In this step, the hardware processor 130 obtains a window image transmitted by the window image device 140 (through the fourth signal line 142) and a desktop image transmitted by the desktop image device 120 (through the third signal line 122). The hardware processor 130 performs a separation process on the desktop image including the mouse image to obtain a separated mouse image.
The window images are images, videos and the like displayed in large-screen windows such as a splicing wall and a splicing screen; the desktop image is an image which is obtained through a desktop signal and is used as a large-screen display desktop. In the embodiment of the present invention, the desktop image device 120 is configured to process a desktop image and acquire mouse operation information for operating a window image.
Alternatively, the image corresponding to the mouse image in the separated desktop image may replace pixels of the image corresponding to the mouse image with pixels of a nearby image according to surrounding pixels. If the window image is on the image corresponding to the mouse image, no processing may be performed. Other processing methods are also possible as long as the entire display of the separated desktop image is not affected.
In order to facilitate the window operation and the control of the whole large-screen window, a mouse (input device) is connected to the desktop image device 120, and the desktop image device 120 obtains the operation information of the window image and controls the window image and the mouse image.

The mouse operation information is window control information which is input through a mouse connected to desktop image equipment when a user needs to control a window image, and the mouse operation information comprises information for controlling the window image and display of the mouse image.
The simulation window control is used for acquiring operation information of a window, and the simulation window control corresponds to the size and the position of the window image, namely the window image is overlapped with the simulation window control. If the simulation window control is displayed on a large-screen window, the window image can completely cover the simulation window control, so that the simulation window control can completely acquire information for operating the window image. Of course, the analog window control may not be displayed on the large-screen window, as long as the analog window control corresponds to the window image and can acquire the mouse operation information for controlling the window image and the mouse image. The simulation window control can be in various shapes such as a square shape or a circular shape.
And S140, controlling the display image of the front-end display device 110 according to the mouse control instruction so as to correspondingly adjust the window image.
In this step, after receiving the mouse control instruction sent by the background control device 150, the hardware processor 130 executes control on the window image 112 in the display image according to the mouse control instruction. Optionally, this step may also include control of the mouse image 113.

The association between the front-end screen mouse and the control equipment is established, and the front-end display of the desktop mouse and the front-end display of the window operation process can be realized.
In one embodiment, step S110 includes: and separating continuous pixel points with the same preset pixel values as those of the mouse image from the desktop image to obtain a separated mouse image.
Optionally, the desktop image and the mouse image may be separated by other manners, for example, an image with similarity to a preset shape of the mouse image higher than a certain threshold is separated from the desktop image, so as to obtain a separated mouse image.
The embodiment realizes the separation of the mouse image and the desktop image according to the difference between the desktop image and the mouse image.
In one embodiment, step S140 includes: when the mouse operation information detected by the desktop image device 120 through the analog window control is the adjustment operation information of the analog window control, the mouse control instruction is a control instruction of a window image in the display image of the front-end display device 110, and the size or the position of the window image in the display image of the front-end display device 110 is adjusted according to the mouse control instruction; when the mouse operation information detected by the desktop image device 120 through the analog window control is deletion operation information of the analog window control, the mouse control instruction is a control instruction of a window image in a display image of the front-end display device 110, and the window image in the display image of the front-end display device 110 is hidden according to the mouse control instruction.
Optionally, step S140 may further include control of the mouse image, namely: when the mouse operation information detected by the desktop image device 120 through the simulation window control is mouse movement operation information, the mouse control instruction is a movement control instruction for a mouse image in the display image of the front-end display device 110, and the position of the mouse image in the display image of the front-end display device 110 is moved according to the mouse control instruction. In this embodiment, the background control device 150 generates corresponding mouse control instructions for different mouse operation information to control the window image and the mouse image, and the process of controlling the window image and the mouse image is displayed through the front-end display device 110. Front-end display of window operations is achieved.
Optionally, the window image may also be a video image, and the implementation process of step S140 may also be: and when the mouse operation information is pause operation information of the analog window control, continuously displaying the current window image or not updating the window image according to the mouse control instruction. The implementation process can also be other implementation processes for controlling window images and videos.
In one embodiment, the window control method further includes the steps of: and adjusting the window image according to the size information of the window image and the desktop image. Optionally, the adjusting of the window image may be moving, zooming, and the like of the window image and an overlapping process of overlapping the window image on the desktop image; or may be a related process to the desktop image. After the desktop image and the window image complete the relevant operation, the separated mouse image is superposed to the processed image again and output. The window image is adjusted before the window image is displayed, the window image display effect is improved, and the problems of window image inclination, improper size and the like can be prevented.
Fig. 4 is a schematic flowchart of a window control method according to a second embodiment, which is described in this embodiment by taking a desktop image device as an example, and the window control method provided in the embodiment mainly includes steps S210 to S230, which are described in detail as follows:
s210, acquiring windowing information of a window image from the background control equipment 150, and drawing a corresponding simulation window control according to the windowing information to obtain a desktop image; the desktop image also comprises a mouse image.
In this step, after the background control device 150 sends the windowing information of the window image to the desktop image device 120, the desktop image device 120 draws a simulated window control corresponding to the window image according to the windowing information, so as to obtain the desktop image.
Alternatively, the process of drawing the corresponding simulated window control may be before the hardware processor 130 sends the display image to the front-end display device 110, or may be after the hardware processor 130 sends the display image to the front-end display device 110. The simulated window control may be displayed through the front-end display device 110, or may not be displayed, and if the simulated window control is displayed, the display of the simulated window control on the front-end display device is completely covered by the window image corresponding to the simulated window control, and therefore is invisible.
S220, sending the desktop image including the mouse image to the hardware processor 130, so that the hardware processor 130 separates the mouse image from the desktop image and superimposes the separated mouse image on the synthesized image to obtain a display image of the front-end display device 110; the composite image is composed of a desktop image and a window image superimposed thereon.
In this step, the desktop image device 120 sends the desktop image including the mouse image to the hardware processor 130, so that the hardware processor 130 realizes the processes of mouse separation and image superposition to obtain the composite image to be displayed (i.e., the aforementioned display image).
S230, detecting local mouse operation information through the simulation window control, and sending the mouse operation information to the background control device 150, so that the background control device 150 generates a corresponding mouse control instruction according to the mouse operation information and sends the mouse control instruction to the hardware processor 130; the hardware processor 130 is configured to control a display image of the front-end display device 110, so that the window image is adjusted accordingly.
The step is realized by the process of acquiring the mouse operation information through the simulation window control. The desktop image device 120 is connected to a mouse, and when the user operates the window image through the mouse, the desktop image device 120 obtains local mouse operation information through the simulated window control and sends the mouse operation information to the hardware processor 130 to implement front-end display of the window operation process.
The embodiment establishes the association between the front-end screen mouse and the control equipment, can realize the front-end display of the desktop mouse, and enables a user to intuitively sense the operation of the relevant window through the large-screen desktop mouse. Taking the spliced wall as an example, an operation interface is provided for a user on the spliced wall through a mouse image on a desktop image, so that the user can realize various window operations directly on the spliced wall without going to the background control equipment 150 for operation, then looking at whether the image on the spliced wall is correct or not, and then determining whether the step of adjusting the image needs to be repeated or not.
In an embodiment, the windowing information includes size and position information of the window image. Further, step S210 includes: and drawing a simulation window control on the desktop image according to the size and the position information. According to the embodiment, the simulation window control is drawn according to the size and the position information of the window image, so that the operation on the window image can be acquired through the simulation window control.
Optionally, the simulated window control may also be drawn in a desktop window instead of only on a desktop image, and the simulated window control is used to obtain operation information about the window image and the mouse image, and the operation information may be obtained by the simulated window control.
In one embodiment, the window control method further includes the steps of: judging whether pixel points with the same value as the preset pixel values of the mouse image exist in the pixel points of the desktop image; and if so, replacing the pixel value of the pixel point with other pixel values.
The embodiment realizes the process of desktop image preprocessing. Alternatively, the mouse image is generally a white background black frame, and therefore, the black color of the mouse may be set to (r, g, b) ═ 0,0,0, and the white color may be set to (r, g, b) ═ 255, 255. When there are full black and full white pixel values on the desktop image, i.e., other pixel values in the desktop image are the same pixel values as the mouse image, then the full black and full white pixel values are replaced with other pixel values (e.g., neighboring values): (0,0,0) → (1,1,1), (255,255,255) → (254,254,254), and after completing the above processing, the desktop image device 120 transmits the desktop image including the mouse graphics to the hardware processor 130. Alternatively, the preset pixel value of the mouse image may be other pixel values, for example, the mouse image may be a color image or a gray image. The desktop image preprocessing process can also be realized in other ways, for example, by using a pattern recognition technology, an image with similarity higher than a certain threshold value with a preset shape of the mouse image is marked, and the mouse image and the desktop image are distinguished. The present embodiment distinguishes the mouse image from the desktop image, which facilitates the hardware processor 130 to separate the mouse image from the desktop image.
In one embodiment, the window control method further includes the steps of: and adjusting the simulation window control according to the mouse operation information. In this embodiment, the simulated window control is adjusted according to the mouse operation information, so that the simulated window control corresponds to the window image.
Fig. 5 is a schematic flowchart of a window control method according to a third embodiment, where the window control method provided in the embodiment mainly includes steps S310 to S350, and the following is described in detail:
s310, the desktop image equipment acquires windowing information of a window image from the background control equipment, draws a corresponding simulation window control according to the windowing information, and obtains a desktop image which also comprises a mouse image; and sending the desktop image containing the mouse image to a hardware processor.

S330, the desktop image equipment detects local mouse operation information through the simulation window control and sends the mouse operation information to background control equipment; and adjusting the simulation window control according to the mouse operation information.
And S340, the background control equipment generates a mouse control instruction according to the mouse operation information and sends the mouse control instruction to the hardware processor.
And S350, controlling the display image of the front-end display equipment by the hardware processor according to the mouse control instruction so as to correspondingly adjust the window image.
According to the embodiment, the association between the front-end screen mouse and the control equipment is established, and the front-end display of the desktop mouse and the front-end display of the window operation process can be realized.
In order to better understand the above method, an application example of the window control method of the present invention is described in detail below, and the implementation process is specifically as follows:

If a pixel point with the same color value as the mouse exists on the desktop image, the pixel value of the pixel point is replaced by an adjacent value, for example, (0,0,0) is replaced by (1,1,1), and (255 ) is replaced by (254,254,254). After the above processing, the desktop image device 120 sends the desktop image containing the mouse graphics to the hardware processor 130.
2) And (3) separating the mouse, detecting the pixel value of the desktop image by the hardware processor 130, and when the same continuous pixel points with the preset pixel values (r, g and b) (0,0,0) or (r, g and b) (255,255 and 255) of the mouse image exist, extracting and identifying the continuous pixel points, completing the separation of the mouse, and obtaining the separated mouse image.
