Design of embeded image data processing system

Aim at the detecting one-dimensional bar-code in nowdays of real - time need, designing a low cost and moderate function image processing system. The acquisition and processing of image are the key components of the system. The system uses S3C2440, which installs Linux, as the core with circuit realize image processing function, multi - communication interface constitute image transmission channels. It is used as the central processing unit that is responsible for collecting, graying, filtering, thresholding the image and bar-code recognition, to connect a variety of interface logic match through the serial port and with a large memory for image storage. Experiments show that the system not only can meet the fast processing, but also meet the requirements of small and portable.
