Tshiab video txheem: 4K-daws teeb meem. Lub tshuab 4K-resolution - yog dab tsi?

Niaj hnub no, yuav luag txhua txhua hnub koj yuav pom los sis hnov xws lo lus ob peb ua ke raws li 4K-daws teeb meem. Coob leej ntau tus assents, hais tias, yog, nws yog txias! Ib txhia xav, yog vim li cas yog nws tsim nyog? Thiab thaum ib tug khoom ib feem ntawm cov pejxeem tsis paub dab tsi nws yog tag nrho hais txog. Cia saib qhov kev txiav txim thiab muab tag nrho rau lub rhawv, yog li ntawd sawv daws yuav to taub li cas yog lub tswvyim ntawm "4K daws teeb meem".

Ib me ntsis keeb kwm

Nyob rau lub xyoo pua 21st - technology mus deb ua ntej piv rau nag hmo tav su, thiab yog hais tias peb pog thiab yawg thiab niam txiv tseem nco ntsoov lub hnub thaum movies (raws li tau zoo raws li ntau lwm yam ntaub ntawv) muab cia rau hauv lub nqus films, cov tam sim no tiam, thiab paub txog nws nws tsis paub dab tsi. Niaj hnub no, lub loj heev reels tau sunk rau hauv oblivion, muab txoj kev rau cov cia thiab kis tau tus mob tawm tswv yim. Suab thiab yees duab tapes nrog ib tug sib nqus zaj duab xis yog maj hloov los ntawm CDs, thiab lawv, nyob rau hauv lem, yog tseem pib mus tawm ntawm cov haiv neeg, dua cov baton mus rau ib tug USB-drives los yog high-ceev zog disks SSD. Qhov ntau technology npaj, qhov ntau nws yuav peb "hnab tshos" cia xov xwm ... Thaum Bill Geyts txib hais tias "640 kilobytes txaus rau txhua leej txhua tus rau txhua tus xav tau." Suab funny, tsis yog nws? Niaj hnub no txawm ntau MMS lus los yog ringtones rau cov xov tooj txhua txhua 5-6 tshaj no loj. Niaj hnub no lub smartphones muaj peev xwm nqa ib tug 128 gigabytes ntawm cov ntaub ntawv (thiab ib txhia txawm xav paub ntxiv) hnab tshos "stick" kom tau roj yooj yim 250-500 gigabytes, thiab ib lub tsev computer calmly yuav khaws mus txog rau ib tug thiab ib tug ib nrab rau ob terabytes ntawm cov ntaub ntawv. Thiab ib zaug neeg zoo siab yuav ib tug hard disk ntawm 40 GB, thiab xav tias nws yog tib yam rau tag nrho cov lub ntshai heev ntau li ntau! Tab sis tsis muaj dab tsi sawv tseem. Lub deb, lub steeper. Nug seb hnub no yuav siv sij hawm ntau npaum li ntawd qhov chaw? Daws teeb meem, comrades, yog kev daws teeb meem.

Yuav ua li cas yog nws?

Daws teeb meem - lub xov tooj ntawm dots nyob rau hauv lub ntsug thiab kab rov tav. Suab zoo li ib yam dab tsi paub daws teeb, tsis yog nws? Thiab sim mus saib nyob rau lub desktop daws teeb meem ntawm koj saib (tsev los yog chaw ua hauj lwm). Nyob rau hauv qhov tseeb, qhov no yog lub thawv, uas qhia txog lub Desired ntaub ntawv uas koj muab rau koj, seb nws yog ib daim duab los yog ib feem ntawm nws, ib daim ntawm no tsab xov xwm los yog video. Thiab thaum lub duab plaub, qhov ntau xis peb tau perceive ntaub ntawv. Nws yog tsis tsim nyog mus saib mus rau hauv lub ntsiab txhais ntawm lub thav duab nyob rau hauv cov yeeb yam, tsis tas yuav mus sub los ntawm qhov sib txawv lub sij hawm hauv tsab xov xwm hauv qab no los yog mus rau sab, tsis tas yuav xav npaum li cas tus nas mus nias rau qhov daim duab mus saib zoo nkaus li zoo li no los yog tias kev nthuav dav. Thiab ua tas mus li "muaj peev xwm" kev daws rau peb saib los yog TVs, tib neeg tau tuaj mus rau ib lub teeb meem: yog hais tias qhov luaj li cas ntawm ib daim duab los yog cov yeeb yam yog tsawg tshaj li cov zaub daws teeb meem, cov duab pib ncab, thiab qhov chaw - lubricated, deform. Roughly hais lus, cov duab yuav distorted. Pom zoo, ib tug me ntsis qab ntxiag mus rau xam tau tias yog ib tug nyiam tsev neeg yees duab, qhov twg tag nrho cov neeg yuav tsum tau nyob rau hauv thawv los yog nkos thiab ncav us txog.

Thiab nyob rau tej teeb meem raws li lub sij hawm thiab nws tau txiav txim rau kom tus thawj zaug loj ntawm cov duab, duab los yog movies. Maj mam daws teeb meem cov ntxaij vab tshaus ua ntau thiab ntau, ua raws li los ntawm nce ob lub luaj li cas thiab zoo ntawm cov ntaub ntawv tso tawm. Khoos phib tawj ua si kuj tsis sawv ib cag, vim hais tias cov developers sim ua kom lub virtual ntiaj teb no zoo li ib tug kev muaj tiag. Raws li, ncauj lus kom ntxaws dluab tsim (txawm futuristic) loj hlob sai sai li lub clarity ntawm cov yeeb yaj duab thiab cov duab. Tsis ntev cov koob yees duab pib coj cov duab nyob rau hauv megapixel koob yees duab, video camera mus tua kawm kawm nyob rau hauv siab daws teeb meem, thiab ua si lub computer tau txais ib tug ntau ntau tiag graphics. Tab sis tau txais kev pab yuav tsis tau txaus - nws xav mus saib cov lus qhia ntxiv nyob rau hauv ib zaug. Thiab ces, mus rau lub twb uas twb muaj lawm thiab ntev-qub rau txhua leej txhua tus daim di ncauj, lub tswv yim ntawm HD thiab FullHD duab-screen, muab lub 4K daws teeb meem. Cia peb xav txog lub tswvyim.

Lub tshuab 4K-resolution - yog dab tsi?

Niaj hnub nimno ntau screen muaj peev xwm displaying ntaub ntawv nyob rau hauv lub HD hom ntawv los yog FullHD. Tus thawj hom (High Lus Txhais) muaj cov nram qab yam ntxwv: ntsug daim duab feem ntau muaj 720 dots (pixels). Yuav kom daws tau FullHD (Full High Lus Txhais) tus naj npawb ntawm pixels mas zus mus txog 1020. Tus kab rov tav pixel tooj rau cov ob hom feem ntau xwm yeem mus rau favorites ua ntej lub nam ratio (16: 9 los yog 16:10, nws yog suav tias yog ntau Dav). Tab sis, raws li cov neeg xav ntau thiab ntau "cov mov thiab cov circuses", lub chaw tsim tshuaj paus tau ploj mus ib kauj ruam ntxiv thiab tsim ib tug tshiab zaub hom muaj ib tug daws teeb meem ntawm 4K screen. Nyob rau hauv cov txheej txheem no lub hloov dua siab tshiab ntawm pixels nyob rau hauv no embodiment tau hloov lawm. Tam sim no tus xov tooj ntawm pixels displayed rau qhov kev tshuaj ntsuam, yog tsis yog nyob rau hauv lub ntsug (raws li nyob rau hauv HD thiab FullHD), thiab horizontally, thiab yog hais txog 4000. Hais kom ib tug 4K daws teeb meem muaj nyob rau hauv cov ntaub ntawv no? Cov yam li daim duab yuav ua tau raws li nram no: 3840x2160 pixels. Nws yog hais tias qhov no technology enables mus tso saib nyob rau ntawm qhov kev tshuaj ntsuam yog hais txog 4 lub sij hawm ntau ntaub ntawv dua thaum FullHD hom (uas txog thaum tsis ntev los no tau pom tias raws li cov kev siv).

raws li muaj peev xwm

Ntawm cov hoob kawm, tam sim ntawd nyob rau hauv lub muag khoom ntawm TV nrog 4K daws teeb meem.
