摘　　要：基于图像采集的高速性、实时性和方便性的要求,设计了包括两种模式的图像采集存储系统:联机系统和脱机系统。设计中选用性价比优异的视频信号编解码芯片SAA7114H和SAA7121H,同时采用高可靠性、低功耗的CY7C68013A芯片作为核心控制器,采用Altera公司的Cyclone TM系列的EP1C6Q240C8的FPGA (现场可编程门阵列)芯片来处理图像信号,从而保证了高速的图像采集、图像处理、硬盘存储、图像监视和图像回放功能的实现,经验证可行。In view of the requirements of high - speed, real - time and convenient image sampling - mode image sampling and storage system is designed, namely the on - line and off - line system. Low , atwo in cost and high in performance, SAA7114H and SAA7121H are selected as the video signal coding and decoding chip; the high- reliability, low- power muhiprocessor chip CY7C68013A is used as the core controller; and Altera~ Cyclone TM series EP1 C6Q240C8 FPGA （Field Programmable Gate Array） chips are adopted to handle video signals, thereby ensuring the realization of system image sampling, image processing, disk storage, surveillance images, image playback. Its feasibility is validated .
