[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0028] The embodiment of the present application provides a method for cleaning up media items, which can be applied to electronic devices. The electronic devices can be smart phones, tablet computers, gaming devices, AR (Augmented Reality) devices, data storage devices, video playback devices, laptop computers, desktop computing devices, etc.

[0029] refer to Figure 1 , Figure 1 Schematic diagram of the application scenario of the media item cleaning method of the embodiment of the present application. The media item cleaning method is applied to an electronic device, in which a large number of media items are stored, for example, multiple media items such as media item a to media item i are stored. Among them, media item a to media item i may include one or more of photos, QR codes, screenshots, emoticons, dynamic pictures, and videos. In order to save the storage space of the electronic device, it is necessary to clean up the media items stored in the electronic device regularly or irregularly.

[0030] In an example of practical application, the media item cleaning method can be integrated into a media item cleaning tool (SDK), or some implementation steps of the media item cleaning method can be integrated into a media item cleaning tool (SDK). The media item cleaning tool (SDK) can be, for example, a mobile phone manager, or a module in a mobile phone manager. After a user uses an electronic device for a long time, more and more media items will be stored in the electronic device, such as photos, QR codes, screenshots, emoticons, dynamic pictures, videos, etc. In order to reduce the storage space occupied by a large number of media items, a media item cleaning tool (SDK) can be used to clean up media items.

[0031] refer to Figure 2 , Figure 2 This is a first flow chart of a media item cleaning method according to an embodiment of the present application. The media item cleaning method includes the following steps 110 to 140:

[0032] 110 , scan at least one media item to be scanned to obtain media item information of the media item.

[0033] When cleaning up media items, firstly, the media items to be scanned need to be scanned. The media items to be scanned may be one or more. The media items to be scanned may include, for example, photos, QR codes, screenshots, emoticons, dynamic pictures, videos, etc.

[0034] The electronic device can obtain the media item information of the media item by scanning the media item. The media item information is used to indicate the type of the media item. The type of the media item can reflect the cleaning tendency of the user, and the type of the media item can be set based on experience. Therefore, the type of the media item can be used to indicate whether the media item is cleanable.

[0035] For example, the types of media items may include landscape photos, portrait photos, ID photos, QR codes, game screenshots, blurred images, emoticons, dynamic images, short videos (e.g., videos with a duration of less than 1 minute), long videos (e.g., videos with a duration of more than 1 minute), etc. According to experience, in the cleaning tendency of users, media items such as QR codes, game screenshots, blurred images, emoticons, dynamic images, and short videos are usually cleaned up by users; while media items such as landscape photos, portrait photos, ID photos, and long videos are not usually cleaned up by users.

[0036] In practical applications, electronic devices may store a large number of media items, such as a large number of photos, emoticons, videos, and the like. Among these media items, there may be some similar content, for example, there may be multiple photos that are similar, or multiple emoticons that are similar. When processing these media items, such as cleaning them, in order to reduce the occupation of cache space by a large number of media items, one of the multiple similar media items may be set as a root media item, and the remaining similar media items may be set to point to the root media item.

[0037] For example, the photos stored in the electronic device include 3 groups of similar photos, each group of similar photos includes multiple photos. Among them, similar photo group A is landscape photos, photo group B is person photos, and photo group C is ID photos. The electronic device can set one photo in photo group A as root media item A, and set the remaining photos in photo group A to point to root media item A; set one photo in photo group B as root media item B, and set the remaining photos in photo group B to point to root media item B; set one photo in photo group C as root media item C, and set the remaining photos in photo group C to point to root media item C.

[0038] In some embodiments, when the electronic device scans at least one media item to be scanned and obtains media item information of the media item, the electronic device may perform the following steps:

[0039] Determining whether at least one media item to be scanned has a corresponding root media item;

[0040] If the media item has a corresponding root media item, then obtaining the media item information of the root media item, and using the media item information of the root media item as the media item information of the media item;

[0041] If the media item does not have a corresponding root media item, the media item is scanned to obtain media item information of the media item.

[0042] For each media item to be scanned, the electronic device may first determine whether there is a corresponding root media item. If there is a corresponding root media item, the media item information of the root media item is obtained, for example, the root media item may be scanned to obtain the media item information of the root media item, and the media item information of the root media item is used as the media item information of the media item. If there is no corresponding root media item, the media item is scanned to obtain the media item information of the media item.

[0043] 120, adding media item information to the cache.

[0044] After the electronic device scans the media item and obtains the media item information, the media item information can be added to the cache. It can be understood that the electronic device can quickly read the media item information loaded in the cache at any time.

[0045] In actual applications, the media items to be scanned may include multiple media items, for example, hundreds of pictures, emoticons, screenshots, videos, etc. When an electronic device scans a media item, the scanning process may be interrupted due to various reasons. If the scanned media item information is not cached in time, the scanning process needs to be re-scanned after the interruption, resulting in a waste of time. If caching is performed once each media item is scanned, system resources will be frequently called to write to the cache, resulting in a waste of system resources.

[0046] Therefore, in an embodiment of the present application, the media item information obtained by scanning multiple media items can be added to the cache in batches, which can not only cache the media item information in a timely manner to avoid wasting time due to interruptions in the scanning process, but also avoid frequently calling system resources to write to the cache, thereby saving system resources.

[0047] In practical applications, media item information can be added to the cache in batches in a variety of ways.

[0048] In an application example, the media item information may be cached in batches according to the data size. Specifically, a preset data size may be set, and the preset data size is a data size, such as 3MB, 5MB, 10MB, etc. When scanning multiple media items, when the data size of the scanned media item information reaches the preset data size, the scanned media item information is added to the cache as a batch.

[0049] refer to Figure 3 , Figure 3 This is a first schematic diagram of adding media item information to the cache in batches in an embodiment of the present application. For example, after scanning media item a, media item b, and media item c, the data volume of the media item information obtained reaches a preset data volume, and the scanned media item information is added to the cache as a batch; after scanning media item d, media item e, and media item f, the data volume of the media item information obtained reaches a preset data volume, and the scanned media item information is added to the cache as a batch; and this process continues until the scanning of the multiple media items is completed.

[0050] In addition, it is understandable that if the number of media items is small, or after multiple batches of media item information have been cached, the number of remaining media items is small, then the data volume of the scanned media item information may not reach the preset data volume, and the media item information also needs to be cached. Therefore, when the multiple media items have been scanned and the data volume of the scanned media item information has not reached the preset data volume, the scanned media item information can also be added to the cache as a batch. Therefore, no matter how many media items are to be scanned, the scanning of all media items can be completed and the media item information can be cached.

[0051] In another application example, batch caching can be performed according to the scanning duration. Specifically, a preset duration can be set, such as 3 seconds, 5 seconds, 10 seconds, etc. When scanning multiple media items, when the scanning duration reaches the preset duration, the scanned media item information is added to the cache as a batch.

[0052] refer to Figure 4 , Figure 4 This is a second schematic diagram of adding media item information to the cache in batches in an embodiment of the present application. For example, after scanning media item a, media item b, and media item c, the scanning time reaches a preset time, and the scanned media item information is added to the cache as a batch; after scanning media item d, media item e, and media item f, the scanning time reaches a preset time, and the scanned media item information is added to the cache as a batch; and this process continues until the scanning of the multiple media items is completed.

[0053] In addition, it is understandable that if the number of media items is small, or after multiple batches of media item information have been cached, the number of remaining media items is small, then the scanning time for scanning the remaining media items may not reach the preset time, and the media item information also needs to be cached. Therefore, when the multiple media items have been scanned and the scanning time has not reached the preset time, the scanned media item information can also be added to the cache as a batch. Therefore, no matter how many media items are to be scanned, the scanning of all media items can be completed and the media item information can be cached.

[0054] In another application example, the media items may be cached in batches according to the number of scanned media items. Specifically, a preset number may be set, such as 3, 5, 10, etc. When scanning multiple media items, when scanning of the preset number of media items among the multiple media items is completed, the scanned media item information is added to the cache as a batch.

[0055] refer to Figure 5 , Figure 5 This is a third schematic diagram of adding media item information to the cache in batches in an embodiment of the present application. For example, the preset number is 3, then after scanning the three media items of media item a, media item b, and media item c, the scanned media item information is added to the cache as a batch; after scanning the three media items of media item d, media item e, and media item f, the scanned media item information is added to the cache as a batch; and this process is continued until the scanning of the multiple media items is completed.

[0056] In addition, it is understandable that if the number of media items is small, or after multiple batches of media item information have been cached, the number of remaining media items is small, then the number of remaining media items may not reach the preset number, and the media item information also needs to be cached. Therefore, when the multiple media items have been scanned and the number of media items corresponding to the scanned media item information has not reached the preset number, the scanned media item information is added to the cache as a batch. Therefore, no matter how many media items are to be scanned, the scanning of all media items can be completed and the media item information can be cached.

[0057] 130 , in response to the media item cleanup request, read the media item information in the cache and classify the media item according to the media item information to obtain a classification result.

[0058] In actual applications, when a user wants to clean up media items stored on an electronic device, the user can start the media item cleaning function, for example, the media item cleaning can be started from a media item cleaning tool (sdk). When the user starts the media item cleaning function, the electronic device generates a media item cleaning request and responds to the media item cleaning request. Specifically, the electronic device can read the media item information in the cache and classify the media items according to the media item information to obtain a classification result.

[0059] For example, media item information may include multiple types such as landscape photos, portrait photos, ID photos, QR codes, game screenshots, blurred images, emoticons, dynamic images, short videos, long videos, etc. Then the electronic device can obtain multiple classification results such as landscape photos, portrait photos, ID photos, QR codes, game screenshots, blurred images, emoticons, dynamic images, short videos, long videos, etc. based on the media item information.

[0060] It should be noted that when the electronic device performs media item cleaning is determined by the time when the user starts the media item cleaning function. The electronic device can continuously scan the media items and add the media item information to the cache. When the electronic device responds to the media item cleaning request, the media item information read from the cache may include many caches, and it is not necessarily scanned and cached only once. Therefore, the media item corresponding to the media item information read from the cache may be different from the media item to be scanned in step 110, and the media item corresponding to the media item information read from the cache at least includes the media item to be scanned in step 110.

[0061] 140 , outputting cleanable media items according to the classification results.

[0062] After the electronic device obtains the classification results, it can output the media items that can be cleaned according to the classification results. For example, the classification results obtained by the electronic device include multiple categories such as landscape photos, portrait photos, ID photos, QR codes, game screenshots, blurred images, emoticons, dynamic pictures, short videos, and long videos. According to the user's usual cleaning habits, it can be considered that media items such as QR codes, game screenshots, blurred images, emoticons, dynamic pictures, and short videos are what the user tends to clean up, so media items such as QR codes, game screenshots, blurred images, emoticons, dynamic pictures, and short videos can be output as cleanable media items. When the user confirms the cleanup, the electronic device can delete these cleanable media items, thereby freeing up the storage space occupied by these media items.

[0063] The media item cleaning method of the embodiment of the present application can scan the media items in advance and add the scanned media item information to the cache before performing the media item cleaning. When performing the media item cleaning, for example, when the user starts the media item cleaning function, the media item information in the cache is directly read to classify and output the cleanable media items. Therefore, when performing the media item cleaning, there is no need to scan the media items again, thereby reducing the time consumed in the media item cleaning and improving the efficiency of the media item cleaning.

[0064] In some embodiments, reference Figure 6 , Figure 6 This is a second flow chart of the media item cleaning method according to an embodiment of the present application. Step 110, scanning at least one media item to be scanned, before obtaining the media item information of the media item, further includes the following steps:

[0065] 150, determining the media item to be scanned.

[0066] In actual applications, the media items to be scanned may be specified by the user, for example, the user may specify the storage path or folder of the media items, or the user may directly select the media items; the media items to be scanned may also be determined by the electronic device itself according to set rules.

[0067] For example, the user may specify which folders need to be cleaned when cleaning up media items, and then each time the electronic device scans media items, it may directly determine the media items in the folders specified by the user as media items to be scanned.

[0068] For another example, in actual applications, media items on an electronic device can be stored in a media library. In one application example, when a new media item is added to the media library, for example, when a user takes a photo or downloads a picture and stores it in the media library, the electronic device can determine the new media item as a media item to be scanned. In another application example, a preset space threshold can be set for the storage space occupied by the media items, for example, the preset space threshold can be 5GB, 30%, etc. When the storage space occupied by the media items in the media library reaches the preset space threshold, the electronic device can determine all media items in the media library as media items to be scanned.

[0069] It should be noted that the above examples are only examples, and in actual applications, other methods may be used to determine the media items to be scanned.

[0070] In some embodiments, continue to refer to Figure 6 Step 110, before scanning at least one media item to be scanned and obtaining media item information of the media item, further comprising the following steps:

[0071] 160, determining whether the media item information of the media item to be scanned is loaded in the cache;

[0072] If the media item information of the media item to be scanned is not loaded in the cache, step 110 is executed to scan the media item to be scanned to obtain the media item information of the media item to be scanned;

[0073] If the media item information of the media item to be scanned is loaded in the cache, step 130 is executed to respond to the media item cleanup request, read the media item information in the cache and classify the media item according to the media item information to obtain a classification result.

[0074] It is understandable that in actual applications, the process of the electronic device scanning the media items and adding the scanned media item information to the cache may be continuous. Before the electronic device scans the media items to be scanned, some media item information may have been loaded into the cache.

[0075] Before scanning the media item to be scanned, the electronic device may first determine whether the media item information of the media item to be scanned is loaded in the cache. If the media item information of the media item to be scanned is not loaded in the cache, step 110 is executed to scan the media item to be scanned to obtain the media item information of the media item to be scanned. If the media item information of the media item to be scanned is loaded in the cache, step 110 is not executed, but step 130 is directly executed.

[0076] Therefore, when the media item information of the media item to be scanned has been loaded into the cache, the media item to be scanned is no longer scanned repeatedly, thereby avoiding repeated scanning of the same media item, which can save system resources and reduce the time consumed for the overall media item scanning.

[0077] It should be noted that, when there are multiple media items to be scanned, the electronic device may perform the determination in step 160 before scanning each media item to be scanned.

[0078] In some embodiments, continue to refer to Figure 6 Step 110, scanning at least one media item to be scanned to obtain media item information of the media item, includes the following steps:

[0079] 111, obtaining a bitmap of a media item to be scanned;

[0080] 112 , input the bitmap into a deep learning model for deep learning to obtain media item information of the media item.

[0081] In practical applications, deep learning models can be integrated into electronic devices. For example, deep learning models can be integrated into media item cleaning tools (sdk), and the deep learning models can also be continuously updated.

[0082] When the electronic device scans the media item to be scanned, it obtains a bitmap of the media item to be scanned. It should be noted that for media items such as dynamic pictures and videos, since dynamic pictures and videos are formed by multiple frames of images, the bitmap of each frame of the image can be obtained as the bitmap of the media item. For example, the bitmap of each frame of a dynamic picture can be obtained as the bitmap of the dynamic picture, and the bitmap of each frame of the video can be obtained as the bitmap of the video. Subsequently, the bitmap is input into a deep learning model for deep learning to obtain media item information of the media item. Therefore, media item information such as the type of the media item can be obtained through the deep learning model.

[0083] It should be noted that, when there are multiple media items to be scanned, the electronic device can obtain a bitmap of each media item when scanning the media item to be scanned, and input the bitmap into the deep learning model for deep learning.

[0084] In specific implementation, the present application is not limited by the execution order of the various steps described. If no conflict occurs, some steps can be performed in other orders or simultaneously.

[0085] As can be seen from the above, the media item cleaning method provided in the embodiment of the present application includes: scanning at least one media item to be scanned to obtain media item information of the media item; adding the media item information to a cache; in response to a media item cleaning request, reading the media item information in the cache and classifying the media item according to the media item information to obtain a classification result; and outputting the cleanable media item according to the classification result. The media item cleaning method of the embodiment of the present application can scan the media item in advance before cleaning the media item and add the scanned media item information to the cache. When cleaning the media item, for example, when the user starts the media item cleaning function, the media item information in the cache is directly read to classify and output the cleanable media item. Therefore, when cleaning the media item, there is no need to scan the media item again, thereby reducing the time consumed in cleaning the media item and improving the efficiency of cleaning the media item.

[0086] The embodiment of the present application also provides a media item cleaning device, which can be integrated in an electronic device. The electronic device can be a smart phone, a tablet computer, a gaming device, an AR (Augmented Reality) device, a data storage device, a video playback device, a laptop computer, a desktop computing device, etc.

[0087] refer to Figure 7 , Figure 7 1 is a schematic diagram of a first structure of a media item cleaning device 200 according to an embodiment of the present application, wherein the media item cleaning device 200 comprises a loading module 210 , a cache module 220 , and a cleaning module 230 .

[0093] Determine whether the media item information of the media item to be scanned is loaded in the cache;

[0094] If the media item information of the media item to be scanned is not loaded in the cache, the media item to be scanned is scanned to obtain the media item information of the media item to be scanned.

[0095] In some embodiments, when scanning at least one media item to be scanned and obtaining media item information of the media item, the loading module 210 is specifically used to:

[0096] Get the bitmap of the media item to be scanned;

[0097] The bitmap is input into a deep learning model for deep learning to obtain media item information of the media item.

[0098] In some embodiments, the cache module 220 can add the media item information obtained by scanning multiple media items to the cache in batches. For example, the cache can be performed in batches according to the data size of the media item information, or according to the scanning time, or according to the number of scanned media items.

[0099] In some embodiments, reference Figure 8 , Figure 8 This is a second structural diagram of the media item cleaning device 200 according to an embodiment of the present application.

[0100] The media item cleaning device 200 further includes a data processing module 240. The data processing module 240 can be used for logic control, for example, it can be used for controlling the loading process of the loading module 210, it can be used for controlling the cache logic of the cache module 220, and it can also be used for controlling the cleaning of media items by the cleaning module 230.

[0101] It can be understood that the specific implementation of each of the above modules can refer to the description of each embodiment of the above media item cleaning method, which will not be repeated here.

[0102] In specific implementation, the above modules can be implemented as independent entities, or can be arbitrarily combined to be implemented as the same entity or several entities.

[0103] As can be seen from the above, the media item cleaning device 200 provided in the embodiment of the present application scans at least one media item to be scanned through the loading module 210 to obtain the media item information of the media item; the cache module 220 adds the media item information to the cache; the cleaning module 230 responds to the media item cleaning request, reads the media item information in the cache and classifies the media item according to the media item information to obtain the classification result, and outputs the media item that can be cleaned according to the classification result. The media item cleaning device 200 of the embodiment of the present application can scan the media item in advance before cleaning the media item and add the scanned media item information to the cache. When cleaning the media item, for example, when the user starts the media item cleaning function, the media item information in the cache is directly read to classify and output the media item that can be cleaned. Therefore, when cleaning the media item, there is no need to scan the media item again, thereby reducing the time consumed by cleaning the media item and improving the efficiency of cleaning the media item.
