Description

Picture loading method and device and electronic equipment

Technical Field

The present invention relates to the field of image processing technologies, and in particular, to an image loading method and apparatus, and an electronic device.

Background

When a user browses a webpage on the internet, the webpage shows some pictures containing specific content to the user. For example, when a shopping webpage loads a commodity picture, the shopping webpage downloads a thumbnail of the commodity picture from the network and then displays the thumbnail to the user. When a user clicks the thumbnail, the shopping webpage downloads the picture with the highest resolution corresponding to the thumbnail from the network, then loads the picture to the position corresponding to the shopping webpage, and displays the picture to the user. Through the picture loading mode, the user can see the clearest picture. However, this loading method has two downloading processes, which results in a high user traffic overhead and a long time-consuming picture loading process.

In order to solve the above problems, the mainstream solutions at present are: fresco is taken as a picture loading frame, wherein Fresco is an opening source frame issued by Facebook. The cache in the open source frame is divided into a disk cache and a memory cache, wherein the memory cache is divided into a Bitmap (Bitmap file) cache and a memory cache of an undecoded picture. In order to enable the user to see the clearest picture when clicking on the thumbnail picture. When the picture is loaded in the webpage, the picture is firstly searched in the cache, if the picture cannot be searched, the picture with the highest resolution ratio is downloaded to the cache, and the thumbnail of the picture is displayed to a user. When a user needs to check the picture with the highest resolution, the user clicks the thumbnail of the picture, the browser receives a loading instruction for loading the picture with the highest resolution corresponding to the picture by the user, and the browser reads the picture from the cache and displays the picture with the highest resolution to the user.

However, if the user browses the web page, when the user clicks the thumbnail of the picture on the web page, the browser receives a loading instruction for the user to load the picture with the highest resolution corresponding to the picture, and the browser needs to download the picture with the highest resolution, so that the consumed flow is large.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

In the prior art, the user can see the clearest picture when clicking the thumbnail picture. When the webpage loads the picture to be processed, downloading a picture with the highest resolution of the picture to be processed, and displaying the thumbnail of the picture to be processed to a user. When a user needs to view a picture with the highest resolution of a picture to be processed, the user clicks a thumbnail of the picture to be processed, the electronic device 11 where the browser is located receives a loading instruction of the user to load the picture with the highest resolution corresponding to the picture to be processed, the electronic device 11 where the browser is located downloads the picture with the highest resolution of the picture to be processed from the network server 12, and the picture with the highest resolution of the picture to be processed is displayed to the user. However, if the user browses the web page, when the user clicks the thumbnail of the to-be-processed picture, the browser receives a loading instruction for the user to load the picture with the highest resolution corresponding to the to-be-processed picture, and the browser needs to download the picture with the highest resolution of the to-be-processed picture, so that the consumed flow is large. In order to solve the problem of the prior art, an embodiment of the present invention provides a method, an apparatus, and an electronic device for loading a to-be-processed picture, where fig. 1 is an application scene schematic diagram of an embodiment of the present invention, as shown in fig. 1, when a user clicks a thumbnail, an electronic device 11 where a browser is located downloads a thumbnail a-1 of a to-be-processed picture a from a network server 12, and then determines whether the size of the to-be-processed picture a is larger than the size of the thumbnail a-1, or determines whether the resolution of the to-be-processed picture a is larger than the resolution of the thumbnail a-1, when the size of the to-be-processed picture a is larger than the size of the thumbnail a-1, and/or when the resolution of the to-be-processed picture a is larger than the resolution of the thumbnail a-1, the thumbnail a-1 of the to-be-processed picture a is enhanced by using a picture enhancement algorithm, so as to obtain the to-be-processed picture a, compared with the picture with the highest resolution ratio needing to be downloaded in the prior art, the method has the advantages that the required flow is less, and the flow can be saved for the user.

The embodiment of the invention provides a to-be-processed picture loading method, a to-be-processed picture loading device and electronic equipment, and firstly introduces the to-be-processed picture recording method provided by the embodiment of the invention.

Fig. 2 is a schematic flowchart of a first method for loading a to-be-processed picture according to an embodiment of the present invention, and fig. 3 is a schematic diagram of a principle of the method for loading the to-be-processed picture according to the embodiment of the present invention; as shown in fig. 2 and 3, the method includes:

s201: and downloading the thumbnail of the picture to be processed according to the obtained loading instruction, and obtaining the resolution parameter and the size parameter of the picture to be processed.

Illustratively, when the user browses a web page, for example, when shopping on the web, the electronic device 11, such as a mobile phone, a computer, etc., displays the thumbnail a-1 of the to-be-processed picture a at the position of the to-be-processed picture a. If the user is interested in the content corresponding to the thumbnail A-1 of the picture A to be processed, the user clicks the thumbnail A-1 to observe the details of the thumbnail A-1, the clicking behavior of the user can be used as a loading instruction, and the loading instruction can be a picture loading request. The size of the to-be-processed picture a set by the webpage is inconsistent with the size of the thumbnail a-1, and the resolution of the to-be-processed picture a set by the webpage is inconsistent with the resolution of the thumbnail a-1, so that the resolution parameter and the size parameter of the to-be-processed picture a also need to be acquired.

It can be understood that when the user opens the web page, the web page loads the thumbnail a-1 of the picture a to be processed, but does not load a high-definition picture or a picture with the highest resolution or a picture with the largest size of the picture to be processed.

In practical application, the process of acquiring the loading instruction can be completed by the picture request module; the process of downloading the thumbnail of the picture to be processed can be realized by a network downloading module, and the thumbnail of the picture to be processed can be obtained from a network. The process of fetching a load instruction may be implemented by the following code:

void request(Image Request request)；

the process of downloading the thumbnail of the picture to be processed can be realized by the following codes:

EncodedImage newNetworkFetchProducer(ImageRequest request)。

s202: and judging whether the resolution of the picture to be processed is greater than the resolution of the thumbnail of the picture to be processed and/or whether the size of the picture to be processed is greater than the size of the thumbnail of the picture to be processed, if the resolution of the picture to be processed is greater than the resolution of the thumbnail of the picture to be processed and/or the size of the picture to be processed is greater than the size of the thumbnail of the picture to be processed, executing step 203, if the resolution of the picture to be processed is not greater than the resolution of the thumbnail of the picture to be processed and/or the size of the picture to be processed is not greater than the size of the thumbnail of the picture to be processed, executing step 205, and ending.

Illustratively, according to the resolution parameter and the size parameter of the to-be-processed picture a acquired in step S201, the determination manner in step S202 includes the following three ways:

comparing the resolution of the picture A to be processed with the resolution of the thumbnail A-1, and judging whether the resolution of the picture A to be processed is greater than the resolution of the thumbnail A-1;

comparing the size of the picture A to be processed with the size of the thumbnail A-1, and judging whether the size of the picture A to be processed is larger than the size of the thumbnail A-1;

and thirdly, comparing the resolution of the picture A to be processed with the resolution of the thumbnail A-1, then comparing the size of the picture A to be processed with the size of the thumbnail A-1, and judging whether the size of the picture A to be processed is larger than the size of the thumbnail A-1 or not under the condition that the resolution of the picture A to be processed is larger than the resolution of the thumbnail A-1.

If any of the three determination methods is yes, step S203 is executed, otherwise step S205 is executed.

For example, if the resolution of the to-be-processed picture a obtained in step S201 is 1000 × 1000, the size is 50 × 50 mm. And the resolution of the thumbnail is 300 × 300, and the size is 30 × 30mm, then the resolution of the to-be-processed picture a is greater than that of the thumbnail a-1, and step S203 is executed.

In practical applications, the process of step S202 may be completed by the hard disk cache module.

It can be understood that the judgment of whether the resolution of the picture to be processed is greater than the resolution of the thumbnail of the picture to be processed and/or whether the size of the picture to be processed is greater than the size of the thumbnail of the picture to be processed means that whether enhancement processing needs to be performed on the thumbnail of the picture to be processed.

S203: and carrying out picture enhancement processing on the thumbnail of the picture to be processed by utilizing a preset picture enhancement algorithm.

Illustratively, the thumbnail A-1 is subjected to picture enhancement by using a picture enhancement algorithm so as to enhance the thumbnail to the same size and/or resolution as the picture A to be processed, so as to obtain an enhanced picture A-2 of the thumbnail A-1.

For example, the resolution of thumbnail a-1 may be enhanced to 1000 x 1000; or enhance the size of thumbnail a-1 to 50 x 50 mm; or enhance the size of thumbnail a-1 to 50 x 50mm while enhancing the resolution of thumbnail a-1 to 1000 x 1000.

In practical applications, a picture enhancer may be used to perform picture enhancement processing on the thumbnail of the picture to be processed. In addition, it may be the prior art to enhance the picture by using the picture enhancement algorithm, which is not described herein again, and the picture enhancement algorithm includes, but is not limited to, a logarithmic picture enhancement algorithm and an exponential picture enhancement algorithm.

S204: and taking the thumbnail of the picture to be processed after the picture enhancement processing as the picture to be processed for loading.

Illustratively, the enhanced picture A-2 of the thumbnail A-1 is loaded as the picture A to be processed and displayed to the user. It can be understood that displaying the to-be-processed picture a to the User means performing UI rendering on the to-be-processed picture a obtained in this step, and rendering the enhanced picture a-2 of the thumbnail a-1 as the to-be-processed picture a to a UI (User Interface) by the renderer.

By applying the embodiment shown in fig. 2 of the invention, the thumbnail of the picture to be processed is obtained from the network, and when the picture to be processed needs to be loaded, the thumbnail of the picture to be processed is enhanced by using the picture enhancement algorithm, so that the picture to be processed is obtained.

The process of loading the thumbnail of the picture to be processed can be realized by the following codes:

void magnifierAI(EncodedImage image)。

in order to solve the problem of the prior art, the embodiment of the invention also provides a second to-be-processed picture loading method.

Fig. 4 is a schematic diagram illustrating another method for loading a to-be-processed picture according to an embodiment of the present invention, as shown in fig. 4, in which an electronic device determines, according to a received picture loading request, whether or not picture enhancement is required to be performed on a picture corresponding to a to-be-processed picture a if the picture corresponding to the to-be-processed picture a is searched in a Bitmap cache, and if picture enhancement is not required, decodes the picture corresponding to the to-be-processed picture a and then renders a UI to display the UI to a user; if the picture is required to be enhanced and the picture is not enhanced, sending the picture corresponding to the picture A to be processed to the memory cache of the undecoded picture to enhance the picture corresponding to the picture A to be processed; if picture enhancement is needed and the picture is subjected to picture enhancement, the picture corresponding to the picture A to be processed is decoded and then UI rendering is carried out to display the picture to a user.

If the picture corresponding to the picture A to be processed does not exist in the Bitmap cache, sending a loading request to a memory cache of an undecoded picture, searching whether the picture corresponding to the picture A to be processed exists in the memory cache of the undecoded picture, judging whether picture enhancement needs to be carried out on the picture corresponding to the picture A to be processed or not if the picture enhancement does not need to be carried out, converting the picture corresponding to the picture A to be processed into a Bitmap picture, decoding the Bitmap picture, and carrying out UI rendering on the decoded Bitmap picture to display the Bitmap picture to a user; if the picture is required to be enhanced and the picture is not enhanced, enhancing the picture corresponding to the picture A to be processed; if picture enhancement is needed and the picture is subjected to picture enhancement, converting the picture corresponding to the picture A to be processed into a Bitmap picture, then decoding, storing the decoded Bitmap picture into a Bitmap cache, and then performing UI rendering and displaying to a user.

If the picture corresponding to the picture A to be processed exists in the hard disk cache, judging whether picture enhancement needs to be carried out on the picture corresponding to the picture A to be processed or not, if the picture enhancement does not need to be carried out, converting the picture corresponding to the picture A to be processed into a bitmap picture, decoding the bitmap picture, and carrying out UI rendering on the decoded bitmap picture and displaying the bitmap picture to a user; if the picture is required to be enhanced and the picture is not enhanced, enhancing the picture corresponding to the picture A to be processed; if the picture needs to be enhanced and the picture is enhanced, the picture A to be processed and the picture A are converted into a bitmap picture, decoding is carried out, and UI rendering is carried out on the decoded bitmap picture to display the bitmap picture to a user.

If the picture corresponding to the picture A to be processed does not exist in the hard disk cache, obtaining the picture corresponding to the picture A to be processed from the network; judging whether picture enhancement needs to be carried out on the picture corresponding to the picture A to be processed or not, if picture enhancement does not need to be carried out, storing the picture corresponding to the picture A to be processed into a hard disk cache and a memory cache, then converting the picture into a Bitmap picture, decoding the Bitmap picture, storing the decoded Bitmap picture into a Bitmap cache, and then carrying out UI rendering and displaying to a user; and if the picture enhancement is needed, carrying out the picture enhancement on the picture corresponding to the picture A to be processed.

Fig. 5 is a flowchart illustrating a second method for loading a to-be-processed picture according to an embodiment of the present invention, and as shown in fig. 5, on the basis of the embodiment shown in fig. 2 of the present invention, in the embodiment shown in fig. 5, before step S201, the following steps are added:

And searching a picture A-3 corresponding to the picture A to be processed in a memory cache of the electronic equipment according to the acquired loading instruction. If the picture a-3 corresponding to the picture a to be processed is not found in the memory cache, the step S206 is executed.

It can be understood that the picture a-3 corresponding to the picture a to be processed is a picture containing the same content. For example, if the picture a to be processed shows a lady yellow chang style coat, the picture a-3 corresponding to the picture a to be processed also contains a lady yellow chang style coat. In practical applications, the resolution of the picture a-3 corresponding to the picture a to be processed may be different from that of the picture a to be processed, for example, the resolution of the picture a-3 corresponding to the picture a to be processed may be greater than that of the picture a to be processed, the resolution of the picture a-3 corresponding to the picture a to be processed may be the same as that of the picture a to be processed, and the resolution of the picture a to be processed may be smaller than that of the picture a to be processed. Similarly, the size of the picture a-3 corresponding to the picture a to be processed may be different from the picture a to be processed, for example, the size of the picture a-3 corresponding to the picture a to be processed may be larger than the size of the picture a to be processed, the size of the picture a-3 corresponding to the picture a to be processed may be the same as the size of the picture a to be processed, and the size of the picture a to be processed may be smaller than the size of the picture a to be processed.

It should be noted that, when searching whether the picture corresponding to the picture a to be processed exists in the memory cache, the process may be completed by the memory cache module.

As shown in fig. 4, in step S205, if the picture a-3 corresponding to the picture a to be processed is found in the memory cache of the electronic device according to the obtained load instruction. If the picture A-3 corresponding to the picture A to be processed is found in the memory cache, the method further comprises the following steps:

it should be noted that the memory cache includes a Bitmap cache and a memory cache of an undecoded picture, which are collectively referred to as a memory cache in this step. In practical application, when the thumbnail corresponding to the picture a to be processed is searched in the memory cache of the electronic device, the searching may be performed according to the steps S2011-S2016.

S2011 (not shown in the figure): searching a picture corresponding to the picture to be processed in a Bitmap cache;

if the picture A-3 corresponding to the picture to be processed is not found in the Bitmap cache, executing step S2014; and if the picture A-3 corresponding to the picture to be processed is found in the Bitmap cache, executing the step S2012 or the step S2013.

And if the picture A-3 corresponding to the picture to be processed is found in the Bitmap cache, and the resolution of the picture A-3 corresponding to the picture to be processed is smaller than that of the picture A to be processed, and/or the size of the picture A-3 corresponding to the picture to be processed is smaller than that of the picture A to be processed, executing the step S2012.

And if the picture A-3 corresponding to the picture to be processed is found in the Bitmap cache, and the resolution of the picture A-3 corresponding to the picture to be processed is not less than the resolution of the picture A to be processed, and/or the size of the picture A-3 corresponding to the picture to be processed is not less than the size of the picture A to be processed, executing the step S2013. The process of searching the picture corresponding to the picture to be processed in the Bitmap cache can be realized by the following codes:

Bitmap newBitmapMemoryCacheGetProducer(ImageRequest request)。

s2012 (not shown in the figure): and taking the picture corresponding to the picture to be processed as the thumbnail of the picture to be processed, and sending the thumbnail of the picture to be processed and the loading instruction to the memory cache of the undecoded picture so as to enable the memory cache of the undecoded picture to execute the step S203.

And taking the picture A-3 corresponding to the picture to be processed as the thumbnail A-1 of the picture A to be processed, and sending the thumbnail A-1 and the loading instruction to the memory cache of the picture which is not decoded so as to enable the memory cache of the picture which is not decoded to carry out picture enhancement on the thumbnail A-1 of the picture A to be processed.

In practical application, after the application showing the picture a to be processed to the user is closed, the system of the electronic device may clear the Bitmap cache in the electronic device and the cache in the memory cache of the undecoded picture, so that the memory cache of the undecoded picture may send the thumbnail of the picture to be processed and the loading instruction to the hard disk cache, so as to perform picture enhancement on the thumbnail a-1 of the picture a to be processed in the hard disk cache.

It is understood that the execution process of step S203 in this step is identical to the execution process of step S203 described above, and is not described here again.

S2013 (not shown in the figure): and taking the picture corresponding to the picture to be processed as the thumbnail of the picture to be processed after the picture enhancement processing, and executing the step S204.

And taking the picture A-3 corresponding to the picture to be processed as a thumbnail of the picture A to be processed after the picture enhancement processing, and executing the step S204.

It is understood that the execution process of step S204 in this step is identical to the execution process of step S204, and is not described here again.

S2014 (not shown in the figure): according to the loading instruction, searching a picture corresponding to the picture to be processed in the memory cache of the undecoded picture;

it is to be understood that the load instruction acquired in this step is sent from the Bitmap cache in step S2011.

If the picture corresponding to the picture to be processed is found in the memory cache of the undecoded picture, and the resolution of the picture corresponding to the picture to be processed is smaller than that of the picture to be processed, and/or the size of the picture corresponding to the picture to be processed is smaller than that of the picture to be processed, the step S2015 is executed. If the picture corresponding to the picture to be processed is found in the memory cache of the undecoded picture, and the resolution of the picture corresponding to the picture to be processed is not less than the resolution of the picture to be processed, and/or the size of the picture corresponding to the picture to be processed is not less than the size of the picture to be processed, the step S2016 is executed.

And if the picture corresponding to the picture to be processed is not found in the memory cache of the undecoded picture, executing the step of finding the picture corresponding to the picture to be processed in the hard disk cache.

Searching the picture corresponding to the picture to be processed in the memory cache of the undecoded picture can be realized by the following codes:

ByteBuffer newEncodedMemoryCacheProducer(ImageRequest request)。

s2015 (not shown in the figure): and taking the picture corresponding to the picture to be processed as a thumbnail of the picture to be processed, and sending the thumbnail of the picture to be processed and the loading instruction to the hard disk cache so as to enable the hard disk cache to execute the step S203.

And taking the picture A-3 corresponding to the picture to be processed as a thumbnail A-1 of the picture A to be processed, and sending the thumbnail A-1 and the loading instruction to the hard disk cache so that the hard disk cache performs picture enhancement processing on the thumbnail A-1 of the picture A to be processed.

S2016 (not shown): and taking the picture corresponding to the picture to be processed as the thumbnail of the picture to be processed after the picture enhancement processing, and executing the step S204.

It should be noted that, when searching whether a picture corresponding to the picture a to be processed exists in the Bitmap cache and the memory cache of the undecoded picture, the process may be completed by the memory cache module, and the Bitmap cache and the memory cache of the undecoded picture belong to different parts in the memory cache, which may be collectively referred to as memory caches.

S206: and searching the picture corresponding to the picture to be processed in the hard disk cache according to the loading instruction.

Illustratively, according to the obtained loading instruction, a picture a-3 corresponding to the picture a to be processed is searched in a hard disk cache of the electronic device. If the picture corresponding to the picture to be processed is not found in the hard disk cache, executing the step S201; and if the picture corresponding to the picture to be processed is found in the hard disk cache, executing the step S207 or S208.

And if the picture A-3 corresponding to the picture to be processed is found in the hard disk cache, and the resolution of the picture A-3 corresponding to the picture to be processed is smaller than that of the picture A to be processed, and/or the size of the picture A-3 corresponding to the picture to be processed is smaller than that of the picture A to be processed, executing the step S207.

And if the picture A-3 corresponding to the picture to be processed is found in the hard disk cache, and the resolution of the picture A-3 corresponding to the picture to be processed is not less than the resolution of the picture A to be processed, and/or the size of the picture A-3 corresponding to the picture to be processed is not less than the size of the picture A to be processed, executing the step S208.

It can be understood that the picture a-3 corresponding to the picture a to be processed is a picture containing the same content. For example, if the picture a to be processed shows a lady yellow chang style coat, the picture a-3 corresponding to the picture a to be processed also contains a lady yellow chang style coat. In practical applications, the term "hard disk" may refer to: a mechanical hard disk, a solid state disk, an SD Card (Secure Digital Memory Card), a TF Card (Trans-flash Card), and the like can support a storage device that can not lose stored data after the device is powered off.

It should be noted that, when searching whether a picture corresponding to the picture a to be processed exists in the hard disk, the process may be completed by the hard disk cache module. The process of searching the picture corresponding to the picture to be processed in the hard disk cache can be realized by the following codes:

EncodedImage newDiskCacheProducer(ImageRequest request)。

s207: and taking the picture corresponding to the picture to be processed as a thumbnail of the picture to be processed, and executing the step S203.

For example, since the resolution of the picture a-3 corresponding to the picture to be processed is smaller than the resolution of the picture a to be processed, and/or the size of the picture a-3 corresponding to the picture to be processed is smaller than the size of the picture a to be processed, if the picture a-3 corresponding to the picture to be processed is directly displayed, the user experience may be reduced, and therefore, the picture a-3 corresponding to the picture to be processed is subjected to picture enhancement. It is necessary to take the picture a-3 corresponding to the picture to be processed as the thumbnail a-1 of the picture a to be processed and perform the step S203.

S208: and taking the picture corresponding to the picture to be processed as the thumbnail of the picture to be processed after the picture enhancement processing, and executing the step S204.

Illustratively, since the resolution of the picture a-3 corresponding to the picture to be processed is not less than the resolution of the picture a to be processed, and/or the size of the picture a-3 corresponding to the picture to be processed is not less than the size of the picture a to be processed, the picture a-3 corresponding to the picture to be processed is directly displayed, which does not reduce user experience, and therefore, the picture a-3 corresponding to the picture to be processed does not need to be enhanced. The picture a-3 corresponding to the picture to be processed may be directly taken as the thumbnail a-1 of the picture a to be processed after the image enhancement processing, and the step S204 is performed.

By applying the embodiment shown in fig. 5 of the present invention, before downloading the thumbnail of the picture to be processed, whether the picture corresponding to the picture to be processed exists is searched in the memory cache of the electronic device, and if the picture corresponding to the picture to be processed exists, the thumbnail of the picture to be processed does not need to be downloaded from the network, so that the traffic consumption of the user can be reduced. In addition, when the picture corresponding to the picture to be processed existing in the memory cache is used, the picture is directly read from the memory cache of the electronic equipment, and compared with the method for acquiring the thumbnail of the picture to be processed from the network, the method can reduce the reaction time, improve the speed of displaying the picture to be processed and further improve the user experience.
