Research Of Image Capture And Processing System Based On ARM

Traditional image processing system based on PC is large and non-portable which restrict the application in the field such as mobile communications, portable devices and so on. Developing a low power, small size, portability of embedded image processing system has practical significance and wide range of application prospects. This article analysis the function and designs the system, it selects the LPC2104 as core modules, introduces the design and realization of hardware platform, including design hardware and development process, has a power circuit and the clock circuit, the storage circuit, interface circuit of USB cameras and LCD circuits. Completed custom of Linux kernel, cross-compiler, BootLoader, and driver development. Implied the image pretreatment such as gray and equalization, got a clearer picture. In the end, the paper summarizes the results and the inadequacies of the subject, and prospects the research.
