简单粗暴:非编软件里生成SMPTE测试图,用媒体播放器看一遍。因为你只要测亮度,只用看右下角三条黑柱子,从左到右:超级黑、黑、灰。看到三条是有问题的,只能看到灰色就是正确的。
1.Turn on the monitor and allow it to warm up (10-15 minutes).
2.Using a guaranteed source, display SMPTE color bars on monitor.
3.Turn the monitor's chroma off or down completely.
4.The pluge pattern consists of the three dark bars at the lower right - superblack, black, and gray. Adjust the monitor brightness until there is no discernable difference between superblack and black, but there is a difference between black and gray.
5.Adjust the monitor contrast until a smooth gradient of gray appears along the top bars.
6.Turn the red and green guns off (there may be a "Blue gun only" option to achieve this). If your monitor cannot do this, look at the bars through a blue filter.
7.Turn the monitor chroma up until the far left bar (white) and far right bar (blue) have the same brightness.
8.Adjust the monitor tint (hue or chroma/colour phase) until the third bar from the left (cyan) and the third bar from the right (magenta) have the same brightness. |
