Description

Technical Field

[0001] The utility model relates to the technical field of night vision devices, in particular to a low-light night vision imaging system. Background Art

[0002] A low-light night vision device is a device specifically designed to observe objects under low-light conditions. It provides clear visual effects by enhancing weak light (such as starlight or moonlight). Currently, low-light night vision devices are mainly divided into two types. One is to achieve low-light night vision through a microscopic image intensifier, and the other is to achieve low-light night vision through the cooperation of an imaging chip and a display screen. Among them, the first type of low-light night vision device has a complex structure and high cost, so it is usually used in reconnaissance, observation, aiming, vehicle driving, and other battlefield operations; the second type of low-light night vision device has a simple structure and an infrared supplementary light source, so it is usually used for wildlife observation.

The end of the display screen 113 for display is arranged in cooperation with the end where light enters the eyepiece 103.

[0066] Among them, the imaging chip 111 adopts an RGB-IR imaging chip in the prior art (for example: OV4689, OV9712). This imaging chip 111 can generate an RGB image and an IR infrared black-and-white image simultaneously.

[0067] Preferably, both the RGB output end and the IR output end of the imaging chip 111 are connected to the signal input end of the image processor 112.

[0068] By connecting both the RGB output end and the IR output end of this chip to the signal input end of the image processor 112, data signals of the RGB image signal and the IR infrared black-and-white image can be respectively transmitted to the image processor 112;

[0069] The image processor 112 can adopt an image processor 112 in the prior art that can implement the functions of the present utility model (for example: Hi3516DV300, Hi3518C).

[0070] Through the image processor 112, the color information of each pixel point in the RGB image can be extracted and rendered into the IR infrared black-and-white image, thereby obtaining a composite image.

[0071] Preferably, the signal output end of the image processor 112 is connected to the signal input end of the display screen 113.

[0074] During use, an objective lens 104 that can simultaneously collect visible light and near-infrared light is adopted, which can facilitate the imaging chip 111 to generate an RGB image and an IR infrared black-and-white image.

[0075] At the same time, the RGB-IR imaging chip can separately output the signals of the RGB image and the IR infrared black-and-white image, that is, the RGB-IR imaging chip can separately output two images, namely the RGB image and the IR infrared black-and-white image.

[0076] Then, both of the two collected images are input into the image processor 112. After being processed by the image processor 112, the color information of each pixel point in the RGB image can be extracted and rendered into the IR infrared black-and-white image, thereby obtaining a composite image.

[0077] Then, the composite image is output to the display screen 113 for display, so that the behavior of animals at night can be observed more clearly.
