Description

Technical Field

[0001] This invention relates to the field of night vision equipment technology, and more specifically, to an ultra-low illumination handheld dual-screen night vision device. Background Technology

[0002] Traditional handheld night vision devices generally employ a single, fixed single-screen display structure, falling into only two categories: exposed large screens and eyepiece screens. While exposed screens can be viewed independently of the eyes, are comfortable to use, and are applicable to a wide range of scenarios, they exhibit significant glare at night, offer poor concealment, and easily reveal the observation location. Eyepiece screens, on the other hand, provide excellent light protection, privacy, and minimal light leakage, but require prolonged close contact with the eye socket for observation, which can easily cause eye fatigue, pressure discomfort, obstruct monocular vision, and loss of environmental awareness, making them inconvenient to use in public settings and limiting their applicability.

[0003] The existing single-screen display mode is fixed and cannot achieve multi-scenario compatibility. It can only make trade-offs between concealment, comfort and versatility, resulting in poor product experience and limited practicality. Summary of the Invention

[0007] Furthermore, the second display module includes an on state and a off state; When the second display module is in the open state, the second display module can be flipped or rotated at multiple angles; When the second display module is in the off state, the second display module is in a non-working state and is aligned with the main body.

[0008] Furthermore, a light shield is provided at one end of the main body away from the optical imaging component, and is connected to the first display module.

[0009] Furthermore, the first display unit consists of an eyepiece assembly and an eyepiece plate, with the eyepiece plate located behind the eyepiece assembly.

[0010] Furthermore, the insertion interface is located on one side of the main body and is positioned opposite to the second display unit.

[0011] Furthermore, the main body is also equipped with buttons or knobs, which are used to control different functions.

[0012] Furthermore, the CMOS image sensor is a back-illuminated CMOS image sensor, used to improve photon capture efficiency in low-light environments.

[0013] Furthermore, the target surface size of the CMOS image sensor is greater than or equal to 1.5 inches, and the effective resolution is 1920×1080.

[0014] Furthermore, the size of the second display unit is smaller than the size of the main body.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0022] Please refer to the attached document. Figures 1-6This invention proposes an ultra-low-light handheld dual-screen night vision device, comprising a main body 100, a motherboard 200, an optical imaging component 300, an image acquisition component 400, an image processing module 500, a display module 600, a power supply module 2000, and an external module 700. The motherboard 200 is located within the main body 100. The optical imaging component 300 and the image acquisition component 400 are arranged along the optical axis and are detachably locked to the main body 100. The image acquisition component 400 and the image processing module 500 are respectively located within the main body 100 and are electrically connected. The image processing module 500 is located on the motherboard 200. The display module 600 and the external module 700 are respectively connected to the motherboard 200. The power supply module 2000 is located within the main body 100 and supplies power to the power supply module. The display module 600 includes a first display module 610 and a second display module 600. The first display module 610 includes a first control unit 611 and a first display unit 612; the second display module 620 includes a second control unit 621 and a second display unit 622; the first control unit 611 independently drives the first display unit 612 and forms a first display path; the second control unit 621 independently drives the second display unit 622 and forms a second display path; the first display path and the second display path are respectively connected to the image processing module 500 for transmitting image data; the first display module 610 is located at one end of the main body 100, and the second display module 620 is located on one side of the main body 100; the external module 700 includes a laser module 710 and a 4G communication module 720, the laser module 710 is used to measure distance, and the 4G communication module 720 is used to realize real-time data transmission; the main body 100 is provided with an interface 110 for communication between the external module 700 and the motherboard 200.

[0023] In this embodiment, the optical imaging component 300 and the image acquisition component 400 are arranged sequentially along the optical axis. External light signals are converged by the optical imaging component 300 and input to the image acquisition component 400. The image acquisition component 400 converts the light signals into electrical signals and transmits them to the image processing module 500. The image processing module 500 processes the image signals and outputs them to the display module 600 for display. The image acquisition component 400 includes an image enhancement unit and a CMOS image sensor. The CMOS image sensor is used to acquire the light signals obtained by the optical imaging component 300 and output the original image signal. Compared to CCD technology, CMOS sensors have advantages in image capture flexibility, sensitivity, dynamic range, resolution, power consumption, and system integration. The image enhancement unit amplifies weak light signals in the environment to obtain an enhanced image signal. By simultaneously acquiring original and enhanced image information, a richer data source is provided for subsequent image processing.

[0024] The image processing module 500 is connected to both the image enhancement unit and the CMOS image sensor, and is used to fuse the enhanced image signal with the original image signal. By performing temporal overlay and spatial denoising on multiple consecutive frames of images, the signal-to-noise ratio of the image is effectively improved, and random noise generated in low-light environments is reduced. The image processing module 500 is located on the motherboard 200 within the main body 100. The motherboard 200 also integrates functions such as Beidou navigation, gyroscope, electronic compass, and recording. The image processing module 500 can also perform motion compensation on consecutive image frames based on the attitude information output by the gyroscope, thereby reducing the impact of device jitter on image quality and ensuring image stability.

[0025] The external module 700 includes a laser module 710 and a 4G communication module 720. The laser module 710 is used to emit laser signals to the target area and receive reflected signals to obtain target distance information; the 4G communication module 720 is used to interact with a remote server.

[0026] The display module 600 includes a first display module 610 and a second display module 620. The first display module 610 includes a first control unit 611 and a first display unit 612. The second display module 620 includes a second control unit 621 and a second display unit 622. The first control unit 611 and the second control unit 621 are respectively located on the motherboard 200, and the first display unit 612 and the second display unit 622 are located on the main body 100. The first control unit 611 independently controls the first display unit 612 and forms a first display path; the second control unit 621 independently controls the second display unit 622 and forms a second display path. The image processing module 500 establishes independent data connections with the first control unit 611 and the second control unit 621, respectively. Specifically, the image processing module 500 has two independent data output ports, which are respectively connected to the signal input terminals of the first control unit 611 and the second control unit 621, enabling it to simultaneously output different or the same image data to the two display control units, meeting the needs of dual-screen display or simultaneous display. The image processing module 500 writes the image data into the data channels of the first display path and the second display path respectively. The first control unit 611 and the second control unit 621 output the image information in parallel without affecting each other.

[0027] Furthermore, the first display unit 612 is an eyepiece screen, composed of an eyepiece assembly 6121. An eyepiece plate 6122 is located behind the eyepiece screen. The image processing module 500 transmits image information to the eyepiece plate 6122 through the first display path, illuminating the eyepiece plate 6122 and forming a small image. The light emitted from the eyepiece plate 6122 is optically magnified and collimated by the eyepiece assembly 6121, converting the image light emitted from the eyepiece plate 6122 into parallel light suitable for human observation. Ultimately, a magnified and clear virtual image is formed on the retina of the human eye, enabling comfortable close-range observation. The top of the main body 100 is equipped with buttons 900 and knobs 1000, respectively used to control the eyepiece plate 6122 of the first display unit 612, to realize functions such as status display, photography, video recording, storage, playback, zooming, and settings of the first display unit 612.

[0028] The second display unit 622 adopts a DV-style external viewfinder screen. The mainboard 200 is connected to this DV-style external viewfinder screen via a flexible ribbon cable, enabling the screen to be flipped and folded. The second display unit 622 can adjust the composition and angle of the captured image. In addition, the second display unit 622 is equipped with a control screen, which can be operated to realize functions such as status display, taking pictures, recording videos, storing, playing back, zooming, and setting. It can also be viewed or used as evidence by people in the vicinity in public places. Furthermore, the second display unit 622 can also be controlled via the buttons 900 and knobs 1000 on the main body 100 to realize functions such as status display, taking pictures, recording videos, storing, playing back, zooming, and setting.

[0029] Furthermore, the motherboard 100 is equipped with a linkage control module for the coordinated start and stop of the first display unit 611 and the second display unit 622. When the first display unit 612 is open, the second display unit 622 is turned off; when the second display unit 622 is closed, the first display unit 612 is turned on. This avoids the simultaneous operation of the first and second display units 612, effectively reducing power consumption and improving battery life. Specifically, the linkage control module includes a status detection unit and a linkage control unit. The status detection unit detects the open and closed states of the first and second display units 612 and 622, respectively. The linkage control unit is electrically connected to the first control unit 611 and the second control unit 621. Based on the detection results of the status detection unit, the linkage control unit outputs control commands: when the first display unit 612 is open, the linkage control unit controls the second display unit 622 to automatically close; when the first display unit 612 is closed, the linkage control unit controls the second display unit 622 to automatically open, eliminating the need for manual operation and reducing unnecessary power consumption.

[0030] Furthermore, the main body 100 is also equipped with a TF card slot (microSD card slot), which is mainly used for local data recording and storage expansion.

[0031] Furthermore, the first display module 610 is located at one end of the main body 100, the optical imaging component 300 is located at the other end of the main body 100, and the second display module 620 is located between the first display module 610 and the optical imaging component 300, and the second display module 620 is an external display screen. The optical imaging component 300 is detachably locked to the main body 100, and the connection method is any one of the following: bayonet 120 rotation locking, thread engagement, elastic buckle insertion, or magnetic adhesion, so as to achieve precise optical path alignment and quick disassembly and replacement.

[0032] Furthermore, for high-definition, long-distance observation at night, a large-aperture optical imaging component 300 and a large-area photosensitive element are used, which increases power consumption. To match the high power consumption, it is powered by six 18650 batteries (approximately 15000mAh).

[0033] Please refer to Figure 1 The optical imaging component 300 is used to receive weak light signals from the outside and transmit the light signals to the image acquisition component 400. The image acquisition component 400 includes an image enhancement unit and a CMOS image sensor. The image enhancement unit is used to enhance the weak light signals and output an enhanced image signal. The CMOS image sensor is used to acquire the light signals obtained by the optical imaging component 300 and output the original image signal. The image processing module 500 is connected to the image enhancement unit and the CMOS image sensor respectively, and is used to perform multi-frame fusion processing on the enhanced image signal and the original image signal to generate color image data.

[0034] In practical implementation: the optical imaging component 300 is used to receive weak light signals from the outside world, and to converge and filter the light signals before transmitting them to the image acquisition component 400. The optical imaging component 300 includes an objective lens group, optical filters, and a transmission lens; the objective lens group adopts a multi-element high-transmittance optical glass structure to converge weak natural light such as moonlight and starlight; the optical filters are used to filter out interference signals such as infrared stray light and strong light; and the transmission lens is used to accurately transmit the processed light signals to the image acquisition component 400.

[0035] The optical imaging component 300 and the image acquisition component 400 are arranged along the optical axis. The image acquisition component 400 includes an image enhancement unit and a CMOS image sensor. The image enhancement unit uses microchannel plate and photocathode technology to receive the light signal transmitted by the optical imaging component 300, amplify it into an enhanced image signal and output it. The CMOS image sensor is used to synchronously acquire the light signal transmitted by the optical imaging component 300, convert it into the original image signal and output it.

[0036] The image processing module 500 is electrically connected to both the image enhancement unit and the CMOS image sensor. It employs a high-performance digital signal processor to receive both the enhanced and original image signals. Through adaptive noise reduction, pixel alignment, and multi-frame fusion algorithms, it processes the two signals, combining their advantages to generate color image data. Simultaneously, it can adjust image brightness and contrast to optimize imaging results. Please refer to Figure 5 and Figure 6 The second display module 620 includes an open state and a closed state; when the second display module 620 is in the open state, the second display module 620 can be flipped or rotated at multiple angles; when the second display module 620 is in the closed state, the second display module 620 is in a non-working state and is set to fit against the main body 100.

[0037] In practical implementation: An independent data connection is established between the second display module 620 and the image processing module 500 to enable independent control of the display content and refresh timing of the second display unit 622, ensuring no interference with the first display path. Specifically, the second display unit 622 of the second display module 620 is a small DV-style viewfinder screen capable of displaying image information synchronously or independently. The second display unit 622 is an external structure. When the second display unit 622 of the second display module 620 is in the open state, it can perform functions such as flipping and rotating to adapt to different viewing angles and usage scenarios. Furthermore, the structural movements of the second display unit 622 do not affect its own display function or the working state of the first display unit 612 of the first display module 610. When the second display unit 622 is in the closed state, i.e., when the second display module 620 is not in operation, the second display unit 622 can be folded and fitted into the main body 100.

[0038] Please refer to Figure 4 and Figure 5 A light shield 800 is provided on the end of the main body 100 away from the optical imaging component 300 and is connected to the first display module 610.

[0039] In specific implementation: A light shield 800 is circumferentially arranged on the outer side of the first display unit 612 (i.e., eyepiece screen) of the first display module 610. The light shield 800 is installed at the observation end of the eyepiece screen and has an overall cup-shaped or cylindrical structure that surrounds the human eye. It is made of flexible silicone or soft elastic material and can closely fit the skin around the user's eyes to form a closed light-shielding cavity. Specifically, the light shield 800 is arranged around the observation end of the first display module 610. On the one hand, it blocks strong external light and ambient stray light from entering the optical imaging system of the monocular, avoiding external light interference that causes the observed image to become washed out and the contrast to decrease. On the other hand, it prevents the light displayed inside the eyepiece screen from leaking outward, avoiding light leakage when used at night or in dark places, and improving concealment and observation comfort. The light shield 800 is detachably connected to the housing of the first display unit 612, which facilitates replacement, cleaning, or replacement of the light shield 800 with different sizes according to the user group.

[0040] Please refer to Figure 1 and Figure 2 The first display unit 612 is composed of an eyepiece assembly 6121 and an eyepiece plate 6122, with the eyepiece plate 6122 located behind the eyepiece assembly 6121.

[0041] In practical implementation: the eyepiece plate 6122 is positioned behind the eyepiece assembly 6121 and is driven and outputs image light by the first control unit 611. The eyepiece assembly 6121 also includes an eyepiece lens, a collimating lens, and a distortion correction lens. The eyepiece assembly 6121 magnifies, collimates, and corrects distortion of the image light, converting divergent light into parallel light. The parallel light enters the human eye and focuses on the retina, forming a clear, magnified virtual image on the retina, thus enabling fatigue-free close-range observation.

[0042] Please refer to Figure 3 , Figure 4 and Figure 5 The insertion interface 110 is located on one side of the main body 100 and is positioned opposite to the second display unit 622.

[0043] In practical implementation: the connector 110 is located on the main body 100 and is electrically connected to the motherboard 200. The external module 700 is a pluggable module, connected to the motherboard 200 within the main body 100 via the connector 110. Specifically, the connector 110 is located on the side opposite to the second display module 620, allowing it to avoid folding, rotating, or flipping movements of the second display unit 622 of the second module. The external module 700 includes, but is not limited to, a laser module 710 and a 4G communication module 720. The laser module 710 can quickly measure the straight-line distance to the observed target and provide basic data for electronic compasses, GPS, and coordinate calculations. The 4G communication module 720 can transmit real-time images from the night vision device to a mobile app, command center, or cloud platform for remote viewing, remote command, and remote evidence collection. Furthermore, it can transmit location information in real time for recording movement trajectories. The laser module 710 and the 4G communication module 720, when used together, can form a digital night vision reconnaissance system with ranging, positioning, and remote data transmission capabilities.

[0044] Please refer to Figure 4 The main body 100 is also equipped with a button 900 or a knob 1000 structure, which are used to control different functions.

[0045] Specifically, the button 900 or knob 1000 can independently control the first display unit 612 to turn on or off, or independently control the operation of the second display unit 622, without the need for coordinated control. Simultaneously, by manually operating the button 900 or knob 1000, one can not only switch the display modes (different or simultaneous display) of the first display module 610 and the second display module 620, but also independently control the first display unit 612 or the second display unit 622 to achieve different functions, including but not limited to status display, taking photos, recording videos, storing, playing back, zooming, and setting one or more functions, further enhancing the flexibility of the device.

[0046] Please refer to Figure 1 and Figure 5 The CMOS image sensor is a back-illuminated CMOS image sensor, used to improve photon capture efficiency in low-light environments.

[0047] Specifically, light passes through the optical imaging component 300 and illuminates the photodiodes in each pixel of the CMOS image sensor. Photons strike the silicon material, ejecting electrons from the atoms and creating photogenerated charges. The stronger the light, the more electrons accumulate. In low-light environments, the signal is extremely weak, requiring the CMOS image sensor to improve quantum efficiency to convert as many incoming photons as possible into electrons. The CMOS image sensor achieves this through larger pixels and a back-illuminated structure. The image processing module 500 then performs noise reduction and color reconstruction on the image signal output from the CMOS image sensor, enabling the device to output color images even in low-light environments.

[0048] Furthermore, the CMOS image sensor adopts a BSI back-illuminated structure, which eliminates the light blocking of the metal interconnect layer. Combined with high-transmittance microlenses and anti-reflection films, it improves quantum efficiency, allowing weak visible light to be converted into photoelectric charge more efficiently.

[0049] Please refer to Figure 1 and Figure 5 The CMOS image sensor has a target surface size greater than or equal to 1.5 inches and an effective resolution of 1920×1080.

[0050] In specific implementation: the target surface size of the CMOS image sensor is 1.69 inches, its effective resolution is 1920×1080, and the single pixel size is not less than 10μm, so as to reduce the pixel density and improve the photon collection capability of the unit pixel. The aperture value of the optical imaging component 300 is not greater than F1.4, and its imaging circle covers the entire photosensitive area of ​​the CMOS image sensor, so as to increase the light flux incident on the CMOS image sensor per unit time.

[0051] Please refer to Figure 2 and Figure 5 The size of the second display unit 622 is smaller than the size of the main body 100.

[0052] Specifically, the overall size of the second display unit 622 of the second display module 620 is smaller than the size of the mounting surface on the main body 100 for mounting the second display unit 622. After installation, the second display unit 622 does not exceed the outline of the mounting body 100 to adapt to the overall structural layout of the device. Specifically, the mounting body 100 is provided with a mounting surface for mounting the second display unit 622. The mounting surface has a rectangular structure, and the overall size of the second display unit 622 is smaller than the size of this mounting surface to avoid damage caused by the second display unit 622 protruding from the mounting body 100, while also optimizing the neatness of the overall appearance of the device.

[0053] Furthermore, a bayonet 120 is provided on the side of the main body 100 near the insertion interface 110 for mounting a hand strap, thus addressing issues such as slippage, poor fit, and lack of protection. Specifically, the second display unit 622 is located on one side of the main body 100, and the bayonet 120 is located on the side opposite to the second display unit 622, i.e., the second display unit 622 and the bayonet 120 are respectively located on the left and right sides of the main body 100. The bayonet 120 avoids the mounting position of the second display unit 622 and will not affect the normal operation of the second display unit 622. The size of the hand strap is adjustable, and the adjustment range covers most adult hand sizes to ensure fit.
