Detailed ways

The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and/or" in the specification and claims represents at least one of the connected objects, and the character "/" generally indicates that the objects associated with each other are in an "or" relationship.

The following, in conjunction with the accompanying drawings, describes in detail the image processing method, device, electronic device and medium provided in the embodiments of the present application through specific embodiments and their application scenarios.

The image processing method provided in the embodiment of the present application is applied to the scenario of printing large-size images. The specific application scenario can be determined according to usage requirements and is not limited by the present application.

Exemplarily, take the scenario of printing Picture 1 (i.e., the first picture) as an example. In the related art, if the user wants to print Picture 1 on a paper of a specific size (such as A4 paper), and the size of Picture 1 is much larger than the size of the A4 paper. At this time, it is necessary to set the print size of Picture 1 to A4 size after entering the print preview interface corresponding to Picture 1, so as to reduce the size of Picture 1 to A4 size, and then print it. Because the above-mentioned scheme of reducing the size of Picture 1 for printing will make the content of the scaled Picture 1 unclear, resulting in lower quality of the printed picture.

In the embodiment of the present application, if the user wants to print an image on a paper of a specific size (such as A4 paper), The size of the picture 1 is much larger than the size of the A4 paper. At this time, the user can input the picture 1 to trigger the electronic device to display the preview operation interface corresponding to the picture 1, and display a dividing line in the preview operation interface according to the size of the A4 paper, and then divide the picture 1 into multiple sub-pictures (i.e., the second pre-printed pictures) matching the size of the A4 paper according to the dividing line, and finally print the multiple sub-pictures respectively. Therefore, the contents of the divided multiple sub-pictures can be clearly displayed, thereby improving the quality of the printed pictures.

The execution subject of the picture processing method provided in this embodiment may be a picture processing device, which may be an electronic device, or a control module or a processing module in the electronic device, etc. The technical solution provided in the embodiment of this application is described below using an electronic device as an example.

The present application provides a method for processing an image. As shown in FIG1 , the method for processing an image may include the following steps 201 to 204:

Step 201: The electronic device receives a first input of a first picture.

In the embodiment of the present application, the first picture mentioned above may be any picture stored in the electronic device.

In an embodiment of the present application, the image type of any of the above-mentioned images may include document images and non-document images.

Exemplarily, the above-mentioned document-type images may be images containing text, such as mind maps, promotional slogan images, article screenshots, etc.

Exemplarily, the non-document image may be an image that does not contain text, such as a landscape image, a selfie image, and the like.

In the embodiment of the present application, the first input is used to set the printing parameters corresponding to the first image.

In the embodiment of the present application, the above-mentioned first input can be a click input of the user on the above-mentioned first image, or other feasible input, which is not limited in the embodiment of the present application.

Step 202: In response to the first input, the electronic device displays a preview operation interface according to the target printing parameters corresponding to the first input when the image size of the first image is larger than a preset size.

In an embodiment of the present application, the first image and at least one dividing line are displayed in the preview operation interface.

Exemplarily, the preview operation interface is used to preview the printing effect of the first image and receive user input for adjusting the at least one dividing line.

Exemplarily, the at least one dividing line is used to divide the first image into a plurality of areas.

It should be noted that the above-mentioned multiple areas may include a core display area and an edge blank area.

In an embodiment of the present application, the electronic device can identify the core display area and the edge blank area of the above-mentioned first image through image recognition technology.

For example, as shown in FIG2 , the preview operation interface 10 displays core display areas (such as area A, area B, area C, and area D), edge blank areas (such as area E, area F, area G, and area H), and dividing lines 11, 12, 13, and 14.

In the embodiment of the present application, the preset size may be a default printing paper size of the electronic device, or may be a printing paper size manually set by the user.

In an embodiment of the present application, the electronic device may set different target printing parameters according to the type of the first picture.

In a possible example, when the first image is a document-type image, the target printing parameters include the desired printing paper size, the desired printing font size, and the desired printing direction. At this time, the electronic device can recognize the main text in the first image through optical character recognition technology (OCR). Then, the zoom ratio corresponding to the first image is calculated according to the desired printing font size and the desired printing paper size. In addition, when the text size in the first image is not uniform, the text with the largest number of the same font size is used as the basis for calculation.

In another possible example, when the first image is a non-document image, the target printing parameters include a desired printing paper size and a desired printing direction, etc. At this time, the electronic device calculates the zoom ratio corresponding to the first image according to the resolution information of the first image.

In an embodiment of the present application, the electronic device can determine whether the first image is a large image (i.e., whether the image size is larger than a preset size) based on the first image and the target printing parameters, and display a preview operation interface if the first image is a large image.

It should be noted that whether the same picture is a large picture is determined based on the size of the preset size. For example, if the size of the first picture is A4, if the preset size is greater than or equal to A4, then the first picture is not a large picture; if the preset size is less than A4, then the first picture is a large picture.

Step 203: The electronic device divides the first picture into N second pre-printed pictures according to the display position of at least one dividing line on the first picture.

In the embodiment of the present application, N is an integer greater than 1.

In the embodiment of the present application, the image sizes of the N second pre-printed images match the preset size.

Step 204: The electronic device prints N second pre-printed pictures respectively according to the target printing parameters.

In an embodiment of the present application, the electronic device can send the N second pre-printed images to a printing program according to target printing parameters, and print the N second pre-printed images.

In the picture processing method provided in the embodiment of the present application, after receiving a first input of a first picture, the electronic device can, in response to the first input, process the first picture when the picture size of the first picture is larger than a preset size. In the case of the above, according to the target printing parameters corresponding to the above first input, a preview operation interface is displayed, in which the above first picture and at least one dividing line are displayed; according to the display position of the at least one dividing line on the above first picture, the above first picture is divided into N second pre-printed pictures; according to the above target printing parameters, the above N second pre-printed pictures are printed respectively. In this way, by displaying at least one dividing line for dividing the first picture in the preview operation interface, the electronic device can divide the pictures into multiple pictures matching the printing paper size according to the at least one dividing line, so that the picture content of each divided picture can be clearly displayed, thereby improving the quality of the printed pictures.

Optionally, in the embodiment of the present application, in the above step 202, “the electronic device displays a preview operation interface according to the target printing parameter corresponding to the first input” may include the following step 202a:

Step 202a: the electronic device displays a preview operation interface according to the first dividing line template and based on target printing parameters.

In the embodiment of the present application, the preview operation interface displays the dividing lines in the first dividing line template.

In the embodiment of the present application, the first dividing line template may be automatically generated by the electronic device according to the target printing parameters.

It should be noted that the image size of each second pre-printed image divided by the dividing lines in the first dividing line template matches the expected printing size in the target printing parameters.

In this way, the electronic device can automatically generate a dividing line template according to the printing parameters corresponding to the first input, thereby improving the efficiency of the electronic device in dividing the first picture.

Optionally, in the embodiment of the present application, after the above step 202a, the image processing method provided in the embodiment of the present application may further include the following step 202b:

Step 202b: The electronic device receives a second input for moving the first picture displayed in the preview operation interface.

In an embodiment of the present application, the second input is used to move a display position of the at least one dividing line on the first picture.

In the embodiment of the present application, the second input may be a user's dragging input of the first image, or other feasible input, which is not limited in the embodiment of the present application.

Exemplarily, the dragging input may be a user pinching and dragging the first image, and at this time, the dividing line in the preview operation interface will change its display position in the first image as the first image moves.

In an embodiment of the present application, when the user moves the first picture, the dividing line in the preview operation interface can be hidden or displayed, and this application does not limit this.

Further, in combination with the above step 202b, the above step 203 of "the electronic device divides the first image into N second pre-printed images according to the display position of at least one dividing line on the first image" may include the following step 203a:

Step 203a: In response to the second input, the electronic device divides the first picture into N second pre-printed pictures according to the display position of at least one dividing line on the moved first picture.

In an embodiment of the present application, since the display position of the at least one dividing line is not movable, the electronic device can receive input for moving the first image to achieve the effect of indirectly moving the at least one dividing line. The electronic device can then divide the first image into multiple pre-printed images according to the dividing effect of the moved dividing line on the first image.

In this way, after displaying the first dividing line template, the electronic device can also adjust the display position of the dividing line on the first picture by receiving user input to change the dividing position, thereby increasing the flexibility of the electronic device in dividing the first picture.

Optionally, in the embodiment of the present application, after the above step 202a, the image processing method provided in the embodiment of the present application may further include the following steps 202c and 202d:

Step 202c: The electronic device receives a third input to the preview operation interface.

In the embodiment of the present application, the third input is used to update the dividing line displayed on the preview operation interface.

In the embodiment of the present application, the third input may be a click input by the user on the preview operation interface, or other feasible input, which is not limited in the embodiment of the present application.

In the embodiment of the present application, a dividing line template switching control is also displayed in the above-mentioned preview operation interface.

Exemplarily, the above-mentioned dividing line template switching control is used to trigger the electronic device to display different dividing line templates.

Step 202d: the electronic device responds to the third input and updates the preview operation interface according to the second dividing line template corresponding to the third input.

In the embodiment of the present application, the updated preview operation interface displays the dividing line in the second dividing line template.

Exemplarily, the second dividing line template may be a dividing line template preset in the electronic device.

For example, in combination with Figure 2, a switch control 15 is also displayed in the preview operation interface 10. After the user clicks the switch control 15 (that is, the above-mentioned dividing line template switch control), as shown in Figure 3, dividing lines 21, 22, 23, and 24 are displayed in the preview operation interface 10.

In the embodiment of the present application, the updating preview operation interface may be to switch the first dividing line template in the preview operation interface to the second dividing line template. After the template is applied, the user can still adjust the display position of the dividing line corresponding to the second dividing line template on the first picture.

In this way, by presetting different dividing line templates in the electronic device, after receiving a switching input from the user, the different dividing line templates are switched, so that the electronic device has more options for dividing the first picture.

Optionally, in the embodiment of the present application, after the above step 202, the image processing method provided in the embodiment of the present application may further include the following steps 205 and 206:

Step 205: The electronic device receives a fourth input to the preview operation interface.

In an embodiment of the present application, the fourth input is used to trigger the electronic device to save the preview segmentation result image corresponding to the first image.

It should be noted that the preview segmentation result image is used to indicate the current segmentation effect of the segmentation line displayed on the first image in the preview operation interface (such as the relative display position of the segmentation line and the first image, the number of segmentation lines, etc.).

In the embodiment of the present application, the fourth input may be a click input by the user on the preview operation interface, or other feasible input, which is not limited in the embodiment of the present application.

Step 206: In response to the fourth input, the electronic device saves the preview segmentation result image corresponding to the first image in the preview operation interface.

In an embodiment of the present application, after the electronic device displays at least one dividing line in the preview operation interface, the preview segmentation result image of the first image by the at least one dividing line can be saved in the electronic device, so that when the electronic device subsequently reprints the first image, the segmentation effect of the preview segmentation result image can be directly used for printing.

In this way, by saving the preview segmentation result image corresponding to the image, when the image is reprinted, the segmentation effect of the preview segmentation result image is directly used for printing, thereby improving the efficiency of printing images by the electronic device.

Optionally, in the embodiment of the present application, the target printing parameters include a first printing format, and the step 204 of “the electronic device prints N second pre-printed images respectively according to the target printing parameters” may include the following step 204a:

Step 204a: The electronic device prints N second pre-printed pictures respectively based on the first printing format.

In the embodiment of the present application, the first printing format is: the first side edge of the second pre-printed image is printed in a manner close to the edge of the paper. In other words, the first printing format is an edge-to-edge printing format.

It should be noted that the first side edge is a side edge divided by a dividing line in the second pre-printed image.

In an embodiment of the present application, when the electronic device prints the above-mentioned N second pre-printed pictures, the side edge divided by the dividing line in each second pre-printed picture can be aligned with the corresponding side edge of the printing paper, so that there is no inner margin between the printed second picture and the edge of the paper; and each of the above-mentioned second pre-printed pictures is printed according to the above-mentioned target printing parameters, so that each frame of the printed second picture is consistent with the second pre-printed picture in the preview operation interface.

In this way, by printing the second pre-printed image adjacent to the edge, the second image printed subsequently can be easily spliced.

Optionally, in the embodiment of the present application, after the above step 201, the image processing method provided in the embodiment of the present application may further include the following step 301:

Step 301: the electronic device prints a preview segmentation result image of the first image in the preview operation interface in response to a first input and according to target printing parameters.

In an embodiment of the present application, after dividing the first image into multiple second pre-printed images, the electronic device can also print out the preview segmentation result image of the first image in the preview operation interface according to the target printing parameters and use it as the cover.

Optionally, in the embodiment of the present application, in combination with the above step 301, after the above step 201, the image processing method provided in the embodiment of the present application may further include the following steps 302 and 303:

Step 302: In response to the first input, the electronic device increases a number at a preset position of each second pre-printed image in the preview segmentation result image based on the display positions of the N second pre-printed images in the preview segmentation result image to generate a directory image.

In the embodiment of the present application, the preset position may be any position in the second pre-printed image.

In an embodiment of the present application, the electronic device may number the second pre-printed images according to the display position order of the second pre-printed images in the preview segmentation result image to generate a directory image.

Exemplarily, the display position sequence may be the sequence of the N second pre-printed images in the preview segmentation result image from left to right and from top to bottom.

It should be noted that the above catalog image is used to indicate the sequence of the above N second pre-printed images.

Step 303: The electronic device prints the catalog image according to the target printing parameters.

In an embodiment of the present application, the electronic device can also number the above-mentioned N second pre-printed pictures in the preview operation interface to generate a directory picture, and print out the directory picture according to the target printing parameters, so that after printing out the N second pictures, the above-mentioned N second pictures can be used as sub-picture sets according to the respective numbers in the directory picture for easy sorting and classification.

In addition, after printing out the N second pre-printed pictures after the above numbering, the electronic device can directly splice the N second pictures according to the number of each second picture to restore the above first picture, making the splicing more efficient.

For example, in combination with FIG. 2 , as shown in FIG. 4 , the preview operation interface 10 also displays the corresponding numbers (such as number (1), number (2), number (3), number (4)) in area A, area B, area C, and area D. Then, the user clicks the print control 16 to print out the preview segmentation result image (the image composed of area A, area B, area C, and area D as a whole) displayed in the preview operation interface 10 as the cover; the second pre-printed images corresponding to area A, area B, area C, and area D are also printed out as the sub-images in the sub-image set. Among them, the above-mentioned cover is shown in FIG. 5 , the sub-image corresponding to the above-mentioned area A is shown in FIG. 6 , the sub-image corresponding to the above-mentioned area B is shown in FIG. 7 , the sub-image corresponding to the above-mentioned area C is shown in FIG. 8 , and the sub-image corresponding to the above-mentioned area D is shown in FIG. 9 .

It should be noted that the above-mentioned area A, area B, area C, and area D are the above-mentioned second pre-printed pictures, and the above-mentioned sub-pictures are all printed according to the edge-to-edge printing format.

In this way, when users need to print large images, they can quickly split the large images to achieve the best printing effect. In addition, the large images will not be over-compressed, making the printed images clearer and easier to view, and the paper utilization rate is also higher.
