Adam Kos Cov xov tooj ntawm tes tau raug nqi "lub neej" ntawm ntau yam khoom siv hluav taws xob. Ua tsaug rau lawv, peb tsis xav tau lub tshuab xam zauv, MP3 players, handheld game consoles, lossis compact cameras (thiab rau qhov teeb meem ntawd, DSLRs). Thawj qhov uas tau hais los no tsis tau nce mus ntau, txawm li cas los xij, kev yees duab thiab yees duab tuaj yeem txhim kho tas li. Nws yuav tsum tsis muaj qhov sib txawv hauv 2022 ib yam.
Thaum Apple nthuav tawm iPhone 2015S hauv 6, nws yog thawj lub xov tooj 12MP. Ntau tshaj 6 xyoo tom qab, txawm tias tam sim no iPhone 13 series khaws qhov kev daws teeb meem no. Yog li qhov kev hloov pauv ntawm kev loj hlob nyob qhov twg? Yog tias peb tsis suav qhov sib ntxiv ntawm lo ntsiab muag (ntawm tib qhov kev daws teeb meem), qhov no yog qhov kev nce ntxiv hauv lub sensor nws tus kheej. Ua tsaug rau qhov no, lub koob yees duab kaw lus txuas ntxiv mus rau sab nraub qaum ntawm lub cuab yeej ntau thiab ntau dua.
Cov duab thaij duab
Tom qab tag nrho, muab piv rau koj tus kheej. Lub iPhone 6S muaj ib qho 1,22 µm sensor pixel. Ib pixel ntawm lub koob yees duab dav dav ntawm iPhone 13 Pro muaj qhov loj ntawm 1,9 µm. Tsis tas li ntawd, kho qhov muag stabilization ntawm lub sensor tau ntxiv thiab lub aperture kuj tau txhim kho, uas yog f / 1,5 piv rau f / 2,2. Nws tuaj yeem hais tias kev yos hav zoov rau megapixels dhau mus rau qee qhov. Txhua lub sijhawm tam sim no thiab tom qab ntawd cov chaw tsim khoom tawm los uas xav nqa qee tus lej ua pa, tab sis raws li peb paub, megapixels tsis ua duab. Piv txwv li, Samsung tau qhia peb qhov no nrog nws tus qauv Galaxy S21 Ultra.
108 MPx tej zaum yuav suab zoo, tab sis thaum kawg nws tsis yog lub yeeb koob. Txawm hais tias Samsung tswj kom ua tiav f / 1,8 apertures, pixel loj tsuas yog 0,8 µm, uas feem ntau ua rau muaj suab nrov loj. Tias yog vim li cas txawm nyob rau hauv cov kev teeb tsa yooj yim nws sib txuas ntau pixels rau hauv ib qho, yog li koj yuav tsis siv lub peev xwm ntawm ntau tus pixels lawm. Nws kuj tau sim nws nrog periscope mus kom ze, qhov twg 10MPx sensor muab 10x zoom. Nws zoo nkaus li zoo ntawm daim ntawv, tab sis qhov kev muaj tiag tsis zoo heev.

Megapixels thiab periscope
Feem ntau cov high-end smartphones ntawm ntau lub npe muab qhov kev daws teeb meem ntawm lawv lub koob yees duab dav dav ntawm ib ncig ntawm 50 MPx. Apple yuav tsum nce lawv qhov kev ua si xyoo no thiab nrog kev qhia txog iPhone 14 Pro lawv yuav muab lawv lub koob yees duab loj 48 MPx. Tom qab ntawd nws yuav ua ke 4 pixels rau hauv ib qho yog tias qhov chaw tsis muaj teeb pom kev zoo. Cov lus nug yog yuav ua li cas lawv yuav lis nws nyob rau hauv cov nqe lus ntawm pixel loj. Yog tias nws xav kom nws loj npaum li qhov ua tau, cov khoom tso tawm tom qab ntawm lub cuab yeej yuav nce ntxiv. Tsis tas li ntawd, lub tuam txhab yuav tsum tau kho dua tshiab, vim hais tias cov lo ntsiab muag tsuas yog tsis haum rau ib sab ntawm qhov kev npaj tam sim no. Tab sis nrog kev hloov kho no, cov neeg siv yuav tau txais lub peev xwm tua 8K video.
Samsung Galaxy S21
Muaj kev xav txog lub lens periscope nrog rau iPhone 15. Yog li peb yuav tsis pom nws xyoo no. Qhov no feem ntau yog vim qhov tseeb tias tsis muaj chaw rau nws hauv lub cuab yeej, thiab Apple yuav tsum tau hloov pauv nws tus qauv tag nrho. Uas tsis xav tau los ntawm lub xyoo no (nws yuav tsum tseem zoo li iPhones 12 thiab 13), thaum nws yog los ntawm ib qho hauv 2023. Lub periscope system ua haujlwm los ntawm kev xav txog lub teeb los ntawm lub iav inclined ntawm lub sensor, uas nyob ntawm nws qhov kawg. Qhov kev daws teeb meem no tsis tas yuav muaj cov khoom tso tawm, vim tias nws tau muab zais tag nrho hauv lub cev. Tsuas yog rau tus qauv Galaxy S21 Ultra, nws kuj tseem suav nrog hauv Huawei P40 Pro +.

Cov ntsiab lus tseem ceeb
Raws li deb li megapixels muaj kev txhawj xeeb, cov neeg tsim khoom feem ntau tau nyob ib puag ncig 50 MPx nyob rau hauv rooj plaub ntawm lub ntsiab lens. E.g. xiaomi 12 pro Txawm li cas los xij, nws twb muaj lub koob yees duab triple, qhov twg txhua lub lens muaj 50 MPx. Qhov ntawd txhais tau tias tsis yog ob lub telephoto lens xwb tab sis kuj yog ultra-wide-angle. Thiab nws zoo li lwm tus yuav ua raws li kev cai.
Optical zoom nyob rau hauv cov ntaub ntawv ntawm lub periscope lens yog 10x zoom. Cov neeg tsim khoom tej zaum yuav tsis txuas ntxiv mus rau ntawm no. Nws tsis ua rau muaj kev nkag siab ntau. Tab sis nws tseem xav txhim kho lub aperture, uas tsuas yog phem. Yog li tsis txhob ua rau kuv yuam kev, nws zoo kawg rau lub xov tooj ntawm tes uas nws tuaj yeem yog f / 4,9, tab sis koj yuav tsum coj mus rau hauv tus account tias tus neeg siv nruab nrab tsis tau hnia DSLR thiab tsis muaj qhov sib piv. Txhua yam lawv pom yog qhov tshwm sim, uas tsuas yog nrov nrov.
Ntawm chav kawm, kho qhov muag stabilization twb xav tau nyob rau hauv high-end pab kiag li lawm, yog hais tias lub sensor yog tam sim no, nws tsuas yog zoo. Lub neej yav tom ntej nyob rau hauv no hais txog yog nyob rau hauv kev siv ntawm ib tug scaled-down gimbal. Tab sis yeej tsis yog xyoo no, tej zaum tsis yog xyoo tom ntej.

software
Yog li qhov tseem ceeb hauv 2022 tej zaum yuav tsis tshwm sim ntau hauv hardware li hauv software. Tej zaum tsis muaj ntau nrog Apple, tab sis theej nrog kev sib tw. Xyoo tas los, Apple tau qhia peb txog hom yeeb yaj kiab, Cov Qauv Duab, macro thiab ProRes. Yog li ntawd, kev sib tw yuav ntes tau nrog nws nyob rau hauv no hais txog. Thiab nws tsis yog lo lus nug ntawm yog tias, tab sis thaum twg nws yuav ua tiav.
