Step 102: acquiring attribute information of an image to be displayed and resolution information of a display screen divided into a plurality of screen areas.

In an embodiment of the present specification, the image to be displayed is an image that needs to be displayed in the display screen, and the attribute information of the image to be displayed specifically refers to resolution information, occupied storage space information, and the like of the image to be displayed; the display screen divided into the plurality of screen areas is specifically a screen for displaying the image to be displayed, the display screen is divided into the plurality of screen areas so that the image to be displayed, which needs to be displayed, in the display screen can be rendered through the plurality of rendering terminals, the rendering of the image to be displayed through the plurality of rendering terminals is performed because the definition of the image to be displayed is high, and the image to be displayed, which is rendered through a single rendering terminal, cannot be output to the display screen for displaying, so that the display screen is divided into the plurality of screen areas, each screen area corresponds to one rendering host, only a part of the image to be displayed is displayed in each screen area, and the displayed images are formed by the plurality of parts of the image to be displayed, which are displayed through the plurality of screen areas, so that the image to be displayed is completely displayed in the display screen.

When a user watches an image through a screen, the definition of the image is not only influenced by the resolution of the display screen, but also influenced by the highest-definition image which can be output by the rendering terminal, namely, if the user needs to watch the image with high enough definition, the definition of the display screen is high enough, and the definition of the image output by the rendering terminal can be realized under the condition that the definition of the image is high enough.

Based on this, in the process of rendering the image to be displayed through the plurality of rendering terminals, the plurality of rendering terminals can render the image to be displayed simultaneously by using the nDisplay technology in the UE4 engine, so as to display the image to be displayed in the display screen, in the process of displaying the image to be displayed through the display screen, the image to be displayed is displayed through a plurality of screen areas divided by the display screen, and in the process of displaying the image to be displayed in each screen area, the display content in the image to be displayed may repeatedly appear in a plurality of adjacent screen areas, which is visible.

In the image display method based on the display screen provided by the specification, in order to enable the image to be displayed to be completely adapted in the display screen and avoid the situation that a plurality of screen areas repeatedly display the image to be displayed, the image to be displayed is adapted to the display screen, the adaptation multiple of the image to be displayed is determined, the image to be displayed is rendered through the rendering terminal corresponding to each screen area, the offset of the image to be displayed in each screen area is determined according to the adaptation multiple and the coordinate information of each screen area in the display screen, the image to be displayed is moved in each screen area according to the offset, the image to be displayed in each screen area can be spliced into the image to be displayed, the image to be displayed can be rendered through the rendering terminals, and the definition of the image to be displayed on the display screen is high, and when the image to be displayed is displayed through each screen area, the situation that the image to be displayed is repeatedly displayed in each screen area is avoided, so that the image to be displayed can be completely displayed through the display screen.

Before the resolution information of the display screen is obtained, in one or more embodiments of this embodiment, because there is an output bottleneck problem in outputting the to-be-displayed image, the to-be-displayed image needs to be rendered simultaneously through a plurality of rendering terminals, and the to-be-displayed image can be displayed, and before the to-be-displayed image is rendered through the plurality of rendering terminals, the display screen needs to be divided according to the plurality of rendering terminals, and each rendering terminal corresponds to a screen area divided in the display screen, and the specific implementation manner is as follows:

Specifically, the attribute information of the rendering terminals specifically refers to the number of the rendering terminals and the highest-definition image information that can be output by each rendering terminal, the display screen is divided according to the number of the rendering terminals and the output information of each rendering terminal, and the rendering terminals are determined to correspond to each screen area in the divided display screen one to one; the rendering terminal can be a computer host.

For example, if the resolution of a certain display screen is 8k, and any one of 4 existing computer hosts can only output images with 2k resolutions, and any one of the 4 existing computer hosts cannot output images with 8k resolutions, the display screen needs to be divided into a plurality of screen areas, and each screen area is rendered by one computer host, so that the images can be displayed in the 8k display screen by combining and outputting the output of the plurality of computer hosts, and the display screen is divided into 4 screen areas according to the number of the computer hosts, and each screen area is rendered by the computer host capable of outputting images with 2k resolutions.

In the process of dividing the display screen according to the rendering terminals, if there may be a case where the resolution of the output image of each rendering terminal is not consistent, the display screen may be divided irregularly, that is, the rendering terminal with the lower resolution of the output image may divide a smaller screen area in the display screen, and the rendering terminal with the higher resolution of the output image may divide a larger screen area in the display screen.

Under the condition that a single rendering terminal cannot directly output the image to be displayed in the display screen, the display screen can be divided into a plurality of screen areas according to the plurality of rendering terminals, so that each screen area corresponds to each rendering terminal, and under the condition that the image to be displayed is displayed through the display screen subsequently, the image to be displayed can be rendered by each rendering terminal aiming at each screen area, so that the image to be displayed with higher resolution can be output through the display screen.

Step 104: and calculating the adaptation multiple of the display screen and the image to be displayed according to the attribute information and the resolution information.

Specifically, on the basis of the acquired attribute information of the image to be displayed and the resolution information of the display screen, further, the display screen is calculated to display the image to be displayed according to the attribute information and the resolution information, and the multiple of the image to be displayed, which needs to be changed, is the adaptation multiple;

on the basis, under the condition that the image to be displayed is displayed through the display screen, the situation that the display screen is not matched with the image to be displayed possibly exists, namely, the situation that the display screen is large and the image to be displayed is small and not matched, or the situation that the display screen is small and the image to be displayed is large and not matched exists; at this time, the image to be displayed needs to be adapted to the display screen, so that the image to be displayed can be completely displayed in the display screen.

In one or more embodiments of this embodiment, in the process of calculating the adaptation multiple, since the image to be displayed is not rendered, at this time, the resolution of the image to be displayed needs to be determined according to the attribute information of the image to be displayed, the resolution of the display screen needs to be determined according to the resolution information of the display screen, and then the adaptation multiple is calculated according to the resolution of the image to be displayed and the resolution of the display screen, which is specifically implemented as follows:

Specifically, in order to enable the image to be displayed to be adapted to the display screen, so that the image to be displayed can be completely displayed in the display screen, in the case that the resolution of the image to be displayed is inconsistent with that of the display screen, the image to be displayed needs to be enlarged or reduced, so that the image to be displayed can be completely displayed on the display screen;

based on this, before the image to be displayed is adapted to the display screen, an adaptation multiple needs to be calculated, the image resolution of the image to be displayed is determined according to the attribute information, the screen resolution of the display screen is determined according to the resolution information, the ratio of the image resolution to the screen resolution is calculated, and the ratio result is used as the adaptation multiple of the image to be displayed, which needs to be enlarged or reduced, to be adapted to the display screen;

the screen resolution specifically refers to the number of similar pixels in the horizontal direction and the vertical direction, for example, if the screen resolution is 920 × 1080, the number of pixels in the horizontal direction is 920, and the number of pixels in the vertical direction is 1080; the image resolution refers to the number of pixels in each inch of an image to be displayed, for example, if the image resolution is 1028 × 447, it indicates that the image is composed of 1028 × 447 pixels 459516, and the distribution of the pixels is 1028 pixels horizontally and 447 pixels vertically, which are uniformly distributed to form the image.

In specific implementation, under the condition that the image to be displayed is displayed through the display screen, if the image to be displayed needs to be displayed in a tiled manner in the display screen, the length size and the width size of the image to be displayed can be determined according to the image resolution, the length size and the width size of the display screen are determined according to the screen resolution, the ratio of the length size of the image to be displayed to the length size of the display screen is calculated to serve as a length adaptation multiple, the ratio of the width size of the image to be displayed to the width size of the display screen is calculated to serve as a width adaptation multiple, and the length adaptation multiple and the width adaptation multiple are used for determining the adaptation multiple of the image to be displayed and the display screen; in the subsequent adaptation process, the length size and the width size of the image to be displayed are amplified or reduced according to the length adaptation multiple and the width adaptation multiple;

under the condition that the image to be displayed is displayed through the display screen, if the image to be displayed needs to be displayed in the display screen according to the original proportion of the image to be displayed, the length size and the width size of the image to be displayed can be determined according to the image resolution, the length size and the width size of the display screen are determined according to the screen resolution, the ratio of the length size of the image to be displayed to the length size of the display screen is calculated to be used as a length adaptation multiple, the ratio of the width size of the image to be displayed to the width size of the display screen is calculated to be used as a width adaptation multiple, the length adaptation multiple and the width adaptation multiple are compared, if the length adaptation multiple is smaller than the width adaptation multiple, the length adaptation multiple is used as the adaptation multiple of the image to be displayed and the display screen, in the subsequent adaptation process, the length size and the width size of the image to be displayed are amplified or reduced according to the length adaptation multiple; and if the length adaptation multiple is larger than the width adaptation multiple, taking the width adaptation multiple as the adaptation multiple of the image to be displayed and the display screen, and amplifying or reducing the length size and the width size of the image to be displayed according to the width adaptation multiple in the subsequent adaptation process.

Referring to fig. 2, the display screen is shown in fig. 2(a), the display screen is a 4k resolution screen, that is, 4096 × 2160 resolution, a high-definition image with 885 ten thousand pixels can be viewed through the display screen, it is now required to display a frame of picture through the display screen, the frame of picture is shown in fig. 2(b), the frame of picture is 2048 × 1080 resolution, it is determined by the attribute information of the picture that the rendered picture is not consistent with the size of the display screen, the rendered picture is smaller than the display screen, the picture needs to be enlarged in a certain proportion to be adapted into the display screen, by calculating the ratio of the resolution of the display screen to the resolution of the picture, 4096 × 2160/2048 × 1080 is 4, so that the rendered picture needs to be enlarged 4 times to be completely exhibited in the display screen, the rendered display effect is shown in fig. 2(c), therefore, the adaptation multiple of the display screen and the frame is determined to be 4 times.

The method comprises the steps of determining an adaptation multiple of the image to be displayed, which is adapted to the display screen and needs to be amplified or reduced, by calculating the ratio of the image resolution of the image to be displayed to the screen resolution of the display screen, so that the rendered image to be displayed can be completely displayed in the display screen after the image to be displayed is rendered through a plurality of rendering terminals in the subsequent process.

Step 106: rendering the image to be displayed through a plurality of rendering terminals corresponding to the plurality of screen areas.

Specifically, on the basis of determining the adaptation multiple, the image to be displayed is loaded to the rendering terminals respectively for rendering, because each rendering terminal corresponds to one screen area, the image to be displayed is completely displayed in each screen area, and then the image to be displayed in each screen area is rendered through the rendering terminals, so that the image to be displayed in each screen area can be completely displayed;

based on this, in the process of rendering the image to be displayed through the rendering terminal, in order to enable the resolution of the image exhibited by each screen area to be consistent in the subsequent process of displaying the image to be displayed, the output results of the rendering terminals need to be adjusted, and since the output of the rendering terminals is limited by hardware, the resolution of the output image of each rendering terminal is fixed, and the resolution of the output image cannot be improved on the basis of limited hardware, the resolution of the output image of the rendering terminals needs to be adjusted according to the rendering terminal with the lowest resolution of the output image, so that the display effect of the finally rendered image to be displayed can be consistent.

Before the rendering the image to be displayed by the rendering terminals, in one or more embodiments of this embodiment, the image to be displayed needs to be loaded to the rendering terminal corresponding to each screen region for rendering, and the specific implementation manner is as follows:

Specifically, before the rendering of the image to be displayed by the rendering terminals, the image to be displayed needs to be loaded to the rendering terminals, so that the rendering terminals can render the image to be displayed completely, and the rendering is performed on each display screen, that is, the image to be displayed can be displayed completely in each display screen.

Before the rendering the image to be displayed by the rendering terminals, in one or more embodiments of this embodiment, in order to ensure that the resolution of the image to be displayed finally displayed in each display screen area is consistent, the resolution of the image to be displayed output by the rendering terminals needs to be controlled while rendering, and a specific implementation manner is as follows:

Specifically, the display screen is divided into a plurality of screen regions, and each of the screen regions belongs to a part of the display screen, so that the screen resolutions (DPI) of the screen regions are consistent;

based on this, acquiring the screen resolution (screen DPI) of the display screen, and determining the image resolution (image DPI) of the image to be displayed according to the attribute information, wherein the screen resolution specifically refers to the number of pixel points included in the display screen, and the image resolution specifically refers to the number of pixel points forming the image to be displayed; under the condition that the image resolution is greater than the screen resolution, the number of pixel points of the image to be displayed is greater than the number of pixel points in the display screen, and at the moment, if the image to be displayed is displayed through the display screen, the image to be displayed cannot be normally displayed; at this time, the image resolution of the image to be displayed needs to be reduced, the reduction degree can be adjusted according to the screen resolution, namely, the image resolution is adjusted to be consistent with the screen resolution, and when the image to be displayed is displayed through the display screen, pixel points in the display screen correspond to pixel points in the image to be displayed one by one;

under the condition that the image resolution is equal to the screen resolution, the number of the pixel points of the image to be displayed is equal to the number of the pixel points in the display screen, and at the moment, the image resolution does not need to be adjusted, and the subsequent processing process is carried out;

and under the condition that the image resolution is smaller than the screen resolution, indicating that the number of the pixel points of the image to be displayed is smaller than the number of the pixel points in the display screen, and at the moment, carrying out subsequent processing without adjusting the image resolution.

Referring to fig. 3, the display screen is as shown in fig. 3(a), the display screen is divided to obtain a screen area 1, a screen area 2, a screen area 3 and a screen area 4, the screen resolution is 96DPI, and each screen area corresponds to one rendering terminal, at this time, an image with an image resolution of 106DPI needs to be displayed in the display screen, the image resolution needs to be adjusted to be consistent with the screen resolution for rendering, the image resolution is determined to be 96DPI by adjustment, then, in order to be able to display the image in the whole display screen, the image is fully displayed in each screen area firstly, then, the image is magnified and adapted, and then, the image is displayed in the display screen, the image in the screen areas is rendered by each rendering terminal, and the display effect of the image in the

screen areas

1, 2, 3 and 4 is as shown in fig. 3(b), the image is fully displayed in screen area 1, screen area 2, screen area 3 and screen area 4.

Before the plurality of rendering terminals render the image to be displayed in each screen area, in order to achieve better effect of the finally displayed image to be displayed, the image resolution of the image to be displayed needs to be adjusted according to the screen resolution of the display screen, so that the finally displayed image to be displayed has better effect, and the plurality of rendering terminals completely render the image to be displayed in the plurality of screen areas, thereby facilitating the subsequent adaptation process of the image to be displayed.

Step 108: and adapting the rendered image to be displayed in the plurality of screen areas according to the adaptation multiple.

Specifically, after the images to be displayed are rendered through the rendering terminals, the rendered images to be displayed are adapted in the screen areas according to the adaptation multiples, that is, the images to be displayed are completely displayed in the screen areas at this time, in order to enable the screen areas to display a part of the images to be displayed, the images to be displayed are displayed through the display screen after being spliced, and the rendered images to be displayed in the screen areas need to be adapted, that is, the rendered images to be displayed in the screen areas are amplified.

In the process of adapting the images to be displayed in the multiple screen regions according to the adaptation multiple, in one or more embodiments of this embodiment, in order to avoid occurrence of a situation that an adjacent screen region repeatedly displays the images to be displayed when shifting the images to be displayed in each screen region in the subsequent process, the images to be displayed in each screen region need to be adapted based on the reference coordinates, and when the shifting process is performed, the specific implementation manner is as follows:

Specifically, a reference coordinate is configured for an image to be displayed in each rendered screen area, the reference coordinate is used for determining a fixed point for adapting the image to be displayed, and the image to be displayed is adapted based on the fixed point, so that the image to be displayed after being adapted in each screen area is convenient for calculating an offset in the subsequent process; in the process of configuring the reference coordinates, a plane coordinate system can be established for the image to be displayed, the same point of the image to be displayed in each screen area is selected as a coordinate origin, and then the reference coordinates are determined based on the established coordinates.

Based on the reference coordinates, the rendered images to be displayed in the multiple screen areas are adapted according to the adaptation multiples.

Following the above example, as shown in fig. 3(b), it is determined that the image to be displayed is completely displayed in each screen area, and it is determined that the image is adapted to the display screen divided into screen area 1, screen area 2, screen area 3 and screen area 4 with an adaptation factor of 4, and it is determined that the image is enlarged in each screen area with an enlargement factor of 4, then a reference coordinate is configured for the image, the reference coordinate (0, 0) is the upper left corner of the image, the image in each screen area is enlarged by 4 using the reference coordinate as a fixed point, the enlarged display effect is as shown in fig. 4, see fig. 4, where the display contents in screen area 1, screen area 2, screen area 3 and screen area 4 are the same, and the portion outside the screen area indicates that rendering by the rendering terminal has been completed but is not displayed in the screen area, in this case, it is necessary to perform offset processing on the image in each screen area so as to realize complete presentation of the image through the presentation screen.

Before the images to be displayed which are rendered in each screen area are configured, the images to be displayed which are displayed in each screen area can form a display screen to be displayed completely, the situation that the images to be displayed are displayed repeatedly before each screen area is avoided, reference coordinates are configured for the images to be displayed in each screen area, the reference coordinates are used as fixed points to perform adaptation according to the adaptation multiples, and the images to be displayed in each screen area can be subjected to offset processing more simply and conveniently.

Step 110: and calculating the offset of the image to be displayed in the plurality of screen areas according to the adaptation result and the coordinate information of the plurality of screen areas in the display screen.

Specifically, after the rendered image to be displayed is adapted in each screen area, the offset of the image to be displayed in the plurality of screen areas needs to be calculated according to the adaptation result and the coordinate information of each screen area in the display screen; the offset specifically refers to a vector of change of the image to be displayed in each screen area, namely a coordinate distance of the image to be displayed needing to move horizontally and a coordinate distance of the image to be displayed needing to move vertically in each screen area;

based on this, the offset of the image to be displayed in the multiple screen areas is calculated to enable the contents displayed in the multiple screen areas to be spliced to form the image to be displayed, and in order to avoid the situation that the displayed contents in each screen area are repeated, the offset of the image to be displayed needs to be determined according to the coordinate information of each screen area in the screen area.

On the basis of adapting the to-be-displayed image in the multiple screen regions according to the adaptation multiple, in one or more embodiments of this embodiment, a specific implementation manner of calculating the offset is as follows:

Specifically, the area coordinates of each divided screen area relative to the display screen are determined according to the coordinate information, the area coordinates may be determined after a plane coordinate system is established based on the display screen, specifically, the plane coordinate system is established according to the display screen, then the coordinates of four vertexes of each screen area in the plane coordinate system are determined, and the area coordinates of one screen area are determined based on the four coordinates;

based on this, image coordinates are configured for the adapted image to be displayed in each screen area according to the adaptation result, that is, the image coordinates are used for determining the distance that the image to be displayed needs to move relative to the screen area, the image offset of the image to be displayed in each display screen is calculated based on the image coordinates and the area coordinates, and the image offset is used as the offset of the image to be displayed in the plurality of screen areas.

For example, the presentation screen is divided into 4 screen regions, screen region 1, screen region 2, screen region 3, and screen region 4, and it is determined by the coordinate information that screen region 1 is composed of four coordinates of (0, 0), (0, 10) (-10, 0), (-10, 10), screen region 2 is composed of four coordinates of (0, 0), (0, 10) (10, 0), (10, 10), screen region 3 is composed of four coordinates of (0, 0), (0, -10) (-10, 0), (-10 ), and screen region 3 is composed of four coordinates of (0, 0), (10, 0) (0, -10), (10, -10);

the four screen regions are equal in size, and the displayed images adapted in the screen regions are also equal, and are all the upper left corner parts of the images, the size of each screen region is 10 × 10, and the size of each display screen is 20 × 20, so that the four screen regions respectively display the 10 × 10 parts of the images, and the images can be completely displayed through the display screens, at the moment, the four screen regions all display the same image parts, the offset of the images in each screen region needs to be calculated, and then the images are subjected to offset processing according to the offset;

based on this, by the area coordinates of the respective screen areas and the image coordinates configured for the image, the amount of shift of the image with respect to the presentation screen is calculated as 0 unit in the horizontal direction and 0 unit in the vertical direction in the screen area 1, the amount of shift of the image with respect to the presentation screen is calculated as-10 units in the horizontal direction (10 units of shift of the image with respect to the origin of coordinates) and 0 unit in the vertical direction in the screen area 2, the amount of shift of the image with respect to the presentation screen is calculated as 0 unit in the horizontal direction and 10 units in the vertical direction (10 units of shift of the image with respect to the origin of coordinates) in the screen area 3, the amount of shift of the image with respect to the presentation screen is calculated as-10 units in the horizontal direction (10 units of shift of the image with respect to the origin of coordinates) and 10 units in the vertical direction (10 units of shift of the image with respect to the origin of coordinates), the amount of shift of the image with respect to the presentation screen is determined based on the amount of shift of the image in the horizontal direction and the vertical direction in each screen region.

The offset of the image to be displayed in the screen areas is calculated through the coordinate information, the offset distance of the image to be displayed relative to the screens can be determined more accurately, the situation that the image to be displayed is repeatedly displayed in each screen area is avoided, and the optimal splicing effect among the screen areas can be achieved.

On the basis of calculating the offset according to the adaptation result and the coordinate information, further, in one or more embodiments of this embodiment, it is required to detect whether the image to be displayed is added to the visual window, and then the image to be displayed can be displayed in the plurality of screen areas, and a specific implementation manner is as follows:

if yes, loading the rendered image to be displayed to the plurality of screen areas based on the parameters of the visual window;

if not, no treatment is needed.

Specifically, whether the image to be displayed in the multiple screen areas is added to the visual window is detected, where the visual window specifically refers to a ViewPort in the UE4, and only when the image to be displayed is added to the visual window (ViewPort), subsequent display can be performed;

based on this, if it is detected that the to-be-displayed image in the rendered multiple screen areas is added to the visual window, it indicates that the to-be-displayed image can be subsequently displayed through the display screen, and in this case, the rendered to-be-displayed image needs to be loaded to the multiple screen areas according to the parameters of the visual window; if it is detected that the to-be-displayed images in the rendered screen areas are not added to the visual window, which indicates that the to-be-displayed images are not adapted completely, no processing is required.

Step 112: and displaying the image to be displayed through the plurality of screen areas divided by the display screen based on the offset.

Specifically, on the basis of calculating the offset according to the adaptation result and the coordinate information, the image to be displayed may be subjected to offset processing based on the offset, and after the image to be displayed is offset, the image to be displayed is displayed through the plurality of screen areas, so that the image to be displayed is completely displayed in a display screen, and the image to be displayed is rendered by a plurality of rendering terminals at the same time.

In the above technology for determining the offset of the image to be displayed with respect to the screen area through calculation, in one or more embodiments of this embodiment, in a process of displaying the image to be displayed, an offset process needs to be performed according to the offset, and the image to be displayed after the offset process can be displayed, which is specifically implemented as follows:

Specifically, the image to be displayed needs to be subjected to offset processing relative to each screen area, and offset distances of the image to be displayed in the screen areas are different, so that the image to be displayed in each screen area has a corresponding offset, the image to be displayed needs to be subjected to offset processing according to the corresponding offset in the offset processing process, and based on the offset processing, the image to be displayed can be displayed through the plurality of screen areas according to the offset processing result.

In the process of performing offset processing on the image to be displayed based on the offset amount, in one or more embodiments of this embodiment, a specific offset processing process is as follows:

Specifically, first, reference points of the image to be displayed in the plurality of screen areas are determined, the reference points are consistent in each screen area, and the image to be displayed in each screen area is shifted according to the coordinate information corresponding to the screen area and the offset amount under the condition that the coordinate corresponding to the reference point is determined.

Still taking the case that the presentation screen is divided into 4 screen regions, which are screen region 1, screen region 2, screen region 3 and screen region 4, respectively, as an example, the offset processing procedure is described, it is determined from the calculation that the offset amount of the image with respect to the presentation screen in the screen region 1 is 0 unit in the horizontal direction and 0 unit in the vertical direction, the offset amount of the image with respect to the presentation screen in the screen region 2 is-10 units in the horizontal direction (10 units of leftward movement of the image with respect to the origin of coordinates), 0 unit in the vertical direction, 0 unit in the horizontal direction and 10 units in the vertical direction (10 units of upward movement of the image with respect to the origin of coordinates) in the screen region 3, 10 units in the horizontal direction (10 units of leftward movement of the image with respect to the origin of coordinates) in the screen region 4, 10 units in the vertical direction (the image is moved up 10 units with respect to the origin of coordinates);

based on this, referring to fig. 5, the image is subjected to the shift processing based on the shift amount, the image is not subjected to the shift processing in the screen region 1 as shown in fig. 5(a), the image is moved leftward in the screen region 2 by 10 units in accordance with the shift amount in the horizontal direction as shown in fig. 5(b), the image is not subjected to the shift processing in the screen region 3 by the shift amount in accordance with the horizontal direction as shown in fig. 5(c), the image is moved upward by 10 units in the vertical direction, the image is moved leftward in the screen region 4 by 10 units in accordance with the shift amount in accordance with the horizontal direction as shown in fig. 5(d), the image portions in the screen region 1, the screen region 2, the screen region 3 and the screen region 4 are portions which are finally required to be presented in the screen region, and the effect of finally presenting the image by presenting the screen is shown in fig. 5(e), the image is completely presented in the presentation screen divided into screen area 1, screen area 2, screen area 3 and screen area 4.

In addition, under the condition that the screen area is divided into a plurality of irregular screen areas, the image to be displayed can still be accurately subjected to offset processing according to the offset, so that the image to be displayed is completely displayed in the display screen;

based on this, referring to fig. 6, by dividing the presentation screen irregularly into a screen area 1, a screen area 2, a screen area 3 and a screen area 4, as shown in fig. 6(a), the divided presentation screen is calculated to determine that the amount of shift of the image in the screen area 1 is 0 unit in the horizontal direction and 0 unit in the vertical direction, the amount of shift of the image with respect to the presentation screen is-6 units in the horizontal direction (6 units of shift of the image to the left with respect to the origin of coordinates) and 0 unit in the vertical direction in the screen area 2, the amount of shift of the image with respect to the presentation screen is 0 unit in the horizontal direction and 10 units in the vertical direction (10 units of shift of the image with respect to the origin of coordinates) in the screen area 3, and the amount of shift of the image with respect to the presentation screen is-10 units in the horizontal direction (10 units shift of the image to the left with respect to the origin of coordinates) in the screen area 4, 10 units in the vertical direction (the image is moved up 10 units with respect to the origin of coordinates);

the result of the image being subjected to the offset processing with respect to the screen region 1 is shown in fig. 6(c), the result of the image being subjected to the offset processing with respect to the screen region 2 is shown in fig. 6(d), the result of the image being subjected to the offset processing with respect to the screen region 3 is shown in fig. 6(e), the result of the image being subjected to the offset processing with respect to the screen region 4 is shown in fig. 6(f), and the final display effect after the offset processing is shown in fig. 6 (b).

The image to be displayed is subjected to offset processing relative to the screen areas through the offset, so that the image to be displayed can be displayed completely through the display screen even under the irregular condition that the display screen is divided into the screen areas, the display is finished by rendering each screen area through a plurality of rendering terminals, and the image to be displayed can be displayed through the display screen under the irregular condition that the screen is divided under some special scenes.

The image display method based on the display screen provided by the specification comprises the steps of fitting an image to be displayed with the display screen, determining the fitting multiple of the image to be displayed, rendering the image to be displayed respectively through the rendering terminal corresponding to each screen area, determining the offset of the image to be displayed in each screen area according to the fitting multiple and the coordinate information of each screen area in the display screen, moving the image to be displayed in each screen area according to the offset, splicing the images displayed in each screen area into the images to be displayed, rendering the image to be displayed through a plurality of rendering terminals, realizing that the definition of the image to be displayed on the display screen is higher, and avoiding the occurrence of the repeated condition of displaying the image to be displayed in each screen area when the image to be displayed is displayed in each screen area, the image to be displayed can be completely displayed through the display screen, and even under the condition that the display screen is divided into a plurality of irregular screen areas, the image to be displayed can still be completely displayed.

In one or more embodiments of this embodiment, a specific implementation manner of adjusting the screen resolution is as follows:

Specifically, before the rendering terminals render the image to be displayed, screen resolution adjustment is required, because the screens forming the display screen are all independent screens, and the screen resolution of each screen may be different, and in the case that the screen resolutions of each screen are different, in order to make the effects of the parts of the image to be displayed by the screens consistent, the screen resolutions of the screens are required to be adjusted to be consistent, and because the screen resolutions of the screens depend on hardware reasons, the higher screen resolution adjustment is required to be adjusted according to the lowest screen resolution among the screens, for example, the screen resolution of the screen 1 is 100 ten thousand pixels, the screen resolution of the screen 2 is 200 ten thousand pixels, the screen resolution of the screen 3 is 400 ten thousand pixels, and in the case that the display screen formed by the screen 1, the screen 2 and the screen 3 displays the image to be displayed, the screen resolutions of the screen 2 and the screen 3 need to be adjusted to be consistent with the screen resolution of the screen 1, so that the finally displayed image to be displayed can be consistent.
