Kodi ndi kangati komwe mwayesa kujambula kanema yomwe ikuseweredwa pa skrini yanu ya LED ndi foni kapena kamera yanu, kuti mupeze mizere yokhumudwitsayo yomwe imakulepheretsani kujambula kanemayo moyenera?
Posachedwapa, nthawi zambiri timakhala ndi makasitomala amatifunsa za kutsitsimuka kwa skrini yotsogozedwa, ambiri mwa iwo ndi zosowa zojambula, monga XR pafupifupi kujambula zithunzi, etc. Ndikufuna kutenga mwayi uwu kuti tikambirane nkhaniyi Kuti tiyankhe funso la chiyani ndi kusiyana pakati pa kutsitsimula kwakukulu ndi kutsitsimula kochepa.
Kusiyana Pakati pa Refresh Rate ndi Frame Rate
Mitengo yotsitsimutsa nthawi zambiri imakhala yosokoneza, ndipo imatha kusokonezedwa mosavuta ndi mitengo yazithunzi zamakanema (FPS kapena mafelemu pamphindikati ya kanema)
Mtengo wotsitsimutsa ndi mawonekedwe azithunzi ndizofanana kwambiri. Onse awiri amaimira manambala a nthawi yomwe chithunzi chokhazikika chimawonetsedwa pamphindikati. Koma kusiyana kwake ndikuti mtengo wotsitsimutsa umayimira chizindikiro cha kanema kapena chiwonetsero pomwe mtengo wa chimango umayimira zomwe zili.
Mlingo wotsitsimutsa wa chophimba cha LED ndi kuchuluka kwa nthawi pamphindi imodzi pomwe zida zamtundu wa LED zimakoka deta. Izi ndizosiyana ndi muyeso wa chimango chomwe chiwonjezero chaZojambula za LEDzikuphatikizapo kujambula mobwerezabwereza mafelemu ofanana, pamene furemu mlingo amayesa kangati gwero la kanema akhoza kudyetsa furemu lonse la deta latsopano chiwonetsero.
Mafelemu a kanema nthawi zambiri amakhala 24, 25 kapena 30 mafelemu pamphindikati, ndipo malinga ngati ali apamwamba kuposa mafelemu 24 pamphindikati, nthawi zambiri amaonedwa kuti ndi osalala ndi diso la munthu. Ndi kupita patsogolo kwaukadaulo kwaposachedwa, anthu tsopano amatha kuwonera makanema pa 120 fps m'malo owonetsera makanema, pamakompyuta, ngakhale pamafoni am'manja, kotero anthu akugwiritsa ntchito mitengo yokwera kwambiri pojambulira makanema.
Miyezo yocheperako yotsitsimutsa zenera imapangitsa ogwiritsa ntchito kutopa ndikusiya chithunzi choyipa cha mtundu wanu.
Ndiye, Kodi Refresh Rate Imatanthauza Chiyani?
Mlingo wotsitsimutsa ukhoza kugawidwa mulingo wotsitsimutsa woyima komanso mulingo wotsitsimutsa wopingasa. Mlingo wotsitsimutsa zenera nthawi zambiri umatanthawuza kuchuluka kwa mawonekedwe otsitsimutsa, ndiko kuti, kuchuluka kwa nthawi yomwe mtengo wamagetsi umasanthula mobwerezabwereza chithunzicho pa skrini ya LED.
M'mawu wamba, ndi kuchuluka kwa nthawi zomwe chiwonetsero cha LED chimajambulanso chithunzi pamphindikati. Mlingo wotsitsimutsa pazenera umayesedwa mu Hertz, nthawi zambiri amafupikitsidwa ngati "Hz". Mwachitsanzo, kutsitsimula kwa skrini kwa 1920Hz kumatanthauza kuti chithunzicho chimatsitsimutsidwa ka 1920 mu sekondi imodzi.
Kusiyana Pakati pa Mtengo Wotsitsimula Kwambiri Ndi Mtengo Wotsitsimula Wochepa
Nthawi zambiri chinsalu chimatsitsimutsidwa, m'pamenenso zithunzizo zimakhala zosalala bwino potengera kusuntha komanso kucheperako.
Zomwe mukuwona pakhoma la kanema wa LED kwenikweni ndi zithunzi zingapo zosiyana pakupuma, ndipo mayendedwe omwe mukuwona ndi chifukwa chiwonetsero cha LED chimatsitsimutsidwa nthawi zonse, ndikukupatsani chinyengo chakuyenda kwachilengedwe.
Chifukwa diso la munthu limakhala ndi mawonekedwe okhalamo, chithunzi chotsatira chimatsatira cham'mbuyomo nthawi yomweyo chithunzicho muubongo chisanazimiririke, ndipo chifukwa zithunzizi zimangosiyana pang'ono, zithunzi zosasunthika zimalumikizana ndikupanga kusuntha kosalala, kwachilengedwe bola chophimba chimatsitsimula msanga mokwanira.
Mlingo wapamwamba wotsitsimutsa zenera ndi chitsimikizo cha zithunzi zapamwamba komanso kusewerera mavidiyo mosalala, kukuthandizani kuti muzitha kufotokozera bwino zamtundu wanu ndi mauthenga azinthu kwa omwe mukufuna ndikuwasangalatsa.
Mosiyana ndi izi, ngati chiwonetsero chotsitsimutsa chili chochepa, kutumizira kwazithunzi za chiwonetsero cha LED kudzakhala kwachilendo. Padzakhalanso "mizere yojambula yakuda", zithunzi zong'ambika ndi zotsatizana, ndi "zojambula" kapena "ghosting" zowonetsedwa mumitundu yosiyanasiyana. Zotsatira zake kuwonjezera pa kanema, kujambula, komanso chifukwa zikwizikwi za mababu akuthwanima zithunzi nthawi imodzi, diso la munthu likhoza kutulutsa chisokonezo poyang'ana, ndipo ngakhale kuwononga maso.
Miyezo yocheperako yotsitsimutsa zenera imapangitsa ogwiritsa ntchito kutopa ndikusiya chithunzi choyipa cha mtundu wanu.
Kodi Mtengo Wotsitsimula Wapamwamba Ndi Bwino Pazowonetsera za LED?
Mlingo wotsitsimula wotsogola wapamwamba umakuwuzani kuthekera kwa Hardware ya skrini kuti ipangitsenso zomwe zili pazenera kangapo pamphindikati. Imalola kusuntha kwa zithunzi kukhala kosavuta komanso koyera mu kanema, makamaka pazithunzi zakuda powonetsa kusuntha mwachangu. Kupatula apo, chinsalu chokhala ndi chiwongolero chapamwamba chotsitsimutsa chidzakhala choyenera kwambiri pazomwe zili ndi mafelemu ochulukirapo pamphindikati.
Nthawi zambiri, kutsitsimula kwa 1920Hz ndikwabwino kokwanira kwa ambiriMawonekedwe a LED. Ndipo ngati chiwonetsero cha LED chikuyenera kuwonetsa kanema wothamanga kwambiri, kapena ngati chiwonetsero cha LED chidzajambulidwa ndi kamera, chiwonetsero cha LED chiyenera kukhala ndi kutsitsimula kopitilira 2550Hz.
Ma frequency otsitsimula amachokera ku zosankha zosiyanasiyana za ma driver chips. Mukamagwiritsa ntchito chip wamba woyendetsa, mulingo wotsitsimutsa wamitundu yonse ndi 960Hz, ndipo mulingo wotsitsimutsa wamtundu umodzi ndi wapawiri ndi 480Hz. Mukamagwiritsa ntchito chip chapawiri latching driver, mulingo wotsitsimutsa uli pamwamba pa 1920Hz. Mukamagwiritsa ntchito chipangizo chapamwamba cha HD PWM driver chip, mulingo wotsitsimutsa umakhala mpaka 3840Hz kapena kupitilira apo.
Chip chapamwamba cha HD PWM driver chip, ≥ 3840Hz led refresh rate, chiwonetsero chazenera chokhazikika komanso chosalala, chosasunthika, chopanda kuchedwa, chosawoneka bwino, sichingasangalale ndi mawonekedwe otsogola, komanso kuteteza masomphenya.
Pakugwiritsa ntchito akatswiri, ndikofunikira kupereka chiwongola dzanja chokwera kwambiri. Izi ndizofunikira makamaka pazosangalatsa, zoulutsira mawu, zochitika zamasewera, kujambula zithunzi, ndi zina zambiri zomwe ziyenera kujambulidwa ndipo zidzajambulidwa pavidiyo ndi makamera akatswiri. Mlingo wotsitsimutsa womwe umalumikizidwa ndi pafupipafupi kujambula kwa kamera umapangitsa chithunzicho kukhala changwiro ndikuletsa kuphethira. Makamera athu amajambula kanema nthawi zambiri pa 24, 25,30 kapena 60fps ndipo tifunika kuyisunga kuti igwirizane ndi mawonekedwe otsitsimula ngati kuchulukitsa. Ngati tigwirizanitsa mphindi yojambulira kamera ndi mphindi yakusintha kwazithunzi, titha kupewa mzere wakuda wakusintha pazenera.
Kusiyana Kwa Mtengo Wotsitsimutsa Pakati pa 3840Hz Ndi 1920Hz Zowonera za LED.
Nthawi zambiri, kuchuluka kwa mpumulo wa 1920Hz, diso lamunthu lakhala lovuta kumva kuthwanima, chifukwa kutsatsa, kuwonera makanema kwakhala kokwanira.
Kuwonetsa kukhazikika kwa zosakwana 3840hz, kamera kuti igwire chithunzithunzi cha njirayi, imatha kuthana ndi chithunzicho mwachangu kosalala, kuwonera nthawi yayitali sikophweka kutopa; ndi ukadaulo wotsutsa-gamma wowongolera komanso ukadaulo wowongolera kuwala kwa point-by-point, kotero kuti chithunzi champhamvu chiwonetsere zenizeni komanso zachilengedwe, zofananira komanso zosagwirizana.
Chifukwa chake, ndikukula kosalekeza, ndikukhulupirira kuti mulingo wotsitsimutsa wa skrini yotsogozedwa usintha kukhala 3840Hz kapena kupitilira apo, ndiyeno kukhala mulingo wamakampani ndi mawonekedwe.
Zachidziwikire, mtengo wotsitsimutsa wa 3840Hz udzakhala wokwera mtengo kwambiri malinga ndi mtengo, titha kupanga chisankho choyenera malinga ndi momwe amagwiritsidwira ntchito komanso bajeti.
Mapeto
Kaya mukufuna kugwiritsa ntchito zotsatsa zamkati kapena zakunja zotsatsa za LED kuti mupange chizindikiro, makanema, kuwulutsa, kapena kujambula, nthawi zonse muyenera kusankha chophimba cha LED chomwe chimapereka chiwonetsero chapamwamba chotsitsimutsa ndikugwirizanitsa ndi chimango chojambulidwa ndi kamera yanu ngati mukufuna kupeza zithunzi zapamwamba kuchokera pazenera, chifukwa ndiye chojambula chidzawoneka bwino komanso changwiro.
