Indlela yokukhetha isikrini seprojektha

Isikrini sokubonisa indawo eyisicaba noma egobile ehlakazekayo lapho kwakhiwa khona isithombe esikhulisiwe sefreyimu yefilimu, isilayidi, isithombe, njll. usebenzisa i-projektha. Kukhona izikrini ezikhanyayo nezidlulisela ukukhanya.

Izikrini ezibonisayo babe nesisekelo esikhanyayo, sibonisa kahle ukukhanya okugeleza okuwela kuzo cishe ngokulinganayo kuzo zonke izinhlangothi ngaphakathi kwe-engeli engu-180 °. Isithombe esikubo siyabukwa kusukela ohlangothini lwe ama-projection amathuluzi. Izikrini ezinjalo zifakwe kuwo wonke ama-cinema, ngaphandle kwama-cinema asemini, lapho amafilimu aboniswa khona esikrinini sokudlulisa ukukhanya. Ingaphezulu lezikrini ezikhanyayo, njengomthetho, zimhlophe-matte.

Izikrini ezidlulisa ukukhanya zenziwe ngengilazi eqhwa, ipulasitiki ekhanyayo noma indwangu ehlanganiswe nefilimu. Badlulisela imisebe yokukhanya kahle, cishe ngaphandle kokuyibonakalisa. Isithombe esikubo siyabukwa kusukela ohlangothini oluphambene kuya idivayisi yokubonisa. Namuhla zisetshenziswa, ngaphezu kwe-cinema yasemini, ekufakweni kokukhangisa kanye nemibukiso.

Ukubonisa esikrinini esidlulisa ukukhanya. Ikhulu le-19

Uhlobo lweskrini

Okomile ukufakwa, izikrini ezifakwe odongeni noma ezifakwe kusilingi ziyasetshenziswa. Uma kufanele Ukuthutha isikrini ukusuka kwelinye igumbi ukuya kwelinye, futhi uhambe naso emibukisweni yangaphandle, udinga ukuthenga esinye sezikrini zeselula.

Izikrini ze ukufakwa umile ziyagoqwa noma zeluliwe (ohlakeni). Izikrini zokugoqa zingagoqwa futhi zembulwe, izikrini ezicindezelayo, njengoba negama lisho, zelulelwe kuhlaka olukhethekile (ezifakwe kukhithi), futhi zihlala zithatha indawo yazo odongeni. Lokhu kukhetha, njengomthetho, kunqunywa ukuklama nezici zokusebenza zekamelo.

isikrini sokushuba

Ngaphezu kwalokho, Roll -Izikrini zeprojektha zingalayishwa entwasahlobo noma zenziwe ngemoto. Izikrini ze-roll ezilayishwe entwasahlobo ziyi ukuqaqa ngesandla futhi yagoqwa ngomthombo. Izikrini ezihamba ngemoto ziyaphakanyiswa futhi zehliswe nge- imoto kagesi . Izikrini ezinemoto ngokuvamile ziza namaswishi anentambo, kodwa isilawuli kude siyatholakala njengenketho.

Izikrini zeselula ziyahlukahluka ngohlobo lokwakhiwa nokufakwa. Kukhona izikrini zedeskithophu, kanye nezinhlobo ezimbalwa zemiklamo yesikrini saphansi. Okudume kakhulu ngokwentengo kanye nokusebenza kukhona izikrini ezintathu . Agoqa kalula futhi ngokushesha futhi anesisindo esincane. Izikrini zangempela ezihoxiswayo ezindlini eziphansi zizothakasela wena ngokuyinhloko ngesisindo sazo esilula, ukufakwa kalula, kanye nomklamo omuhle kakhulu.

Isikrini esingaphezulu

Abakhiqizi besikrini besimanje banikeza izinhlobo ezahlukene zezindawo ezihloselwe ukuxazulula inkinga eyodwa: ukudlulisa okuphezulu kakhulu izinga isithombe kusibukeli. Isikrini sokubonisa singenza umsebenzi owodwa noma eminingi elandelayo: sikhulise ukugqama kwesithombe, sikhulise ukugqama kwaso, futhi sivumele ukukhanya kudlule ngaphandle kokubonisa ukukhanya kwangaphandle. Nokho, udinga ukukhetha surface ngokucophelela kakhulu , uma kungenjalo ingxenye yezethameli, futhi ngezinye izikhathi ngisho nazo zonke izibukeli, ngeke zibone isithombe.

Okokuqala, ake sigxile ezicini eziyinhloko zendawo:
1. Ukuzuza – inani elihlobene elibonisa ikhono lesikrini ukukhombisa ukukhanya okuwela kuso. Uma iphezulu, isithombe sizobonakala kubabukeli.
2. Qhathanisa - ikhono lokukhiqiza ngokunembile izindawo ezimnyama nezikhanyayo zesithombe.
3. I-engeli yokubuka ibonisa isikhala lapho ababukeli bengabona khona isithombe ngokukhululeka.

Isixazululo esijwayelekile esizodlulisela isithombe kunoma yisiphi isibukeli yi-a ubuso obumhlophe be-matte , eqokwe abakhiqizi njengo-Matte White (S, M, P), M1300, Panamax. Indawo enjalo ine-engeli enkulu yokubuka kanye nokukhiqizwa kombala okunembile. Inzuzo yale canvas ingu-1, okungukuthi ayikukhulisi ukugqama kwesithombe, kodwa nayo ayinciphisi.

Kuya thuthukisa ukukhanya , kunezinhlobo ezimbili zezindawo: ezikhanyayo (Datalux MFS, Pearlscent) kanye nobuso obunobuhlalu (HighPower, Glass Beaded). Ukuzuza kwezindawo ezinjalo kuyahlukahluka kusuka ku-2 kuye ku-2.5. Kusetshenziswa indawo yokuqala lapho iprojektha ifakwe ophahleni , ngoba ikhombisa ohlangothini oluphambene nesigameko semisebe. Ikhava yobuhlalu (ikhava ye-glass chip) ikhombisa ngasemthonjeni wokukhanya futhi ingasetshenziswa kuphela uma iprojektha ifakiwe the izinga elifanayo nezethameli, isibonelo, phezu kwetafula eliphambi kwesikrini. Kufanele futhi kucatshangelwe ukuthi izindawo ezicwebezelayo zine-engeli elinganiselwe yokubuka, futhi ababukeli abahlezi kude nendawo ephakathi kwesikrini bangase bangasiboni isithombe. Lezi zindawo ezingaphezulu zisetshenziswa emakamelweni anokukhanya okukhanyayo okuzungezile, kanye namaphrojektha anokukhishwa kokukhanya okuphansi.

Indawo empunga (Ukugqama Okuphezulu, i-HiDef Grey) isetshenziselwa ukwenza kanjalo thuthukisa ukugqama . Lezi zindawo ezingaphezulu zinenzuzo engu-0.8-0.9 kanye ne-engeli enkulu yokubuka. Ikhono lokunikeza okumnyama okujulile ngaphandle kokufaka engozini amathoni okukhanya nokumhlophe lilungele ukunikeza noma yiluphi uhlobo lwesithombe esiyingcaca. Le ndawo engaphezulu idume kakhulu ekwakhiweni kwamathiyetha asekhaya.

Isimo se-Screen

Le parameter iyona isilinganiso sobubanzi be isithombe esinezithombe ubude baso. Imishini eminingi yokuqagela yokubuka imuvi yasekhaya iza nesikrini sokubukeka kwesilinganiso esingu-9:16. Ngenkathi enguqulweni yehhovisi ifomethi yesikrini efaneleka kakhulu ingu-3:4. Kuya ngcono izinga wesithombe sevidiyo, kuyadingeka ukuqinisekisa ukuthi usayizi wekhanvasi ufana nefomethi yesithombe ngokwaso esithunyelwa yiprojektha.

Uma ukhetha uhlobo lwesikrini olungalungile, wena angabona umnyama amabha kungaba ngezansi noma emaceleni esithombe.

Izikrini ze-projection zavela kudala ngaphambi kokufika kwamaphrojekhtha wevidiyo - ngisho nasekuqaleni kokuzalwa kwe-cinema. Futhi lokhu kwaholela ezinhlobonhlobo ezinjalo zesilinganiso sezinhlangothi zabo.

• Ifomethi yesikwele 1:1 . Ifomethi eguquguqukayo ekuvumela ukuthi ukhiqize izithombe ezivundlile neziqondile. Amaslayidi ezithombe aboniswe ezikrinini ezinjalo, afakwe kumafreyimu ayisikwele.
• Ifomethi yesithombe 3:2 (1.5:1) . Njengoba igama lisho, ifomethi yesikrini ihambisana nefomethi yefreyimu yesithombe evamile.
• Ifomethi yevidiyo 4:3 (1.33:1) . Ifomethi yozimele we-TV yencazelo evamile SD I-TV.
• Ububanzi 16:9 (1.78:1) . Ifomethi entsha ye-TV enencazelo ephezulu HD I-TV.
• Isikrini esibanzi esingu-1.85:1 sokubukeka kwesilinganiselo . Ifomethi evamile yamafilimu afakiwe.
• Ukubukeka kwesilinganiselo sesinema 2.35:1 . Ifomethi ebanzi kakhulu ku-cinema, ibanzi kuphela kumasinema we-panoramic.

Mayelana nevidiyo Ukuqagela, kunengqondo ukukhuluma ngamafomethi amathathu kuphela - 1:1, 4:3 kanye ne-16:9. Uma sidinga isikrini kuphela dlala ividiyo ejwayelekile , SD or HD , bese kusale ukukhetha phakathi kwamafomethi 4:3 kanye 16:9.

Ochwepheshe besitolo "Umfundi" batusa ifomethi engu-4:3 njenge eguquguqukayo kakhulu . Esikrinini sokubukeka kwesilinganiso esingu-4:3, ungahlala ubonisa isithombe sokubukeka kwe-16:9 ngokugcwalisa ububanzi besikrini. Futhi uma unesikrini esigoqekayo, singanwetshwa ngendlela efanayo kakhulu njengoba kudingeka ukudlala ifomethi ethile.

Izilungiselelo zegumbi nesakhiwo sesikrini

Isikrini kukhethwe kahle ngendlela yokuthi noma yimuphi umuntu okhona ekamelweni akwazi ukuhlaziya imibhalo nezithombe ngokukhululeka esikrinini. Ukuze ubale usayizi wekhanvasi yesikrini, kunconywa ukuthi uqondiswe yimithetho emithathu eyisisekelo:

• Ubude besikrini kufanele bube okungenani 1/6 yebanga ukuya kumugqa wokugcina wezihlalo egumbini
• Ibanga kusukela phansi kuya emaphethelweni aphansi Isikrini kufanele okungenani sibe ngu-125 cm
• Umugqa wokuqala wezihlalo kufanele ube ku okungenani kabili ukuphakama kwesikrini
