It should be noted that the scene diagram of image processing shown in fig. 1 is only an example, and the image processing scene described in the embodiment of the present application is for more clearly illustrating the technical solution of the present application, and does not constitute a limitation on the technical solution provided by the present application. As will be appreciated by those skilled in the art, with the evolution of image processing and the advent of new business scenarios, the solution provided by the present application is equally applicable to similar technical problems.
Based on the above-described implementation scenarios, detailed descriptions will be given below.
The embodiments of the present application will be described from the perspective of an image processing apparatus, which may be integrated in a computer device. The Computer device may be a terminal or a server, and the terminal may be a mobile phone, a tablet Computer, a notebook Computer, a smart television, a wearable smart device, a Personal Computer (PC), or the like. As shown in fig. 2, a schematic flow chart of an image processing method provided by the present application is shown, where the method includes:
and step 101, acquiring a target grid corresponding to the poster image in a grid display page of the TV terminal.
In the embodiment of the present application, the content display of the TV end is displayed in a grid layout manner, that is, a display area of a display screen of the TV end is divided into a plurality of grid cells, and each grid cell is used as an individual part to display the content. The different grid cells may be the same size or different sizes. For each video file to be played, a poster image corresponding to the video file can be displayed on a display page of the TV end, and the poster image can be displayed in any grid unit.
In the related art, each poster image of a video to be played is compressed and stored according to a uniform format, and when the poster image is rendered on a display page of a TV end, the compressed poster image needs to be acquired, and then adaptive adjustment is performed according to the resolution of a grid unit which is correspondingly displayed, so that the poster image is completely displayed in the corresponding grid unit. Since the resolution of the poster image needs to be adapted to the grid cells before rendering, rendering efficiency is low, fluency of the TV page is reduced, and viewing experience of the user is affected. In contrast, the image processing method provided by the application can be used for preprocessing the image, so that adaptation is not needed when the image is rendered, rendering efficiency is improved, fluency of a TV page is improved, and watching experience of a user is improved. The image processing method provided by the present application is described in further detail below.
Since the gridding layout scheme for displaying content in a TV page is generally fixed, a target grid for displaying a poster image can be determined in a TV-end grid display page. For example, in general, if the poster image is a poster image corresponding to a video which is newly released and has the highest popularity, the target grid corresponding to the poster image may be a grid with the largest size at the upper left corner of the screen.
The display resolution may also be referred to as pixel resolution, which is simply referred to as resolution, and it refers to the number of pixels that can be displayed by the display, and usually multiplies the number of pixels per row by the number of pixels per column. The display resolution of the target grid is the number of pixels displayed in the target grid area, which can be expressed by multiplying the number of pixels per row by the number of pixels per column.
And 103, carrying out geometric compression on the poster image according to the display resolution to obtain a transition image.
In the embodiment of the application, after the display resolution of the target grid corresponding to the poster image is determined, the poster image can be adapted in advance according to the display resolution of the target grid, that is, the poster image is compressed according to the display resolution of the target grid as an image resolution compression index, so that a transition image is obtained. Specifically, for example, if the display resolution of the target grid is 200 × 300 and the image resolution of the poster image is 800 × 1200, the image resolution of the poster image may be first compressed to 200 × 300, resulting in a transition image.
And step 104, compressing the transition image to obtain a target image.
After the poster image is compressed in an equal ratio to obtain a transition image, the transition image can be further compressed to obtain a target image. In this way, the data amount of the poster image can be further reduced on the basis that the data amount of the poster is reduced by the geometric compression. The transmission speed of the image is improved, and the consumption of broadband resources and the consumption of server storage resources are reduced.
In some embodiments, the transition image is compressed, and in particular, the transition image may be compressed losslessly. Thus, the TV terminal can be made to restore the original data completely without causing any distortion when displaying the poster image.
According to the description, the image processing method provided by the application obtains the corresponding target grid of the poster image in the grid display page of the TV end; determining a display resolution of the target grid; performing equal-ratio compression on the poster image according to the display resolution to obtain a transition image; and compressing the transition image to obtain a target image. Therefore, the poster images are subjected to advanced geometric compression and lossless compression according to the display resolution of the TV end grids, so that the sizes of the poster images do not need to be adapted when the poster images are rendered, and the rendering efficiency of the poster images is improved.
Accordingly, the embodiment of the present application will further describe in detail the image processing method provided by the present application from the perspective of a computer device, where the computer device may be a terminal or a server. As shown in fig. 3, another schematic flow chart of the image processing method provided in the present application is shown, where the method includes:
The computer device can receive the grid generation instruction sent by the management background and also can receive the grid generation instruction sent by the TV terminal. The grid generation instruction includes specific grid setting data, and the grid setting data includes display position data of each grid on a TV-side display page and display resolution data of each grid. According to the data, a gridding layout for carrying out grid display on the TV end can be generated, and the gridding layout corresponds to the display position and the display resolution of each grid on the display interface of the TV end.
In some embodiments, receiving input grid generation instructions includes:
1. acquiring dragging operation data input by a user and received by a TV end;
2. and generating a grid generating instruction according to the operation data.
In the embodiment of the application, the computer device can receive the drag operation data from the TV terminal. Here, the drag operation data may be operation data input by the user on a display page of the TV terminal. Wherein, in the display page of the TV end, the user can customize the grid layout. Specifically, the user-defined design data of the grid layout in the TV end display page can be determined by receiving touch data of the user on the TV screen, sensing gesture data of the user or receiving adjustment data input by the user through a remote controller. Specifically, when the user determines the user-defined design data by receiving the touch data of the user on the TV screen, the drag operation data input by the user may be received, where the drag operation data may include dragging the entire grid and dragging the edge of the grid, that is, the operation may change the position of the grid, and may also change the display resolution of the grid.
After receiving user-defined design data (including the drag operation data) input by a user, the TV end may obtain the drag operation data received by the TV end, and then generate a mesh generation instruction according to the drag operation data. And the computer equipment generates a gridding layout or updates the gridding layout according to the instruction so as to display by adopting the updated gridding layout in the subsequent display.
The TV often loads a plurality of different video playing applications, and the different video playing applications also enjoy different copyrights for different video resources. For any one target video playing application, the copyrighted movie and television resources store poster images corresponding to the movie and television resources in corresponding servers; for newly copyrighted video resources, video data with poster images needs to be uploaded to a server corresponding to an application program. In the embodiment of the application, a user can upload video data of a newly copyrighted video resource to computer equipment, and the computer equipment receives the uploaded video data and extracts a poster image corresponding to the video data from the video data.
For different video resources, different display strategies are available on the display page of the video playing application program. For example, the latest and hottest movie and television resources are generally displayed at the most prominent position, for example, in the grid with the largest top left corner of the display area; for older movie assets that are less hot, they are typically displayed at a slightly marginal position, such as in the lower grid of the bottom row of the display area.
After the computer equipment acquires the poster image, the corresponding target grid of the poster image in the TV end grid display page is determined according to the heat of the movie and television resource corresponding to the poster image and the corresponding display strategy. Specifically, for example, the target grid is the grid with the largest upper left corner of the display page of the TV end.
At step 204, the computer device determines a display resolution of the target grid.
After determining that the poster image corresponds to the target grid, the computer device may further obtain display resolution data corresponding to the target grid. After the gridding layout is performed on the TV end display, the display resolution of each grid in the TV end display page is determined, and the display resolution corresponding to each grid can be determined and stored according to detailed layout data of the gridding layout. Thus, after the target grid corresponding to the poster image is determined, the display resolution of the target grid can be directly obtained from the stored display resolution data of each grid.
And step 205, the computer device performs geometric compression on the poster image according to the display resolution to obtain a transition image.
The gridding layout of each video playing application displayed at the TV end is generally fixed and has less variation. Therefore, when the video resource is received, the poster image of the video resource can be compressed in an equal ratio mode according to the display resolution of the target grid correspondingly displayed by the video resource, and the transition image corresponding to the poster image is obtained. Therefore, when the poster image is displayed, resolution adaptation to the poster image subjected to lossless compression is not needed according to the display resolution of the grid, and the rendering efficiency of the poster image is improved.
Specifically, the method for performing geometric compression on the poster image according to the display resolution to obtain the transition image comprises the following steps:
1. determining grid pixel data of a target grid according to the display resolution;
2. and adjusting the pixels of the poster image based on the grid pixel data to obtain a transition image.
After the display resolution of the target grid is obtained, the real pixels corresponding to the target grid can be calculated, and then the real pixels of the target grid are compared with the poster pixels. If the length and width of the poster pixels are larger than the real pixels of the grid, an equal-ratio compression program can be called to perform equal-ratio compression on the poster image, namely, the pixels of the poster image are adjusted, so that the pixels of the poster image are the same as the real pixels of the target grid, and a transition image is obtained.
And step 206, carrying out lossless compression on the transition image by the computer equipment to obtain a target image.
And the computer equipment performs geometric compression on the poster image according to the display resolution of the target grid to obtain a transition image. The transition image can be further subjected to lossless compression, the resolution of the poster image is not adjusted any more by the lossless compression, and only the data size of the poster image is further reduced. Therefore, the consumption of the storage resource of the computer equipment can be reduced, and the consumption of the broadband resource in the image transmission process can also be reduced.
And step 207, carrying out format detection on the target image by the computer equipment, and converting the format of the target image into a webp format.
After the poster image is subjected to geometric compression and lossless compression, whether the image format of the obtained target image is the webp format can be further detected. The webp format is a picture file format that provides both lossy compression and lossless compression (reversible compression), and can greatly reduce the file size while ensuring the same picture quality. The format of the target image is converted into the webp format, so that the data volume of the poster image can be further reduced, the data storage pressure of a server is further reduced, and the broadband resource consumption of data transmission is reduced. Therefore, the image transmission efficiency can be improved, the page switching of the TV end is smoother, and the watching experience of a user is improved.
In some embodiments, the method further comprises:
and uploading the format-converted target image to an oss server.
Among them, the object storage server (oss) is a distributed object storage server, and provides an object storage service in the form of a key-value pair. Since each video playing application has a huge amount of movie resources, each movie resource has its corresponding poster image. The storage of these resources can occupy a large amount of storage resources of the server, thereby causing a reduction in the processing efficiency of the video playback application. Therefore, the video resource data and the poster image data corresponding to the video resource data are uploaded to the oss server for storage, so that the storage pressure of the server of the video playing application program can be released, and the data processing efficiency of the video playing application program is improved.
As can be seen from the above description, the image processing method provided in the embodiment of the present application obtains a target grid corresponding to a poster image in a grid display page on a TV end; determining a display resolution of the target grid; performing equal-ratio compression on the poster image according to the display resolution to obtain a transition image; and carrying out lossless compression on the transition image to obtain a target image. Therefore, the poster images are subjected to advanced geometric compression and lossless compression according to the display resolution of the TV end grids, so that the sizes of the poster images do not need to be adapted when the poster images are rendered, and the rendering efficiency of the poster images is improved. Furthermore, the image processing method provided by the application performs two-step image compression, and converts the image format into the webp format, so that the data size of the poster image is greatly reduced, the data storage capacity in the server is reduced, the broadband resource consumption in the image transmission process is also reduced, and the storage cost and the flow cost are saved.
