Uzame kangaki ukuqopha ividiyo edlalwa esikrinini sakho se-LED ngefoni noma ikhamera yakho, ukuze uthole kuphela leyo migqa ecasulayo ekuvimbela ukuthi uqophe ividiyo ngendlela efanele?
Muva nje, sivame ukuba namakhasimende asibuza mayelana nezinga lokuvuselela isikrini esiholayo, iningi labo elezidingo zokuqopha, njengezithombe ze-XR ezibonakalayo, njll. Ngithanda ukuthatha leli thuba ngikhulume ngalolu daba Ukuze ngiphendule umbuzo wokuthi yini umehluko phakathi kwezinga eliphezulu lokuvuselela kanye nezinga lokuvuselela eliphansi.
Umehluko Phakathi Kwezinga Lokuvuselela Nezinga Lozimele
Izilinganiso zokuvuselela zivame ukudida, futhi zingadideka kalula namazinga ozimele wevidiyo (i-FPS noma amafreyimu ngomzuzwana wevidiyo)
Izinga lokuvuselela kanye nezinga lozimele kuyafana kakhulu. Womabili amele izinombolo zezikhathi lapho isithombe esimile siboniswa ngomzuzwana. Kodwa umehluko ukuthi izinga lokuvuselela limele isignali yevidiyo noma isibonisi kuyilapho izinga lozimele limelela okuqukethwe ngokwako.
Izinga lokuvuselela lesikrini se-LED linani lezikhathi ngomzuzwana lapho ihadiwe yesikrini se-LED edonsa ngayo idatha. Lokhu kuhlukile esilinganisweni sezinga lozimele kulokho izinga lokuvuselelaIzikrini ze-LEDkufaka phakathi umdwebo ophindaphindiwe wozimele abafanayo, kuyilapho izinga lozimele likala ukuthi umthombo wevidiyo ungaphakela kangaki uhlaka lwedatha entsha kusibonisi.
Izinga lozimele bevidiyo ngokuvamile lingamafreyimu angu-24, 25 noma angu-30 ngomzuzwana, futhi inqobo nje uma lingaphezulu kwamafreyimu angu-24 ngomzuzwana, ngokuvamile libhekwa njengelibushelelezi ngeso lomuntu. Ngokuthuthuka kwakamuva kwezobuchwepheshe, abantu manje sebengabuka ividiyo nge-120 fps kumabhayisikobho, kumakhompyutha, ngisho nakomakhalekhukhwini, ngakho abantu manje basebenzisa amanani ozimele aphezulu ukushutha ividiyo.
Amazinga aphansi okuvuselela isikrini avame ukwenza abasebenzisi bakhathale futhi ashiye umbono omubi wesithombe somkhiqizo wakho.
Ngakho-ke, Lisho Ukuthini Isilinganiso Sokuvuselela?
Izinga lokuvuselela lingahlukaniswa ngokwesilinganiso sokuvuselela esiqondile kanye nezinga lokuvuselela elivundlile. Izinga lokuvuselela isikrini ngokuvamile libhekisela esilinganisweni sokuvuselela esiqondile, okungukuthi, inani lezikhathi lapho i-electronic beam iskena ngokuphindaphindiwe isithombe esikrinini se-LED.
Ngokwemibandela evamile, inombolo yezikhathi lapho isikrini sokubonisa se-LED sidweba kabusha isithombe ngomzuzwana. Izinga lokuvuselela isikrini likalwa nge-Hertz, ngokuvamile efushaniswa ngokuthi “Hz”. Isibonelo, isilinganiso sokuvuselela isikrini esingu-1920Hz sisho ukuthi isithombe sivuselelwa izikhathi ezingu-1920 ngomzuzwana owodwa.
Umehluko Phakathi Kwezinga Lokuvuselela Okuphezulu Nezinga Lokuvuselela Eliphansi
Lapho isikrini sivuselelwa izikhathi eziningi, kulapho izithombe ziba bushelelezi ngokuya ngokunikezwa kokunyakaza kanye nokunciphisa ukucwayiza.
Okubona odongeni lwevidiyo ye-LED empeleni kuyizithombe eziningi ezahlukene lapho uphumule, futhi ukunyakaza okubonayo kungenxa yokuthi isibonisi se-LED sivuselelwa njalo, sikunikeza ukukhohlisa kokunyakaza kwemvelo.
Ngenxa yokuthi iso lomuntu linomphumela wokuhlala obonakalayo, isithombe esilandelayo silandela esedlule ngaphambi nje kokuba umbono osebuchosheni ufiphele, futhi ngenxa yokuthi lezi zithombe zihluke kancane, izithombe ezimile ziyaxhuma zenze ukunyakaza okubushelelezi, okungokwemvelo inqobo nje uma isikrini siqabuleka ngokushesha ngokwanele.
Izinga eliphezulu lokuvuselela isikrini liyisiqinisekiso sezithombe zekhwalithi ephezulu kanye nokudlalwa kwevidiyo okushelelayo, okukusiza ukuthi uxhumane kangcono nemikhiqizo yakho nemilayezo yomkhiqizo kubasebenzisi obaqondisayo futhi ubahlabe umxhwele.
Ngokuphambene, uma izinga lokuvuselela isibonisi liphansi, ukudluliswa kwesithombe sesibonisi se-LED kuzoba okuphambene nemvelo. Kuzophinde kube khona "imigqa yokuskena emnyama", izithombe ezidabukile nezilandelanayo, kanye "nama-mosaic" noma "ghosting" aboniswe ngemibala ehlukene. Umthelela wayo ngaphezu kwevidiyo, ukuthwebula izithombe, kodwa futhi ngenxa yokuthi amashumi ezinkulungwane zamalambu akhanyayo izithombe ngesikhathi esifanayo, iso lomuntu lingase likhiqize ukungakhululeki lapho libuka, futhi libangele nokulimala kwamehlo.
Amazinga aphansi okuvuselela isikrini avame ukwenza abasebenzisi bakhathale futhi ashiye umbono omubi wesithombe somkhiqizo wakho.
Ingabe Izinga Lokuvuselela Eliphezulu Lingcono Ezikrinini ze-LED?
Izinga eliphezulu lokuvuselela isikrini likutshela amandla ezingxenyekazi zekhompuyutha zesikrini ukukhiqiza kabusha okuqukethwe kwesikrini izikhathi ezimbalwa ngesekhondi. Ivumela ukunyakaza kwezithombe ukuthi kushelele futhi kuhlanzeke kuvidiyo, ikakhulukazi ezigcawini ezimnyama lapho kukhombisa ukunyakaza okusheshayo. Ngaphandle kwalokho, isikrini esinezinga eliphezulu lokuvuselela sizofaneleka kangcono okuqukethwe ngenani elibaluleke kakhulu lozimele ngomzuzwana.
Imvamisa, izinga lokuvuselela elingu-1920Hz lilungele iningiIzibonisi ze-LED. Futhi uma isibonisi se-LED sidinga ukubonisa ividiyo yesenzo sejubane eliphezulu, noma uma isibonisi se-LED sizoshuthwa ikhamera, isibonisi se-LED sidinga ukuba nenani lokuvuselela elingaphezu kuka-2550Hz.
Imvamisa yokuvuselela isuselwa ekukhetheni okuhlukile kwama-chips omshayeli. Uma usebenzisa i-chip yomshayeli evamile, izinga lokuvuselela lombala ogcwele ngu-960Hz, futhi izinga lokuvuselela lombala owodwa nokabili ngu-480Hz. uma usebenzisa i-chip yomshayeli ebamba kabili, izinga lokuvuselela lingaphezulu kuka-1920Hz. Uma usebenzisa i-chip yomshayeli yeleveli ephezulu ye-PWM ye-HD, izinga lokuvuselela lifika ku-3840Hz noma ngaphezulu.
I-chip yomshayeli we-PWM yezinga eliphezulu le-HD, ≥ 3840Hz izinga lokuvuselela led, isibonisi sesikrini sizinzile futhi sishelela, akukho ripple, akukho ukunensa, akukho umuzwa wokucwayiza okubukwayo, hhayi kuphela ukujabulela isikrini esiholelekile, kanye nokuvikelwa ngempumelelo kokubona.
Ekusetshenzisweni kochwepheshe, kubalulekile ukunikeza izinga lokuvuselela eliphezulu kakhulu. Lokhu kubaluleke kakhulu ezigcawini ezihloselwe ukuzijabulisa, imidiya, imicimbi yezemidlalo, ukuthwebula izithombe okubonakalayo, njll. ezidinga ukuthwetshulwa futhi zizorekhodwa ngevidiyo amakhamera ochwepheshe. Izinga lokuvuselela elivunyelaniswa nefrikhwensi yokurekhoda yekhamera lizokwenza isithombe sibukeke siphelele futhi sivikele ukucwayiza. Amakhamera ethu aqopha ividiyo ngokuvamile ku-24, 25,30 noma 60fps futhi sidinga ukuyigcina ivunyelaniswa nezinga lokuvuselela isikrini njengokuphindaphinda. Uma sivumelanisa isikhathi sokuqoshwa kwekhamera nesikhathi sokushintsha kwesithombe, singagwema umugqa omnyama wokushintsha kwesikrini.
Umehluko Wezinga Lokuvuselela Phakathi Kwezikrini ze-LED ezingu-3840Hz kanye Nezi-1920Hz.
Ngokuvamile, izinga lokuvuselela elingu-1920Hz, iso lomuntu kube nzima ukuzwa ukucwayiza, ngokukhangisa, ukubukwa kwevidiyo kwanele.
Izinga lokuqabuleka kwesibonisi se-LED elingekho ngaphansi kuka-3840Hz, ikhamera yokuthwebula ukuzinza kwesikrini sesithombe, ingaxazulula ngempumelelo isithombe senqubo yokunyakaza esheshayo yokulandela nokufiphala, ithuthukise ukucaca nokugqama kwesithombe, ukuze isikrini sevidiyo sintekenteke futhi bushelelezi, ukubuka isikhathi eside akulula ukukhathala; ngobuchwepheshe bokulungisa obumelene ne-gamma kanye nobuchwepheshe bokulungisa ukukhanya kwephoyinti nephuzu, ukuze isithombe esiguqukayo sibonise izinto ezingokoqobo nezemvelo, ezifanayo futhi ezingaguquki.
Ngakho-ke, ngentuthuko eqhubekayo, ngikholwa ukuthi izinga lokuvuselela elijwayelekile lesikrini esiqondisiwe lizoshintshela ku-3840Hz noma ngaphezulu, bese libe izinga lemboni kanye nokucaciswa kwalo.
Vele, izinga lokuvuselela le-3840Hz lizobiza kakhulu ngokwezindleko, singenza ukukhetha okunengqondo ngokuya ngesimo sokusetshenziswa nesabelomali.
Isiphetho
Kungakhathaliseki ukuthi ufuna ukusebenzisa isikrini se-LED sangaphakathi noma sangaphandle sokukhangisa, ukwethula amavidiyo, ukusakaza, noma ukuqopha okubonakalayo, kufanele njalo ukhethe isikrini sokubonisa se-LED esinikeza izinga eliphezulu lokuvuselela isikrini futhi esivumelanisa nezinga lozimele elirekhodwe ikhamera yakho uma ufuna ukuthola izithombe ezisezingeni eliphezulu esikrinini, ngoba ngaleso sikhathi umdwebo uzobukeka ucacile futhi uphelele.
