文档介绍：基于ARM的图像采集系统
摘要
近年来,随着科学技术的不断发展,人们对于生活的安全、方便、快捷的要求越来越高,图像采集已经越来越多地用于智能家居、图像识别、环境监控等领域。
本文通过研究当前数字图像采集系统的研究成果和发展趋势,设计了一种基于ARM的数字图像采集系统,论文重点研究了系统的软件实现。为了克服传统图像采集系统的不足,本文采用常见的USB摄像头作为图像采集设备,利用FS_s5pc100开发板进行操作系统移植, 采用s5pc100芯片直接控制USB摄像头进行图像数据采集,经格式转化后,通过LCD控制器在液晶显示屏上显示。该系统使用主控芯片完成了图像采集和传送,实现的系统贴近于生活,具有一定的实用价值。

Image Capture System Based on ARM
Abstract:In recent years, with the continuous development of science and technology,people have increasingly higher demands for security, convenience, speedy of life. Image acquisition has been increasingly used in smart home, image recognition, environmental monitoring and other fields.
In this paper, I will design a digital image acquisition system based on ARM by studying the current research results and developing trend of digital image acquisition system,and I focus on the software implementation of the system .In order to e the deficiency of the traditional image acquisition system ,I choose USB camera as the image acquisition device ,and transplant OS into the FS_s5pc100 board in this paper .The main control chip , s5pc100 ,controls the USB camera to capture image first,and then it changes the image format and controls the LCD displayer to show the picture . With the only main control chip ,the system can capture and display images , this makes the system have practical implications and more closer to our true life.
