At night, it's the extra-sensitive rods that take over — this is why it's difficult to detect color in low levels of light.

夜间，特别敏感的视杆细胞在眼睛视物占有主导地位—这就是为什么在昏暗的光线条件下我们很难看到事物的色彩。

Spitzer's liquid helium coolant ran out in May 2009, so this false color view is from two channels that still remain sensitive to infrared light at warmer operating temperatures.

斯皮策的液态氦冷却剂在2009年5月用完了，所以这张假彩色图像来自在目前较温暖的操作温度下对红外光仍然敏感的两个波道。

The HSI color model is not sensitive to light, so we can use it for color calibration, image segmentation by run-length code, and objection recognition to the ball, goal, and the white lines.

对于由全景视觉系统采集到的全景图像，本文采用对光线不敏感的HSI颜色模型进行颜色标定，利用游程编码进行图像分割，并在此基础上进行球、球门、角柱和白线的特征提取。

It is an interesting triple "coincidence, " which probably evolved over time, that our eyes are most sensitive to yellow-green light, which happens to be the characteristic color of sunlight as well as the color that can most easily be transmitted through the Earth's atmosphere.
