Iithelevishini ngekhono lokudlulisela umfanekiso wesithathu namhlanje ziya kuthi zithandwa. Esi siphumo siphumelelwe ngoncedo lobuchwepheshe obukhethekileyo, xa amehlo amabini ebona umboniso owodwa, kodwa avela kwimibono eyahlukileyo. Ngenxa yoko, uphawu ludluliselwa kwingqondo kwaye umntu ubona umfanekiso wesithathu.
Indlela yokukhetha i-3d ye-TV edibanisayo?
Ngaphambi kokuba unqume ukukhetha iTV ye-3d ekhokelwayo, misela indawo egumbini kuye. Inyaniso kukuba yonke imizekelo yamabonwakude anamhlanje ayenzelwe umgama othile ukusuka kwisikrini ukuya kumbukeli. Ukulinganisa lo mda, kuba kuya kufuneka ukhethe ukudibanisa kwe-TV ye-3d kunye nale mpawu. Eyona mkhulu umgama, ukudibanisa ngakumbi unokukwazi ukufikelela. Emva koko ugqibe isigqibo esiphila kakhulu kuwe: 720p okanye 1080r. Ngoku ihlala kuphela ukubala ukudibanisa: ukuba isisombululo ngo 720p phinda umgama nge-2.3, kunye nesisombululo 1080p i-coefficient ngu-1.56.
Indlela yokukhetha i-TV ehamba phambili ye-3d: inzuzo kunye nokungahleleki kwemodeli
Inketho eqhelekileyo kukuba kufezekiswe umphumo omathathu ngoncedo lweziglasi ezikhethekileyo. Kukho iintlobo ezintathu eziphambili.
- Teknoloji yeAnaglyph. Oku kuyona ndlela encinci. Ukusuka kuwe ufuna kuphela ukubeka ngokufanelekileyo iifayile zokukhanya kwaye uqinisekise ukuba umbala weglasi uhambelana nombala we-stereophiles. Kule nto yonke into eyenzeka ngenxa yokuhlunga umbala. Ukungalungi kukubukeka kombala ombi kunye nokukhathala kwamehlo okugqithiseleyo, oku kunokukhokelela kwisifo somlenze omile kunye nokusetyenziswa rhoqo. Kwakhona u-anaglyph "ukwesaba" kwe-video compression, ngoko kuya kufuneka uhlale ukhetha iifayile eziphezulu.
- Iiglasi zeLCD ezisebenzayo. Le teknoloji ibandakanya ukusetyenziswa kokuvalwa okusebenzayo usebenzisa i-crystals yamanzi kunye nezihlunu zokwenza i-polarization. Ngesibili ukuvalwa kuvulwe kwaye kuvalwa ubuncinane ngamaxesha angama-120, kunye neliso ngalinye libona kuphela loo nxalenye yomfanekiso ojoliswe kuyo.
Lo mzekelo weglasi ukuvumela ukuba ukhethe i-TV ye-3d ngesiboniso esincinci, kuba ayifuni utshintsho olubalulekileyo kuyilo. - Iingongoma usebenzisa indlela yokwenza i-polarization. Le khetho onokuyibona kwiidememzi zesixeko. Iilensi kule modeli ziquka iiglasi ezilula kunye nezihlunu zokuhlutha. Ukuba ukhangele uhlahlo lwabiwo-mali kunye nekhwalithi, kufuneka ukhethe i-TV ye-3d eneziglasi ezingapheliyo, kuba iindleko zazo ziphantsi kakhulu kunomzekelo osebenzayo kwaye ukuguqulelwa kombala kulungile. Kwakhona, iziglasi ezinjalo azibaniki i-aura okanye i-flicker effect xa ibonwa.
