Androids amadalira laser focus, koma iPhone amapita njira ina. Chifukwa chiyani?

M’zaka zaposachedwapa, dziko la mafoni a m’manja laona kusintha kwakukulu. Titha kuwona kusiyana kwakukulu m'mbali zonse, mosasamala kanthu kuti timayang'ana kwambiri kukula kapena kapangidwe, magwiridwe antchito kapena ntchito zina zanzeru. Ubwino wa makamera pakadali pano umagwira ntchito yofunika kwambiri. Pakalipano, tikhoza kunena kuti ichi ndi chimodzi mwa zinthu zofunika kwambiri pa mafoni a m'manja, momwe ma flagships amapikisana nthawi zonse. Kuphatikiza apo, tikayerekeza, mwachitsanzo, mafoni a Android ndi iPhone ya Apple, timapeza zosiyana zingapo zosangalatsa.

Ngati muli ndi chidwi ndi dziko laukadaulo wam'manja, ndiye kuti mukudziwa kuti chimodzi mwazosiyana kwambiri zitha kupezeka pankhani yakusintha kwa sensor. Ngakhale ma Android nthawi zambiri amapereka mandala opitilira 50 Mpx, iPhone yakhala ikubetcha pa 12 Mpx kwa zaka zambiri, ndipo imatha kuperekabe zithunzi zabwinoko. Komabe, sizimaperekedwa chidwi kwambiri pamakina owunikira zithunzi, pomwe timakumana ndi kusiyana kosangalatsa. Mafoni opikisana omwe ali ndi makina ogwiritsira ntchito a Android nthawi zambiri (pang'ono) amadalira zomwe zimatchedwa laser auto focus, pomwe mafoni a m'manja okhala ndi logo yolumidwa ya apulo alibe lusoli. Kodi zimagwira ntchito bwanji, chifukwa chiyani zimagwiritsidwa ntchito komanso ndi matekinoloje ati omwe Apple amadalira?

Laser Focus vs iPhone

Ukadaulo wowunikira wa laser womwe watchulidwa umagwira ntchito mophweka ndipo kugwiritsa ntchito kwake kumamveka bwino. Pankhaniyi, diode imabisika mu gawo lachithunzi, lomwe limatulutsa ma radiation pomwe choyambitsacho chikanikizidwa. Pankhaniyi, mtengo umatumizidwa, womwe umadumpha pamutu wojambulidwa / chinthu ndikubwerera, nthawi yomwe ingagwiritsidwe ntchito kuwerengera mwachangu mtunda kudzera pamapulogalamu apulogalamu. Tsoka ilo, ilinso ndi mbali yake yakuda. Mukajambula zithunzi patali kwambiri, kuyang'ana kwa laser sikukhalanso kolondola, kapena pojambula zithunzi za zinthu zowonekera ndi zopinga zabwino zomwe sizingawonetsere mtengowo. Pachifukwa ichi, mafoni ambiri amadalirabe ma aligorivimu otsimikiziridwa ndi zaka kuti azindikire kusiyana kwa mawonekedwe. Sensa yokhala ndi zotere imatha kupeza chithunzi chabwino. Kuphatikizikako kumagwira ntchito bwino kwambiri ndikuwonetsetsa kuyang'ana mwachangu komanso molondola. Mwachitsanzo, Google Pixel 6 yotchuka ili ndi dongosolo ili (LDAF).

Kumbali inayi, tili ndi iPhone, yomwe imagwira ntchito mosiyana. Koma kwenikweni ndi zofanana. Pamene choyambitsa chikanikizidwa, gawo la ISP kapena Image Signal processor, lomwe lasinthidwa kwambiri m'zaka zaposachedwa, limagwira ntchito yofunika kwambiri. Chip ichi chitha kugwiritsa ntchito njira yosiyanitsa ndi ma aligorivimu otsogola kuti iwunikire nthawi yomweyo zomwe zili bwino ndikujambula chithunzi chapamwamba kwambiri. Inde, kutengera zomwe zapezeka, ndikofunikira kusuntha mandala kumalo omwe mukufuna, koma makamera onse m'mafoni am'manja amagwira ntchito chimodzimodzi. Ngakhale kuti amayendetsedwa ndi "motor", kayendedwe kawo si kozungulira, koma mzere.

Gawo limodzi patsogolo ndi mitundu ya iPhone 12 Pro (Max) ndi iPhone 13 Pro (Max). Monga momwe mungaganizire, mitundu iyi ili ndi chojambulira chotchedwa LiDAR scanner, chomwe chimatha kudziwa nthawi yomweyo mtunda kuchokera pamutu wojambulidwa ndikugwiritsa ntchito chidziwitsochi kuti chipindule. M'malo mwake, ukadaulo uwu uli pafupi ndi zomwe tafotokozazi za laser. LiDAR imatha kugwiritsa ntchito mizati ya laser kuti ipange mtundu wa 3D wazozungulira, chifukwa chake imagwiritsidwa ntchito makamaka pakusanthula zipinda, m'magalimoto oyenda okha komanso kujambula zithunzi, makamaka zithunzi.
