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。
A green phosphor display is generally used as the human eye is most sensitive to the color green in this wave length, which falls in the middle of the visible light spectrum.
一般使用黄磷绿色显示，因为肉眼对黄磷绿色这种波长最敏感，这种波长位于可见光光谱中间。
Most of the light created by marine organisms is blue-green in color. This is because blue light travels best in water, and because most marine organisms are sensitive to blue light.
海洋生物创造的光多为蓝绿色，这是因为一方面蓝光在水中传播的速度最快，另一方面大部分海洋生物都对蓝光比较敏感。
The film measuring point of print grain index should be made according to its light-sensitive characteristics, being the density corresponding to the 0.74 gray density of color paper when printing;
印片颗粒指数的测试点应根据彩色负片的感光特性确定，为正常扩印时对应正片0 .74中灰密度的负片密度点。
The film measuring point of print grain index should be made according to its light-sensitive characteristics, being the density corresponding to the 0.74 gray density of color paper when printing;
印片颗粒指数的测试点应根据彩色负片的感光特性确定，为正常扩印时对应正片0 .74中灰密度的负片密度点。
