英文摘要：

To solve the low image contrast and traditional histogram equalization algorithm for the problem of slow processing speed, an improved histogram equalization algorithm and FPGA implementation system is designed. The image enhancement is improved based on the algorithm, and the improved algorithm implements FPGA video processing platform realization hardware, experimental results show that this improved algorithm can produce clearer images, and image details of the processed image are well preserved, reach the purpose of image enhancement while simplifying the structure and design complexity of the system, save 35% of hardware costs and meet currently standard image for the real-time requirement and high lighted. The algorithm meets the real-time image processing requirements.
