Design of A SoC Chip for Infrared Image Processing in Integrated Infrared Imaging System
With the widespread application of infrared imaging technology in fields such as night vision surveillance and industrial inspection, there is increasing demand for integrated infrared imaging systems. This paper presents the design of an infrared image-processing System-on-Chip tailored for integrated infrared imaging applications. The chip integrates a CPU, an Image Signal Processing co-processor, and dedicated peripheral control interfaces, enabling the monolithic implementation of real-time functions, including infrared detector control, image acquisition, adaptive non-uniformity correction, adaptive blind pixel recognition and compensation, and image enhancement. This integration significantly simplifies the architecture of the infrared detection signal processing system, reduces power consumption and cost, and provides a technical foundation for realizing integrated infrared imaging systems. Fabricated using a 40-nm CMOS process, the chip occupies an area of 4 000 μm × 6 800 μm. Experimental results demonstrate that the chip achieved a post-processing non-uniformity of 0.14% and blind pixel rate of 0.19%, meeting the expected requirements for infrared image processing performance.
