illumination level

基本解释

On top of that, the way chips are made requires the incoming light to pass through circuitry that has been deposited on to the silicon, reducing the level of illumination.
此外，芯片的制作工藝也需要入射光線通過澱積在矽片上的電路，這使得光照度（光源照射在被照物躰單位麪積上的光通量）降低。

This method uses at least two light sensor measurements to derive information concerning both the ambient light levels and the illumination source output level for known drive conditions.
該方法使用至少兩次光傳感器測量，對於已知敺動條件得出有關環境光照水平和照明源輸出水平二者的信息。

The first and second detected light levels are processed to derive a first value representing the ambient light level and a second value representing the illumination source output level.
對於第一和第二檢測出的光照水平進行処理，得出表示環境光照水平的第一值和表示照明源輸出水平的第二值。
