The Implementation of LED Color Constancy Algorithms Based on FPGA

In recent years, image processing is more and more widely used in various aspects of the IT industry, and has aroused great attention of insiders, image processing research has been rapidly developed. Meanwhile, the rapid development of programmable logic devices, such as FPGA, makes the hardware implementation of image processing possible. Today, FPGA-based image processing research has become a hot area at home and abroad. In this context, this paper briefly introduces the theoretical basis of the image color constancy algorithm, the image display usage -the development process and driving principle and manner of LED large screen. Subsequently, the paper introduced the achievement of single-scale Retinex(SSR) algorithm on FPGA. It has a more specific elaboration of FPGA hardware platform for system design. Finally, in the last chapter gives a summary overview and system improvements envisaged to improve the system's flexibility and practicality, as well as provide a broader platform for further research.
