| 摘 要： | 研究分析了网络视频系统的基本原理和视频压缩方法,着重介绍了CCD成像原理和色彩还原的基本技术和方法,论述了JPEG压缩算法对彩色和灰度图像压缩不同,最后,提出了一种新型的基于CCD原始数据的网络视频压缩方案。并通过仿真将之与通常压缩方法进行比较,在传送同样质量的图像时,带宽减小1/3。

| Abstract: | The basic principle of present network video system and video compression methods is analyzed.The present charge coupled device(CCD) image formation principle and the color reversion technology and methods is introduced emphatically.The differences of compressing the color image and the gray image by JPEG compression algorithm is elaborated.Finally a new network video compression scheme based CCD primary data is proposed.Comparing with the usual compression scheme by simulating,when transmitting similar quality image,the bandwidth decreues one thirds. |
