Uzame kangaphi ukurekhoda ividiyo edlalwa kwiscreen sakho se-LED ngefowuni yakho okanye ikhamera, ukuze ufumane loo migca ikruqulayo ikuthintela ekurekhodeni ividiyo ngokufanelekileyo?
Kutshanje, sihlala sinabathengi besibuza malunga nezinga lohlaziyo lwescreen esikhokelwayo, uninzi lwazo zezemfuno zokufota, ezifana ne-XR yokufota, njl njl. Ndingathanda ukuthatha eli thuba lokuthetha ngalo mba Ukuphendula umbuzo wokuba yintoni ngumahluko phakathi kwezinga eliphezulu lokuhlaziya kunye nesantya esisezantsi sokuhlaziya.
Umahluko phakathi kwereyithi yokuhlaziya kunye nenqanaba lesakhelo
Amaxabiso okuhlaziya ahlala ebhidanisa, kwaye anokubhidaniswa ngokulula namazinga esakhelo sevidiyo (iFPS okanye iifreyimu ngesekondi nganye yevidiyo)
Ireyithi yokuhlaziya kunye nesantya sefreyimu ziyafana kakhulu. Zombini zimela amanani amaxesha omfanekiso omileyo oboniswa ngesekhondi. Kodwa umahluko kukuba ireyithi yokuhlaziya imele isignali yevidiyo okanye isibonisi ngelixa ireyithi yesakhelo imele umxholo ngokwawo.
Izinga lokuhlaziya isikrini se-LED linani lamaxesha okwesibini ukuba i-hardware yesikrini se-LED idonsa idatha. Oku kwahlukile kumlinganiselo wesantya sesakhelo kwireyithi yokuhlaziyaIzikrini ze-LEDiquka umzobo ophindaphindiweyo wezakhelo ezifanayo, ngelixa izinga lesakhelo lilinganisa ukuba kukangaphi umthombo wevidiyo unokondla isakhelo esipheleleyo sedatha entsha kumboniso.
Ireyithi yesakhelo sevidiyo idla ngokuba ngama-24, ama-25 okanye ama-30 eefreyimu ngesekhondi, kwaye okoko iphezulu kuneefreyimu ezingama-24 ngomzuzwana, ithathwa ngokuba igudile liliso lomntu. Ngenkqubela phambili yetekhnoloji yamva nje, abantu ngoku banokubukela ividiyo kwi-120 fps kwiindawo zemiboniso bhanyabhanya, kwiikhompyuter, nakwiselfowuni, ngoko abantu ngoku basebenzisa amaxabiso aphezulu efreyimu ukuthwebula ividiyo.
Amazinga asezantsi okuhlaziya isikrini akholisa ukwenza abasebenzisi ukuba badinwe kwaye bashiye umbono ombi womfanekiso wakho webrand.
Ke, lithetha ntoni ireyithi yokuhlaziya?
Ireyithi yokuhlaziya inokwahlulwa ngokwenqanaba lokuhlaziya elithe nkqo kunye nenqanaba lokuhlaziya elithe tye. Ireyithi yokuhlaziya isikrini ngokubanzi ibhekisa kwireyithi yokuhlaziya ngokuthe nkqo, oko kukuthi, inani lamaxesha umqa we-elektroniki uskena ngokuphindaphindiweyo umfanekiso kwiscreen se-LED.
Ngokwesiqhelo, linani lamaxesha apho isikrini se-LED siphinda sidwebe umfanekiso ngomzuzwana. Izinga lokuhlaziya isikrini lilinganiswa kwiHertz, idla ngokufinyezwa njenge "Hz". Umzekelo, ireyithi yokuhlaziya isikrini ye-1920Hz ithetha ukuba umfanekiso uhlaziywa amaxesha angama-1920 ngomzuzwana omnye.
Umahluko phakathi kwereyithi ephezulu yokuhlaziya kunye nenqanaba lokuhlaziya eliphantsi
Amaxesha amaninzi isikrini sihlaziywa, kokukhona imifanekiso igudileyo ngokwemigaqo yonikezelo olushukumayo kunye nokunciphisa i-flicker.
Into oyibonayo kudonga lwevidiyo ye-LED ngokwenene yimifanekiso emininzi eyahlukeneyo xa uphumle, kwaye intshukumo oyibonayo kungenxa yokuba isiboniso se-LED sihlala sihlaziywa, sikunika inkohliso yentshukumo yendalo.
Ngenxa yokuba iliso lomntu linesiphumo sokuhlala esibonakalayo, umfanekiso olandelayo ulandela owangaphambili ngokukhawuleza ngaphambi kokuba impembelelo ebuchotsheni iphele, kwaye ngenxa yokuba le mifanekiso yahluke kancinane, imifanekiso engashukumiyo iqhagamshela ukwenza intshukumo egudileyo, yendalo nje kuphela. isikrini sihlaziya ngokukhawuleza ngokwaneleyo.
Izinga eliphezulu lokuhlaziya isikrini sisiqinisekiso semifanekiso ekumgangatho ophezulu kunye nokudlala ividiyo egudileyo, kukunceda ukuba unxibelelane ngcono nophawu lwakho kunye nemiyalezo yemveliso kubasebenzisi ojolise kubo kwaye ubachukumise.
Ngakolunye uhlangothi, ukuba izinga lokuhlaziya umboniso liphantsi, ukuhanjiswa komfanekiso wesiboniso se-LED kuya kuba yinto engeyondalo. Kuza kubakho “imigca yokuskena emnyama” edanyazayo, imifanekiso ekrazukileyo nelandelayo, kunye “nemifanekiso eqingqiweyo” okanye “isiporho” eboniswe ngemibala eyahlukeneyo. Impembelelo yayo ukongeza kwividiyo, ukufota, kodwa nangenxa yokuba amashumi amawaka eebhalbhu ezikhanyayo ezidanyazayo imifanekiso ngaxeshanye, iliso lomntu linokuvelisa ukungonwabi xa lijongwa, kwaye lide libangele umonakalo wamehlo.
Amazinga asezantsi okuhlaziya isikrini akholisa ukwenza abasebenzisi ukuba badinwe kwaye bashiye umbono ombi womfanekiso wakho webrand.
Ngaba ireyithi yokuhlaziya ePhezulu ingcono kwizikrini ze-LED?
Izinga eliphezulu lohlaziyo lwesikrini likuxelela ukukwazi kwehardware yesikrini ukuvelisa kwakhona umxholo wesikrini amaxesha amaninzi ngesekondi. Ivumela ukunyakaza kwemifanekiso ukuba kube lula kwaye kucoceke kwividiyo, ngakumbi kwimiboniso emnyama xa ibonisa iintshukumo ezikhawulezayo. Ngaphandle koko, isikrini esinezinga eliphezulu lokuhlaziya siya kufaneleka ngakumbi kumxholo onenani elibalulekileyo lezakhelo ngesekhondi.
Ngokwesiqhelo, izinga lokuhlaziya le-1920Hz lilungile ngokwaneleyo kuninziIziboniso ze-LED. Kwaye ukuba umboniso we-LED kufuneka ubonise ividiyo yesenzo sesantya esiphezulu, okanye ukuba umboniso we-LED uya kufakwa kwikhamera, umboniso we-LED kufuneka ube nesantya sokuhlaziya ngaphezu kwe-2550Hz.
I-frequency yokuhlaziya ithathwa kukhetho olwahlukileyo lweetshiphusi zomqhubi. Xa usebenzisa i-chip yomqhubi oqhelekileyo, ireyithi yokuhlaziya umbala opheleleyo yi-960Hz, kwaye ireyithi yokuhlaziya yombala omnye kunye nombini yi-480Hz. xa usebenzisa i-chip yomqhubi we-latching kabini, izinga lokuhlaziya lingaphezulu kwe-1920Hz. Xa usebenzisa i-HD yenqanaba eliphezulu le-chip yomqhubi we-PWM, izinga lokuhlaziya lifikelela kwi-3840Hz okanye ngaphezulu.
I-HD yomgangatho ophezulu we-chip yomqhubi we-PWM, ≥ 3840Hz iholele izinga lokuhlaziya, umboniso wesikrini uzinzile kwaye ugudileyo, akukho ripple, akukho lag, akukho mvakalelo yembonakalo ebonakalayo, kungekhona nje ukunandipha umgangatho okhokelwayo, kunye nokukhusela okusebenzayo kombono.
Ekusetyenzisweni kobuchwephesha, kubalulekile ukubonelela ngezinga eliphezulu kakhulu lokuhlaziya. Oku kubaluleke ngakumbi kwimiboniso elungiselelwe ukuzonwabisa, imithombo yeendaba, imisitho yezemidlalo, ukufota okubonakalayo, njl.njl. ekufuneka ibanjwe kwaye ngokuqinisekileyo iya kurekhodwa kwividiyo ziikhamera zobuchwephesha. Izinga lokuhlaziya elidityaniswa kunye nekhamera yokurekhoda i-frequency iya kwenza umfanekiso ubonakale uphelele kwaye uthintele ukuqhwanyaza. Iikhamera zethu zirekhoda ividiyo ngokuqhelekileyo kwi-24, i-25,30 okanye i-60fps kwaye kufuneka siyigcine ivumelanisa kunye nezinga lokuhlaziya isikrini njengento eninzi. Ukuba singqamanisa umzuzu wokurekhoda kwekhamera kunye nomzuzu wokutshintsha umfanekiso, sinokunqanda umgca omnyama wokutshintsha kwesikrini.
Umahluko kwireyithi yokuHlaziya phakathi kwe-3840Hz kunye ne-1920Hz izikrini ze-LED.
Ngokubanzi, izinga lokuhlaziya le-1920Hz, iliso lomntu bekunzima ukuva ukuqhwanyaza, kuba intengiso, ukubukela ividiyo kwanele.
Izinga lokuhlaziya i-LED elingekho ngaphantsi kwe-3840Hz, ikhamera yokubamba uzinzo lwesikrini somfanekiso, inokusombulula ngokufanelekileyo umfanekiso wenkqubo yentshukumo ekhawulezayo yokulandela kunye nokufiphaza, ukuphucula ukucaca kunye nokuchasana komfanekiso, ukuze isikrini sevidiyo sithambile kwaye Ukujonga okugudileyo, ixesha elide akulula ukudinwa; ngetekhnoloji yokulungiswa kwe-anti-gamma kunye ne-point-by-point yokulungiswa kokukhanya kobuchwephesha, ukuze umfanekiso oguquguqukayo ubonise ungokoqobo kunye nendalo, iyunifomu kwaye ihambelana.
Ke ngoko, ngophuhliso oluqhubekayo, ndiyakholelwa ukuba umgangatho wokuhlaziya wesikrini esikhokelelweyo uya kutshintshela kwi-3840Hz okanye ngaphezulu, kwaye emva koko ube ngumgangatho woshishino kunye neenkcukacha.
Ewe, ireyithi yokuhlaziya i-3840Hz iya kuxabisa ngakumbi ngokweendleko, sinokwenza ukhetho olufanelekileyo ngokwemeko yokusetyenziswa kunye nohlahlo lwabiwo-mali.
Ukuqukumbela
Nokuba ufuna ukusebenzisa isikrini se-LED sangaphakathi okanye sangaphandle sokwenza uphawu, umboniso wevidiyo, usasazo, okanye umboniso bhanyabhanya, kufuneka usoloko ukhetha isikrini se-LED esibonelela ngesantya esiphezulu sokuhlaziya isikrini kwaye singqamanise nesantya sesakhelo esirekhodwe yikhamera yakho ukuba ufuna ukufumana imifanekiso esemgangathweni ophezulu kwisikrini, kuba ngoko umzobo uya kubonakala ucacile kwaye uphelele.
