Scientists at Duke University in North Carolina have built an experimental camera with more than 30 times the data-collecting capacity of today#39;s best consumer digital devices, a development that could fundamentally alter the way images are captured and viewed. 美国北卡罗来纳州杜克大学(Duke University)的科学家制造出了一台数据采集容量为当今最先进的消费型数码相机30多倍的实验性相机,这一成果可能会彻底改变人们拍摄和观看图片的方式。 While today#39;s best digital cameras take images having pixel counts in the tens of millions, the latest device produces a still or image with a billion pixels, which is five times more detail than can be seen by a person with 20/20 vision. A pixel is one of the many tiny areas of illumination on a display screen from which an image is composed. The greater the number of pixels, the more detailed the image. 现今最好的数码相机可拍摄分辨率达数千万像素的图片,这款最新的相机能够拍摄10亿级像素的静态图片或视频图像,而且清晰度比完美视力的人眼所能看到的图像要清晰五倍。像素是显示屏上所显示的一个个小方点,它们排列在一起就构成了影像。其他条件相同的情况下,像素数越高拍出来的图片就越清晰。 The experimental Duke device, known as AWARE-2, is a long way from being a commercial product. The current version needs lots of space to house and cool its electronic control boards; it weighs 100 pounds and is about the size of two microwave ovens stacked together. It also takes about 18 seconds to shoot a frame and record the data on a disk. 杜克大学研发的这款实验性相机名为“AWARE-2”,其要实现商业化生产还需很长一段时间。当前这个机型需要很大空间来存放和冷却其电子控制面板。它的重量达100磅(约45公斤),体积约相当于两台微波炉叠在一起。用它来拍摄图片并把数据存在磁盘上需要18秒左右。 The availability of a hand-held gigapixel camera could spark an alternative approach to photography. Instead of deciding where to focus a camera, a user would simply shoot a scene, then later zoom into any part of the picture and view it in extraordinary detail. Desirable or useful portions could thus be identified or #39;mined#39; after the images are captured. 手持式10亿像素级相机的问世可能会引发另一种摄影方式的产生。摄影者不必决定把焦点对准何处,只需把画面拍下来,将图片的任一部分放大即可极其细致地观看它们。在拍完图片之后,摄影者可把满意的或是有用的部分确定下来或者是“抽取”出来。 Taking a picture with a traditional digital camera ;is like looking through a soda straw since you can only see a narrow part of the scene,; said David Brady, optical engineer at Duke University, who led the team that designed the one-gigapixel camera. ;Ours is more like a fire hose-the world comes at you full [blast];. 杜克大学光学工程师戴维#8226;布拉迪(David Brady)说,用传统数码相机拍照就像通过一根苏打水吸管看东西,因为你只能看到一小块画面,而他们的新型相机则更像从消防软管看东西,整个世界完全展现在你的眼前。 Dr. Brady said that when his team used the device to take a photograph of the Seattle skyline, they were able to zoom in and the ;In; and ;Out; signs written on a parking garage located half a mile away. Similarly, if the camera were used to take images of a tennis match, the viewer could zoom in on a player, or on someone at the far end of the stadium, and see both images in equal detail. 布拉迪是这台10亿像素相机研发团队的领头人,他说其团队在用它来拍摄西雅图天际线的图片时,能够把图片放大看到半英里之外一个停车库上写着的“入口”和“出口”标识。同样地,如果观众用这台相机来拍摄网球比赛的视频,也可以把选手或坐在球场远处另一端的观众的图像放大,看到的图像都同样清晰。 Details of the Duke camera were published Wednesday in the journal Nature. The million project is funded by the Defense Advanced Research Projects Agency, part of the U.S. Department of Defense. The military is interested in high-resolution cameras as tools for aerial or land-based surveillance. 有关这台相机的详细信息最近发表在了《自然》(Nature)杂志上。这个2500万美元的研究项目由美国国防部尖端研究项目局(Defense Advanced Research Project Agency)资助。美国军方有意将高分辨率相机用于航空及地面监控用途。 Many scientists believe the age of gigapixel photography isn#39;t too far away. 许多科学家都认为,10亿像素级摄影时代距离我们不会太遥远。 The Pan-STARRS telescope in Hawaii uses several gigapixel cameras, though it is designed for astronomical use. Some drones carry megapixel cameras, but they tend to have a relatively narrow field of view. The Gigapixl Project is using large-format film cameras to create a highly detailed coast-to-coast portrait of North America, focusing on cities, parks and monuments. 夏威夷“全景巡天望远镜与快速反应系统”(Pan-STARRS)的望远镜也使用了数个10亿像素级的相机,但它是用于天文用途的。一些无人机安有百万像素级的摄像头,但它们的视场角往往比较狭窄。10亿像素计划(The Gigapixl Project)正使用大画幅胶片相机拍摄高清晰度的北美全景照片,并把焦点放在城市、公园和纪念碑上。 By comparison, the Duke device the ;first cut at making gigapixel; cameras for general use, said Shree Nayar, a computer-vision researcher at Columbia University in New York, who has seen the camera work but wasn#39;t involved in the project. The challenge, he added, is to shrink the electronics and reduce the amount of power the system required. 纽约哥伦比亚大学(Columbia University)计算机视觉技术研究者希瑞#8226;纳亚尔(Shree Nayar)称,相比之下,杜克大学研发的相机是促进10亿像素级相机用于普通用途的首台设备。他还说,其中的困难在于如何缩小电路板空间并降低设备所需的电量。纳亚尔观看过这台相机的操作,但他并未参与该研究计划。 The secret of the Duke device is a spherical lens, a design first proposed in the late 19th century. Although very effective spherical lenses exist naturally lenses-the human eye, for example-researchers have long found it tricky to accurately focus images using lab-made versions. 杜克大学所研发的10亿像素相机的秘诀是一个球形镜头,该设计创意最初于19世纪晚期提出。尽管效果非常不错的球形镜头天然就存在(比如人眼),但是长期以来研究人员发现要想用实验性的机型精准对焦还是颇有难度。 The Duke group overcame the challenge by installing nearly 100 micro-cameras, each with a 14-megapixel sensor, on the outside of a small sphere about the size of a football. The set-up yields nearly 100 separate-but accurately focused-images. A computer connected to the sphere then stitches them together to create a composite whole. 杜克大学的研究团队克了这一困难,他们在一个足球大小的球形小镜头的外部安装了近100台微型相机,每台相机都配有一个1400万像素的传感器。这种配置可拍摄近100张独立而且对焦精准的图片,与球形镜头连接的计算机随后会把它们拼凑在一起合为一张完整的图片。 The camera described in the Nature paper only takes black-and-white pictures. Dr. Brady said his team will finish building a 10-gigapixel color version by year-end and will then construct a 50-gigapixel device. 发表于《自然》杂志的论文所描述的相机只能拍摄黑白照片。布拉迪士称其团队将于今年年底制成一台100亿像素的色相机,并计划在未来制造一台500亿像素的相机。 The team hopes to begin manufacturing industrial-type gigapixel cameras on a limited basis in 2013. But scientists estimate it will take at least several years before a hand-held consumer version of the technology becomes available.该团队希望在2013年开始对10亿像素相机进行小规模的量产,但是科学家们估计手持式消费型10亿像素级相机至少还需要数年时间才能面市。 /201207/189118The last time we wrote about Doug Kass -- a small hedge fund manager with a large presence on CN -- it was to document a neat little trick he played on his Twitter feed in February, the day before Apple#39;s annual shareholder meeting.我们上一次提到道格#8226;卡斯还是在今年 2 月,苹果年度股东大会的前一天。卡斯是一家小型对冲基金公司的经理,在美国全国广播公司财经频道(CN)颇有影响力。当时那篇文章提到了他在Twitter上玩的一个小把戏。Apple#39;s (AAPL) share price was down and Kass was long the stock. He tweeted a rumor that the company was about to announce a split, the stock went up, he sold his shares at a profit, tweeted that the rumor was baseless and then spent the rest of the day hurling insults at his critics. (See A day in the Twitter life of Doug Kass.)当时,苹果(Apple)股价下跌,而卡斯正在做多苹果股票。他在Twitter上发布传闻称,苹果即将宣布分拆。受此消息影响,苹果股价出现上涨,而卡斯在盈利之后便抛售了所持股票。他随后又发布消息称传闻并无依据,随后遭到了大量指责。(参阅道格#8226;卡斯在Twitter上的一天。)Well, Kass is at it again. On Sunday, citing the same ;Gnome; that was the source for his stock split story, he tweeted:如今,卡斯又故伎重施。他援引与其股票分割传闻为同一个消息来源的“Gnome”的说法称:Kass, it turns out, is not alone in suggesting that the solution to Apple#39;s woes on Wall Street is to fire its CEO. We#39;ve been hearing whispers to that effect from disgruntled shareholders for weeks, but now -- two days before Cook is scheduled to report Apple#39;s March quarterly earnings -- they#39;ve come to the surface.为了取悦华尔街,苹果应该炒掉库克,持这种观点者不仅仅只有卡斯一个人。数周以来,不满的股东们都在私下议论纷纷,大体意思都是要求库克下台。如今,距离苹果发布 2013 财年第二财季财报还有两天,这些不满情绪正在浮出水面。And who#39;s doing that? Let#39;s take a look:我们来看看放出这些风声的都是谁:We#39;ve got the tweet from Doug Kass, whose main Apple-related claim to fame was to publish his ;Bear Case for Apple; the day before the stock began a nosedive that lopped 0 billion off the market cap of the world#39;s most valuable company.我们已经知道了道格#8226;卡斯通过Twitter发布的消息。而真正使他备受关注的是在苹果公司股票暴跌,使这家全球最有价值公司市值缩水3亿之前,他所发表的《看跌苹果》一文。We#39;ve got The impossible task of fixing Apple by Rob Enderle, a consultant for Dell (DELL), Microsoft (MSFT), Hewlett-Packard (HPQ) and others, who has made a career of bad-mouthing Apple in print and on TV. (For background on Enderle, you can start with John Gruber#39;s 2003 Putting the #39;anal#39; in #39;analyst#39;.)知名科技行业顾问罗#8226;恩代尔撰写了一篇题为《修复苹果,不可能完成的任务》的文章。他是戴尔(Dell)、微软(Microsoft)和惠普(Hewlett-Packard)等公司的顾问,长期以来一直在纸媒和电视上唱空苹果。(关于恩代尔的背景资料,可从2003年约翰#8226;格鲁布的《堵住‘大嘴分析师’的嘴》一文开始查阅。)We#39;ve got Sunday#39;s Is Apple Looking For A Replacement For CEO Cook? in Forbes.com, the online arm of a once-respected business publication whose experiment in what it calls ;incentive-based, entrepreneurial journalism; has led to what Macworld calls ;a relentless clown show of anti-Apple contributors.;《福布斯》网站上周日刊登了一篇题为《苹果是否正在寻找 CEO 库克的接班人》的文章。作为一家商业期刊的网络版,这个网站一度倍受尊敬。不过这篇文章被 Macworld 杂志指责为“代表反苹果作者的小丑表演”。Make no mistake, the people who want Tim Cook#39;s head on a spike are not friends of Apple. As far as I know, he still has the deep respect of the analysts who know the company best and -- most important -- the confidence of the board of directors who granted a million restricted shares of Apple as an incentive for him to stick around for at least a decade.毫无疑问,希望库克下台的投资者并不是苹果的朋友。据我所知,了解苹果的分析师对库克仍然非常尊重。更重要的是,苹果董事会向库克提供了 100 万股受限股,作为吸引库克留在苹果的激励措施。它体现了董事会对库克的信心。For the record, Apple is still trading higher today than it was when Cook replaced Steve Jobs. The forces that drove the stock up to over 0 and then down to below 0 seem to me to have more to do with a dysfunctional securities market than anything Cook has done as CEO.目前,苹果股价仍高于库克接替乔布斯出任苹果 CEO 时的价格。我认为,苹果股价上涨至 700 多美元,随后回落至 390 美元,更多的是因为股票市场的机能失调,与库克担任 CEO没有什么关系。;The market is crying uncle and something has got to give,; says Oracle Investment#39;s Laurence Isaac Balter, who has been banging the ;Cook must go; drum for weeks.投资公司Oracle Investment 的劳伦斯#8226;艾萨克#8226;巴尔特过去几周中一直在鼓吹“库克必须离开苹果”。他说:“市场已经投降,必须有所作为。”;If a stock rally hits on this rumor before earnings it will be a sign for sure.;“如果在财报发布前股价受这一传闻刺激出现上涨,那么将是肯定的信号。”Now that#39;s rich.这可真够搞笑的。UPDATE: Rocco Pendola, who blows hot and cold on Apple, weighed in to say he#39;s been publicly lobbying for Cook#39;s ouster in his column on The Street since last Wednesday, including a piece Monday morning that called the decision to recommend Cook as CEO the worst decision Steve Jobs ever made.最新消息:对苹果的态度一直摇摆不定的知名投资人洛克#8226;彭多拉也在 The Street 网站的专栏上发布消息称,他从上周三开始一直在公开游说苹果驱逐库克。他在本周一的一篇文章中表示,选择库克作为 CEO 是乔布斯一生中最大的决策失误。 /201304/236758

Not necessarily into the brash, bullish, brute image generally associated with Lamborghinis?不那么喜欢通常与兰基尼汽车联系在一起的傲慢、自信和野兽般的形象?Then you’ll love the latest one. Consider if you please the new Hurácan LP 610-4, Lamborghini’s 610-horsepower carbon fiber coupe. Designed as the successor to the iconic Gallardo, it’s considerably more refined than previous offerings from the Italian brand with a fresh new look inspired by the excellent Aventador and refined in a new improved body made of carbon fiber and aluminum. (Translation: It’s lighter with better rigidity!)那么这款最新车型可能符合你的心意。请考虑兰基尼最新款610马力碳纤维双门硬顶跑车——Hurácan LP 610-4。作为典范车型Gallardo的继任者,它比该意大利品牌之前的产品更加讲究;灵感源于非同凡响的Aventador,采用全新外观;车身也得到改进,采用碳纤维和铝合金制造。Hurácan has a mid-mounted 5.2-liter V10 engine that pairs the aforementioned 610 horsepower with 413 pound-feet of torque over all four wheels. It also offers Lamborghini’s first-ever seven-speed, dual-clutch transmission. (Sorry boys, no manual drive available.)Hurácan搭载一个中置5.2升V10引擎,采用四轮驱动系统,最大功率610马力,最大扭矩413磅·英尺。该车还装备了兰基尼首个7速双离合变速箱(不好意思各位,这款车没有手动档版本)。All to say that this car will hit 62mph in 3.2 seconds and has a top speed of more than 200 mph.该车可以在3.2秒内从静止加速至62英里每小时,最高时速超过200英里每小时。Also on offer in the new whip: Standard carbon ceramic brakes, three drive modes and a stop-start technology that improves efficiency. Magnetic shocks and a variable steering system are optional.这款新车的配置还包括:标配碳陶刹车盘、三种驾驶模式以及启停技术(可以减少油耗)。磁流变避震悬挂控制系统以及一个可变传动比动态转向系统是可选配置。And lest you traditionalists wonder, this Lamborghini, too, is named after a famous fighting bull. The bull Huracán of the Spanish Conte de la Patilla breed was known for his outstanding courage and strong sense of attack. He fought in Alicante in August 1879 and according to Lamborghini records showed “unrelenting character” while remaining defiant and invincible, thus entering into the legend of fighting bulls’ history.为免各位传统派人士提出疑问,特意说明一下,这款兰基尼汽车同样以一头著名的斗牛的名字命名。拥有西班牙斗牛Conte de la Patilla血统的Huracán因其非凡的勇气以及强大的攻击意识闻名。根据兰基尼的记录,1879年8月这头斗牛在Alicante战斗时,展示出“永不屈的性格”并始终保持昂扬斗志,因而成为斗牛历史上的一个传奇。Private previews of the car start next month, but look for the live public debut next March at the Geneva Motor Show. I’m not typically the bullish type, but if Hurácan handles anything like its predecessor, we’ll get along just fine.该车的私人预览从下个月开始,不过它将在明年3月的日内瓦车展(Geneva Motor Show)上公开亮相。通常我不是那种爱持乐观看法的人,不过如果Hurácan可以达到其前任的表现,我们将会喜欢它的。 /201401/272498

Youku Tudou, China’s largest hosting website, announced the creation of its own film studio Thursday in a move to capture a larger slice of the film industry.中国最大的视频网站优酷土豆(Youku Tudou)周四宣布将设立自己的电影工作室,以便从中国电影市场分得更大份额。Victor Koo, chairman and chief executive of the company, said the film division, Heyi Film, would produce eight films per year destined for the big screen and a further nine aimed to premiere on the internet. The group, which last week announced a loss of m for the second quarter despite increased revenues, has not revealed how much it plans to spend on the project.优酷土豆首席执行官古永锵(Victor Koo)表示,这个名为合一影业(Heyi Film)的新电影公司将每年制作八部大屏幕电影,还会制作九部首发于互联网的影片。就在上周,优酷土豆曾宣布,尽管第二季度营收出现增长,该季度合计却亏损了2600万美元。目前,该集团并未披露打算往合一影业投入多少资金。Mr Koo said Youku had .6bn in cash to spend after a .2bn investment by ecommerce group Alibaba in April. “We’re very strong,” he said.古永铿表示,在今年4月获得电子商务集团阿里巴巴(Alibaba)的12亿美元投资后,优酷土豆目前可配的现金高达16亿美元。他说:“我们的现金非常充裕。”Youku Tudou, formed by the merger of China’s two largest sites in 2012, claims 500m users.优酷土豆由中国两家最大的视频网站在2012年合并而成,声称拥有5亿用户。Youku had been making its own content since 2009, starting with “microfilms” lasting a few minutes, and last year helped produce eight feature films that had a combined box office of 2bn, Mr Koo said. It planned a number of new releases in the coming months such as Golden Era, a film about China writers in the 1920s scheduled for release in October, and The Taking of Tiger Mountain, a 3D epic.古永铿表示,优酷自2009年开始就一直在制作自己的视频,起初是长度只有几分钟的“微电影”。去年该集团帮助制作了八部电影,票房总收入达20亿元。在今后几个月,它计划出品多部新影片,包括定于今年10月发行的《黄金时代》(Golden Era)(该片讲述了上世纪20年代中国作家的故事),以及3D史诗巨作《智取威虎山》(The Taking of Tiger Mountain)。The Continent, another big budget film partly financed by Youku, has made Rmb627m this year and is still in cinemas.今年,优酷参与投资的另一部大预算电影是《后会无期》(The Continent),该片的票房已达6.27亿人民币,目前仍在上映。Virtually all of China’s hosting sites make their own content, and this year has seen a trend to build separate studios or to acquire content producers. In July Iqiyi, which counts Baidu, China’s largest search engine, as an investor, launched an in-house studio with eight films in the works. In June Alibaba completed the acquisition of a majority stake in ChinaVision , a content maker.中国几乎所有视频网站都在制作自己的视频内容,今年甚至出现了一个新潮流,即这些网站成立独立的电影工作室或收购内容制作商。今年7月,依靠中国最大搜索引擎百度的投资,爱奇艺(Iqiyi)启动了一个内部工作室,正在制作八部影片。今年6月,阿里巴巴收购了视频内容制作商——文化中国传播(ChinaVision Media Group)的多数股权。The bid to move from small smartphone screens to big screens, and the reverse, is driven partly by strong growth over the past three years in films. China’s industry is the second largest after the ed States, expected to gross between Rmb28bn to Rmb30bn this year.过去三年,中国电影业强劲增长,推动业界从智能手机屏幕向大屏幕——或者相反——的迁徙。目前,中国是仅次于美国的第二大电影市场,预计今年票房总额将在280亿人民币到300亿人民币之间。Cinemas are multiplying, at an average rate of 18 screens a day. Last year China added more screens that the total in France.中国的电影院数量也在成倍增长,平均每天增加18块银幕。中国去年一年增加的银幕数就超过了法国的电影银幕总数。Allen Zhu, Heyi Film chief executive, said the studio planned five films based on hit internet series such as Yes Boss, Surprise and Miss Puff.合一影业首席执行官朱辉龙(Allen Zhu)表示,该公司还根据红极一时的网络剧制作了五部电影,其中包括《报告老板》(Yes Boss)、《万万没想到》(Surprise)和《泡芙》(Miss Puff)。Producing films for smartphone screens required a different approach, with smartphones running s getting very hot after 20 mins, said Mr Zhu. Surprise, broken into six-minute episodes, had gained 700m views.朱辉龙表示,为智能手机制作电影不同于制作大银幕电影,因为智能手机在观看视频20分钟后就会非常烫手。为此,吸引了7亿观众的《万万没想到》就分成了长度为6分钟的小段视频。 /201409/325356
