Key Takeaways
- Xiaomi Mi 11 muaj lub ntsej muag 108 megapixel sensor hauv nws lub koob yees duab loj.
- Txawm tias nws lub vijtsam tseem muaj qhov tshwj xeeb zoo dua li cov khoos phis tawj siab-kawg saib-ntawm ntawv.
- Qhov downsides ntawm ntau pixels tshaj qhov zoo.
Xiaomi tus tshiab Mi 11 lub xov tooj smartphone ntim cov tsis txaus ntseeg 108 megapixels rau nws lub koob yees duab me me, uas yog ntau dua Fujifilm tus tshiab $ 6,000 GFX100S. Tab sis vim li cas? Ib yam yog tseeb. Nws yuav tsis ua kom cov duab zoo dua.
Lub Mi 11 lub xov tooj smartphone, muaj thawj zaug sab nraud Suav teb, zoo li tsim los tsuas yog qhia tawm qee qhov tsis txaus ntseeg dhau qhov kev qhia tshwj xeeb, suav nrog lub koob yees duab. Tab sis dab tsi yog lub ntsiab lus? Koj tuaj yeem ua luam ntawv loj los ntawm lub sensor, tab sis leej twg luam tawm cov duab ntxiv lawm? Thiab tsis muaj downsides los siv xws li ib tug ntom sensor nyob rau hauv ib lub xov tooj?
"Tsis muaj laj thawj rau lub xov tooj kom muaj 108MP lub koob yees duab," tus kws yees duab vaj tsev Matthew Digati hais rau Lifewire ntawm email.
"Hauv kuv txoj haujlwm tshaj lij, kuv siv lub koob yees duab nrog 24MP. Tsuas yog vim li cas koj thiaj li xav tau lub koob yees duab 108MP yog tias koj tab tom npaj yuav tsim cov ntawv loj loj. ib lub tsev."
Zoo siab heev
Yog tias koj tab tom ua cov npe ntawm cov lus qhia tshwj xeeb, ces Mi 11 yuav yog tag nrho ntawm lawv. Lub 6.81-nti AMOLED npo muaj 120Hz refresh npaum li cas (ob npaug ntawm iPhone 12), nrog rau 3, 200 x 1, 440 daws teeb meem. Cov zaub txhawb nqa 10-ntsis xim, uas feem ntau tsuas yog pom hauv cov khoos phis tawj zoo saib.
Muaj ntau qhov kev sib tw hauv kev ntim khoom uas ntau megapixels rau hauv qhov ntsuas me me.
Nws tseem ci, nrog lub teeb pom kev siab tshaj plaws ntawm 1, 500 nits. Rau cov ntsiab lus, Apple's $ 6,000 Pro Display XDR muaj qhov tso zis siab tshaj plaws ntawm 1, 600 nits.
Tab sis tom qab ntawd peb mus rau lub koob yees duab. Lub koob yees duab selfie ib leeg ntim 20MP, ultra-wide muaj 13MP, thiab lub xov tooj muaj tsuas yog 5MP. Tab sis qhov xwm txheej tseem ceeb yog thawj lub koob yees duab, uas siv qhov tsis txaus ntseeg 108MP. Tab sis vim li cas thiaj phem?
Ntau npaum li cas?
Hauv qab no yog cov vis dis aus los ntawm kws yees duab thiab kws qhia Kevin Raposo uas piv 108-megapixel lub koob yees duab hauv Samsung's Galaxy S21 Ultra nrog tus kws tshaj lij DSLR.
Muaj qee qhov zoo rau kev suav pixel siab. Ib qho peb tau hais dhau los - lub peev xwm los ua cov ntawv loj.
Lwm tus yog "downsampling," qhov twg cov ntaub ntawv los ntawm ob peb lub pixels uas nyob ib sab muab piv thiab ua ke ua kom me me, tab sis cov duab huv dua. Qhov no feem ntau yog cov xov tooj siab megapixel ua. Nws kuj tso cai rau koj txiav cov duab, thiab tseem muaj cov duab uas zoo nkaus li zoo ntawm Instagram.
Tab sis cov sensors hauv cov koob yees duab me me, thiab ntim rau tag nrho cov pixels muaj nqi.
"Tsis yog lub koob yees duab 108MP nkaus xwb tsis tsim nyog, tab sis nws los nrog qee qhov teeb meem loj ib yam," Digati hais. "Tus nqi ntawm lub cim xeeb thiab ua lub zog xav tau los ntes thiab khaws 108MP daim duab yog qhov loj heev."
"Muaj ntau qhov kev sib tw hauv kev ntim ntau megapixels rau hauv qhov ntsuas me me," tus kws yees duab Niklas Rasmussen hais rau Lifewire ntawm email. "Vim qhov ntsuas qhov loj me, txhua pixel yuav tsum me me heev. Qhov ntawd ua rau lawv tsis tshua pom lub teeb, uas tuaj yeem ua kom muaj suab nrov ntau rau hauv daim duab."
Dab tsi ntxiv, feem ntau ntawm qhov zoo ntawm cov pixel suav siab tuaj yeem pom tau zoo ib yam nrog tus lej qis dua. Txawm tias muaj lub koob yees duab tseem ceeb lub sensor ntawm "tsuas yog" 54MP tseem yuav tso cai rau downsampling, cropping, thiab ua cov prints loj.
Yog tias koj saib Raposo cov yeeb yaj kiab, saum toj no, ces koj yuav pom lwm yam. Qhia ntawm lub vijtsam, Canon 1DX MkII cov duab tsis zoo dua li cov ntawm Galaxy S21 Ultra. Pom qhov loj dua, ntawm lub saib loj lossis luam tawm, cov duab Canon yeej yooj yim.
Tab sis ntawm qhov ntau thiab tsawg peb feem ntau saib cov duab-hauv xov tooj thiab ntsiav tshuaj cov ntxaij vab tshaus-lub Galaxy zoo txaus. Qhov ntawd tsis mus rau qhov ntxiv pixels, txawm li cas los xij. Lub iPhone ua rau cov duab zoo nkauj, piv txwv li, nrog nws lub koob yees duab 12MP.
Kev lag luam
Qhov no los rau, ces, yog kev lag luam. Hauv kev lag luam uas txhua lub xov tooj Android zoo sib xws, tshwj xeeb tshaj yog rau cov neeg tsis paub lossis tsis txaus siab rau cov neeg yuav khoom, pov tawm cov lej loj xws li qhov no yog txoj hauv kev zoo rau kev sib txawv ntawm koj cov khoom. Hmoov tsis zoo, nws tsis yog txoj hauv kev zoo los tsim lub koob yees duab zoo dua.
