ITE高清晰度電視系統(tǒng)圓形區(qū)域測試圖簡介

1、1035TV的上水平邊緣空間頻率數(shù)量是與ITU-R709標準規(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.
