Automatic light-filling-in night-vision device

Abstract

The invention discloses an automatic light-filling-in night-vision device. The device comprises an object lens, a CCD imaging module, a master control ASIC, an infrared illuminating apparatus, an illuminance detection head, a microphone, a minitype liquid crystal display, an eye lens and a power source module. According to the automatic light-filling-in night-vision device, the amplification function of the CCD imaging module and the amplification times of the object lens are utilized for conducting multiplication calculation, firstly light rays collected by the object lens can be amplified psychically, namely the light rays are amplified through the object lens, then after being converted into digital signals, the light rays are amplified through the amplification function of the CCD imaging module, so that the object lens with low magnification can be utilized for achieving the same amplification times, under the condition of the same requirements, the length of the object lens is shortened, and the size of the object lens is decreased; the infrared illuminating apparatus can also be started for conducting auxiliary shooting, the environment adaptation capability of the night-vision device is greatly improved, and the application scope of the device is expanded.

Description

technical field [0001] The invention relates to an imaging device, in particular to a night vision device for automatically 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 very weak, b...
