Adam Kos Tus naj npawb ntawm MPx thiab qhov ntev ntawm optical zoom yog qhov koj tuaj yeem pom thaum xub thawj siab ib muag txog lub koob yees duab specification. Tab sis rau ntau tus, qhov ci ntawm lub lens yuav qhia ntau heev. Lub lens periscopic muaj qhov zoo tshaj plaws uas nws tau muab zais rau hauv lub cev ntawm lub cuab yeej, thiab yog li ntawd tsis ua rau cov kev xav tau ntawm cov thickness ntawm optics. Tab sis nws kuj muaj ib qho tsis zoo, uas yog qhov tsis zoo ntawm lub teeb pom kev zoo.
Apple sim tawm tsam nws qhov kev sib tw kom txog rau thaum 2015, thaum nws qhia lub iPhone 6S, piv txwv li nws thawj iPhone nrog lub koob yees duab 12MPx. Thiab txawm tias lwm tus tau sim nce tus lej no tas li, Apple ua raws li nws lub tswv yim. Txawm hais tias qhov no tuaj yeem hloov pauv nrog iPhone 14 (lub koob yees duab dav dav yuav tsum yog 48 MPx), txawm tias rau xyoo tom qab tso tawm ntawm iPhone 6S, lub tuam txhab nthuav tawm iPhone 13 series, uas tau nruab nrog 12 MPx lub koob yees duab.

Kev yees duab yog hais txog lub teeb
Apple tsis tau nce qhov kev daws teeb meem, thiab hloov pauv cov sensors lawv tus kheej thiab lawv cov pixels, yog li ua tiav cov duab zoo dua ntawm tus nqi ntawm lawv qhov loj me. Txawm tias tus lej aperture nws tus kheej, uas yog siv los qhia qhov ci, tau txhim kho. Tus nqi brightness txiav txim siab npaum li cas lub teeb poob ntawm lub sensor. Yog li qhov siab dua qhov aperture (yog li tus lej qis dua nws tus kheej), qhov tsis kam muaj tsawg dua rau lub teeb hla lub lens. Qhov tshwm sim yog cov duab zoo dua hauv cov teeb pom kev tsis zoo.
Thiab qhov no yog qhov uas peb tau mus rau qhov teeb meem nrog periscope lo ntsiab muag. Yog lawm, piv txwv li, qhov tshiab tam sim no nyob rau hauv daim ntawv ntawm Samsung Galaxy S22 Ultra yuav muab 10x zoom, txawm tias iPhone 13 Pro tsuas muaj 3x zoom, tab sis nws kuj muaj qhov aperture ntawm f/4,9. Qhov no txhais tau tias tsis muaj dab tsi ntau tshaj li qhov koj tsuas yog siv nws hauv cov teeb pom kev zoo nkaus xwb. Raws li lub teeb txo qis, qhov zoo ntawm qhov tshwm sim yuav txo qis sai. Tsis yog lub f/2,8 aperture ntawm iPhone 13 Pro lub telephoto lens yog qhov zoo tagnrho. Vim tias qhov tshwm sim yuav yooj yim raug kev txom nyem los ntawm lub suab nrov. Lub koob yees duab periscope siv lub kaw lus ntawm prismatic tsom iav ua ke nrog cov lo ntsiab muag, qhov twg lub teeb xav tau tsuas yog "poob" vim tias nws tsis yog tsuas yog xav txog 90 degrees, tab sis kuj yuav tsum tau mus ntev dua.

Peb puas yuav pom ntau dua optical zoom?
Thiab ib yam li Apple tseem tsis tau qhia cov xov tooj foldable tsis tau vim tias lawv tsis ntseeg cov thev naus laus zis, peb tsis txawm muaj lub lens periscopic hauv iPhones. Cov lus teb rau lo lus nug ntawm yog vim li cas peb tsis muaj "periscope" nyob rau hauv lub iPhone tsis tau yog qhov yooj yim heev. Cov thev naus laus zis yog qhov nthuav, tab sis nws txoj kev siv tseem lag luam. Thiab Apple tsuas yog xav muab qhov zoo tshaj plaws xwb. Tsis tas li ntawd, qhov sib txawv yog tias lub koob yees duab telephoto tsis yog qhov tseem ceeb, uas yog vim li cas nws tseem ntxiv lub lens ultra-wide-angle rau cov koob tseem ceeb yam tsis muaj Pro epithet.
