Ithebhulethi enekhamera ehamba phambili: iPad Pro

Uma sithatha leli nani esixoxe ngalo njengesilinganiso, kukhona ophumelelayo, futhi lowo akekho omunye ngaphandle kwe-iPad Pro , inguqulo ethuthukisiwe ye-iPad Air.

Naphezu kokuthi ayiziwa nhlobo, le divayisi inesistimu yekhamera enamalensi amabili angu-12MP emzimbeni wayo ongu-11 intshi, ehambisana nenzwa ye-ultrawide engu-10MP. Iyithebhulethi enekhamera enhle , ekwazi ukuqopha ividiyo ngesisombululo esifinyelela ku-4K. Iphinde ibe ne-sports autofocus, inzwa ye-LiDAR, kanye ne-LED flash—yini enye ongayifuna? Ngaphezu kwalokho, ikhamera ebheke phambili nayo isezingeni elihle (ngokwezindinganiso zanamuhla), ifinyelela ku-7MP, okungcono kunekhamera yangemuva kwamanye amaphilisi amaningi.

Ngokuphathelene nezinye izici zethebhulethi, azimbi neze. Idivayisi inikwe amandla yiprosesa ye-Apple M1 futhi iza ne-iOS 15 efakiwe, yize ingabuyekezwa ezinguqulweni zesikhathi esizayo ngaphandle kwezinkinga.

Uma ukhetha ukuthenga ithebhulethi kwamanye amabhrendi amakhulu, aziwayo anemakethe enkulu (yize i-Apple isiba yinto evamile), futhi uzimisele ukuyekethisa kancane emandleni ekhamera, kunezibhebhe ezingaba ngu-30 emakethe ezinekhamera engu-8MP noma ngaphezulu. Isibonelo, amanye amamodeli e-iPad noma amathebhulethi e-Samsung anamakhamera angu-8MP. Angase asebenze kahle futhi alungile ngokuphelele, kodwa akufani.

Kungakhathaliseki ukuthi ufuna enye yama-smartphone amakhulu kunawo wonke emhlabeni noma enye yamathebhulethi amancane kakhulu, i-Apple ikunikeze i-iPad Pro. Le thebhulethi, enekhamera enhle kakhulu, yamenyezelwa emcimbini oyinhloko njengedivayisi engama-intshi angu-11, encane futhi elula kune-iPad Air ne-iPad Mini , futhi inikeza nokuxhumeka kwe-4G LTE kanye nama-microphone amabili okushaya ucingo. Kulowo mcimbi, sathola ithuba lokuthola ukubukeka kokuqala nokusebenzisa inguqulo ye-Pro isikhashana, futhi samangazwa yi-chassis yayo elula nencane nokuthi bakwazile kanjani ukuhlanganisa ikhamera.

Isibonisi se-IPS se- iPad Pro esingu-2372x2048 pixel sasinokukhanya okuhle kanye namazinga ombala kuyunithi yedemo esiyihlolile. I-Apple ithi isibonisi singafinyelela kuma- nit angu -600 , njengoba sisebenzisa i-LTPS (i-polysilicon ephansi).

I-iPad Pro yenziwe nge-aluminium emnyama enomklamo we-unibody, okwenza ibe nobuhle obuncane kodwa obukhangayo. Ingu- 6.1 mm ubukhulu kuphela , okwenza ibe mncane kunabaningi babancintisana nayo. Isisindo sayo esingamagremu angu-469 siphinde siyinike ithuba elihle kunamanye amaphilisi anobukhulu obufanayo.

I-bezel ezungeze isibonisi se-iPad Pro ingu-2.99 mm kuphela, okuvumela isikrini ukuthi sithathe amaphesenti angama-80 ebusweni bangaphambili bedivayisi. I-Apple ifinyelele lo mklamo omuhle ngokusebenzisa umzimba we-aluminium owodwa owenziwe ngenqubo ekhethekile yokubumba nge-injection.

Ngaphandle kokukhanya komklamo, sithole ukuthi ukubamba i-iPad Pro njengethebhulethi ehamba phambili enekhamera bekunzima ngandlela thile. I-CEO ye-Apple u-Tim Cook ubonise ukuthi idivayisi ivumelana kanjani nanoma iyiphi indawo yasekhaya neyochwepheshe, kuyilapho i-iPad mini ingenzi, kodwa lokho kungahluka kuye ngezidingo zomuntu ngamunye.

Ngaphakathi, i-iPad Pro isebenzisa iprosesa ye-Apple M1. Iphinde inikeze i-RAM engu-6GB kanye nesitoreji sangaphakathi esingu-128, 256, noma 512 GB noma ngisho no-2TB , kuye ngenguqulo.

Ithebhulethi isekela ikhamera yangaphambili engu-7 MP enalensi ye-engeli ebanzi eyengeziwe yokuthatha izithombe ozishuthe zona eqenjini. Isofthiwe yekhamera ye-iPad iphinde ithuthukise izithombe ozishuthe zona ngezihlungi ezenzelwe ukuthambisa ubuso kanye newindi elincane lesithombe ozishuthe sona elivela esikrinini ukukusiza ukuthi uzimele kahle isithombe sakho. Ngakolunye uhlangothi, ikhamera yangemuva engu-12 MP isebenzisa ilensi ye-Sony Exmor ukuze inikeze ikhwalithi yesithombe engcono.

Ithebhulethi isebenzisa inguqulo ye-iOS 15 eshintshwe kancane kusukela ku-iOS 14. I-iPad Pro esiyihlolile ayizange ibe nokwenza ngokwezifiso okuningi kufomu noma imisebenzi yesofthiwe. Besibona ukuthi isoftware yekhamera inemodi yesithombe ozishuthe sona kanye nezinketho zokushelela ubuso, kodwa iningi lezinhlelo zokusebenza bekuyizinguqulo ze-Apple zezinsizakalo ezijwayelekile ezifana nesibali njengesibonelo.

Okokugcina, ake sixoxe kancane ngokuthi kufanele uyithenge yini le thebhulethi noma cha. Akungabazeki ukuthi uma ufuna ithebhulethi enekhamera enhle, i-Apple iPad Pro iyisinqumo esihle kakhulu . Ikakhulukazi uma uthanda ukuthatha izithombe zakho, kungaba uwedwa noma eqenjini, le divayisi izodlula konke okulindelwe. Uma kunjalo, kunconywa kakhulu. Vele, uma ufuna ezinye izici ngaphandle kwekhamera nje, noma uma ufuna ithebhulethi enosayizi wesikrini ohlukile, kunezinketho eziningi ezitholakalayo, futhi kukuwe ukukhetha ekufanele.

Indlela yokukhetha ithebhulethi ngekhamera enhle

Inombolo yamagumbi

Ekuqaleni, amakhamera efoni ayengemahle kakhulu, futhi kwakukhona elilodwa kuphela. Elilodwa kufanele libe yinto evamile, kodwa hhayi kumadivayisi amancane njengezingcingo namathebulethi. Ngesinye isikhathi, ukuze kuthuthukiswe kwezinye izici, kudingeka enye yezinto ezimbili: kungaba ikhamera ebanzi noma eziningana ezilingana endaweni efanayo . Abakhiqizi bakhethe inketho yesibili, yingakho amadivayisi anamakhamera amabili, amathathu, noma ngaphezulu—noma amalensi, uma sifuna ukucacisa—manje asekhona.

Ngakho-ke yini ongayifeza ngamalensi engeziwe? Lokho kuncike kumkhiqizi. Enye inkampani icabange ukuthi kungaba ngumqondo omuhle ukuthatha izithombe ze-3D, kodwa lokhu akuzange kuphumelele. Kamuva, i-Apple yaba nomunye umqondo: ukuthuthukisa izici ezifana nokusondeza noma, okubaluleke kakhulu, ukudala imodi yesithombe edumile eletha isihloko esiyinhloko ekugxilweni okubukhali futhi ifiphaze ingemuva. Lo mphumela ungafezwa kuphela ngokuthembekile nge-AI enhle kakhulu, ukufunda komshini, noma amakhamera amaningi, ngakho-ke uma sifuna ikhwalithi engcono kakhulu, sidinga ukucabangela inani lamakhamera ithebhulethi eliwafakayo nokuthi yini esingayenza ngawo.

Megapixels

"Ikhamera yami ine-12MP kanti eyakho ine-8MP kuphela, ngakho ingcono kuneyakho." Wake wayifunda noma wezwa into efana naleyo? Kalula nje, lokhu akulona iqiniso, futhi kuyiphutha elivamile phakathi kwalabo abangazi lutho ngezithombe: ukugxila ezinombolweni ezisetshenziselwa ukuthengisa kuphela. Ama-Megapixel awachazi ikhwalithi yezithombe, kodwa kunalokho usayizi wazo . Kusho ukuthini lokhu? Nokho, umuntu othi ikhamera yakhe ine-12MP angaphrinta noma abuke izithombe zakhe kuma-canvases amakhulu kunomuntu onekhamera engu-8MP ngaphandle kokulahlekelwa ikhwalithi, kodwa ikhwalithi yokuphrinta ingase ibe yimbi. Umuntu onekhamera engu-8MP angaphrinta izithombe zakhe ngekhwalithi ephezulu, kodwa ngosayizi omncane.

Lokhu kuyinto okufanele uyikhumbule . Uma sifuna ukuthatha izithombe ngethebhulethi bese sabelana ngazo ukuze sizibuke kwamanye amathebhulethi noma omakhalekhukhwini, ama-megapixel awabalulekile kangako. Kodwa-ke, uma umsebenzi wethu noma into esiyithandayo idinga ukuthi sithathe izithombe ezinkulu, khona-ke sidinga ukufuna eyodwa enenani elihle lama-megapixel, kodwa ezinye izinto, njengokuvula kanye nosayizi wamaphikseli, nazo zibalulekile.

Apertura

Njengoba sisanda kuchazile, i-aperture ibaluleke kakhulu kunenani lama-megapixel. Okungenani lokho kuyiqiniso uma ungathathi isithombe ngaphandle emini ekhanyayo. I-aperture ikutshela ukuthi ilensi ingaphatha ukukhanya okungakanani . Uma i-aperture ibanzi, ivumela ukukhanya okwengeziwe, okuholela ezithombeni ezingcono ezimweni zokukhanya ezingaphelele.

Njengoba sesichaze kafushane okungenhla, kubalulekile ukusho imininingwane eyodwa: imbobo ivame ukukhonjiswa ngohlamvu "f" kanye nenombolo enciphayo njengoba imbobo ikhula . Ngamanye amazwi, ilensi enembobo ye-f/1.8 inkulu kunelena ene-f/2.2. Uma inani lezinombolo lincane, ikhwalithi iba phezulu, njalo kubhekiselwa ekudlulisweni kokukhanya.

Flash

Wonke umuntu uyazi ukuthi iyini i-flash yekhamera. Ngaphandle kwabo, ukuthatha isithombe sendawo ekhanyayo bekungeke kwenzeke. Empeleni, yisibani esikhanya ngesikhathi esifanele lapho uthatha isithombe ukuze sikhanyise lokho ofuna ukukuthatha. Kodwa akuwona wonke ama-flash afanayo, futhi kusekhona umehluko okufanele ucatshangelwe.

Usayizi we-flash ungabaluleka kancane, kodwa amandla abaluleke kakhulu. I -flash ye-LED enhle ingakhanyisa ngisho negumbi elimnyama ngokuphelele. Kodwa singaphinde sicabangele omunye umniningwane: ukuthi i-flash inemibala eminingi yini. I-flash enemibala emibili, ehlanganiswe nesofthiwe yedivayisi, inganquma ukuthi kudingeka ukukhanya okungakanani kombala ngamunye, okungabangela, isibonelo, izithombe ezinobuso obubonisa imibala engokoqobo, kunokuba ubuso obukhanyayo.

Futhi nakuba ngicabanga ukuthi kunezinketho ezimbalwa emakethe, uma uthola okuthile okune- xenon flash, angikukhuthazi ukuthi ukuthenge . Zinhle, kodwa hhayi kumadivayisi eselula, ngokwengxenye ngoba zikhipha ibhethri ngemva kokudubula okumbalwa nje. Yingakho zingekho nhlobo.

Inzwa ye-LiDAR

Obunye bobuchwepheshe bamuva obutholakala kumakhamera amadivayisi eselula namathebulethi yi-LiDAR. Imele i-Light Detection and Ranging, futhi isetshenziselwa ukunquma ibanga ukusuka ku-laser emitter kuya entweni noma endaweni kusetshenziswa i-pulsed laser beam. Ngenxa yalo msebenzi, ikhamera ingaqoqa ulwazi olwengeziwe futhi ithathe izithombe ezingcono, kodwa futhi inezinye izinhlelo zokusebenza ezifana nokuskena izinto.

Isofthiwe yekhamera

Kodwa i-hardware akuyona yodwa into ebalulekile; isofthiwe nayo ibaluleke kakhulu . Eqinisweni, ngeke ngikhulume nganoma yiziphi izinhlobo, kodwa kube nezimo zamafoni anamakhamera amahle kakhulu awonakele yisofthiwe, ekhiqiza izithombe ezinemibala egqamile, umsindo… inhlekelele enkulu. Inkinga lapha ukuthi kunzima ukwazi ukuthi yimaphi amafoni anesofthiwe enhle nokuthi yimaphi angenayo, kodwa sizozama ukunikeza iseluleko.

Ikhamera ethandwa kakhulu emhlabeni yi-iPhone, hhayi ngoba iyona engcono kakhulu, kodwa ngoba ikuselula esiyiphathayo futhi ikhamera yayo "iqondile futhi ithwetshulwe." Lokhu kusho ukuthi singayikhipha ifoni, siyikhombe, sicindezele inkinobho, bese isithombe ngokuvamile sizophuma kahle, ngakho akudingeki sibe abathwebuli bezithombe abangochwepheshe. Lokhu kufezwa ngokuhlanganisa ihadiwe nesofthiwe, ecubungula isithombe ngaphambi kokusibonisa.

Kunoma ikuphi, noma ngabe iyiphi ifoni noma ithebhulethi esinayo, inqobo nje uma kuyi-iOS noma i-Android (njengoba inezinhlelo zokusebenza eziningi kakhulu ezitholakalayo), singahlala sifuna izinhlelo zokusebenza zekhamera ezivela eceleni ku-App Store naku-Google Play. Lokhu, ngokombono, kuzoxazulula ukucutshungulwa kwezithombe okuzenzakalelayo okungekuhle kwedivayisi. Futhi endabeni yama-iPhone/iPad, izinhlelo zokusebenza ezivela eceleni zizosinika nokufinyelela kuzici ezithuthukisiwe kakhulu kubathwebuli bezithombe abadinga ulwazi oluningi.

Ikhwalithi yokurekhoda ividiyo

Ngaphandle kokuthatha izithombe, amakhamera angaqopha namavidiyo . Singase sicabange ukuthi ikhamera enhle izokwenza amavidiyo amahle ngokuzenzakalelayo, kodwa lokhu akunjalo ngaso sonke isikhathi, noma okungenani hhayi ngezinga ebelingenza ngalo. Kuyiqiniso ukuthi ikhamera ene-aperture enhle, inani lama-megapixel, njll., izokhiqiza amavidiyo ekhwalithi enhle, kodwa azikho yini ezinye izinketho? Yebo, zikhona, futhi kufanele zicatshangelwe.

Nakuba kungewona wonke amakhaya emhlabeni anayo okwamanje, ama-monitor namathelevishini e-4K aya ngokuya evame kakhulu . Ngakho-ke, uma sifuna ukubukela amavidiyo ngesisombululo esingcono kakhulu ku-TV yethu ye-4K, ikhamera yevidiyo yethebhulethi yethu idinga ukusekela leyo khwalithi. Ikhwalithi yevidiyo izothuthukiswa futhi yi-FPS ( ozimele ngomzuzwana ) lapho ingaqopha khona. I-FPS ibhekisela enanini "lezithombe" ithebhulethi engazithatha ngomzuzwana. Uma i-FPS iphakeme, ikhwalithi iba ngcono.

Ngaphezu kwalokhu okungenhla, kunelinye iphuzu elibalulekile okufanele licatshangelwe: ikhono lokurekhoda ngokuhamba kancane . Eyaziwa nangokuthi i-SloMo noma ukuhamba kancane, lesi sici sivumela ukuthi siqophe ngesilinganiso sohlaka esiphezulu (i-FPS), ngokuvamile siqala ku-120fps, kodwa futhi kungenzeka ukurekhoda ku-240fps noma ngaphezulu. Lapho sibuyekeza lesi sici, sidinga futhi ukuhlola isinqumo lapho singaqopha khona ngokuhamba kancane, njengoba kungenzeka ukuthi isinqumo se-4K esingaqopha ngesivinini esijwayelekile sizokwehla siye ku-720p lapho siqopha ku-SloMo.

Indlela yokukhetha ithebhulethi enekhamera engaphambili enhle

Ngesikhathi se-Covid, ukusebenzelana ngocingo sekungomunye umngane wabaningi bethu futhi lokho kubangele ukuthi singagcini nje ngokudinga ithebhulethi enekhamera engemuva enhle, kodwa futhi nekhamera enhle yangaphambili.

Kulokhu, ikhamera engaphambili iyaqhubeka nokunganakwa kakhulu kumamodeli amaningi, inikeza ikhwalithi efanele kuphela.

Nakuba inzwa enama-megapixel amaningi ayihlali ingcono ngaso sonke isikhathi, njengoba okwamanje, amakhamera ahlanganisa obunye ubuchwepheshe nezixazululo zokuyithuthukisa, njengokusetshenziswa kwe-AI ye-autofocus, ukuqashelwa kobuso, izihlungi, njll.
• Izinga lozimele kanye nesivinini sokudubula: Nakuba lawa manani engavamile ukunikezwa kwezinye izincazelo, futhi kuyisici esibalulekile lapho ukhetha inzwa yezithombe. Izobonisa inani le-FPS ekulungisweni okuthile ukuze urekhode ividiyo. Isibonelo, ikhamera engu-1080p @ 60 iphansi kune-1080p @ 120, njengoba eyesibili ingafinyelela kumafreyimu angu-120 ngesekhondi eshuthiwe, inikeze ividiyo emanzi. Mayelana ne-shutter noma isivinini sokudubula, isabela esikhathini sokuchayeka lapho i-shutter yekhamera ivuleka ngokuthwebula ukukhanya okwengeziwe.
• Usayizi wenzwa: ibalulekile futhi, futhi kukhona ¼ ”, ⅓”, ½ ”, 1 / 1.8”, ⅔ ”, njll. Ngokuvamile, uma kukhudlwana, kungcono, nakuba endabeni yamakhamera angaphambili ngokuvamile mancane ngenxa yokulinganiselwa kwesikhala nesikrini.
• Imbobo yokugxila: uhlamvu f lusetshenziselwa ukuyichaza, futhi ukukhanya inzwa engakwazi ukuyithwebula nge-diaphragm kuzoncika kuyo. Imbobo enkulu imelelwa inombolo encane ka-f, ngakho-ke kuhle ukubheka izinombolo eziphansi kakhulu ngangokunokwenzeka. Isibonelo, u-f/2 ungcono kuno-f/8.
• Ukujula kombala: Kubalulekile ukuthi ibe nokujula kombala okungcono, ukuze kube khona umehluko omncane ngezithombe zangempela.
• Ibanga elinamandla: Uma benobuchwepheshe obufana ne-HDR, HDR10 noma i-HDR +, ikhamera izokwazi ukuthwebula kangcono izithunzi nokugqama, ngezithombe ezicace kakhulu.
• Ukusebenza ebumnyameni: Uma ufuna ukuthwebula izithombe ebusuku, noma ezindaweni ezinokukhanya okubi, inzwa enemodi yasebusuku kanye ne-ISO ephakeme nayo ibalulekile. I-ISO inquma ukuthi inzwa izwela kangakanani ekuthwebuleni ukukhanya.
• Isihlungi se-IRAmakhamera ekhwalithi ephezulu kuphela asebenzisa isihlungi sokukhanya kwe-infrared ukuze izithombe noma amavidiyo aphume aphelele, ngaphandle kokushintshwa yilolu hlobo lwe-electromagnetic beam. Ngokuvamile, amamodeli we-premium kuphela ayihlanganisayo, njenge-Apple. Ukuze wenze uhlolo, ungakhomba isilawuli kude se-TV yakho kukhamera ngenkathi ithwebula isithombe. Uma inesihlungi ngeke ukwazi ukubona noma yini eyinqaba, kodwa uma ingenaso isihlungi uzokwazi ukubona ukuthi i-IR emitter yesilawuli kude sikhipha kanjani ukukhanya ngethoni ephinki.
• IA: Njengoba ngishilo ekuqaleni, kungcono ukuba namakhamera anemisebenzi yobuhlakani bokwenziwa engangeza okungeziwe kuma-selfies akho, amakholi wevidiyo, njll. Ngenxa yale misebenzi, ngeke ikwazi kuphela ukubona ubuso bakho ukuze uvulele amasevisi, izokwazi futhi ukubona ukuthinta, isebenzise izihlungi, yenza izinguquko njengoba kudingeka, noma ithathe indlela efanele. Isibonelo, i-Apple iyi-ace yalezi zinhlobo zokuthuthuka.
