Umdlalo we-Lumens
Uma ucabangela ukuthengwa kweprojekti yevidiyo, mhlawumbe incazelo ecacile kakhulu oyaziyo yilezi zinombolo. I-Lumens isilinganiso sokukhanya okungakanani kweprojekti yevidiyo okungakhipha. Yiqiniso, njengamanye okushiwo, uma umkhiqizi ehlinzeka inombolo yenombolo ye-lumens, kufanele uqaphele njengoba kungekho nhlobo edingekayo ukuze isetshenziswe - ngakho ukulinganiswa kwe-Lumens esetshenzisiwe esetshenziswa umkhiqizo owodwa weprojekthi kungase kube okufanayo njengenye brand. Kodwa-ke, uma ukulinganisa kwezimpawu kukhulunywa ngokwemibono ye-ANSI lumens, lokho kuyizinga elivamile lembonini elingaguquki uma kuqhathaniswa nemikhiqizo emibili futhi bobabili basebenzisa i-ANSI njenge-reference yabo.
Ukukhanya Okumhlophe Okukhanyayo Nokukhanya Kwebala
Kodwa-ke, kuningi okumele ucatshangelwe ngokwemibandela ukuthi ukukhanya kwevidiyo kungenziwa kanjani. Uma ukulinganisa okukodwa kubalulwe, lokho okushiwo yi-White Light Output (WLO) noma i-White Brightness, iphrofayli iyakwazi ukukhiqiza, hhayi ukukhiqizwa kokukhanya okuphelele uma umbala ucatshangelwa. Isibonelo, amaprosesa amabili angaba nesilinganiso esifanayo se-WLO, kodwa ukukhishwa kokukhanya kombala (CLO), noma ukukhanya kweMbala, kungase kuhluke.
Ukuqhathanisa nge-Side-by-Side
Ukuze ufanise umehluko phakathi kweBlack and Color Brightness, isithombe esivela ngenhla sibonisa ukubonisa ohlangothini ngehlangothini lomphumela wombala ekukhanyeni kwevidyo yeprojekti, noma ukukhanya, okukhiphayo. Bobabili amaprosesa esithombeni banokukhishwa okufanayo kwe-White Brightness kodwa bahluke ngokulingana kobugqama bombala abangayenza.
Isizathu sokuthi kukhona umehluko ekukhanyeni koMbala kulabo abakhiqizi ababili ukuthi iphrojekti ngakwesobunxele isebenzisa umklamo we-1-chip DLP (Optoma GT750E), ngenkathi iphrojekitha ngakwesokudla isetshenziswe umklamo we-3LCD (i-Epson PowerLight Home Cinema 750HD). Bobabili amaprosesa anesinqumo esifanayo sokubonisa isizwe ( 720p ) kanye ne-ANSI lumens WLO ethi: 3,000. Isilinganiso esiphakamisiwe sokuhlukanisa i-Optoma singama-3,000: 1 futhi i-Epson ichazwa ngokuthi "kufika ku-" 5,000: 1.
Noma kunjalo, njengoba ubona, iphrojekitha ngakwesokudla ibonakala inembala, imibala ekhudlwana, kanye nokukhanya okuphelele, kuneprojekti ngakwesobunxele.
Indlela Umklamo we-Technology Project owenza ngayo Ukukhanya koMbala
Isizathu sokuba umehluko empeleni izithombe ezibonisiwe, ozibona esithombeni, zihlobene ngokuqondile nomklamo wephrojekithi ezimbili. Umklamo we- 3LCD uvumela wonke ukukhanya okumhlophe nombala ukuthi kudlule i-lens ngokuqhubekayo, isilinganiso sokulinganisa nokulingana kokubili Ukukhanya Okumhlophe nokuMbala. Noma kunjalo, kudizayini ye- 1-Chip DLP , ukukhanya kufanele kuhambe ngesondo lombala elikhanyayo elihlukaniswe ngezigaba ezibomvu, eziluhlaza neziluhlaza okwesibhakabhaka.
Esikhathini sesistimu ye-1-chip DLP, imibala ilandelwa ngokulandelana (ngamanye amazwi, iso lakho alitholi ulwazi lombala ngokuqhubekayo), okungabangela ukukhishwa okukhanyayo kombala ophansi, ngokuphathelene nomkhiqizo omhlophe wokukhanya. Ukuze uhlawulele lokhu, ama-1-chip i-DLP projekthi aphindaphindiwe ngezingxenye eziningi ezimhlophe ukufaka isondo esimhlophe ukuze akhulise Ngenkathi Ubumhlophe, kodwa iqiniso lihlala lide ukuthi izinga lokuBhanya kweMbala lingaphansi kweBright White.
Lo mshwana uvame ukushiwo ngumkhiqizi ekucacisweni kweprojekti. Okuvame ukubonwa yi-single Lumens yokushicilelwa okukhiphayo, kunalokho kungabhala okushiwo yizimpawu ezimbili, enye ye-WLO (i-White Light Output) neyodwa ye-CLO (i-Color Light Output), enika iphrofayli enembile kakhulu ye-Color Brightness iprojekti ingaveza.
Ngakolunye uhlangothi, abaxhasi be-3LCD basebenzisa umhlangano wesibuko / i-prism (akukho sondo lombala elihambayo) ngokuhambisana ne-chip ehlukile yombala ngamunye oyinhloko (obomvu, ukuhaha, okwesibhakabhaka), ngakho kokubili umhlophe nombala kufinyelela iso lakho. Lokhu kubangela ukukhanya okuMhlophe nokuMbala okuqhubekayo.
Njengomphumela oqondile wobuchwepheshe obusetshenziselwa ukukhipha izithombe kusuka kwiprojekitha ngayinye esetshenziswe esithombeni esingenhla, iprojekti ye-1-chip DLP ngakwesobunxele ukukhiqiza ukukhanya okuningi koMbala njengeprojekti ye-3LCD ngakwesokudla, kudinga ukuba nokuningi ukukhanya okuphezulu kwe-White Light okukhipha iphrinta ngakwesokudla - lokhu kusho ukuthi iphrojekthi ye-1-chip ye-DLP iyodingeka isebenzise isibani esiphezulu, nokukhuphuka kokusetshenziswa kwamandla.
Ukuthatha Okokugcina - Kungani Ukukhanya Kokubala Kubalulekile
Njengoba ungabona ngesibonelo sezithombe phezulu kwekhasi, ukukhanya kombala kunomthelela oqondile kulokho okubonayo esibukweni. Lokhu kungabaluleke kakhulu hhayi nje kuphela ekubukeni kwethala lokubuka ekhaya, kepha ekubukeni emakamelweni lapho ukukhanya okukhanya khona kungahle kube khona ukulawulwa kalula, ukubukwa kwe-3D, lapho ukulahleka kokukhanya lapho kubheka izibuko ze-3D kuyisici, futhi kulabo abasebenzisa i-video projectors emfundweni, ibhizinisi, kufaka phakathi ukuhamba, lapho iprojekti ingasetshenziswa khona emakamelo ahlukahlukene lapho ukulawulwa ukukhanya kungaziwa khona ngaphambi kwesandla.
Futhi, ukukhanya kombala okwandisiwe nakho kwandisa umbono wemininingwane ngaphakathi kwesithombe, kungakhathaliseki ukuthi isinqumo sesiboniso. Okuwukuphela kwento engakwazi ukuhlupheka uma ukukhanya kombala kwanda izinga lokulinganisa jikelele. Noma kunjalo, kunezinye izici zokucubungula ividiyo ezingathinta lo mphumela.
Ukuze uthole imininingwane eyengeziwe kwi-Standard Brightness Standard, bheka kuNgqikithi Osemthethweni kanye neBlue Brightness Standard White Paper.
Futhi, ukuqhathanisa ukucaciswa kombala weBluetooth ukukhetha ama-video projectors, hlola Ikhasi Lokuqhathanisa Lokukhipha Umbala Wembala.
Ukuze uthole kabanzi mayelana ne-Lumens ne-Brightness, nokuthi ukukhiqizwa kwevidiyo ye-projector ukukhanya kuhlobene kanjani nokukhishwa kwe-TV, bhekani esihlokweni sethu somngane: Ama- Nits, Lumens, nokuBhanya - Amaphrosesa we-TV vs Vidéo .
