一引言人的视觉器官,决定了电视图象所在平面的形状,应是宽高比近似为4:3的矩形。欲用电子束扫遍整个矩形面积,可以有各种顺序。现行的扫描方式(由左至右形成水平的行扫描线,把行扫描线由上至下地排列,完成对矩形面积的扫描)虽毫无例外地用于世界各国的电视系统,但并非最佳选择。这种扫描方式的设计,很可能是由于电视发明人的书。写习惯所
I. INTRODUCTION Human visual organs determine the shape of the plane in which a television image is located. It should be a rectangle with an approximate aspect ratio of 4: 3. To scan the entire rectangular area with an electron beam, there are various sequences. The current scanning methods (horizontal scanning lines from left to right and line scanning lines arranged from top to bottom to complete the scanning of the rectangular area) are used in television systems of all countries in the world, but are not the best select. The design of this scanning method is probably due to the TV inventor’s book. Write habits
