Tracing the Way of Data in a TCP Connection through the Linux Kernel

With the processing of CMOS technology, the technology of video acquisition based on CMOS is becoming a new trend. However, many CMOS camera chip is not supported by the newest Linux kernel yet. The environmented image acquirement and the bluetooth transmission system are studied and designed . In this paper, the method of designing the CMOS camera driver based on S3C2440 developing board with the embedded Linux environment is introduced and add some components such as a usb bluetooth adapter. SCCB is a distinguishing feature of OV series CMOS chips. S3C2440 provides a camera interface, and the camera driver is designed based on it. The library and the utils are compiled, and of images got from CMOS camera to the Bluetooth mobile phone has been realized by means of programming
