Design and Simulation of Image Preprocessor Based on FPGA

With the continuous development of image processing technology, and with the development and application of ASIC, DSP and FPGA devices, image processing has acquired a number of new technology, and FPGA based image processing technology has become the development trend in the field of image processing. This paper gives a brief introduction of the digital image, and gives the FPGA design scheme of the algorithm of median filter, edge sharpening and gray level histogram, and also gives the design principle diagram and simulation results. The experiment results showed that in the image processing system, it is feasible to realize the fast algorithm through the hardware of the software, which can well achieve the established objectives and meet the requirements of real-time.
