[0031] Example 1

[0032] The method embodiment provided in the first embodiment of the present application can be executed in a home central control screen, display screen, device display panel, controller or similar device management device. Taking running on a home central control screen as an example, Figure 1 1 is a hardware structure diagram of a home central control screen according to an embodiment of the present invention. Figure 1 As shown, the home control screen may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. Optionally, the above-mentioned home control screen may also include a transmission device 106 for communication functions and an input and output device 108. It can be understood by those skilled in the art that Figure 1The structure shown is only for illustration and does not limit the structure of the above-mentioned home central control screen. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0033] The memory 104 can be used to store a home control screen program, for example, a software program and module of an application software, such as a home control screen program corresponding to a method for controlling the screen of a device in an embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the home control screen program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0034] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the home control screen. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0035] In this embodiment, a method for controlling the screen lighting of a device is provided. Figure 2 is a flow chart of a method for controlling a bright screen of a device according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0036] Step S202, controlling the display screen to enter a screen-off state, and monitoring a living body signal through an infrared sensor, wherein the display screen includes the infrared sensor, a camera, and a fill light;

[0037] Step S204, if a living body signal is detected, activating the camera and the fill light;

[0038] Optionally, the living body signal may be a signal of a human body. The camera may be an infrared camera.

[0039] Step S206, obtaining a face image captured by the camera;

[0040] A face image is an image containing a human face area.

[0041] Step S208: lighting up the display screen according to the face image.

[0042] Through the above steps, the display screen is controlled to enter the screen-off state, and the infrared sensor is used to monitor the living signal, wherein the display screen includes the infrared sensor, the camera and the fill light; if the living signal is detected, the camera and the fill light are activated; the face image captured by the camera is obtained; the display screen is lit according to the face image, and when the display screen is in the screen-off state, the display screen is controlled to be lit according to the captured face image, thereby avoiding the display screen from being lit when no one is around, solving the technical problem of energy waste and light pollution caused by the display screen being always on in the related technology, reducing power consumption, and extending the life of the device's display screen.

[0043] Figure 3 : is a schematic diagram of the structure of a display device of an embodiment of the present invention, and the display device includes: an infrared sensor, an infrared camera, an infrared fill light, a microcontroller unit (MCU), a light sensor, and a central control screen. Infrared sensor: used to monitor whether there is a human body's thermal signal in the environment, with high sensitivity and a wide detection range, and can effectively identify even tiny human body thermal radiation, thereby achieving accurate human body detection. This allows the system to operate reliably in a variety of environments. The infrared camera captures high-quality images in low-light environments, and the built-in algorithm supports fast face detection and recognition functions. Even in a completely dark environment, the camera can provide clear images through infrared technology, providing sufficient data support for subsequent image processing. Infrared fill light: When the presence of a user is detected, the system automatically activates the infrared fill light to enhance the ambient light, ensuring that the camera obtains the best image quality under low-light conditions, thereby improving the success rate of face recognition. The brightness of the fill light can be automatically adjusted according to the ambient light to ensure that the user experience is not affected. Central control screen: It integrates advanced face recognition algorithms and control logic with the MCU to analyze and process the captured images. The central control screen is not only used to display information, but also provides comprehensive home control functions through linkage with other smart devices. Light sensor: The photoresistor is connected to the analog input of the microcontroller to form a resistor divider circuit to obtain the analog value of light intensity. The design of this part is crucial. It can monitor the ambient brightness in real time and determine whether the current light intensity is in a dark environment, thereby providing basic data for subsequent operations.

[0044] In this embodiment, controlling the display screen to enter the screen-off state includes: obtaining the light intensity value of the environment where the display screen is located; determining whether the light intensity value is less than a preset intensity; if the light intensity value is less than the preset intensity, controlling the display screen to enter the screen-off state.

[0045] Optionally, the light intensity value of the environment where the display screen is located is collected in real time through a light sensor, which includes a photoresistor. The photoresistor is connected to the analog input terminal of the microcontroller, and the analog value of the light intensity (light intensity value) is obtained through a resistor divider circuit. If it is judged that the current light intensity is less than the preset intensity, it belongs to a dark environment. If the light intensity is higher than the preset intensity, the screen remains on and the light intensity is continuously detected.

[0046] By adopting the solution of this embodiment, when the light intensity value of the environment where the display screen is located is low, the display screen is controlled to enter the screen-off state, thereby saving the power consumption of the display screen and extending the service life of the display panel.

[0047] In one implementation of the present embodiment, lighting up the display screen according to the facial image includes: determining a first facial image captured by the camera at a first time and a second facial image captured at a second time, wherein the first time is later than the second time; identifying a movement trend of a target face relative to the front of the display screen according to the first facial image and the second facial image; and lighting up the display screen if the target face is approaching the front of the display screen.

[0048] Optionally, the moving trend includes an approaching trend, a moving away trend, and a staying trend. If it is an approaching trend, the display screen is lit up; if it is a moving away trend, the screen is kept off; if it is a staying trend, the current state is maintained (which can be a lighted screen state or a screen off state).

[0049] The solution of this embodiment is to obtain facial images collected at multiple times and determine the user's movement trend relative to the display screen. By screening scenes where there are living things but the screen does not need to be lit, the number of unnecessary times the display screen is lit is reduced, thereby saving the power consumption of the display screen.

[0050] In one example, identifying the movement trend of a target face relative to the front of the display screen based on the first face image and the second face image includes: intercepting a first face area in the first face image, and intercepting a second face area in the second face image, wherein the first face image and the second face image have the same size; comparing the sizes of the first face area and the second face area; if the size of the first face area is larger than the size of the second face area, determining that the target face is approaching the front of the display screen; if the size of the first face area is smaller than the size of the second face area, determining that the target face is moving away from the front of the display screen.

[0051] In one example, before comparing the sizes of the first face area and the second face area, the method further includes: calculating the proportion of the first face area in the first face image; determining whether the proportion is greater than a preset proportion (such as 20%); if the proportion is greater than the preset proportion, determining to compare the sizes of the first face area and the second face area, and if the proportion is less than or equal to the preset proportion, maintaining the screen off state and continuing to capture the third face image. By calculating the proportion of the face area in the face image, the judgment of the user's movement trend is continued only when the proportion is large, which can avoid lighting the screen when the living body is too far away from the display screen, and can also ensure the recognition accuracy of the face area (such as size, eye direction, etc.).

[0052] By adopting the solution of this embodiment, the user's movement trend is determined by the size change of the face area in the entire face image, which improves the accuracy of the movement trend and further improves the accuracy of controlling the display screen to light up.

[0053] In one implementation of this embodiment, lighting up the display screen according to the facial image includes: calling a preset facial library to perform facial recognition on the facial image; if the facial recognition passes, lighting up the display screen.

[0054] If the face in the face image matches any entered face in the preset face library, the face recognition is considered to have passed, otherwise, the face recognition has failed.

[0055] Optionally, if the face recognition fails, the display screen remains off, and the camera is controlled to enter infrared recording mode, and an alarm message is sent to a preset account (such as the owner of the display screen, a registered user, etc.) to indicate that a stranger has invaded the room.

[0056] By adopting the solution of this embodiment, when the collected facial image passes the face recognition, the display screen is lit up. On the one hand, the user privacy is protected. On the other hand, the security monitoring of the room is realized based on the display screen, and the utilization rate of the display screen is improved.

[0057] In one implementation of the present embodiment, lighting up the display screen according to the facial image includes: identifying the attention direction of a target living body according to the facial image, wherein the target living body is a living body appearing in the facial image; determining whether the attention direction intersects with the plane area where the display screen is located; if the attention direction intersects with the plane area where the display screen is located, lighting up the display screen based on a first brightness; if the attention direction does not intersect with the plane area where the display screen is located, lighting up the display screen based on a second brightness, wherein the second brightness is lower than the first brightness.

[0058] In addition to identifying the target living body's attention direction based on the facial image, the target living body's attention direction can also be identified by acquiring the ambient audio collected by the display screen, detecting the on state of home appliances connected to the display screen (the display screen is a control screen for controlling home appliances), etc. For example, if the TV is on, or the sound component of the target living body is detected in the ambient audio, the target living body's attention direction may be on the TV, or there may be no fixed attention direction.

[0059] Optionally, the first brightness is working brightness, and the second brightness is standby brightness.

[0060] If the attention direction intersects with the plane area where the display screen is located, it means that the target living being is looking at the display screen, and the display screen can be lit up to facilitate user operation. If the attention direction does not intersect with the plane area where the display screen is located, it means that the probability of the target living being displaying and operating the display screen is small, but the display screen is lit up based on the second brightness so that the attached target living being can operate in time, while saving power consumption of the display screen.

[0061] By adopting the solution of this embodiment, the brightness of the display screen is controlled by the attention direction of the target living body. When the user is looking at the display screen, the display screen is lit normally. When the user is not looking at the display screen, the display screen is lit at low brightness, thereby improving the screen lighting flexibility of the display screen.

[0062] In one example, identifying the attention direction of a target living body based on the facial image includes: capturing a body area and an eye area in the facial image; determining a frontal orientation of the body area as a first direction, and determining a second direction based on an eyeball orientation of the eye area; and determining an intermediate direction between the first direction and the second direction as the attention direction of the target living body.

[0063] In this example, when calculating the first direction and the second direction, a two-dimensional or three-dimensional coordinate system can be constructed, and the coordinates are constructed with the center point of the display screen as the origin. The normal of the plane where the body area is located is calculated as the first vector, and the ray in the direction of the eyeball is calculated as the second vector. The angular components of the first vector and the second vector are respectively determined as the angles of the first direction and the second direction in the coordinate system, and the intermediate vector of the first vector and the second vector is calculated, and the direction of the intermediate vector is determined as the attention direction of the target living body.

[0064] By adopting the solution of this embodiment, the frontal orientation of the body area and the eye orientation of the eye area are used to calculate the attention direction of the target living body, while considering the user's body and eye directions, thereby improving the accuracy of the attention direction.

[0065] The solution of this embodiment realizes the efficient cooperation between the infrared sensor and the camera. The infrared sensor is used to detect the human body, and the camera and infrared fill light are used for face detection and recognition under low light conditions. Through face recognition, strangers are screened out to protect privacy. The face area method is used to identify whether the face is approaching or far away, and the scenes that need to light up the screen are screened out. The screen can be automatically turned on when the user is detected and needed, and turned off otherwise. The design of this system not only optimizes energy utilization efficiency, but also improves the user's interactive experience. It is suitable for a variety of smart home scenarios, such as smart lighting, environmental control, etc.

[0066] Figure 4 This is a screen lighting flow chart of an embodiment of the present invention. The working process of the system is as follows:

[0067] S1: First, connect the photoresistor to the analog input of the microcontroller and obtain the analog value of the light intensity through the resistor voltage divider circuit. If the current light intensity is judged to be a dark environment, the system will enter the next step S2; if the light intensity is higher than the set threshold, it will continue in this step and loop to detect the light intensity.

[0068] S2: After entering S2, the system starts the PIR sensor to detect whether there is a human signal. At this time, the system sets a time window, such as 2 seconds. If no human signal is detected within this time, the system returns to S1; if a signal is detected, it enters the next step S3.

[0069] S3: After confirming the presence of a person, the system activates the infrared camera and fill light to capture a clear image. The fill light provides the necessary lighting at this stage to ensure that the camera can obtain high-quality image data, thereby improving the accuracy of recognition, and then enters S4.

[0070] S4: The system passes the captured image to the microcontroller (MCU) and uses its built-in image processing module to perform face detection. This step lasts for 2 seconds. If no face is detected during this period, it returns to S1; if the face is successfully detected, the system will enter the next step S5.

[0071] S5: Finally, the MCU lights up the home control screen through control signals, providing a visible interface for users to perform subsequent operations and interactions. This process not only improves the intelligence level of the device, but also significantly improves the user experience, ensuring that information and services are provided at the right time.

[0072] In this embodiment, family members' faces are pre-recorded, and the input face information is detected and compared. If it is a stranger, the process jumps to step S1, otherwise, the process jumps to step S3.

[0073] Using the face recognition algorithm, calculate the area S1 of the current face in the picture. After 1 second, detect and calculate the area S2 of the face in the picture again. Compare S1 and S2. If S2>S1, it means that the face is approaching and there is a need to brighten the screen. Otherwise, it is considered that the face is moving away and there is no need to brighten the screen.

[0074] In this embodiment, by combining the camera with the infrared sensor, the system can accurately recognize the user's face in low light conditions, thereby realizing intelligent control of the screen on and off. This technology not only significantly reduces power consumption and extends the service life of the device, but also improves the convenience and comfort of users when using smart home products, ensuring that the device automatically saves energy when not in use. In addition, considering the application of face recognition and scene recognition, user privacy is protected and intelligence is improved.
