[0004] In existing technologies, when users view multi-channel outbound monitoring screens or single-channel outbound monitoring screens through the smart central control screen, they need to manually operate the central control screen or interact with the central control screen through voice to perform operations. However, the manual operation scenario experience is cumbersome, the operation path is long, and it is necessary to click on each item to enter, which affects the user experience. Although the voice interaction method does not require manual operation by the user, the operation through voice interaction will be affected by many factors. For example, in a noisy environment, the accuracy of voice recognition will be greatly reduced; and voice interaction depends on the maturity of voice recognition technology. Under existing technology, voice recognition will still misunderstand or misrecognize user instructions. In addition, for users' operations in different scenarios, existing technical solutions need to formulate specific paths or detailed voice instructions for each functional application, which has high operating costs and poor user convenience.

[0044] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

In addition, the terms "first", "second", and "third" in this application are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

[0047] The video image display method provided in this application is applied to a security system. The security system includes a central control screen device and security equipment. The central control screen device can be a smart home control panel or other device with display capabilities, and the security equipment can be a device with video image acquisition capabilities, such as a monitor. The central control screen device and the security equipment are connected, and the central control screen device is used to display multiple video images captured by the security equipment.

[0048] Please refer to Figure 1, which is a flow chart of the first embodiment of the method provided by this application. The method for displaying a video screen provided by this embodiment of the application is used to control the central control screen device to switch and display the video screen, and specifically includes the following steps:

[0049] S1: Pre-set a plurality of gesture commands, wherein each gesture command is bound to a corresponding video screen.

[0050] Among them, the central control screen device is used to display multiple video images obtained by the security equipment. However, due to the limitation of the screen size of the central control screen device and the user's demand for video image clarity, the central control screen device cannot display all video images at the same time. Therefore, the central control screen device is required to switch the video images based on user needs.

[0051] In this embodiment, the central control screen device can be pre-set with multiple gesture commands. This can be done by the user inputting multiple gesture commands into the central control screen device, or by pre-storing multiple gesture commands in the central control screen device. When the central control screen device wants to bind the gesture commands to the video screen, the central control screen device directly extracts the multiple gesture commands from its storage area. The user can then operate the central control screen device, and the central control screen device binds the gesture commands to the corresponding video screen based on the user's needs. For example, the first gesture command can be bound to the first video screen, the second gesture command can be bound to the second video screen, and so on. After the central control screen device binds the gesture commands to the corresponding video screens, step S2 is entered.

[0052] S2: receiving a gesture command input by the user, extracting a video image corresponding to the gesture command, and switching the video image to be displayed on the central control screen device.

[0053] Among them, after the central control screen device receives the gesture command input by the user, since the central control screen device has pre-bound the gesture command with the video screen, the central control screen device can directly extract the corresponding video screen based on the gesture command input by the user, so as to switch and display the video screen on the central control screen device to meet the user's needs.

[0054] For example, when a user wants to watch a first video, they can input a first gesture command. When the central control screen device receives the first gesture command, the central control screen device immediately extracts the first video bound to the first gesture command and displays it on the central control screen device, meeting the user's viewing needs. This improves the central control screen device's response speed to user commands, eliminates the need for user voice or manual operation, simplifies the user's operation of the central control screen device, and improves the user's experience of operating the central control screen device.

[0055] It can be understood that before receiving the user's gesture command, the central control screen device can enter the screen-off mode to save the power consumption of the central control screen device; or the central control screen device can display the default video screen set by the user, wherein the default video screen can be set by the user himself, or the central control screen device defines the video screen that the user has watched the most times as the default video screen. After receiving the user's gesture command and the central control screen device displays the corresponding video screen, the central control screen device can also detect whether the user is still in the viewing area of ​​the central control screen device. If the central control screen device detects that the user is in the viewing area of ​​the central control screen device, that is, the user is still watching the video screen, the central control screen device maintains displaying the corresponding video screen. If the central control screen device detects that the user is not in the viewing area of ​​the central control screen device, then the central control screen device can enter the screen-off mode to save power consumption, or the central control screen device can switch to display the default video screen again. This application does not limit the operating status of the central control screen device in other time periods when the central control screen does not receive gesture commands.

[0056] Please refer to Figure 2, which is a flow chart of the second embodiment of the method provided by this application. In step S1, the specific steps of binding each gesture instruction with the corresponding video image include:

[0057] S21: Binding corresponding video images based on the preset time period and gesture instructions.

[0058] As mentioned above, the central control screen device pre-binds gesture commands with video images. If there are N video images, the central control screen device must pre-set N gesture commands. As the number of gesture commands increases, the complexity of the gesture commands will inevitably increase in order to distinguish each gesture command, which will make it difficult for users to input gesture commands. Alternatively, if there are too many gesture commands, users will need to memorize multiple gesture commands, which will require a certain amount of memory and increase the difficulty of user input.

[0059] Therefore, this embodiment further proposes that the central control screen device can bind the gesture command to the corresponding video screen based on the preset time period. For example, the central control screen device can monitor the time period when the user uses the gesture command to switch the video screen to obtain the preset time period.

[0060] Specifically, if the central control screen device monitors that the time periods when users often use gesture commands to switch video screens are 10:00 am and 5:00 pm every day, then the preset time periods can be 9:30 am to 10:30 am and 4:30 pm to 5:30 pm. In this case, the central control screen device can bind gesture commands to corresponding video screens based on the preset time periods. For example, the central control screen device binds the first gesture command to the first video screen based on the time period from 9:30 am to 10:30 am; and binds the first gesture command to the second video screen based on the time period from 4:30 pm to 5:30 pm. That is, based on different preset time periods, the first gesture command can be bound to different video screens, and then when the central control screen device receives the first gesture command input by the user within different preset time periods, it can extract different video screens for display.

[0061] For example, if the central control screen device receives the first gesture command at 10:00 AM, which falls within the preset time period of 9:30 AM to 10:30 AM, the first video frame will be extracted and displayed. If the central control screen device receives the first gesture command at 5:00 PM, which falls within the preset time period of 4:30 PM to 5:30 PM, the second video frame will be extracted and displayed. This reduces the number of gesture commands set on the central control screen device, reduces the gesture complexity of the gesture commands, and simplifies the difficulty for users to enter gesture commands.

[0062] It is understandable that in other embodiments, the central control screen device may bind the first gesture instruction to the first video screen based on 9:30 a.m. to 10:30 a.m., and bind the second gesture instruction to the second video screen based on 4:30 p.m. to 5:30 p.m.; or the central control screen device may bind the second gesture instruction to the first video screen based on 9:30 a.m. to 10:30 a.m.; and bind the second gesture instruction to the second video screen based on 4:30 p.m. to 5:30 p.m., etc. This application does not limit the number of gesture instructions used by the central control screen device or the specific gesture instructions.

[0063] In another embodiment, the preset time period can also be directly entered into the central control screen device by the user, and this application does not impose any restrictions on this.

[0064] S22: receiving a gesture command input by the user during a preset time period, and switching to display a corresponding video screen.

[0065] Among them, when the central control screen device receives a gesture command input by the user within a preset time period, the central control screen device directly extracts the corresponding video screen for display to meet the user's viewing needs.

[0066] In summary, the central control screen device in this embodiment can bind gesture commands and video images based on a preset time period to reduce the number of gesture commands, reduce the difficulty of users inputting gesture commands, improve human-computer interaction efficiency, and improve the user experience of the video image display method provided in this embodiment.

[0067] In other embodiments, if the number of video images displayed by the central control screen device is small, the central control screen device can directly bind the gesture command with the video image according to step S1 without considering the preset time period.

[0068] In other embodiments, please refer to FIG3 , which is a flowchart of the third embodiment of the method provided by the present application. The central control screen device pre-sets multiple gesture commands, wherein each gesture command is bound to the corresponding video screen in the specific steps further including:

[0069] S31: Acquire multiple preset time periods within a preset cycle, and in response to receiving the same gesture instruction input by the user to extract the corresponding video screen a number of times greater than or equal to a preset number within the multiple preset time periods within the preset cycle, bind the preset time period and the gesture instruction.

[0070] Among them, the time difference between any adjacent preset time periods of multiple preset time periods within the preset cycle is equal. For example, the preset cycle is one week, and the preset time period is from 9:00 a.m. to 10:00 a.m. every day, then any adjacent preset time periods are from 9:00 a.m. to 10:00 a.m. of the previous day, and from 9:00 a.m. to 10:00 a.m. of the next day. That is, multiple preset time periods are the same time period every day within the preset cycle, for example, from 9:00 a.m. to 10:00 a.m. every day.

[0071] If the user inputs the same gesture command into the central control screen device a number of times greater than or equal to a preset number within multiple preset time periods within a preset cycle, the central control screen device automatically binds the gesture command to the preset time period. The preset cycle can be one week, and the preset time period can be a fixed time each day, such as 10:30 to 11:30 p.m. every night. When the preset cycle is one week, the preset number of times can be five or more. It should be understood that the above preset cycles, preset time periods, and preset number of times are examples only and can be set by the user.

[0072] In one embodiment, when the user inputs a first gesture command to the central control screen device between 10:30 and 11:30 p.m. every day for seven consecutive days in a week to make the central control screen display the first video screen (at this time, the number of times is seven times, the preset number of times is five times, and the user inputs the same gesture command to the central control screen device more times than the preset number of times within multiple preset time periods of the preset cycle), the central control screen device automatically binds 10:30 to 11:30 p.m. (preset time period) with the first gesture command.

[0073] Specifically, if the central control screen device receives a gesture instruction to extract the corresponding video image within one of multiple preset time periods of a preset cycle, the count is incremented by one. If the central control screen device receives a first gesture instruction to extract the first video image within a preset time period, the count is incremented by one. In other embodiments, if the user uses the first gesture instruction to extract the first video image more than once within the same preset time period, the central control screen device only records the number of times the first gesture instruction was used to extract the first video image once. That is, if a recorded gesture instruction and its corresponding video image appear within a preset time period, no matter how many times the gesture instruction appears, it is only recorded once.

[0074] In summary, the central control screen device can automatically bind the gesture commands that users use frequently with the preset time periods when users use the gesture commands frequently, further improving the response efficiency of the central control screen device to the gesture commands input by users and realizing the intelligence of the central control screen device.

[0075] S32: receiving a gesture command input by the user, and directly displaying a corresponding video screen.

[0076] After binding the preset time period with the gesture command in step S31, the central control screen device will directly display the corresponding video screen if it receives the gesture command within the next preset time period. That is, after binding the preset time period with the gesture command, in the same specific time period every day, the user can use simple gesture commands to extract the video screen he wants to watch, thereby improving the response efficiency to the gesture commands input by the user.

[0077] In one embodiment, please refer to FIG4 , which is a flow chart of a fourth embodiment of the method provided by the present application. The specific steps of the method provided by the embodiment of the present application also include:

[0078] S41: Bind the video recording devices in multiple monitoring areas to the central control screen device, and obtain video images through the video recording devices.

[0079] The central control screen is used to display multiple video images captured by security equipment, which may include multiple recording devices. The recording devices are used to capture video images of corresponding monitoring areas. The multiple video images can be captured by recording devices in multiple monitoring areas. For example, the first recording device in the courtyard is used to capture the first video image, the second recording device in the living room is used to capture the second video image, and the third recording device in the room is used to capture the third video image. The central control screen can be pre-bound to the recording devices in multiple monitoring areas, and then capture device images through each recording device. For example, when a user inputs a gesture command to the central control screen to display the video image in the courtyard, the central control screen immediately switches to display the first video image captured by the first recording device. The recording device can be a surveillance camera, etc.

[0080] In one embodiment, a user can pre-register the recording devices for multiple monitoring areas into their personal account via a dedicated mobile phone app, then log in to the central control screen device with their personal account. The central control screen device then reads the recording device information for multiple monitoring areas under the user's personal account, thereby binding the central control screen device to the recording devices for multiple monitoring areas. Alternatively, the user can directly register the recording devices for multiple monitoring areas into the central control screen device, which then binds the registered recording devices. This application does not limit the specific binding method between the central control screen device and the recording devices.

[0081] S42: The central control screen device displays the video image obtained by the video recording device.

[0082] Furthermore, in step S41, after the central control screen device is bound to the recording device, the central control screen device can obtain the video images of each monitoring area through the recording device, and then after the user inputs a gesture command, the central control screen device can display the video images of the corresponding monitoring area.

[0083] Further, please refer to Figure 5, which is a flowchart of the first embodiment of step S42 in Figure 4. The specific steps of displaying the video screen on the central control screen device in step S42 include:

[0084] S51: Divide the display area of ​​the central control screen device into multiple sub-display areas.

[0085] As mentioned above, the central control screen device binds the recording devices of multiple monitoring areas. Therefore, the central control screen device can divide its display area into multiple sub-display areas. In one embodiment, if the multiple monitoring areas include the entrance, courtyard, living room, and baby room, the central control screen device can divide its display area into four sub-display areas, such as a four-square grid, to simultaneously display the video images of each monitoring area. The specific division method and the size of each sub-display area can be customized by the user.

[0086] S52: The video recording device in each monitoring area is matched with each sub-display area one by one and bound.

[0087] Among them, after the central control screen device divides its own display area, the central control screen device can correspond and bind the recording device of each monitoring area to each sub-display area one by one, as shown in Figure 6, which is a structural diagram of the first embodiment of the display area of ​​the central control screen device of the present application. Among them, the first sub-display area 61 can be bound to the recording device of the courtyard to display the first video picture of the courtyard; the second sub-display area 62 can be bound to the recording device at the door to display the second video picture of the door. The third sub-display area 63 can be bound to the recording device in the living room to display the third video picture of the living room. The fourth sub-display area 64 can be bound to the recording device in the baby room to display the fourth video picture of the baby room. Each sub-display area displays the video picture obtained by the recording device of the corresponding monitoring area.

[0088] Furthermore, after the central control screen device receives a gesture command input by the user, the central control screen device can obtain the corresponding video image and display it in full screen. For example, if the user wants to watch the video image of the baby room, they input the corresponding gesture command, and the central control screen device extracts the fourth video image in the fourth sub-display area and displays it in full screen for the user to watch clearly.

[0089] In other embodiments, please refer to FIG7 , which is a flowchart of a fifth embodiment of the method provided by the present application. The sub-display area displays the video images captured by the recording device of the corresponding monitoring area, and further comprises the following specific steps:

[0090] S71: In response to the existence of at least one recording device in the monitoring area, all the recording devices in the monitoring area are bound to the corresponding sub-display area.

[0091] In actual applications, using a single recording device for a monitoring area may not be enough to fully monitor the area. Therefore, users often need to equip each monitoring area with at least one recording device. For example, if the courtyard is very large, four recording devices may be needed to monitor the courtyard to ensure that the recording devices can fully monitor the courtyard. When the central control screen device responds to the presence of at least one recording device in the monitoring area, the central control screen device binds all recording devices in the monitoring area to the corresponding sub-display area, and binds the four recording devices in the courtyard to the first sub-display area 61, so that the video images captured by the four recording devices in the courtyard can be displayed in the first sub-display area 61.

[0092] S72: The sub-display area displays the video images captured by at least one video recording device in the corresponding monitoring area.

[0093] Among them, since the sub-display area is bound to all the recording devices of the corresponding monitoring area, the video images captured by the recording devices of the monitoring area can be displayed in the corresponding sub-display area. In one embodiment, the central control screen device can pre-set one of the at least one recording devices in the monitoring area as the default recording device, and the video images captured by the default recording device are the video images of the monitoring area that the user most frequently watches. Then the central control screen device controls the sub-display area to display the video images captured by the default recording device, and after receiving the user's gesture command, switches to display the video images captured by other recording devices in the monitoring area on the sub-display area. For example, the courtyard includes a first recording device and a second recording device, and the first recording device is the default recording device. The central control screen device controls the first sub-display area 61 to display the video images captured by the first recording device, and after receiving the user's gesture command, switches to display the video images captured by the second recording device in the first sub-display area 61.

[0094] In another embodiment, the central control screen device may further divide the corresponding sub-display area in advance so that the video images captured by all recording devices in the monitored area can be displayed in the sub-display area. Upon receiving a user gesture command, the corresponding video images in the monitored area are controlled to be displayed full-screen in the sub-display area. For example, if a courtyard includes a first recording device and a second recording device, the central control screen device may divide the first sub-display area 61 into two, for simultaneously displaying the video images captured by the first recording device and the video images captured by the second recording device. Upon receiving a user gesture command, the video images captured by the first recording device are controlled to be displayed full-screen in the first sub-display area 61 for clear viewing by the user.

[0095] It can be understood that when the central control screen device divides the display area into multiple sub-display areas, the operation of switching the video screen is performed by receiving the user's gesture command in step S72, which is to switch the video screen in the sub-display area corresponding to the corresponding monitoring area, while the video screens in other sub-display areas are not affected and continue to be displayed, thereby improving the user's viewing experience of the video screen.

[0096] Alternatively, please refer to Figure 8, which is a flow chart of a sixth embodiment of the method provided by this application. The method provided by this embodiment of the application further includes the following steps:

[0097] S81: In response to a preset event occurring in a video image captured by a first video recording device in a monitored area, other video recording devices bound to the first video recording device are acquired.

[0098] The preset events that appear in the video can be preset people, objects, or behaviors, for example, a package box thrown into a courtyard. The central control screen device can pre-acquire the preset events set by the user so that it can promptly identify and respond to the preset events when they appear in the video.

[0099] In one embodiment, the first recording device can be bound to other recording devices in the monitoring area where the first recording device is located, and then the central control screen device responds to a preset event in the video screen obtained by the first recording device, and the central control screen device obtains other recording devices in the monitoring area, and displays all the video screens obtained by the first recording device and other recording devices bound to it in the corresponding sub-display area, or displays them in full screen in the display area of ​​the central control screen device. Since the preset event occurs in the video screen, the central control screen device can increase the priority of the video screen and other video screens bound to it, and switch the video screens of other sub-display areas to display video screens with higher priorities, thereby improving the intelligence level of the central control screen device in displaying video screens.

[0100] Among all the video frames captured by the first recording device and its bound recording devices, two of them have overlapping areas. That is, the video frames captured by at least two recording devices in the monitoring area have overlapping areas, and thus all the recording devices in the monitoring area can monitor the entire area of ​​the monitoring area.

[0101] In other embodiments, the first recording device may be bound based on a user-preset behavior path. For example, when a preset person appears walking in the first recording device in the courtyard, the preset person is judged to appear in the second and third recording devices according to the preset route of the preset person's walking. The second and third recording devices may not belong to the same monitoring area as the first recording device. For example, when the preset person appears in the first recording device in the courtyard, the user's preset behavior path is that the preset person will appear in the living room after leaving the courtyard. In this case, the central control screen device binds the first recording device in the courtyard and the second recording device in the living room, and when the preset person appears on the video screen of the first recording device, the video screen of the second and third recording devices are extracted and displayed on the central control screen device, so that the user can clearly track the preset person.

[0102] Among them, after the central control screen device extracts the video images obtained by the first recording device, the second recording device and the third recording device, it can display the video images obtained by the corresponding recording device in the sub-display area corresponding to each recording device, or display the video images in full screen, etc. This application does not impose any restrictions on this.

[0103] S82: Detect whether the user is in the viewing area of ​​the central control screen device.

[0104] After the central control screen device responds to a preset event in response to the video image captured by the first recording device, the central control screen device can further detect whether the user is in the viewing area of ​​the central control screen device. As mentioned above, when no gesture command from the user is received, the central control screen device can be in the screen-off state. Therefore, the central control screen device needs to detect whether the user is in the viewing area of ​​the central control screen, and then determine whether the central control screen device should display the video image captured by the first recording device and other devices bound to the recording device, to avoid displaying the video image when the user is not in the viewing area, which would cause energy consumption.

[0105] It is understood that the central control screen device is equipped with a sensor device such as a proximity sensor, and the proximity sensor of the central control screen device can sense whether a user is within the viewing area of ​​the central control screen device. For example, the proximity sensor can detect whether a user is within the area where the central control screen device is located. If so, it is determined that the user is within the viewing area of ​​the central control screen device; if not, it is determined that the user is not within the viewing area of ​​the central control screen device. The user inputting gesture commands to the central control screen device as described above can also be completed with the assistance of the sensors of the central control screen device.

[0106] When the central control screen device detects that the user is in the viewing area of ​​the central control screen device, step S83 is entered.

[0107] When the central control screen device detects that the user is not in the viewing area of ​​the central control screen device, step S84 is entered.

[0108] S83: Simultaneously display all video images acquired by the first video recording device and other video recording devices bound thereto.

[0109] When the central control screen device detects that the user is in the viewing area of ​​the central control screen device, the central control screen device can directly display all video images obtained by the first recording device and other bound recording devices for the user to watch.

[0110] S84: Generate a warning message and send it to the mobile device bound to the central control screen device.

[0111] When the central control screen device detects that the user is not in the viewing area of ​​the central control screen device, that is, if the central control screen device displays the video image at this time, the user will not be able to watch the video image, and the central control screen device will waste energy by displaying the video image. Therefore, in this case, the central control screen device may not display the video image, but instead generate an early warning message indicating that a preset event has occurred in the video image, and send the early warning message to the mobile device bound to the central control screen device, such as the dedicated mobile phone app mentioned above, to remind the user that the preset event has occurred in the video image.

[0112] Then, the user may move to the viewing area of ​​the central control screen device after receiving the warning information. After the central control screen device detects that the user is in the viewing area of ​​the central control screen device, the central control screen device displays the video image for the user to watch.

[0113] In summary, this application uses innovative interaction methods to realize the operation of the central control screen device through gesture commands, improving the efficiency and experience of human-computer interaction. Users no longer need to use complex operations / voice commands to switch the functional applications of the central control screen device. A simple gesture command can achieve the purpose, improving the convenience of users operating the central control screen device.

[0114] The present application also provides a security system (not shown), wherein the security system includes a central control screen device and a security device, the security device is connected to the central control screen device, the security device is used to obtain video images, and the central control screen device is used to execute the method described above to display the video images obtained by the security device.

[0115] Among them, the central control screen device also includes a sensor, which is used to obtain the user's gesture commands. The central control screen device switches to display the corresponding video screen based on the gesture commands, thereby improving the efficiency and experience of the user's interaction with the central control screen device.
