如今,智能手機的內(nèi)置攝像頭質(zhì)量越來越好,但最終還是受到了物理因素的制約:由于制造商試圖保留智能手機輕薄的特點,因此很難將一個尺寸合適的變焦鏡頭塞進(jìn)機身。
但在過去的一兩年里,該行業(yè)出現(xiàn)了新的解決辦法,可以使用更大的變焦鏡頭。天風(fēng)國際證券的蘋果分析師郭明琪表示,iPhone也將使用這一技術(shù)。他還指出,該技術(shù)蘋果版的研發(fā)還需要幾年時間,但很可能會在2022年推出。傳聞今年iPhone的一大新增功能是可以兼容超高速5G無線網(wǎng)絡(luò)。
改進(jìn)手機攝像頭的基本竅門是將變焦鏡頭側(cè)向移動,并將其置于機身內(nèi)部,以避免攝像頭凸起的情況。手機將借助特殊的光學(xué)器件棱鏡,讓光折射入鏡頭組,從而組成潛望式的設(shè)計結(jié)構(gòu)。
這種改進(jìn)方式已經(jīng)運用到三星Galaxy S20 Ultra和華為P30 Pro等少數(shù)幾款手機上,使手機能夠放大遠(yuǎn)處的拍攝對象并得到清晰的照片。
目前,iPhone 11 Pro相機中的鏡頭可以在光學(xué)上放大兩倍,通過使用數(shù)字軟件技巧在畫面模糊的情況下放大接近10倍。相比之下,Galaxy S20 Ultra有一個潛望鏡鏡頭,能夠做到10倍變焦,利用數(shù)字技巧在模糊的情況下放大100倍。
這是通過S20 Ultra拍攝的一組照片,從完全沒有變焦到100倍變焦。如圖所見,高達(dá)30倍變焦的照片細(xì)節(jié)清晰。在50倍和100倍時,照片邊界開始模糊,但仍然可以很好地識別圖像。
然而,新的技術(shù)并不便宜。Ultra的起價為1400美元,比蘋果最貴的iPhone 11 Pro Max還要高27%。當(dāng)帶有變焦鏡頭的iPhone上市時,預(yù)計其價格會有所上漲。(財富中文網(wǎng))

Photography on smartphones has been getting better and better, but ultimately the laws of physics start to play a limiting factor. With phone makers trying to keep their devices thin and light, it’s hard to cram a decent-sized zoom lens into the body.
But in the past year or two, the industry figured out a new trick to allow for a much larger zoom lens. And usually reliable Apple analyst Ming-Chi Kuo of TF International Securities says it’s coming to the iPhone now, too. Kuo, who has connections with Apple suppliers in Asia, says the Apple version of the technology is still a few years away, however, likely arriving in 2022 iPhones. The big new feature rumored for this year’s iPhone is the addition of superfast 5G wireless connectivity.
To improve the phone camera, the basic trick is to turn the zoom lens sideways and place it inside the body of the phone, instead of protruding straight out of the back. To bring the image into the lens, the phone has a prism to reflect light into the lens at an angle. It’s the same principle enabling a submarine skipper to use a periscope to see what’s happening on the ocean’s surface.
The result, as seen in a few phones such as the Samsung Galaxy S20 Ultra and Huawei P30 Pro, is the ability to zoom in on a subject from afar and still take a sharp picture.
The lens in the current iPhone 11 Pro’s camera can zoom in two times optically and can get as close as 10X by using digital software tricks that make the picture a bit blurrier. By contrast, the Galaxy S20 Ultra has a periscope lens that can zoom in like an optical lens 10X quite sharply and then use digital tricks to zoom in 100X with some blurriness.
The results can be amazing. Here is a set of pictures that I shot on the S20 Ultra ranging from no zoom at all all the way to 100X. As you can see, up to 30X the picture quality is quite good with sharp details. At 50X and 100X, the edges start to blur, but you can still make out the picture well.
The new ability doesn’t come cheap, however. The Ultra starts at $1,400, 27% more than even Apple’s most expensive model, the iPhone 11 Pro Max. When the iPhone with a periscope zoom lens arrives on the market, expect a commensurate price jump.
