The camera (240) can provide the acquired image data to the processor (210) in real time through an interface (e.g., a mobile industry processor interface). The camera (240) can include at least some of the configurations and / or functions of the camera module (180) of FIG. 1.

[0060] According to one embodiment, the memory (220) may temporarily or permanently store various data, including volatile memory and non-volatile memory. The memory (220) may include at least some of the configuration and / or functions of the memory (130) of FIG. 1, and may store the program (140) of FIG. 1.

[0061] According to one embodiment, the memory (220) may store various instructions that may be performed by the processor (210). Such instructions may include control commands such as arithmetic and logical operations, data movement, and / or input / output that may be recognized by the processor (210).

[0062] According to one embodiment, the processor (210) may be configured as one or more processors capable of performing calculations or data processing related to control and / or communication of each component of the electronic device (200). The processor (210) may include at least some of the configurations and / or functions of the processor (120) of FIG. 1.

[0063] According to one embodiment, there is no limitation to the computational and data processing functions that the processor (210) can implement on the electronic device (200), but this document will describe various embodiments for providing a UI (user interface) that can store and / or share a video that reflects slow-down playback (or accelerated playback) when the video is slowed down (or accelerated) through a gallery application. The operations of the processor (210) described below can be performed by loading instructions stored in the memory (220).

[0064] In this document, the description that a processor (210) can perform a certain operation (or function, work, task) may be interpreted to mean substantially the same as that an instruction (or command, computer program) that causes an electronic device (200) (or processor (210)) to perform the corresponding operation is stored in a memory (220) (e.g., non-volatile memory, storage). In addition, the description that a processor (210) can perform a certain operation may be interpreted to mean substantially the same as that at least one processor (210) can perform the corresponding operation.

[0065] In one embodiment, the processor (210) can store and execute a gallery application (or another application utilizing image resources). For example, the gallery application can display images stored in memory (220) and support various functions such as copying / deleting / moving images, sharing with other devices, and image editing. The images provided by the gallery application can include images acquired using the camera (240) and / or images downloaded via a network. Various embodiments of this document can also be provided through applications other than the gallery application.

[0066] According to one embodiment, the processor (210) can play an image using the gallery application. The image may be a still image or a moving image. The image described below may refer to a moving image (or video content).

[0067] According to one embodiment, the gallery application may provide a function to change the playback speed of a video, thereby performing deceleration playback (or slow motion playback) and acceleration playback (or fast motion). The processor (210) may change the playback speed of a video according to a predetermined user input while a specific video is being played in the gallery application. For example, the processor (210) may decelerate the video in response to a touch and hold input in the video playback area and / or a touch input for selecting a specific playback speed from a playback speed selection item. The function of decelerating the video according to a predetermined user input may be referred to as instant slow motion.

[0068] According to one embodiment, the processor (210) may play a selected image at a first speed based on user input through the gallery application. Here, the first speed may be a constant speed (or 1x speed), but is not limited thereto. For example, the electronic device (200) may display thumbnails of each image in the thumbnail area in the gallery application and display the image of the selected thumbnail in the image playback area.

[0069] According to one embodiment, the processor (210) may detect a first user input that triggers slow-down playback (or slow motion) of the video while the video is being played at a first speed (e.g., constant speed playback). According to one embodiment, the touch input that triggers slow-down playback may include a touch (or tap) and a hold action of maintaining the touch on an area of ​​the display (230) (e.g., an area for playing a video where a video is displayed), and if the touch and hold time is longer than a predetermined time, slow-down playback of the video may be triggered.

[0070] According to one embodiment, the processor (210) may, in response to a first user input, reduce the playback speed of an image being displayed in the image playback area. For example, the processor (210) may change the playback speed of the image from a first speed to a second speed. In this document, the second speed may be a playback speed different from the first speed. For example, the second speed may be, but is not limited to, 1 / 4 speed, which is slower than the first speed, or the second speed may be, but is not limited to, 2x speed, which is faster than the first speed.

[0071] According to one embodiment, the processor (210) can provide a slow motion effect while maintaining the same frame rate (or frame per second) by interpolating pixel data of preceding and following frames between each frame during slow-down playback of the video and inserting and outputting the interpolated frame(s). Alternatively, the processor (210) can output the video by lowering the frame rate of the video according to the slow-down playback ratio.

[0072] In one embodiment, the processor (210) may, in response to the release of the first user input (e.g., release of a touch), return the playback speed of the video to the first speed (e.g., constant playback). Accordingly, the user may select a desired section for slow-down playback with a simple user input (e.g., touch and hold).

[0073] According to one embodiment, the processor (210) may, in response to the release of the first user input, display on the display (230) a slow motion storage item (or a first graphic item) that allows the user to select to store an image played at a second speed (e.g., slowed down or accelerated). For example, the electronic device (200) may display the slow motion storage item by overlaying it on an image being played at a regular speed in the image playback area. The processor (210) may remove the display of the slow motion storage item if no user input for the slow motion storage item is received for a predetermined period of time.

[0074] In one embodiment, the processor (210) may store a video (or slow motion video) played at a second speed in the memory (220) in response to a second user input for a slow motion storage item. The second user input may include a touch input for the slow motion storage item. The processor (210) may store a fast motion video played at an accelerated speed in the memory (220) in response to a second user input for a fast motion storage item.

[0075] According to one embodiment, the processor (210) may, in response to a second user input, store the video (or slow motion video, fast motion video) played at the second speed as a separate file from the original video, or store information related to slow playback (or accelerated playback). For example, the processor (210) may create a new video file including interpolation frames inserted between each frame for slow playback, and store the new video file in the memory (220). Alternatively, the processor (210) may store information on the time section played at slow playback speed and playback speed information in the original video without separately storing a slow motion video file.

[0076] The process of providing a slow motion save item after slow motion playback of a video and saving the slow motion played video will be described in more detail with reference to FIGS. 4 and 5.

[0077] According to one embodiment, when storing a slow motion video, the processor (210) may store a time section played back (or slowed down) at a second speed from the start time of the first user input to the release time of the first user input. Alternatively, the processor (210) may further include and store additional time before and after the section played back at the second speed. For example, the processor (210) may store a video of a time section from a first time point, which is a predetermined time before the start time of the first user input, to a second time point, which is a predetermined time after the release time of the first user input. Alternatively, the processor may store a video of a time section from the start time of a scene including the time section in which the first user input is input to the time section at which it transitions to another scene. When the processor (210) additionally stores a section other than the slowed down section, the additional section may be stored as a regular speed playback section or as an accelerated playback section (e.g., 2x speed).

[0078] Examples of video storage sections will be described in more detail with reference to Fig. 7.

[0079] According to one embodiment, if multiple slow-down playbacks (or accelerated playbacks) have been recorded for a specific video, the processor (210) may determine a time interval for storing and / or sharing the video based on the recorded slow-down playback history (or accelerated playback history). According to one embodiment, the processor (210) may recommend a time interval for storing and / or sharing the video to the user. This embodiment will be described in more detail with reference to FIG. 8.

[0080] According to one embodiment, the processor (210) may perform an operation to share the video played at the second speed with another device if a shared item (or a second graphic item) is selected within a predetermined time based on a third user input after playing the video at the second speed (or slowing down playback, speeding up playback) based on a first user input. For example, if a third user input is received while a slow motion storage item (or a first graphic item) is displayed, the processor (210) may share the slow motion video played at a slow speed with another device. Alternatively, if a third user input is received while a fast motion storage item is displayed, the processor (210) may share the fast motion video played at an accelerated speed with another device.

[0081] According to one embodiment, when a sharing item is selected based on a third user input, the processor (210) displays an icon of an application (e.g., quick share, message, email, photo, drive) that provides a sharing function, and can share slow motion video with another device using the application of the icon selected based on the user input.

[0082] The process of sharing the slow-down playback of a video with another device after slow-down playback is described in more detail with reference to Fig. 6.

[0083] According to one embodiment, the processor (210) may display a playback control item that allows selection of starting or pausing playback of the video during playback of the video. When a user input (e.g., a fourth user input) is received for the playback control item (or a third graphic item) while the video is being played at a second speed, the processor (210) may remove the display of the playback control graphic item and display a playback speed selection item (or a fourth graphic item) that allows selection of the playback speed of the video. For example, the fourth user input may include a touch (or tap) and hold input for the playback control item. When the touched time for the playback control item reaches a predetermined time (e.g., 1 second), the processor (210) may change the playback control item to a playback speed selection item.

[0084] In one embodiment, the playback speed selection item may include selectable playback speeds (e.g., 0.5x, 1x, 2x). The processor (210) may change the playback speed of the video based on the selected playback speed according to user input. The process of changing the playback control item to a playback speed selection item will be described in more detail with reference to FIG. 12.

[0085] According to one embodiment, the processor (210) can change the playback speed of an image based on the movement of a user input while the image is being displayed in slow-down playback. This embodiment will be described in more detail with reference to FIGS. 13 and 14.

[0086] According to one embodiment, when a first user input triggering a change in the playback speed is received while a video is being played, the processor (210) may analyze the content provided in the video being played to determine the playback speed of the video. For example, the processor (210) may extract at least one object included in the video, and determine whether to play the video at a reduced speed, maintain playback at a constant speed, or play it at an increased speed by analyzing the position, size, angle, and / or movement of the extracted object. This embodiment will be described in more detail with reference to FIGS. 15 to 20 .

[0087] According to one embodiment, when multiple objects are present in an image, the processor (210) may apply slow motion to only some of the objects. For example, the processor (210) may separate layers by object within the image and decelerate playback only for the layer containing the object selected by the user. This embodiment will be described in more detail with reference to FIG. 21.

[0088] According to one embodiment, the processor (210) may provide additional graphic effects that can enhance the slow motion effect when playing back a video at a reduced speed based on a first user input. This embodiment will be described in more detail with reference to FIG. 22.

[0089] Instructions for performing the operations of the electronic device (200) (or processor (210)) described above may be stored in a computer-readable recording medium. The recording medium may be tangible and non-transitory. The recording medium may store one or more computer programs including the instructions.

[0090] FIG. 3 illustrates a UI that provides a slow motion function of an image according to one embodiment.

[0091] According to one embodiment, an electronic device (e.g., electronic device (200) of FIG. 2) can play an image stored in a memory (e.g., memory (220) of FIG. 2) through a gallery application and display the image on a display (e.g., display of FIG. 2).

[0092] Referring to (a), (b), and (c) of FIG. 3, the gallery application may include a video playback area (310), a thumbnail area (320), a top menu area (340), and a bottom menu area (330).

[0093] According to one embodiment, a video being played may be displayed in the video playback area (310). The electronic device may display a playback control item (312) that allows selection of playing or pausing the video, a capture item (314) that allows capturing the video, and / or a volume control item (316) by overlaying them on the video playback area (310).

[0094] According to one embodiment, thumbnails of images stored in memory may be displayed in the thumbnail area (320). The thumbnail area (320) may be scrolled left and right in response to a user's touch input. The electronic device may display an image corresponding to a thumbnail selected in response to a user input in the thumbnail area (320) on the image playback area.

[0095] According to one embodiment, the top menu area (340) may display a smart view item (342) that can share an image to an external device (e.g., TV, tablet PC), an AI service item (344) that can execute an AI-based service (e.g., Bixby vision) for the image, and a rotation item (346) that can rotate the orientation from a portrait view to a landscape view.

[0096] According to one embodiment, the bottom menu area (330) may display a favorite item (311), an edit item (313), a share item (315), a delete item (317), and a more item (319).

[0097] The gallery application screen illustrated in FIG. 3 and other drawings corresponds to one embodiment, and the types, shapes, locations, and / or functions of items provided on the gallery application are not limited to the described contents.

[0098] Referring to (a) of FIG. 3, an electronic device (200) (e.g., the electronic device (200) of FIG. 2) can play a selected image at a constant speed according to a user input through a gallery application and display the selected image on an image playback area (310). The gallery application may further include a thumbnail area (320) that displays thumbnails of images stored in memory, a top menu area (340) that provides various option menus related to the displayed image, and a bottom menu area (330).

[0099] The electronic device (200) can detect a user's touch input that triggers slow motion (or slow-down playback) of an image on the display. For example, a touch input that triggers slow motion may include a touch (or tap) and hold input on an area of ​​the display. The electronic device (200) can trigger slow motion when the touched time reaches a predetermined time (e.g., 1 second).

[0100] Referring to (b) of FIG. 3, the electronic device (200) may, in response to a user input, decelerate playback (or slow motion playback) of an image being displayed in the image playback area (310). For example, the electronic device (200) may play back the image at a predetermined speed of 1 / 4, but the playback speed is not limited thereto. According to one embodiment, the electronic device (200) may provide a slow motion effect while maintaining the same frame rate (or frame per second) by inserting and outputting interpolated frame(s) generated by interpolating pixel data of preceding and succeeding frames between each frame. For example, in the case of a 60 fps image, three interpolated frames generated by interpolating preceding and succeeding frames may be inserted between each frame, thereby increasing the number of frames by four times compared to the original image and allowing the image to be displayed at 1 / 4 speed compared to the original image. Alternatively, the electronic device (200) may output the image by lowering the frame rate of the image according to the deceleration playback ratio.

[0101] Referring to (c) of FIG. 3, when the user input is released, the electronic device (200) can stop slow-down playback and resume playback of the video being displayed in the video playback area (310) at regular speed.

[0102] Hereinafter, the second speed of the video that changes according to the first user input is described as slow-down playback, but the various embodiments of this document are not limited thereto. For example, the electronic device (200) may, in response to the first user input, accelerate video playback, store the accelerated fast-motion video, and / or share it with other devices.

[0103] FIG. 4 is a flowchart of a method for storing and sharing slow motion video (or fast motion video) according to one embodiment.

[0104] According to one embodiment, the illustrated method may be performed by an electronic device (e.g., the electronic device (200) or processor (210) of FIG. 2), and the technical features described above may be omitted from the description below.

[0105] According to one embodiment, in operation 410, the electronic device may execute a gallery application. The gallery application may provide a function to change the playback speed of the video, thereby providing deceleration playback (or slow motion playback) and acceleration playback (or fast motion).

[0106] According to one embodiment, in operation 420, the electronic device may play (or play at constant speed) the selected image at a first speed according to a user input. Here, the first speed may be constant speed (or 1x speed). The electronic device may play and display the image (e.g., a video, video content) selected by the user on the gallery application.

[0107] In one embodiment, at operation 430, the electronic device may determine whether a first user input is received. The first user input may be a user input that triggers slow-motion playback of a video, and may include a touch (or tap) and a hold action of maintaining the touch on an area of ​​the display (e.g., an area of ​​a video playback where a video is displayed).

[0108] In one embodiment, at operation 440, the electronic device may play (or decelerate or accelerate) the video at a second speed in response to the first user input. Here, the second speed may be slower than the first speed, and may be, but is not limited to, 1 / 4 speed. In another embodiment, the second speed may be faster than the first speed, and may be, but is not limited to, 2x speed.

[0109] In one embodiment, at step 450, the electronic device may determine whether the first user input is released. For example, the electronic device may determine whether the touch is released from a touch-and-hold state. In response to the release of the first user input, the electronic device may restore the playback speed of the video to the first speed (e.g., constant speed).

[0110] In one embodiment, at operation 460, the electronic device may, in response to the release of the first user input, display a first graphic item (or slow motion storage item). The first graphic item may be a selectable item that allows the user to select to store the image played at a second speed (or played at a reduced speed, played at an accelerated speed).

[0111] According to one embodiment, at operation 470, the electronic device may determine whether a second user input (e.g., a touch input) is received for the first graphic item.

[0112] In one embodiment, at operation 480, the electronic device may store the video played at the second speed. For example, in response to a second user input, the electronic device may store the video played at the second speed (or slow motion video, fast motion video) as a separate file from the original video, or store information related to slow playback (or accelerated playback).

[0113] According to one embodiment, instructions for performing each operation constituting the method may be stored in a tangible, non-transitory computer-readable recording medium.

[0114] FIG. 5 illustrates a UI that provides storage of slow motion video according to one embodiment.

[0115] Referring to (a) of FIG. 5, the electronic device (200) can play a selected image (e.g., a video, video content) at a first speed according to user input through a gallery application and display the selected image on the image playback area (310). Here, the first speed may be a constant speed playback, the same as the original image, or the image may be played at a different playback speed depending on the user's settings.

[0116] According to one embodiment, the electronic device (200) may detect a first user input that triggers a change in the playback speed of an image on the display. For example, the first user input may include a touch (or tap) and hold input on an area of ​​the display. The electronic device (200) may trigger a change in the playback speed when the touched time reaches a predetermined time (e.g., 1 second).

[0117] Referring to (b) of FIG. 5, the electronic device (200) may, in response to a first user input, play back (or slow down playback, accelerated playback) a video at a second speed. For example, the second speed may be a playback speed slower than the first speed, such as 1 / 4 speed, but is not limited thereto. Alternatively, the second speed may be a playback speed faster than the first speed, such as 2x speed, but is not limited thereto. According to one embodiment, when the electronic device (200) slows down playback of a video at the second speed, it may insert and output interpolated frame(s) generated by interpolating pixel data of preceding and following frames between each frame, or may lower the frame rate of the video and output it according to the rate of slow down playback.

[0118] Referring to (c) of FIG. 5, when the first user input is released, the electronic device (200) can return the video playback speed from the second speed back to the first speed (e.g., constant speed).

[0119] According to one embodiment, the electronic device (200) may provide a slow motion storage item (510) (or a first graphic item) that allows selection of saving a video played at a second speed in response to the release of the first user input. For example, the electronic device (200) may display the slow motion storage item (510) by overlaying it on a video played at a constant speed on the video playback area (310). The slow motion storage item (510) may be displayed by overlaying it on a video played at a constant speed at the top of the video playback area (310), but the position of the slow motion storage item (510) is not limited thereto. According to another embodiment, the electronic device (200) may provide a fast motion storage item that allows selection of saving a video played at an accelerated speed in response to the release of the first user input.

[0120] According to one embodiment, the slow motion storage item (510) may include text information (e.g., save slow motion clip) indicating that a video played at a second speed (or played at a reduced speed) can be saved and / or a thumbnail of the video. The slow motion storage item (510) may be a selectable item based on a user's touch input. The electronic device (200) may remove the display of the slow motion storage item (510) if no user input for the slow motion storage item (510) is received for a set period of time.

[0121] According to one embodiment, the electronic device (200) may store a video (or slow motion video) played at a second speed in memory in response to a second user input for the slow motion storage item (510). The second user input may include a touch input for the slow motion storage item (510). Alternatively, the second user input may include various types of input, such as a hovering input (or proximity input), a predetermined voice input, and / or a movement (e.g., shaking) of the electronic device (200) for the slow motion storage item (510).

[0122] According to one embodiment, the electronic device (200) may, in response to a second user input, store the video (or slow motion video, fast motion video) played at the second speed in a memory (e.g., memory (220) of FIG. 2) as a separate file from the original video, or store information related to slow-down playback in the memory.

[0123] According to one embodiment, the electronic device (200) may create a new video file including interpolation frames inserted between each frame for slow-down playback and store it in memory. For example, in the case of a 60 fps video, when slow-down playback at 1 / 4 speed, three interpolation frames interpolated from the preceding and following frames may be inserted between each frame, and the electronic device (200) may store the file including the inserted interpolation frames as a separate file from the original video.

[0124] According to another embodiment, the electronic device (200) may store information on the time section played back at reduced speed and playback speed information from the original video, without separately storing the slow motion video file. In this case, when a request for playback of a slow motion video is made through the gallery application, the electronic device (200) may generate a slow motion video using the original video and the information on the time section played back at reduced speed and playback speed information stored above, and display the generated slow motion video.

[0125] Referring to (d) of FIG. 5, when a slow motion video is stored, the electronic device (200) can generate a thumbnail thereof and display it in the thumbnail area. The electronic device (200) can display the thumbnails of the slow motion video so as to be distinguished from the thumbnails of the general video.

[0126] FIG. 6 illustrates a UI that provides sharing of slow motion video according to one embodiment.

[0127] Referring to (a) of FIG. 6, the electronic device (200) can play (or constant speed playback) a video selected through a gallery application according to user input at a first speed and display it on the video playback area (310). Here, the first speed may be the same constant speed playback as the original video, or may be played at a different playback speed depending on the user's settings.

[0128] Referring to (b) of FIG. 6, the electronic device (200) may, in response to a first user input, play (or slow down) the video at a second speed. For example, the second speed may be a playback speed slower than the first speed, such as 1 / 4 speed, but is not limited thereto.

[0129] Referring to (c) of FIG. 6, when the first user input is released, the electronic device (200) can return the playback speed of the video to the first speed (e.g., constant speed).

[0130] In one embodiment, the electronic device (200) may provide a slow motion storage item (510) (or a first graphic item) that allows the user to select to store an image played at a second speed (or played at a reduced speed) in response to a first user input being released. The electronic device (200) may display the slow motion storage item (510) for a set period of time.

[0131] According to one embodiment, as illustrated in (a) to (c) of FIG. 6, while the electronic device (200) plays a video in the gallery application, the electronic device (200) may display a bottom menu area (330) including a favorite item, an edit item, a share item (610), a delete item, and a more item at the bottom of the video playback area (310). The share item (610) may provide a function for sharing the played video with another device. For example, when the share item (610) is selected according to a user input, the electronic device (200) may share the video played on the video playback area (310) with another device using an application (or function) such as quick share, message, email, photo, or drive. The shape and / or position of the share item (610) is not limited to that illustrated in FIG. 6.

[0132] According to one embodiment, if a share item (610) is selected based on a third user input within a predetermined time period after playing the video at the second speed, the electronic device (200) may perform an operation to share the video played at the second speed with another device. For example, if a third user input is received while the slow motion storage item (510) is displayed, the electronic device (200) may share the slow motion video played at the second speed (or played at a reduced speed) with another device. Alternatively, if the share item (610) is selected after a predetermined time period has elapsed and / or after the slow motion storage item (510) has been removed, the electronic device (200) may share the original video played at a constant speed with another device.

[0133] Referring to (d) of FIG. 6, when a shared item (610) is selected according to a third user input, the electronic device (200) can display a thumbnail of a slow motion video and icons of applications that provide a sharing function, such as quick share (621), message (622), email (623), photo (624), and drive (625). When any one of the displayed icons (621, 622, 623, 634, 625) is selected, the electronic device (200) can share the slow motion video with another device using the application of the selected icon.

[0134] In Fig. 6, an embodiment of slowing down a video and then sharing the slow-motion video that has been slowed down with another device is described, but an embodiment of speeding up a video and then sharing the fast-motion video that has been speeded up with another device is also possible.

[0135] FIG. 7 illustrates a storage section of a slow motion video according to one embodiment.

[0136] According to one embodiment, an electronic device (e.g., electronic device (200) of FIG. 2) may store a slow motion video (or a slow motion video) in a memory (e.g., memory (220) of FIG. 2) in response to a user input for a slow motion storage item after slowing down the video. The electronic device may store the slow motion video including only the slowed down time section, or may store the slow motion video including additional sections before and after the slowed down time section.

[0137] Referring to FIG. 7, in a video played in a gallery application of an electronic device, time points t1 to t6 may include different characteristics from previous or subsequent sections. For example, between time points t1 to t6, changes in objects, such as movement, movement, and / or speed changes of at least one object (e.g., a person, an object), or changes in scenes, such as transitions from one scene to another, may occur. Additionally, a user input triggering slow motion (or playback at a second speed) may be input at time point t3 and released at time point t4, and the video may be played at 1 / 4 speed during that section.

[0138] According to one embodiment, the electronic device can store a slow motion video of a first section (722) that includes only the section between time points t3 and t4, which is the section in which slow motion playback is performed.

[0139] According to another embodiment, the electronic device can store the decelerated playback section and the set time before and after the decelerated playback as a slow motion video. For example, the electronic device can store the video of the second section (724) from t2 before t3 when the decelerated playback starts to t5 after t4 when the decelerated playback ends as a slow motion video. In this case, the electronic device can store the decelerated playback section t3 to t4 at 1 / 4 speed, and store the sections t2 to t3 and t4 to t5 other than the decelerated playback as a video played at a constant speed or as a video played at an accelerated speed (e.g., at 1.1 times or more). Accordingly, the slow motion effect in the decelerated playback section between t3 and t4 can be emphasized.

[0140] According to another embodiment, the electronic device may store the third section (726) of t1 to t6, which is the section in which a change in an object or scene in the video occurs, as a slow motion video. For example, the electronic device may analyze the running video to analyze the start time t1 and the end time t6 of the scene. The electronic device may store the slow-down playback sections t3 to t4 at 1 / 4 speed, and store the sections t1 to t3 and t4 to t6, which are sections other than the slow-down playback, as a video played at a constant speed or as a video played at an accelerated speed (e.g., at 1.1 times or more).

[0141] FIG. 8 illustrates a storage section of a slow motion video according to one embodiment.

[0142] According to one embodiment, an electronic device (e.g., the electronic device (200) of FIG. 2) may record information about a section of a specific video that has been slowed down based on a user input. If multiple slowed down playbacks have been recorded for a specific video, the electronic device may determine a time section of the video to be stored and / or shared, and / or recommend such a time section to the user, based on the recorded slowed down playback history.

[0143] Referring to FIG. 8, the electronic device can store multiple slow-down playback histories for a specific video. For time intervals (812, 814) in which the time at which the first user input was entered is less than a predetermined time (e.g., 1 second), the electronic device can recognize that the user did not intend slow-down playback and exclude them from the selection of storage / sharing intervals.

[0144] According to one embodiment, the electronic device may determine a time section to be stored / shared based on the number of deceleration playbacks, the length of the deceleration playback, and / or the time of the deceleration playback. For example, referring to FIG. 8, the electronic device may determine a first recommended section (832), which is a time section in which the first deceleration playback (822), the second deceleration playback (824), and the third deceleration playback (826) overlap, i.e., a time section in which three deceleration playbacks occur, as a time section to be stored / shared, based on the number of deceleration playback sections. Alternatively, the electronic device may determine a second recommended section (834), which is a time section of the third deceleration playback (826) that was decelerated the longest, as a time section to be stored / shared. Alternatively, the electronic device may determine a third recommended section (836), which is a time section of the fourth deceleration playback (828) that was decelerated the most recently, as a time section to be stored / shared.

[0145] According to one embodiment, the electronic device may recommend a first recommended section (832), a second recommended section (834), and a third recommended section (836) to the user, and store a slow motion video of at least one recommended section selected based on the user's selection, and / or share it with another device.

[0146] In another embodiment, the electronic device may analyze content within a video to determine a time interval to be stored / shared. For example, based on information such as object movement and scene changes in the video, the electronic device may determine and / or recommend to the user a time interval including at least one of the first, second, and third determined intervals as the time interval to be stored / shared.

[0147] FIG. 9 illustrates a UI that allows selection of a storage section of a slow motion video according to one embodiment.

[0148] According to one embodiment, when multiple slowdown playbacks are performed for a specific video, the electronic device (200) may determine at least one time interval to be stored / shared based on a slowdown playback history (e.g., number of slowdown playbacks, slowdown playback length, and / or slowdown playback time). The electronic device (200) may provide the determined at least one recommended interval to the user through a UI, and may store and / or share with other devices at least one time interval selected based on user input.

[0149] According to one embodiment, the electronic device (200) may provide at least one recommended section through a visual cue in the form of a filmstrip. Referring to (a) of FIG. 9, the electronic device (200) may display a film strip area (910) including thumbnails of specific frames of a video at the bottom of the video playback area.

[0177] According to one embodiment, an electronic device (e.g., the electronic device (200) of FIG. 2) may change the playback speed of a video based on the movement of the user input while the video is being displayed in a slow-down playback mode in the video playback area of ​​a gallery application while a user input (e.g., a touch and hold) is maintained. In this case, the electronic device may display an item indicating slow-down playback or accelerated playback close to or partially overlapping the location of the user input.

[0178] Referring to (a) of FIG. 14, when a user's touch input is maintained for a set period of time (e.g., 1 second) during constant-speed playback of a video, the electronic device may display items (1410, 1420) indicating slow-down playback and accelerated playback. For example, the current position of the user input may correspond to slow-down playback, and movement to the right may correspond to accelerated playback. According to one embodiment, the electronic device may change the accelerated playback speed based on the movement distance when the user input moves to the right. For example, the playback speed of the video may be changed to become faster as the user input moves further to the right.

[0179] According to one embodiment, the electronic device may display (1410) an item indicating slow playback and accelerated playback overlapping the location of the user input, or display it at a location (1410) adjacent to the user input that does not overlap.

[0180] Referring to (b) of FIG. 14, the electronic device can be controlled to change the playback speed according to the leftward and rightward movements of the user input. For example, items (1420, 1422) indicating slow playback and accelerated playback can include information indicating that the playback speed is changed slowly when moving to the left from the current position of the user input, and that the playback speed is changed quickly when moving to the right. The electronic device can display the items indicating slow playback and accelerated playback by overlapping them (1420) at the position of the user input, or display them at a position (1422) adjacent to the user input that does not overlap.

[0181] According to one embodiment, the electronic device can control the playback speed of a video to slow down when the user moves the touch position to the left, and to slow down the playback speed as the distance moved to the left increases. Additionally, the electronic device can control the playback speed of a video to speed up when the user moves the touch position to the right, and to speed up the playback speed as the distance moved to the right increases.

[0182] FIG. 15 illustrates a method for executing slow motion based on the position of an object within an image according to one embodiment.

[0183] According to one embodiment, when an electronic device (e.g., the electronic device (200) of FIG. 2) receives a first user input (e.g., a touch and hold) for slowing down playback of an image, the electronic device may determine a time section suitable for slowing down playback through image analysis. According to one embodiment, the electronic device may determine a section for changing the playback speed and a section for constant playback through analysis of the position, size, angle, and / or movement of an object within the image.

[0184] According to one embodiment, the electronic device may analyze the currently displayed image to determine a shooting composition, and determine a region of interest within the image based on the shooting composition. For example, as in FIG. 15, when the image (1500) is displayed in a three-part composition, the area within the two-thirds point including the center area of ​​the image (1500) may be designated as a region of interest (1510), and when a subject (1520) is located within the region of interest (1510), the image (1500) may be played back at a reduced speed in response to a first user input. When the subject (1520) is not located within the region of interest while the first user input is being input, the electronic device may play back the image (1500) at a constant speed or play back at an accelerated speed.

[0185] The three-part composition and region of interest of FIG. 15 are examples, and the present embodiment can be applied to various types of shooting compositions. For example, the electronic device can determine the current image currently being displayed as one of various compositions such as a two-part composition, a diagonal composition, a mountain composition, a circular composition, a diagonal composition, a contrast composition, a symmetrical composition, and an S-shaped composition, and can determine whether a subject is located within the region of interest determined in each shooting composition. If a specific subject is located within the region of interest determined in each shooting composition, the electronic device can provide slow-down playback according to a first user input.

[0186] FIG. 16 illustrates a method of executing slow motion according to the size of an object in an image according to one embodiment.

[0187] According to one embodiment, an electronic device (e.g., electronic device (200) of FIG. 2) may determine the playback speed of an image based on the size of an object within the image. For example, when a first user input is being input, the electronic device may decelerate playback if the size of a specific object within the image is large, and may play at a constant speed or accelerate playback if the size is small. Alternatively, the electronic device may determine whether to decelerate playback only when a specified condition is satisfied based on the size of the object.

[0188] According to one embodiment, in the case of an image of a person, the electronic device may determine the playback speed based on the type of camera shot of the image. For example, the camera shots may be classified as extreme long shot, long shot, full shot, medium full shot, medium shot, medium close-up, close-up, and extreme close-up based on the size and / or proportion of the person in the image. The electronic device may slow down playback based on the type of camera shot while a first user input (e.g., touch and hold) is input, or slow down playback after further checking whether a specified condition is satisfied, or may not slow down playback.

[0189] Figure 16 (a) may be a close-up shot (1610) in which only the facial area of ​​a subject is captured in a large size. In this case, the electronic device may determine the size of the captured subject and / or the type of camera shot, and may slow down the video playback according to the first user input. Alternatively, the electronic device may recognize the subject's facial area and slow down the video playback if the facial expression is in a specific shape and / or if an emotion is detected.

[0190] Figure 16 (b) may be a medium shot (1620) in which the subject, a person, is captured in a medium size, with the face and upper body area. In this case, the electronic device may slow down the video when a first user input is received and a predetermined condition is satisfied. For example, the electronic device may slow down the video when movement and / or movement of the person in the video is detected.

[0191] Figure 16 (c) may be a long shot (1630) in which the subject, a person, is photographed in a small size and with the entire body covered. In this case, the electronic device may determine that the scene is not the main scene intended by the user, and may play the video at a constant speed or at an accelerated speed without slowing it down despite the first user input.

[0192] FIG. 17 illustrates a method of executing slow motion according to a portion of an object displayed in an image according to one embodiment.

[0193] According to one embodiment, an electronic device (e.g., electronic device (200) of FIG. 2) may determine the playback speed of an image based on the angle or posture of an object within the image when a first user input is input. For example, the electronic device may slow down the playback speed of an image when a person, which is the main subject of the image being played, is recognized, the angle of the person is frontal, both eyes appear within the image, and / or facial recognition is possible.

[0194] Referring to (a) of FIG. 17, a person (1712) in an image (1710) is looking straight ahead, so that the entire facial area can be recognized, and in this case, the electronic device can slow down the image (1710) in response to a first user input.

[0195] Referring to (b) of Fig. 17, movement of the person (1722) may occur, causing a portion of the face to not be recognized. In this case, the electronic device may stop the slow-down playback of the image (1720) and resume normal playback, or increase the speed of the slow-down playback (e.g., from 1 / 4 speed to 1 / 2 speed).

[0196] Referring to (c) of Fig. 17, movement of a person (1732) may occur, causing the face not to be recognized and reducing the size of the person (1732). In this case, the electronic device may play the image (1730) at a constant speed even while the first user input is maintained.

[0197] In one embodiment, the electronic device can determine whether to slow down playback based on the brightness of the image. For example, even if the entire face of a person is visible in the image, as shown in (a) of FIG. 17, if the brightness of the image is high enough to allow face recognition, the image can be slowed down. Conversely, if the brightness is low enough to make face recognition impossible, the image can be played at a constant speed or accelerated, regardless of the first user input.

[0198] FIG. 18 illustrates a method for executing slow motion according to the position and size of an object in an image according to one embodiment.

[0199] According to one embodiment, an electronic device (e.g., the electronic device (200) of FIG. 2) may determine a playback speed of an image based on the size and / or position of an object within the image when a first user input is input. For example, the electronic device may slow down playback of the image when the size of the object within the image is greater than or equal to a reference value and / or is located in the center of the image, and may play the image at a constant speed or at multiple speeds when the size of the object is less than or equal to the reference value and / or is located at the edge of the image.

[0200] Referring to (a) of FIG. 18, the size of the person (1812), which is an object in the image (1810), may be recognized as small. In this case, the electronic device may play the image (1810) at a constant speed or play it at an accelerated speed (e.g., 2x speed), despite the first user input.

[0201] Referring to (b) of Fig. 18, the size of the person (1822) is recognized as being larger than the reference size, but the location may be at the edge rather than the center. In this case, the electronic device may play the image (1820) at a constant speed or play it at an accelerated speed (e.g., 2x speed) despite the first user input.

[0202] Referring to (c) of Fig. 18, the size of the person (1832) is larger than the reference size, and its location can be recognized as being in the center. In this case, the electronic device can, in response to the first user input, play the image (1830) at a reduced speed (e.g., 1 / 4 speed).

[0203] FIG. 19 illustrates a method for executing slow motion according to the movement of an object in an image according to one embodiment.

[0204] According to one embodiment, when a first user input is detected, the electronic device may analyze the movement of an object within the video and, based on the magnitude and / or speed of the movement, determine whether to slow down playback.

[0205] Referring to (a) of Fig. 19, it can be confirmed that the person (1912), which is an object in the image (1910), has small and slow movements. In this case, the electronic device can play the image (1910) at a constant speed even while the first user input is maintained.

[0206] Figures 19 (b) and (c) show figures (1922, 1932) swinging, with large arm movements and possibly rapid speeds. In this case, the electronic device can play back the images (1920, 1930) at reduced speed (e.g., 1 / 4 speed).

[0207] Referring to (d) of Fig. 19, a character object may disappear from the video as the scene changes. In this case, the electronic device can resume playback of the video (1940) at a constant speed.

[0208] FIG. 20 illustrates a method of executing slow motion according to the position and size of an object selected in an image according to one embodiment.

[0209] According to one embodiment, when a first user input is input, an electronic device (e.g., electronic device (200) of FIG. 2) may analyze an object within an image and determine whether to slow down playback based on the state of the object (e.g., size, position, angle, movement). When a plurality of objects are included within an image, the electronic device may determine whether to slow down playback of the image based on the state of at least one object selected according to the user input.

[0210] Referring to (a) of FIG. 20, multiple people may appear in an image (2010). In this case, the electronic device may receive user input regarding person A (2012) among the multiple people. For example, the electronic device may use object analysis techniques to recognize objects within the image and display the recognized objects so that they are visually distinct from the background. The electronic device may receive a selection regarding person A (2012) among the objects.

[0211] Referring to (b) of Fig. 20, the person A (2022) selected according to the user input may be positioned at the edge of the image (2020). In this case, the electronic device may maintain constant playback speed without slowing down the image (2020) according to the position of the person A (2022).

[0212] Referring to (c) of Fig. 20, as person A (2032) moves, person A (2032) may be positioned in the center area and may be large in size. In this case, the electronic device may determine that it is a slow-down playback section based on the position and size of person A (2032) and play the video (2030) at a slow-down speed (e.g., at 1 / 4 speed).

[0213] Referring to (d) of FIG. 20, the size of person A (2042) may decrease as the person A (2042) moves. In this case, the electronic device may accelerate playback of the video (2040) (e.g., at 2x speed) to quickly skip the corresponding section.

[0214] Referring to (e) of FIG. 20, person A (2052) can be placed again in a large size in the center of the image. In this case, the electronic device can again play the image (2050) at a reduced speed.

[0215] According to one embodiment, when a different object (or person) from among multiple objects (or people) in an image is selected based on a user input, the playback speed of the image can be determined based on the state (e.g., size, position, angle, movement) of the object.

[0216] In one embodiment, the electronic device may slow down the playback of a video based on the state of the person in focus, such as a portrait video.

[0217] FIG. 21 illustrates a method of applying slow motion to some objects in an image according to one embodiment.

[0218] According to one embodiment, when there are multiple objects in an image, the electronic device (200) may apply slow motion to only some of the multiple objects. For example, the electronic device (200) may separate layers by object within the image and decelerate playback only for the layer containing the object selected by the user.

[0219] Referring to (a) of FIG. 21, a train (2110) may be selected from among objects in the image based on a user input. For example, if a first user input (e.g., touch and hold) is input in an area where a train is displayed during regular playback of the image, the electronic device (200) may determine that slow-down playback is requested only for the layer including the train (2110).

[0220] Referring to (b) of FIG. 21, the electronic device (200) can decelerate playback only for the selected object, the train (2120), and maintain constant playback for the remaining areas.

[0221] According to this embodiment, slow-down playback is applied only to objects (2110, 2120) that appear blurry due to their fast movement speed during constant-speed playback, so that the entire video can be viewed clearly.

[0222] FIG. 22 illustrates a method for providing graphic effects during slow motion playback according to one embodiment.

[0223] According to one embodiment, the electronic device (200) may provide additional graphic effects when slowing down the playback of a video based on a first user input. For example, the electronic device (200) may recognize objects and / or backgrounds in the video and provide graphic effects that enhance the slow motion effect.

[0224] Referring to (a) of FIG. 22, while an image is being played in the image playback area (310), the electronic device (200) can receive a first user input (2215) (e.g., touch and hold).

[0225] Referring to (b) of FIG. 22, the electronic device (200) may slow down the video being played (e.g., at 1 / 4 speed) in response to a first user input. The electronic device (200) may display an additional graphic effect item (2210) in the video playback area (310) and receive a user input for the additional graphic effect item (2210).

[0226] Referring to (c) of FIG. 22, the electronic device (200) may provide a graphic effect (2230) while slowing down the playback of a video. For example, the electronic device (200) may recognize that the background of the currently playing video is snowy and that a blizzard is occurring according to the user's movements. The electronic device (200) may provide a graphic effect (2230) of a lot of snow falling corresponding to the scene, and provide it together with the slow motion video.

[0227] As another example, if the electronic device (200) recognizes the video as a situation where flower petals are falling, it can provide a graphic effect of more flower petals falling when the video is played back at a slow speed.
