Description

Technical Field

[0001] This utility model relates to the field of photography, and in particular to a convenient handheld night vision camera. Background Technology

[0002] In many situations, photographers need to capture moments that occur in low light or at night. Ordinary cameras often fall short in these conditions. To address this need, night vision cameras have become invaluable tools thanks to continuous technological advancements. A night vision camera is a special type of camera that can capture clear, vivid images in low-light or complete darkness.

[0003] The main feature of night vision cameras is their light sensor. These sensors are more sensitive than those in ordinary cameras, capturing more light and thus producing clear, bright images even in low-light or dark environments. Furthermore, night vision cameras have a higher dynamic range, allowing them to capture both bright and dark areas simultaneously, resulting in more realistic and vivid images.

[0004] Night vision cameras have wide applications in many fields. For example, in security surveillance, night vision action cameras can be used to monitor dark areas or nighttime events, providing valuable support to police and security personnel. In wildlife research, night vision action cameras can be used to record animal behavior and activities, allowing scientists to better understand their habits and ecological behaviors. Furthermore, in outdoor sports, night vision cameras can also be used to capture beautiful natural scenery such as starry skies and sunrises.

[0005] In short, night vision cameras are powerful photographic tools that allow us to capture vivid images in low-light or nighttime environments. They have a wide range of applications, from security surveillance and wildlife research to outdoor activities.

[0006] Traditional night vision cameras include an acquisition module for image capture. The images captured by the acquisition module are processed by an internal processor and then displayed in real time on an internal display screen. The real-time images can only be viewed through the internal display screen. If a team is shooting, only the user can see the image. If others want to see it, the user needs to be replaced, which is inconvenient. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0030] This utility model provides a convenient handheld night vision camera. The night vision camera is applicable in various fields such as military, security, wildlife observation, and automotive night vision assistance, used to assist in capturing images in dark environments at night. It includes: a body 1; an acquisition module 2, installed inside the body 1, equipped with a photosensitive element 201; a control module 3, installed inside the body 1, equipped with a processor connected to the CMOS sensor; and an observation module 4, equipped with an inner screen 401 and an outer screen 402. The inner screen 401 is located inside the body 1, and the outer screen 402 is located on the outer surface of the body 1. The processor is connected to both the inner screen 401 and the outer screen 402. The body 1 protects and supports other auxiliary modules. The acquisition module 2 is used to capture environmental images, the control module 3 is used to control other working modules and process images, and the observation module 4 is used to observe images.

[0031] In implementation, an acquisition module 2, a control module 3, and an observation module 4 are installed inside the main body 1. The photosensitive element 201 is connected to the processor. An inner screen 401 is installed inside the main body 1 and connected to the processor. An outer screen 402 is installed on the outer surface of the main body 1 and connected to the processor. The user captures images of the nighttime environment through the acquisition module 2.

The electrical signal is transmitted to the processor, which further processes the electrical signal transmitted from the photosensitive element 201. The processor synchronously transmits the processed image to the inner screen 401 and the outer screen 402. The inner screen 401 and the outer screen 402 display the captured image simultaneously. The user can see the image captured by the inner screen 401, while an observer next to the user can see the captured image by the outer screen 402. This allows both the user and the observer to observe the image simultaneously, achieving two-way observation and improving convenience.

[0032] Furthermore, the photosensitive element 201 is a CMOS sensor. CMOS (Complementary Metal-Oxide-Semi-conductor) sensors are widely used in imaging devices (such as cameras, mobile phone cameras, night vision devices, etc.). The processor is a digital signal processor (DSP). The inner screen 401 is an LCD display, and the outer screen 402 is also an LCD display. Objective lens 102 and eyepiece 103 are respectively located at both ends of the body 1. Objective lens 102 is coaxially arranged with photosensitive element 201, and eyepiece 103 is coaxially arranged with inner screen 401.

[0033] Light is projected through objective lens 102 onto photosensitive element 201. Objective lens 102 is used for focusing and collecting light, and eyepiece 103 is used for user observation. Buttons are provided on the outer surface of the body 1, and a PCB board is provided inside the body 1. The buttons are connected to the PCB board, and a control circuit is provided on the PCB board. The control circuit is electrically connected to the acquisition module 2, control module 3, and observation module 4. The buttons are used to turn each module on, off, and adjust it. The surface of the body 1 is provided with anti-slip texture. A strap is provided on one side of the body 1 to fix the palm, making it stable during use and preventing it from falling. An AD autofocus module is also provided inside the body 1. The AD autofocus module can quickly and accurately lock onto the target object, especially when shooting moving objects or scenes that change rapidly.

[0034] In some embodiments, the outer surface of the body 1 is provided with a pivot 101, and one side of the outer screen 402 is hinged to the pivot 101.

[0035] In practice, a pivot 101 is set on the outer surface of the body 1 to hinge the outer screen 402 to the pivot 101. The outer screen 402 can be flipped on the pivot 101. When in use, the outer screen 402 can be flipped open for viewing. When not in use, the outer screen 402 can be folded up so that the screen surface of the outer screen 402 is close to the overall surface, thereby protecting the screen surface of the outer screen 402 and making the whole unit easy to store.

[0036] Furthermore, the outer screen 402 is connected to the pivot 101 via a connector, and a sub-pivot 101 is provided on the connector. The outer screen 402 is connected to the sub-pivot 101, and the outer screen 402 can be flipped on the sub-pivot 101, thereby realizing the dual-axis flipping of the outer screen 402.

[0037] In some embodiments, the body 1 is equipped with a ranging module 5, which is connected to the processor. The ranging module 5 includes a lens barrel 501, a transmitter, and a receiver, with the transmitter and receiver mounted on one side of the lens barrel 501.

[0038] In practice, the infrared lens tube 501 is installed inside the unit, and the transmitter and receiver are installed inside the lens tube 501. The transmitter is used to emit modulated infrared light, and the receiver receives the infrared light. After the transmitter emits infrared light, it illuminates the target and reflects back to be received by the receiver. By accurately measuring the phase difference between the emitted light and the reflected light, the distance to the target can be calculated. Accurately measuring the distance to the target helps to improve the shooting effect and helps to judge the real-time dynamics of the target, which is particularly prominent in security or military applications.

[0039] Furthermore, one end of the lens barrel 501 is provided with a transmitting lens 502 and a receiving lens 503. The infrared light emitted by the transmitter passes through the transmitting lens 502, and the reflected infrared light passes through the receiving lens and is received by the receiver inside the lens barrel 501. After acquiring the measured distance, the ranging module 5 informs the processor of the measured distance through UART communication. UART (Universal Asynchronous Receiver / Transmitter) is a widely used serial communication protocol used to transmit data between devices.

[0040] In some embodiments, the body 1 is equipped with an infrared supplementary lighting unit 6.

[0041] In practice, an infrared illumination unit 6 is installed on the camera body 1. This unit provides supplemental infrared light to the camera. In complete darkness, the infrared illumination unit 6 can assist the camera in capturing the target object by emitting infrared light. The camera generates an image by detecting the infrared light reflected from the object. In low-light conditions, the camera's autofocus system may encounter difficulties. The infrared light emitted by the infrared illumination unit helps the camera's focusing system better detect the outline and details of the subject, thus achieving more accurate focusing.

[0042] In some embodiments, the infrared supplementary lighting unit 6 includes an IR lamp 601 and a lamp holder 602, with the IR lamp 601 mounted on the lamp holder 602.

[0044] In some embodiments, the lamp holder 602 is provided with a rack 603, and the outer wall of the body 1 is provided with a knob 604. The knob 604 is connected to a gear 605, and the gear 605 and the rack 603 mesh.

[0045] In practice, a rack 603 is installed on the lamp holder 602, and a knob 604 is installed on the outer wall of the body 1. The knob 604 can rotate on the outer wall of the body 1. A gear 605 is installed on the knob 604, and the gear 605 meshes with the rack 603. The user can manually rotate the knob 604 on the outer wall of the body 1. The knob 604 drives the gear 605 to rotate, the gear 605 drives the rack 603 to move, and the rack 603 drives the lamp holder 602, ultimately changing the position of the IR lamp 601 on the lamp holder 602. When facing target objects at different distances, the best lighting and imaging effect can be achieved by changing the position of the IR lamp 601. The IR lamp 601 can automatically sense the intensity of external light and realize the switching between black and white and color modes.

[0051] Furthermore, during use, the light signal projected from the objective lens 102 is converted into an electrical signal by the photosensitive element 201, realizing the photoelectric conversion function. The photosensitive element 201 is a CMOS sensor. The signal is then transmitted to the processor, which is a digital signal processor (DSP). The image processed by the processor is then transmitted to both the external and internal screens for display.
