to the folding axis (A) and a first portion (220a) formed at an edge of the sensor area (224) of the second housing structure (220), and the recess may have a second width (w2) formed by a second portion (210b) of the first housing structure (210) and a second portion (220b) of the second housing structure (220) that is parallel to the folding axis (A) and does not correspond to the sensor area (224). In this case, the second width (w2) may be formed to be longer than the first width (w1). As another example, the first part (210a) of the first housing structure (210) and the first part (220a) of the second housing structure (220) having mutually asymmetrical shapes may form a first width (w1) of the recess, and the second part (210b) of the first housing structure (210) and the second part (220b) of the second housing structure (220) having mutually symmetrical shapes may form a second width (w2) of the recess. In one embodiment, the first part (220a) and the second part (220b) of the second housing structure (220) may have different distances from the folding axis (A). The width of the recess is not limited to the illustrated example. In another embodiment, the recess may have a plurality of widths due to the shape of the sensor area (224) or the asymmetrical shapes of the first housing structure (210) and the second housing structure (220).

[0047] According to one embodiment, at least a portion of the first housing structure (210) and the second housing structure (220) may be formed of a metallic or non-metallic material having a rigidity of a selected size to support the first display (161). At least a portion formed of the metallic material may provide a ground plane of the electronic device (101) and may be electrically connected to a ground line formed on a printed circuit board.

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

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

[0050] According to one embodiment, the first rear cover (280) and the second rear cover (290) may have substantially symmetrical shapes with respect to the folding axis (A axis). However, the first rear cover (280) and the second rear cover (290) do not necessarily have mutually symmetrical shapes, and in another embodiment, the electronic device (101) may include the first rear cover (280) and the second rear cover (290) of various shapes. In another embodiment, the first rear cover (280) may be formed integrally with the first housing structure (210), and the second rear cover (290) may be formed integrally with the second housing structure (220).

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

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

[0053] Referring to FIG. 2b, the hinge structure (230) may be configured to be positioned between the first housing structure (210) and the second housing structure (220) so as to cover internal components. According to one embodiment, the hinge structure (230) may be covered by a part of the first housing structure (210) and the second housing structure (220) or exposed to the outside, depending on the folding state (unfolded state, intermediate state, or folded state) of the electronic device (101). According to one embodiment, as shown in FIG. 2A, when the electronic device (101) is in an unfolded state, the hinge structure (230) may be covered by the first housing structure (210) and the second housing structure (220) and not exposed. As another example, as shown in FIG. 2B, when the electronic device (101) is in a folded state (e.g., a fully folded state), the hinge structure (230) may be exposed to the outside between the first housing structure (210) and the second housing structure (220). As another example, the first When the housing structure (210) and the second housing structure (220) are in an intermediate state where they are folded at a certain angle, the hinge structure (230) may be partially exposed to the outside between the first housing structure (210) and the second housing structure (220). However, in this case, the exposed area may be less than that in the completely folded state. In one embodiment, the hinge structure (230) may include a curved surface.

[0054] According to one embodiment, the first display (161) may be disposed on a space formed on a first surface of the first housing structure (210) and a third surface of the second housing (220). According to one embodiment, the second display (163) may be disposed on a space formed on a second surface of the first housing structure (210) or a fourth surface of the second housing structure (220). For example, the first display (161) may be mounted on a recess formed by the housing (200) and may constitute most of the front surface of the electronic device (101). According to one embodiment, the first display (161) may mean a display in which at least a portion of the display can be transformed into a flat or curved surface. According to one embodiment, the first display (161) may include a folding area (203), a first display area (201) disposed in a first housing structure (210) on one side (e.g., the left side of the folding area (203) illustrated in FIG. 2A) with respect to the folding area (203), and a second display area (202) disposed in a second housing structure (220) on the other side (e.g., the right side of the folding area (203) illustrated in FIG. 2A).

[0055] However, the division of the regions of the first display (161) illustrated in FIG. 2A is exemplary, and the first display (161) may be divided into a plurality of regions (for example, four or more or two) depending on the structure or function. For example, in the embodiment illustrated in FIG. 2A, the regions of the first display (161) may be divided by a folding region (203) extending parallel to the y-axis or a folding axis (A-axis), but in other embodiments, the first display (161) may be divided into regions based on another folding region (for example, a folding region parallel to the x-axis) or another folding axis (for example, a folding axis parallel to the x-axis). According to one embodiment, the first display (161) and the second display (163) may be combined with or disposed adjacent to a touch detection circuit, a pressure sensor capable of measuring the intensity (pressure) of a touch, and / or a digitizer that detects a magnetic field-type stylus pen.

[0056] According to one embodiment, the first display area (201) and the second display area (202) may have an overall symmetrical shape centered on the folding area (203). However, unlike the first display area (201), the second display area (202) may include a cut notch depending on the presence of the sensor area (224), but may have a shape symmetrical with respect to the first display area (201) in other areas. In other words, the first display area (201) and the second display area (202) may include a portion having a symmetrical shape and a portion having an asymmetrical shape.

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

[0058] According to one embodiment, when the electronic device (101) is in an unfolded state (e.g., the unfolded state of FIG. 2A), the first housing structure (210) and the second housing structure (220) may be arranged to form an angle of 180 degrees and face the same direction. The surface of the first display area (201) of the first display (161) and the surface of the second display area (202) may form an angle of 180 degrees with each other and face the same direction (e.g., toward the front of the electronic device). The folding area (203) may form the same plane as the first display area (201) and the second display area (202).

[0059] According to one embodiment, when the electronic device (101) is in a folded state (e.g., the folded state of FIG. 2B), the first housing structure (210) and the second housing structure (220) may be arranged to face each other. The surface of the first display area (201) of the first display (161) and the surface of the second display area (202) may form a narrow angle (e.g., between 0 and 10 degrees) with each other and may face each other. The folding area (203) may be formed as a curved surface having at least a portion of a predetermined curvature.

[0060] According to one embodiment, when the electronic device (101) is in a folded state, the first housing structure (210) and the second housing structure (220) may be arranged at a certain angle with respect to each other. The surface of the first display area (201) of the first display (161) and the surface of the second display area (202) may form an angle that is larger than the angle in the folded state and smaller than the angle in the unfolded state. The folding area (203) may be formed as a curved surface having at least a certain curvature, and the curvature at this time may be smaller than that in the folded state.

[0061] According to one embodiment, the electronic device (101) may include an in-folding type or an out-folding type. The in-folding type may refer to a state in which the flexible first display (161) is not exposed to the outside in a fully folded state. As another example, the first display (161) may refer to a state in which the first display (161) is folded in a front direction. The out-folding type may refer to a state in which the first display (161) is visually exposed to the outside in a fully folded state. As another example, the first display (161) may refer to a state in which the first display (161) is folded in a rear direction. For example, the electronic device (101) may display a multi-window in an unfolded state (e.g., the unfolded state of FIG. 2A).

[0062] Although the above FIGS. 2A and 2B illustrate an example in which the display area is expanded through a flexible display, that is, the display area is enlarged, the electronic device may have a display area that is expanded using a rollable display, or may have a display area of ​​a size that allows multi-window display without being flexible or rollable.

[0063] FIG. 3 is a drawing illustrating a state in which a plurality of cameras are arranged in two rows on the rear area of ​​a second housing of an electronic device according to one embodiment.

However, the electronic device (101) according to an embodiment may further include other components described in FIG. 1.

[0065] According to one embodiment, an electronic device may place a front camera (24) on a portion of the front corresponding to a third side of a second housing (e.g., a second housing (220) of FIG. 2A) of the electronic device (or a first side of a first housing (e.g., a first housing (210) of FIG. 2A)) of the electronic device when the electronic device is in an unfolded state (e.g., an electronic device (101) of FIG. 2A), and the front camera (24) may include an Under-Display Camera (UDC).

[0066] According to one embodiment, an electronic device may have a plurality of rear cameras (393) and a front cover camera (383) arranged in each of a portion of the rear surface corresponding to a second surface of a first housing (e.g., a first housing (210) of FIG. 2A) and a fourth surface of a second housing (e.g., a second housing (220) of FIG. 2A) of the electronic device in an unfolded state (e.g., an electronic device (101) of FIG. 2A).

[0068] According to one embodiment, a "stereo image" may be used to mean a pair of 2D images that are images acquired through two or more cameras and allow the perception of a three-dimensional stereoscopic effect (depth) by utilizing the difference in visual acuity of both eyes. For example, the stereo image may include a left-eye image corresponding to the left eye and a right-eye image corresponding to the right eye. According to one embodiment, the stereo image may be played back through an electronic device developed to be wearable by a user (e.g., a wearable electronic device such as an augmented reality glass (AR glass), a video see-through (VST) device, or a head-mounted display (HMD) device) and displayed to the user in the form of a 3D image. The stereo image may also be replaced with the term "spatial video," but is not limited to a specific term.

[0069] According to one embodiment, the camera may include a plurality of cameras, and among the plurality of cameras, a front cover camera (383) may be disposed on a second side (e.g., front) of the first housing, and among the plurality of cameras, a plurality of rear cameras (393) may be disposed on a fourth side (e.g., rear) of the second housing. For example, when the electronic device is placed in a vertical direction (the direction illustrated in FIG. 2A), a stereo image may be captured using any one of the plurality of rear cameras and the front cover camera (383).

[0071] According to one embodiment, when a plurality of rear cameras included in a second rear area (292) of a second rear cover (e.g., 290 of FIG. 2A) of an electronic device, such as FIG. 3, include a plurality of first rear cameras (393) arranged in two rows and at least one second rear camera (394), the plurality of first rear cameras (393) in the first row may be an ultra-wide-angle camera (393-1), a wide-angle camera (393-2), and a telephoto camera (393-3), and at least one second rear camera (394) in the second row may be a telephoto camera.

[0072] According to one embodiment, when the electronic device is in a foldable form, as illustrated in FIGS. 2A and 3 , when the electronic device is fully unfolded, the front cover camera (383) and the plurality of rear cameras (393 and / or 394) may face the same direction. Accordingly, a stereo image may be acquired using at least one camera among the front cover camera (383) and the plurality of rear cameras (393 and / or 394).

[0073] According to one embodiment, in the embodiments described below, for the convenience of explanation, among the multiple cameras used for stereo image shooting, the multiple rear cameras (393) may be set as cameras corresponding to the right eye, and the front cover camera (383) may be set as a camera corresponding to the left eye. According to one embodiment, the multiple rear cameras (393 and / or 394) may be set as cameras corresponding to the left eye, and the front cover camera (383) may be set as a camera corresponding to the left eye.

[0074] According to one embodiment, the electronic device may acquire a first image through at least one of the plurality of rear cameras (393 and / or 394) and a second image through the front rear camera (383) based on receiving a user input for capturing a stereo image. According to one embodiment, the electronic device may acquire a left-eye image and a right-eye image of the stereo image based on the first image and the second image.

[0075] The electronic device can display an image set for a preview image among the first image and the second image (e.g., the first image or the second image) as a preview image through a display (e.g., a flexible display).

[0076] According to one embodiment, the electronic device can store data of the stereo image acquired based on the first image and the second image in a memory.

[0080] The third camera may be positioned adjacent to the first camera positioned on the fourth surface.

[0081] According to an embodiment, the electronic device may further include at least one second sensor for sensing folding angles of the first housing and the second housing. According to an embodiment, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to acquire a stereo image through the first camera and the third camera among the plurality of cameras based on the sensed inclination being included in the second range and the folding angle sensed through the second sensor being included in the first range.

[0083] According to one embodiment, the electronic device may further include at least one second sensor for sensing folding angles of the first housing and the second housing.

[0089] FIG. 4 is a flowchart illustrating an operation of selecting two cameras for generating a stereo image based on a tilt of an electronic device, according to one embodiment.

[0090] Referring to FIG. 4, in one embodiment, in operation 410, an electronic device (e.g., the electronic device (101) of FIG. 1, the processor (120) of FIG. 1, the electronic device (101) of FIG. 2A) may sense an inclination of the electronic device through at least one sensor based on receiving a user input for stereo image capturing.

[0091] According to one embodiment, when a user input (e.g., a touch input or a voice input) for capturing a stereo image is received through the execution screen of a camera application, the electronic device may sense an inclination of the electronic device through at least one sensor (e.g., the sensor module (176) of FIG. 1) that senses an inclination of the electronic device. For example, the at least one sensor may include at least one of a gyro sensor and an acceleration sensor.

[0092] In one embodiment, in operation 420, the electronic device may select two cameras from among the plurality of rear cameras based on the sensed tilt being within a first range, and may select two cameras arranged in a second direction different from the first direction from among the plurality of rear cameras and the front cover camera based on the sensed tilt being within a second range different from the first range.

[0093] For example, a first range may include a range greater than 90 degrees and less than 180 degrees, and a second range may include a range greater than or equal to 0 degrees and less than or equal to 90 degrees.

[0094] According to one embodiment, the front cover camera may be disposed on a second side of a first housing (e.g., the first housing structure (210) of FIG. 2A or the first housing structure (210) of FIG. 2B), and the plurality of rear cameras may be disposed on a fourth side of a second housing (e.g., the second housing structure (220) of FIG. 2A or the second housing structure (220) of FIG. 2B).

[0095] According to one embodiment, the electronic device may select two cameras based solely on the inclination of the electronic device within a plane defined by the x-axis and the y-axis in the coordinate system illustrated in FIG. 2A. For example, the electronic device may select two cameras corresponding to the left and right eyes, respectively, for capturing stereo images. According to one embodiment, the electronic device may select two cameras positioned left and right based on the inclination of the electronic device for capturing stereo images.

[0096] According to one embodiment, when the sensed inclination of the electronic device falls within a first range, the electronic device may be determined to correspond to a "landscape mode." According to one embodiment, the landscape mode may be a state in which the hinge structure is arranged in a landscape direction (or horizontal direction) that includes a direction parallel to the x-axis in the coordinate system illustrated in FIG. 2A and within a set angle with respect to the direction of the x-axis. According to one embodiment, when the sensed inclination of the electronic device falls within the first range, the first direction in which the plurality of rear cameras included in the fourth surface of the electronic device are arranged may be a landscape direction (or horizontal direction) that includes a direction parallel to the x-axis and within a set angle with respect to the direction of the x-axis.

[0097] According to one embodiment, the electronic device may select two cameras (e.g., an ultra-wide-angle camera and a wide-angle camera) from among a plurality of rear cameras arranged in a first direction parallel to the hinge structure when the electronic device is in landscape mode.

[0098] According to one embodiment, if the tilt of the sensed electronic device falls within a second range different from the first range, the electronic device may be determined to correspond to a “portrait mode.” According to one embodiment, the portrait mode may be a state in which the hinge structure is arranged in a portrait direction (or vertical direction) that includes a direction orthogonal to the x-axis in the coordinate system illustrated in FIG. 2A and deviates from the direction of the x-axis by a set angle.

[0099] According to one embodiment, when the inclination of the sensed electronic device is included in the second range, the first direction in which the plurality of rear cameras included in the fourth face of the electronic device are arranged includes a direction orthogonal to the x-axis, and may be a portrait direction (or vertical direction) that is within a set angle from the direction of the x-axis.

[0100] In one embodiment, the electronic device may, when the electronic device is in portrait mode, select two cameras from among a plurality of rear cameras and a front cover camera, wherein the two cameras are arranged in a first direction parallel to the hinge structure and a second direction different from the first direction. In one embodiment, the second direction may include directions within a set angle including a direction orthogonal to the first direction.

[0101] According to one embodiment, the electronic device may select two cameras from among a plurality of rear cameras and a front cover camera by further considering a folding state of the electronic device when the electronic device is in portrait mode. For example, the electronic device may select two cameras from among the plurality of rear cameras and a front cover camera by further considering a folding angle sensed by at least one sensor for sensing a folding state of the electronic device (e.g., the sensor module (176) of FIG. 1). For example, the at least one sensor for sensing a folding state of the electronic device may include an acceleration sensor and / or a Hall sensor.

[0102] According to one embodiment, the electronic device may select one of the plurality of rear cameras and the front cover camera based on whether the sensed tilt of the electronic device falls within a second range and whether the folding angle sensed by the second sensor falls within a first range. For example, when the electronic device is in portrait mode and the folding angle falls within a first range in which the plurality of rear cameras and the front cover camera can capture the same subject, the electronic device may select one of the plurality of rear cameras and the front cover camera.

[0103] According to one embodiment, the electronic device can determine that the first housing and the second housing are in an unfolded state when the folding angle is within a first range.

[0104] In one embodiment, when the electronic device includes a plurality of first rear cameras arranged in a single row, and the electronic device is in portrait mode and in an unfolded state, one of the plurality of first rear cameras (e.g., an ultra-wide-angle camera) and a front cover camera may be selected as described above. In one embodiment, the selected one of the rear camera and the front cover camera may be arranged in a second direction.

[0105] In this way, the electronic device can capture stereo images using one rear camera and one front cover camera even in portrait mode, and can obtain stereo images with improved depth perception depending on the distance between the rear camera and the front cover camera.

[0106] In one embodiment, the electronic device comprises a plurality of first rear cameras arranged in two rows and at least one second rear camera, and when the electronic device is in a portrait mode and in an unfolded state, the electronic device may select one of the plurality of rear cameras and a front cover camera, or select one of the plurality of first rear cameras in the first row (e.g., a wide-angle camera) and one of the at least one second rear camera in the second row (e.g., a telephoto camera).

[0107] In one embodiment, the selected one rear camera and the front cover camera, or the selected first row rear camera and the selected second row rear camera may be arranged in a second direction.

[0108] For example, if the depth perception of the stereo image is more important than the quality (e.g., picture quality) of the stereo image, for a function that uses stereo images, or for a performance of the stereo image that the user desires, the electronic device may select one of the multiple rear cameras and the front cover camera.

[0109] In one embodiment, when the quality (e.g., picture quality) of the stereo image is more important than the depth perception of the stereo image, the electronic device may select one of the plurality of first rear cameras in the first row and one of the at least one second rear camera in the second row included in the plurality of rear cameras.

[0110] In this way, the electronic device can capture a stereo image using one of the plurality of first rear cameras in the first row and one of the at least one second rear camera in the second row even in portrait mode, and can obtain a stereo image with improved quality depending on the performance of the rear cameras.

[0111] According to one embodiment, the electronic device may provide an indicator for notifying that a stereo image cannot be generated based on a sensed tilt of the electronic device being within a second range and a folding angle being outside a first range. For example, if the electronic device is in portrait mode and the folding angle is outside a first range in which multiple rear cameras and a front cover camera can capture the same subject, the electronic device may provide an indicator for notifying that a stereo image cannot be generated. According to one embodiment, if the folding angle is outside the first range, the electronic device may determine that the first housing and the second housing are in a semi-folding state in which the first housing and the second housing are partially folded or in a folding state in which the first housing and the second housing are folded.

[0112] In one embodiment, when the electronic device includes only a plurality of first rear cameras arranged in a single row, and the electronic device is in portrait mode and in a semi-folding or folding state, the electronic device may provide an indicator indicating that it is unable to generate a stereo image, as described above.

[0113] In one embodiment, when the electronic device includes a plurality of first rear cameras arranged in two rows and at least one second rear camera, when the electronic device is in portrait mode and in a semi-folded or folded state, the electronic device may select one of the plurality of first rear cameras in the first row (e.g., a wide-angle camera) and one of the at least one second rear camera in the second row (e.g., a telephoto camera). In one embodiment, the selected first row rear camera and the selected second row rear camera may be arranged in a second direction.

[0114] In this way, even in a semi-folding or folding state in portrait mode, a stereo image can be captured using one of the plurality of first rear cameras in the first row and one of at least one second rear camera in the second row, and a stereo image with improved quality can be obtained depending on the performance of the rear cameras.

[0115] According to one embodiment, the operation of selecting two cameras for capturing stereo images while further considering the folding state of the electronic device will be described in more detail below with reference to FIG. 5.

[0116] According to one embodiment, when multiple rear cameras are arranged in two rows, the operation of selecting two cameras for shooting stereo images will be described in more detail with reference to FIG. 6 below.

[0118] According to one embodiment, the electronic device may perform image processing to align the acquired left-eye and right-eye images. For example, correction may be performed so that corresponding points included in the left-eye and right-eye images each have the same y-coordinate.

[0119] According to one embodiment, the electronic device may store the corrected stereo image in a memory (e.g., memory (130) of FIG. 1).

[0120] According to one embodiment, the electronic device may transmit the corrected stereo image to an external electronic device (e.g., a head mounted display (HMD) device) via a communication module (e.g., the communication module (190) of FIG. 1).

[0121] FIG. 5 is a flowchart illustrating an operation of selecting two cameras for generating a stereo image based on the tilt and folding status of an electronic device according to one embodiment of the present disclosure.

[0122] Referring to FIG. 5, according to one embodiment, in operation 501, an electronic device (e.g., the electronic device (101) of FIG. 1, the processor (120) of FIG. 1, the electronic device (101) of FIG. 2A) may receive a user input for capturing a stereo image. For example, the electronic device may receive a user input (e.g., a touch input or a voice input) for capturing a stereo image through a running screen of a camera application.

For example, the at least one sensor may include at least one of a gyro sensor or an acceleration sensor.

[0125] According to one embodiment, if the inclination of the electronic device is within the first range (operation 502 - yes), in operation 503, two rear cameras (393-1, 393-2) among the plurality of first rear cameras may be selected.

[0126] In one embodiment, if the tilt of the electronic device falls within the first range, the electronic device may be determined to correspond to “landscape mode”.

[0127] According to one embodiment, the electronic device may select two rear cameras (393-1, 393-2) from among a plurality of first rear cameras arranged in a first direction parallel to the hinge structure when the electronic device is in landscape mode. For example, rear camera A (393-1) may be an ultra-wide-angle camera, and rear camera B (393-2) may be a wide-angle camera.

In one embodiment, if the tilt of the electronic device is outside the first range, the electronic device may be determined to correspond to a “portrait mode.”

[0131] According to one embodiment, the electronic device may sense a folding angle through at least one sensor (e.g., the sensor module (176) of FIG. 1) for sensing a folding state of the electronic device when the electronic device is in portrait mode. For example, the at least one sensor for sensing a folding state of the electronic device may include an acceleration sensor and / or a Hall sensor.

[0133] For example, a first range may include a range greater than 90 degrees and less than 180 degrees, and a second range may include a range greater than or equal to 0 degrees and less than or equal to 90 degrees.

[0134] According to one embodiment, the electronic device may select one rear camera A (393-1) and a front cover camera (383) among the plurality of first rear cameras in operation 506 when the folding angle is within the first range (operation 505 - yes).

[0139] According to one embodiment, the electronic device may provide at least one of a sound, a vibration, or a screen display as an indicator to indicate that stereo imaging is not possible.

[0140] In one embodiment, when the electronic device is in portrait mode and the folding angle is outside the first range in which the plurality of rear cameras and the front cover camera can capture the same subject, the electronic device can be determined to correspond to a semi-folding state in which the first housing and the second housing are partially folded or a folding state in which the first housing and the second housing are folded.

[0141] In one embodiment, when the electronic device is in portrait mode and in a semi-folded or folded state, the electronic device may display a message indicating that stereo photography is not possible on the camera application's launch screen, or provide an audible and / or vibration notification. In one embodiment, the message indicating that stereo photography is not possible may include a message prompting the user to change the electronic device to landscape mode or to an unfolded state.

For example, the rear camera A (393-1) in the first row may be an ultra-wide-angle camera, and the rear camera B (393-2) in the first row may be a wide-angle camera.

[0148] In one embodiment, in operation 604, the electronic device may acquire stereo images through two selected rear cameras.

[0151] In one embodiment, when shooting a person in stereo, shooting a short-form video, or when the user wants a stereo image with a tall aspect ratio or a stereo image with a high sense of depth, the electronic device may determine that the sense of depth in the stereo image is more important than the quality of the stereo image.

[0152] In one embodiment, when shooting a landscape or a vlog with stereo images, or when the user wants a stereo image with a wide aspect ratio or a high quality stereo image, the electronic device may determine that the quality of the stereo image is more important than the depth of the stereo image.

A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0196] An embodiment of the present document may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101) or an electronic device (301)). For example, a processor (e.g., a processor (520)) of the machine (e.g., an electronic device (301)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

The computer program product may be traded between sellers and buyers as a product. The computer program product may be distributed in the form of a device-readable storage medium (e.g., compact disc read-only memory (CD-ROM)) or may be available through an application store (e.g., Play Store). TM ) or directly between two user devices (e.g., smart phones), online distribution (e.g., downloading or uploading). In the case of online distribution, at least a portion of the computer program product may be at least temporarily stored or temporarily created in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0198] According to one embodiment, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components. According to one embodiment, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to one embodiment, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
