Fig. 1 is a flowchart of a method for preloading pictures provided by an embodiment of the present disclosure, where the present embodiment is applicable to a situation where page content on an electronic device is loaded and displayed, and the method may be executed by an apparatus for preloading pictures provided by an embodiment of the present disclosure, where the apparatus may be implemented by software and/or hardware, and may be integrated in an electronic device such as an intelligent terminal.
As shown in fig. 1, the method for preloading pictures includes:
s110, responding to a target picture viewing event, and preloading a reduced picture of the target picture from a storage terminal of the target picture; and the reduced picture of the target picture is obtained by reducing the resolution of the target picture.
When a user opens a page through the intelligent terminal, if the page contains a picture, the user can determine that the user needs to view the picture in the page, and then the user can determine that the user needs to view the picture as a target picture viewing event. Since the page is opened based on the network support, the target picture is loaded through the network, in this case, if the user opens the page, the text content is displayed completely, and the picture cannot be loaded completely in time, the page picture loading is blocked. For example, only a small area on the top of a picture is displayed, and a small area can be loaded again after a long time, which is very bad for the user's page browsing experience, and if picture information is important, the user can only wait for the picture loading to complete to browse the picture information, which affects the user's page browsing time.
In order to solve the problem, the method and the device adopt the mode that when a target picture viewing event is responded, the reduced picture of the target picture is preloaded from the storage end of the target picture. The storage end of the target picture may be a server, or may be a picture storage location of other local devices. After a user opens a certain page, if a picture exists in the page, the server often returns a picture link through a network, and the picture link can point to a storage position of the picture and can be used for the terminal to load the picture. In the technical scheme, whether a reduced picture exists in the storage position of the target picture can be determined in the process of loading the target picture or loading the target picture, and if yes, the reduced picture can be preloaded. And the reduced picture of the target picture is obtained by reducing the resolution of the target picture. For example, the resolution of the original picture is 1080P, and the resolution of the downscaled picture may be 270P. The advantage of this arrangement is that the effect of quickly displaying the picture content in the page can be achieved by preloading the reduced pictures.
S120, loading the target picture; and carrying out fuzzy processing on the reduced picture according to the loading progress of the target picture and displaying the reduced picture.
Since the resolution of the reduced picture is reduced, the picture content therein is blurred or the picture information is lost, and if the user needs a relatively clear picture content, preloading the reduced picture cannot meet the user's needs. Therefore, the target picture can be loaded in the preloading process or after the preloading is finished. In the technical solution, the blur processing may be performed on the reduced picture according to the loading progress of the target picture, for example, as the loading progress of the target picture changes, the sharpness of the blur processing of the reduced picture also changes, for example, from very blurred to gradual sharp, or from a larger blur radius to a smaller blur radius. The algorithm for blurring the reduced picture may be gaussian blur, mean blur, median blur, and the like. Therefore, in the loading process of the target picture, the dynamic fuzzy effect of the reduced picture can be displayed for the user, the display of the picture information is accelerated on the premise that the user browses the whole content of the page, and the target picture is loaded so as to meet the requirement of the user on detailed browsing of the picture information.
In the technical scheme, in the process of loading the target picture, the reduced picture can be subjected to fuzzy processing and displayed according to the loading progress of the target picture. The fuzzy processing has the advantages that the fuzzy processing parameters can be controlled, the reduced picture is displayed to the user from fuzzy to clear, the user can perceive the content of the current picture or the loaded picture, and the effect of dynamic display of the picture is achieved.
And S130, if the target picture is loaded, replacing the blurred reduced picture with the target picture for displaying.
And when the target picture is detected to be loaded completely, replacing the blurred reduced picture with the target picture for displaying. Through the replacement operation, the originally fuzzy picture can be replaced by a clear picture for the user to view.
In this embodiment, optionally, before preloading a reduced picture of a target picture from a storage end of the target picture, the method further includes: and sending a reduced picture acquisition request of the target picture to a storage terminal of the target picture so as to receive data of the reduced picture. The reduced picture can be loaded from the storage end of the target picture in a form of sending a reduced picture acquisition request of the target picture to the storage end of the target picture. The target picture storage end simultaneously has the target picture and the reduced picture of the target picture. If the target picture is directly recorded, the problem that the user is delayed in viewing the picture in the page can be caused, so that the request for obtaining the reduced picture can be preferentially sent before the target picture is loaded, the reduced picture is provided by the storage terminal for the terminal equipment to pre-load and display, and the purpose that the rough content of the picture in the page can be quickly provided for the user is achieved.
According to the technical scheme provided by the embodiment of the disclosure, in response to a target picture viewing event, a reduced picture of a target picture is preloaded from a storage terminal of the target picture; the reduced picture of the target picture is obtained by reducing the resolution of the target picture; loading the target picture; carrying out fuzzy processing on the reduced picture according to the loading progress of the target picture and displaying the reduced picture; and if the target picture is loaded, replacing the blurred reduced picture with the target picture for displaying. By adopting the technical scheme provided by the disclosure, the aim of displaying the dynamic fuzzy effect of the reduced picture for the user in the loading process of the target picture can be fulfilled.
On the basis of the above technical solution, optionally, the blurring processing and displaying the reduced picture according to the loading progress of the target picture includes: acquiring the loading progress of the target picture; and determining a Gaussian blur degree parameter according to the loading progress, and performing Gaussian blur processing on the reduced picture according to the determined Gaussian blur degree parameter and displaying the reduced picture. Wherein the loading progress of the target picture can be represented by a percentage of loading, for example, 10%, 20%, and so on. In the scheme, the fuzzy degree parameter can be set to include 3-10 levels, and the fuzzy degree parameter is correspondingly reduced when the loading progress of the target picture is increased. Therefore, the process that the picture is blurred to be clear can be reduced along with the loading of the target picture, and the use experience of a user in the process of browsing the page can be improved.
On the basis of the above technical solutions, optionally, the obtaining of the loading progress of the target picture includes: and determining the loading progress of the target picture by calling the data loading quantity of the target picture assembly and the total data quantity of the target picture. The target picture component can be a component used for loading the target picture and displaying the target picture on a page. The text and pictures in the page may be loaded and displayed by different components. In this embodiment, the component describing the reduced picture may be a target picture component, or a reduced picture component having the same display position and range in the page as the target picture component may be separately constructed. Wherein the reduced picture assembly acts as a subcomponent of the target picture assembly such that the display of the reduced picture assembly content can be canceled after the target picture assembly loading is complete. Additionally, the target picture element can also be a subcomponent of the reduced picture element, such that the display of the reduced picture element content can be overlaid after the target picture element has been loaded. The technical scheme has the advantage that the effect of monitoring the loading progress of the target picture component can be achieved.
On the basis of the foregoing technical solutions, optionally, determining a gaussian blur degree parameter according to the loading progress, and performing gaussian blur processing on the reduced picture according to the determined gaussian blur degree parameter and displaying the reduced picture, including: determining that the fuzzy radius is gradually reduced according to the gradual increase of the loading progress, so that the result of the fuzzy processing on the reduced picture is from fuzzy to clear and is displayed; or determining that the blurring degree is gradually reduced according to the gradual increase of the loading progress, so that the blurring processing result of the reduced picture is from blurring to being clear and is displayed. For the control of the fuzzy degree, the fuzzy radius can be controlled to be gradually reduced to enable the display of the reduced picture to be gradually clear. The blur level parameter may also be controlled to determine. For example, through gaussian blur, the magnitude of each weight in the convolution matrix can be determined to determine the degree parameter of gaussian blur. According to the technical scheme, the dynamic display process from blurring to clearness can be carried out on the reduced picture in the target picture loading process through the arrangement, the phenomenon of pause can not occur, and the browsing experience of a user on the page is improved.
Fig. 2 is a flowchart of a method for preloading pictures according to an embodiment of the present disclosure. On the basis of the scheme, the scheme is specifically optimized as follows: after sending the reduced picture acquisition request of the target picture to the storage terminal of the target picture, the method further comprises: if the information that the reduced picture does not exist is returned by the storage end of the received target picture, sending a reduced picture generation request of the target picture to the storage end of the target picture, so that the storage end of the target picture performs resolution reduction processing on the target picture based on the generation request, and returning the data of the obtained reduced picture.
As shown in fig. 2, the method for preloading pictures includes:
s210, responding to a target picture viewing event, and sending a reduced picture acquisition request of the target picture to a storage terminal of the target picture; and performs S220 or S230.
After detecting the target picture viewing event, the intelligent terminal can send a reduced picture acquisition request of the target picture to the storage terminal of the target picture, and further determine which specific flow in the following branches goes to according to data returned by the storage terminal.
S220, if the information that the reduced picture does not exist is returned by the storage end of the target picture, sending a reduced picture generation request of the target picture to the storage end of the target picture, so that the storage end of the target picture performs resolution reduction processing on the target picture based on the generation request, and returning the data of the obtained reduced picture.
If the information of the reduced picture does not exist in the received data display storage end, a reduced picture generation request of the target picture can be further sent to the storage end of the target picture, so that the storage end of the target picture performs resolution reduction processing on the target picture based on the generation request, and returns the obtained data of the reduced picture. The technical scheme is suitable for the condition that only the target picture exists in the storage terminal, and under the condition, the reduced picture can be generated and preloaded when the target picture is accessed for the first time. And reserving the reduced picture at a storage end for preloading use of the intelligent terminal in the subsequent target picture browsing process.
And S230, if the data of the reduced picture is received, loading the obtained reduced picture.
