The acquisition and processing of real-time images is the core technology in image acquisition system. Image acquisition is the basis of image processing, image compression, and image recognition. The speed and quality of image acquisition affect the performance of the overall system directly. Therefore, the study of the image acquisition system has very important practical significance and broad prospects. This project achieves the high-speed image acquisition and processing of high-speed images by a USB camera, The images are processed and stored using the clarity contrast function and histogram equalization function of image, and a series of theoretical and experimental verification and analysis are carried out, and the final results of the experiment are given.
