Embodiment 1

1 is a schematic flow chart of a method for displaying a picture according to Embodiment 1. The method of this embodiment can be performed by a picture display device such as a smart TV. As described in FIG. 1, the method may include the following steps:

Step 110: Acquire original picture data after decoding of the currently selected display picture.

Exemplarily, the source of the currently selected display picture may be a local picture stored in a picture display device such as a smart TV, or may be a picture stored in a peripheral such as a U disk or a hard disk connected to a picture display device such as a smart TV. It can also be a picture stored in the cloud obtained by a picture display device such as a smart TV via the Internet.

Exemplarily, the decoded original image data is original image data obtained by decoding the currently selected display image data of the unique format according to the decoding manner of the storage format of the corresponding image.

Before obtaining the original image data after decoding the currently selected display image, if it is determined that the decoded data of the original picture (abbreviated as the original picture) of the currently selected display picture of the user has been stored in the memory, hard disk or disk of the smart TV, this When it is determined that the currently selected display picture is decoded, if the original picture data of the original picture of the currently selected display picture is not stored in the memory, the hard disk or the disk of the smart TV, the current user needs to obtain the current picture. The original picture of the displayed picture is selected for decoding, and the decoded original picture data is obtained.

Optionally, before acquiring the original image data after decoding the currently selected display image, the method may further include:

Decoding the currently selected picture to obtain the decoded original picture data of the currently selected picture; storing the currently selected display in at least one of the memory cache and the disk cache according to a preset picture data cache rule The original image data after the image is decoded.

Optionally, the decoded original image data is stored in a cache. Among them, the cache can include a memory cache and a disk cache. By storing the decoded original image data in the cache, it can be ensured that the user selects the display to be selected in the process of quickly browsing the massive image from left to right in the case that at least one cache space in the memory cache and the disk cache is fixed. The high-speed loading and display of the image reduces the occurrence of abnormalities such as "black screen" or "calorie" or the like, as compared with the technical solution that does not use the cache.

Step 120: According to the currently selected display picture, at least one picture to be selected is obtained according to a preset picture determination rule, and thumbnail data of the picture to be selected is obtained.

The preset picture determination rule may be: performing pre-judgment according to a preset picture priority level according to a preset screening algorithm, and obtaining at least one to-be-selected display picture according to the pre-judgment result.

Optionally, the preset picture priority may be: the currently selected display picture has the highest priority; the closer the picture is to the storage location of the currently selected display picture, the higher the priority, the distance from the currently selected display picture storage. The lower the position, the lower the priority of the picture. For example, the priority of the image may be determined according to the priority identifier carried in the original image data. Therefore, the preset screening algorithm may be: when the image is stored in the cache, the image may be identified according to the priority. After sorting, the storage is performed. Therefore, after the currently selected display image is determined, at least one next selected display image can be determined according to the currently selected display image and image sorting.

The priority identifier of the image (such as time-based or location-based) can be set before the smart device leaves the factory. When the user stores the image, the user-stored images can be classified according to the user's needs (for example, according to the image) The storage time or shooting time or shooting location is classified, and the corresponding priority identifier is added to different images. For example, the preset filtering algorithm may be: in the current time period, the corresponding priority identifier may be added to the image stored by the user according to the order of the storage time. When the user browses the image, the smart device may prioritize according to the image. The level identifier and the currently displayed display picture are determined according to the storage time order, and at least one of the next to be selected display pictures is pushed to the user.

Optionally, the priority identifier of the image may be added by the user, that is, when the user stores the image, the priority identifier corresponding to the stored image may be added according to actual needs. For example, an identifier 1 is added for the picture A, and an identifier 2 is added for the picture B, wherein the priority of the identifier 1 is higher than the priority of the identifier 2. The preset filtering algorithm may also be: the pictures stored by the user may be sorted according to the actual needs of the user, and when the user browses the picture, at least one next to be selected display picture may be determined according to the above sorting. According to the actual needs of users, the default order of the pictures obtained by sorting can meet the needs of users.

Exemplarily, the priority of the picture can also be dynamically changed according to the user's operation. In the implementation process, the user's picture browsing operation behavior can be counted by means of machine learning, so that the degree of fit and tacit agreement between the picture judgment rule executed by the program in the smart device and the historical picture browsing operation of the user is higher, and thus effective According to the currently selected display picture, according to the preset picture judgment rule, the efficiency of the user to select the display picture next is determined. For example, when a user browses a picture in a picture library, the smart device can obtain the browsing time of the user for the picture, and determine the priority of the picture by counting the length of each picture browsing time. If the user searches for the longest browsing time of the picture A within one week, the priority of the picture A can be set to the first level, and the picture A is cached in the position of the first picture in the picture library. In this way, the first picture currently displayed in the process of browsing the massive picture library is the picture A, thereby saving the time for searching for the picture A and improving the user experience.

For example, the preset screening algorithm may also be: in a one-week time period, the system statistics of the smart device find that after the user browses the picture A, the user spends the most time browsing the picture B, that is, the picture B and Picture A is the most relevant, so it can be inferred that after the user has finished browsing picture A, it is possible to browse picture B. In this way, the picture B has the highest priority with respect to the picture A, and the picture B is the picture to be selected for the picture A. Based on the statistics like this, according to the currently selected display picture, according to the preset picture determination rule, at least one next to be selected display picture that the user may wish to browse after browsing the currently selected display picture is obtained.

Optionally, after determining the currently selected display image and the at least one to-be-selected display image, the currently selected display image and the thumbnail data corresponding to the at least one to-be-selected display image may also be determined at the same time. The storage manner of at least one to-be-selected display picture and its corresponding thumbnail data may be selected to be stored using a cache.

Step 130: Load data of the interface to be displayed, and divide the interface to be displayed into a current display interface and at least one hidden invisible interface according to the currently selected display image and the to-be-selected display image.

The current display interface is configured to display an original image of the currently selected displayed image and at least one thumbnail of the to-be-selected display image, and the hidden invisible interface has a preset corresponding to the to-be-selected display image. relationship.

The interface to be displayed is a carrier that currently selects a display image and a display image to be selected. The current display interface is an interface that the user can see, usually the interface where the user is browsing. This interface can show the user the original image of the currently selected display image and the thumbnail of the next selected display image. Correspondingly, the hidden invisible interface is in the invisible area of the user, and is usually a picture display interface that has been browsed by the user or the next picture display interface to be browsed. Since the display images to be selected have been sorted according to the priority, there is a preset correspondence between the hidden invisible interface and the display image to be selected. Optionally, the preset correspondence may be determined according to a priority of the to-be-selected display picture.

After the interface to be displayed is loaded, at least one picture can be displayed on the current display interface. For example, the current display interface may be used to display the original image of the currently selected display picture and the corresponding thumbnail image, wherein the thumbnail image may be displayed floating above, below, above or below the original image according to the preset path, and may be according to a predetermined track. The thumbnail is swiped. Exemplarily, the thumbnail corresponding to the selected display image can also be displayed in the current display interface. For example, in a case that the user does not affect the currently selected display picture, the thumbnails corresponding to the four to-be-selected display pictures may be presented in the four corner positions of the current display interface, or the thumbnails corresponding to the two selected display pictures may be placed. On the left side of the original picture of the currently selected display picture, the other two thumbnails are placed on the right side of the original picture of the currently selected display picture. Exemplarily, the interface to be displayed may be adaptively scaled according to the size of the smart device display screen and the content of the picture to be displayed to enhance the sensory experience of the user.

Optionally, in the process of dividing the interface to be displayed, the current display interface and the hidden invisible interface are not fixed, and the current display interface and the hidden invisible interface may be converted according to a user-initiated browsing switching instruction. For example, in the process of browsing a picture in a left or right direction, the current display interface and the hidden invisible interface will also be in a dynamic conversion process.

Exemplarily, it is assumed that the interface to be displayed is divided into a current display interface and two hidden invisible interfaces distributed on the left and right sides thereof, and the hidden invisible interface on the left side corresponds to the left side of the currently selected display image on the current display interface. Thumbnail, the hidden invisible interface on the right side corresponds to the thumbnail on the right side of the currently selected display image on the current display interface.

When the user selects the thumbnail on the right side of the currently selected display image on the current display interface, that is, the user selects to start browsing the to-be-selected display image corresponding to the thumbnail on the right side of the currently selected display image, the dynamic change process of the display interface is : The hidden invisible interface on the right side of the current display interface becomes the new current display interface; the original current display interface becomes the new current display interface (that is, the hidden invisible interface on the right side of the original current display interface) is hidden on the left side. Visible interface; the hidden invisible interface on the left side of the current display interface becomes the hidden invisible interface on the right side of the new current display interface (ie, the hidden invisible interface on the right side of the original current display interface).

When the user selects the thumbnail on the left side of the currently selected display image on the current display interface, that is, the user selects to start browsing the to-be-selected display image corresponding to the thumbnail on the left side of the currently selected display image, the dynamic change process of the interface is: The hidden invisible interface on the left side of the current display interface becomes the new current display interface; the original current display interface becomes the new current display interface (ie, the hidden invisible interface on the left side of the original current display interface) is hidden from the right side. Interface; the hidden invisible interface on the right side of the current display interface becomes the hidden invisible interface on the left side of the new current display interface (ie, the hidden invisible interface on the left side of the original current display interface).

This ensures that the user can directly call in the memory, memory buffer or disk cache area when the user selects the thumbnail on the right or left side of the currently selected display image displayed on the current display interface for the next picture browsing. The newly created corresponding invisible interface data is not newly created, and the original image corresponding to the thumbnail is obtained from the memory, the memory buffer area or the disk buffer area according to the correspondence between the hidden invisible interface and the thumbnail displayed on the current display interface. The data is used to improve the stability of the loading of the display interface of the next picture and the corresponding original image data and the efficiency of the display interface reuse.

At the same time, since the picture in the current display interface has been updated to the picture corresponding to the left or right thumbnail of the currently selected display picture, the system such as the smart device can determine the rule according to the preset picture according to the updated picture. Get the new two to-be-selected display images, and get the original image and thumbnail data of the two selected display images, then store the data in the memory or disk cache, and place the thumbnails in the new currently selected display. Both sides of the picture are for the user to choose to continue browsing, and the smart device system can perform the above steps cyclically according to the user's operation.

Before the step of loading the data of the interface to be displayed, the method may further include: creating an interface to be displayed, obtaining data of the interface to be displayed, and storing data of the interface to be displayed in a cache. And disk caching. The setting is such that the data of the interface to be displayed can be directly obtained when the interface is displayed next time, without additional resources and time to newly create the interface to be displayed and generate data of the display interface to be created, which can be smoothly loaded at a high speed. UI. Exemplarily, creating a current display interface and at least one hidden invisible interface may include: determining a number of hidden invisible interfaces according to a memory device size, a model, and the like, and determining a number of hidden invisible interfaces; Set interface storage rules to store the current display interface and hide the data of the invisible interface in the cache.

For example, for a smart device with a memory size of 2G or less (for example, a smart TV), three interfaces (such as interface A, interface B, and interface C) can be selected to satisfy the user's need for high-speed switching browsing. The interface A is the current display interface, the interfaces B and C are 2 hidden invisible interfaces, and the invisible interfaces B and C are hidden for memory pre-buffering (the hidden invisible interfaces B and C and the to-be-selected display image are hidden at this time) There is a corresponding relationship), and the current display interface A presents the currently selected display picture to the user. When the user is browsing the current display interface A, the left side of the current display interface A is the hidden invisible interface B stored in the memory cache, and the right side is the hidden invisible interface C stored in the memory cache. Illustratively, for devices with a memory size of 2G or more (such as 4G or 8G) (such as smart TV), 5 interfaces can be cached. 2 is a schematic diagram of interface conversion provided in Embodiment 1. As shown in FIG. 2, four interfaces (numbers: 1, -1, 2, and -2) are used as hidden invisible interfaces, and one interface (number: 0) Display the currently selected display picture to the user as the current display interface. After obtaining the picture browsing switching instruction of the user, the above five interfaces may display the target picture that the user intends to switch the browsing according to the switching instruction.

By determining the number of hidden invisible interfaces based on the memory attributes of the smart device, the utilization of memory resources can be improved. The data of the hidden invisible interface is stored in the cache, which can effectively manage the display interface of the smart device, and the utilization of the display interface can also be improved, and the memory usage of the invalid display interface is also avoided. When the user quickly browses the picture, the display interface is displayed to the user without interruption, thereby improving the user experience.

The storage processing of the data of the interface to be displayed in the cache and the storage processing of the original image data after decoding in the cache may be performed synchronously, but may be performed separately, and the execution order is not limited.

Step 140: Load the original image data and the thumbnail data on the current display interface to display the original image and the thumbnail image.

Optionally, in order to bring a good sensory experience to the user, the data of the current display interface and the data of the currently selected display image are synchronously loaded. In the process of loading the decoded original image data of the original picture of the currently selected display picture, the data may be sequentially loaded according to the priority of the original picture. In the process of the user quickly browsing the picture, the loading speed of the picture data is adapted to the speed at which the user switches the display interface, so that the setting is for the user to quickly browse the massive pictures without "black screen" or "calorie". phenomenon.

After the data of the current display interface and the decoded original image data of the original picture of the currently selected display picture are loaded, the currently selected display picture can be displayed on the current display interface. Exemplarily, the thumbnail corresponding to the selected display image may also be displayed on the left side, the right side, the upper side or the lower side of the currently selected display picture in the current display interface, so as to facilitate the user to Quickly and easily select the next target image to be viewed.

Optionally, after the displaying the original image and the thumbnail, if the user's browsing switching instruction is obtained, the current display interface and the currently selected display image are also updated, and step 110- The method provided by 140 displays the picture. Illustratively, when the thumbnail is selected as the currently selected display image, the hidden invisible interface corresponding to the thumbnail is updated to the new current display interface, and the original current display interface is updated to the new hidden invisible interface. Illustratively, three display interfaces A, B, and C are stored in the cache in the smart TV. When the user is browsing the current display interface A, the left side of the current interface A is the hidden invisible interface B stored in the memory cache, and the right side is the hidden invisible interface C stored in the memory cache. When the instruction to browse to the right is obtained, the hidden invisible interface C stored on the right side replaces the currently visible interface A. At this time, the invisible interface C is hidden as a new currently visible interface, and the original current display interface A is used as a new one. The hidden invisible interface C. At the same time, the picture in the new current display interface is also replaced with the original hidden image in the invisible interface C. When the instruction to browse to the left is obtained, the hidden invisible interface B of the left cache will be switched to the new current display interface, and the image in the new current display interface will also be hidden from the original invisible interface B. replace.

This embodiment provides a method for displaying a picture, which can be applied to a smart device. In the process of quickly browsing a large number of pictures by a smart device such as a smart TV, since the data of the current interface to be displayed and the original picture data of the currently selected display picture are already acquired in the memory of the smart TV, On the display interface, the currently selected displayed image can be loaded and displayed quickly and clearly. At the same time, according to the currently selected display picture, according to the preset picture judgment rule, at least one picture to be selected different from the currently selected display picture is selected from the massive pictures stored in the smart TV, and obtained The thumbnail data of the to-be-displayed picture is displayed, and the thumbnail is displayed on the current display interface. After the user browses the original picture of the currently selected display picture, the thumbnail can be selected more directly and conveniently, so that the user can quickly browse the next picture. And by dividing the interface to be displayed into a current display interface and at least one hidden invisible interface, and the technical means of the preset correspondence relationship between the hidden invisible interface and the to-be-selected display image, thereby smoothly ensuring that the user can On the original hidden invisible interface (currently the current display interface), the thumbnail or original image of the next selected display image is browsed at high speed and clearly. By adopting the above technical solution, the display interface of the smart device can display a large number of pictures quickly and clearly, and the abnormality or non-smoothness such as “black screen” or “katon” does not appear, which enhances the sensory experience of the user.

Embodiment 2

FIG. 3 is a schematic flow chart of a method for displaying a picture according to Embodiment 2. The second embodiment is optimized on the basis of the first embodiment. Referring to FIG. 3, the second embodiment includes the following steps:

Step 210: Decode the currently selected picture to obtain the original picture data after the currently selected display picture is decoded.

Step 220: Store, according to a preset picture data caching rule, the original picture data after decoding of the currently selected display picture in at least one of the memory cache and the disk cache.

Optionally, the thumbnail data corresponding to the currently selected display image may also be obtained and stored.

Step 230: According to a preset picture determination rule, obtain a to-be-selected display picture, and decode the to-be-selected display picture based on at least one of a preset abbreviated ratio and a preset memory multiplexing rule to obtain the The thumbnail data after the picture is decoded is selected.

Illustratively, for each picture, it needs to be decoded before it is displayed for the first time. For the already decoded picture data that has been stored in the memory cache or the disk cache, when the picture data is loaded, there is no need to decode, and the picture data can be directly obtained and displayed. Therefore, according to the preset picture determination rule, after determining the to-be-selected display picture, it can be determined whether there is corresponding decoded thumbnail data in the memory cache or the disk cache, and there is corresponding decoded thumbnail data. When it is, it means that the to-be-selected display picture does not need to be decoded, and can be directly loaded. If there is no corresponding decoded thumbnail data, the selected display picture is decoded to obtain decoded thumbnail data. The preset memory reuse rule can time-multiplex the memory through memory sharing or memory swapping in a certain memory.

Illustratively, based on a preset thumbnail ratio (such as 1:8) and/or a preset memory multiplexing rule of the thumbnail relative to the original image of the to-be-selected display image, the corresponding image data of the display image to be selected may be determined. Thumbnail data. The preset thumbnail ratio is a thumbnail displayed on the screen, and does not affect the effect that the user can determine the currently to-be-selected display image according to the thumbnail.

Step 240: Store thumbnail image data after the selected display picture is decoded in at least one of the memory cache and the disk cache according to a preset picture data cache rule.

By storing the image data in the cache, the efficiency of decoding, loading, and displaying of a large number of images during dynamic browsing can be improved, and memory resources can also be saved.

Exemplarily, the preset picture data caching rule may include: buffering the picture data according to a preset page replacement algorithm. The preset page replacement algorithm may be selected as a Least Recently Used (LRU) algorithm. In the implementation process, the size of at least one of the decoded original image data and the thumbnail data stored in the memory cache and/or the disk cache may be determined according to the software and hardware configuration attributes of the smart device, such as a smart TV. . For example, if the size of the cache of the original image data and/or the thumbnail data that needs to be stored currently exceeds the preset memory cache and/or the remaining storage space of the disk cache (for example, 100 M), the preset time is counted ( For example, the number of times the original image data and/or the thumbnail data that have been stored in the 15 days are viewed by the user. If the counted number of times of browsing is lower than a preset threshold (for example, 3 times), the number of times of browsing is based on the LRU algorithm. The original image data and/or thumbnail data below the preset threshold are deleted from the cache, providing a buffer space for the determined number of original image data and/or thumbnails to be browsed. The advantage of this setting is that the size of the cache can be dynamically and effectively controlled, so that the cache space of the smart TV can be in a reasonable range, and the work efficiency of decoding, loading and displaying the picture when the user browses a large number of pictures is improved, and the user experience is improved.

When the original image data is stored in the memory buffer, in the case of ensuring that the original image data is optimally displayed, it is generally set to store 2 to 3 original decoded data, and the size is about 2 megabytes (M). When storing thumbnail data in the memory buffer, when it is ensured that the picture data can be switched at a relatively fast speed, it is generally set to store 8 to 10 pieces of thumbnail data, and the size is about 6 megabytes (M). For some high-profile smart TVs, the size of the stored thumbnail data can be increased to 12 megabytes (M) due to its large memory space, which improves the generation, display and loading speed of thumbnails.

Exemplarily, the manner of storing by using the disk cache may include the following two situations:

1. The sub-thread preloads the thumbnail data with high priority to ensure that the original image data can be directly converted into thumbnails and stored in the disk cache when the original image data has no thumbnails, thereby increasing the loading speed of the thumbnails. The size of the stored thumbnail data can be adjusted according to the space of the disk, and generally 80 megabytes (M) of thumbnail data can be cached.

2. The sub-thread is used to store the original image data after the currently selected display image is decoded, and the original image data can be directly displayed during the second loading. In this case, since the decoded original image data still occupies a large space, for the decoded original image data, generally 100 megabytes (M) of data can be stored.

In step 220, the currently selected display picture data and the corresponding thumbnail data are stored in the cache, and the corresponding thumbnail data decoded in the step 240 to be decoded in the cache may be stored in the cache, or may be performed asynchronously.

Step 250: Acquire original picture data and thumbnail data after decoding of the currently selected display picture, and thumbnail data after decoding of the selected display picture.

For example, the thumbnail of the display image to be selected is generally selected to be displayed during the high-speed browsing of the image by the user, that is, as the display interface is continuously switched, the currently selected displayed image on the current display interface is also Keep switching. According to the preset picture pre-judging rules, the thumbnails displayed on the current display interface are also dynamically updated. When the user stops browsing at a high speed, the original image data after the selected display image is decoded is obtained. At this time, the thumbnail data is replaced by the corresponding original image data, that is, the current display interface presents the original image data. Through the above dynamic management of the picture, the loading and display speed of the picture can be improved.

Step 260: Load data of the interface to be displayed, and divide the interface to be displayed into a current display interface and at least one hidden invisible interface.

Step 270: Load the original image data decoded by the currently selected display image and the thumbnail data to be selected and displayed in the current display interface and display.

Exemplarily, if the user wants to view the picture at a high speed in the right direction, the user can always send the right picture browsing switching instruction through the remote control or the touch screen (for example, long press the right button of the remote control or continuously click the screen). "Right" indicator button, etc.).
