Ama-Android athembele ekugxilweni kwe-laser, kodwa i-iPhone iya ngenye indlela. Kungani?

Eminyakeni yamuva, umhlaba womakhalekhukhwini uye wabona izinguquko ezinkulu. Singabona umehluko obalulekile kuzo zonke izici, kungakhathaliseki ukuthi sigxila kusayizi noma umklamo, ukusebenza noma eminye imisebenzi ehlakaniphile. Izinga lamakhamera njengamanje lidlala indima ebalulekile. Okwamanje, singasho ukuthi lokhu kungenye yezici ezibaluleke kakhulu zama-smartphones, lapho amafulegi ahlala eqhudelana khona. Ngaphezu kwalokho, uma siqhathanisa, isibonelo, amafoni we-Android ne-iPhone ye-Apple, sithola inani lokuhluka okuthakazelisayo.

Uma unentshisekelo emhlabeni wobuchwepheshe beselula, khona-ke uyazi ukuthi umehluko omkhulu ungatholakala endabeni yokuxazulula inzwa. Nakuba ama-Android evame ukunikeza ilensi enangaphezu kuka-50 Mpx, i-iPhone ibilokhu ibhejela ngo-12 Mpx kuphela iminyaka, futhi isenganikeza izithombe zekhwalithi engcono. Kodwa-ke, akunakwa kakhulu ezinhlelweni zokugxila kwesithombe, lapho sihlangabezana nomehluko othokozisayo. Amafoni ancintisanayo anesistimu yokusebenza ye-Android ngokuvamile (ingxenye) athembela kulokho okubizwa ngokuthi i-laser auto focus, kuyilapho ama-smartphone anophawu lwe-apula olunyiwe akanabo lobu buchwepheshe. Isebenza kanjani ngempela, kungani isetshenziswa futhi yiziphi ubuchwepheshe i-Apple ethembele kubo?

Ubuchwepheshe bokugxila kwe-laser obushiwo busebenza kalula futhi ukusetshenziswa kwabo kwenza umqondo omkhulu. Kulokhu, i-diode ifihliwe kumojula yesithombe, ekhipha imisebe lapho i-trigger icindezelwa. Kulesi simo, i-beam ithunyelwa ngaphandle, egxuma esihlokweni/entweni ethathwe isithombe bese ibuya, isikhathi esingasetshenziswa ukubala ngokushesha ibanga ngama-algorithms esofthiwe. Ngeshwa, nayo inohlangothi lwayo olumnyama. Uma uthatha izithombe emabangeni amakhulu, ukugxilwa kwe-laser akusanembe kangako, noma uma uthatha izithombe zezinto ezibonisa ngale kanye nezithiyo ezingezinhle ezingakwazi ukubonisa ngokuthembekile i-beam. Ngalesi sizathu, amafoni amaningi asathembele ku-algorithm efakazelwe ubudala ukuze athole ukungafani kwesigcawu. Inzwa enalokhu ingathola isithombe esihle kakhulu. Inhlanganisela isebenza kahle kakhulu futhi iqinisekisa ukugxila kwesithombe okusheshayo nokunembile. Isibonelo, i-Google Pixel 6 edumile inalolu hlelo (LDAF).

Ngakolunye uhlangothi, sine-iPhone, esebenza ngokuhlukile kancane. Kodwa emqondweni kuyefana ncamashi. Uma ucindezela i-trigger, i-ISP noma ingxenye ye-Image Signal Processor, ethuthukiswe kakhulu eminyakeni yamuva, idlala indima ebalulekile. Le chip ingasebenzisa indlela yokuqhathanisa nama-algorithms ayinkimbinkimbi ukuze ihlole ngokushesha ukugxila okuhle kakhulu futhi ithathe isithombe sekhwalithi ephezulu. Yiqiniso, ngokusekelwe kudatha etholiwe, kuyadingeka ukuhambisa i-lens ngomshini endaweni oyifunayo, kodwa wonke amakhamera kumakhalekhukhwini asebenza ngendlela efanayo. Nakuba zilawulwa "injini", ukunyakaza kwazo akuyona i-rotary, kodwa i-linear.

Isinyathelo esisodwa phambili amamodeli we-iPhone 12 Pro (Max) kanye ne-iPhone 13 Pro (Max). Njengoba ungase uqagele, lawa mamodeli afakwe okuthiwa yi-scanner ye-LiDAR, engakwazi ukunquma ngokushesha ibanga ukusuka esihlokweni esithwetshuliwe futhi isebenzise lolu lwazi ukuze izuze. Eqinisweni, lobu buchwepheshe buseduze nokugxila kwe-laser okukhulunywe ngakho. I-LiDAR ingasebenzisa imishayo ye-laser ukuze yakhe imodeli ye-3D yendawo eyizungezile, yingakho isetshenziselwa kakhulu ukuskena amagumbi, ezimotweni ezizimele kanye nokuthatha izithombe, ngokuyinhloko izithombe.
