Referring to fig. 1, fig. 1 is a flowchart illustrating an image processing method according to an embodiment of the present disclosure.
As shown in fig. 1, the image processing method includes steps S101 to S103.
Step S101, a target image to be processed is obtained, and whether the data volume of the target image is larger than or equal to a preset data volume threshold value or not is determined.
When an image with a large data size needs to be transmitted or displayed, a target image to be transmitted or displayed is usually compressed to reduce the operation data size of the terminal device.
The target image can be prestored in a memory of the terminal device, so that the target image can be directly acquired by the terminal device. The target image may also be stored in a database or an external device, and the terminal device acquires the target image from the database or the external device and determines the data amount of the target image. It should be noted that the target image may be one or more, the terminal device may be a mobile phone, a tablet computer, a notebook computer, etc., the database includes a local database and a cloud database, and the external device may be a plug-in hard disk, a secure digital card, a flash memory card, etc. equipped with the terminal device.
Specifically, a target image to be processed is selected through a control page, a menu bar or a popup of the terminal device; through the selection operation, the terminal equipment generates a corresponding image processing task; and acquiring a target image based on the execution instruction and the image identifier in the image processing task. The image identifier uniquely corresponds to the target image, and it should be noted that the selection operation may be a single selection of the target image or a batch selection.
In an embodiment, a plurality of candidate images are obtained by shooting through a camera installed on the terminal device, and the candidate images are stored in an image library of the terminal device, and a user can select one or more candidate images from the image library as a target image to be processed. It can be understood that the candidate image may also be obtained by shooting with a camera of another device, and then the candidate image obtained by shooting is sent to the terminal device, which is not specifically limited in this application.
After the target image is acquired, it is determined whether the data amount of the target image is greater than or equal to a preset data amount threshold. It should be noted that the preset data amount threshold may be set according to an actual situation, which is not specifically limited in this application, and optionally, the data amount threshold is 5M. By confirming the target image with larger data quantity and further processing the target image with larger data quantity, the method can be more suitable for display on terminal equipment or other equipment, and brings better display effect.
In one embodiment, when a user requests to access a webpage on a terminal device, the terminal device generates a webpage access request and sends the webpage access request to a server, wherein the webpage comprises at least one image. And after receiving the image acquisition request, the server sends the data of the webpage to the terminal equipment so that the terminal equipment can load and display the webpage. When the terminal device loads the image in the web page, it needs to determine whether the data volume of the image is greater than or equal to a preset data volume threshold value, so as to further process the image with a larger data volume. Specifically, the further processing may include performing resolution compression, quality compression and scaling on the image to adapt the image to the presentation on the terminal device, thereby improving the presentation effect on the terminal device.
Step S102, if the data volume of the target image is larger than or equal to a preset data volume threshold, acquiring a resolution parameter, a compression quality parameter and an image size parameter of the target image.
And if the data volume of the target image is larger than or equal to a preset data volume threshold, acquiring parameters to be configured of the target image, wherein the parameters to be configured comprise a resolution parameter, a compression quality parameter and an image size parameter. The parameter to be configured is used for adapting the target image, so that the target image is more suitable for being displayed on the target equipment. It should be noted that the target device includes a terminal device or other display devices, and the other display devices include, but are not limited to, a television, an intelligent refrigerator, and the like. The resolution parameter, the compression quality parameter, and the image size parameter are used to adapt the target image, and may be set according to an actual situation, which is not specifically limited in the present application. For example, the resolution parameter is a resolution according to the display screen of the target device, and optionally, the resolution parameter is consistent with the resolution of the display screen of 800 × 600.
And S103, processing the target image according to the resolution parameter, the compression quality parameter and the image size parameter, and outputting the processed target image.
After the parameters to be configured of the target image are determined, the target image is processed according to the resolution parameter, the compression quality parameter and the image size parameter in the parameters to be configured, and the processed target image is output. The output of the processed target image may be display, storage and/or transmission of the processed target image. The target image is processed according to the parameters to be configured of the target image, so that the processed target image can be well adapted to display on terminal equipment or other equipment, and a better display effect is achieved.
Illustratively, the parameter to be configured is a parameter adapted to loading presentation of a screen, where the screen may be a screen of the terminal device itself, such as a mobile phone screen; the display device may also be a screen of another display device connected to the terminal device, for example, the terminal device sends the processed target image to a wearable device (e.g., smart glasses) for display.
In one embodiment, processing a target image and outputting the processed target image includes: according to the compression quality parameters, performing quality compression on the target image to obtain a first target image; and performing resolution compression on the first target image based on the resolution parameters to obtain a second target image, and outputting the second target image. The compression quality parameter may be a preset compression quality ratio, which may be set according to an actual situation, and optionally, the compression quality ratio is 60. It should be noted that, the target image is subjected to quality compression according to a preset compression quality ratio, and the obtained compression quality of the first target image is the compression quality ratio. For example, when the compression quality ratio is 60, the compression quality of the resulting first target image is 60. When the data volume of the target image is large, the redundant data of the target image can be removed by performing quality compression on the target image, and the operation burden of the terminal equipment is reduced.
Because the screen sizes of different display devices are different, the resolution required to compress the picture to the resolution corresponding to the specified screen size is different. The terminal device performs resolution compression on the first target image based on the preset resolution parameter to obtain a second target image with resolution corresponding to the resolution parameter, and meanwhile, the second target image can be sent to a second terminal device for display. It should be noted that the preset resolution parameter may be set according to an actual situation, which is not specifically limited in this application, and optionally, the resolution parameter may be a resolution of 800 × 600 corresponding to a screen size of the second terminal device.

The image size parameter may include only the width and height of the target image, and may also include the length, width and height of the target image. It should be noted that the preset correspondence table between the resolution parameter and the image size parameter may be set according to actual situations, which is not specifically limited in this application.

The user can determine whether to continue compressing the first target image based on a control button of a display page of the terminal device, and the terminal device performs corresponding processing according to the operation of the control button by the user. For example, if the user touches the "continue compression" button, the terminal device continues to compress the first target image, and obtains the first target image after continuing to compress. It is to be understood that, after the resolution compression is performed on the first target image, the obtained second target image may be previewed, and the present application is not limited in particular.
In the image processing method provided by the embodiment, the target image with a large loading data volume is determined, the resolution parameter, the compression quality parameter and the image size parameter of the target image are set by the outside of the user, or the resolution parameter, the compression quality parameter and the image size parameter of the target image are obtained by the default value set inside the terminal device, and the target image is processed according to the obtained resolution parameter, compression quality parameter and image size parameter, so that an image meeting the personalized requirements of the user or meeting the display standard of the target device is obtained, and the adaptability and the display effect of the target image on different display devices are effectively enhanced.
