镜头

A dioptre is 1 divided by the focal length of the lens in centimetres. So a 1-dioptre lens has a focal length of 1m; a 2-dioptre lens has a focal length of 50cm; a 5D lens has a focal length of 20cm.

一屈光度是1除以该镜头焦距在厘米，所以一屈光度镜头焦距一米； 2屈光度镜头焦距50厘米； 1日5日镜头焦距二○厘米）。

After the sound enters the movie the space and time structure, strengthened in the lens space and time relations, has enriched in the lens spatial level and the implication, simultaneously has also enriched between the lens and the lens space and time relations.

声音进入电影的时空结构后，加强了镜头内的时空关系，丰富了镜头内的空间层次和涵义，同时也丰富了镜头与镜头之间的时空关系。

The article focuses on Flash animation for the solution to problems, from a technical point of view can not be over-reliance on Flash, should make use of other technology-rich Flash animation of visual expression; to improve modeling capabilities, in shape not only the pursuit of "alternative" style ; grasp the movement of animation can not be over-reliance on Flash for several deformation, so monotonous movements, stiff; master the basic knowledge of lens design, the lens forms, master lens fluid connection method, grasp the lens space and time in order to improve Narrative, performance capacity.

文章重点探讨了针对Flash动画所存在问题的解决途径，从技术角度上不能过分依赖Flash，应该借助其它技术丰富Flash动画的视觉表现力；提高造型能力，在造型上不能仅仅追求"另类"的风格；把握动画运动规律，不能过分依赖Flash所提供的几种变形形式，使动作单调、生硬；掌握镜头设计基础知识，镜头表现形式，掌握镜头联接流畅的方法，把握镜头的空间与时间，以提高叙事、表现能力。

In order to improve performance of uncooled thermal imager, diffractive optical elements are applied in high relative aperture IR lenses.

将衍射光学元件应用于非制冷热像仪的大相对孔径红外镜头与传统设计相比，衍射光学元件的引入，增强了此类镜头的色差校正能力，提高了镜头的成像质量，提高了镜头的透过率，减少了光学零件的数量，减轻了系统重量，为提高非制冷热像仪的性能奠定了坚实基础。

Telocentric lenses work with a wide depth of field. With a telocentric lens, you can image objects of different distances from the lens and the objects stay in focus.

具端着丝粒的镜头(注：我猜是类似于针孔镜头吧)具有宽阔之景深，以具端着丝粒的镜头，你能够将由镜头不同距离之目标物成像和保持目标物在焦。

In this framework, image frame, audio and text are represented, which are the three modalities in video shots as data points by the 3rd-order tensor. Then a subspace embedding and dimension reduction method is proposed, which explicitly considers the manifold structure of the tensor space from temporal-sequenced associated co-occurring multimodal media data in video. It is called TensorShot approach. Transductive learning uses a large amount of unlabeled data together with the labeled data to build better classifiers. A transductive support tensor machines algorithm is proposed to train effective classifier. This algorithm preserves the intrinsic structure of the submanifold where tensorshots are sampled, and is also able to map out-of-sample data points directly. Moreover, the utilization of unlabeled data improves classification ability.

在此框架中，视频镜头首先被表示成由视频中所包含的文本、视觉和听觉等多模态数据构成的三阶张量；其次，基于此三阶张量表达及视频的时序关联共生特性设计了一种子空间嵌入降维方法，称为张量镜头；由于直推式学习从已知样本出发能对特定的未知样本进行学习和识别，最后在这个框架中提出了一种基于张量镜头的直推式支持张量机算法，它不仅保持了张量镜头所在的流形空间的本征结构，而且能够将训练集合外数据直接映射到流形子空间，同时充分利用未标记样本改善分类器的学习性能。

When Griffis eagerly anticipates the narrative montage after Hollywood the mainstream, the Chaplin accident in is also emphasizing the single lens' expressive force, although he has also utilized some similar "Modern Time" begins the sheep and worker's two lens such performance montage technique, but more time he in faithful with panoram lens performance movement experience time,"Modern Time" mid summer Luo river the scene which sings in the dining room, the fixed positive panoram angle of view, the similar play's onlooking way, the audience can only see Xia the Luo one-man show, can obtain in merely the dining room from lens' laughter people's response,This is certainly for the more comprehensive clear performance its comedy movement and the scene, but actually unavoidably has "adheres to traitors" suspicion of the stage show.

当格里菲斯在好莱坞引领起叙事蒙太奇的主流之后，卓别林意外的还在强调著单个镜头的表现力，虽然他也运用了一些类似《摩登时代》开头绵羊和工人的两个镜头那样的表现蒙太奇手法，但更多的时候他还是在忠实的用全景镜头表现动作的经验时间，《摩登时代》中夏洛尔在餐厅中唱歌的场面，固定的正面全景视角，类似戏剧的观看方式，观众只能看到夏尔洛的独角戏，仅仅能从镜头之外的笑声中得到餐厅里人们的反应，这当然是为了更全面清楚的表现其喜剧动作和场景，但却难免有&附逆&舞台表演之嫌。

Its theoretical foundation is Dempster-Shafer evidence combination theory, which can fuse the evidence from distinct views and cooperatively infer the most likely relevant results, If the evidence from multiple aspects reaches a consensus on the conclusion that a certain video shot is relevant to query, the video shot is treated as the most likely relevant shot and is ranked to the top of the returned result list.

该方法利用Dempster-Shafer证据推理理论来协同地融合多方证据，进而推断出最相关的视频镜头。如果多方证据一致，则证明某个视频镜头是相关的，此镜头被认为是最相关的镜头，并被排在返回列表的最前列。

The 135mm DC is Nikon's best hand-held portrait lens ever, as well as a killer-sharp 135mm lens for everything.

该镜头135mm DC是尼康最好的手持拍摄的镜头不断，以及杀手锋利的一切镜头135mm镜头。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
