Example 1

According to an embodiment of the present invention, there is provided a screen control method, it should be noted that the steps shown in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.

Fig. 1 is a flowchart of a screen control method according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:

step S102, under the condition that a target event is detected in a preset range of a large screen, position information of a target area in a first image displayed in the large screen is obtained.

The preset range in the above steps may be a range in which content displayed on a large screen can be viewed, or a range in which a peek event is likely to occur. The target event may refer to a suspected peeping event, such as, but not limited to, a peeping screen by an illegal person, a peeping screen by a shooting tool, and the like. The first image may be an image currently displayed in a large screen, which is changed in real time. The target area may be a sensitive area that is not desired to be peeped or candid, such as an area containing core information of an enterprise, or an operation area of core software, but is not limited thereto.

The target application may be an application that is specified in advance by a user and is regarded as a sensitive application. The target elements may be user-defined sensitive elements including, but not limited to, text, pictures, videos, and the like. As shown in fig. 2, both the sensitive application display area and the sensitive element display area may be marked as sensitive areas.

In an optional embodiment, whether a suspected peeping event occurs may be detected by shooting an image within a preset range and further by means of image recognition. In the case that the suspected peeping event is determined to occur, in order to realize the peeping prevention function, whether the target area is included or not can be judged by identifying the first image currently displayed on the large screen, and if the target area is included in the first image, the position coordinates of the target area in the whole image can be determined.

And step S104, determining a target screen corresponding to the target area based on the position information of the target area, wherein the large screen is formed by splicing a plurality of screens.

It should be noted that the large screen is formed by splicing a plurality of screens, and the first image displayed in the large screen is obtained by splicing the sub-images displayed in each screen, so that the image to be displayed can be divided in advance, and the corresponding sub-images are displayed by each screen.

In order to realize the peep-proof function, if the display of the image of the whole large screen is stopped, the control process is complicated, and the viewing experience of other people is influenced. In an alternative embodiment, in order to avoid the above situation, it may be determined which screen or screens the target area is displayed on based on the position information of the target area, so as to determine that the screen displaying the target area is the target screen, and implement the peep-proof function by controlling the target screen to stop displaying the image.

And step S106, controlling the target screen to display a preset image.

The preset image in the above steps may be a preset replacement image, and the image may be a solid background image, or may be a specific image, but is not limited thereto.

In an optional embodiment, in order to avoid the information of the sensitive area from being leaked, when a suspected peeping event occurs, the display of the image in the target screen may be stopped, and the target screen is controlled to display a preset image, so that the user cannot see the information of the sensitive area on the large screen.

According to the scheme provided by the embodiment of the invention, under the condition that the target event is detected in the preset range of the large screen, the position information of the target area in the first image displayed in the large screen is obtained, the target screen corresponding to the target area is determined based on the position information of the target area, the target screen is controlled to display the preset image, and the image of the target area is not displayed any more, so that a user cannot view the information of the sensitive area in the large screen, the technical effects of avoiding information leakage and improving the safety of the large screen are achieved, and the technical problem of low safety of the large screen in the related technology is solved.

In the whole large-screen system, each screen can be connected with an image server through an R end, at least one image source device can be connected with the image server through an S end, the S end is used for collecting display images of the image source device, and the R end is used for controlling the screen to display the images.

In an alternative embodiment, a list of applications to be listened to may be set in advance at the S-side, where the list is an interface provided to the user, and the user may add a specific sensitive application to the list. The S terminal monitors the application in the application list while acquiring the display image of the image source equipment, and when the application in the list is opened, the window position information of the application can be acquired in real time, and the window position information of the sensitive application and the acquired image data of the display image are sent to the image server together, so that the image server can determine the display area of the sensitive application.

In an alternative embodiment, the sensitive element can be customized by a user, and is recognized by an encoder at the S terminal, and when the sensitive element is recognized, the display area of the sensitive element can be determined.

The preset image segmentation manner in the above step may be determined according to a combination manner of multiple screens, for example, as shown in fig. 3, for a large screen composed of four screens, the preset image segmentation manner may be "tian" font, where R1 corresponds to a sub-image at the upper left corner after segmentation, R2 corresponds to a sub-image at the upper right corner after segmentation, R3 corresponds to a sub-image at the lower left corner after segmentation, R4 corresponds to a sub-image at the lower right corner after segmentation, screen 1 is connected to R1, screen 2 is connected to R2, screen 3 is connected to R3, and screen 4 is connected to R4.

In an alternative embodiment, the first image displayed in the large screen may be divided based on a combination manner of the plurality of screens to obtain sub-images displayed by each screen, and after the position information of the target area is determined, which sub-image or sub-images the target area is located in may be determined, so that which screen or screens the target area is displayed by may be determined.

The receiving end in the above steps may be an R end of the control screen, and the target receiving end may be a target R end.

In an optional embodiment, the image server may discard the image data of the sub-image to be sent to the target R terminal, send the image data of the preset image to the target R terminal, and the target R terminal decodes the image data of the preset image and displays the decoded image data on a corresponding screen, so that the screen does not display the sub-image of the original display image any more, and thus information of the sensitive region is not leaked.

It should be noted that the sub-image to be sent to the target R end includes a sensitive area.

In an optional embodiment, a camera mounted on the large screen may be used to acquire a second image within a preset range, and the acquired second image is sent to the image server, and the image server may determine whether a suspected peeping event occurs at present according to the second image.

It should be noted that the camera is usually arranged on the front panel of the large screen, or a separate camera is used to be placed around the large screen. The camera can shoot pictures in a certain range in front of the large screen by adjusting the position of the camera, and a second image is obtained.

It should be further noted that the camera acquires the second image in real time, the image server judges whether a suspected peeping event occurs in real time, and if it is determined that the suspected peeping event does not occur, the above steps may be repeated.

The first object in the above steps may refer to a user viewing a large screen, and the target object may refer to a legal user viewing the large screen, for example, the target object may be a legal user or a legal viewer, but not limited thereto. The first behavior mentioned above can be, but is not limited to, peeping a large screen.

In an optional embodiment, the identity information of each user in the second image can be identified through AI algorithm identification, whether other people exist in the second image besides the legal user is determined, if the other people exist, the actions, the eyes, the positions of the other people and the like can be identified based on the images of the other people for analysis, whether the other people peep the large screen is judged, and whether a suspected peeping event occurs in the second image is further identified.

The third object in the above steps may be, but is not limited to, a candid camera or a user watching a large screen. The second behavior may be a behavior of performing a candid photograph using a candid photograph tool, but is not limited thereto.

In an optional embodiment, the AI algorithm may be used for identifying, in the second image, an image of the candid camera or a human body motion image, determining whether a person uses the candid camera to candid the second image, and further identifying whether a suspected candid camera event occurs in the second image.

In an alternative embodiment, the image server may receive the thumbnail of the image sent by the S-side and display the thumbnail of the image. After the user sees the thumbnail of the image in the image server, the user can determine the image to be displayed on the large screen through key mouse or touch operation, the control end can generate a display instruction according to the operation action of the user and send the display instruction to the image server, wherein the display instruction comprises an S-terminal identification code to be displayed. After receiving the display instruction from the user, the image server may determine image data of the display image to be displayed on the large screen according to the S-terminal identification code in the display instruction.

It should be noted that, an S-terminal identification code corresponds to an S-terminal, that is, an image source device. Since the image server may be connected to a plurality of S terminals, and one S terminal is connected to one image source device, it is necessary for a user to determine which S terminal acquired image is to be displayed on a large screen through an S terminal identification code carried by a display instruction.

In an optional embodiment, the image server may decode the image data of the display image, divide the display image into sub-images corresponding to the respective screens according to a preset image division manner, encode the sub-images, generate image data of the sub-images, and send the image data of the sub-images to the R terminal connected to the respective screens. And the R end decodes the received coded data and displays the sub-images corresponding to the screens on the connected screens.

A preferred embodiment of the present invention will be described in detail with reference to fig. 3 to 7.

As shown in fig. 3, the large screen includes four screens from screen 1 to screen 4, each screen is connected to the R terminal through a video line HDMI, the video line is shown as a thick line in fig. 3, each R terminal is connected to the image server through a network cable, and the image server is connected to the S terminal through a network cable. The user can set the display mode of the image source device on each screen of the large screen through the image server. Specifically, a display image of one image source device may be displayed by a combination of a plurality of screens.

It should be noted that, according to actual needs, a plurality of S terminals may be set to connect with the image server, the R terminal may be placed locally with the large screen, and the image server may be placed in a machine room in a different place.

The top end of the large screen is provided with a camera 00, and the camera 00 is connected with an image server.

As shown in fig. 4, the processing flow of the large screen display image is as follows:

and step S41, the image server receives the image collected by the terminal S and displays the thumbnail of the image.

In step S42, the image server receives a display instruction from the user, and determines image data of a display image to be displayed on the large screen according to the display instruction.

Step S43, the image server encodes the image data of the display image, divides the display image into sub-images corresponding to each screen according to a preset image division manner, encodes each sub-image, generates image data of the sub-image, and sends the image data of the sub-image to the R terminal connected to each screen.

In step S44, the R-side encodes the received screen data and displays each sub-image on the connected screen.

For example, as shown in fig. 3, R1 connects screen 1, R2 connects screen 2, R3 connects screen 3, and R4 connects screen 4, where R1 corresponds to the sub-image at the top left corner after division, R2 corresponds to the sub-image at the top right corner after division, R3 corresponds to the sub-image at the bottom left corner after division, and R4 corresponds to the sub-image at the bottom right corner after division.

As shown in fig. 5, the processing flow of the peep-proof function is as follows:

and step S51, the camera on the large screen acquires the user image and sends the acquired user image to the image server.

And step S52, the image server side judges whether a suspected peeping event occurs at present according to the user image.

Optionally, if a suspected spy event occurs, step S53 is executed, and if a suspected spy event does not occur, step S51 is executed again.

In step S53, after receiving the image data of the display image sent by the S-side, the image server acquires the position information of the sensitive area from the image data.

Step S54, the image server decodes the image data of the display image, determines the R-side corresponding to the frame image according to the position information of the sensitive region and the preset image segmentation mode, and records the R-side corresponding to the sensitive region as the target R-side.

For example, as shown in fig. 6, the outer frame represents a large screen, 4 boxes represent 4 screens as shown in fig. 3, a circle represents the current frame image, and a solid rectangle represents a sensitive area. It can be determined that the sensitive regions are located in the upper right hand small graph and the lower left hand small graph after segmentation, and the corresponding target R ends are R2 and R3.

In step S55, the image server discards the image data of the thumbnail to be sent to the target R-side, and sends the image data of the preset image to the target R-side.

In step S56, the target R-side decodes the image data of the preset image and displays the decoded image data on the connected screen.

For example, as shown in fig. 7, when it is determined that a plausible peeking event occurs, the target R ends corresponding to the sensitive areas are determined to be R2 and R3, the image server may send image data (black images) of preset images to R2 and R3, and then black images are displayed on the screen 2 connected to R2 and the screen 3 connected to R3, so that the user cannot see the sensitive areas on the large screen.

Through the steps, when a suspected peeping event around the large screen is determined, firstly, according to a preset display mode, determining an R end corresponding to a small image to which a sensitive area belongs after a current frame image is segmented; then, the image data of the current frame which should be originally sent to the R end is discarded, and the preset replacement image is sent to the R end, so that the user cannot see the information of the sensitive area in the large screen, and information leakage can be avoided.
