The embedded technology was becoming more and more popular in various fields. Thus, embedded vision system based on ARM9 and Linux was proposed. It has expounded hareware structure and software composing. The image gather and display’s program were written with B4L interface functions by configging and loading kinds of device drivers. The embedded vision system designed has some characteristics such as little volume, low cost and better transplant. The experiment wave and data show it has better performance of image gather and display.
