通風(fēng)降溫設(shè)備生產(chǎn)廠: 'giant lobster' ate like a wha

  如今,隨著手機(jī)硬件不斷升級(jí),配備高像素?cái)z像頭的智能機(jī)應(yīng)運(yùn)而生,800萬和1300萬像素則是目前手機(jī)圈最為主流的。不過,像素在1300萬以上的也有不少,像MX4 Pro、聯(lián)想VIBE Shot、Lumia 1020等,它們完全可以和時(shí)下主流卡片機(jī)相媲美,特別是Lumia 1020那恐怖的4100萬像素,時(shí)至今日還沒有替代它的產(chǎn)品出現(xiàn),鋒速達(dá)通風(fēng)降溫設(shè)備生產(chǎn)廠得到了廣大客戶的一致好評(píng)。

  以上這些都是拍攝過程中不可或缺的要素,雖然目前大部分智能機(jī)還不能隨意調(diào)整光圈值的大小,但還有不少機(jī)型加入了手動(dòng)模式,這樣用戶可對(duì)ISO、曝光值、快門速度以及對(duì)焦方式等進(jìn)行控制,從而拍出想要的效果。不過,像努比亞這種以拍照為賣點(diǎn)的手機(jī)品牌不僅加入了電子光圈,還可實(shí)現(xiàn)對(duì)焦、測(cè)光分離,由此可見拍照手機(jī)有替代卡片相機(jī)之勢(shì)。


像素不代表一切

It also had pairs of fins along both sides of its 2m-long body, which are precursors of the double limbs seen in many of its living relatives.

  不過,別看Android陣營(yíng)沒有特別突出的拍照手機(jī),但其一直都在穩(wěn)步前進(jìn),像去年的vivo Xshot、三星GALAXY K Zoom以及聯(lián)想在今年MWC展會(huì)上發(fā)布的VIBE Shot等產(chǎn)品,不論外觀還是內(nèi)部?jī)?yōu)化相比之前的拍照手機(jī)提升不少,因此在成像效果上也不遜于卡片相機(jī),那從目前的形式來看拍照手機(jī)是否能夠取代卡片相機(jī)呢?下面我們就來聊聊這個(gè)話題!

The remarkable specimen was preserved in three dimensions, instead of being squashed flat like most previous examples of anomalocaridids. Dr Daley explained this was crucial to the findings.

  要說對(duì)成像質(zhì)量影響最大的是什么?這取決于傳感器面積的大小,因?yàn)閭鞲衅鞒叽缭酱,感光性能越好,可捕捉到的光子就越多,成像效果自然也越清晰。然而,大尺寸傳感器卻會(huì)導(dǎo)致手機(jī)的體積、重量、成本增加,而背照式和堆棧式傳感器的出現(xiàn)則解決了這一問題。

  回過頭來,看看當(dāng)下那些卡片數(shù)碼相機(jī),它們的傳感器尺寸大部分都是1/2.3英寸,而這一尺寸在近年發(fā)布的智能手機(jī)身上隨處可見,像OPPO N3、魅族MX4/Pro、三星GALAXY K Zoom等,可見手機(jī)廠商為了提升成像質(zhì)量下了不少功夫。

  反觀數(shù)碼相機(jī)行業(yè),2016年卡片數(shù)碼相機(jī)的像素基本維持在2000萬左右,與去年相比沒多大變化,而拍照手機(jī)的像素不但逐年穩(wěn)步提升,而且功能也比卡片相機(jī)豐富,不知此時(shí)佳能、尼康、索尼等數(shù)碼相機(jī)界大佬有何感想?

融合還是替代?

卡片機(jī)有的它都有

The beast belongs to a very early family of sea creatures called "anomalocaridids", which first appeared 520 million years ago during the Cambrian period. This new species, living some 40 million years later in the early Ordovician period, was probably among the last of its kind.

  其實(shí),說到拍照手機(jī),Android陣營(yíng)并沒有特別突出的產(chǎn)品,相反windows phone和iOS陣營(yíng)在拍照方面做的不錯(cuò),雖然諾基亞把手機(jī)業(yè)務(wù)賣給了微軟,但Lumia系列早已把手機(jī)的拍照功能做到了極致,像Lumia 1020那顆1/1.5英寸BSI背照式感光元件遠(yuǎn)超普通數(shù)碼卡片相機(jī),成像效果自然不用多說,而iPhone各方面都很均衡,成像效果除Lumia系列外也鮮有對(duì)手。

  不過,還有另一個(gè)原因,那就是移動(dòng)互聯(lián)網(wǎng)的興起,讓隨拍隨傳成為可能,試想一下你用卡片相機(jī)拍完照片之后,需找個(gè)能聯(lián)網(wǎng)的電腦才能上傳,和拿起手機(jī)點(diǎn)幾下直接上傳,哪種效率更高呢?答案不言而喻自然是后者,如果隨后幾年卡片相機(jī)還一直停步不前,相信被替代是遲早的事情。然而,未來的事情誰也說不準(zhǔn),也許手機(jī)、相機(jī)互相融合之后誕生出新的發(fā)展方向也不是沒有可能。

"This would have been one of the largest animals alive at the time," said Dr Allison Daley from Oxford University.

"We have found the oldest example of gigantism in a freely swimming filter feeder."

"Without these 3D remains, we may never have got the insight into these animals' anatomy that we did," she said.

The monster used spiny "limbs" on its head to sift food from the ocean.

Most of the anomalocaridids were predators that hunted and ate other marine animals. But the Aegirocassis seems to have used its head appendages, bristling with tiny spines, as a net to trap tiny tidbits of food - making it a "filter feeder" like present-day whales.

 




 

  此外,也許有人還認(rèn)為像素越高就越清晰,其實(shí)兩者并不能掛等號(hào),照片的清晰度與進(jìn)光量、傳感器面積大小以及拍攝者的使用技巧有關(guān),高像素則能夠還原被攝物體更多細(xì)節(jié),像拍攝人物時(shí),像素越高人臉上的毛細(xì)孔就越明顯,當(dāng)然看起來也更加真實(shí)。

  早些年的手機(jī)僅僅是人們用來接打電話的通訊工具,Android智能系統(tǒng)的誕生讓手機(jī)發(fā)生了翻天覆地的變化,由于此系統(tǒng)的源代碼可免費(fèi)拿來使用,這大大降低了制作手機(jī)的成本,因此國(guó)內(nèi)外手機(jī)廠商都會(huì)把Android系統(tǒng)拿來進(jìn)行深度優(yōu)化,正是基于此,手機(jī)的硬件配置也得到突飛猛進(jìn)的發(fā)展。如今,手機(jī)不但可以勝任商務(wù)辦公、休閑娛樂,而且在拍照方面也有不俗表現(xiàn)。

  在拍照過程中,光圈、ISO、對(duì)焦等對(duì)成像質(zhì)量很重要,同樣拍照手機(jī)也離不開它們的輔助,下面我們就來簡(jiǎn)單的介紹一下。光圈是一個(gè)用來控制進(jìn)光量的裝置,它通常是在鏡頭內(nèi),對(duì)于已經(jīng)制造好的鏡頭,我們不可能隨意改變鏡頭的直徑,但是我們可以通過在鏡頭內(nèi)部加入多邊形或者圓型,并且面積可變的孔狀光柵來達(dá)到控制鏡頭的進(jìn)光量。而表達(dá)光圈大小我們是用F值,F(xiàn)值越大進(jìn)光量越少,反之則越多。

This changes our picture of that period's marine environment, Dr Daley said.

The fossil itself was first found by fossil hunter Mohamed Ben Moula and is named in his honour: Aegirocassis benmoulae. The first part of the name refers to a giant Norse sea god (Aegir) and the Latin for helmet (cassis).

  其實(shí)仔細(xì)想想也不難理解,在拍照手機(jī)還未壯大的時(shí)候,卡片數(shù)碼相機(jī)以輕便的機(jī)身、出色的成像效果成為家庭用戶首選。然而,隨著拍照手機(jī)在軟硬件方面超越卡片相機(jī),其當(dāng)初的優(yōu)勢(shì)逐漸轉(zhuǎn)為劣勢(shì),雖然在此期間也推出過可通話卡片相機(jī),但只是曇花一現(xiàn)便被拍照手機(jī)的光芒所掩蓋。
