The following describes in detail the implementation of the embodiments of the present invention with reference to examples.
Example 1
This example describes a detailed processing flow of the above-mentioned picture adaptation method, and fig. 3 is a detailed flow chart of the picture adaptation method according to example 1 of the present invention, as shown in fig. 3, the method mainly includes the following steps:
in step 301, the server stores terminal model information and/or screen size information of the mobile terminal (the screen size of the terminal can be identified by screen resolution). The larger the amount of information in the database, the better, at least all mainstream products of mainstream mobile terminal manufacturers should be covered, and the screen size is the information of major concern, but if possible, the market share can also be used as an important data in the analysis. The complete terminal information data can reach 2 ten thousand terminal data, and a general field database can have about 3000 data.
The server analyzes the terminal data to obtain the most common N resolutions as an analysis result, where the N value may be configured according to actual conditions, and a simple analysis process is to count only the percentage of each screen resolution among all screen resolution data, and take the N resolution with the highest percentage as an analysis result.
In the server, a function may also be provided to manually add data to the analysis results, some special resolution data may be added, e.g. 200 x 800. However, in general, no special resolution needs to be added manually, since the analysis result covers more than 90% of the terminals, most users can be satisfied, and for the screen size of the terminal with a special size, even if the screen size is not exactly the same as the screen size, the selected picture is not larger than the screen size, and the display effect is not too poor. Such as: for a mobile terminal with a screen size (width x height) of 128 x 320 for which a picture copy of the 128 x 160 specification is selected, the picture does not exceed the screen size.
In step 303, the server converts the original picture on the mobile portal into an ith picture copy suitable for the ith resolution according to the ith resolution in the analysis result, and stores the ith picture copy on the server, wherein i is a positive integer and i < ═ N.
Specifically, the server converts the original picture on the mobile portal into the ith copy (height H, width W) according to the height (H1) and width (W1) of the ith resolution in the analysis result, and the size of the copy conforms to H ≦ H1 and W ≦ W1. Preferably, the aspect ratio of the copy may be consistent with the original image to ensure that the picture viewed by the user is not distorted. Considering that a User Agent (User Agent) border of the mobile terminal may occupy a certain screen edge, H may be slightly smaller than H. Preferably, in the case that the original picture is smaller than or equal to the screen sizes of all terminals, the size conversion of the picture may not be performed, and at this time, the picture copy is the original picture itself.
The generated picture copies can be organized according to a certain directory (for example, the ith resolution is put in the same directory), and are uniformly stored on the server, if a cluster is used, a special picture server can be used, a static page server technology is used, and the performance is greatly improved. For the requirement of storage space, the common terminal sizes are: 128 x 128, 128 x 160, 176 x 220, 240 x 320, with an original image (602 x 1010) with a size of 55.9K, four picture copies with a resolution of 286 x 480, 190 x 320, 131 x 220, 95 x 160 are generated, the size is 16.3K, 8.9K, 5.35K, 3.4K, the occupied storage space is about 34K, and is not more than one time of the original image.
For a picture, only a plurality of copies with different sizes need to be generated in advance during uploading, and the picture copies can be reused. If ten thousand users access the picture, ten thousand times need to be generated in real time by using the real-time generation method, and only a plurality of times (4 times in the example) need to be generated in advance by using the method provided by the embodiment of the invention.
In step 304, the mobile terminal sends a picture request message and information of the mobile terminal to a server (e.g., a mobile portal), wherein the picture request message specifies a target picture, and the information of the mobile terminal specifies the mobile terminal used by a user, and the information of the mobile terminal may include at least one of the following: the model of the mobile terminal, and the screen size of the mobile terminal.
In step 305, after receiving the picture request message of the mobile terminal and the information of the mobile terminal (or the information of the mobile terminal may also be included in the picture request message), the server (e.g., the mobile portal) selects the jth copy with the optimal target picture according to the information of the mobile terminal and returns the jth copy to the mobile portal. Specifically, the above process may include the following processes of step 1 to step 3:
step 1, under the condition that the information of the mobile terminal comprises the model of the mobile terminal, the server searches the screen size (which can be represented by resolution) of the terminal from the information of all the mobile terminals stored in the server according to the model of the mobile terminal (or the model of the mobile terminal in the picture request message); in the case where the information of the mobile terminal includes the screen size of the mobile terminal or both the model and the screen size of the mobile terminal, the server may directly obtain the screen size (which may be expressed in terms of resolution) of the mobile terminal.
And 2, the server calculates the optimal picture resolution of the mobile terminal (namely, selects a picture copy corresponding to the mobile terminal) as the jth resolution in the analysis result according to the resolution of the mobile terminal, wherein the picture copy of the jth resolution is a picture to be fed back to the mobile terminal, and establishes the optimal adaptation relationship (namely, the corresponding relationship) between the terminal model and the jth resolution. Preferably, in the case that the screen size of the mobile terminal is larger than that of the original picture, the best picture resolution of the mobile terminal is the resolution of the original picture.
As a specific example, in step 2, the optimal picture resolution satisfies: the height of the picture copy is less than or equal to the height of a screen of the mobile terminal, the width of the picture copy is less than or equal to the width of the screen of the mobile terminal, and the predetermined difference value is less than or equal to the predetermined difference value of other picture copies in the plurality of picture copies, wherein the predetermined difference value is a | H-H | + b | W-W |, H is the height of the picture copy, H is the height of the screen, W is the width of the picture copy, W is the width of the screen, a and b are preset weights, and the values of a and b can be preset according to actual conditions.
For example, a picture copy satisfying that the height of the picture copy is equal to or less than the height of the screen of the mobile terminal and the width of the picture copy is equal to or less than the width of the screen of the mobile terminal is selected, then the difference between the height (or width) of the screen and the height (or width) of the picture copy is calculated, and the resolution of the picture copy with the smallest difference is selected as the best picture resolution.
And 3, the server puts the adaptive relation into a cache block, and directly reads the adaptive relation from the cache without repeatedly calculating and selecting the adaptive relation when reading the adaptive relation of the same terminal model or the same terminal screen size next time. The process may include: after receiving the picture request message and the information of the mobile terminal (or the information of the mobile terminal is carried in the picture request message), the server first performs matching in a cached adaptation relationship, determines whether a resolution of a picture copy corresponding to the information of the mobile terminal exists, if so, the resolution found in the adaptation relationship is the best picture resolution of the mobile terminal, otherwise, the best picture resolution of the mobile terminal is determined through the steps 1 and 2, and preferably, the step 3 is executed after the best picture resolution is determined. The LRU algorithm may be used for caching, that is, data that is used least recently is flushed out of the cache, so as to avoid occupying too much memory of the system, and other algorithms may also be used.
And step 306, the server reads the corresponding picture copy according to the adaptation result and returns the picture copy to the mobile terminal.
In the above processing flow, step 302 is an optional step, and in the case that step 302 is not included, step 303 may reduce the original picture by different multiples to obtain multiple picture copies, or perform conversion according to a preset size, or the like.
It should be noted that the size is expressed by resolution in the above example, and in practical applications, the size may also be expressed by other parameters (for example, the height and width value cm). Moreover, in the above example, the correspondence between the information of the mobile terminal cached by the server and the picture copy corresponding to the mobile terminal is represented by the adaptation between the information of the mobile terminal and the optimal picture resolution, and preferably, the number or index of the picture copy may also be applied instead of the optimal picture resolution, which may further save the cache space.
