ITE高清晰度电视系统圆形区域测试图简介
1、1035TV的上水平边缘空间频率数量是与ITU-R709标准规定的有限扫描相同的。
2、空格次数的上垂直边缘的数目1840TV由高视力的长宽比16：9计算得来。
3、很容易地找到在一定区域内的空间频率的数量，每个阵列400TV在框外显示。

1.1035TV of space frequency on horizontal edges is the same number of effective scanning lines as ITU-R709 standard.
2.The number of space frequency on vertical edges is 1840TV calculated by aspect ratio of High-vision, 16:9.
3.To find the number of space frequency easily in a certain area, a display of 400TV each is indicated outside of the frame.
