基于ARM-Linux的视频的采集与显示系统

摘要

随着嵌入式系统的逐步发展,实现在嵌入式系统上的视频采集与显示能够提高嵌入式的应用范围与实用性.基于这个目的,设计了基于S3C2440控制芯片、Linux操作系统的视频采集与显示系统,对PAL制式的模拟摄像头进行信号采集和解码,然后显示在LCD显示屏上.根据视频显示测试结果,该系统具有稳定性好、可移植等优点,在生产生活中有较高的实用价值.%With the development of the using of embedded system,its application range and practicality can be improved by implement the function of capture and playback the video.Based on this purpose,a video capture and playback system,that collect video signals from a PAL-formed camera and display the video after decoding the signal,is designed based on S3C2440 microchip and Linux operating system.According to test results of video capture and playback,the system have the advantage of having high reliability and portability,so have widely practical use.
