从摄影系统采集的数据看，本次实验的影像质量较高，田块边界比较清晰，每组影像的亮度、景深等都有所差异。
The digital image got from the remotely-controlled helicopter was quite well, the boundary between different fields was clear and the variety of light was obvious.
其二是真实焊点影像的特征萃取与分类，论文中所提出之特征组是由影像区域分割与影像区域平均亮度两类所组合而成。
The second stage is the feature extraction from real solder images under the designed illumination, and the feature set proposed includes the partitioned regions and weighted areas.
专家说，这种新兴的显示媒体具有亮度高、动态影像显示效果好、故障低、显示内容多、显示方式丰富等特点。
Experts said that this emerging display medium features high illumination, remarkable dynamic video effects, good reliability, greater coverage of content, a rich range of display options and so on.
同时又利用MODIS影像的第1通道和第2通道的亮度值计算出该区域的NDVI值，并将其转化为植被盖度。
At the same time we use the brightness of MODIS band1 and band2 to calculate NDVI of this area, and translate it into coverage of vegetation.
在大屏幕投影显示领域，光引擎技术是获得大亮度、高影像清晰度和真实的色彩还原性图像输出的关键技术。
The technique of optical engine is the key to obtain high brightness, high definition and real colour pictures in the field of large screen projection.
除了提供更为一致的亮度，全阵列led背光能使屏幕上那些影像需要变暗的地方选择性的暗下来。
Apart from giving more uniform brightness, a full array of LED backlights allows the screen to be dimmed selectively in places where a scene needs to be dark.
