前言现代电视技术发展水平的特点,是对设备的质量指标的要求不断增加。当研制电视设备(电视机、视频控制和观测装置和其它装置)时,人们特别注意获得再现的电视影象和其原始影象的高度几何相似。除校正几何失真外,研究人员努力设法将影象的水平和垂直非线性失真减至最小。影象的最小非线性失真的特点是在扫描 Preface The characteristics of the development of modern television technology is the increasing demand for quality indicators of the equipment. When developing television equipment (televisions, video control and observation devices and other devices), special attention has been paid to the geometrical similarity between the height of the reproduced television image and its original image. In addition to correcting for geometric distortions, the researchers worked hard to try to minimize the horizontal and vertical nonlinear distortion of the image. The smallest nonlinear distortion of the image is characterized by scanning
