Abstract: An HD camera driver is designed based on the DM6467T chip hardware platform with VPIF interface for high definition video monitoring with support for raw format.This paper analyzes the V4L2 drive structure and designs the V4L2 core driver,VPIF interface driver and sensor driven.The program for testing driver is written,and the experimental result shows that the image data in raw format can be collected successfully.
