In this paper, the authors discuss about the stream of embedded system which can be defined as is a combination of computer circuitry and software that is built into a product for purposes such as control, monitoring and communication without human intervention. This paper discuss about the implementation of a CMOS camera (OV5647) sensor with MIPI CSI on ARM processor in considered using Linux environment can be used to take high definition video, as well as stills photographs. In this paper, the hardware structure, device driver design, key program implementation & transplantation are described in detail with the MIPI CSI & V4L2 structure on the ARM processor (BCM2835) embedded platform are emphasized.
