"Imithetho yegeyimu" ehlukile emakethe yesikrini samamuvi
Ngemakethe yesibonisi ye-LED yesikrini esikhulu, okugxilwe kakhulu komncintiswano "i-dot pitch".Okusho ukuthi, ikhono lokukhiqiza imikhiqizo ethembeke kakhulu enamaphikseli amancane ngendlela eyongayo "iwumugqa oyinhloko wokuncintisana kwezobuchwepheshe"I-LED ibonisa imboni yesikrini esikhulu.
Kodwa-ke, njengoba imakethe yesikrini sefilimu ibuswa ubuchwepheshe be-"projection" iminyaka eyikhulu, ukugxila kokuncintisana kwezobuchwepheshe kule makethe kuwele "ekukhanyeni kwephrojekthi".Ukubonakaliswa okuyinhloko kwezinga lokukhanya kweprojektha kumphumela wesikrini "ukuthi isikrini singavezwa sikhulu kangakanani ngaphansi kokwaneliswa kwekhwalithi yesithombe": Ngakho-ke, isikrini se-movie sinesakhiwo sokuhlinzeka ngezicaciso ezahlukene ezifana namamitha angu-7, 10. amamitha, namamitha angama-20.
Isitifiketi se-DCI siwumphumela wokuqagela wefilimu kanye nezinga lokuvikelwa kwelungelo lobunikazi eliholwa amaqembu okuqukethwe aseHollywood.Nakuba isimo sayo esingokomthetho "siyizinga leqembu lebhizinisi lokuzithandela", iminyaka yokusebenza kwezimakethe zomhlaba ikwenze kwaba indinganiso yokufinyelela embonini ye-de facto "yezikrini zama-movie nezinto zokubonisa" emakethe yamazwe ngamazwe.
Ngakho-ke, uma i-isikrini esikhulu se-LEDifuna ukungena emakethe yetiyetha yamamuvi yamamitha angu-20, kufanele ithole isitifiketi se-DCI sesikrini samamitha angu-20.Ikakhulukazi ngemva kokuba izikrini zesinema ze-LED ezingaphezu kwamamitha angu-10 zithole isitifiketi se-DCI, lesi sitifiketi samamitha angu-20 akuseyona inkinga yobuchwepheshe, kodwa inkinga "yomthetho wemakethe".Njengoba iwumkhiqizo wobuchwepheshe obusha obulandela imithetho emidala, ukubaluleka okukhulu kwesitifiketi esisha se-DCI sesikrini se-LED esingamamitha angu-20 ukuthi silethe ushintsho olukhulu emingceleni yokuncintisana.
Amamitha angu-20 kufanele kube indawo yamanzi "yesikrini se-movie LED"
Sisho ukuthini isikrini se-LED esingamamitha angama-20?Izibukeli zemboni ziveze ukuthi ukuphambana kwentengo phakathi kwezikrini ze-movie ze-LED kanye nemishini yokuqagela ye-DLP iwela cishe ngamamitha angama-20.Okusho ukuthi, nakuba izikrini ze-movie ze-LED ezingaphezu kwamamitha angu-10 zithole isitifiketi se-DCI, zonke ziyimikhiqizo yazo izindleko zayo ziphakeme kakhulu kunalezo zemishini ye-movie ye-projektha yendabuko.
Njengamanje, izikrini ezinkulu ze-LED zingene okokuqala emakethe yesikrini se-movie, futhi kusobala ukuthi akukabi yisikhathi sokuthi zikwazi ukusungula imithetho nemithethonqubo.Ukuqhubeka nokuthobela imithetho yoqobo yomkhiqizo wemakethe yesikrini se-movie ehlongozwayo akusona nje isiqinisekiso somphumela wokudlalwa kwemuvi, kodwa futhi kuyinhlonipho yemikhuba "yamaketango etiyetha" emakethe yangempela.Kule nqubo, izikrini ze-LED ezibonakala zihlukaniswe ngosayizi abangenamkhawulo kumele futhi zamukele ukucaciswa kwesikrini okujwayelekile okufana ne-"10m/20m" ukuze kutholwe isitifiketi sokufinyelela emakethe.
Ingqikithi yemishini yokuqagela inamazinga okukhanya.Isikrini esingamamitha ayi-10 sihambisana nezinga lokukhanya kwezinga lokungena lemishini yokudlala emakethe yasetiyetha, futhi singomunye wemikhiqizo "eyonga kakhulu".Isikrini esingamamitha angu-20 sisho ukuthi ukukhanya kweprojektha kumele kube ngokuphindwe izikhathi ezingu-4 kunokwesikrini samamitha ayi-10: noma ngabe ukugqama kweyunithi eyodwa noma isisombululo se-dual-unit superimposition, ubunzima bobuchwepheshe beprojektha. izokhushulelwa ezingeni eliphezulu.
Uma kuqhathaniswa, kusikrini samamitha angu-20 okuboniswa kwe-4K kwesikrini se-movie ye-LED, imfuneko yobuchwepheshe eyinhloko yenkomba yokuphakama kwe-pixel izophindwa kabili uma iqhathaniswa nesikrini samamitha angu-10 se-4K, futhi ukuminyana kwe-pixel kuzoncishiswa ngo-75%.Nakuba indawo yayo yokuhlanganisa iphinde yenyuka yaba izikhathi ezi-4 kunesikrini esingamamitha ayi-10, ubunzima bobuchwepheshe benkomba yezikhala ezimaphakathi bunciphile, okwenza uguquko lwezindleko lulawuleke.Lokhu kuzokwenza lula ukwakheka kancane kancane kwenzuzo yayo yokuqhathanisa ekuqhudelaneni kwezindleko.
Ngesikhathi esifanayo, ngokombono wabaqhubi be-theater chain, isikrini samamitha angu-10 siyihholo lokuhlola ukonga.Isikrini samamitha angu-20 sigxile kakhulu kumphumela wokushaqisa obonakalayo, ozohambisana nezinzuzo zokukhanya, ukugqama, kanye nombala wesikrini esikhulu se-LED.Ngesikhathi esifanayo, ihholo lesikrini elingamamitha angu-20, elilandela imiphumela eyengeziwe, lizongabizi kakhulu kumathiyetha.Ngaphezu kwezidingo ezihlukene zemiphumela yokuqagela, imishini eminingi yokuqagela ehholo elingamamitha ayi-10 futhi yamukela ukucushwa "kwegumbi lomshini".
Kodwa-ke, imishini ye-projection ehholo elingamamitha angama-20 kufanele ithathe indawo yegumbi lekhompyutha-lokhu kuzosiza izinzuzo zeUmshini wemvelo wesikrini se-LEDisidingo esingaphansi kwegumbi.Ngaphezu kwalokho, izidingo zokusebenza ezihlukene zehholo elingamamitha ayi-10 azikho phezulu njengehholo elingamamitha angama-20: indawo enkulu yesikhala yehholo elingamamitha angama-20 ilivumela ukuthi lithuthukise kangcono imibukiso yezingxoxo, amakhonsathi, nemidlalo ye-e. imicimbi kumodi yokukhanya okuphezulu kwesikrini esikhulu se-LED , indawo yokudlela yamamuvi, ukusakazwa bukhoma kwengqungquthela nezinye izindlela zokusebenza eziningi.
Okusho ukuthi, i-DCI inikeza isitifiketi sesikrini se-movie se-LED esingamamitha ayi-10, okungaphezu kokugunyazwa kobuchwepheshe okungokomfanekiso.Ngoba ehholo lamamitha ayi-10, inzuzo yokuncintisana yezikrini ze-LED icindezelwa yimishini yokuqagela.Kodwa-ke, ngemva kokukhishwa kwesitifiketi se-DCI sesikrini se-movie ye-LED esingamamitha angu-20, kusho ukuthi izikrini zokubonisa kanye ne-LED zingene esimweni sokuncintisana "esikhathazayo" emakethe yama-movie, ngisho nezikrini ze-LED zinenzuzo encane.
Ukufingqa, isitifiketi se-DCI sesikrini samamitha angu-20 sesikrini se-movie ye-LED sibonisa ukuthi lesi sixazululo sokuboniswa kwefilimu entsha "sikhula ngokushesha".Kukholakala ukuthi esikhathini esizayo esiseduze, kuzoba nohlelo oluphelele lwesixazululo sesikrini se-movie ye-LED kusukela ehholo elincane elingamamitha ayi-7 kuya kwesikrini esikhulu se-IMAX.Umlando wekhulunyaka ubudala wokuqagela kochungechunge lwesinema usuzongena esigabeni esisha sokuncintisana nokubambisana kobuchwepheshe obukabili.
