目的设计并研制一种基于ＪＰＥＧ标准的组合型实时（准实时）图像编码压缩处理系统．方法分开研制数字图像采集子系统和图像编码压缩子系统，既可单独应用，也可联合工作，以逐帧完成对图像的实时（准实时）编、解码．两个子系统分别选用高性能数字解码芯片集、视频窗口控制器、ＣＬ５５０－ＪＰＥＧ标准图像编码专用处理器．结果系统性能良好，运行可靠．结论系统设计思想正确合理，具有较高的性能价格比．
Objective To design and develop a combined real-time (quasi-real-time) image coding and compression processing system based on JPEG standard. Methods The digital image acquisition subsystem and the image coding compression subsystem are separately developed. They can be used separately or jointly to complete the real-time (quasi-real-time) editing and decoding of the image frame by frame. Two subsystems were selected high-performance digital decoder chipset, video window controller, CL550-JPEG standard image encoding dedicated processor. Results System performance is good, reliable operation. Conclusion The system design philosophy is correct and reasonable, with a high cost performance.
