Until a few years ago even the best digital camera couldn't fix an out-of-focus photo.
幾年前即使是最好的數(shù)碼相機(jī)也搞不定一張失焦的照片，但最近情況有了改善。
A start-up called Lytro introduced a solution to this in 2012 when they created a camera that lets you snap pictures and play with the focus afterward.
2012年一家名為Lytro的新興高科技公司提出了一種新的解決方案，當(dāng)時(shí)他們?cè)O(shè)計(jì)出一款可以使你享受先拍照后調(diào)焦的相機(jī)。
That neat gadget cost $400 and looked like a mini telescope.
當(dāng)時(shí)這臺(tái)秀氣的小玩意價(jià)值400美元，看上去就像個(gè)迷你望遠(yuǎn)鏡。
A new version expected this summer will offer additional advances.
今年夏天它的最新款即將與我們見面，或許還會(huì)有更多驚喜。
Called the Lytro Illum, it looks like a serious SLR camera and has a 1,600 price tag.
這款名為Lytro Illum的相機(jī)造型和高端專業(yè)單反相機(jī)類似，定價(jià)更是達(dá)到1600美元。
The Illum still uses a special sensor covered by a matrix of microlenses, which capture the entire light field.
新款I(lǐng)llum仍然使用微透鏡陣列為矩陣式排列的特殊感光元件，從而可以捕捉全區(qū)的光場(chǎng)攝影領(lǐng)域。
That's an enormous amount of data about the color, brightness and direction of all light rays within a frame.
這可是在成像區(qū)域內(nèi)對(duì)于顏色、光強(qiáng)以及所有光線反射等海量的數(shù)據(jù)信息。
The camera doesn't have a focus mechanism—it comes up with an image based on a massive data analysis.
這臺(tái)相機(jī)并沒有傳統(tǒng)的焦距—它的成像原理是依據(jù)龐大的數(shù)據(jù)分析。
You can then go in and change its choices.
你可以進(jìn)入系統(tǒng)并進(jìn)行改動(dòng)。
The Illum improves on the original Lytro with a much faster sensor and processor, the same one Samsung uses in its new Galaxy S5 smartphone.
相比第一代，Illum經(jīng)過改良擁有更快速的傳感器和處理器，而同樣的元件三星也用在了自家最新的Galaxy S5 智能手機(jī)上。
Probably more camera than most of us need.
或許我們對(duì)相機(jī)的要求遠(yuǎn)遠(yuǎn)低于現(xiàn)在這些浩如繁星的高科技設(shè)備。
But a lifesaver when you screw up a once-in-a-lifetime photo.
但是當(dāng)你搞砸了一生中唯一一張珍貴照片時(shí)，這臺(tái)相機(jī)或許能夠解決你的燃眉之急。
