It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

If a user needs to upload an image with a large difference in pixel aspect ratio (for example, an image with a pixel aspect ratio of 1:200 or a pixel aspect ratio of 200: 1) from a terminal device, the existing solutions usually ensure that the pixel aspect ratio and the file size of the image can be processed by the terminal device by limiting the maximum pixel width and the pixel height of the image (for example, limiting the maximum pixel width to 4000x4000), scaling the original image so that the image is limited to the maximum pixel width, cropping the content of the original image, and highly compressing the original image, however, the processing is bad, which may result in loss of information of the image and may not ensure the definition of the image, and in addition, when the terminal device is used to preview the image, the image can only be previewed as a whole.

To solve the above problems in the prior art, the present invention provides an image processing method, as shown in fig. 1, which is a flowchart of an image processing method provided in an embodiment of the present invention, and includes the steps of:

Step 101, determining a target pixel aspect ratio of a target image.

and 102, carrying out image cutting on the target image according to the width-height ratio of the target pixel to obtain at least two cut images.

and 103, respectively compressing the at least two cut images, and uploading the compressed cut images to a server for storage.

By the aid of the processing flow, segmentation and compression processing of the image with the super-long proportion are achieved, and definition of the image with the super-long proportion is guaranteed.

As shown in fig. 2, a flowchart is a specific implementation flow of the image processing method according to the embodiment of the present invention, and the image processing method specifically includes the following steps:

Step 201, acquiring the pixel width and height of the target image.

In this step, for a target image selected by a user, if a terminal device desires to acquire the pixel width and height of the target image, the target image may be directly acquired through image information carried in the target image, or may be obtained by directly analyzing the target image, which is certainly not limited to this, and any processing mode capable of acquiring the pixel width and height of the target image is within the protection scope of the present invention.

In step 202, a target pixel aspect ratio is calculated based on the pixel aspect ratio.

In an example, if the pixel width and height of the target image selected by the user is 2000 × 100, the target pixel width-height ratio is 20:1 as calculated by the pixel width and height.

step 203, comparing the target pixel aspect ratio with a preset pixel aspect ratio.

If the target pixel aspect ratio is greater than the predetermined pixel aspect ratio, go to step 204, otherwise go to step 206.

And 204, performing image cutting on the target image to obtain at least two cut images.

In this step, when the target image is cut, image cutting is performed on the target image according to a preset pixel width-to-height ratio, and cutting is stopped until the pixel width-to-height ratio of the remaining portion of the target image is not greater than the preset pixel width-to-height ratio, so as to obtain at least two cut images with the preset pixel width-to-height ratio, or at least one cut image with the preset pixel width-to-height ratio, and one cut image smaller than the preset pixel width-to-height ratio.

further, image segmentation is performed on the target image according to a preset pixel width-to-height ratio, which specifically includes any one of the following modes:

(1) and cutting the pixel height value of the target image according to a preset pixel width-height ratio by taking the pixel width value of the target image as a reference.

(2) And cutting the pixel width value of the target image according to a preset pixel width-height ratio by taking the pixel height value of the target image as a reference.

of course, the selection of the processing mode completely depends on the pixel width and the pixel height of the target image, and if the pixel width value is smaller than the pixel height value, the processing mode is selected to be (1); if the pixel width value is larger than the pixel height value, selecting (2) to process; in a special scenario, if the pixel width value is equal to the pixel height value, both (1) and (2) above can be applied.

as in the foregoing example, if the pixel width of the target image is 2000 × 100, the cutting process is performed according to (2) above, and if the preset pixel width-to-height ratio during cutting is 4:3, 26 cut images with a pixel width of 75 × 100 and 1 cut image with a pixel width of 50 × 100 can be obtained after image cutting.

In this step, still include:

as in the foregoing example, for 27 cut images obtained by image cutting, each cut image is marked in turn in the order of cutting, so that the front-rear positional relationship between the cut images can be distinguished based on the marks.

Note that, in the marking, the marking may be performed by using numbers (for example, the first cut image mark 1, the second cut image mark 2 … …, and the 27 th image mark 27), but the marking method is not limited to this, and any other marking method may be used as long as the selected arbitrary marking method can be used to indicate the front-back positional relationship between the cut images.

step 205, the at least two cut images are compressed respectively.

In this step, the compressing the at least two cut images respectively includes:

As in the previous example, the selected preset maximum pixel width is 80x80, and after the 26 cut images with 75x100 pixel width and 1 cut image with 50x100 pixel width are compressed according to the maximum pixel width, 26 cut images with 60x80 pixel width and 1 cut image with 40x80 pixel width are obtained.

Step 206, compressing the target image.

and directly compressing the target image according to the preset maximum pixel width and height to obtain the target image meeting the preset maximum pixel width and height.

and step 207, uploading the compressed image to a server for storage.

after the processed image is uploaded to the server, the embodiment of the present invention further includes a display portion of the processed image on the terminal device, which specifically includes:

further, the image list information further includes mark information of each cut image, and the extracting and displaying of the cut image corresponding to the placeholder map according to the selected placeholder map includes:

As in the foregoing example, after acquiring the image list information of the target image, the terminal device sets the placeholder maps of the cut images according to the pixel width and height values of 27 cut images in the target image; after the occupation map desired to be displayed by the user is 11 (corresponding to the 11 th cut image), the occupation map is determined to correspond to the 11 th cut image according to the occupation map, the 11 th cut image is extracted from the server according to the mark information 11 of the 11 th cut image, and the 11 th cut image is displayed after the extraction.
