Abstract:

The paper aims to study a design and technique of the image processing based on the architecture of embedded system. Aimed at the own characteristic of embedded system, designing a platform been endowed with more operating functions of embedded image processing with versatility. The author adopts the method of the embedded system design based on the basic functions and characteristic of image processing system, summarizing and comparing of the characteristic and new developments of the EOS for the ARM processor, and finally chooses the embedded Linux for the operating system of our platform, also transplant it in the hardware platform. Aimed at the characteristic of Linux device architecture, the author introduces how to develop the image capture and display, memory the data of an image, the programming method of that. Some base arithmetic of image processing, such as image smooth, sharpen, edge detect and so on, and the graphics user interface are developed on the platform with using the Mini GUI, according to the intercommunion between the human and the platform. At last, some key program's code is given.
