Embodiment

[0029] Such as figure 1As shown, a night vision device for automatic cleaning and supplementary light of the present invention includes an objective lens, the model of which is 5*42mm monocular, and the magnification factor is 5 times, which is used to collect the video signal at the target and enlarge it by adjusting the focal length The imaging multiple of the target; CCD imaging module: convert optical signals into digital electrical signals to realize image acquisition, storage, transmission, processing and reproduction; install an illumination detection head, which detects the illumination intensity of the monitored area, And transmit the collected light intensity to the main control ASIC; the main control ASIC makes a judgment according to the received light intensity of the monitored area of ​​the light detection head. When it is greater than the set intensity, it will not act. Intensity value, control the infrared illuminator of the CCD imaging module to supplement inf...

Abstract

The invention discloses a night-vision device capable of cleaning and filling in light automatically. The device comprises an object lens, a CCD imaging module, a master control ASIC, an infrared illuminating apparatus, a cleaning fluid storing device, a cleaning liquid ejector, an illuminance detection head, a microphone, a minitype liquid crystal display, an eye lens and a power source module. By arranging the cleaning fluid storing device additionally in the device, when in a rainy day or in a heavily dewy day, ejection action of the cleaning liquid ejector is controlled through the master control ASIC, cleaning liquid in the cleaning fluid storing device is ejected to the surface of the object lens, a cleaning liquid layer is formed on the surface of the object lens, due to the fact that the cleaning liquid is large in tension, the flow velocity of water drops on the surface of the object lens can be sped up, so that rainwater or fog water cannot adhere to the surface of the lens, and the shot image quality under the rainy or foggy environment is improved.

Description

technical field [0001] The invention relates to an imaging device, in particular to a night vision device for automatically cleaning and supplementing light. Background technique [0002] The night vision device is a nighttime external sight with an image intensifier as the core device, and uses the light reflected by the target under weak light to be enhanced into a visible image that the human eye can perceive on the fluorescent screen through the image intensifier to observe and aim at the target. Infrared night vision device is a military night vision device using photoelectric conversion technology. It is divided into two types: active and passive: the former uses infrared searchlights to irradiate the target, and receives reflected infrared radiation to form an image; the latter does not emit infrared rays, but relies on the target's own infrared radiation to form a "thermal image", so it is also called "thermal image". instrument". [0003] Visible light at night is...
