The embedded system is the computer system which is application-centric, has the characteristics of better cutting for software and hardware, adapting to application system. Strong specificity is the most significant characteristics. Embedded system is designed for customer, product and application. The development process and how to use the camera interface, based on the S3C6410 processor with the ARM11 core, was introduced in this paper. The problem of the 500W pixel image in original driver programmed by Samsung was solved successfully and the development method of the stream interface driver on the WinCE embedded operating system was well presented.
