摘　　要：提出了一种基于帧间编码的实时图像处理系统,该系统在充分利用Ⅰ帧(参考帧)信息的基础上,设计了硬件基本结构,对系统的硬件电路设计、处理算法及时间等关键问题进行了讨论,以非线性图像拉伸处理算法为例分析了算法的实现过程和系统的实时性能,并对图像实时处理系统进行了分析和验证。该系统可满足当前的远程监控、电视电话、会议电视等诸多视频质量调整与传输领域应用的需求。A new image processing system is proposed based on inter-frame coding, On the basis of sufficiently using the Ⅰ- frame （reference frame）, the basic hardware architecture is designed, and the key issues such as selection of hardware resource, working routine, algorithm processing time and etc. are discussed in detail, Taking simple real time image processing arithmetic as an example, the feasibility of the prediction algorithm and the real time performance of the system are analyzed. The arithmetic is analyzed and validated in real time image processing system using DSP/CPLD. The system can fulfill the demands in many video/ image processing and transmitting fields such as the current remote monitoring and control, video telephone, video conference, road traffic control and etc
