摘　　要：随着现代图像采集技术的迅速发展,CMOS图像传感器正在得到越来越广的应用。但目前绝大多数控制器没有SCCB总线接口,给其应用带来一定的不足。在介绍OmniVision公司的CMOS图像传感器中的SCCB总线的规范及总线构成和数据传输形式特点后,并针对低成本、低功耗的要求以基于ARM 7内核的三星公司的S3C44B0X平台上利用通用I/O接口与CMOS图像传感器OV7660芯片为例,说明了SCCB总线在嵌入式系统中的软硬件设计实现方法。With development of the image acquisition technique,CMOS image sensor is applying more and more widely. But the most MCUs have no SCCB bus interface, it offers some insufficiency. This paper introduces the specification of the OmniVision CMOS image sensor＇s SCCB and the data form in the bus firstly. It expounds a realization of hardware and software of SCCB by the application which expands I/O port in S3C44B0 embedded system and OV7660 chip in the low cost,low energy request,it has got better effect in the practice application.
