An Optimized Video Capture and Preprocessing Strategy Based on FPGA

Abstract

The video capture and preprocessing is the basis of video process system. This paper analyzes the timing of video capture by Camera Link interface based on FPGA, and proposed an automatic error detection approach to avoid error accumulation during the video data capture. Furthermore, by adopting the optimized LUT and pipeline addition, an optimized method for RGB to YCbCr color space conversion (CSC) is presented specifically for the video format preprocessing. Experimental results demonstrate that the strategy we proposed is of high reliability, and it could obtain maximum operation frequency of 334MHz, 3.16 times faster than the direct method.
