Isixazululo se-4k se-Ultra HD – incazelo, okuhle nokubi, yimalini ngamaphikseli

Ukulungiswa kuyisici esibalulekile se-TV nevidiyo. Isho isibalo samaphikseli ngendawo evundlile neqondile. Lapho ukulungiswa kuphezulu, kucaca ngokwengeziwe, kunemininingwane eminingi yesithombe esithathwe ocingweni. Abakhiqizi be-TV banqunyelwe ekuboniseni izinombolo ezivundlile. Isibonelo, ukulungiswa kwe-4k kubhekisela ekuxazululeni kwe-cinema yedijithali kanye nehluzo zekhompyutha. Ihambisana namaphikseli angu-4000 ngokuvundlile.

Isixazululo esingu-4k – incazelo yezinga

Ukukhathazeka kwaseJapan i-NHK ithuthukise indinganiso ye-UHDTV yomkhakha wezokuxhumana. Yamukelwa ngo-2012 phakathi nemihlangano yeNyunyana Yezokuxhumana Yomhlaba. Ukulungiswa okuphezulu bekungamaphikseli angu-3840×2160. Yaziwa ngokuthi yi-Ultra HD. Izikrini ze-TV zikwazile ukuthola i-aspect ratio yesikrini esibanzi. Yalingana nendawo engu-16:9. Namuhla, leli zinga lingelinye elivame ukuhlangana futhi lithengwe. Embonini yefilimu, ibizwa nge-4K ngoba ububanzi bohlaka lohlaka sebuphenduke amaphikseli angu-4000. Kuyathakazelisa ukuthi abakhiqizi bethelevishini abacabangi ukumisa lapho. [i-id yamagama-ncazo = “okunamathiselwe_2731” align = “aligncenter” wide = “669”]
Izinqumo ezijwayelekile[/caption] Ukuze uqonde ividiyo enencazelo ephezulu kakhulu, udinga ukucabanga ngesikrini esingamamitha angu-15. Isithombe esikuyo sizohlala sinokucaca okufanayo nesesikrinini sikamabonakude esijwayelekile. Iprojektha yesinema yedijithali isekela kuphela ukulungiswa okungu-2k. Ukusekelwa kwefomethi ye-quad kuku-IMAX. Kuhunyushwe kusukela kusiNgisi sokumaketha, lolu uhlobo oluphezulu lwesithombe. Ngokwezinga elijwayelekile, kusetshenziswa amaphrojektha amaningana anesixazululo esiphindwe kane. I-4k isho ukucaca okuphelele nemininingwane yesithombe, esidluliswa ngokukhanyayo futhi esigcwele. Ukuminyana ngobuqiniso besithombe kukhula ngenxa yokwehliswa kosayizi wamaphikseli kanye nokwanda kwenani lawo. Ngenxa yalokho, izinto ziba nemininingwane eminingi kuhlaka futhi zingabukwa kangcono. Uma kuqhathaniswa no-2k, i-4k inikeza izinga lozimele elithuthukisiwe, ukujula kombala kanye nekhwalithi yomsindo. I-UHD isebenza izinga lozimele. Umbala unokujula kwamabhithi ayi-12, futhi ukumbozwa kombala kungu-75%. Isikrini sikhiqiza amathunzi angaba ngu-69,000,000,000 wephalethi yombala. Ukuze uthole ukuqonda okungcono, amamodeli aphezulu e-Full HD ashintsha ozimele ngesivinini esingamakhilogremu angu-60. Umbala unamabhithi angu-8, futhi isikhala sombala sivala isikrini ngo-35%.

Umehluko phakathi kwesinqumo se-4K ne-2K

Ama-HDTV abe indinganiso esetshenziswa amashumi eminyaka. Namuhla, awekho amadivaysi kamabonakude angabonisi ukulungiswa kwe-720p. “P” imele uhlobo lwesithombe esiqhubekayo. Ngiyindlela ehlukile, ephawulwe nge-interlaced. Imigqa eyinqaba nelinganayo iboniswa ngokushintshana kuhlaka ngalunye. Lokhu kubangela ikhwalithi yesithombe eyehlisiwe. Igama elithi 4000 pixels liyifomethi yokubonisa enokulungiswa okuvundlile okubanzi. I-UHD ingu-4k. Umehluko wukuthi ifaneleka kakhulu kubathengi nakumabonakude nge-2k. Ngenxa yalokho, i-DCI ithathwa njengezinga lokukhiqiza elisezingeni eliphezulu, elilinganiselwe ngamaphikseli angu-4096 x 2160. I-UHD iyindinganiso enokulungiswa kwamaphikseli angu-3840 x 2160. Kukhona ifomethi engu-8k kumaphikseli angu-7620 x 4320. Inikeza isithombe esingenasici.

Ubuhle nobubi bokulungiswa kwe-4k uma kusetshenziswa kuma-TV

Ukulungiswa kwe-4k kuletha imininingwane yesithombe ecace ngokukhuphula ukuminyana kwe-pixel ngemilimitha yesikwele sesikrini ngasinye. Izinga lokushanela amafreyimu angu-120 ngesekhondi. Isithombe esinjalo esishukumisayo sinikeza ukucindezelwa okuncane emehlweni, ikakhulukazi uma umuntu ebuka ithelevishini isikhathi eside nangehora. Ukulungiswa kwe-4k kukhiqiza uhla lwemibala ejulile, ecebile. Ithuthukisa ukucaca kwesithombe kuzo zombili izindawo ezikhanyayo nezimnyama zesikrini. Ifomethi inikeza ikhwalithi yomsindo engcono kakhulu. Inzuzo engangabazeki yomsebenzisi yama-Ultra HD TV amaqiniso alandelayo:

1. Ifomethi ingasetshenziselwa imidlalo yevidiyo yesikrini esibanzi, amatrices ekhompyutha; Isikrini sikucwilisa eqinisweni elibonakalayo ngaphandle kwezibuko ezikhethekile.
2. I-matrix yakha uhlobo lwesithombe esinezinhlangothi ezintathu umbukeli esihlolayo kunoma yisiphi isikhathi; nge-stereo awudingi izibuko.
3. I-TV ingabukelwa kude, lokhu kungenxa yokwanda okuphindwe kane kwesithombe sesikrini.

Inzuzo umzuzu wokuthi kungenzeka kubekwe i-TV efulethini elincane elinendawo enesizotha yamakamelo.

Ububi obuyinhloko besinqumo se-4k yisidingo esandayo sekhwalithi yesignali. Lokhu kuholela kokuqukethwe okulinganiselwe okudluliselwa ngekhwalithi esetshenzisiwe. Kunamamuvi akhethekile nemibukiso ku-YouTube engasetshenziswa kumamodeli angu-4k. Ku-Netflix kunamafilimu anochungechunge anokubhaliswa okukhokhelwayo, okumba eqolo. I-Megogo inokuqukethwe okuningi kwencazelo ephezulu.

Imaphi ama-TV asebenzisa i-4k

Ukulungiswa kwe-4K kungenye yekhwalithi ephezulu kakhulu futhi ecace kakhulu. Ngenxa yalokho, ungabuka izinhlelo ze-TV ngokucaca okwengeziwe. Inzuzo yalesi sinqumo iwukungafani okuphezulu nemininingwane yesithombe, okwenza umphumela we-3D ngaphandle kokusebenzisa izibuko ezikhethekile. Namuhla, ukulungiswa kwe-4K kuyatholakala kumamodeli e-TV alandelayo: i-Xiaomi Mi TV 4S65 T2S 65, LG 43UM7020 43, Samsung UE43TU8000U, Samsung UN78KS9800, LG 43UK6200, LG 50UN73506LB, BBK 46C21UTS / UE43TU8000U. Kuyafaneleka ukuveza ukuthi wonke ama-TV anesinqumo se-4k anesistimu “ehlakaniphile” eyenza kube nokwenzeka ukubuka okuqukethwe kwevidiyo, okuqukethwe kwesithombe nokusebenzisa i-intanethi, izinhlelo zokusebenza nemidlalo. Ngenxa yokubambisana okuqondile kwabathuthukisi bezinga nabakhiqizi, umthengi, ekugcineni, uthola ukufinyelela kokuqukethwe okungcono kakhulu. Ibhonasi yabasebenzisi ukufinyelela kufomethi yekhwalithi yamafilimu ngesikhathi esifanayo lapho asakazwa khona kumasinema. Ukuze uqonde kangcono amandla e-4k TVs, izimo ezithile kufanele kuhlangatshezwane nazo. Idivayisi kumele ibe ne-diagonal ebanzi. Kufanele ibe nokusakaza kwe-TV eyakhelwe ngaphakathi kwe-4k ngokusakazwa kwedatha yevidiyo etholakalayo. Ekugcineni, umuntu uzothola bukhoma ngesithombe esinezinhlangothi ezintathu, lapho imibala idluliselwa khona enamanzi, ngokwemvelo. [i-id yamagama-ncazo = “okunamathiselwe_2323” align = “aligncenter” wide = “511”] Kufanele ibe nokusakaza kwe-TV eyakhelwe ngaphakathi kwe-4k ngokusakazwa kwedatha yevidiyo etholakalayo.

Ukulungiswa kwe-2K, i-HD, i-hd ephelele, i-UHD, i-4K ne-8K – umehluko

Ithelevishini enencazelo ephezulu noma i-HD iyindinganiso esetshenziswa iminyaka eyi-15 yonke indawo. Isho ukulungiswa kwamaphikseli angu-720p noma angu-1280×720. Nokho, ama-TV angu-90% emakethe namuhla asekela i-Full HD. Lokhu kusho ukuthi iveza amaphikseli angu-1080p noma angu-1920×1080. “R” – okuqhubekayo ekuhumusheni kusuka kusiNgisi. Kusho ukuthi isithombe sohlaka ngalunye silandelana. Umugqa ngamunye wohlaka udwetshwe ngokuningiliziwe. Elinye igama elithi “R” lithi “i”. Imele ukuskena okuxhumene. Lokhu kusezingeni le-HDTV ku-1080i. Okungajwayelekile nemigqa elinganayo iboniswa ngokulandelana kuhlaka ngalunye. Lokhu kuholela ekuwohlokeni okuphawulekayo kwekhwalithi yesithombe. I-UHD noma i-Ultra HD iyindinganiso efana ne-4K. Okuhlukile ukuthi inikeza inombolo encane yamachashazi – amachashazi angu-3840×2160 (2K). I-4K ilandela izinga le-2K, eyakhiwe yi-DCI futhi inikeza ukulungiswa okuthuthukisiwe izikhathi ezimbalwa. I-4k, i-Ultra High-Definition noma i-Ultra High Definition – ikhono ledivayisi lokukhipha izithombe kumamonitha anama-TV namaphrojektha. Lokhu ukulungiswa kwevidiyo ngesifinyezo noma esinye isithombe.
Kukhona nefomethi ye-Full HD Ultra. Ivamise ukubizwa nge-8K, inesixazululo samaphikseli angu-7620 x 4320. Kunama-TV amaningi analo pharamitha ku-inthanethi namuhla. Nokho, ukuze ukwazise, ​​udinga i-diagonal engu-85 amayintshi ku-TV. Izinzuzo zamafomethi zibonakala ebangeni elihlukile lomsebenzisi ukusuka esikrinini (ene-diagonal engamayintshi angama-20 kuye kwayi-130). Ebangeni elingamamitha ayi-12, zonke izindinganiso zibukeka zifana. Ebangeni elingafika kumamitha ayi-10, izinzuzo ze-720p ziyabonakala, ebangeni elingamamitha angama-7.5 – 1080p, futhi ebangeni elingamamitha angama-5 – 4k. Isimo sawo wonke amazinga siyefana: i-diagonal ye-TV isuka ku-50 kuya ku-140 amayintshi. Uma kungenjalo, akunakwenzeka ukuhlola izinzuzo. Uyini umehluko phakathi kokulungiswa kwe-2K, 4K, 8K ngezinombolo namaphikseli: https://youtu.be/cUWkH_qV5Lg
