The invention comprises a made-in-China infrared detector analog output self-adaptive adjustment device and a made-in-China infrared detector analog output self-adaptive adjustment method. The made-in-China infrared detector analog output self-adaptive adjustment device comprises a made-in-China infrared detector, a temperature sensor chip, an FPGA and an A/D chip, wherein the FPGA is connected with the infrared detector, the temperature sensor chip and the A/D chip, the A/D chip is connected with the infrared detector, the FPGA generates clock signals, driving signals and the like to drive the infrared detector, the temperature sensor chip and the A/D chip to operate, the infrared detector generates an analog image signal which is converted into a digital image signal after sampling and quantifying by means of the A/D chip, the temperature sensor chip senses the temperature of the infrared detector and converts the temperature into a digital signal which is decoded by the FPGA, and the FPGA receives the digital image signal and performs image processing on the digital image signal. The made-in-China infrared detector analog output self-adaptive adjustment device and the made-in-China infrared detector analog output self-adaptive adjustment method achieve the beneficial effect that the analog output of the infrared detector can be adjusted to be within a two-point parameter calibration range whether the working environment temperature is the same as the environment temperature in calibration or whether the temperature of an observation scene exceeds a temperature range of a black body in two-point calibration, thus response of pixels of the infrared detection can be corrected accurately.
