Niaj hnub no, nws tsis yog qhov txawv txav los hla cov smartphones nrog ntau dua 100 MPx. Tshwj xeeb, Samsung cov xov tooj ntawm tes nrog Ultra moniker tau muaj lub koob yees duab 108MPx rau qee lub sijhawm tam sim no. Tsis tas li ntawd, cov koob yees duab nrog cov kev daws teeb meem siab no ncav cuag cov chav nruab nrab. E.g. Samsung nws tus kheej tau teeb tsa nws hauv Galaxy A73. Txawm li cas los xij, cov xov tooj no tseem thaij duab 12MP los ntawm lub neej ntawd. Tab sis yog vim li cas yog li ntawd?
Dab tsi yog qhov tseem ceeb ntawm tag nrho cov megapixels thaum lub koob yees duab tseem thaij duab qhov nruab nrab? Nws tsis yog qhov nyuaj rau kev txiav txim siab. Cov koob yees duab digital sensors npog nrog ntau txhiab thiab ntau txhiab lub teeb pom kev me me, lossis pixels. Kev daws teeb meem siab dua txhais tau tias ntau pixels ntawm lub sensor, thiab ntau pixels uas haum rau tib lub cev ntawm lub sensor, qhov me me cov pixels yuav tsum yog. Vim tias cov pixels me me muaj thaj tsam me me, lawv tsis tuaj yeem khaws lub teeb ntau npaum li cov pixels loj dua, uas txhais tau tias lawv ua haujlwm tsis zoo thaum lub teeb qis.

pixel binning
Tab sis lub koob yees duab lub xov tooj siab megapixel feem ntau siv cov txheej txheem hu ua pixel binning kom tau txais qhov teeb meem no. Nws yog ib qho teeb meem technical, tab sis cov kab hauv qab yog qhov ntawd Galaxy Lub S22 Ultra (thiab tej zaum yuav yog A73 yav tom ntej) muab cov pab pawg ntawm cuaj pixels.

Tsis tas li ntawd, nws zoo li nws yuav succumb rau qhov no thiab Apple. Txog tam sim no, nws tau ua raws li nruj 12 MPx lub tswv yim nrog qhov loj ntawm lub sensor thiab yog li tus neeg pixels. Txawm li cas los xij, iPhone 14 yuav tsum tuaj nrog lub koob yees duab 48 MPx, uas yuav cia li sib koom ua ke 4 pixels rau hauv ib qho thiab yog li cov duab 12 MPx yuav raug tsim dua. Tshwj tsis yog tias koj yog tus kws yees duab tshaj lij tshaj lij thiab tsis xav luam koj cov duab hauv hom loj, nws yuav luag ib txwm tsim nyog tawm ntawm kev sib koom ua ke thiab tua ntawm qhov tshwm sim 12 MPx.

Nyob rau hauv lub teeb zoo dua, nws txhim kho sum los ntawm folding.
Yog lawm, cov digital zoom yog mus txog 100x. Txawm li cas los xij, nws txoj kev siv yog qee qhov teeb meem.
100x yog qhov tseeb, tab sis txhua yam ntawm 1x thiab 3x yog qhov zoo dua nyob rau hauv lub teeb zoo ua tsaug rau qhov loj sensor nrog ntau mpix. Hauv qhov tsis zoo, qhov zoo dua ploj mus…
