摘　　要：首先简要的介绍了监控系统开发平台ADSP-BF533以及OmniVision公司一款图像传感器芯片OV9653,接着阐述了如何在平台上实现图像的采集与压缩。重点讲述了采用软件的方式模拟SCCB总线协议,以实现对OV9653的寄存器配置,然后对JPEG压缩算法进行了分析和实验,使得在保证图像质量的情况下,尽可能提高压缩比,以利于图像进行远程传输。It is introduced the monitoring system＇s platform ADSP-BF533 and a image transducer chip OV9653 of OmniVision Company at first,then explained how to implement image collection and compression on the platform.In order to realize the register disposition to OV9653,it is especially introduced the simulation of the SCCB bus agreement in software.Under the condition of ensuring good quality of the image,this paper has analysised JPEG algorithm and raised the compression ratio as much as possible to transmit image long-rangely and conveniently.
