詳細(xì)介紹
1.1035TV of space frequency on horizontal edges is the same number of effective scanning lines as ITU-R709 standard.
1.這張圖上水平邊緣空間頻率為1035TV與 ITU-R709標(biāo)準(zhǔn)相同。
2.The number of space frequency on vertical edges is 1840TV calculated by aspect ratio of High-vision, 16:9.
2.這張圖的垂直邊緣空間頻率為1840TV可以計(jì)算比例為16:9的高視野寬屏。
3. To find the number of space frequency easily in a certain area, a display of 400TV each is indicated outside of the frame.
3.在特定的空間區(qū)域內(nèi)很容易找到對(duì)應(yīng)的空間頻率,但是在框架之外的每一個(gè)區(qū)域都顯示400TV。
4. This chart is only available for transparent type.
4.此圖僅適用于透明型。
