镜头组

该模型可以从帧、镜头、镜头组、场景、故事单元等不同层次对视频的结构进行描述。

In our model , videos are represented in a hierarchical structure with five layers from frame , shot , shot group , scene to story unit , and key frames , etc.

中文摘要本文主要讨论了直线感应加速器束流诊断系统的OTR镜头组的设计和研制工作。

The design and research of OTR lens for Beam diagnosing system of LIA were introduced in this paper .

基于应用光学理论，设计物镜镜头组，柯拉照明系统，并对镜头组的变焦距拆分、扫描法等作了研究。

Object lenses and kohler illumination system are designed based on application optics theory . Splitting and linking of zoom lens , scan system is studied .

六个至八个镜头一组，这个数字大致符合吗？

Six to eight lenses to the set ; would that be about the number ?

电影依靠一个个镜头的组接来叙事，也可以说是靠运动着的造型（影像和声音）和话语（有声语言和字幕）的有机构成来叙事。

Film relies on a group access to a narrative lens , it can be said to rely on the shape in motion ( video and sound ) and words ( with sound language and subtitles ) of the organic composition to narrative .

他们先是拍了小男孩怎样拿到车匙，接着为了拍下更多让观众信服的镜头，摄制组把小男孩放到驾驶座上。

They first filmed the boy taking the keys , then put him into the driver 's seat again for more authentic pictures .

经证实，这组照片并非伪造。当时米德尔顿和她的丈夫威廉王子正在法国南部度假享受日光浴，显然有人用长焦镜头偷拍到这组照片。

It has been confirmed that the images are genuine , taken apparently with a telephoto lens while Middleton and her husband , Prince William , were sunbathing on vacation in southern France .

功率计镜头含有会聚物镜组加中性滤光片的光学系统以及光电转换器件；功率计电子箱由光电转换电路、跟随电路、时序控制电路、积分电路、A／D转换电路、显示电路等组成。

The lens of the power-tester is composed of a optical system of gather and filter , a photoelectrical converting circuit , a following circuit , sequence control circuit , integrating circuit , A / D converting circuit and displaying circuit .

该BESSA三是高便携式，折叠伸缩镜头，让极高质量的图像将要采取使用一个高性能的镜头组。

The BESSA IIIis a high portable , folding bellows camera that allows extremely high-quality images to be taken using a high-performance lens unit .

根据望远镜的工作原理，对变焦距光学镜头的变焦运动进行了定性分析，并且根据理想光学系统的物像关系式推导出该镜头运动镜组的运动方程。

The zooming movement of zoom optical lens is qualitatively analyzed according to operating principle of telescope . The movement equation for the lens moving lens set is derived according to the object-image relationship of the ideal optical system .
