摘　　要：以Exynos4412为处理平台,设计了以MIPI差分接口摄像头为采集端的高清系统硬件,进行了MIPI接口和DVP接口信号完整性仿真,设计了Linux下摄像头驱动程序,给出了软件架构的UML图。通过硬、软件调试和实验验证,成功实现Linux系统下的高清摄像系统。摄像头前端采集采用MIPI接口后,性能可达720p/60fps,相比于传统DVP接口摄像头,不仅传输帧率提高1倍以上,而且运行稳定,信噪比大幅度提高。Using Exynos4412 as the processing platform,the high definition system hardware based on MIPI differential interface camera is designed.The signal integrity simulation of the MIPI interface and DVP interface is carried out.The Linux MIPI camera driver is designed,and the software architecture of UML is given.The experiment results prove that the HD camera system under the Linux is successfully realized.The system performance is up to 720p/60 fps using the MIPI interface.Compared with the traditional DVP camera interface,not only the transmission frame rate increases more than one time,but alsothe signal-to-noise ratio is greatly improved and the system is stable.
