FPGA-Based High Definition Image Processing System

Abstract

With the continuous development of mobile communication and the Internet, people’s requirements for the speed and quality of digital image processing are increasingly improved. A large amount of high-speed, parallel video stream data needs to be processed in real time, especially in video image processing. The author presents a method of high-definition image transmission and processing system based on FPGA. The system uses FPGA as the main controller, consisting of front-end HDMI video receiving module, image fast median filtering processing module, image ping pong Storage module and HD-SDI video display module through hardware description language programming, effectively realizing real-time video capture, transmission and display. It has been verified that the processing and transmission of digital video signals in this system is stable and reliable. The system also has a series of advantages such as low power consumption, low cost, flexible design, and easy expansion and has been applied in practical engineering.
