[0029] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0030] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0031] The video preview method, video preview device, and electronic device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0032] Referring to FIG1 , the video preview method provided in the embodiment of the present application may include the following steps:

[0033] Step 101: Obtain N frames of target images in a first video, where N is an integer greater than 1.

[0034] Step 102: Display thumbnails corresponding to the N frames of target images on an album interface.

[0035] In some embodiments, the first video may be obtained by shooting with a camera, or the first video may be received through network transmission. For ease of explanation, the embodiments of the present application generally use the example of obtaining the first video by shooting with a camera as an example, which does not constitute a specific limitation here.

[0036] In one embodiment, the N frames of target images may be acquired during the process of acquiring the first video. For example, during the process of shooting the first video, a frame of image is taken at intervals of a certain length as the target image.

[0037] In another embodiment, a first video may be acquired first, and then N frames of target images may be extracted from the first video.

[0038] It should be noted that the video is composed of a large number of pictures arranged in chronological order, and each picture has its own corresponding frame time or arrangement position. At this time, the target image can be a picture arranged at any position in the first video, or a picture in the first video corresponding to any frame time.

[0039] As shown in FIG. 2 , in the related art, only one thumbnail 21 of a video is displayed in the album interface, such as a thumbnail of the first frame image in the video.

[0040] In the embodiment of the present application, at least two frames of images are extracted from the first video as target images, and thumbnails of all target images are displayed in the album interface. At this time, as shown in Figure 3, one video will correspond to at least two thumbnails 32, and each thumbnail 32 corresponds to different image content in the video. Compared with the related art that only displays a thumbnail of an image frame in a video, it is possible to display thumbnails of more images in the same video, which is beneficial for users to preview more detailed image content in the video based on the thumbnail.

[0041] Optionally, thumbnails of at least two frames of target images extracted from the same video can be displayed in the album interface according to the arrangement order of the at least two frames of target images, that is, the arrangement order of the thumbnails displayed in the album interface is consistent with the arrangement order of the corresponding target images in the first video.

[0042] It is worth mentioning that the above-mentioned album interface can be the interface of an album application, and the album application can include a large number of photos and videos. Based on the embodiment of the present application, the thumbnails of the photos and the thumbnails of the videos can be displayed together in the album interface for the user to select. Among them, the thumbnails of the videos are thumbnails of the target images extracted from the video, and a video can have at least two thumbnails.

[0043] In a first embodiment, a method of acquiring N frames of target images in the first video may be: extracting N frames of target images from the first video according to a preset period.

[0044] Optionally, the preset period can be a preset time period. For example, assuming that the length of the first video is 100s, a frame of target image is taken out every 10s, then the images at the 11 time points of 0s, 10s, 20s, 30s, 40s, 50s, 60s, 70s, 80s, 90s, and 100s are selected as target images.

[0045] Optionally, the preset period can be a preset frame number period, for example: assuming that the first video contains 10 frames of images, one frame of image is extracted from the first video as the target image every 3 frames, then the 1st frame, 4th frame, 7th frame and 10th frame are selected as the target images.

[0046] Optionally, the preset period may be factory preset for the electronic device that executes the video preview method provided in the embodiment of the present application, or may be set by the user, or may be positively correlated with the length of the video, and is not specifically limited here.

[0047] In this embodiment, based on the preset period, the longer the first video is, the larger the value of N is.

[0048] In a second embodiment, a method of obtaining N frames of target images in the first video may be: extracting N frames of target images from the first video based on a preset value, where N is the preset value.

[0049] Optionally, the above-mentioned preset value may be the factory preset value of N of the electronic device that executes the video preview method provided in the embodiment of the present application, or the value of N set by the user, or the value of N is positively correlated with the video length, which is not specifically limited here.

[0050] Optionally, after the value of N is determined, N frames of images may be uniformly extracted from the first video as target images.

[0051] In this embodiment, the value of N can be preset so that the same number of target images can be extracted for videos of different lengths. In this way, a fixed number of target images can be extracted from each video, such as 5 frames of target images per video.

[0052] In a third embodiment, obtaining N frames of target images in the first video includes:

[0053] When the difference between the feature information of the first image and the feature information of the second image is greater than or equal to a first threshold, the second image is determined as the target image, wherein the first image and the second image are two adjacent frames of images in the first video, and the first image is arranged before the second image.

[0054] Optionally, the above-mentioned feature information can be feature point information. In this case, the difference between the feature information of the first image and the feature information of the second image is greater than or equal to the first threshold value, or the difference between the feature point information of two adjacent frames of images in the first video can be greater than or equal to the first threshold value, for example: the first image captures a person and the second image captures a scene.

[0055] In some implementations, feature information of each frame of the first video may be extracted, and feature information of two adjacent frames of the image may be compared for difference.

[0056] Among them, the first threshold can be a pre-set value or a value set by the user. For example, assuming that the first threshold is 50%, when the change in the feature points of two adjacent frames of images is greater than or equal to 50%, the latter frame of the two adjacent frames of images is used as the target image.

[0057] In some embodiments, feature information of any two adjacent frames of images in the first video can be compared to determine whether the feature difference between the two adjacent frames is large. If so, it is determined that the content captured by the latter frame of the two adjacent frames has changed. At this time, the latter frame of image is used as the target image, and a more representative target image can be selected from the first video.

[0058] For example: the album interface shown in Figure 3 displays thumbnails of target images extracted using the first or second implementation method; the album interface shown in Figure 4 displays thumbnails of target images extracted using the third implementation method. Comparing Figures 3 and 4, it can be seen that the thumbnail selected in Figure 3 may not be able to fully reflect the content of the first video, or may omit part of the content of the first video, or repeatedly display the same similar scene redundantly. Compared with Figure 4, the image 41 containing the "ribbon" is omitted in the album interface as shown in Figure 3; and the difference between the target images corresponding to any two adjacent thumbnails in Figure 4 is relatively large, so that the content of the first video can be displayed more comprehensively and completely.

[0059] In this embodiment, the probability of extracting target images with similar or repeated content can be reduced, and thus, on the basis of reducing the number of target images, the extracted target images can specifically reflect the changes in the image content in the first video.

[0060] In a fourth embodiment, obtaining N frames of target images in the first video includes:

[0061] In a case where a first object is acquired from the third image and a second object acquired from the fourth image is different from the first object, determining the third image as the target image;

[0062] The fourth image is each frame of image arranged before the third image in the first video.

[0063] Among them, the number of fourth images can be one or more, for example: when the fourth image is the second frame image in the first video, at this time, the third image includes the first frame image in the first video; when the fourth image is the Mth frame image in the first video, at this time, the third image includes the first frame to the (M-1)th frame image in the first video, where M is an integer greater than 1.

[0064] Of course, the third image can also be the first frame image in the first video, and there is no fourth image. At this time, there must be no second object matching the object in the first frame image, so the first frame image in the first video is used as the target image.

[0065] In some implementations, the first object and the second object may be people.

[0066] Optionally, attribute information of objects in each frame of the first video may be obtained. For example, the attribute information of each object may be identification information of each person, such as distinguishing person A, person B, etc. through attribute information.

[0067] Optionally, the second object obtained from the fourth image is different from the first object, and the second attribute information of the second object may not match the first attribute information of the first object, such as a person appears in the third image that has not appeared in the fourth image.

[0068] In other implementations, the first object and the second object may be scenes.

[0069] Optionally, attribute information of objects in each frame of the first video may be obtained. For example, the attribute information of each object may be identification information of each scene, such as distinguishing scene C from scene D through attribute information.

[0070] Optionally, the second object obtained from the fourth image is different from the first object, and a scene that has not appeared in the fourth image may appear in the third image. For example, the third image is an image of an indoor scene, and the fourth image before the third image is an image of an outdoor scene, then the third image is determined as the target image.

[0071] For example, the person in each frame of the first video is identified frame by frame, and the first frame of the first video is determined as the target image. Then, the person in the second frame is compared with the person in the first frame. If the person in the second frame is the same as the person in the first frame, the second frame is not determined as the target image. If the person in the second frame is at least partially different from the person in the first frame, the second frame is determined as the target image. Finally, the same process is repeated until the Qth frame in the first video is determined to be the target image, where Q is the total number of frames in the first video.

[0072] In this embodiment, objects in each frame of the first video can be identified, and the image containing the first appearance of each object can be used as the target image, so that the target image can display different objects in a targeted manner, thereby fully reflecting the different objects in the video and avoiding redundant display of the same objects through thumbnails in the album interface.

[0073] It should be noted that at least two of the above four implementations for extracting N frames of target images from the first video can be combined, for example: the image extracted by the third implementation and the image extracted by the fourth implementation are used as target images, which is not specifically limited here.

[0074] In some implementations, the user can also operate on the thumbnails in the album interface to edit the thumbnails, such as deleting thumbnails, updating thumbnails, adding thumbnails, etc.

[0075] In a first embodiment, the method further comprises:

[0076] receiving a first input of a first thumbnail, where the first thumbnail is a thumbnail of a first target image in the N frames of target images;

[0077] In response to the first input, the first video is played starting from the first target image.

[0078] In one embodiment, the method further comprises:

[0079] A first identifier is displayed on the thumbnail, where the first identifier indicates that the thumbnail is a thumbnail of a video.

[0080] For example, as shown in Figure 3, there is a first mark 31 above each video thumbnail 32 in the album interface, and the first mark 31 can be a video mark. In this way, through the first mark 31, it is possible to distinguish whether the thumbnail in the album interface is a photo thumbnail or a video thumbnail.

[0081] Optionally, the first input may be a touch input to the first identifier in the first thumbnail, such as clicking the first identifier in the first thumbnail.

[0082] In this embodiment, by performing a first input on the first thumbnail, the first video can be triggered to start playing from the first target image corresponding to the first thumbnail. That is, by selecting the thumbnail targeted by the first input, the starting position of the playback of the first video can be adjusted.

[0083] In a second embodiment, the method further comprises:

[0084] receiving a second input of a second thumbnail, wherein the thumbnails of the N frames of target images include the second thumbnail;

[0085] In response to the second input, the second thumbnail is deleted from the album interface.

[0086] Among them, the second input can be any operation for deleting the second thumbnail, for example: as shown in Figure 5, the second input is a touch input of two fingers together. Specifically, as shown in Figure 5, the user can use two fingers to touch the two thumbnails in the album interface respectively. When the two fingers are together, one of the two thumbnails can be deleted, such as deleting the right one of the two thumbnails, or deleting the lower one of the two thumbnails. There is no specific limitation here.

[0087] It should be noted that, while deleting the second thumbnail, a frame of target image corresponding to the second thumbnail may also be deleted from the target image extracted from the first video.

[0088] In this embodiment, when too many target images are extracted, thumbnails corresponding to some of the target images may be deleted from the album interface through the second input.

[0089] In a third embodiment, the method further comprises:

[0090] receiving a third input of a third thumbnail, wherein the third thumbnail is a thumbnail of a second target image in the N frames of target images;

[0091] During the execution of the third input, the third thumbnail and thumbnails of each frame of the first video that is arranged after the second target image are displayed frame by frame in the first area;

[0092] When it is detected that the third input is finished, the third thumbnail is modified into a thumbnail of a third target image, where the thumbnail of the third target image is the thumbnail displayed in the first area at the end of the third input.

[0093] In some implementations, the first area may be the area within the album interface where the third thumbnail is located.

[0094] Among them, the third input is an input with a certain duration, for example: a long press operation. At this time, the execution period of the third input is the period of long pressing the third thumbnail, and the moment when the third input execution ends is the moment when the long press of the third thumbnail ends, that is, the moment when the touch part leaves the third thumbnail.

[0095] It should be noted that the third thumbnail and the thumbnail of each frame of the first video that follows the second target image are displayed frame by frame in the first area. This is different from the "playing the first video starting from the first target image in response to the first input" in the first embodiment. Specifically, the first embodiment can open the video playback interface to play the first video starting from the first target image; in this embodiment, the thumbnail is only switched to be displayed within the original display area of ​​the third thumbnail. That is, at this time, the displayed interface is still the album interface, and there is no need to open the video playback interface.

[0096] For example, as shown in FIG6 , when the user's finger long presses the first area 61, the thumbnail displayed in the first area 61 starts to switch backward frame by frame. When the user's finger leaves the first area 61, the thumbnail currently displayed in the first area 61 is used as the thumbnail of the target image. In this way, the thumbnail in the first area 61 is updated, and the target image is updated.

[0097] In this embodiment, the thumbnails in the first area can be updated by performing a third input on the first area.

[0098] In some embodiments, the method further comprises:

[0099] A second identifier is displayed on the thumbnail, where the second identifier is used to uniquely identify the first video in the target album corresponding to the album interface.

[0100] In one embodiment, the second identifier may be a video identifier, such as "Video 1", "Video 2", etc. In this case, the second identifier may be used to distinguish the videos corresponding to the thumbnails in the album interface.

[0101] In another embodiment, the second identifier can be the identifier of the target image, such as "Video 1-1" indicates the first target image in video 1, and "Video 1-2" indicates the second target image in video 1. In this case, the second identifier can be used to distinguish the target images corresponding to each thumbnail in the album interface.

[0102] In this embodiment, the second identifier can be used to distinguish the videos corresponding to the thumbnails in the album interface. In this way, when the target album corresponding to the album interface contains at least two videos, based on the different second identifiers corresponding to different videos, the thumbnails corresponding to different videos can be displayed separately in the album interface.

[0103] It's worth noting that when selecting a video from the album interface, selecting a thumbnail will select the video corresponding to that thumbnail. For example, when selecting a video to send from the album interface, if the same video has N thumbnails, the user only needs to select any of the N thumbnails, such as clicking on a thumbnail, to select that video as the video to be sent.

[0104] As an optional implementation, the method further includes:

[0105] Determine the target sub-album according to the image features contained in each photo or each frame of the target image in the target album;

[0106] Among them, the target album includes the album corresponding to the album interface, the target sub-album includes at least one photo or a fourth target image, the N frames of target images include the fourth target image, and the photos or fourth target images in the target sub-album have the same image features.

[0107] The aforementioned image features may include at least one of facial features, shooting scene features, and other features. The presence of the same image features in the photos or fourth target images in the target sub-album can be understood as grouping photos and videos containing image content of the same person or scene into sub-albums associated with that person. For ease of explanation, the present application uses facial features as an example of an image feature, which is not intended to be a specific limitation.

[0108] Optionally, in one embodiment, face recognition or scene recognition can be performed on the photos or target images to classify the faces or scenes contained in each photo or each frame of the target image, and the photos or target images containing the same face or scene can be grouped into the same sub-album. In this way, when the sub-album interface is displayed, a thumbnail corresponding to each photo or target image in the sub-album can be displayed.

[0109] It should be noted that when at least one target image frame of a video is classified in a certain sub-album, it means that the video is classified in the sub-album.

[0110] It is worth noting that in related technologies, photos are only classified based on facial recognition information and shooting location information, while in the implementation of the present application, photos and videos can be classified based on image features.

[0111] In addition, given that different target images in the same video may contain different image features, different target images in the same video may be classified into different sub-albums.

[0112] For example: Suppose a video includes two frames of target images, where the first frame of target image contains the face of person A and the second frame of target image contains the face of person B. Then, by performing facial image recognition on these two frames of target images, it can be determined that the first frame of target image contains the face of person A, and the video is thus classified in the sub-album corresponding to person A. It can be determined that the second frame of target image contains the face of person B, and the video is also classified in the sub-album corresponding to person B.

[0113] It should be noted that when a sub-album interface is displayed, the thumbnails displayed in the sub-album interface all have image features corresponding to the sub-album.

[0114] For example: Suppose a video includes two frames of target images, where the first frame of target image contains the face of person A and the second frame of target image contains the face of person B. When the sub-album interface corresponding to person A is displayed, the interface contains a thumbnail corresponding to the first frame of target image; when the sub-album interface corresponding to person B is displayed, the interface contains a thumbnail corresponding to the second frame of target image.

[0115] In order to facilitate the description of the video preview method provided in the embodiments of the present application, the video preview method provided in the present application is illustrated by taking the following two embodiments as examples.

[0116] Example 1

[0117] As shown in FIG7 , the video preview method in this embodiment may include the following steps:

[0118] Step 701: Shoot a first video.

[0119] Step 702: Display thumbnails of N frames of target images in the album interface.

[0120] In this step, the first implementation or the second implementation for extracting N frames of target images from the first video in the method embodiment shown in FIG1 can be adopted to achieve the extraction of N frames of target images in the first video.

[0121] Step 703: The user searches for the desired video in the album interface based on the N thumbnails.

[0122] Step 704: The user clicks on the selected thumbnail.

[0123] Step 705: Play the video.

[0124] In this embodiment, by increasing the number of target images corresponding to thumbnails, the video content displayed in the album interface can be improved, thereby facilitating users to select videos that meet their needs.

[0125] Example 2

[0126] As shown in FIG8 , the video preview method in this embodiment may include the following steps:

[0127] Step 801: Shoot a first video.

[0128] Step 802: Display thumbnails of N frames of target images in the album interface.

[0129] In this step, the third implementation and / or the fourth implementation for extracting N frames of target images from the first video in the method embodiment shown in Figure 1 can be adopted to achieve the extraction of N frames of target images in the first video.

[0130] Step 803: The user searches for the desired video in the album interface based on N thumbnails.

[0131] Step 804: The user clicks on the selected thumbnail.

[0132] Step 805: Categorize the photos and videos together.

[0133] In this step, reference may be made to the method embodiment shown in FIG1 : determining the explanation of the target sub-album according to the image features contained in each photo or each frame of the target image in the target album, which will not be repeated here.

[0134] In this embodiment, the third implementation and / or the fourth implementation for extracting N frames of target images from the first video in the method embodiment shown in Figure 1 are adopted to extract N frames of target images in the first video, and more thumbnails can be used to display the content of the first video more comprehensively; in addition, the function of classifying photos and videos together is also realized.
