[0097] For the convenience of understanding, the data transmission relationship inside this infrared sight is described as follows:

[0098] After the infrared detector receives infrared radiation, it generates a video signal through photoelectric conversion. After the video signal undergoes processing such as A / D conversion, uniformity correction, blind pixel replacement, gain adjustment, and brightness adjustment transformation by the signal processor inside the infrared detector, it is then converted into a digital signal by the digital video chip inside the infrared detector. The digital signal is transmitted to the movement signal board through DVP. Then, the ISP chip inside the movement signal board generates image data and temperature data according to the digital signal. The image data is transmitted to the main control board via the movement interface board; after receiving the image data, the main control board processes it through digital image processing technology and digital image enhancement technology, and transmits the processed image data to the display screen 27 for display via the display screen 27.

[0099] Among them, the main control board takes ARM as the core to realize the control of the entire circuit part. The ARM processing unit consists of an SOC processing chip and necessary peripheral devices such as DDR, EMMC, and RTC, and mainly realizes functions such as pseudo-color switching, picture-in-picture function, photographing, video recording, rough ranging, and power-on self-check.
