[0030] In connection with the description of the drawings, the same or similar reference numerals may be used for identical or similar components.

[0031] Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that various modifications, equivalents, and / or alternatives of the embodiments of the present invention are included.

[0032] FIG. 1 is a block diagram of an operation for shooting and displaying multiple videos according to one embodiment of the present disclosure.

[0033] Referring to FIG. 1, in one embodiment of the present disclosure, an electronic device (e.g., electronic device (10) of FIG. 2) may be configured to perform an operation of capturing a video (110) and / or an operation of displaying a video (130).

[0034] The act of capturing a video (110) may include an act of capturing multiple videos simultaneously using an electronic device. For example, the electronic device may include multiple cameras (e.g., multiple cameras (270) of FIG. 2). The electronic device may capture multiple videos substantially simultaneously using at least two of the multiple cameras. For example, the electronic device may capture multiple videos using a camera combination (e.g., a combination set by a user) including two or more of the multiple cameras. A method of capturing multiple videos using an electronic device may be described below with reference to FIGS. 3 to 7.

[0035] The operation (130) of displaying a video may include an operation of switching and displaying multiple videos that were simultaneously captured according to a specific trigger. In one example, the multiple videos of operation 130 may be videos captured by the electronic device according to operation 110 or videos captured by another electronic device. For example, the specific trigger may include an input to the electronic device (e.g., a user input) and / or a preset timeline (e.g., a preset time and / or time interval). In one example, the operation (130) of displaying a video may include an operation of displaying an affordance for displaying a second video on the display of the electronic device on which the first video is being displayed. For example, the first video and the second video may each correspond to videos captured simultaneously by the electronic device using multiple cameras of the same subject. For example, the first video and the second video may each correspond to videos captured simultaneously by the electronic device using multiple cameras of the same subject at different magnifications.

[0036] In one example, the operation (130) of displaying a video may include an operation of displaying a second video, based on an input for an affordance, overlaying the first video being displayed, or replacing the first video being displayed. In one example, the operation of displaying a second video overlaying the first video being displayed may be expressed as an operation of switching videos. For example, the operation (130) of displaying a video may include an operation of displaying a second video captured by a different camera simultaneously with the first video being captured, overlaying the first video, or switching from the first video, when a touch input for the affordance is acquired while the first video is being displayed. The operation (130) of displaying a video may be described below with reference to FIGS. 8 to 14 .

[0037] With respect to FIG. 1, it has been described that video recording (e.g., operation 110) and video display (e.g., operation 130) are performed by a single electronic device; however, embodiments of the present disclosure are not limited thereto. An electronic device according to an embodiment of the present disclosure (e.g., electronic device (10) of FIG. 2) may be configured to perform at least one of video recording, video editing, or video display.

[0038] FIG. 2 is a block diagram showing the configuration of an electronic device according to one embodiment of the present disclosure.

[0039] Referring to FIG. 2, an electronic device (10) according to an embodiment of the present disclosure may include at least one processor (e.g., processor (220)), memory (230), display (260), or at least one of a plurality of cameras (270). For example, the electronic device (10) may include any electronic device such as a smart phone, a laptop, a desktop, a television, a smart pad, a tablet PC, a wearable device, a closed-circuit television (CCTV) camera equipment, a connected car, and / or a portable terminal. The types of the electronic device (10) described above are merely examples, and the embodiments of the present disclosure are not limited thereto. The electronic device (10) may include any electronic device configured to capture a video (e.g., operation 110 of FIG. 1) and / or play a video (e.g., operation 130 of FIG. 1).

[0040] In one embodiment of the present disclosure, at least one processor (e.g., processor (220)) may be connected to memory (230), display (260), and multiple cameras (270). For example, at least one processor may be electrically and / or communicatively connected to components of the electronic device (10). For example, at least one processor may be wired or wirelessly connected to components of the electronic device (10). At least one processor may be composed of a single chip or multiple chips (e.g., chipset). For example, at least one processor may include at least one processing circuitry such as a central processing unit (CPU), an application processor (AP), a microprocessor unit (MPU), a communication processor (CP), a system on chip (SoC), a neural processing unit (NPU), a graphic processing unit (GPU), or an integrated circuit (IC).

[0041] In one embodiment of the present disclosure, at least one processor may perform operations necessary for the operation of the electronic device (10). In one example, the operations of the electronic device (10) may be performed by at least one processor individually or collectively executing instructions. Some of the operations of the electronic device (10) may be performed by a first processor executing instructions, and at least some of the remaining operations may be performed by a processor different from the first processor executing instructions. At least one processor may control components of the electronic device (10). For example, the operations of the electronic device (10) described in the present disclosure may be referred to as being performed by at least one processor. For example, the operations of the electronic device (10) may be performed by at least one processor executing instructions stored in the memory (230). At least one processor may be referred to by the processor (2010) of FIG. 20.

[0042] In one embodiment of the present disclosure, the memory (230) may include built-in memory or external memory. For example, the built-in memory may include at least one of a volatile memory (e.g., dynamic random access memory (DRAM), static random access memory (SRAM), or synchronous DRAM (SDRAM)), a non-volatile memory (e.g., programmable read-only memory (PROM), one time PROM (OTPROM), erasable PROM (EPROM), electrically erasable and PROM (EEPROM), mask ROM, flash ROM, flash memory, a hard drive, or a solid state drive (SSD). The external memory may include at least one of a flash drive (e.g., compact flash), secure digital (SD), micro-SD, mini-SD, extreme digital (xD), multi-media card (MMC), or a memory stick. The memory (230) may be referenced by the memory (2020) of FIG. 20.

[0043] In one embodiment of the present disclosure, the memory (230) may store instructions that can be executed by at least one processor (e.g., the processor (220)). The memory (230) may store at least one data related to the operation of the electronic device (10) or a command related to the functional operation of components of the electronic device (10). For example, the memory (230) may store at least one application that is preloaded upon manufacturing the electronic device (10) or downloaded as a third-party app from an online market (e.g., an app store). For example, the at least one application may include a voice recognition application that supports the operation of a voice recognition service.

[0044] In one embodiment of the present disclosure, the display (260) may be implemented as a touchscreen display including a display panel, a cover glass, and a touch panel (or touch sensor). The display panel may receive a driving signal corresponding to image information at a specified frame rate and output a related screen based on the driving signal. The cover glass may be positioned above the display panel to transmit light according to the screen output of the display panel. The display (260) may be referenced by the display (2040) of FIG. 20.

[0045] In one example, the display (260) may include multiple displays. For example, the display (260) may include a left-eye display and a right-eye display. The display (260) may include a front display and a back display. The display (260) may include at least one of a see-through display, a flexible display, a rollable display, a foldable display, and / or a rigid display. For example, the display (260) may be viewed through the front side or the back side of the foldable electronic device.

[0046] In one embodiment of the present disclosure, the electronic device (10) may provide at least one preview of a video being captured using the display (260). In one example, the electronic device (10) may provide an image captured using a first camera among the plurality of cameras (270) as a main preview through the display (260), and an image captured using a second camera among the plurality of cameras (270) as a mini preview. For example, the main preview may correspond to an image displayed as a preview on the display (260) during video capture. For example, the mini preview may correspond to an image displayed as a preview in at least a portion of the main preview. In one example, the mini preview may be displayed overlapping the main preview or in a separate area from the main preview. For example, examples of the main preview and the mini preview may be referenced by FIGS. 4 to 6B. In one example, the first camera and the second camera may have different camera characteristics. For example, the camera characteristics may include at least one of the focal length, magnification, field of view of the lens, or characteristics of the image sensor included in the camera (e.g., resolution, aspect ratio, sensitivity, dynamic range, and / or frame rate, etc.). The electronic device (10) may provide an affordance to switch between displaying the main preview and the mini preview through the display (260). The first camera and the second camera may correspond to, for example, front cameras (e.g., the first front camera (271-1) and the second front camera (271-2)) or rear cameras (e.g., the first rear camera (272-1) and the second rear camera (272-2)).

[0047] In one embodiment of the present disclosure, the electronic device (10) may provide different aspect ratios for the mini preview and the main preview. In one example, the aspect ratio may correspond to the aspect ratio of an image (e.g., a still image or a video) (e.g., 4:3, 16:9), but in the embodiment of the present disclosure, the aspect ratio may correspond to the width-to-height ratio of the image, but is not limited thereto. For example, in the present disclosure, the aspect ratio of the preview may correspond to the width-to-height ratio at which the video is displayed on the display (260). For example, when the electronic device (10) is in a vertical orientation (e.g., portrait mode), the horizontal length of the video may correspond to the length of the video on an axis extending between the left and right sides of the electronic device (10), and the vertical length of the video may correspond to the length of the video on an axis extending between the upper and lower sides of the electronic device (10). In one example, when the electronic device (10) is in a portrait orientation, the aspect ratio of the preview may correspond to the ratio of the short axis (e.g., the horizontal axis of the electronic device (10)) to the long axis (e.g., the vertical axis of the electronic device (10)) of the electronic device (10). For example, when the electronic device (10) is in a landscape orientation (e.g., landscape mode), the horizontal length of the video may correspond to the length of the video along the axis extending between the left and right sides of the electronic device (10), and the vertical length of the video may correspond to the length of the video along the axis extending between the top and bottom sides of the electronic device (10). For example, when the electronic device (10) is in a landscape orientation (e.g., landscape mode), the aspect ratio of the preview may correspond to the ratio of the long axis to the short axis of the electronic device (10). The aspect ratio of the video (or preview) may be set based on the orientation in which the electronic device (10) displays the image.

[0048] In one example of the present disclosure, an aspect ratio corresponding to a horizontal direction (e.g., landscape mode) of the electronic device (10) may correspond to a ratio of a long axis to a short axis of the electronic device (10), and an aspect ratio corresponding to a vertical direction (e.g., portrait mode) of the electronic device (10) may correspond to a ratio of a short axis to a long axis of the electronic device (10).

[0049] In one embodiment of the present disclosure, the electronic device (10) may provide an affordance for changing the aspect ratio of a mini-preview via the display (260). The display (260) may provide an affordance for displaying a video different from the currently displayed video. The display (260) may provide an affordance indicating that there is a different video captured simultaneously with the currently displayed video.

[0050] The term "affordance" as used herein may include a user-interactive graphical user interface (GUI) object that may be optionally displayed on a display screen of an electronic device (e.g., electronic device (10)). For example, an affordance may include at least one of an image (e.g., an icon), a button, or text (e.g., a hyperlink).

[0051] In one embodiment of the present disclosure, a plurality of cameras (270) may be arranged on the front or rear of the electronic device (10). For example, the plurality of cameras (270) may include a front camera (e.g., a first front camera (271-1) and / or a second front camera (271-2)) positioned on the front of the electronic device (10) and / or a rear camera (e.g., a first rear camera (272-1) and / or a second rear camera (272-2)) positioned on the rear of the electronic device (10). For example, the front of the electronic device (10) may correspond to an area on the surface of the electronic device (10) where a main display (e.g., a relatively large display among the displays of the electronic device (10)) is positioned (e.g., an area where the main display is visible). For example, the rear of the electronic device (10) may correspond to an area on the surface of the electronic device (10) located opposite the main display. The front camera and / or the rear camera may each include at least one camera (e.g., a dual camera implemented with two cameras). The front camera and / or the rear camera may include an auxiliary light source (e.g., a flash) (not shown) that provides the amount of light required for shooting. For example, the plurality of cameras (270) may include the image sensor (2050) of FIG. 20.

[0052] In the present disclosure, the plurality of cameras (270) are illustrated as including, but not limited to, two front cameras (271-1, 271-2) and two rear cameras (272-1, 272-2). For example, the plurality of cameras (270) may include two or more front cameras and / or two or more rear cameras. For example, the plurality of cameras (270) may not include at least one of the illustrated cameras.

[0053] In one embodiment of the present disclosure, the plurality of cameras (270) may include cameras having different characteristics and / or specifications. For example, the camera characteristics may include at least one of a focal length, a magnification, a field of view (FOV) of a lens included in each camera, or characteristics of an image sensor included in the camera (e.g., resolution, aspect ratio of an image, sensitivity, dynamic range, and / or frame rate, etc.). In one example, the electronic device (10) may simultaneously capture the same subject using a first camera and a second camera having different characteristics among the plurality of cameras (270). The plurality of cameras (270) may include, for example, a wide-angle camera including a wide-angle lens, a standard-angle camera including a standard-angle lens, and / or a telephoto camera including a telephoto lens. The standard-angle lens may correspond to a lens having a narrower angle of view than a wide-angle lens and a wider angle of view than a telephoto lens. For example, the electronic device (10) can acquire a wide-angle image using a first camera having a relatively wide angle of view, and can acquire a telephoto image using a second camera having a relatively narrow angle of view. For example, each of the plurality of cameras (270) can include at least one of a standard lens, a wide-angle lens, a telephoto lens, a fish-eye lens, a micro lens, or a zoom lens. For example, at least some of the plurality of cameras (270) can have different focal lengths.

[0054] In the examples of the present disclosure, the first camera and the second camera may correspond to cameras positioned on the same side when capturing a video. For example, the electronic device (10) may capture multiple videos by simultaneously capturing the same subject using the first camera and the second camera positioned on the same side. For example, since the positions of the cameras in electronic devices (10) having various form factors may change when capturing a video, the first camera and the second camera may correspond to cameras positioned on the same side (e.g., front or rear) when capturing a video.

[0055] In one example, the electronic device (10) can acquire a video having the same or similar characteristics by adjusting the focal length and / or magnification of the first camera and / or the second camera. For example, the electronic device (10) can control the first camera so that the first camera has the same or similar angle of view (e.g., the same or similar magnification) as the second camera by adjusting the magnification of the first camera (e.g., optical zoom-in and / or digital zoom-in). After controlling the first camera so that the first camera has similar characteristics to the second camera, the electronic device (10) can capture a video using the first camera.

[0056] In one embodiment of the present disclosure, the electronic device (10) may obtain an input for displaying a second video. In one example, the electronic device (10) may, while displaying a first video captured by a first camera, display an affordance for displaying a second video captured by a second camera by overlaying the displayed first video. In one example, the electronic device (10) may display the second video on the display (260) based on the input for the affordance for displaying the second video. For example, the affordance for displaying the second video may indicate an area corresponding to the second video in the first video. For example, the affordance for displaying the second video may include a visual guide indicating at least a portion of the first video corresponding to the second video. For example, specific examples of the affordance for displaying the second video may be described later with reference to FIGS. 9A and / or 9B . When the electronic device (10) obtains an input for displaying a second video while displaying a first video, the electronic device can display the second video by overlapping it on the first video or by switching from the first video.

[0057] In one embodiment of the present disclosure, the electronic device (10) can display a first video and a second video in time synchronization when at least one instruction stored in the memory (230) is executed by at least one processor. In one example, the electronic device (10) can display the first video and the second video in time synchronization when simultaneously captured first and second videos are interchangeably displayed. The electronic device (10) can time synchronize the first video and the second video using capture time and / or playback time information of the first and second videos. For example, the electronic device (10) can time synchronize the first video and the second video using time information included in metadata of the first and second videos.

[0058] In one embodiment of the present disclosure, the first aspect ratio of the first video and the second aspect ratio of the second video may be different. For example, the first aspect ratio may correspond to an aspect ratio corresponding to a horizontal orientation (e.g., landscape mode) of the electronic device (10), and the second aspect ratio may correspond to an aspect ratio corresponding to a vertical orientation (e.g., portrait mode) of the electronic device (10). For example, the horizontal length of the first video may be longer than the vertical length. For example, the vertical length of the second video may be longer than the horizontal length. For example, the width-to-height ratio of the first video displayed by the horizontal electronic device (10) may be similar to or the same as the height-to-width ratio of the second video displayed by the vertical electronic device (10).

[0059] In one example, the second video may be comprised of images corresponding to at least a portion of the images captured by the second camera. For example, a second video comprised of images corresponding to a portion of the images captured by the second camera may be further described with reference to FIG. 7.

[0060] In one embodiment of the present disclosure, an input for an affordance for displaying a second video while displaying a first video may include a user's touch input for the affordance. For example, when the electronic device (10) receives a user's touch input for the affordance displayed over the first video being displayed, the electronic device (10) may display the second video by overlaying it over the first video or by switching from the first video.

[0061] In one embodiment of the present disclosure, the electronic device (10) may further include an orientation sensor (e.g., a gyro sensor, a micro-electro mechanical system (MEMS), and / or an acceleration sensor) that detects orientation. In one example, the electronic device (10) may switch from a first video and display a second video based on detecting a change in the orientation of the electronic device (10) through the orientation sensor when at least one instruction stored in the memory (230) is executed by at least one processor. For example, if a user rotates the electronic device (10) within a specified angular range (e.g., 90 degrees) while displaying the first video, the electronic device (10) may switch from the first video to the second video and display the second video.

[0062] In one embodiment of the present disclosure, the electronic device (10) may further include a sensor (e.g., a hinge sensor, an acceleration sensor, a magnetic sensor, and / or a gyro sensor) for detecting a folding angle according to unfolding or folding of the electronic device (10) and / or a hinge for folding or unfolding the electronic device (10). In one example, the electronic device (10) may switch from a first video and display a second video based on detecting folding or unfolding of the electronic device (10) through the sensor for detecting the folding angle when at least one instruction stored in the memory (230) is executed by at least one processor. For example, when the electronic device (10) detects a folding angle of the display (260) greater than a certain angle while displaying the first video, the electronic device (10) may switch to the second video and display the second video.

[0063] FIG. 3 is a flowchart of an operation of an electronic device capturing a plurality of videos according to one embodiment of the present disclosure.

[0064] Referring to FIGS. 2 and 3, in operation 310, the electronic device (10) may set a camera combination. In one example, the electronic device (10) may display a camera setting affordance (e.g., affordance (411) of FIG. 4) for setting a camera combination on the display (260). The electronic device (10) may set a camera combination by determining a combination of at least two cameras (270). For example, the electronic device (10) may select two cameras (e.g., a first camera and a second camera) to capture two videos simultaneously. Operation 310 may be further described later with reference to FIG. 4.

[0065] In operation 320, the electronic device (10) may determine a main preview and a mini preview. For example, the electronic device (10) may provide a video captured by a camera as a preview that can be viewed in advance. In one example, the electronic device (10) may determine a camera to be provided as a main preview and a camera to be provided as a mini preview based on the camera combination set in operation 310. For example, when simultaneously capturing a video using a first camera and a second camera, the electronic device (10) may display a video captured by the first camera as a main preview on the display (260) and display a video captured by the second camera as a mini preview on the display (260). The main preview and the mini preview may be displayed simultaneously on at least a portion of the display (260). The mini preview may be displayed on at least a portion of the main preview or may be displayed outside the display area of ​​the main preview. The area displaying the main preview may be larger than the area displaying the mini preview. In one example, the main preview may be referred to as the first preview and the mini preview may be referred to as the second preview.

[0066] In one example, the electronic device (10) may display a preview switching affordance (e.g., affordance (511) of FIG. 5) on the display (260) to switch between cameras corresponding to the main preview and the mini preview, respectively. The electronic device (10) may switch between cameras corresponding to the main preview and the mini preview, respectively, based on an input to the preview switching affordance. For example, when images captured using the first camera and the second camera are displayed as a main preview and a mini preview, respectively, on the display, when the electronic device (10) detects a user's touch input to the preview switching affordance (e.g., affordance (511) of FIG. 5), the electronic device may switch the image captured using the first camera to a mini preview and display it, and switch the image captured using the second camera to a main preview and display it. Operation 320 may be further described later with reference to FIG. 5.

[0067] In operation 330, the electronic device (10) according to one embodiment of the present disclosure may determine an aspect ratio of the main preview and an aspect ratio of the mini preview. For example, the aspect ratio of the main preview may be related to the aspect ratio of the electronic device (10). For example, when a user holds the electronic device (10) in a vertical direction and takes a picture (e.g., when the electronic device (10) operates in a portrait mode), the main preview of the electronic device (10) may be provided with an aspect ratio corresponding to the vertical direction (e.g., an aspect ratio in which the vertical length of the main preview is longer than the horizontal length). For example, when a user rotates the electronic device (10) in a horizontal direction (e.g., a landscape mode), the main preview of the electronic device (10) may be provided with an aspect ratio corresponding to the horizontal direction (e.g., an aspect ratio in which the horizontal length of the main preview is longer than the vertical length).

[0068] In one example, the electronic device (10) may set the aspect ratio of the main preview to be the same as or different from the aspect ratio of the mini preview. For example, the electronic device (10) may display an aspect ratio changing affordance (e.g., affordance (611) of FIG. 6A or 6B) that can change the aspect ratio of the mini preview on the mini preview. When the electronic device (10) detects an input for changing the aspect ratio displayed on the mini preview (e.g., an input for the aspect ratio changing affordance), the electronic device (10) may change the aspect ratio of the mini preview. Operation 330 may be further described with reference to FIG. 6A and / or FIG. 6B .

[0069] FIG. 4 is an example diagram of a UI (User Interface) for setting a combination of cameras to be photographed simultaneously by an electronic device according to one embodiment of the present disclosure.

[0070] Referring to FIGS. 3 and 4, the first UI (410) may include a preview (e.g., a main preview (401) and / or a mini preview (402)) or a camera setting affordance (411) provided when the electronic device (10) according to one embodiment of the present disclosure captures a video. In one example, the electronic device (10) may provide an image (e.g., a video or a still image) captured using a camera combination set through the first UI (410) as the main preview (401) and the mini preview (402). For example, the electronic device (10) may display an image captured by a camera including a wide-angle lens as the main preview (401) and may display an image captured by a camera including a telephoto lens as the mini preview (402) through the first UI (410).

[0071] In one embodiment of the present disclosure, the second UI (420) may include previews (e.g., a first preview (403), a second preview (404), a third preview (405), and a fourth preview (406)) of images captured by each of the plurality of cameras (e.g., the plurality of cameras (270) of FIG. 2) included in the electronic device (10). For example, the second UI (420) may include at least one of a first preview (403) of an image captured using a first camera including an ultra-wide-angle lens, a preview (404) of an image captured using a second camera including a wide-angle lens, a preview (405) of an image captured using a third camera including a first telephoto lens, or a preview (406) of an image captured using a fourth camera including a second telephoto lens. In one example, the electronic device (10) may display a second UI (420) based on an input to a camera setting affordance (411). Based on the input to the previews being displayed in the second UI (420) (e.g., a first preview (403), a second preview (404), a third preview (405), and a fourth preview (406)), the electronic device (10) may determine which previews will be displayed as the main preview (401) and the mini preview (402). For example, when sequential inputs for the first preview (403) and the second preview (404) on the second UI (420) are detected, the electronic device (10) can first display the first preview (403) for which the input was detected as the main preview (401) through the first UI (410), and subsequently display the second preview (404) for which the input was detected as the mini preview (402).

[0072] Although the first UI (410) of FIG. 4 is illustrated as including only two previews (e.g., a main preview (401) and a mini preview (402)), the electronic device (10) may provide more than two previews simultaneously. Furthermore, although the second UI (420) is illustrated as including previews of images captured using four different cameras (e.g., a first preview (403), a second preview (404), a third preview (405), and a fourth preview (406)), the electronic device (10) may include four or more cameras to provide four or more previews. The first UI (410) and the second UI (420) described above with respect to FIG. 4 are examples, and embodiments of the present disclosure are not limited thereto. For example, the first UI (410) and / or the second UI (420) may not include some of the configurations illustrated in FIG. 4, or may further include configurations not illustrated in FIG. 4. The above-described previews (e.g., main preview (401), mini preview (402), first preview (403), second preview (404), third preview (405), and fourth preview (406)) may also be referred to as preview windows or preview display areas.

[0073] FIG. 5 is an example diagram of a UI in which an electronic device switches between displaying a main preview and a mini preview according to one embodiment of the present disclosure.

[0074] In one embodiment of the present disclosure, referring to FIG. 5, the first UI (510) may include previews (e.g., main preview (501) and mini preview (502)) of images (e.g., video or still images) captured using a first camera (not shown) and a second camera (not shown) of the electronic device (10). For example, referring to the first UI (510), the electronic device (10) may display a preview of an image captured by a first camera including a telephoto lens as a main preview (501), and may display a preview of an image captured by a second camera including a wide-angle lens as a mini preview (502). The electronic device (10) may display a preview switching affordance (511) that can switch the display of the main preview (501) and the mini preview (502) between each other. For example, the electronic device (10) can display a preview transition affordance (511) on a mini preview (502).

[0075] In one embodiment of the present disclosure, the electronic device (10) may display a second UI (520) based on an input (e.g., a touch input) identified for a preview switching affordance (511) while the first UI (510) is being displayed. On the second UI (520), the main preview (501) and the mini preview (502) displayed on the first UI (510) may be switched and displayed with each other. For example, referring to the second UI (520), the electronic device (10) may display a preview of an image captured by a second camera including a wide-angle lens as a main preview (503), and may display a preview of an image captured by a first camera including a telephoto lens as a mini preview (504).

[0076] In the example of FIG. 5, a preview switching affordance (511) is described, but embodiments of the present disclosure are not limited thereto. For example, when an input for a mini preview (502 or 504) is received, the electronic device (10) can switch between displaying the mini preview and the main preview.

[0077] The first UI (510) and second UI (520) described above with reference to FIG. 5 are merely examples, and embodiments of the present disclosure are not limited thereto. For example, the first UI (510) and / or the second UI (520) may not include some of the configurations illustrated in FIG. 5, or may further include configurations not illustrated in FIG. 5.

[0078] FIG. 6A is an example of a UI for changing the aspect ratio of a mini preview in a landscape electronic device according to one embodiment of the present disclosure.

[0079] In one embodiment of the present disclosure, referring to FIGS. 3 and 6A, the first UI (610) may include previews (e.g., a main preview (601) and a first mini preview (602)) of images (e.g., still images or videos) captured using the first camera and the second camera of the electronic device (10). For example, referring to the first UI (620), the previews (e.g., the first preview and / or the second preview) of images captured using the first camera and the second camera may have an aspect ratio corresponding to the horizontal direction of the electronic device (10). Referring to the first UI (610), the electronic device (10) may display a first preview of an image captured by the first camera including a telephoto lens as the main preview (601), and may display a second preview of an image captured by the second camera including a wide-angle lens as the first mini preview (602). The electronic device (10) can display an aspect ratio change affordance (611) that can change the aspect ratio of the first mini preview (602). For example, the electronic device (10) can display the aspect ratio change affordance (611) on the first mini preview (602).

[0080] In one embodiment of the present disclosure, the electronic device (10) may display a second UI (620) based on an input (e.g., a touch input) identified for an aspect ratio change affordance (611) during display of the first UI (610). In one example, the second UI (620) may include a second mini-preview (603) having an aspect ratio different from that of the first mini-preview (602). For example, the second mini-preview (603) may have an aspect ratio corresponding to a vertical direction of the electronic device (10). For example, the electronic device (10) may display the second mini-preview (603) using the same image as the image provided through the first mini-preview (602). The first mini-preview (602) and the second mini-preview (603) may be captured by the same camera, and the second mini-preview (603) may be an image generated by cropping a portion of the captured image. For example, the second UI (620) may include a mini-preview (603) captured by a second camera including a wide-angle lens and having an aspect ratio corresponding to the vertical direction of the electronic device (10).

[0081] FIG. 6b is an example of a UI for changing the aspect ratio of a mini preview in a vertical electronic device according to one embodiment of the present disclosure.

[0082] In one embodiment of the present disclosure, referring to FIGS. 3 and 6b, the first UI (630) may include previews (e.g., a main preview (604) and a first mini preview (605)) of images captured using the first camera and the second camera of the electronic device (10). For example, referring to the first UI (630), the previews of images captured using the first camera and the second camera may have an aspect ratio corresponding to the vertical direction of the electronic device (10). For example, referring to the first UI (630), the electronic device (10) may display a preview of an image captured by the first camera including a telephoto lens as the main preview (604), and may display a preview of an image captured by the second camera including a wide-angle lens as the first mini preview (605). The electronic device (10) can display an aspect ratio change affordance (611) that can change the aspect ratio of the first mini preview (605). For example, the electronic device (10) can display the aspect ratio change affordance (611) on the first mini preview (605).

[0083] In one embodiment of the present disclosure, the electronic device (10) may display a second UI (640) based on an input (e.g., a touch input) identified for an aspect ratio change affordance (611). In one example, the second UI (620) may include a second mini-preview (606) having an aspect ratio different from that of the first mini-preview (605). For example, the second mini-preview (606) may have an aspect ratio corresponding to a horizontal direction of the electronic device (10). For example, the electronic device (10) may display an image identical to an image provided through the first mini-preview (605) as the second mini-preview (606). The first mini-preview (602) and the second mini-preview (603) may be captured by the same camera, and the second mini-preview (603) may be an image generated by cropping a portion of the captured image. For example, the second UI (640) may include a mini preview (606) captured by a second camera including a wide-angle lens and having an aspect ratio corresponding to the horizontal orientation of the electronic device (10).

[0084] The first UI (610, 630) and the second UI (620, 640) described above with respect to FIGS. 6A and 6B are merely examples, and embodiments of the present disclosure are not limited thereto. For example, the first UI (610, 630) and / or the second UI (620, 640) may not include some of the configurations illustrated in FIGS. 6A and / or 6B, or may further include configurations not illustrated in FIGS. 6A and / or 6B.

[0085] FIG. 7 is an exemplary diagram illustrating a method for an electronic device to capture videos having different aspect ratios, according to one embodiment of the present disclosure.

[0086] Referring to FIG. 7, in one embodiment of the present disclosure, an electronic device (e.g., the electronic device (10) of FIG. 2) may determine an aspect ratio (e.g., a width-to-height ratio) of a video being captured based on an input for changing the aspect ratio of the video being captured. For example, as described above with respect to FIGS. 6A and 6B, the electronic device (10) may determine an aspect ratio of a mini-preview (e.g., a first mini-preview (602) and a second mini-preview (603) of FIG. 6A, and a first mini-preview (605) and a second mini-preview (606) of FIG. 6B) based on an input for a user's aspect ratio changing affordance (e.g., an aspect ratio changing affordance (611) of FIG. 6). Although not shown in FIGS. 6A and 6B , the electronic device (10) may also determine the aspect ratio of the main preview (e.g., the main preview (601), main preview (604) of FIG. 6 ) based on an input for determining the aspect ratio, similar to changing the aspect ratio of the mini preview. For example, the electronic device (10) may change the aspect ratio of the main preview based on an input for an aspect ratio changing affordance (not shown) of the main preview.

[0087] In one example, the electronic device (10) may determine the aspect ratio (e.g., width-to-height ratio) of the video being captured based on the rotation of the terminal. For example, when a user uses the terminal in a vertical orientation (e.g., portrait mode), the electronic device (10) may determine the aspect ratio of the video being captured as an aspect ratio (e.g., 9:16, 3:4) corresponding to the vertical orientation of the electronic device (10). For example, when a user uses the terminal in a horizontal orientation (e.g., landscape mode), the electronic device (10) may determine the aspect ratio of the video being captured as an aspect ratio (e.g., 16:9, 4:3) corresponding to the horizontal orientation of the electronic device (10).

[0088] In one embodiment of the present disclosure, the electronic device (10) can capture multiple videos with different aspect ratios using multiple cameras (e.g., multiple cameras (270) of FIG. 2). In one example, the electronic device (10) can simultaneously capture the same subject with different aspect ratios using two or more cameras positioned on the same side (e.g., front or rear) among the multiple cameras (270). For example, the electronic device (10) can simultaneously capture a first video with a first aspect ratio and a second video with a second aspect ratio using a first camera (not shown) and a second camera (not shown). In one example, the electronic device (10) can set the aspect ratios of the two videos to be different by zooming in and / or cropping the acquired images.

[0089] For example, the first aspect ratio may have an aspect ratio corresponding to the current orientation mode of the terminal, and the second aspect ratio may have an aspect ratio corresponding to a direction different from the terminal orientation. When the electronic device (10) is currently in landscape mode, the first aspect ratio may have an aspect ratio (e.g., 16:9) corresponding to the landscape orientation of the electronic device (10), and the second aspect ratio may have an aspect ratio (e.g., 9:16) corresponding to the portrait orientation (portrait mode) of the electronic device (10). For example, when the electronic device (10) is currently in portrait mode, the first aspect ratio may have an aspect ratio (e.g., 9:16) corresponding to the portrait orientation of the electronic device (10), and the second aspect ratio may have an aspect ratio (e.g., 16:9) corresponding to the landscape orientation (landscape mode) of the electronic device (10).

[0090] A first example (710) may illustrate a method for a landscape-oriented electronic device (10) to acquire a video (e.g., a first video (721)) using a first camera (not shown) including a wide-angle lens. In one example, a first area (711) of an image sensor of the electronic device (10) may correspond to an area in which the image sensor of the first camera captures a subject when the electronic device (10) is in a landscape orientation. A first aspect ratio of the first video (721) captured by the first camera may correspond to an aspect ratio (e.g., a width-to-height ratio) of the first area (711). For example, the first aspect ratio may have an aspect ratio corresponding to an orientation of the electronic device (10) (e.g., a landscape orientation (landscape mode), a portrait orientation (portrait mode)). For example, the first aspect ratio of the first video (721) may have an aspect ratio corresponding to a landscape orientation (landscape mode) of the electronic device (10).

[0091] A second example (720) may illustrate a method for an electronic device (10) in a landscape orientation to capture a video (e.g., a video (722)) having a second aspect ratio different from the first aspect ratio, using a second camera (not shown) including a telephoto lens. In one example, a second area (712) of an image sensor of the electronic device (10) may correspond to an area where the image sensor of the second camera captures a subject when the electronic device (10) is in a landscape orientation. The electronic device (10) may capture a video (722) having the second aspect ratio even when the electronic device (10) is in a landscape orientation, using a third area (713), which is a part of the second area (712). In one example, the electronic device (10) may capture a video using the second area (712), and may crop an area corresponding to the third area (713) from the captured video and store it in the electronic device (10) or display it on a display.

[0092] The second aspect ratio of the second video (722) captured by the second camera may correspond to the aspect ratio (e.g., width-to-height ratio) of the third area (713). For example, the aspect ratio of the third area (713) may have a different aspect ratio from the aspect ratio corresponding to the terminal orientation of the electronic device (10). For example, in the second example drawing (720), the orientation of the electronic device (10) is a horizontal direction (landscape mode), but the second aspect ratio of the second video (722) may have an aspect ratio corresponding to the vertical direction (e.g., portrait mode) of the electronic device (10). The electronic device (10) may capture a video of the second aspect ratio using only a portion of the image sensor of the second camera or using only a portion of the image acquired by the second camera. For example, the electronic device (10) may capture a subject entering the third area (713) using only a portion of the image sensor of the second camera. For example, the third region (713) may correspond to some region having an aspect ratio (e.g., width-to-height ratio) of 9:16 or 3:4 at the center of the sensor of the second camera.

[0093] In the present disclosure, the aspect ratio refers to the aspect ratio of length to width (e.g., 4:3, 16:9), but in the embodiments of the present disclosure, the aspect ratio may correspond to the ratio of width to height, but is not limited thereto. For example, the aspect ratio of a video may correspond to the ratio of width to height of a video displayed on the display of an electronic device (10).

[0094] FIG. 8 is a flowchart of a method for an electronic device to display videos according to one embodiment of the present disclosure.

[0095] Referring to FIG. 8, in operation 810, an electronic device (e.g., the electronic device (10) of FIG. 2) may display a first video. In one example, the electronic device (10) may display a first video captured by a first camera among a plurality of cameras (e.g., the plurality of cameras (270) of FIG. 2). For example, the first video may correspond to a video captured using a first camera included in a camera combination set by a user.

[0096] In operation 820, the electronic device (10) may display an affordance for displaying a second video. In one example, the electronic device (10) may display the affordance on the first video being displayed. For example, the second video may correspond to a video captured using a second camera that is included in the camera combination set by the user and is different from the first camera. For example, the second video may correspond to a video captured simultaneously with the first video.

[0097] In operation 830, the electronic device (10) may display a second video based on an input for displaying the second video. The electronic device (10) may obtain an input for displaying the second video. For example, the input may include a touch input for an affordance displayed on the first video. For example, the input may include a touch input (e.g., a double tap, a pinch zoom gesture, and / or a floating button tap) to the electronic device (10). Based on the identification of the input associated with displaying the second video, the electronic device (10) may switch the first video being displayed to the second video and display it, or display the second video by at least partially overlapping the first video being displayed.

[0098] In one embodiment of the present disclosure, the electronic device (10) can display the second video by time-synchronizing the first video and the second video. In one example, the electronic device (10) can display the second video from a playback time of the second video that matches the playback time of the time point at which the first video is switched by time-synchronizing the first and second videos that were shot simultaneously. For example, if the first video and the second video are 1-minute videos, and the electronic device (10) switches to the second video 30 seconds after displaying the first video, the second video can be displayed from the 30-second time point.

[0099] FIG. 9A is an exemplary diagram showing an electronic device according to one embodiment of the present disclosure switching between displaying a first video and a second video.

[0100] Referring to FIGS. 8 and 9A, in one embodiment of the present disclosure, an electronic device (e.g., the electronic device (10) of FIG. 2) may display a first video (910) and a second video (920) by switching between them. In one example, the first video (910) and the second video (920) may correspond to videos captured simultaneously using a first camera and a second camera included in a camera combination set by a user (e.g., the camera combination set in operation 310 of FIG. 3). For example, the first camera may correspond to a camera including a wide-angle lens, and the second camera may correspond to a camera including a telephoto lens. For example, the first camera and the second camera may be cameras positioned on the same side (e.g., the front or the back) of the electronic device (10).

[0101] The electronic device (10) may display a first video transition affordance (911) that can switch to a second video (920) while displaying a first video (910). For example, the electronic device (10) may display the first video transition affordance (910) over the first video (910). In one example, the first video transition affordance (911) may correspond to an affordance that points to an area that includes substantially the same portion as a subject included in the second video (920) over the first video (910) being displayed. In one example, the first video transition affordance (911) may include an affordance that points to substantially the same area as the second video (920) over the first video (910) being displayed.

[0102] The electronic device (10) can switch between and display multiple simultaneously captured videos based on an input for a video switching affordance (e.g., a first video switching affordance (911), a second video switching affordance (921)). In one example, when a first video (910) is being displayed on the display of the electronic device (10), the electronic device (10) can switch from the first video (910) to the second video (920) and display it based on an input for the first video switching affordance (911). For example, the input can include a touch input to the electronic device (10) (e.g., a double tap, a pinch zoom gesture, and / or a floating button tap). For example, if the electronic device (10) identifies a double tap input within a corresponding area of ​​the first video switching affordance (911), it can switch the first video (910) to the second video (920) and display it.

[0103] The electronic device (10) may display a second video switching affordance (921) that can switch to display the first video (910) while displaying the second video (920). In one example, the second video switching affordance (921) may be associated with an input for switching from the second video (920) to the first video (910). For example, in order to switch and display the first video (910) captured using the first camera including a wide-angle lens from the second video (920) captured using the second camera including a telephoto lens, the user may use a pinching motion with two fingers. As illustrated in FIG. 9A, the electronic device (10) may display a second video switching affordance (921) indicating that switching to display the first video (910) captured using the first camera on the second video (920) is possible.

[0104] FIG. 9B is an exemplary diagram showing an affordance for an electronic device to switch the display of a first video to the display of a second video according to one embodiment of the present disclosure.

[0105] Referring to FIGS. 8 and 9B, in one embodiment of the present disclosure, an electronic device (e.g., the electronic device (10) of FIG. 2) may display a plurality of videos (e.g., a first video (930) and a second video (not shown)) captured in a horizontal direction. For example, the first video (930) and the second video (not shown) may correspond to videos captured simultaneously by a first camera including a wide-angle lens and a second camera including a telephoto lens among a plurality of cameras (e.g., a plurality of cameras (270) of FIG. 2) of the electronic device (10), respectively. For example, the first camera and the second camera may be cameras positioned on the same side (e.g., the front or the rear) of the electronic device (10).

[0106] The electronic device (10) may display a video transition affordance (931) to switch the display of the first video (930) to a second video during the display of the first video (930). For example, the electronic device (10) may display the video transition affordance (931) over the first video (930). For example, the second video may correspond to a video captured with a different aspect ratio from the first video (930). For example, the aspect ratio of the second video may have an aspect ratio corresponding to the vertical direction of the electronic device (10). In one example, the video transition affordance (931) may include an affordance indicating an area of ​​the second video. For example, the video transition affordance (931) may correspond to an affordance indicating an area that includes substantially the same portion as a subject included in the second video. For example, the video transition affordance (931) may include an affordance that points to a portion corresponding to substantially the same area as the second video.

[0107] The electronic device (10) can switch between and display multiple simultaneously captured videos based on an input to the video switching affordance (931). In one example, when a first video (930) is being displayed on the display of the electronic device (10), the electronic device (10) can switch from the first video (930) to a second video (not shown) based on an input to the video switching affordance (931) and display the video. For example, the input is as described above with reference to FIG. 9A.

[0108] The form of the video transition affordances (911, 921, 931) described with reference to FIGS. 9A and 9B is exemplary, and embodiments of the present disclosure are not limited thereto. For example, the video transition affordances may have a form similar to the mini-preview described above with reference to FIGS. 6A and 6B.

[0109] FIG. 10 is an exemplary diagram illustrating a step of switching a first video to a second video and displaying it while the first video is being displayed by an electronic device according to one embodiment of the present disclosure.

[0110] Referring to FIG. 10, an electronic device according to an embodiment of the present disclosure (e.g., the electronic device (10) of FIG. 2) may display a first video on a display, and then switch the first video to a second video. For example, the first video may correspond to a video captured by a first camera including a wide-angle lens, and the second video may correspond to a video captured by a second camera including a telephoto lens.

[0111] In one embodiment of the present disclosure, the electronic device (10) can synchronize time information (e.g., shooting time information or playback time information) included in a first video and a second video, respectively. In one example, the first video and the second video may have different frame rates. The electronic device (10) can match the frame rates of the first video and the second video by performing frame interpolation on the video having a lower frame rate. In one example, the electronic device (10) can match the frame rates of the first video and the second video by excluding at least some of the frames of the video having a higher frame rate.

[0112] Referring to FIG. 10, frame images (or still images) shown in the order of playback time while the first video or the second video is displayed (e.g., the first image (1001), the second image (1002), the third image (1003), the third image (1004), the fifth image (1005), the sixth image (1006), the seventh image (1007), the eighth image (1008), the ninth image (1009)) may correspond to frames at specific points in time included in the video during the display of the video. For example, the first image (1001), the second image (1002), and the third image (1003) may be frame images included in the first video, the fourth image (1004), the fifth image (1005), and the sixth image (1006) may be frame images included in the second video that is displayed by switching from the first video, and the seventh image (1007), the eighth image (1008), and the ninth image (1009) may be frame images included in the first video that is displayed by switching from the second video.

[0113] In one embodiment of the present disclosure, the electronic device (10) may, in response to an input for switching a first video being displayed on a display to a second video, display frame images of a second video instead of frame images of the first video. In order to switch from the first video to the second video, the electronic device (10) may provide a visual effect for video switching between the first video and the second video.

[0114] For example, the electronic device (10) may adjust the magnification of a first video and display it, and then switch to a second video and display it. In one example, when switching from a first video taken with a first camera including a wide-angle lens to a second video taken with a second camera including a telephoto lens and displaying it, the electronic device (10) may gradually (or stepwise) enlarge the magnification of the first video being displayed on a display (e.g., the display (260) of FIG. 2) within a certain period of time so that the size of a portion corresponding to a subject included in the first video becomes the same as (or similar to) the size of a portion corresponding to the subject included in the second video, and when the size of a portion corresponding to the subject included in the enlarged first video becomes substantially the same as the size of a portion corresponding to the subject included in the second video, the electronic device may switch to and display the second video. For example, referring to FIG. 10, the electronic device (10) can display a second image (1002) and a third image (1003) by gradually enlarging the frame images of the first video being displayed in frame order (or chronological order). The illustrated second image (1002) and third image (1003) are some of the continuous frame images displayed in the process of gradually enlarging the first video. The first graph (1010), the second graph (1020), and the third graph (1030) are graphs that represent the relative display sizes of portions corresponding to subjects included in the first video and the second video in chronological order. The electronic device (10) can switch to the second video and display the first video by gradually enlarging it based on a determination that the size of the portion corresponding to the subject included in the third image (1003) is substantially the same as the size of the portion corresponding to the subject included in the fourth image (1004) of the second video. Referring to FIG. 10, the fourth image (1004), the fifth image (1005), and the sixth image (1006) may be frame images displayed without adjusting the magnification of the second video.A method for determining whether the size of a portion corresponding to a subject included in a third image (1003) is substantially the same as the size of a portion corresponding to a subject included in a fourth image (1004) of a second video may include a method using an example of a magnification value in Table 1 described below.

[0115] In one embodiment of the present disclosure, when switching from a first video to a second video and then switching back to the first video and displaying it, the electronic device (10) may use an enlarged first video. In one example, in order to smoothly switch between multiple videos, the electronic device (10) may, in response to an input for switching the second video to the first video while displaying the second video, enlarge a frame of the first video so that the size of a portion corresponding to a subject included in the first video matches the size of a portion corresponding to a subject included in the second video at the time corresponding to the input, and then display the first video. For example, referring to FIG. 10 , when switching back to the first video while displaying the second video, the electronic device (10) may display a seventh image (1007) corresponding to a frame with an enlarged magnification of the first video. From the time the enlarged seventh image (1007) is displayed, the first video displayed may be gradually reduced and displayed at its original magnification.

[0116] Referring to FIG. 10 , in one embodiment of the present disclosure, the electronic device (10) may identify a command (e.g., user input) for switching between displaying a first video and displaying a second video at time t1 or t6. For example, the electronic device (10) may digitally zoom in on (or zoom in on) the first video being displayed at time t1. For example, the electronic device (10) may digitally zoom in on (or zoom out on) the first video to be displayed at time t6. A method for the electronic device (10) to zoom in or out on the first video so that the positions and sizes of subjects included in the frame images before and after the time point at which the first video and the second video are switched and displayed are as close as possible to each other may be described in detail later in FIG. 11 .

[0117] In one embodiment of the present disclosure, during a process of switching the first video to a second video while displaying the first video, the electronic device (10) may match the position and size of a subject included in frame images included during a certain period of time before and after the time at which the first video and the second video are switched. For example, the electronic device (10) may determine a method for matching the position and size of the subject during the switching display based on a combination of a camera corresponding to the first video and a camera corresponding to the second video. In one example, the electronic device (10) may determine a rate of change in the size of the first video based on lens characteristics (e.g., magnification) of each camera that captured the first video and the second video. For example, if a first video is shot at a standard magnification of 1x (1x) with a first camera including a wide-angle lens, and a second video is shot at a standard magnification of 3x (3x) with a second camera including a telephoto lens, when switching the display from the first video to the second video, the electronic device (10) can digitally zoom in (e.g., gradually zoom in) the size of the first video by 300% (or 3x) so that the size of a portion corresponding to a subject included in the first video can substantially match the size of a portion corresponding to the subject included in the second video. For example, if a third video is shot at a magnification of 0.6x (0.6x) compared to the reference magnification with a third camera including an ultra-wide-angle lens, and a fourth video is shot at a magnification of 10x (10x) compared to the reference magnification with a fourth camera including a telephoto lens, when switching the display from the third video to the fourth video, the electronic device (10) can digitally zoom in on the size of the third video by 1500% (or 15x) so that the size of a portion corresponding to a subject included in the third video can be substantially matched to the size of a portion corresponding to the subject included in the fourth video.

[0118] [Table 1] may indicate, in one embodiment of the present disclosure, when switching the display from a first video to a second video, a magnification value used to enlarge or reduce the first video for a natural transition display, depending on the lens and magnification at the time of shooting included in each of the first camera that shot the first video and the second camera that shot the second video.

[0119] 1st camera 2nd camera Magnification value 3x telephoto 10x telephoto 345% 1x wide angle 10x telephoto 1000% 0.6x ultra wide angle 10x telephoto 1500% 1x wide angle 3x telephoto 300% 0.6x ultra wide angle 3x telephoto 450% 0.6x ultra wide angle 1x wide angle 120%

[0120] FIG. 11 is a flowchart of a method for an electronic device to move the display position of at least one video based on each matching center point to display two videos by switching between them, according to one embodiment of the present disclosure.

[0121] Referring to FIG. 11, in operation 1110, the electronic device (10) may determine target frames. For example, when the electronic device (10) wants to switch to a second video while displaying a first video (e.g., when an input for switching to the second video is identified), the electronic device (10) may determine target frames (or frame images) of each video corresponding to the switching point. For example, the electronic device (10) may determine a specified number of frames of the first video before the switching point (e.g., frames within a specified time before the switching point) and a specified number of frames of the second video after the switching point (e.g., frames within a specified time after the switching point) as target frames.

[0122] For example, in relation to a first video and a second video shot simultaneously, each of which is one minute long, if the first video is to be switched to the second video and displayed at a point 30 seconds from the start of playback of the first video, the frames included in the first video at the 30-second point and the frames included in the second video can be determined as target frames. In this case, the input for switching the first video to the second video and displaying it can be identified before the 30-second point.

[0123] In operation 1120, the electronic device (10) according to an embodiment of the present disclosure may extract feature points from each frame. In one example, the electronic device (10) may extract feature points from each of the target frames determined in operation 1110 (e.g., a first frame image included in a first video and a second frame image included in a second video) using an image processing technique. For example, the electronic device (10) may extract feature points using information such as a gradient histogram, brightness, color, direction, and size of pixels included in the frame. In one example, the electronic device (10) may extract feature points based on artificial intelligence machine learning or deep learning. The electronic device (10) may extract feature points from the frame images using a trained artificial neural network.

[0124] In operation 1130, the electronic device (10) according to an embodiment of the present disclosure may match or compare feature points extracted from two frame images. For example, matching may include, through operation 1120, an operation of determining whether feature points extracted from two frame images match or whether the similarity is greater than a threshold. For example, the electronic device (10) may determine the similarity between feature points extracted from two frames based on the distribution of feature points extracted from the two frame images (e.g., the number and relative positions of feature points).

[0125] In operation 1140, the electronic device (10) according to an embodiment of the present disclosure may identify a matching center point. If it is determined through operation 1130 that the feature points extracted from the two frame images match or have a similarity greater than a threshold value, the extracted feature points may be said to correspond to portions corresponding to the same subject included in the two frame images, respectively, and the electronic device (10) may determine the center point of the feature points for each frame image as a matching center point. For example, the electronic device (10) may identify a feature point pattern (e.g., distribution) in the first frame and the second frame having a similarity greater than a threshold value based on a comparison of feature points between the first frame and the second frame. The electronic device (10) may identify a first feature point pattern extracted from the first frame and a second feature point pattern extracted from the second frame, the similarities of which are greater than or equal to the threshold value. The electronic device (10) may identify a first center point of the first feature point pattern and a second center point of the second feature point pattern.

[0126] In operation 1150, the electronic device (10) according to one embodiment of the present disclosure may move the display position of the second video based on the matching center point. In one example, the electronic device (10) may determine the display position of the second frame image so that the matching center point of the second frame image included in the second video matches the position of the matching center point of the first frame image included in the first video for a natural transition in the process of switching from the first video to the second video based on the determined matching center point of each frame image. Specifically, the electronic device (10) may determine the display position of the second frame image by adding a first vector from a center point corresponding to the exact center of the first video to a center point of feature points of the first frame image included in the first video, and a second vector from a center point of feature points of the second frame image included in the second video to a center point corresponding to the exact center of the second video.

[0127] In one embodiment of the present disclosure, the electronic device (10) can perform a natural transition display between two videos by using the method of adjusting the display size of the video described above in FIG. 10 and the method of determining the display position of the video described above in FIG. 11. The effects for the transition display of the video described above with respect to FIGS. 10 and 11 are merely examples, and the embodiments of the present disclosure are not limited thereto. For example, the electronic device (10) can perform the transition of the video by using effects for resolve, fade out and fade-in, or any screen transition.

[0128] FIG. 12 is an example diagram showing an electronic device displaying videos with different aspect ratios by switching between them, according to one embodiment of the present disclosure.

[0129] Referring to FIG. 12 , according to one embodiment, the electronic device (10) can switch videos based on a change in orientation of the electronic device (10). In the examples described above, input for affordances has been described as input for switching videos, but embodiments of the present disclosure are not limited thereto. For example, the input for switching videos may include a change in orientation of the electronic device (10).

[0130] The first video (1210) and the second video (1220) may correspond to videos captured simultaneously by a first camera and a second camera different from the first camera, respectively. In one example, the first video (1210) may correspond to a video captured by a first camera including a wide-angle lens, and the second video (1220) may correspond to a video captured by a second camera including a telephoto lens. The aspect ratio of the first video (1210) and the aspect ratio of the second video (1220) may be different. For example, the aspect ratio of the first video (1210) may have an aspect ratio corresponding to a horizontal direction (landscape mode) of the electronic device (10), and the second video (1220) may have an aspect ratio corresponding to a vertical direction (portrait mode) of the electronic device (10).

[0131] In one embodiment of the present disclosure, the electronic device (10) can capture videos having different aspect ratios through the first camera and the second camera, as described above with reference to FIGS. 6A and 6B . In one example, the first video (1210) may correspond to a video displayed by the electronic device (10) in a landscape orientation in a main preview (e.g., the main preview (601) of FIG. 6A ), and the second video (1220) may correspond to a video displayed by the electronic device (10) in a landscape orientation in a mini preview (e.g., the second mini preview (603) of FIG. 6A ) that has a different aspect ratio from the video displayed by the electronic device (10) in the main preview.

[0132] In one embodiment of the present disclosure, the electronic device (10) may switch between displaying a first video (1210) and a second video (1220) based on a user input for changing the orientation of the electronic device (10) to a horizontal or vertical direction or a rotation of the electronic device. For example, if a user input for changing to a vertical direction (e.g., rotation of the terminal) is identified while the electronic device (10) in a horizontal direction is displaying the first video (1210), the electronic device (10) may switch the display of the first video (1210) to the display of the second video (1220). Conversely, if a user input for changing to a horizontal direction is identified while the electronic device (10) in a vertical direction is displaying the second video (1220), the electronic device (10) may switch the display of the second video (1220) to the display of the first video (1210).

[0133] FIGS. 13A to 13C are exemplary diagrams showing an electronic device displaying videos having different aspect ratios by switching between them, according to one embodiment of the present disclosure.

[0134] Referring to FIG. 13A, the first video (1310) and the second video (1320) may correspond to videos captured simultaneously by a first camera and a second camera different from the first camera, respectively. In one example, the first video (1310) may correspond to a video captured by a first camera including a telephoto lens, and the second video (1320) may correspond to a video captured by a second camera including a wide-angle lens. The aspect ratio of the first video (1310) and the aspect ratio of the second video (1320) may be different. For example, the aspect ratio of the first video (1310) may have an aspect ratio corresponding to a vertical direction of the electronic device (10), and the second video (1320) may have an aspect ratio corresponding to a horizontal direction of the electronic device (10). For example, since the field of view of the first camera is smaller than that of the second camera, parts of the subject or background that are not included in the first video may be included in the second video.

[0135] In one embodiment of the present disclosure, the electronic device (10) can capture videos having different aspect ratios through the first camera and the second camera, as described above with reference to FIGS. 6A and 6B . In one example, the second video (1320) may correspond to the video displayed in the main preview of FIG. 6A by the landscape-oriented electronic device (10). The first video (1310) may have a different aspect ratio from the video displayed in the main preview (601) and may correspond to the video displayed in the mini preview (603) of FIG. 6A .

[0136] In one embodiment of the present disclosure, the electronic device (10) can switch and display multiple videos captured simultaneously with different aspect ratios based on a user input. For example, the user input can include at least one of a swipe, a double tap, a continuous touch input according to a specified pattern, a pinch zoom, or a touch input. In one example, the electronic device (10) can switch and display a first video (1310) and a second video (1320) based on the user input. For example, when the electronic device (10) in a landscape orientation is displaying a first video (1310) having an aspect ratio corresponding to a portrait orientation, if the user input is identified, the electronic device (10) can switch the display of the first video (1310) to the display of the second video (1320). Conversely, if the user input is identified while the electronic device (10) in landscape orientation is displaying the second video (1320), the electronic device (10) may switch the display of the second video (1320) to the display of the first video (1310).

[0137] Referring to FIG. 13B, the third video (1330) may correspond to the second video (1320) of FIG. 13A, and the fourth video (1340) may correspond to the first video (1310) of FIG. 13A. For example, the third video (1330) may correspond to a video captured by a second camera including a wide-angle lens, and the fourth video (1340) may correspond to a video captured by a first camera including a telephoto lens.

[0138] In one embodiment of the present disclosure, the electronic device (10) may display a third video (1330) and a fourth video (1340) by switching between them based on a user input. For example, the user input may include the user input described above with respect to FIG. 13A. In one example, when a vertical electronic device (10) is displaying a third video (1330) having an aspect ratio corresponding to a horizontal direction, if a user input is identified, the electronic device (10) may switch the third video (1330) to a fourth video (1340) and display it. Conversely, when a vertical electronic device (10) is displaying a fourth video (1340), if the user input is identified, the electronic device (10) may switch the fourth video (1340) to the third video (1330) and display it.

[0139] Referring to FIG. 13c, the fifth video (1350) may correspond to the second video (1320) of FIG. 13a or the third video (1330) of FIG. 13b, and the sixth video (1360) may correspond to the first video (1310) of FIG. 13a or the fourth video (1340) of FIG. 13b. For example, the fifth video (1350) may correspond to a video captured by a second camera including a wide-angle lens, and the sixth video (1360) may correspond to a video captured by a first camera including a telephoto lens.

[0140] In one embodiment of the present disclosure, the electronic device (10) may include a foldable electronic device. In one example, the electronic device (10) may display a fifth video (1350) and a sixth video (1360) by switching between them based on a user input. For example, the user input may include folding and / or unfolding the foldable electronic device.

[0141] In one example, the electronic device (10) may display a fifth video (1350) on a main display (e.g., a relatively large display among the displays of the electronic device (10)). The electronic device (10) may display a sixth video (1360) on a sub-display (e.g., a relatively small display among the displays of the electronic device (10)) based on a user input for folding the electronic device while displaying the fifth video (1350). The electronic device (10) may display the fifth video (1350) on the main display based on a user input for unfolding the electronic device (10) while displaying the sixth video (1350) on the sub-display.

[0142] As illustrated in FIG. 13C, the electronic device (10) in the unfolded state can display a fifth video (1350) having an aspect ratio corresponding to the horizontal direction. If a user input for switching to a folded state is identified while the electronic device (10) is displaying the fifth video (1350), the electronic device (10) can switch the fifth video (1350) to a sixth video (1360) and display it. Conversely, if a user input for switching the electronic device (10) to an unfolded state is identified while the electronic device (10) in the folded state is displaying the sixth video (1360), the electronic device (10) can switch the sixth video (1360) to the fifth video (1350) and display it.

[0143] FIG. 14 is an example diagram showing an electronic device displaying videos with different aspect ratios by switching between them, according to one embodiment of the present disclosure.

[0144] In one embodiment of the present disclosure, the electronic device (10) can capture multiple videos with different aspect ratios using multiple cameras (e.g., multiple cameras (270) of FIG. 2). In one example, the electronic device (10) can simultaneously capture the same subject with different aspect ratios using two or more cameras positioned on the same surface (e.g., front or rear) among the multiple cameras (270). For example, the electronic device (10) can simultaneously acquire a first video (1410) with a first aspect ratio and a second video (1420) with a second aspect ratio using a first camera (not shown) and a second camera (not shown). Referring to FIG. 14, during display of the second video (1420), the electronic device (10) can convert the second video (1420) into the first video (1410) and display it. The second video (1420) illustrated in FIG. 14 may correspond to a still image (or frame image) of the second video.

[0145] In one example, the first aspect ratio may have an aspect ratio corresponding to the current orientation of the terminal (e.g., horizontal or vertical), and the second aspect ratio may have an aspect ratio different from the first aspect ratio. For example, the first aspect ratio may have an aspect ratio corresponding to the horizontal orientation (landscape mode) of the electronic device (10) (e.g., 16:9, 4:3), and the second aspect ratio may have an aspect ratio corresponding to the vertical orientation (portrait mode) of the electronic device (10) (e.g., 9:16, 3:4).

[0146] In one embodiment of the present disclosure, referring to FIG. 14, an electronic device (e.g., the electronic device (10) of FIG. 2) may display videos having different aspect ratios by switching between them based on a user input. In one example, a first video (1410) and a second video (1420) may correspond to videos captured simultaneously by a first camera and a second camera different from the first camera, respectively. For example, the first video (1410) may correspond to a video captured by a first camera including a wide-angle lens, and the second video (1420) may correspond to a video captured by a second camera including a telephoto lens. For example, since the field of view of the first camera is larger than the field of view of the second camera, subject or background portions not included in the second video (1410) may be included in the first video (1420).

[0147] In one embodiment of the present disclosure, the electronic device (10) may, based on a user input, switch the second video (1420) to the first video (1410) while displaying the second video (1420). In one example, the first video (1410) may be stored in the electronic device (10) so as to match the second video (1420) (e.g., so that the feature points of each video correspond to each other), thereby enabling the electronic device (10) to perform a natural transition to the first video (1410) while displaying the second video (1420). For example, a portion of the first video (1410) corresponding to a substantially identical portion to a subject included in the second video (1420) may be matched with the second video (1420), and even if there is a different portion that is not included in the second video (1420), the portion of the first video (1410) may be replaced and displayed for that portion, thereby enabling a natural transition display between videos. In one example, the electronic device (10) can use information about a match between a first video (1410) and a second video (1420) (e.g., the playback time and / or position of the second video relative to the first video) to display a natural transition between the two videos.

[0148] In one example, the electronic device (10) may display left and right areas that are not included in the second video (1420) based on a user's gesture input, such as a drag or panning input. For example, the left and right areas that are not included in the second video (1420) may correspond to some of the areas included in the first video (1410). For example, the electronic device (10), while displaying the second video (1420), may display some areas of the first video (1410) that are not included in the second video (1420) based on identification of a panning motion corresponding to the user's left, right, up, and / or down directions. Through this function, the electronic device (10) may provide the user with an interactive expandability effect for short-form content provided on SNS.

[0149] FIGS. 15A to 15D are exemplary diagrams of an electronic device storing and playing edited object videos for each subject object included in the video, according to one embodiment of the present disclosure.

[0150] In one embodiment of the present disclosure, FIG. 15A illustrates a process in which an electronic device (10) displays a first video (1510). Referring to FIG. 15A, an electronic device (e.g., the electronic device (10) of FIG. 2) may acquire a plurality of videos (e.g., a first video (1510), a second video (1520), a second-first video (1501), a second-second video (1502), a second-third video (1503), a second-fourth video (1504), a second-fifth video (1505)). In one example, the first video (1510) and the second video (1520) may correspond to videos captured using a first camera (not shown) and a second camera (not shown) respectively, which are arranged on the same side (e.g., the front or the rear) among a plurality of cameras (e.g., a plurality of cameras (270) of FIG. 2) of the electronic device (10). For example, the first camera and the second camera may each be included in a camera combination set by the user (e.g., the camera combination set in operation 310 of FIG. 3). For example, the first camera may correspond to a camera including a wide-angle lens, and the second camera may correspond to a camera including a telephoto lens.

[0151] In one embodiment of the present disclosure, referring to FIG. 15A, the first video (1510) and the second video (1520) may correspond to videos captured by the electronic device (10) in which a plurality of people are talking. In addition to the first video (1510) corresponding to a wide-angle video and the second video (1520) corresponding to a telephoto video, the electronic device (10) may store at least one video among the second-first video (1501), the second-second video (1502), the second-third video (1503), the second-fourth video (1504), and the second-fifth video (1505). In one example, the electronic device (10) may use object (e.g., person) recognition technology to identify a subject (object) included in the first video (1510) and / or the second video (1520) and recognize the speaking object. The electronic device (10) can store speech object videos by cropping a portion of the entire video (e.g., first video (1510), second video (1520)) that includes the recognized speech object.

[0152] In one embodiment of the present disclosure, each of the 2-1 video (1501), the 2-2 video (1502), the 2-3 video (1503), the 2-4 video (1504), and the 2-5 video (1505) is a video of a speech object cropped using the object recognition technology described above, and may correspond to a video enlarged using a digital zoom-in method so that parts corresponding to each object are enlarged and displayed. In one example, the electronic device may acquire videos of each object (e.g., the 2-1 video (1501), the 2-2 video (1502), the 2-3 video (1503), the 2-4 video (1504), and the 2-5 video (1505)) by digitally zooming in on the 2nd video (1520) captured using a telephoto camera. The electronic device (10) can obtain clearer videos with less deterioration by obtaining videos of each object from the second video (1520), compared to obtaining videos of each object by digitally zooming in on the first video (1510) taken using a wide-angle camera.

[0153] In one embodiment of the present disclosure, during display of the first video (1510), the electronic device (10) may display at least one of the videos (2-1 video (1501), 2-2 video (1502), 2-3 video (1503), 2-4 video (1504), or 2-5 video (1505)) of an object (e.g., a person) included in the first video (1510) that speaks based on a user input, by at least partially overlapping the display of the first video (1510) or the second video (1520), or by filling the screen with only the videos of the objects that speak. In one example, by additionally acquiring videos of each object (e.g., 2-1 video (1501), 2-2 video (1502), 2-3 video (1503), 2-4 video (1504), 2-5 video (1505)), the electronic device (10) can switch to a video corresponding to the speaking object among the additionally stored videos for each object when a specific object speaks while displaying the first video (1510) or the second video (1520) and display the video. In this case, the method for naturally switching the videos is as described above with reference to FIGS. 10 and 11.

[0154] Referring to FIG. 15B, in one example, the electronic device (10) can display side by side on the display videos that enlarge two objects having a conversation among the objects included in the first video (1510) (e.g., first object enlarged video (1501-1), second object enlarged video (1504-1)). The electronic device (10) can obtain videos that enlarge two objects having a conversation (e.g., first object enlarged video (1501-1), second object enlarged video (1504-1)) from videos of each object (e.g., second-first video (1501), second-fourth video (1504)). For example, the electronic device (10) can zoom in on the 2-1 video (1501) to obtain a first object enlarged video (1501-1) including an enlarged first object, and can zoom in on the 2-4 video (1504) to obtain a second object enlarged video (1504-1) including an enlarged second object. The electronic device (10) can display the obtained first object enlarged video (1501-1) and second object enlarged videos side by side (e.g., left and right) on the display at the same size.

[0155] Referring to FIG. 15c, in one example, the electronic device (10) may, while displaying the first video (1510), switch to a video that enlarges the object that is speaking (e.g., a second object enlarged video (1504-1)). For example, while displaying the first video (1510), if a command (e.g., a user input) for displaying the object that is speaking is identified, the electronic device (10) may switch to a video that enlarges the object that is currently speaking (e.g., a second object enlarged video (1504-1)) and display the first video (1510). In one example, when the electronic device (10) displays a second object enlargement video (1504-1) with a different aspect ratio from the first video (1501) currently being displayed, the area of ​​the display (e.g., the display (260) of FIG. 2) other than the area where the second object enlargement video (1504-1) is displayed may be blurred. For example, when, during the display of a first video (1510) having an aspect ratio corresponding to a horizontal direction (e.g., landscape mode), the electronic device (10) switches to and displays a second object enlargement video (1504-1) having a different aspect ratio (e.g., an aspect ratio corresponding to a vertical direction (portrait mode) of the electronic device (10), the electronic device (10) may blur the left and right areas of the area where the second object enlargement video (1504-1) is displayed on the display.

[0156] Referring to FIG. 15D, in one example, the electronic device (10) may display a video (e.g., a second object enlarged video (1504-1)) that floats and enlarges the object that is speaking while displaying the first video (1510). For example, when a command (e.g., a user input) for displaying the speaking object in an enlarged manner is identified while displaying the first video (1510), the electronic device (10) may display a video (e.g., a second object enlarged video (1504-1)) that enlarges the object that is currently speaking by overlapping at least a portion of the first video (1510). For example, the electronic device (10) may display the second object enlarged video (1504-1) in a relatively smaller size than the first video (1510).

[0157] FIG. 15e is an example diagram of an electronic device editing the display of multiple videos according to one embodiment of the present disclosure.

[0158] Referring to FIGS. 15A to 15E , an electronic device (10) according to one embodiment of the present disclosure can edit the display of multiple videos using multiple videos. In one example, the electronic device (10) can edit the display of a main video among multiple videos so that at least one sub-video is displayed overlapping or in a switched manner over the main video.

[0159] In one example, the electronic device (10) may provide an editing UI for editing the display of multiple videos. On the editing UI, the tracks of each video may be displayed in time alignment. For example, the electronic device (10) may use matching information between the videos to display each video track in time alignment. Each video track may be displayed with a corresponding thumbnail image. Since each track is automatically time aligned, a user can easily edit the playback order and timing between each track.

[0160] For example, the electronic device (10) can play track 1 from time t0 to time t7 and display the first video (1510) included in track 1 as the main video. The electronic device (10) can play track 2, track 3 and / or track 4 at a specific section while displaying the first video (1510). For example, the electronic device (10) can play track 2 from time t1 to time t3 and display the 2-1 video (1501) included in track 2 by overlaying it on the first video (1510) or by switching it from the first video (1510). For example, the electronic device (10) can play track 3 from time t2 to time t4 and display the 2-2 video (1502) included in track 3 by overlaying it on the first video (1510) or by switching it from the first video (1510). For example, the electronic device (10) can play track 4 from time t5 to time t6, and display the 2-3 video (1503) included in track 4 by overlapping it on the 1st video (1510) or switching it from the 1st video (1510). The electronic device (10) can display multiple sub-videos side by side simultaneously by overlapping it on the main video or replacing it. For example, from time t2 to time t3, which is the section where track 2 and track 3 are played simultaneously, the electronic device (10) can display the 2-1 video (1501) and the 2-2 video (1502) by overlapping it on the 1st video (1510), or can display the 2-1 video (1501) and the 2-2 video (1503) side by side (e.g., displaying the two videos left and right as illustrated in FIG. 15b) by replacing the 1st video (1510).

[0161] In one embodiment of the present disclosure, the electronic device (10) can identify the speech time of each object included in the first video (1510) and determine the display time of the videos of each object (e.g., the 2-1 video (1501), the 2-2 video (1502), and the 2-3 video (1503)). For example, the electronic device (10) can play track 2 including the 2-1 video (1501) from t1 to t3 based on the identification that the speech section of the object included in the 2-1 video (1501) is from t1 to t3. For example, the electronic device (10) can play track 3 including the 2-2 video (1502) from t2 to t4 based on the identification that the speech section of the object included in the 2-2 video (1502) is from t2 to t4. For example, the electronic device (10) can play track 4 including the 2-3 video (1503) from t5 to t6 based on the identification that the utterance section of the object included in the 2-3 video (1503) is from t5 to t6.

[0162] In one embodiment of the present disclosure, when the electronic device (10) switches and displays a main video (e.g., a first video (1510)) to a sub-video (e.g., a second-first video (1501), a second-second video (1502), a second-third video (1503)), the electronic device (10) may gradually enlarge the magnification of the main video, and when the size of a portion corresponding to an object included in the enlarged main video is substantially the same as the size of a portion corresponding to an object included in the sub-video to be switched and displayed, the electronic device (10) may switch and display the sub-video. In one example, the electronic device (10) may determine the speed of gradually enlarging the main video according to the magnification value of the image after the switch. For example, the electronic device (10) may determine a first magnification speed when the size corresponding to an object included in the main video is enlarged six times to be greater than a second magnification speed when the size corresponding to an object included in the main video is enlarged three times. For example, the electronic device (10) may determine the first magnification speed to be twice the second magnification speed. The method for displaying a main video by naturally switching to a sub-video by an electronic device (10) may include a method for adjusting the display size of the video described above in FIG. 10 and a method for determining the display position of the video described above in FIG. 11.

[0163] FIG. 16 is an exemplary diagram of a method for an electronic device to capture and play a video having a specific effect using multiple cameras, according to one embodiment of the present disclosure.

[0164] Referring to FIG. 16, in one embodiment of the present disclosure, an electronic device (e.g., the electronic device (10) of FIG. 2) can capture a video by sequentially zooming out from a large magnification to a small magnification or zooming in from a small magnification to a large magnification using three or more cameras (e.g., the multiple cameras (270) of FIG. 2). In one example, the electronic device (10) can activate each of the multiple cameras (270) only for a necessary amount of time. For example, the electronic device (10) can capture a first video (1601) by activating a first camera including a telephoto lens with a maximum magnification of 10x from time t1 to time t3 and gradually and sequentially lowering the magnification (e.g., 10x, 9x, ...) from time t1 to time t3. Although not illustrated, the first video (1601) can be stored as a video in which a subject is gradually reduced in size. The electronic device (10) can activate a second camera including a 3x magnification telephoto lens from time t2 to time t5, and record a second video (1602) by gradually and sequentially lowering the magnification (e.g., 3x, 2x, …) from time t2 to time t5. Although not illustrated, the second video (1602) can be stored as a video in which the subject is gradually reduced. The electronic device (10) can activate a third camera including a 1x magnification wide-angle lens from time t4 to time t7, and record a third video (1603) by gradually and sequentially lowering the magnification (e.g., 1x, 0.8x, …) from time t4 to time t7. Although not illustrated, the third video (1603) can be stored as a video in which the subject is gradually reduced. The electronic device (10) can activate a fourth camera including an ultra-wide-angle lens with a magnification of 0.6 from time t6 to t8 to record a fourth video (1604) by gradually and sequentially lowering the magnification (e.g., 0.6x, 0.4x, …) from time t6 to t8.Although not illustrated, the fourth video (1604) can be stored as a video in which the subject is gradually reduced. When the first video (1601), the second video (1602), the third video (1603), and the fourth video (1604) are played in sequence, the user can experience the effect of watching a single video that is continuously (or sequentially) and gradually reduced from a magnification of 10x to a magnification of 0.4x or less. In order to minimize interruptions when playing each video in sequence, an overlapping time is provided between the activation times of each camera described, but the electronic device (10) can also film without the overlapping time.

[0165] FIG. 17 is an example diagram of storing information about the point in time at which a plurality of videos are switched and displayed by an electronic device according to one embodiment of the present disclosure.

[0166] Referring to FIG. 17, in one embodiment of the present disclosure, an electronic device (e.g., the electronic device (10) of FIG. 2) may display a first video (1710) and a second video (1720). In one example, the first video (1710) and the second video (1720) may correspond to videos captured using a first camera and a second camera included in a camera combination (e.g., the camera combination set in operation 310 of FIG. 3), respectively. For example, the first camera may correspond to a camera including a wide-angle lens, and the second camera may correspond to a camera including a telephoto lens. When the electronic device (10) displays videos (e.g., the first video (1710) and the second video (1720)), the electronic device (10) may display a time bar (e.g., the first time bar (1701) and the second time bar (1702)).

[0167] In one embodiment of the present disclosure, the electronic device (10) may switch the display of the first video (1710) to the second video (1720) while displaying the first video (1710), or switch the display of the second video (1720) to the first video (1710) while displaying the second video (1720). In one example, instead of an input for switching the display between videos, the electronic device (10) may store information about the switching points of the videos in advance. In one example, when playing the first video (1710) or the second video (1720), the electronic device (10) may use the information about the switching points stored in advance to automatically switch the display of the first video (1710) and the second video (172) and play them without the user input. For example, when the electronic device (10) displays the second video (1720) instead of the first video (1710) at timeline t0 during display of the first video (1710), then displays the first video (1710) again instead of the second video (1720) at timeline t1 during display of the second video (1720), and then switches back to the second video (1720) instead of the first video (1710) at timeline t2 during display of the first video (1710), as illustrated in FIG. 17, at least one affordance (e.g., a bar color between t0 and t1 is different from a bar color between t1 and t2) may be displayed on the time bar (1702) in relation to the transition time.

[0168] FIG. 18 is an example diagram showing an electronic device synthesizing and displaying two videos acquired using multiple cameras according to one embodiment of the present disclosure.

In one example, the plurality of videos may correspond to videos captured using a first camera and a second camera included in a camera combination set by a user (e.g., a camera combination set in operation 310 of FIG. 3). For example, the first camera may correspond to a camera including a wide-angle lens, and the second camera may correspond to a camera including a telephoto lens. For example, the first camera and the second camera may be cameras positioned on the same side (e.g., the front or the rear) of the electronic device (10).

[0170] Referring to FIG. 18, in one embodiment of the present disclosure, a first video (1810) may correspond to a video captured by an electronic device (10) using a first camera. In one example, it can be confirmed that a license plate of a car is not clearly identified in the first video (1810) captured only by a first camera including a wide-angle lens. A second video (1820) may correspond to a video obtained by synthesizing a video captured by an electronic device (10) using a first camera and a video captured by a second camera including a telephoto lens. For example, as illustrated in FIG. 18, it can be confirmed that a license plate of a car is clearly identified in the second video (1820). A method for synthesizing a video captured by a first camera and a video captured by a second camera is as described above with reference to FIGS. 10 and 11. For example, the electronic device (10) may perform natural synthesis by matching the sizes and positions of parts corresponding to subjects included in each video.

[0171] FIG. 19 is an exemplary diagram of a method for an electronic device to photograph an object with multiple cameras based on object recognition according to one embodiment of the present disclosure.

[0172] In one embodiment of the present disclosure, an electronic device (e.g., electronic device (10) of FIG. 2) can capture a plurality of videos using a plurality of cameras.

For example, the first camera may correspond to a camera including a wide-angle lens, and the second camera may correspond to a camera including a telephoto lens.

[0173] Referring to FIG. 19, in one embodiment of the present disclosure, when a specific condition is met during the process of shooting a first video (1910) with a first camera, the electronic device (10) can activate a second camera to shoot a second video (1920). For example, when a person object is not recognized, the electronic device (10) can shoot the first video (1910) using the first camera to obtain a video having a wide field of view, and when a person object is recognized, the electronic device (10) can capture a second video (1920) by zooming in on the person object using the second camera.

[0174] In one embodiment of the present disclosure, when there is a time zone in which a first camera and a second camera are simultaneously captured while displaying a first video (1910), the electronic device (10) may display a video transition affordance (e.g., the first video transition affordance (911) of FIG. 9A) over the first video (1910). Based on a user input for the video transition affordance, the electronic device (10) may switch the first video (1910) to a second video (1920) and display it.
