闪光灯

Since many cameras use this as the default setting, you may be using the flash without knowing it.

这是因为许多相机使用的设定违约，你不知道它是用闪光灯。

Keep in mind that the intended result is to have no discernable flash shadow.

并且要时刻铭记不能在照片上留下闪光灯造成的阴影。

It's no big deal since my DS is flashed but it might be for others.

这没有什么大不了，是因为我的感想，但可能是别人的闪光灯闪。

The last stop of the world preview at London, Empire Cinema, has attracted over 100 media from all over the world, which includes BBC, London Tonight, etc. On the day of the London premiere of Speed Racer, Rain has been well-received by all media and fans from around the world.

举行巡回试映会最后行程的英国伦敦Empire Cinema里，吸引了世界各地的如BBC，London Tonight等100多个的媒体参加，这天，Rain并受到了从世界各地前来的媒体和粉丝的闪光灯洗礼。

The other attributes of the Bold 9700 are like the BlackBerry Curve 8900 and Tour: They all have cameras with flashes that are capable of capturing 3.2-megapixel photographs, bright 480x360-pixel displays, built-in GPS and slots for microSD memory cards so as to expand their memory.

Bold 9700的其他一些特性跟Curve 8900和Tour一样，它们都有内置闪光灯的照相功能，可拍320万像素的照片，拥有明亮的480×360像素显示屏、内置GPS，还有microSD扩展记忆卡插槽。

Meter the scene, select an f-stop, set the autoflash aperture to the same f-stop, and shoot.

根据场景选择合适的光圈，将闪光灯的光圈设置为同样大小。

This exposure is made with a small F-stop to a sheet of white paper placed over the original, or to the rays from a flash- lamp.

闪光曝光，可用小光圈档，用一张白纸放在原稿上面或用闪光灯曝光。

It is the first important step in video analysis and will directly affects the effectiveness of indexing Shot boundary detection is one of our major research interests and we will tackle the following existing problems the ambiguity between gradual change and camera motion, the discontinuity during gradual change, false detection caused by illumination variation and flashlight, automatic threshold selection Firstly, we discuss shot boundary detection in non-compressed domain In chapter 2, we compare some of the commonly used detection methods which are based on frame difference and point out that single feature will not generate good results As a conclusion, we use fuzzy logic to combine multiple features Presently, most frame difference based shot boundary detection algorithms rely on threshold and hence the selection of such thresholds will greatly affect the performance of boundary detection We propose a membership function to define frame difference and calculate the membership with self adaptation according to the statistic distribution of frame differences to satisfy different type of video clips Experiments show that the proposed fuzzy shot boundary detection algorithm can be used with different video types and has a high detection precision and recall In chapter 3, we discuss model-based shot boundary detection algorithms regarding chromatic and spatial editing effects such as fade-in, fade-out, dissolve and wipe Various parameters are proposed to better describe the characteristics of each editing type.

镜头边界的检测是把视频自动地分割为一个个镜头，作为基本的索引单元，因此它是视频分析重要的第一步，直接影响到视频检索的成败。镜头边界的检测是本文研究的重点之一。目前镜头边界检测算法主要存在以下问题：渐变与镜头运动难以区别；渐变过程中的不连续与停顿、光照条件的变化及闪光灯等特殊情况会引起误检测；自动选择阈值比较困难等。本文首先针对非压缩域视频进行了镜头边界检测的研究。在第二章中我们采用了比较流行的基于帧间差的方法。在比较各种帧间差计算方法的基础上，指出使用单一的特征难以取得很好的检测效果，提出用模糊逻辑综合使用各种特征。目前大多数基于帧间差的镜头边界检测算法都采用阈值法进行镜头转换的判别。阈值选择的误差对检测性能有较大的影响，本文提出用隶属度函数定义帧间差较大、中等较大和较小等概念，并根据帧间差的统计分布自适应地确定隶属度，以适应不同类型的视频片断。实验结果表明这种基于糊逻辑的镜头边界检测算法可以适应不同的视频，并具有较高的检测精度和检出率。在第三章中采用基于模型的方法进行镜头渐变的检测，研究了淡入／淡出、慢转换和扫换的模型。

Without a strobe light to animate its riot of colors, this Fijian reef in 45 feet (14 meters) of water remains as a fish would see it.

没有用闪光灯使它的闹事的色彩有生气，这个斐济的暗礁45英尺（14米）的水域继续存在像鱼类会看见它。

I believe they were originally used to pulse a flash lamp in an airport.

我相信它们最初是用来为机场的闪光灯供电的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
