The terminal 101 and the server 102 may be directly or indirectly connected through wired or wireless communication, and the embodiment of the present disclosure is not particularly limited thereto.
Based on the implementation environment shown in fig. 1, an embodiment of the present disclosure provides a method for displaying a screen saver picture, and referring to fig. 2, a flow of the method provided by the embodiment of the present disclosure includes:
201. and acquiring audio attribute information of a target audio file in which the target user is interested.
Wherein the audio attribute information includes at least one of a photo of a singer of the target audio file and lyrics of the target audio file.
202. And generating a screen saver picture according to the audio attribute information.
Based on the audio attribute information of the target audio file, the personalized screen saver picture can be generated by processing the audio attribute information.
203. And displaying the screen saver picture.
And based on the generated screen saver picture, the terminal switches the current display content into the screen saver picture. The generated screen saver pictures can be played in a certain sequence or randomly. By displaying the generated screen saver picture, the privacy information of the user can be protected, and the situation that the service life of the display screen is influenced by the aging of the display screen due to the fact that the terminal displays the same picture for a long time is avoided.
According to the method provided by the embodiment of the disclosure, the screen saver picture is generated and displayed based on the audio attribute information of the audio file which is interested by the user, so that the method for displaying the screen saver picture is provided. Because the audio files interested by different users are different, the audio files recommended to different users are also different, and the generated screen saver pictures are also different based on the audio attribute information of the recommended audio files, so that different user sides display different screen saver pictures, the individual requirements of different users are met, and the display effect is better.
Based on the implementation environment shown in fig. 1, an embodiment of the present disclosure provides a method for displaying a screen saver picture, taking a terminal to execute the embodiment of the present disclosure as an example, referring to fig. 3, where a flow of the method provided by the embodiment of the present disclosure includes:
301. and the terminal determines an audio file which is interested by the target user as a target audio file according to at least one item of user attribute information of the target user, operation behavior information in the audio playing application and local music information.
The terminal determines a target audio file which is interested by the target user according to at least one item of user attribute information of the target user, operation behavior information in the audio playing application and local music information, and the method comprises the following conditions:
in the first case, the terminal determines the target audio file which is interested by the target user according to the operation behavior information of the target user in the audio playing application.
The operation behaviors comprise clicking, collecting, downloading and other behaviors. The terminal counts the operation behavior of the target user in the audio playing application, obtains the operation behavior information of the target user in the audio playing application, and determines the target audio file interested by the target user according to the operation behavior information of the target user in the audio playing application. For example, if the number of times of playing the european and american song by the target user is counted, it may be determined that the song in which the target user is interested is the european and american song; for another example, if it is counted that the target user plays a song of zhou-jiron frequently, it may be determined that the song of interest to the target user is a song of zhou-jiron.
And in the second situation, the terminal determines the target audio file which is interested by the target user according to the user attribute information of the target user.
The user attribute information includes age, gender, native place, address, and the like. For example, if the target user is 10 years old, the song of interest to the target user may be determined to be a children song; for another example, if the target user's native place is inner Mongolia, the song of interest to the target user may be determined to be a grassland song.
And in the third situation, the terminal determines the target audio file which is interested by the target user according to the local music information of the target user.
The local music includes songs downloaded to the local, songs in a local playlist, and so on. The local music is usually a song of interest to the target user, and based on the local music information of the target user, the terminal may determine a target audio file of interest to the target user.
The above description is given by taking an example of determining a target audio file interested by a target user based on one of user attribute information of the target user, operation behavior information in an audio playing application, and local music information, and certainly, determining a target audio file interested by a target user based on two or three of user attribute information of the target user, operation behavior information in the audio playing application, and local music information may also be used, and the description is not repeated here.
It should be noted that, a target audio file that is interesting to the terminal is not fixed and unchanged, and as the running time of an audio playing application increases, the operation behavior information of a target user collected by the terminal is continuously rich, and a target audio file determined based on the operation behavior information may be updated, in order to accurately obtain the target audio file that is interesting to the target user, and to enrich a screen saver material for generating a screen saver picture and avoid the displayed screen saver picture from causing aesthetic fatigue to the user, in the embodiment of the present disclosure, the terminal updates the target audio file that is interesting at intervals (for example, one day, one week, and the like).
302. The terminal obtains audio attribute information of the target audio file.
Wherein the audio attribute information includes at least one of a photo of a singer of the target audio file, lyrics of the target audio file, and the like. Based on the determined target audio file, if the audio attribute information of the target audio file is locally stored, the terminal can obtain the audio attribute information of the target audio file from the local, and if the audio attribute information of the target audio file is not locally stored, the terminal obtains the audio attribute information of the target audio file from the server.
It should be noted that, the above is described by taking an example that the terminal determines a target audio file that is interested by the target user according to one of the user attribute information of the target user, the operation behavior information in the audio playing application, and the local music information, and then obtains the audio attribute information of the target audio file, of course, in order to reduce the processing pressure of the terminal, the above process may also be executed by the server, and after the server determines the target audio file, the server sends the audio attribute information of the target audio file to the terminal.
303. And the terminal generates a screen saver picture according to the audio attribute information.
The terminal generates the screen saver picture according to the audio attribute information, and the method comprises the following conditions:
in the first case, the terminal generates a screen saver picture according to the photo picture.
Based on the photo picture of the singer of the target audio file, the terminal can directly take the photo picture as a screen saver picture. However, considering that the sizes of the display screens of different terminals are different, in order to improve the display effect of the screen saver pictures, and to avoid the situation that the display screen has a blank area due to the fact that the size of the screen saver pictures is larger than the size of the screen saver pictures, and the displayed screen saver pictures are incomplete due to the fact that the size of the screen saver pictures is smaller than the size of the display screen, the embodiment of the disclosure adjusts the portrait picture to be the first picture with the same size as the size of the display screen as the screen saver picture according to the size of the display screen of the terminal.
And in the second situation, the terminal generates a screen saver picture according to the lyrics.
Based on the lyrics of the target audio file, the terminal converts the lyrics from a text form into a picture form, and further adjusts the picture according to the size of the display screen to generate a lyrics picture which has the same size as the display screen and contains the lyrics and is used as a screen saver picture.
And in the third situation, the terminal generates a screen saver picture according to the photo picture and the lyrics.
And the terminal adjusts the size of the photo picture according to the size of the display screen, adjusts the photo picture into a first picture with the same size as the display screen, and further draws the lyrics on the first picture.
For the method, the terminal needs to preset a display area for displaying the lyrics on the photo, and the size and the position of the display area are usually fixed, and the display area can be positioned at the lower right corner of the photo, the upper left corner of the photo, and the like.
Considering that the postures, actions, occupied areas and the like of singers on different portrait pictures are different, if all the portrait pictures are set in the same display area, the lyrics may block the human body area of the singers, so that the user has poor impression. In order to improve the display effect of the screen saver picture and improve the impression of a user, when the terminal generates the screen saver picture based on the photo picture and the lyrics, the display area of the lyrics can be determined according to the human body area on the photo picture. Specifically, the following method may be employed:
3031. the terminal adjusts the portrait picture to a second picture with a size smaller than that of the display screen and an aspect ratio the same as that of the display screen.
In order to improve the display effect of the screen saver picture generated based on the portrait picture and reduce the calculation amount when determining the display area corresponding to the target lyric, the terminal also adjusts the aspect ratio of the portrait picture according to the aspect ratio of the display screen and reduces the size of the portrait picture after the aspect ratio adjustment, so as to obtain a second picture which is smaller than the size of the display screen and has the same aspect ratio with the aspect ratio of the display screen.
3032. The terminal identifies a human body region on the second picture.
Based on the human body recognition algorithm, the terminal can recognize the human body area on the second picture by detecting the second picture. The human body recognition algorithm may be a body-pix algorithm, etc. Since the number of singers deducing the target audio file is at least one, when the number of singers is not less than two, the human body regions detected by the terminal are the human body regions of two singers.
3033. The terminal acquires the maximum display area on the second picture except the human body area.
The shape of the maximum display area may be a regular figure, such as a rectangle, a circle, a trapezoid, and the like, and may also be an irregular shape, and the shape of the maximum display area is not specifically limited in the embodiments of the present disclosure. Based on the identified human body region, the terminal removes the human body region on the second picture and acquires the largest display region from the remaining regions.
3034. And the terminal determines a corresponding display area of the lyrics on the second picture according to the area of the lyrics occupied by the lyrics and the maximum display area.
In the embodiment of the disclosure, the terminal may preset information such as a font, a word size, a word spacing, a line spacing, and the like of the lyrics, and based on the set information, the terminal may calculate a lyric area occupied by the lyrics, and then determine a display area corresponding to the lyrics on the second picture by comparing the lyric area occupied by the lyrics with the maximum display area. Specifically, the following method may be employed:
30341. the terminal acquires a reduction ratio for reducing the size of the display screen to the size of the second picture.
Since the second picture is not a screen saver picture to be displayed by the final terminal, but an intermediate picture obtained by reducing the photo picture in order to reduce the calculation amount, the size of the second picture is smaller than that of the display screen, and if the second picture is directly compared with the area of the lyrics, whether the target lyrics can be completely drawn into the display area cannot be accurately known, therefore, the reduction ratio for reducing the size of the display screen to the size of the second picture needs to be obtained, the area of the lyrics is reduced proportionally based on the reduction ratio, and then the reduced area of the lyrics is compared with the second picture. When the reduction scale is obtained, the ratio of the length of the display screen to the length of the second picture can be used as the reduction scale based on the size of the display screen and the size of the second picture, and the ratio of the width of the display screen to the width of the second picture can also be used as the reduction scale.
30342. And the terminal reduces the area of the lyrics according to the reduction ratio to obtain the reduced area of the lyrics.
And based on the determined reduction ratio, the terminal reduces the area of the lyrics in an equal proportion according to the reduction ratio to obtain the reduced area of the lyrics.
30343. And the terminal determines a corresponding display area of the lyrics on the second picture according to the reduced area of the lyrics and the maximum display area.
And the terminal compares the reduced area of the lyrics with the maximum display area and determines the corresponding display area of the lyrics on the second picture according to the comparison result.
In a possible implementation manner, when the area of the lyrics after being reduced is smaller than the maximum display area, it is indicated that the lyrics can be completely drawn into the maximum display area, and the terminal takes the maximum display area as a display area corresponding to the lyrics on the second picture.
In another possible implementation manner, when the area of the lyrics after being reduced is larger than the maximum display area, it indicates that the lyrics cannot be completely drawn into the maximum display area, and the terminal needs to re-determine the display area corresponding to the lyrics on the second picture. The determination process includes the steps of:
in the first step, the terminal determines the eye area on the second picture.
The terminal detects the human body region on the second picture, and recognizes a human eye region from the human body region, wherein the human eye region can be located at the upper left corner, the upper right corner, the lower left corner, the lower right corner and the like of the second picture.
And secondly, the terminal determines the area with the specified size corresponding to the human eye area in the reverse direction as the display area corresponding to the lyrics on the second picture.
And the terminal determines the area with the specified size corresponding to the human eye area in the reverse direction as the corresponding display area of the lyrics on the second picture according to the position relation between the human eye area and the second picture. The regions corresponding to the opposite directions are two regions with opposite directions, for example, the human eye region is located at the upper left corner of the second picture, and the terminal can determine the region with the size specified by the lower right corner on the second picture as the display region corresponding to the lyrics on the second picture; for another example, if the human eye region is located in the upper right corner of the second picture, the region with the size specified by the lower left corner on the second picture is determined as the display region corresponding to the lyrics on the second picture, and so on. The specified size can be an area which occupies one fourth, one fifth and the like of the area of the second picture, and the specified size is larger than the maximum display area, so that the lyrics can be completely drawn into the area with the specified size.
3035. And the terminal adjusts the size of the second picture into the first picture with the same size as the display screen.
