brightness ratio

基本解釋

Regardless of this fact, there is need to optimize all general specifications, such as brightness, contrast ratio, color gamut, and so on.
即使這樣，包括亮度、對比度、彩色色域等所有常見的規(guī)格都需要優(yōu)化。
In view of the incompleteness of the condition in testing image intensifiers output signal-to-noise ratio, the brightness gains effect on output signal-to-noise ratio is expounded.
亮度增益和等效背景照度是衡量像增強器性能的兩個重要參數(shù) ，針對這兩個參數(shù)的測試要求，闡述像增強器亮度增益和等效背景的測試原理和測試儀的結構設計。
Its advantages are discarding thick and heavy cover glass, high utilization ratio of energy, high brightness of refraction image, easy to making plane frame of hologram for display and easy to carry.
該法優(yōu)點是不需要厚重玻璃襯板，光能利用率高，重現(xiàn)像亮，易于把全息圖制成平面一體化構架，便于攜帶。

Interestingly, HP won't discuss the other specs in great detail, except to say that the contrast ratio and brightness levels are comparable to most notebook screens.
