Summary of The Invention
The inventor finds that in the existing control center operation interface, when a cover picture needs to be displayed, the cover picture with lower resolution is required to be directly stretched and displayed, so that the picture display quality is reduced, and the cover picture becomes fuzzy; or the cover picture is replaced with a unified picture, which reduces the recognition of the content being played.
In view of this, in the embodiment of the present invention, for an original cover picture whose resolution does not meet a resolution threshold, a target cover picture meeting a display quality requirement is synthesized by using the original cover picture, so that while the display quality of the cover picture is ensured, a certain degree of identification can be ensured, and a user can determine the current playing content according to the cover picture.
Having described the general principles of the invention, various non-limiting embodiments of the invention are described in detail below.
Application scene overview
Reference is first made to fig. 3, which is a schematic diagram illustrating an application scenario implemented by the embodiment of the present invention. Comprising a user device 11 and a server 12. The user equipment 11 may be installed with clients, such as a bean-paste reading client, an internet-accessible cloud reading client, an internet-accessible caricature client, an internet-accessible cloud music client, and the like. The user 10 may send a resource access request to the server 12 through a client in the user device 11 to access the electronic resource provided by the server 12, for example, the user 10 sends an e-book listening request to the server 12 through a client in the user device 11, and the server 12 provides an e-book listening service to the user in the form of audio in response to the request of the user device 11. In the process of listening to the electronic book, when the user equipment 11 enters the screen locking state, the operation interface of the control center is displayed, and the cover picture in the operation interface can be a picture processed by using the picture processing method provided by the embodiment of the invention.
Wherein, the user device 11 and the server 12 can be connected by communication network, which can be local area network, wide area network, etc. The user device 11 may be a mobile phone, a tablet computer, a notebook computer, a personal computer, etc., and the server 12 may be any server device capable of providing electronic resource content in audio form.
Exemplary method
A method for picture processing according to an exemplary embodiment of the present invention is described below with reference to fig. 4-7 in conjunction with the application scenario of fig. 3. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.
Fig. 4 is a schematic diagram illustrating an implementation flow of the image processing method according to the embodiment of the present invention. It may be performed by the user equipment 11, more specifically by a client installed on the user equipment 11, or by the server 12, or by the user equipment 11 for part of the steps, and by the server 12 for part of the steps.
Specifically, the following steps may be included:
and S41, determining a resolution threshold value meeting the picture display quality requirement.
In this step, the server or the client can judge the resolution threshold value which can meet the requirement of the picture display quality according to the size of the picture displayed on the operation interface of the control center, and the cover picture which is lower than the resolution threshold value cannot be clearly displayed when being displayed. Wherein each picture size may correspond to a resolution threshold. In the case that the corresponding resolution of the picture of the corresponding picture size is lower than the threshold, if the stretching operation on the picture is changed into the picture size displayed by the control center operation interface, the picture can be over-blurred. Alternatively, the resolution threshold may include a case where the picture cannot be clearly displayed even without performing a stretching operation on the picture.
S42, screening out original cover pictures lower than the resolution threshold according to the resolution threshold, wherein the original cover pictures are used for synthesizing target cover pictures meeting the preset display quality requirement.
In the step, the server screens out the original cover pictures which are lower than the resolution threshold, and the screened original cover pictures cannot be clearly displayed when the original cover pictures are displayed on the operation interface of the control center.
In the embodiment of the invention, aiming at the screened original cover pictures, the original cover pictures are utilized to synthesize the target cover pictures meeting the display quality requirement. In specific implementation, the original cover picture and the preset picture can be spliced to obtain the target cover picture for each screened original cover picture. The preset pictures can be selected according to actual requirements, for example, the preset pictures can be transparent pictures, if the preset pictures are transparent pictures, the preset pictures are spliced with the original cover pictures to obtain the target cover pictures, the transparent picture is invisible for users, the users can only see the original cover pictures, and the spliced target cover pictures are as shown in fig. 5 a. The preset picture may also be a picture including a brand logo, in this case, the target cover picture obtained after splicing is shown in fig. 5b, and certainly, in the specific implementation, other pictures may also be used to be spliced with the original cover picture, which is not listed in the embodiment of the present invention.
In specific implementation, the preset picture and the original cover picture can be spliced according to the flow shown in fig. 6:
and S61, adjusting the size of the original cover picture according to the resolution threshold value until the adjusted display quality of the original cover picture meets the preset display quality requirement.
In this step, the size of the original cover picture is adjusted according to the resolution threshold determined in step S41, specifically, the original cover picture may be scaled down in equal proportion, and the resolution of the scaled-down original cover picture is not lower than the resolution threshold, so that the original cover picture can be clearly displayed. Or, the original cover picture is properly stretched in equal proportion, so that the display requirement is met. Wherein the second case is for the following cases: the original cover picture is smaller in size but higher in resolution so that the original cover picture can be stretched.
And S62, overlapping the adjusted original cover picture on the preset picture to obtain a target cover picture.
In the step, the adjusted original cover picture is superposed on a preset picture to obtain a target cover picture. Therefore, when the control center operation interface needs to display the cover picture, the target cover picture can be displayed.
In step S62, the steps may be superimposed according to the flow shown in fig. 7:
and S71, respectively determining the left and right width values of the original cover picture spliced to the preset picture according to the width value of the preset picture.
The size of the preset picture can be determined according to the display requirement of the control center. Assuming that the size of the preset image is 120 × 100, that is, the width value of the preset image is 120 pixels, the height value of the preset image is 100 pixels, and the size of the adjusted original cover image is 75 × 50, preferably, in order to ensure that the spliced target cover image is neat and beautiful, the original cover image and the preset image can be displayed in the middle after being spliced. Thus, the left and right width values of the original cover picture spliced to the preset picture are 22.5 pixels respectively.
And S72, respectively determining the upper and lower height values of the original cover picture spliced to the preset picture according to the height value of the preset picture.
Similar to step S71, in this step, it can be determined that the height values of the original cover picture spliced to the preset picture are 25 pixels each.
And S73, determining the position information of the original cover picture spliced to the preset picture according to the left-right width value and the upper-lower height value.
In this step, according to the left-right width value and the up-down height value after the original cover picture determined in steps S71 and S72 is spliced to the preset picture, the position information after the original cover picture is spliced to the preset picture can be determined, and in specific implementation, the position information can be described by using a pixel abscissa and a pixel ordinate.
Specifically, taking the upper left corner of the preset picture as the origin of coordinates, according to the width value and the height value determined in steps S71 and S72, it can be determined that the coordinates of the four vertices of the original cover picture after being spliced to the preset picture are respectively: coordinates of the upper left corner: (22.5, 25), lower left corner coordinates (22.5, 75), upper right corner coordinates (97.5,25), lower right corner coordinates (97.5, 75).
And S74, overlapping the adjusted original cover picture to the corresponding position determined according to the position information to obtain the target cover picture.
It should be noted that the image processing method provided by the embodiment of the present invention can be implemented by the server alone, that is, the server sends the processed target cover image to the client for display by the client, or implemented by the server and the client in a matching manner, in this implementation, the server screens out the original cover image lower than the resolution threshold and notifies the client, the client automatically synthesizes the original cover image and the preset image, and displays the synthesized target cover image on the operation interface of the control center; in specific implementation, the client may also implement the method separately, which is not limited in the embodiment of the present invention.
In the image processing method provided by the embodiment of the invention, the original cover image with the resolution lower than the determined resolution threshold is adjusted to the size meeting the display quality requirement and then is superposed on a preset image, such as a transparent image or a brand LOGO image, so that the image quality displayed on the operation interface of the control center can be ensured, the displayed image has certain recognition degree on the playing content, and the user experience is improved.
