摘　　要：由于嵌入式系统的系统资源的有限性,系统上的摄像头设备多通过插值等方法获得伪高分辨率,无法满足文字识别应用的需求。为解决这个问题,文章首先分析了S3C6410嵌入式处理器的camera模块接口的特性,介绍其与CMOS摄像头的硬件连接方法,并在Windows CE6.0操作系统上采用Direct Show技术设计并实现了500万像素高分辨率摄像头驱动。通过实验进行验证分析,结果表明该摄像头驱动运行稳定,对其获得的文字图片进行识别,测试结果显示识别率达到99.5%。On account of the limitation of system resources in embedded platforms,methods like interpolation are commonly applied to obtain pseudo-high-resolution images,but which cannot meet the requirements of character recognition.In order to solve this problem,the thesis firstly analyzes the camera module interface features of the embedded processor S3C6410,and then introduces the connection method between the camera module interface and CMOS camera hardware.With the application of Direct Show technology in Windows CE6.0,the driver for high-resolution cameras（up to 5 million pixels）has been developed.A verification experiment has been conducted and the result indicates that the camera driver has both high reusability and high stability.A testing experiment has been conducted to verify the high resolution and the result shows that the recognition rate is up to 99.5%.
