摘要
文中首先对两种媒体的成像性能作了定性比较，然后就ＨＤＴＶ电视摄像机的对比度处理与视频动态范围作了定量分析，给出了二者的对比曲线。比较结果表明，ＨＤＴＶ摄像机的有效动态范围高于３５ｍｍ胶片。从而扩大了ＨＤＴＶ摄像机的应用领域。
In this paper is discussed first imaging performance of both medium. Then are analysed contrast handling and video dynamic range of HDTV CCD camera. Figure 2 in this paper reproduces the effective dynamic range of the HDTV CCD camera and film. The comparison shows that the effective dynamic range of the HDTV CCD Camera is wider than that of 35mm film. So that the application of HDTV camera is expanded.
