Ukuze kuzuzwe ukuboniswa kwencazelo ephezulu, kufanele kube nezinto ezine: eyodwa ukuthi umthombo wevidiyo udinga ukuchazwa okuphezulu okugcwele;okwesibili ukuthi isibonisi esiholayo kufanele sisekele ukuchazwa okuphezulu okugcwele;okwesithathu ukunciphisa ukuphakama kwephikseli yesibonisi esiholayo;okwesine inhlanganisela yesibonisi esiholayo kanye nephrosesa yevidiyo.Njengamanje, isibonisi esinombala ogcwele naso siya ekubonisweni kwencazelo ephezulu.
1. Thuthukisa umehluko weisibonisi esinombala ogcwele.Ukugqama kungenye yezinto ezibalulekile ezithinta umphumela wokubuka.Ngokuvamile, uma umehluko uphezulu, isithombe sicaca futhi umbala ucace kakhulu.Ukugqama okuphezulu kusiza kakhulu ekucaciseni isithombe, ukusebenza kwemininingwane, kanye nokusebenza kwezinga elimpunga.Kwezinye izibonisi zombhalo nevidiyo ezinokugqama okukhulu okumnyama nokumhlophe, izibonisi ezinombala ogcwele ezinomehluko ophezulu zinezinzuzo ngokugqama okumnyama nokumhlophe, ukucaca, nobuqotho.Ukugqama kunomthelela omkhulu kumthelela wokuboniswa kwevidiyo oguquguqukayo.Ngenxa yokuthi ukuguquka kokukhanya-okumnyama esithombeni esiguquguqukayo kuyashesha, lapho umehluko uphezulu, kuba lula emehlweni abantu ukuhlukanisa inqubo enjalo yokuguqula.Eqinisweni, ukuthuthukiswa kokugqama kwesikrini esinombala ogcwele ngokuyinhloko ukukhulisa ukugqama kwesibonisi esinombala ogcwele kanye nokunciphisa ukubonakala kwesikrini.Kodwa-ke, ukukhanya akukona okuphakeme ngangokunokwenzeka, kuphezulu kakhulu, kuzoba okuphambene, ngeke nje kuthinte impilo yesikrini esibonisiwe esiholelekile, kodwa futhi kubangele ukungcoliswa kokukhanya.Ukungcoliswa kokukhanya sekuphenduke isihloko esishisayo manje, ukukhanya okuphezulu kakhulu kuzoba nomthelela emvelweni nakubantu.Amaphaneli aholayo wesibonisi esinombala ogcwele kanye namashubhu akhipha ukukhanya okune-led acutshungulwa okukhethekile, okunganciphisa ukubukeka kwephaneli eholayo futhi kukhulise ukugqama kwesibonisi esinombala ogcwele.
2. Thuthukisa izinga elimpunga lesibonisi esinombala ogcwele.Ileveli empunga isho ileveli yokukhanya engahlukaniswa kusukela kokumnyama kakhulu kuye kokugqama kakhulu ekugqameni kombala owodwa oyinhloko wesikrini esiholayo.Lapho izinga elimpunga liphakeme lesibonisi esinombala ogcwele, umbala ucebile kanye nombala ocwebe kakhulu;ngokuphambene, umbala wokubonisa awuwodwa futhi ushintsho lulula.Ukukhuphuka kwezinga elimpunga kungakhuphula kakhulu ukujula kombala, kwenze izinga lokubonisa lombala wesithombe likhule ngokwejometri.Ileveli yokulawula isikali esimpunga ngu-14bit~16bit, okwenza imininingwane yeleveli yesithombe nemithelela yokubonisa yemikhiqizo yesibonisi esiphezulu ifinyelele ezingeni eliphezulu lomhlaba.Ngokuthuthuka kobuchwepheshe behadiwe, isikali esimpunga sizoqhubeka sithuthukela ekunembeni okuphezulu.
3. Yehlisa ukuphakama kwe-pixel yeisibonisi esiholayo.Ukunciphisa ukuphakama kwephikseli kwesikrini esinombala ogcwele kungathuthukisa ukucaca kwaso.Uma kuncane ukuphakama kwephikseli kwesibonisi esinombala ogcwele, yilapho isibonisi sesikrini esiholelekile sithambile.Kodwa-ke, ubuchwepheshe obuvuthiwe kumele kube yibo obusekela lokhu.Izindleko zokufakwayo ziphezulu uma kuqhathaniswa, futhi intengo yesibonisi esinombala ogcwele okhiqizwayo nayo iphezulu.Ngenhlanhla, imakethe manje iya phambiliisibonisi esihle sephikseli ye-pitch LED.
4. Inhlanganisela yesibonisi esinombala ogcwele nephrosesa yevidiyo.Iphrosesa yevidiyo eholayo ingasebenzisa ama-algorithms athuthukile ukuze iguqule isiginali ngekhwalithi yesithombe ephansi, ithuthukise imininingwane yesithombe, futhi ithuthukise ikhwalithi yesithombe.I-algorithm yokukala yesithombe yephrosesa yevidiyo isetshenziselwa ukuqinisekisa ukuthi ukucijile kanye nezinga elimpunga lesithombe kugcinwa ngokwezinga elikhulu kakhulu ngemva kokuba isithombe sevidiyo sikaliwe.Ngaphezu kwalokho, iphrosesa yevidiyo nayo iyadingeka ukuthi ibe nenqwaba yezinketho zokulungiswa kwesithombe kanye nemiphumela yokulungisa ukuze kucutshungulwe ukukhanya kwesithombe, ukugqama, kanye nesikali esimpunga ukuze kuqinisekiswe ukuthi isikrini sikhipha isithombe esithambile nesicacile.
