摘　　要：利用嵌入式芯片构成图像采集系统,实现了图像采集的实时性、连续性和高分辨率。该系统采用CMOS图像传感器芯片,将采集到的图像信号经过一系列处理并输出,通过嵌入式芯片S3C2440接收图像传感器输出的数字信号流,利用ARM920T S3C2440A提供的视频采集控制逻辑,实现了对图像信息的实时采集,且系统使用网络接口芯片实现了信息的远程传输、远程控制及视频采集,可以通过这些接口来扩展系统功能。Using the image collection system structured by embedded chip,the real time performance,continuity and high resolution of image collection were realized.The CMOS image sensor chip was used to process and send out the collected image signals.The digital signal flow sent by image sensor was received by the embedded chip S3C2440,and use of the video provided by the ARM920T S3C2440A the control logic was collected,so that the real time collection of image was realized.Moreover,using the network interface chip,the remote transmission,remote control and video capture of the information were also realized.The system function can be extended through these interfaces.
