Abstract: With the expansion of the scope and connotation on video surveillance applications,the development of video equipments becomes more and more complex and multi-functional.In this paper,the underlying device drivers of video capture and display,which provided the high-level API interface function for high-level application developers,were designed and implemented by using the mine video surveillance equipment based on DM6437.In addition,it was taken a good example with the method of design-driven development for the similar video processing.
