摘　　要：本文设计了一种分辨率可调(最高分辨率为1920×1080)的实时视频图像采集与显示系统。该系统硬件部分利用OmniVision公司生产的OV5640 CMOS图像传感器采集视频数据,以Xilinx公司Artix 7系列FPGA芯片作为主控芯片,以一块Micron公司128 Mbit容量的DDR3 SDRAM作为缓存介质,以一块带有HDMI接口的显示屏作为图像显示屏。代码部分通过编写Verilog代码实现视频图像的采集、DDR3 SDRAM的读写缓存、HDMI的接口驱动。经过测试,该系统能够实现图像的实时图像采集与显示。This paper designs a real-time video image acquisition and display system with adjustable resolution(the highest resolution is 1920×1080).The hardware part of the system uses the OV5640 CMOS image sensor produced by OmniVision to collect video data,uses Xilinx's Artix 7 series FPGA chip as the main control chip,uses a Micron company's 128 Mbit capacity DDR3 SDRAM as the cache medium,and uses a piece with HDMI interface.The dis-play screen is used as the image display.The code part realizes video image acquisition,DDR3 SDRAM read and write cache,and HDMI interface driver by writing Verilog code.After testing,the system can realize real-time image acquisition and display of images.
