Yog li, tsuas yog hais txog kev tshaj lij hom tuaj yeem siv tag nrho lub peev xwm ntawm lub lens.
Cov duab thaij duab
Cov duab siv ntau npaum li cas?
sai li sai tau cov iPhones tshiab tau nkag mus rau hauv tes ntawm cov neeg tshuaj xyuas thawj zaug, cov xov xwm hais txog qhov chaw ntau npaum li cas 48Mpx ProRAW cov duab coj mus rau qhov tseeb tam sim ntawd ya ncig hauv Is Taws Nem.

Nws yuav yog txaus siab rau koj
Flying thoob ntiaj teb nrog Apple Cia peb saib ntawm qhov kev sib tw nws tus kheej, uas yog Samsung Galaxy S22 Ultra, uas tam sim no tuaj yeem suav tias yog tus neeg sib tw tseem ceeb ntawm Apple xov tooj tshiab. Lub xov tooj no mus ob peb kauj ruam ntxiv tshaj Apple ntawm cov lej - nws khav theeb lub lens nrog kev daws teeb meem ntawm 108 Mpx.

Kua poob
Ib yam yog pom tseeb los ntawm kev sib piv - Apple poob tam sim ntawd. Txawm hais tias qhov zoo ntawm cov duab yog qhov tseem ceeb tshaj plaws, nws tseem yuav tsum tau coj mus rau hauv tus account nws cov efficiency thiab loj. Nws yog vim li no cov lus nug ntawm yuav ua li cas Apple yuav daws qhov no hauv qhov kawg thiab peb tuaj yeem xav li cas los ntawm nws yav tom ntej. Koj puas xav tias qhov luaj li cas ntawm 48Mpx ProRAW cov duab ua lub luag haujlwm tseem ceeb, lossis koj puas kam saib qhov mob no hais txog qhov zoo ntawm cov duab?
Kuv tsis nkag siab qhov uas tus sau ntawm tsab xov xwm xav tias Apple poob. Thaj, qhov no tshwm sim los ntawm nws ignorance thiab naivety. Yog tias kuv xav tau cov ntaub ntawv ntau npaum li qhov ua tau hauv daim duab, ces tej zaum kuv yuav tsis txaus siab tias cov chaw tsim khoom compressed nws mus rau qhov me me, yog tias compression tsis khaws 100% ntawm cov ntaub ntawv. Tus neeg sau tsab xov xwm puas tuaj yeem suav tias qhov loj npaum li cas cov ntaub ntawv yuav tsum yog?
Lukáš, tab sis tseem muaj kev daws teeb meem siab dua nrog tsawg cia hauv nco.
Dab tsi yog qhov tshwm sim ntawm cov lus hais saum toj no? Yuav ua li cas ntxiv los piav qhia qhov kev daws teeb meem siab dua nrog qhov me me ntawm cov ntaub ntawv tshwm sim dua li compression, piv txwv li qhov "poob" ntawm qee cov ntaub ntawv? Tau kawg, peb tseem muaj txoj hauv kev xws li deduplication, tab sis peb tab tom tham txog kev sib txuas ntau cov duab.
Raws nraim. Tsis tas li ntawd, qhov kho qhov muag tsis tuaj yeem hloov kho, thiab lub lens me me tsuas tuaj yeem ua tiav qhov kev daws teeb meem. Yog tias nws ua tau, cov tuam ntxhab ntawm cov khoom siv yees duab yuav tsis siv cov lo ntsiab muag kim kim thiab cov chips sensor loj
Lukáš, nws zoo li koj ignorance... Tseem muaj lossless compressions uas tsis cuam tshuam qhov zoo. Tsis tas yuav tiv thaiv Apple thev naus laus zis dhau los thiab saib cov txiv apples me ntsis thuam ...
Kuv ntseeg tias kev poob qis tsis yog Samsung rooj plaub, yog li qhov tseem ceeb ntawm cov thev naus laus zis no yog qee qhov tawm ntawm qhov chaw. Yog, thiab nws ua raws li cov lus qhia ntws = cov lus teev tom qab L = nyuaj Y ;-)
Nws tsis yog tsuas yog qhov kev daws teeb meem tseem ceeb rau kev kho, tab sis feem ntau yog cov ntaub ntawv ntau, kev daws teeb meem siab thiab cov ntaub ntawv me me = siab compression = duab tsis zoo.
Lub ntsiab lus yog tias Apple tsis tuaj yeem thaij duab hauv tag nrho 48 Mpx daws teeb meem hauv cov qauv qauv nrog compression - nws tsuas tuaj yeem nqa RAW xwb, yog li tus neeg siv yuav tsum ua cov ntawv tshaj tawm nws tus kheej. Hauv qhov sib piv, Samsun kuj tseem siv cov duab hauv kev daws teeb meem 108Mpx hauv cov qauv qauv nrog compression, thiab yog tias tus neeg siv yog tus kws yees duab thiab xav ua tus txheej txheem tom qab nws tus kheej, nws tuaj yeem teeb tsa tias nws xav thaij duab hauv RAW, uas tus sau tsis tau ua. :) zoo, kuv tuaj yeem hais li cas txog qhov ntawd ... hauv kuv lub tswv yim tus qauv apple neeg siv :)
Cov qauv no yog siv los ntawm cov kws yees duab tshaj lij, uas feem ntau yuav tsis muaj iPhone Feem ntau, raws li cov duab muaj kev txhawj xeeb, kuv S22ultra siv cov duab zoo ib yam li iPhone 13 pro max nws. Kuv tsis muaj qhov sib piv nrog lub iPhone tshiab tsis tau ..
Qhov ntawd ua rau muaj kev nkag siab zoo, yuav tus tshiab iP14 Pro rau yuav luag 35K, thiab tom qab ntawd kaw qhov txiaj ntsig tsuas yog nws muaj tshaj qhov pheej yig dua 13 Pro :D Hauv kuv lub tswv yim, iP14PRO yuav tsum tau pib nrog 256GB, ntawm tus nqi ntawd thiab xav txog ntau npaum li cas cov duab. nqa.
Kuv pom ib qho "trick" nyob qhov twg, yuav ua li cas ib tug neeg siv cov duab ntawm 48MPx thiab tom qab ntawd hloov nws mus rau 12MPx ntawm txoj kev luv, tias nws muaj cov ntsiab lus zoo dua yog tias nws thaij duab ncaj qha ntawm 12MPx.
Kuv tau txiav txim siab nws ib pliag, tab sis qhov tseeb yog vim qhov kev ntxub ntxaug tawm dua, thiab sib nrug ntawm 48MPx tsis muaj kev hloov pauv, Kuv nyob nrog 13PRO kom txog thaum Apple zais qhov qias neeg hauv qab cov zaub. Tab sis kuv tsis xav tos ntev, puas yog? Xws li Galaxy ULTRA tsuas yog muaj kev nkag mus uas tsis yog "ua phem", yog li tej zaum kuv yuav ncav cuag Galaxy thaum kawg. Kuv tsis muaj lwm lub khw Apple, tsuas yog iPhone, uas yog kev sib tw nrog Android. Infantile MacOS, uas yog rau cov menyuam yaus thiab iPAD nws tus kheej, tsis tso cai rau hauv kuv qhov barracks. Kuv muaj nws, kuv sim nws, thiab nws yog outdated, infantile, tsuas yog rau " ruam" amateurs ... Kuv twb tsis tham txog AW, tragic durability, zoo li ib tug tamaman, nrog rau cov tshiab ULTRA, uas kuj yog qias neeg thiab nrog lub siab qub... Kuv tau sau ib yam dab tsi. Kuv tab tom muab Apple li ib xyoos, max 2 Kuv tuaj yeem mus txog rau iP16 PRO, tej zaum :D yog tias lawv tsis tshem tawm qhov tsis txaus ntseeg, kuv yuav mus rau lwm qhov.
Koj yog menyuam yaus. Koj tuaj yeem ua tsis muaj dab tsi kiag li. Yog koj ua tau, koj yuav tsis hais lus ruam.
