Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a first embodiment of a method for pushing and displaying pictures provided by an embodiment of the present invention. Wherein, as shown in Figure 3, the method for pushing and displaying pictures may include the following steps:

S301. The server receives a lock screen picture download request sent by a terminal, where the lock screen picture download request is used for the terminal to request the server to download a first lock screen picture.

Wherein, the lock screen picture refers to the picture of the lock screen magazine pushed by the server displayed on the lock screen interface of the terminal.

In the embodiment of the present invention, when the server pushes the lock screen magazine, the terminal first obtains the lock screen picture list of the lock screen magazine, and then when the terminal browses the lock screen picture, it sends a lock screen picture download request to the server to request Download the first lock screen picture on this lock screen picture list.

S302. Obtain the current network status of the terminal.

Wherein, the current network state of the terminal refers to a state of the current network environment of the terminal.

In the embodiment of the present invention, the network status of the terminal includes parameters such as network type and network speed.

S301. Return a second lock screen picture with a resolution and a compression ratio corresponding to the current network state according to the current network state of the terminal in response to the lock screen picture download request, the second lock screen picture is the same as the Lock screen pictures with the same content as the first lock screen picture but with different resolutions and/or compression ratios.

Among them, the resolution refers to the amount of information stored in the image, and is a parameter used to indicate how many pixels are in the image per inch. It can be understood that the higher the resolution, the greater the clarity of the image display, but at the same time The size of the image will be larger, so that when the server returns the picture to the terminal, the download size of the picture will be larger when the terminal receives the picture. On the contrary, the lower the resolution, the smaller the clarity of the image display, but At the same time, the size of the image will be smaller, so that when the server returns the picture to the terminal, the download size of the picture when the terminal receives the picture will be smaller.

Among them, the compression ratio refers to a ratio value when the server compresses the picture, and the ratio value is a value less than 1. It can be understood that the smaller the compression ratio of the image, the smaller the size of the image, so that when the server returns the When the picture is sent to the terminal, the size of the download when the terminal receives the picture will be larger, otherwise, the size of the image will be larger, so that when the server returns the picture to the terminal, the download size when the terminal receives the picture will be smaller smaller.

In the embodiment of the present invention, since the first lock screen picture and the second lock screen picture are lock screen pictures with different resolutions and compression ratios generated after processing the same lock screen picture when the server uploads pictures, the first lock screen picture The content of the image represented by the screen picture and the second lock screen picture is the same, but if displayed on the terminal side, it will be expressed as a different definition.

It can be seen that in the solution of this embodiment, the server receives the lock screen picture download request sent by the terminal, and the lock screen picture download request is used for the terminal to request the server to download the first lock screen picture; The current network state of the terminal; according to the current network state of the terminal, return the second lock screen picture with the resolution and compression ratio corresponding to the current network state in response to the lock screen picture download request, and the second lock screen picture It is a lock screen picture with the same content as the first lock screen picture but with a different resolution and/or compression ratio. According to the current network status of the terminal, lock screen pictures with different resolutions and compression ratios are set for different terminals to download and display, so as to meet different users' needs for lock screen pictures and improve user experience.

Furthermore, since the server configures lock screen pictures with different resolutions and compression ratios for the terminal according to the network status of the terminal, the server can also actively implement strict policy control on the lock screen pictures downloaded by the terminal to prevent large loss of picture information , to ensure that the image distortion of the response is within the allowable range.

Optionally, in some possible implementation manners of the present invention, before the server receives the lock screen picture download request sent by the terminal, the method further includes:

performing resolution processing on the lock screen picture to obtain M lock screen pictures of M different resolutions of the lock screen picture;

Compress each of the M lock screen pictures by N compression ratios to obtain M*N lock screen pictures.

Wherein, the M is a positive integer, and the N is a positive integer.

For example, in one example of the present invention, when the server receives the lock screen picture to be released and uploads it to the server, the server performs different resolutions and different compression comparisons on the lock screen picture, thereby generating different resolutions and different compression ratios. Lock screen pictures with different compression ratios, and then the server saves the lock screen pictures in the server.

Furthermore, the server associates different lock screen pictures with different network states of the terminal, so that after detecting the lock screen state of the terminal, the server can send the lock screen picture corresponding to its network state to the terminal according to the corresponding relationship.

It can be understood that by processing the lock screen picture uploaded to the server with different resolutions and different compression ratios, lock screen pictures with different resolutions and compression ratios can be generated, and the content of the lock screen picture is the same as the original uploaded The picture is the same, only the size is different, resulting in different clarity.

Referring to FIG. 4 , FIG. 4 is a schematic flowchart of a second embodiment of a method for pushing and displaying pictures provided by an embodiment of the present invention. Wherein, as shown in Figure 4, the picture push and display method may include the following steps:

S401. The terminal sends a first lock screen picture download request to a server, where the lock screen picture download request is used for the terminal to request the server to download the first lock screen picture.

S402. Receive a second lock screen picture with a resolution corresponding to the current network state of the terminal and a compression ratio returned by the server in response to the first lock screen picture download request, where the second lock screen picture is the same as The first lock screen pictures have the same content but different resolutions and/or compression ratios.

In the embodiment of the present invention, since the server can return lock screen pictures with different resolutions and compression ratios according to the network status of the terminal, when the terminal requests the first lock screen picture from the server, it will receive the same content returned by the server. But due to the resolution and compression compare the second lock screen picture differently.

S403. Display the second lock screen picture on the display screen of the terminal.

It can be seen that in the solution of this embodiment, the terminal sends a first lock screen picture download request to the server, and the lock screen picture download request is used for the terminal to request the server to download the first lock screen picture; receiving the The second lock screen picture with the resolution and compression ratio corresponding to the current network state of the terminal returned by the server in response to the first lock screen picture download request, the second lock screen picture is the same as the first lock screen picture Screen lock pictures with the same content but with different resolutions and/or compression ratios; and displaying the second lock screen picture on the display screen of the terminal. By receiving different lock screen pictures returned by the server according to the terminal network status, the terminal can receive and display clearer lock screen pictures when the network status is good, and receive relatively unclear lock screen pictures when the network status is not good. The lock screen picture ensures the receiving speed, so that the lock screen picture will not flicker when displayed.

Furthermore, since the server configures lock screen pictures with different resolutions and compression ratios for the terminal according to the network status of the terminal, the server can also actively implement strict policy control on the lock screen pictures downloaded by the terminal to prevent large loss of picture information , to ensure that the image distortion of the response is within the allowable range.

Optionally, in some possible implementation manners of the present invention, the displaying the second lock screen picture on the display screen of the terminal includes:

During the downloading process of the second lock screen picture, if the terminal receives a preset operation command from the user, compress the second lock screen picture according to a preset compression ratio to obtain a third lock screen picture;

displaying the third lock screen picture on the display screen of the terminal.

Wherein, the third lock screen picture is a lock screen picture with the same content as the second lock screen picture but with different compression ratios, thus having different picture sizes.

Optionally, the user's preset operation instructions are some quick operation instructions of the user, such as fast sliding, frequent switching, large loading and other operation instructions, so that when the terminal receives the operation instruction, due to the high demand for display speed, Therefore, it is necessary to load pictures faster, so at this time, under the same network environment, you can choose to reduce the size of the downloaded pictures first, that is, compress the lock screen picture, so that the requested lock screen picture can be displayed on the terminal in time.

It can be understood that by further compressing the lock screen picture when the terminal loads the lock screen picture, it is ensured that the terminal displays the lock screen picture in time when the terminal receives some quick operations from users.

Optionally, in some possible implementation manners of the present invention, after displaying the third lock screen picture on the display screen of the terminal, the method further includes:

After the download of the second lock screen picture is completed, the second lock screen picture is displayed on the display screen of the terminal to replace the third lock screen picture.

It can be understood that since the second lock screen picture is a lock screen picture obtained by compressing the picture in order to quickly display the lock screen picture during the loading process when the terminal receives some quick operation instructions, the lock screen picture is due to After compression, the image clarity is lost, so after the download of the second lock screen picture is completed, the second lock screen picture can be loaded to replace the original third lock screen picture, so that the terminal can receive the quick operation The picture is displayed in time when the command is issued, and the quality of the displayed lock screen picture can be guaranteed.

Optionally, in some possible implementations of the present invention, the method further includes:

If the current network state of the terminal changes, the terminal sends a second lock screen picture download request to the server, and the second lock screen picture download request is used for the terminal to request the server to download a fourth lock screen picture Screen picture, the fourth lock screen picture is a lock screen picture with a resolution corresponding to the current network state of the terminal and a compression ratio, the fourth lock screen picture is the same as the first lock screen picture, but Lock screen images with different resolutions and/or compression ratios.

For example, when the terminal changes from an outdoor mobile network environment to a wireless wifi network environment, because the terminal is in an outdoor mobile network environment, firstly, due to poor network quality, and secondly, in order to save download costs, the server in this network state is The terminal is configured with a low-resolution and high-compression lock screen picture, and when the terminal is converted to indoor wireless wifi, because the network speed becomes faster, and wireless wifi generally provides unlimited traffic download, so the terminal is at this time Under the change of the network environment, the terminal is re-triggered to request a new fourth lock screen picture from the server.

It can be understood that by re-requesting to download the lock screen picture when the network status of the terminal changes, so that after the terminal changes from a poor network environment to a better network environment, it can request a clearer picture that matches the network status again. Display lock screen pictures with effects to improve user experience.
