[0026] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0027] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The main solution of the embodiment of the present application is: obtaining image size information of an image to be displayed, and obtaining target size information of each of multiple target displays; determining display sub-images corresponding to each of the multiple target displays from the image to be displayed based on the image size information and each of the target size information, wherein the position of the display sub-image in the image to be displayed is consistent with the position of the corresponding target display screen in the display group, the proportion of the display sub-image in the image to be displayed is consistent with the proportion of the corresponding target display screen in the display group, and the size of the display sub-image is consistent with the size of the corresponding target display screen, the target display screen is the display screen of the target display, and the display group is obtained by combining the multiple target displays; sending each of the display sub-images to the corresponding target displays, so that the multiple target displays display their respective display sub-images.

[0029] In this embodiment, for ease of description, the following description is made with the image display device as the execution subject. When an image is displayed on multiple target displays in a linked screen, the image is usually displayed as multiple images. However, due to manufacturing and design limitations, there is usually a border around the edge of the display that cannot display the image, so that when multiple target displays are linked to display the image, the border forms an obvious dividing line in the image, causing the image to be interrupted at the border position, destroying the continuity and integrity of the image, and affecting the effect of multiple displays displaying the image in a linked screen.

[0030] In the embodiment of the present application, the display sub-image is actually an image in the image to be displayed that has the same position and size as the visible area of ​​the target display. Some image resources in the image to be displayed other than the display sub-image correspond to the border parts of each target display. When multiple target displays are combined to display the same image, the visible area of ​​each target display only displays the display sub-image that has the same size and position as its own display screen.

[0031] Compared with the existing method of jointly displaying the entire target image through the display screen areas of each display, the embodiment of the present application can present the effect that part of the image area is obscured by the physical frame of the display during the natural extension of the image, avoiding the effect of the physical frame of the display interrupting the image to be displayed when multiple displays are displayed on a connected screen, so that the image finally displayed by the multiple target displays is consistent in visual perception, thereby improving the consistency and immersion of the images displayed on the multiple displays on a connected screen, improving the effect of displaying images on the multiple displays on a connected screen, and optimizing the user visual experience.

[0032] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an image display device, etc. The following takes an image display device as an example to illustrate this embodiment and the following embodiments.

[0033] Based on this, the present application embodiment provides an image display method, referring to Figure 1 This is a flow chart of the first embodiment of the image display method of the present application.

[0034] In this embodiment, the image display method includes steps S10 to S30.

[0035] Step S10, obtaining image size information of an image to be displayed, and obtaining target size information of each of a plurality of target displays.

[0036] It should be noted that the image to be displayed is an image that needs to be displayed on multiple monitors. The image size information can be image pixels or resolution, which is not limited here. The image size information includes information representing the horizontal size of the image and information representing the vertical size of the image. The method of obtaining the image size information is not limited here. It can be data input by receiving engineers; it can also be obtained by parsing the file description information of the image to be displayed, where the file description information can include basic information of the image to be displayed, such as pixels, resolution, image size, etc.

[0037] The target display is a plurality of displays that are linked to display the image to be displayed. The size of each target display can be the same or different, and there is no limitation here. The target size information is information that characterizes the size of the target display. It should be noted that the target display includes a visible area (that is, a display screen) and a frame for displaying the image. The target size information includes at least the size of the display screen and the size of the display frame. The specific form is not limited here and can be set according to actual needs. The specific method of obtaining the target size information is not limited here. It can be received by receiving data input by engineers, or it can be obtained by parsing the device movement information of each target display. The device movement information can include basic properties of the display, such as resolution, diagonal length of the display screen, etc.

[0038] Exemplarily, in one embodiment, the target size information can be obtained by parsing the device movement information of the target display. In this embodiment, the image display device receives the device movement information sent by each display and saves it in a preset database. When determining the target size information, the device movement information corresponding to the target display is extracted from the preset database and parsed to obtain the target size information. Specifically, before obtaining the target size information of each of the multiple target displays, step S40 is also included: receiving the device movement information sent by different displays, and saving each device movement information to the preset database after verification.

[0039] First, the device movement information sent from different displays is received. After receiving this information, each device movement information is verified to confirm its validity and authenticity. Once it passes the verification, the information will be saved in the preset database. Through strict verification and centralized management, the obtained device movement information is ensured to be accurate, which enhances the stability and security of the entire display system.

[0040] In this embodiment, the process of obtaining target size information of each of the multiple target displays may include step S101: reading device movement information corresponding to each of the multiple target displays from a preset database, and parsing the device movement information corresponding to each of the multiple target displays to obtain the target size information of each of the multiple target displays.

[0041] When the target size information needs to be obtained, the saved device movement information will be read from the preset database, and then the device movement information will be parsed to extract the specific size data of each display for subsequent image display configuration. It should be noted that by directly parsing the size data of the target display from the saved device information, the accuracy and adaptability of the image display are ensured, the tediousness of manually entering or searching for size information is reduced, and the possibility of human error is reduced.

[0042] Step S20, based on the image size information and each target size information, the display sub-images corresponding to each of the multiple target displays are determined from the image to be displayed, wherein the position of the display sub-image in the image to be displayed is consistent with the position of the corresponding target display screen in the display group, the proportion of the display sub-image in the image to be displayed is consistent with the proportion of the corresponding target display screen in the display group, and the size of the display sub-image is consistent with the size of the corresponding target display screen, the target display screen is the display screen of the target display, and the display group is a combination of multiple target displays.

[0043] It should be noted that the display screen of the target display is referred to as a target display screen. The combination of multiple target displays is referred to as a display group. The arrangement and combination of each target display in the display group is not limited here and can be set according to actual needs.

[0044] The images determined from the image to be displayed for each target display are referred to as display sub-images below, wherein for any display sub-image, the position of the display sub-image in the image to be displayed is consistent with the position of the target display screen corresponding to the display sub-image in the display group, the proportion of the display sub-image in the image to be displayed is consistent with the proportion of the target display screen corresponding to the display sub-image in the display group, and the size of the display sub-image is consistent with the size of the target display screen corresponding to the display sub-image. The proportion of the display sub-image in the image to be displayed represents the size of the display sub-image in the image to be displayed, specifically the ratio of the width of the display sub-image to the width of the image to be displayed and the ratio of the height of the display sub-image to the height of the image to be displayed. For example, if the image to be displayed is an image of 1920x1080 pixels and the display sub-image is 960x540 pixels, then the sub-image ratio is 1:2, which means that the size of the display sub-image is half of the image to be displayed. The ratio of the target display corresponding to the displayed sub-image in the display group is also called the device ratio, which is used to characterize the relative size of the target display in the display group and reflects the size relationship between the target display and the display group. For example, if the display group is a square array composed of four target displays of the same size, and one of the target displays occupies one quarter of the area of ​​the display group, then the ratio of the target display in the display group is 1:4.

[0045] In this embodiment, the process of determining the display sub-image is not limited here, and can be specifically determined according to the relative size between the size of the image to be displayed and the size of the display group.

[0046] When the size of the image to be displayed is consistent with the size of the display group, in one feasible implementation, the process of determining the display sub-image may be: first determine the display ratio between the image to be displayed and the display group, then process the display screen size contained in each target size information according to the display ratio, obtain the size information of the image resources displayed by the target display screens of the multiple target displays, and then determine the display sub-images of each target display screen from the image to be displayed based on the size information of the image resources displayed by each target display screen. The display ratio may specifically be the ratio of the image to be displayed relative to the display group, or the ratio of the display group relative to the image to be displayed, which is not limited here. In another feasible implementation, the process of determining the display sub-image may also be: respectively determine the device ratio of each target display screen in the display group, and then determine the display sub-image corresponding to the target display screen from the image to be displayed according to the device ratio. It should be noted that the device ratio may be the area ratio of the target display screen in the display group, or the length ratio of the length of the target display screen in the length of the display group. The length ratio may include the length ratio in the horizontal direction and / or the length ratio in the vertical direction, which is not shown here.

[0047] When the size of the image to be displayed is inconsistent with the size of the display group, in one feasible implementation, the process of determining the display sub-image may be: scaling the image to be displayed to obtain a scaled image according to the display ratio between the image to be displayed and the display group, and then determining the display sub-image from the scaled image. The specific process may refer to the case where the size of the image to be displayed is consistent with the size of the display group, which will not be elaborated here. In another feasible implementation, the process of determining the display sub-image may also be: first determining the image corresponding to the target display screen (hereinafter referred to as the split image) from the image to be displayed according to the device ratio, and then scaling the split image according to the size of the display screen of the target display. The specific process may be set according to actual needs and is not limited here.

[0048] Step S30 , sending each display sub-image to its corresponding target display, so that the multiple target displays can display their respective display sub-images.

[0049] Each display sub-image is sent to its corresponding target display through a preset transmission method, and multiple target displays proceed after receiving their respective display sub-images.

[0050] It should be noted that the preset transmission method is not limited here, and it can be through Bluetooth transmission, network transmission, etc. For example, in one embodiment, the target display can be equipped with an image display client, and the image display device can be equipped with a corresponding server. After obtaining the display sub-image, the image display device sends each display sub-image to the corresponding target display client through network transmission based on the server, and the client sends the display sub-image to the display unit of the target display for display.

[0051] In this embodiment, the position of the display sub-image in the image to be displayed is consistent with the position of the target display screen in the display group, the display ratio of the display sub-image relative to the image to be displayed is consistent with the display ratio of the target display screen relative to the display group, and the size of the display sub-image is consistent with the size of the target display screen. That is to say, the display sub-image is actually an image in the image to be displayed that has the same position and size as the visible area of ​​the target display screen, and some image resources in the image to be displayed other than the display sub-image correspond to the border parts of each target display. When multiple target displays are combined to display the same image, the visible area of ​​each target display only displays the display sub-image with the same size and position as its own display screen.

[0052] Compared with the existing method of jointly displaying the entire target image through the display screen areas of each display, the present embodiment can present the effect that part of the image area is obscured by the physical frame of the display during the natural extension of the image, thereby avoiding the effect that the physical frame of the display interrupts the image to be displayed when multiple displays are displayed on a connected screen, so that the image finally displayed by the multiple target displays is consistent in visual perception, thereby improving the consistency and immersion of the images displayed on the multiple displays on a connected screen, improving the effect of displaying images on the multiple displays on a connected screen, and optimizing the user visual experience.

[0053] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , the target size information includes the display screen size and the frame size, step S20: based on the image size information and each target size information, determining the display sub-images corresponding to each of the multiple target displays from the image to be displayed, including steps S201 to S205.

[0054] Step S201: determining the combined size information of the display group based on each target size information.

[0055] In this embodiment, the process of determining the display sub-image is as follows: first determine the display ratio between the image to be displayed and the display group; then process the display screen size contained in each target size information according to the display ratio to obtain the resource size information of the target display screen of each of the multiple target displays (that is, the size information of the image resource displayed by the target display screen); then determine the display sub-image of each target display screen from the image to be displayed based on each resource size information.

[0056] Specifically, in this embodiment, the size information of the display group is first obtained, which is hereinafter referred to as the combined size information for distinction. The combined size information is used to characterize the size of the display group. The combined size information can be obtained by receiving data input by an engineer, or it can be calculated based on the target size information of the target display and the arrangement of multiple target displays. The specific calculation process will not be repeated here.

[0057] In a specific implementation, when the combined size information is determined based on the individual target size information, the process of determining the combined size information may be:

[0058] a1, determine each outer contour display located at the edge of the display group among the multiple target displays.

[0059] In this embodiment, the edge of the display group refers to the outermost physical position in the display group, and the outer contour display is the display at the outermost physical position in the display group. For example, if the displays form a rectangular arrangement, the edge displays are those located at the four sides of the rectangle. Based on the display combination method, each target display located at the edge of the display group from multiple target displays is selected, and the specific process is not limited here.

[0060] a2. Calculate a first contour length of the display group in the horizontal direction and a second contour length of the display group in the vertical direction based on each outer contour size information, wherein the outer contour size information is target size information of the outer contour display.

[0061] It should be noted that the target size information of the outer contour display is called the outer contour size information, the total length of the display group in the horizontal direction (that is, the width direction) is called the first contour length, and the total length of the display group in the vertical direction (that is, the height direction) is called the second contour length. Figure 3 The schematic diagram of the display group shown, Figure 3 The d1 shown in is the first contour length, and the first contour length does not include the outer frame width of the outermost display in the horizontal outer contour display. Figure 3The d2 shown in is the second contour length, which does not include the outer frame width of the outermost display in the vertical outer contour display. Compared with incorporating the outer frame width of the outermost display into the contour length, this embodiment can make the starting and ending positions of the image to be displayed in the display group, thereby improving the display effect of the image to be displayed.

[0062] The method of calculating the first contour length and the second contour length is not limited here and can be set according to the combination of the display group. For example, when the display group is a combination of target displays of the same size, the first contour length can be obtained by multiplying the number of outer contour displays in the horizontal direction by the outer contour size information, and the second contour length can be obtained by multiplying the number of outer contour displays in the vertical direction by the outer contour size information; when the display group is a combination of target displays of different sizes, the first contour length can be obtained by accumulating the outer contour size information of the outer contour displays in the horizontal direction, and the second contour length can be obtained by accumulating the outer contour size information of the outer contour displays in the vertical direction.

[0063] In this embodiment, the outer contour size information includes the first display screen size and the outer contour frame size of the outer contour display; the first display screen size includes the first display screen width of the display screen of the outer contour display and the first display screen height of the display screen of the outer contour display; the outer contour frame size includes the distance between the edge of the display screen of the outer contour display and the display housing in the horizontal direction, that is, the first frame width, and the distance between the edge of the display screen of the frame of the outer contour display and the display housing in the vertical direction, that is, the second frame width. When the display group is obtained by combining target displays of the same size, the process of calculating the first contour length of the display group in the horizontal direction and the second contour length of the display group in the vertical direction based on each outer contour size information may include:

[0064] a21, determine a first number and a second number, wherein the first number is the number of outer contour displays in the horizontal direction of the display group, and the second number is the number of outer contour displays in the vertical direction of the display group.

[0065] In this implementation, the number of outer contour displays of the display group in the horizontal direction and the vertical direction is determined. For displays of the same size, the number of rows and columns directly determines the horizontal range and the vertical range of the display group.

[0066] a22, based on the first border width and the first number, the first interval length between each outer contour display in the horizontal direction is calculated, based on the first display screen width and the first number, the first visible total length of each outer contour display in the horizontal direction is calculated, and the first interval length and the first visible total length are superimposed to obtain the first contour length.

[0067] The process of calculating the first interval length between each outer contour display in the horizontal direction based on the first border width and the first number may be: calculating the adjacent interval width between two adjacent outer contour displays based on the first border width, subtracting one from the first number to obtain the interval number, and multiplying the interval number by the adjacent interval width to obtain the first interval length. The specific calculation formula for the first interval length may be:

[0068] BS=(N1-1)*(A+B)

[0069] Wherein, BS is the first interval length, N1 is the first number, A+B is the adjacent interval width between two adjacent outer contour displays, A and B are respectively the first border widths of the two adjacent outer contour displays, and it should be noted that the left border width and the right border width of the outer contour display may be different or the same, so A and B may be different or the same. When the left border width and the right border width of the outer contour display are different, the first border width includes the left border width and the right border width.

[0070] The process of calculating the first visible total length of each outer contour display in the horizontal direction based on the first display screen width and the first number may be: obtaining the first visible total length by multiplying the first number by the first display screen width.

[0071] The first interval length and the first visible total length are superimposed to obtain a first contour length. The specific calculation formula for the first contour length may be:

[0072] CW=N1*X1+BS

[0073] Wherein, CW is the first contour length, N1 is the first number, X1 is the first display screen width, and BS is the first interval length.

[0074] a23, based on the second border width and the second number, the second spacing length between each outer contour display in the vertical direction is calculated, based on the display screen height and the second number, the second visible total length of each outer contour display in the vertical direction is calculated, and the second contour length is obtained by superimposing the second spacing length and the second visible total length.

[0075] The specific calculation process is not described here, please refer to a12.

[0076] Specifically, the calculation formula for the specific second interval length may be:

[0077] BH=(N2-1)*(C+D)

[0078] Among them, BH is the second interval length, N2 is the second number, C+D is the adjacent interval width between two adjacent outer contour displays, C and D are respectively the first border widths of two adjacent outer contour displays, and C and D may be different or the same.

[0079] The specific calculation formula of the second contour length can be:

[0080] CH=N2*X2+BH

[0081] Wherein, CH is the second contour length, N2 is the second number, X2 is the display screen height, and BH is the second interval length.

[0082] It should be noted that the first number and the second number may be the same or different, and there is no limitation here, depending on the target combination mode of the display group.

[0083] a3, taking the first contour length and the second contour length as combined size information.

[0084] Step S202: determining a display ratio between the image to be displayed and the display group based on the image size information and the combination size information.

[0085] It should be noted that the display ratio can specifically be the ratio of the image to be displayed relative to the display group, or the ratio of the display group to the image to be displayed. There is no limitation here. The display ratio can specifically include the ratio between the horizontal size of the image to be displayed and the horizontal size of the display group, and the ratio between the vertical size of the image to be displayed and the vertical size of the display group.

[0086] Step S203 : for any display to be processed among the multiple target displays, determining resource size information corresponding to the display to be processed based on the display ratio and the size information to be processed, wherein the size information to be processed is the target size information of the display to be processed.

[0087] It should be noted that any one of the multiple target displays is referred to as a display to be processed, and the target size information of the display to be processed is referred to as size information to be processed.

[0088] In this embodiment, resource size information corresponding to the display to be processed is determined based on the display ratio and the size information to be processed. The resource size information represents the size of the image resource displayed on the display to be processed. The resource size information may be the same as the display screen size of the display to be processed, or may be different from the display screen size of the display to be processed. When the resource size information is different from the display screen size of the display to be processed, the image determined from the image to be displayed based on the resource size information can be scaled to obtain a display sub-image.

[0089] In a specific implementation, the display ratio between the image to be displayed and the display group includes a horizontal display ratio and a vertical display ratio, the size information to be processed includes a second display screen size of the display to be processed, and the second display screen size includes a second display screen width of the display to be processed and a second display screen height of the display to be processed. The process of determining the resource size information corresponding to the display to be processed based on the display ratio and the size information to be processed may be:

[0090] b1, the image width is obtained by multiplying the second display screen width by the horizontal display ratio, and the image height is obtained by multiplying the second display screen height by the vertical display ratio.

[0091] b2, taking the image width and image height as the resource size information corresponding to the display to be processed.

[0092] Step S204, obtaining a display combination mode of multiple target displays, and determining display screen position information of a display screen to be processed in the display group based on the display combination mode and each target size information, wherein the display screen to be processed is the display screen of the display to be processed.

[0093] It should be noted that the arrangement and combination method of combining multiple target displays into a display group is called a display combination method, the display screen of the display to be processed is called a display screen to be processed, and the information representing the relative position of the display screen to be processed in the display group is called display screen position information.

[0094] The display screen position information is determined based on the display combination mode and each target size information, so as to subsequently determine which part of the image to be displayed corresponds to which target display.

[0095] In a specific implementation, the process of determining the display screen position information of the display screen to be processed in the display group based on the display combination mode and each target size information may be:

[0096] c1, determining the arrangement positions of the multiple target displays based on the display combination method.

[0097] c2. Based on the target size information of the positioning display and the size information to be processed, determine the corner point position information of the upper left corner of the display screen to be processed, and use the corner point position information as the display screen position information, wherein the positioning display is: a target display among multiple target displays whose horizontal arrangement position is to the left of the display to be processed and whose vertical arrangement position is above the display to be processed.

[0098] It should be noted that the method for determining the corner point position information is not limited here. In one feasible implementation, the corner point coordinates of the upper left corner of the display screen to be processed in the preset coordinate system can be calculated based on the target size information of the positioning display and the target size information of the display screen to be processed, and the corner point coordinates are used as the corner point position information, wherein the preset coordinate system uses the upper left corner of the display screen of the starting display as the coordinate origin, and uses the straight line where the edge of the display screen of the starting display with the upper left corner as the endpoint as the coordinate axis; in another feasible implementation, the upper left corner of the starting display can be used as the starting point, and based on the target size information of the positioning display and the target size information of the display screen to be processed, the horizontal distance and vertical distance of the upper left corner of the display screen to be processed relative to the starting point are calculated, and the horizontal distance and vertical distance are used as the corner point position information.

[0099] Step S205 , determining a display sub-image of the display to be processed in the image to be displayed according to the display screen position information and the resource size information.

[0100] According to the display screen position information and the resource size information, an image segment suitable for the display to be processed is cut out from the image to be displayed, that is, a display sub-image of the display to be processed.

[0101] The process of determining the display sub-image of the display to be processed in the image to be displayed according to the display screen position information and the resource size information can be: determining the starting coordinates of the display to be processed in the image to be displayed corresponding to the display to be processed according to the display screen position information, and calculating the specific area to be cropped in the image to be displayed in combination with the resource size information, specifically including the cropping width and the cropping height, so as to obtain the cropping range based on the starting coordinates; and cropping the display sub-image from the image to be displayed according to the cropping range.

[0102] In this embodiment, by determining the combined size information of the display group based on each target size information, determining the display ratio between the image to be displayed and the display group based on the image size information and the combined size information, and then determining the resource size information corresponding to the display to be processed based on the display ratio and the size information to be processed, it can be ensured that there is a comprehensive planning of the size of the entire display system, and that image resources are reasonably allocated subsequently, ensuring that each display can obtain an image portion of a suitable size, so that the image to be displayed can adapt to display groups of different sizes and configurations, thereby enhancing the flexibility of displaying the image to be displayed on multiple displays.

[0103] By obtaining the display combination method of multiple target displays and determining the display position information of the display to be processed in the display group based on the display combination method and each target size information, it is possible to ensure that the image content displayed by each display matches its physical position in the display group, avoiding content dislocation, helping to optimize the overall layout of the display combination, and improving the consistency and coherence of visual effects.

[0104] Finally, the display sub-image of the display to be processed is determined in the image to be displayed according to the display position information and resource size information, ensuring that the image content displayed on each display is accurately matched, improving the accuracy and quality of image display, and enhancing the user experience.

[0105] For example, in order to help understand the technical concept or technical principle of image display after the present embodiment is combined with the above-mentioned embodiment 1 and embodiment 2, a specific process of image display is proposed. In this embodiment, the image display device is equipped with a server, and the target display is equipped with a client. The server is used to receive device-related information from the client, perform image processing on the image to be displayed, etc. Specifically, refer to Figure 4 As shown in the timing diagram, the interaction process between the server of the image display device and the client of the target display may be:

[0106] 1. After logging in, the super administrator enters the device movement information on the client of the target display. The device movement information entry page can refer to Figure 5 , Figure 5 The following table shows some parameters of the device movement information: Client Type, Diagonal Size, Resolution, Model, PID (Product identity), Brightness, Bezel Width, Dimensions. Figure 5 The parameters shown are examples of device movement information. Then the super administrator clicks Save, and the client sends the device movement information to the server in response to the Save operation.

[0107] 2. After receiving the device movement information, the server will perform data verification and put it into storage if the verification passes. Then, the server will return the status information to the client.

[0108] 3. When multi-monitor joint-screen display is required, the client publishes the joint-screen task and asynchronously publishes the resource cropping task to the server.

[0109] 4. After receiving the task, the server performs resource calculation and cuts the image to be displayed according to the result of resource calculation. It should be noted that before cutting resources, the super administrator logs in to the server and selects resource joint screen settings in the Content module of the server, and in the Schedule module, CreateVideoWall to push the joint screen data.

[0110] 5. The server asynchronously returns the cutting information to the client, completing the entire interaction process.

[0111] Specifically, the process of Lianping Cloud frame cutting can be referred to Figure 6 In this embodiment, a single display height, display width (ie, the display screen size in the target size information) and a total distance between adjacent borders (ie, the adjacent interval width) are obtained.

[0112] In a specific implementation, a single display height and display width can be calculated according to the diagonal length and the screen ratio by the Pythagorean theorem to obtain a single display height and display width (i.e., display screen size). Assuming that the display width is x, the display height is y, the screen diagonal size is Sim, the screen ratio is 16:9, and one inch = 25.4 mm, the specific calculation formula is as follows:

[0113] Formula (1) x^2+y^2=z^2;

[0114] Formula (2)x / y=16 / 9;

[0115] Formula (3) x = 16y / 9;

[0116] By substituting formula (3) into formula (1), we obtain formula (4): (16y / 9)^2+y^2=Sim^2.

[0117] Solve y = round(sqrt(pow(Sim,2)*(81 / 337)),3), where pow(Sim,2) means calculating the square of Sim, pow is a function used to calculate the exponential power of a given base, which is the square of Sim in this case, and sqrt is a function for finding square roots. In this expression, it is used to calculate the square root of the result in the brackets, 81 / 337 is the scale factor, and the round function is used to round numbers. The 3 here indicates that the result returned by the function should be retained to the third decimal place.

[0118] Thus we get y=sqrt(pow(Sim,2)*(81 / 337)), x=(16*y) / 9.

[0119] Then, the first outline length and the second outline length of the display group are calculated (that is, the total width and total height of the connected screen are calculated). The calculation formula of the first outline length can be:

[0120] CW=N1*X1+BS

[0121] Among them, CW is the first contour length, N1 is the first number, X1 is the first display screen width, BS is the first interval length, BS = (N1-1)*(A+B), A+B is the adjacent interval width between two adjacent outer contour displays, A and B are the first border widths of two adjacent outer contour displays respectively, and A and B may be different or the same.

[0122] The calculation formula of the second contour length can be:

[0123] CH=N2*X2+BH

[0124] Wherein, CH is the second contour length, N2 is the second number, X2 is the display screen height, BH is the second interval length, BH=(N2-1)*(C+D), C+D is the adjacent interval width between two adjacent outer contour displays, C and D are respectively the first border widths of the two adjacent outer contour displays, and C and D may be different or the same. It should be noted that the first number and the second number may be the same or different, and there is no limitation here, depending on the target combination mode of the display group.

[0125] Then, calculate the first ratio of the image to be displayed and the total width of the display, that is, the width of the image to be displayed / the total width of the screen (that is, the first contour length); calculate the second ratio of the image to be displayed and the total height of the display, that is, the height of the image to be displayed / the total height of the screen; calculate the width of a single display screen occupied by the image resource, that is, the width of the target display screen*the first ratio; calculate the height of a single display screen occupied by the image resource, that is, the height of the target display screen*the second ratio; take the upper left corner point of each target display screen as the starting position, and perform image cropping according to the width of a single display screen occupied by the image resource and the height of a single display screen occupied by the image resource, please refer to Figure 7 , Figure 7A schematic diagram of a scene for cropping an image to be displayed (i.e., determining the combined size information of a display group based on each target size information; determining the display ratio between the image to be displayed and the display group based on the image size information and the combined size information; for any display to be processed among multiple target displays, determining the resource size information corresponding to the display to be processed based on the display ratio and the size information to be processed, wherein the size information to be processed is the target size information of the display to be processed; obtaining a display combination mode of the multiple target displays, and determining the display position information of the display to be processed in the display group based on the display combination mode and each target size information, wherein the display to be processed is the display of the display to be processed; determining a display sub-image of the display to be processed in the image to be displayed according to the display position information and the resource size information).
