[0056] Reference Figure 1-Figure 7 , this embodiment provides a baby monitor with power saving mode and dim light full color, including a camera unit 1, and a monitoring display unit 2 connected to the camera unit 1;

[0057] The monitoring display unit 2 includes a display back-end load, a display communication module and a first power controller 21, wherein the display back-end load is connected to the display communication module and the first power controller 21 respectively, and the display communication module is connected to the first power controller 21, and enters the sleep mode through the display communication module and / or the first power controller 21 controls the on / off of the display back-end load power supply circuit;

[0059] In the above embodiment, the baby monitor with power saving mode and dim light full color includes a camera unit 1 and a monitoring display unit 2 connected to the camera unit 1, wherein the application scenarios of the monitor include but are not limited to infants, the elderly, other special groups (patient groups, disabled people, cognitively impaired people) or pets, and the monitoring display unit 2 includes a display back-end load, a display communication module and a first power controller 21, and the display back-end load is respectively connected to the display communication module and the first power controller 21, wherein the display communication module preferably adopts an FHSS network, i.e., a frequency hopping spread spectrum (Frequency-Hopping Spread Spectrum). Spectrum) network, the display communication module has management and communication functions, it is connected to the first power controller 21, during the operation of the entire baby monitor with power saving mode and dim full-color, it can enter the sleep mode according to the system requirements to reduce power consumption, the first power controller 21 is mainly responsible for controlling the on-off of the rear-end load power supply circuit, the rear-end load may include a display screen, related circuit modules, etc., by controlling the on-off of the power supply circuit, when some functional modules are not needed to work, the power supply can be cut off in time to avoid unnecessary power consumption, the camera unit 1 includes a camera communication module and a camera rear-end load, wherein the camera communication module preferably adopts an FHSS network, i.e., a frequency hopping spread spectrum (Frequency-Hopping SpreadSpectrum) network, the camera communication module is an important component of the camera unit 1, which is used to realize data management and communication functions. It may include some control chips and related circuits. On the one hand, it is connected to the camera back-end load to receive image data collected by the camera, and on the other hand, it interacts and manages data with other related components. The camera back-end load can collect color images in low-light environments, and can be an ordinary camera device that switches between black and white and color according to the judgment of the ambient light brightness. It can also still present color images when the ambient visible light is very weak. That is, the camera unit 1 preferably collects and forms color images. When color images are not needed, black and white images can also be collected. When the camera is an ordinary camera, a setting for judging the ambient light brightness will be set to let the camera work in color Still in the parameters of the black and white image mode (that is, often said to enter the night vision black and white mode, exit the night vision and enter the color mode), the ambient light brightness parameters can be provided by the first illumination sensor 119 or the first image acquisition sensor 122. The acquisition environment of the camera back-end load requires weak visible light to present a color image. When the ambient light is lower than that of the color video, the night light module can be used to supplement the visible light to the environment, or other external visible light supplementary lighting equipment can be used to supplement the light to ensure that the ambient light can meet the requirements of presenting color video. It uses advanced optical sensors and image processing technology to capture the color information of objects in dim light but still with weak light. The collected image data is transmitted to the monitoring display unit 2 through the camera communication module. In the entire baby monitor with power saving mode and low-light full-color,The camera unit 1 and the monitoring display unit 2 are connected through corresponding communication modules to realize the transmission of image data. At the same time, the monitoring display unit 2 can be applied not only to full color but also to common black and white display. The image information collected by the camera back-end load can be accurately transmitted to the monitoring display unit 2 for display.

[0060] The application of the camera back-end load has significantly improved the image acquisition capability of the baby monitor with power saving mode and low-light full-color in low-light environment. Color images can be clearly acquired in indoor environments at night, dark corridors or outdoor scenes before dawn. For scenes that need to be monitored in low-light environments, such as monitoring of the baby room at night, the baby's condition can be more accurately observed, including the color of the baby's clothes, the color information of surrounding objects, etc., providing users with more realistic and detailed monitoring pictures. Compared with traditional cameras that can only acquire black and white images in low-light environments, the camera back-end load can better restore the color information of the monitored scene, which helps users to more quickly and accurately identify the characteristics and status of the monitored objects. For example, when monitoring pets, the changes in the pet's fur color can be seen more clearly, and whether the pet has any abnormal conditions can be discovered in time; the sleep mode function of the display communication module in the monitoring display unit 2 controls the on-off control of the display back-end load power supply circuit, and through the first power controller 21 controls the on-off of the display back-end load power supply circuit, effectively reducing the overall power consumption of the baby monitor with power saving mode and dim light full color. During the time period when real-time image display is not required, such as when most people rest at night, the display communication module enters the sleep mode. At this time, some circuit components inside it stop working or enter a low power consumption state, which greatly reduces the consumption of electricity. At the same time, the first power controller 21 can also cut off the power supply of the back-end load according to actual conditions. For example, when the display screen does not need to work, its power supply circuit is disconnected in time to avoid continuous power consumption of the screen. For a battery-powered baby monitor with power saving mode and dim light full color, it can significantly extend the battery life and reduce the number of charging times, thereby improving the convenience and economy of the baby monitor with power saving mode and dim light full color. At the same time, for users who use baby monitors with power saving mode and dim light full color for a long time, such as families who need to provide long-term care for the elderly or children, it can reduce the cost of use and is also more energy-saving and environmentally friendly.

The second audio signal processing module 427 is a key part for processing audio signals. It obtains power from the third power manager 409 of the second power management component 22, bidirectionally connects to the third communication module 405 for transmitting audio data, and simultaneously connects to the third microphone 407 and the third speaker 406. It can process the sound collected by the third microphone 407 to make it suitable for transmission and The third microphone 407 is used to collect sound signals from the surrounding environment, convert the sound into electrical signals and transmit them to the second audio signal processing module 427; the third speaker 406 receives the audio signal processed by the second audio signal processing module 427, and converts it into sound for playback. The third display load component is the first sound pressure indicator light 417; the first sound pressure indicator light 417 is used to display relevant information of the sound, such as the intensity of the sound, etc. It is connected to the GPIO interface of the third communication module 405, and controls its on and off or flashing frequency by receiving relevant signals.

[0087] The third power manager 409 is used as a core power supply component, which is connected to the second display load component 24 and the third display load component respectively. In the second display load component 24, the second audio signal processing module 427 is bidirectionally connected to the third communication module 405 to form an audio data transmission channel.

In addition, the monitoring display unit 2 also includes a fourth button 421, a fifth button 416 and an eighth button 408, wherein the fourth button 421 The fifth button 416 and the eighth button 408 are respectively connected to the GPIO interface of the third management module 401 and the GPIO interface of the third communication module 405, so as to be used by the user to operate and control the relevant functions. In addition, the second display load component 24 and the third display load component are connected in parallel to the third communication module 405, so that the third communication module 405, the second display load component 24 and the third display load component are powered by the third power manager 409.

[0088] The video display processing circuit is completed by the third management module 401 and the first display screen 422, and their power supply is controlled by the first power controller 21. The processing of the audio signal is completed by the third communication module 405 and the second audio signal processing module 427; first, in the mode where the audio and video work simultaneously, that is, all circuit modules are in power supply operation (this working mode is called "standard mode", and the working mode here can be defined as any name), second, when the user does not watch the video but wants to monitor the sound in real time (this working mode is called "audio monitoring mode", and the working mode here can be defined as any name), third, when the user does not watch the video and does not monitor the sound, the third communication module 405 enters the sleep mode and disconnects the power supply of the rear-end load through the first power controller 21 to reduce power consumption (this working mode is called "ECO mode", and the working mode here can be defined as any name);

[0089] When the monitor display device is set to the power saving mode of "audio monitoring mode", it can always monitor the sound from the camera device end and send audio to the camera device end, and can switch to turn on and off the video display through the fifth button 416. When the video display is turned off, the GPIO of the third communication module 405 will output a signal to control the first power controller 21 to disconnect the power supply to the back-end load third management module 401, memory and LCD display to achieve the purpose of power saving. Within a preset time, if no button of the monitor display device is operated and / or no trigger wake-up signal is received from the camera device end, the GPIO of the third communication module 405 will output a signal to control the first power controller 21 to disconnect the power supply to the back-end load and turn off the video, leaving only the audio function, so it is called "audio monitoring power saving mode".

[0090] When the monitor display device is set to the ultra-power saving mode of "ECO mode", the fifth button 416 can be used to switch on and off the audio and video functions. When the audio and video functions are turned off, the GPIO of the third communication module 405 will output a signal to control the first power controller 21 to disconnect the power supply to the back-end load third management module 401, the memory and the LCD display, and then the third communication module 405 will enter the sleep mode; after the third communication module 405 enters the sleep mode, the user can wake up the third communication module 405 at any time by operating the fifth button 416. After waking up, all circuits will resume power supply and enter the working state, and complete the display or transmission of audio, video and data; in addition, if the third communication module 405 receives a trigger signal to wake up the monitor display device from the same frequency hopping spread spectrum network camera device (the wake-up signal here includes but is not limited to audio data, ambient temperature, ambient illumination, ambient humidity, heart rate, blood oxygen, respiratory rate, body temperature, snoring, moving, flipping, falling, sleeping position, standing position, sitting position, switch state), the third communication module 405 will also wake up and put all circuits into the working state, and complete the display or transmission of audio, video and data.

[0091] Therefore, this embodiment is based on the needs of users who sometimes do not need to view video but only need audio functions (we call it "audio with power saving mode and dim full-color"), and sometimes users do not need to view video and sound functions (we call it "ECO mode"), and controls the first power controller 21 and the third communication module 405 to enter the sleep mode through the third communication module 405 to reduce the overall power consumption to achieve the purpose of ultra-power saving.

The first sound pressure indicator light 417 can be displayed according to the sound-related information through the connection with the third communication module 405, which allows the user to intuitively understand the intensity of the sound and other conditions, providing more information dimensions for monitoring. The fourth button 421 is connected to the GPIO interface of the third management module 401, and the fifth button 416 and the eighth button 408 are connected to the GPIO interface of the third communication module 405, which is convenient for the user to operate the relevant functions.

It is interconnected with the fourth power manager 509 and the fourth battery 512, and can control the charging rate and method according to the battery status and requirements to ensure safe and efficient charging of the battery; the fourth battery 512 serves as a backup power supply for the monitoring and display unit 2. When there is no power supply from the external power adapter 125, it provides electrical energy for the entire unit. It, the fourth charging manager 511 and the fourth power manager 509 form a complete charging and power supply circuit. The fourth display load component 27 includes a fourth memory 529 and a second display screen 522. The fourth memory 529 is used to store data related to the monitoring display unit 2, such as display settings, historical records, etc. One end of the fourth memory 529 is connected to the first power controller 21 to obtain power, and the other end is bidirectionally connected to the fourth management module 501 through the SPI interface to realize data transmission and interaction; the second display screen 522 is a core component for displaying images and information.

It is connected to the first power controller 21, the fourth communication module 505, and the fourth display load component 27, etc., so as to control each module and transmit data; the fourth communication module 505 (RF module built-in SOC126) is mainly used to realize wireless communication between the monitoring display unit 2 and other devices (such as the camera unit 1), it is connected to the fourth management module 501, receives and sends relevant data information, and the fourth power manager 509 in the third power management component 26 is connected to the fourth charging manager 511 and the first power controller 21 as the power management core, and is connected to the external power adapter 125 at the same time.

The sixth button 516 is connected to the GPIO interface of the fourth communication module 505, and the seventh button 521 is connected to the GPIO interface of the fourth management module 501. Therefore, when the fourth communication module 505 controls the first power controller 21 to enter the low power consumption mode, the fourth display load component 27 and the fourth management module 501 stop running, and there is no audio input and output, which effectively saves power consumption and achieves the purpose of power saving.

[0097] Reference Figure 4 In one embodiment, the fourth display load component 27 includes a second sound pressure indicator light 517, one end of the second sound pressure indicator light 517 is connected to the first power controller 21, and the other end is connected to the fourth management module 501, and the monitoring display unit 2 also includes a fourth microphone 507 and a fourth speaker 506, and the fourth microphone 507 and the fourth speaker 506 are respectively connected to the fourth management module 501.

[0098] In the above embodiment, the fourth display load component 27 includes a second sound pressure indicator light 517, which is used to intuitively display relevant information of the sound, such as the intensity of the sound. One end of the second sound pressure indicator light 517 is connected to the first power controller 21 to obtain electrical energy, and the other end is connected to the fourth management module 501. The fourth management module 501 receives and processes relevant signals to control its on and off or flashing frequency, etc., so as to provide the user with visual feedback of the sound intensity. The monitoring display unit 2 also includes a fourth microphone 507 and a fourth speaker 506. The fourth microphone 507 is a device for collecting ambient sound. It converts the sound signal into an electrical signal and transmits it to the fourth management module 501 for subsequent processing. The fourth speaker 506 is used to convert the electrical signal processed by the fourth management module 501 into sound and play it out, thereby realizing the sound playing function. The first power controller 21 provides power to the second sound pressure indicator light 517, the fourth microphone 507 and the fourth speaker 506. The second sound pressure indicator light 517 is connected to the fourth management module 501 to receive a control signal to display sound-related information. The sound signal collected by the fourth microphone 507 is transmitted to the fourth management module 501. The fourth management module 501 processes the signal and transmits it to the fourth speaker 506 for playback, so that the various components work together to realize the integration of sound collection, processing and display related functions.

[0099] The processing of video display and audio functions is completed by the fourth management module 501 and the second display screen 522, and their power supply is controlled by the first power controller 21; one is a mode in which audio and video work simultaneously, that is, all circuit modules are powered and in operation (we call this working mode "standard mode", and the working mode here can be defined by any name); second, when the user is not watching the video and monitoring the sound, the fourth communication module 505 enters the sleep mode and disconnects the power supply of the back-end load through the first power controller 21 to reduce power consumption (we call this working mode "ECO mode", and the working mode here can be defined by any name).

[0100] When the monitor display device is set to the ultra-power saving mode of "ECO mode", the sixth button 516 can be used to switch on and off the audio and video functions. When the audio and video functions are turned off, the GPIO of the fourth communication module 505 will output a signal to control the first power controller 21 to disconnect the fourth display load component 27 and the fourth management module 501 from the back-end load, and then the fourth communication module 505 will enter the sleep mode; after the fourth communication module 505 enters the sleep mode, the user can wake up the fourth communication module 505 at any time by operating the sixth button 516. After waking up, all circuits will resume power supply and enter the working state, and complete the display or transmission of audio, video and data; in addition, if the fourth communication module 505 receives a trigger signal to wake up the monitor display device from the same frequency hopping spread spectrum network camera device (the wake-up signal here includes but is not limited to audio data, ambient temperature, ambient illumination, ambient humidity, heart rate, blood oxygen, respiratory rate, body temperature, snoring, moving, flipping, falling, sleeping position, standing position, sitting position, switch state), the fourth communication module 505 will also wake up and put all circuits into the working state, and complete the display or transmission of audio, video and data.

[0101] Therefore, the present invention is based on the demand that users sometimes do not need to view the video and sound functions (which we call "ECO mode") during use, and controls the first power controller 21 and the fourth communication module 505 to enter the sleep mode to reduce the overall power consumption and achieve the purpose of ultra-power saving through the fourth communication module 505. The second sound pressure indicator light 517 can display information such as sound intensity in real time through the connection with the first power controller 21 and the fourth management module 501, so that the user can intuitively understand the sound conditions in the monitored area without relying on the auditory perception of sound, especially in noisy environments or scenarios requiring silent monitoring, providing a more convenient sound monitoring method. The fourth microphone 507 and the fourth speaker 506 are set so that the monitoring display unit 2 has audio collection and playback functions. The user can hear the sound in the monitored area and can also play prompt sounds through the speaker, etc., which enhances the practicality and functionality of the baby monitor with power saving mode and dim full-color, and provides more comprehensive information for the monitoring scene.

[0102] Reference Figure 5 In one embodiment, the image processing module in the camera communication module includes an image signal processor 131, a video processor 132 and a video encoder 133. One end of the image signal processor 131 is connected to the image acquisition sensor of the camera unit 1, and the other end is connected to the video processor 132. The video processor 132 is connected to the video encoder 133.

[0103] In the above embodiment, the image processing module in the camera communication module includes an image signal processor 131, a video processor 132 and a video encoder 133, wherein the image processing module is a first image processing module 102 and a second image processing module 202, the image acquisition sensor of the camera unit 1 is a first image acquisition sensor 122 and a second image acquisition sensor 222, the image signal processor 131 is the front-end link of image processing, one end of which is connected to the image acquisition sensor and receives the original image signal. It performs preliminary processing on the signal obtained by the image acquisition sensor, such as amplifying and reducing noise on the signal to improve the image quality; the video processor 132 is located after the image signal processor 131, and it receives the signal processed by the image signal processor 131 and processes the video. The frame rate, resolution and other parameters can be adjusted, and color correction and other processing may be performed to further optimize the video image; the video encoder 133 is connected to the video processor 132, which encodes the video data processed by the video processor 132 and converts it into a format suitable for transmission and storage, so that it can be subsequently transmitted between different devices or stored locally. The image signal collected by the image acquisition sensor is first transmitted to the image signal processor 131, and the image signal processor 131 passes the signal to the video processor 132 after processing. After the video processor 132 further processes the video, the data is transmitted to the video encoder 133, ensuring the orderly processing process of the image from acquisition to final encoding. Each link gradually improves and optimizes the image quality to meet the image requirements of the monitoring system.

[0104] The main components of the image processing module are selected to improve the brightness of the image. A high-sensitivity image acquisition sensor and a large-aperture lens are used to increase the amount of light entering as much as possible to improve the brightness of the image. When in use, there needs to be weak visible light in the environment. The person or object in front of the camera is reflected by the weak light and passes through the large-aperture lens. After being recognized by the high-sensitivity image acquisition sensor, it is transmitted to the image processing module and completed by the internal ISP image signal processor 131 as follows:

[0105] The photosensitivity gain is dynamically enhanced to the maximum. There will be a lot of noise and bad pixels at this time. Then adjust the 3D strong noise reduction process to remove the noise and bad pixels. Then reduce the video frame rate to extend the exposure time of each frame image to lengthen the AE exposure value to increase the brightness. Since the reduction of frame rate and the extension of AE exposure time will produce smear, at this time, increase the ISO value and repeatedly adjust the frame rate and AE exposure time to find a balance point for the best parameter configuration. Then complete the automatic white balance (AWB) adjustment, color and color saturation correction (Color correction) and optimization to achieve the best image restoration and color effect.

[0106] The image processed by the image signal processor 131 and the video data after color effect restoration are transmitted to the video processor 132 and then processed separately in each block, completing the secondary optimization of the block as follows:

[0107] First, convert the video data into an image in YUV format and amplify the YUV image signal. Then divide the image into N+1 (N= or >0) small blocks of 16x16 pixels and optimize each small block separately. After partitioning, each block will complete the corresponding gain adjustment according to the status of different blocks to increase the brightness and color saturation of each block. Then, the noise generated by automatic gain adjustment is suppressed and blurred through parameter adjustment. Then, the object is outlined by the edge algorithm, and the snowflake noise caused by the brightness and color saturation of each block due to gain adjustment is blurred and the edges are sharpened, so that the image restoration, brightness and color effects are optimized to achieve low-light full-color image video. The above completed image video is transmitted to the encoder to complete video encoding and then sent to each channel for use by the backend.

[0108] Through the sequential processing of the image signal processor 131, the video processor 132 and the video encoder 133, the captured images can be optimized in many aspects, including noise reduction, color correction, frame rate and resolution adjustment, etc., thereby significantly improving the image quality. The video encoder 133 converts the processed video data into a suitable format for easy transmission and storage between different devices, thereby improving the versatility and adaptability of the data and ensuring that the monitoring images can be normally displayed and used on various devices.
