Abstract :
To absolve image blur of high speed camera, fixed-point DSP TMS320C6416 and Wiener filtering algorithm are adopted. Degeneration model for moving blur is researched; the principle of Wiener filtering is explained: how to complete FFT of 32bit and how to exert DMA function of DSP to enhance processing speed; ringing effect and edge effect are analyzed, and the test results are presented.
