1、1035TV的上水平邊緣空間頻率數(shù)量是與ITU-R709標(biāo)準(zhǔn)規(guī)定的有限掃描相同的。
2、空格次數(shù)的上垂直邊緣的數(shù)目1840TV由高視力的長寬比16：9計(jì)算得來。
3、很容易地找到在一定區(qū)域內(nèi)的空間頻率的數(shù)量，每個(gè)陣列400TV在框外顯示。

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.
This chart is only available for transparent type.
