[0032] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0033] To facilitate understanding, the concepts involved in the embodiments of the present disclosure are explained below.

[0034] Electronic device: is a device with wireless transceiver function. The electronic device can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted. The electronic device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) electronic device, an augmented reality (AR) electronic device, a wireless terminal in industrial control, an on-board electronic device, a wireless terminal in self-driving, a wireless electronic device in remote medical care, a wireless electronic device in smart grid, a wireless electronic device in transportation safety, a wireless electronic device in smart city, a wireless electronic device in smart home, a wearable electronic device, etc. The electronic device involved in the embodiments of the present disclosure can also be referred to as a terminal, user equipment (UE), an access electronic device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote electronic device, a mobile device, a UE electronic device, a wireless communication device, a UE agent or a UE device, etc. The electronic device can also be fixed or mobile.

[0035] In the related art, a live photo is a dynamic image that can store a video before and after the image is taken, and the user can browse the above video when long pressing the image. Currently, after the user opens the shooting page of the electronic device, the electronic device can start recording the video and save the recorded video in the cache. When the user presses the shooting control, the electronic device can stop the video recording after a period of time, thereby obtaining a long video. The electronic device can intercept a video in the long video based on the moment when the user presses the shooting control, and obtain a live photo in combination with the captured image. However, in the above method, the memory occupied by the electronic device for caching long videos is large. When the user opens the shooting page for a long time, the problem of memory overflow is prone to occur. Moreover, most of the recorded videos are irrelevant to the production of live photos, thereby resulting in a waste of memory resources.

[0036] In order to solve the technical problems in the related art, the embodiment of the present disclosure provides a video processing method, which records a first video segment in response to a touch operation on a shooting control in a shooting page, and determines a third video segment in a plurality of video segments in a preset storage space, wherein, before the touch operation, the preset storage space is used to store one or more recently recorded video segments, and the third video segment is the last video segment recorded before the touch operation. The electronic device can obtain the duration of the third video segment and obtain at least one second video segment in the preset storage space based on the duration of the third video segment. The electronic device can generate a video based on the first video segment and at least one second video segment. In this way, since the electronic device adopts a segmented recording method for video segments, and before the touch operation, the preset storage space can only store the latest recorded video segment and delete the earlier recorded video segments, it can avoid the memory overflow caused by opening the shooting page for a long time, thereby saving the memory resources of the electronic device.

[0037] The application scenario of the embodiment of the present disclosure is described below with reference to FIG1 .

[0038] Figure 1 is a schematic diagram of an application scenario provided by an embodiment of the present disclosure. Please refer to Figure 1, comprising: an electronic device. Among them, the display page of the electronic device is a shooting page, and the shooting page may include a shooting control. When the electronic device displays the shooting page, the electronic device can start recording multiple videos. After the electronic device records video segment 1 and video segment 2, the user clicks the shooting control in the shooting page, the electronic device can continue to record video segment 3, and the electronic device can generate a dynamic image including video segment 2 and video segment 3. In the above method, if the user of the electronic device does not click the shooting control, the video segment 1 can be deleted after the electronic device records video segment 3, which can effectively save memory resources and avoid memory overflow. In addition, through segmented video recording, the flexibility of generating dynamic images can be improved.

[0039] The following detailed description of the technical solution of the present disclosure and how the technical solution of the present disclosure solves the above-mentioned technical problems is provided with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present disclosure will be described below in conjunction with the accompanying drawings.

[0040] FIG2 is a flow chart of a video processing method provided by an embodiment of the present disclosure. Referring to FIG2 , the method may include:

[0041] S201: Record a first video segment in response to a touch operation on a shooting control in a shooting page.

[0042] The execution subject of the embodiments of the present disclosure may be an electronic device or a video processing device provided in the electronic device. The video processing device may be implemented based on software or a combination of software and hardware, which is not limited in the embodiments of the present disclosure.

[0043] Among them, the electronic device may include a shooting application. When the user clicks on the shooting application, the electronic device may display a shooting page. The shooting page may include shooting controls for shooting. In response to the user's touch operation on the shooting control (it can also be a voice control operation, etc., which is not limited to this embodiment of the present disclosure), the electronic device can capture images.

[0044] The first video segment may be a video segment recorded by the electronic device after the user clicks the capture control. For example, when the electronic device displays a capture page, the electronic device may store the video captured by the camera in a cache, and the first video segment may be a video segment captured by the camera after the user clicks the capture control. For example, if the user clicks the capture control at time A, the first video segment may be a video segment captured by the electronic device's camera after time A. If the user clicks the capture control at time B, the first video segment may be a video segment captured by the electronic device's camera after time B.

[0045] Optionally, the duration of the first video segment may be the first duration. For example, if the first duration is 1 second and the user clicks the capture control at time A, the electronic device may store 1 second of video captured by the camera after time A to obtain the first video segment. If the first duration is 2 seconds and the user clicks the capture control at time B, the electronic device may store 2 seconds of video captured by the camera after time B to obtain the first video segment.

[0046] The process of obtaining the first video segment is described below with reference to FIG. 3 .

[0047] Figure 3 is a schematic diagram of a process for obtaining a first video segment provided by an embodiment of the present disclosure. Please refer to Figure 3, comprising: an electronic device. The display page of the electronic device is a shooting page, and the shooting page may include a shooting control. When the electronic device displays the shooting page, the shooting page does not include a shooting object. When the user clicks the shooting control, the shooting page includes a stationary shooting object, and the electronic device can continue to capture n images to obtain a first video segment. The first video segment includes image 1, image 2, ..., image n, wherein each image includes a stationary shooting object, that is, the first video segment can be a video segment captured by the camera of the electronic device after the user clicks the shooting control.

[0048] S202: Obtain at least one second video segment in a preset storage space.

[0049] The second video segment is a video segment recorded before the touch operation. For example, when the electronic device displays a capture page, the electronic device may store the video captured by the camera in a cache, and the second video segment may be a video segment captured by the camera before the user clicks the capture control. For example, if the user clicks the capture control at time A, the second video segment may be a video segment captured by the electronic device's camera before time A; if the user clicks the capture control at time B, the second video segment may be a video segment captured by the electronic device's camera before time B.

[0050] Among them, before the touch operation, the preset storage space is used to store one or more recently recorded video segments. For example, the preset storage space may include the two most recently recorded video segments by the terminal device before the touch operation. For example, before the touch operation, the terminal device records video segment 1, video segment 2, and video segment 3 in chronological order. If the preset storage space is used to store the two most recently recorded video segments, then before the terminal device records video segment 3, the preset storage space may include video segment 1 and video segment 2. When the terminal device starts recording video segment 3, the terminal device may delete video segment 1 (the earliest recorded video segment) in the preset storage space. When the recording of video segment 3 is finished, the preset storage space may include video segment 2 and video segment 3.

[0051] Optionally, the duration of the multiple video segments stored in the preset storage space may be any duration, which is not limited in this embodiment of the present disclosure.

[0052] Among them, the electronic device can obtain at least one second video segment in the preset storage space based on the following feasible implementation method: determine a third video segment among multiple video segments in the preset storage space, and obtain the length of the third video segment, and obtain at least one second video segment in the preset storage space according to the length of the third video segment.

[0053] The third video segment may be the last video segment recorded before the touch operation. For example, if the electronic device records video segments 1, 2, and 3 before the touch operation, and the user touches the capture control after the electronic device finishes recording video segment 3, the electronic device may determine that the third video segment is video segment 3.

[0054] The process of obtaining the third video segment is described below with reference to FIG. 4 .

[0055] Figure 4 is a schematic diagram of obtaining a third video segment according to an embodiment of the present disclosure. Referring to Figure 4 , the video segment includes: video segment 1, video segment 2, and video segment 3 recorded by an electronic device (not shown in Figure 4 ). If the user clicks the capture control after recording video segment 2, the electronic device may determine video segment 2 as the third video segment, and may determine video segment 3 as the first video segment.

[0056] Optionally, the duration of multiple video segments other than the third video segment in the preset storage space can be the second duration, and the duration of the third video segment can be less than or equal to the second duration. For example, the electronic device can store video segment 1 and video segment 2 in the preset storage space, so the duration of video segment 1 and video segment 2 can both be the second duration. For example, in the embodiment shown in Figure 4, video segment 2 is the third video segment, the duration of video segment 1 can be the second duration, the duration of video segment 3 (the first video segment) can be the first duration, and the duration of video segment 2 can be the second duration, or it can be less than the second duration. For example, in the embodiment shown in Figure 4, the second duration of the video segment recorded by the electronic device is 1.5 seconds. When the electronic device finishes recording video segment 1, if the electronic device continues to record for 0.5 seconds and the user clicks the shooting control, the electronic device can determine that the duration of video segment 2 is 0.5 seconds.

[0057] It should be noted that in the embodiment of the present disclosure, the first duration and the second duration can be any duration, and the embodiment of the present disclosure does not limit this. Moreover, the first duration can be equal to the second duration, or the first duration can be different from the second duration, and the embodiment of the present disclosure does not limit this.

[0058] Optionally, the electronic device may determine the duration of the third video segment based on any feasible implementation method, which is not limited in the embodiment of the present disclosure.

[0059] The electronic device obtains at least one second video segment from the preset storage space according to the duration of the third video segment, in the following two situations:

[0060] Case 1: the duration of the third video segment is equal to the first threshold.

[0061] If the duration of the third video segment is equal to the first threshold, the electronic device may determine the third video segment as the second video segment. The first threshold may be the duration of the recorded video segment in the preset storage space. For example, the first threshold may be the second duration in the embodiment of the present disclosure. If the electronic device determines that the duration of each video segment in the preset storage space is 1.5 seconds, the first threshold may be 1.5 seconds. When the duration of the third video segment is equal to 1.5 seconds, it means that when the user clicks the shooting control, the previous video segment has already been recorded for 1.5 seconds. Therefore, the electronic device may determine this video segment as the second video segment.

[0062] For example, in the embodiment shown in Figure 4, the second duration can be 1.5 seconds. When the user clicks the shooting control, the electronic device can determine that the third video segment is video segment 2. If video segment 2 has been recorded for 1.5 seconds, the electronic device can determine that video segment 2 is the second video segment.

[0063] In this way, the electronic device can accurately and quickly determine the second video segment based on the duration of the third video segment, without having to crop or splice multiple video segments in the preset storage space, thereby improving the efficiency of determining the second video segment.

[0064] Case 2: The duration of the third video segment is less than the first threshold.

[0065] If the duration of the third video segment is less than the first threshold, the third video segment and the video segment recorded before the third video segment are determined as the second video segment. For example, the first threshold may be the second duration in the embodiment of the present disclosure, where the first threshold may be 1.5 seconds. If the duration of the third video segment is less than 1.5 seconds, it means that the previous video segment had not yet been recorded to 1.5 seconds when the user clicked the capture control. Therefore, the duration of the third video segment is insufficient, and the electronic device may determine the third video segment and the video segment before the third video segment as the second video segment.

[0066] The process of determining the second video segment in this case will be described below with reference to FIG. 5 .

[0067] Figure 5 is a schematic diagram of a process for determining a second video segment provided by an embodiment of the present disclosure. Please refer to Figure 5, which includes: video segment 1 and video segment 2 stored in a preset storage space by an electronic device (not shown in Figure 5). Among them, the duration of video segment 1 is 1.5 seconds, and the duration of video segment 2 is 0.7 seconds. When video segment 2 is recorded to 0.7 seconds, the user clicks the shooting control, and the electronic device can determine video segment 2 as the third video segment. Since the duration of video segment 2 is less than 1.5 seconds, the electronic device can determine video segment 1 and video segment 2 as the second video segment. In this way, when the duration of video segment 2 is insufficient, the electronic device can crop and splice video segment 1 and video segment 2, and then obtain the video segment before shooting in the live photo, thereby improving the accuracy and flexibility of obtaining live photos and saving system memory.

[0068] S203: Generate a video according to the first video segment and at least one second video segment.

[0069] The video may be a video in a live image. For example, the video may be a video before the user presses the capture control and a video after the user presses the capture control.

[0070] The electronic device generates a video based on the first video segment and at least one second video segment in the following two situations:

[0071] Case 1: The number of the second video segments is 1.

[0072] If the number of second video segments is 1, the first video segment and the second video segment are spliced ​​together to obtain a video. For example, if the number of second video segments is 1, it means that the video segment before the touch operation has been recorded (i.e., the recording duration has reached the second duration). Therefore, the electronic device can splice the first video segment and the second video segment together to obtain the video in the live image.

[0073] The process of generating a video in this case will be described below with reference to FIG6 .

[0074] Figure 6 is a schematic diagram of a video generation method provided by an embodiment of the present disclosure. Referring to Figure 6 , the electronic device (not shown in Figure 6 ) stores video segments 1, 2, and 3 in a preset storage space. Video segment 1 lasts 1.5 seconds, video segment 2 lasts 1.5 seconds, and video segment 3 lasts 2 seconds.

[0075] As shown in Figure 6, when the recording of video segment 2 ends, the user clicks the capture control, and the electronic device can continue recording a 2-second video segment 3. Since the duration of video segment 2 is the same as the duration of video segment 1, the electronic device can determine video segment 2 as the second video segment and video segment 3 as the first video segment.

[0076] As shown in Figure 6, since the number of second video segments is 1, the electronic device can splice video segments 2 and 3 in the order of their recording time to obtain a video of the live image. The live image video can include video segments 2 and 3, and the duration of the video in the live image is 3.5 seconds. In this case, the electronic device can quickly obtain the live image video, improving the efficiency of generating the live image.

[0077] Case 2: The number of second video segments is greater than one.

[0078] If the number of second video segments is greater than one, a fourth video segment is extracted from the plurality of second video segments and the fourth video segment is concatenated with the first video segment to generate a video. The fourth video segment may have the second duration or any duration, which is not limited in this embodiment.

[0079] For example, if the number of second video segments is greater than 1, it means that the video segment recorded by the electronic device before the touch operation is insufficient in length. Therefore, the electronic device can intercept a fourth video segment of the second length from multiple second video segments, and splice the fourth video segment with the first video segment to obtain a video of the live image.

[0080] The process of generating a video in this case is described below with reference to FIG7 .

[0081] Figure 7 is a schematic diagram of another video generation method provided by an embodiment of the present disclosure. Referring to Figure 7 , the electronic device (not shown in Figure 7 ) stores video segments 1, 2, and 3 in a preset storage space. Video segment 1 lasts 1.5 seconds, video segment 2 lasts 1 second, and video segment 3 lasts 2 seconds.

[0082] As shown in Figure 7, when video segment 2 reaches 1 second, the user clicks the capture control, causing the electronic device to stop recording video segment 2 and record a 2-second video segment 3. Because the duration of video segment 2 is shorter than the duration of video segment 1, the electronic device can determine video segments 1 and 2 as the second video segment, and the electronic device can determine video segment 3 as the first video segment.

[0083] Please refer to Figure 7. Since the number of second video segments is 2, the electronic device can capture a 1.5-second video segment 4 from video segments 1 and 2, wherein the electronic device can splice the last 0.5-second video segment of video segment 1 with video segment 2 to obtain video segment 4.

[0084] Referring to Figure 7 , the electronic device can splice video segments 4 and 3 in chronological order to obtain a video of the live image. This live image video can include video segments 4 and 3, and the duration of the live image video can be 3.5 seconds. In this case, the electronic device can accurately extract a sufficiently long video segment from the multiple second video segments, thereby accurately determining the video in the live image, thereby improving the accuracy of the video.

[0085] It should be noted that in the embodiment of the present disclosure, the length of the generated video can be any length and the embodiment of the present disclosure does not limit this. The length of the video can determine the length of the first video segment and the length of the fourth video segment. For example, each video segment in the preset storage space is 0.5 seconds. If the user needs 2 seconds of video before pressing the shooting control, the electronic device can obtain at least 4 video segments before pressing the shooting control. If the user needs 4 seconds of video after pressing the shooting control, the electronic device can continue to record 4 seconds of video after the user presses the shooting control.

[0086] Optionally, after the electronic device generates a video based on the first video segment and at least one second video segment, the video processing method further includes acquiring a captured image associated with the touch operation, and determining a live image based on the captured image and the video. For example, after the electronic device acquires the video, the electronic device may use the captured image as the cover of the video, thereby obtaining a live image.

[0087] It should be noted that the electronic device may also use any image in the video as the cover of the live image, which is not limited in the embodiment of the present disclosure.

[0088] The disclosed embodiment provides a video processing method, which records a first video segment in response to a touch operation on a shooting control in a shooting page, and determines a third video segment from a plurality of video segments in a preset storage space. The electronic device can obtain the duration of the third video segment. If the duration of the third video segment is equal to a first threshold, the third video segment is determined as the second video segment. If the duration of the third video segment is less than the first threshold, the third video segment and the video segment recorded before the third video segment are determined as the second video segment. The electronic device can generate a video based on the first video segment and at least one second video segment. In this way, since the electronic device adopts a segmented recording method for video segments, and before the touch operation, the preset storage space can only store one or more recently recorded video segments, it can avoid memory overflow caused by opening the shooting page for a long time. Moreover, after the electronic device records a video segment, it can encode the video segment without storing the original picture data in the preset storage space, thereby saving memory resources of the electronic device.

[0089] Based on the embodiment shown in Figure 2, before the electronic device obtains at least one second video in the preset storage space, the above-mentioned video processing method also includes a method for storing multiple video segments in the preset storage space. Below, in combination with Figure 8, the method for storing multiple video segments in the preset storage space is explained.

[0090] FIG8 is a schematic diagram of a method for storing multiple video segments provided by an embodiment of the present disclosure. Referring to FIG8 , the method process includes:

[0091] S801. Obtain the remaining memory of the electronic device.

[0092] It should be noted that the electronic device can obtain the remaining memory of the electronic device based on any feasible implementation method (for example, by obtaining device storage information, etc.), and the embodiments of the present disclosure are not limited to this.

[0093] S802: Determine the duration of the video segment stored in the preset storage space according to the remaining memory of the electronic device.

[0094] Optionally, the electronic device may determine the duration of the video segment stored in the preset storage space based on a preset correspondence. The preset correspondence may include at least one memory and the duration corresponding to each memory. For example, the preset correspondence may be as shown in Table 1:

[0095] Table 1

[0096] It should be noted that Table 1 is only an example of the preset corresponding relationship and is not intended to limit the preset corresponding relationship.

[0097] For example, if the remaining memory of the electronic device is memory 1, the electronic device can determine that the duration of the video segment stored in the preset storage space is duration 1; if the remaining memory of the electronic device is memory 2, the electronic device can determine that the duration of the video segment stored in the preset storage space is duration 2; if the remaining memory of the electronic device is memory 3, the electronic device can determine that the duration of the video segment stored in the preset storage space is duration 3.

[0098] Optionally, the remaining memory of the electronic device is proportional to the duration of the video segments stored in the preset storage space. For example, the larger the remaining memory of the electronic device, the longer the video segments stored in the preset storage space. This allows for efficient use of the electronic device's memory, improving not only the flexibility of video segment storage but also memory utilization.

[0099] S803: Record a video segment according to the duration of the video segment stored in the preset storage space.

[0100] For example, if the duration of the video segment stored in the preset storage space is 0.5 seconds, the electronic device can record a 0.5-second video segment; if the duration of the video segment stored in the preset storage space is 1.5 seconds, the electronic device can record a 1.5-second video segment.

[0101] S804: Store the video segment in a preset storage space.

[0102] Optionally, the electronic device may store multiple video segments in a preset storage space based on the following feasible implementation method: obtaining the number of video segments stored in the preset storage space, and if the number of stored video segments is greater than or equal to a second threshold, deleting the earliest recorded video segment in the preset storage space.

[0103] It should be noted that the second threshold may be the number of latest video segments stored in the preset storage space, or may be any set value, which is not limited in the embodiment of the present disclosure.

[0104] Before a user presses the capture button, the electronic device can record and store multiple video segments. If there are many video segments stored in the preset storage space, the electronic device can delete the oldest recorded video segment, thereby saving the preset storage space. For example, if the electronic device has already recorded two 1.5-second video segments before the user presses the capture button, when the electronic device begins recording the third video segment, the electronic device can delete the first 1.5-second video segment from the preset storage space, thereby saving memory.

[0105] 9 , the process of storing multiple video segments in an electronic device will be described below.

[0106] FIG9 is a schematic diagram of an electronic device storing multiple video segments according to an embodiment of the present disclosure. Referring to FIG9 , it includes a preset storage space. The preset storage space may include video segment 1 and video segment 2. Both video segment 1 and video segment 2 are video segments recorded by the electronic device (not shown in FIG9 ) before the user presses the capture control. Video segment 1 is 1.5 seconds long, and video segment 2 is 1.5 seconds long. Video segment 1 is the video segment to be deleted.

[0107] As shown in Figure 9 , when the electronic device begins recording the next video segment after video segment 2, the electronic device can delete video segment 1. The preset storage space may include video segment 1. When the electronic device begins recording the video segment to be recorded, the electronic device can store the recorded content in the preset storage space.
