Design and implementation of video capture board based on ARM

摘要

This paper presents a video capture board to implement the embedded system video capture. We apply the video capture board to realize the high quality image acquisition with simple structure. In this paper, analogue video signals are converted to digital image data by Philips SAA7113H and image data is collected by camera interface(CAMIF) of Samsung ARM processor based on S3C2440 core which guarantee the board to collect images reliably and stably. It is applicable to a broad class of video source collecting. The hardware circuit diagram, driver program and data transmission optimized method are also introduced. We have tested our board in experiment and with promising result in terms of quality of images, stability and reliability.
