  • I-HDR ithuthukisa ukujula kombala, ukukhanya nokugqama ukuze uthole ukuzizwisa okucebile kokubuka.
  • I-DCR ilungisa ngokuzenzakalelayo ukukhanya nokugqama ngokusekelwe kokuqukethwe okuboniswa esikrinini.
  • I-HDR ilungele okuqukethwe kwekhwalithi njengamamuvi nemidlalo, kuyilapho i-DCR isebenziseka kalula.
  • Ukukhetha phakathi kobubili ubuchwepheshe kuncike ezidingweni zakho ezithile kanye nokusetshenziswa okuyinhloko kocingo.

Emhlabeni wabaqaphi namathelevishini, ubuchwepheshe buguquka njalo ukuthuthukisa umuzwa wethu wokubuka. Amagama amabili okungenzeka uhlangane nawo ngenkathi usesha isibonisi yilawa I-HDR (i-High Dynamic Range) y I-DCR (Dynamic Contrast Ratio). Bobabili ubuchwepheshe buhlose ukuthuthukisa ikhwalithi yesithombe, kodwa bakwenza ngezindlela ezahlukene. Asho ukuthini ngempela la ma-akhronimi futhi athinta kanjani umuzwa wakho wokubuka? Yilokhu esizokuhlola ngokujulile.

Qonda umehluko phakathi HDR y DCR Kubalulekile uma ucabanga ukuthenga imonitha entsha noma ithelevishini. Izikhathi eziningi, abakhiqizi bathuthukisa lezi zici ngaphandle kokuchaza ukuthi empeleni benzani. Lapha sikutshela konke odinga ukukwazi ukuze wenze isinqumo esinolwazi futhi ukhethe idivayisi evumelana kangcono nezidingo zakho.

Iyini i-HDR?

HDRkusho ukuthini Ibanga Eliphezulu Lamandla NgesiNgisi, ubuchwepheshe obufuna ukwandisa ububanzi bemibala nokugqama esithombeni. Lokhu kuhumusha ku imibala ukhombise impilo futhi ungokoqobo, imininingwane engcono ezindaweni ezikhanyayo nezimnyama, kanye nokuzizwisa okugxile kakhulu kokubuka. Amamonitha e-HDR ngokuvamile anombala wokujula kwamabhithi angu-10 noma ngaphezulu, okuwavumela ukuba abonise ububanzi obubanzi bemibala nokukhanya uma kuqhathaniswa nezibonisi ezijwayelekile.

Izinzuzo ze-HDR

  • Imibala eminingi ecacile neningiliziwe: Ubuchwepheshe be-HDR benza imibala ibukeke iseduze nengokoqobo, ilungele amamuvi, imidlalo nokuqukethwe okuyingcaca.
  • Ukugqama okukhulu: I-HDR ikuvumela ukuthi ubonise okumnyama okujulile nokumhlophe okugqamile, ithuthukisa umehluko ekukhanyeni nasethunzini.
  • Imininingwane ethuthukisiwe: Kuzo zombili izindawo ezimnyama nezikhanyayo, i-HDR yembula imininingwane eyengeziwe, enikeza umuzwa wokubuka ogxilile.

Iyini i-DCR?

DCR, noma I-Dynamic Contrast Ratio, ubuchwepheshe obuzilungisa ngokuzenzakalelayo ukukhanya nokugqama kwesikrini ngokusekelwe kokuqukethwe okuboniswayo. Inhloso yaso ukuthuthukisa ikhwalithi yesithombe ngokwandisa umehluko phakathi kwamathoni alula kakhulu namnyama kakhulu. Abaqaphi abane-DCR bahlaziya okuqukethwe ngesikhathi sangempela futhi basebenzise izilungiselelo zokukhanya eziguquguqukayo ukuze bathuthukise ukugqama okubonakalayo.

Izinzuzo ze-DCR

  • Ukulungiswa kokukhanya okuzenzakalelayo: I-DCR ivumelanisa isithombe ngokuzenzakalelayo, ikusindise ekubeni ulungise amazinga okukhanya mathupha.
  • Imininingwane ethuthukisiwe ezindaweni zokugqama okuphezulu: Ilungele izigcawu ezinomehluko omkhulu ekugqameni, njengamamuvi namavidiyo.
  • Ukusebenza: Iwusizo ekusetshenzisweni okuvamile njengoba iphendula ngempumelelo ekuhlukeni kokuqukethwe.

Umehluko omkhulu phakathi kwe-HDR ne-DCR

Nakuba kakhulu HDR njengoba DCR Bafuna ukuthuthukisa ikhwalithi yesithombe, bakwenza ngezindlela ezahlukene nangamazinga ahlukene okusebenza. Okulandelayo, sihlaziya umehluko wabo omkhulu:

  • Ukujula kombala: I-HDR igxile ekuletheni imibala eyiqiniso ngokujula kwamabhithi ayi-10 noma ngaphezulu, kuyilapho i-DCR isithinti i-gamut yombala.
  • Ukukhanya: I-HDR isebenzisa ibanga elibanzi lokukhanya ukuze ibonise imininingwane kuzo zombili izindawo ezikhanyayo nezimnyama. I-DCR ilungisa ukukhanya ngokushintshashintshayo, kodwa ayifinyeleli ububanzi obubanzi be-HDR.
  • Aplicación: I-HDR ilungele okuqukethwe kwekhwalithi ephezulu njengamamuvi nemidlalo. I-DCR ifaneleka kakhulu ukusetshenziswa okujwayelekile kanye nezimo lapho ukusebenza kuyisihluthulelo.

Yibuphi ubuchwepheshe okufanele ukhethe?

Ukukhetha kwakho kuzoncika ezidingweni zakho ezithile. Uma ufuna okubukwayo okucebile ngemininingwane, imibala nokugqama kwemidlalo, amamuvi noma umsebenzi wezithombe, HDR Kuyoba inketho engcono kakhulu. Ngakolunye uhlangothi, uma udinga imonitha elizivumelanisa ngokuzenzakalelayo nokuqukethwe okuhlukile ngaphandle kokulungiswa okuningi, DCR kungase kube usizo ngokwengeziwe.

Ukwengeza, kubalulekile ukusho ukuthi i-HDR idinga okuqukethwe okuthile ukusizakala ngezinzuzo zayo, kuyilapho DCR isebenza nganoma yiluphi uhlobo lokuqukethwe okubonisiwe. Nakuba bobabili ubuchwepheshe bunezinzuzo, ukukhetha okukodwa noma okunye kuzoncika ekusetshenzisweni okuyinhloko ozokunikeza idivayisi yakho.

Izibonelo zobuchwepheshe obuhlobene

Emkhakheni we HDR, kunamazinga amaningana, ngalinye linezici ezithile:

  • I-HDR10: Yizinga elivame kakhulu nelisekelwa kabanzi. Inikeza amabhithi ayi-10 okujula kombala nokukhanya okuphezulu okungafika ku-1.000 nits.
  • I-HDR10 +: Ifana ne-HDR10, kodwa enemethadatha eguquguqukayo yokulungiswa okunembe kakhudlwana kokukhanya nokugqama.
  • Umbono weDolby: Ifomethi ye-premium esebenzisa umbala we-12-bit futhi esekela ukukhanya okuphezulu okungafika ku-10.000 nits.

Ngakolunye uhlangothi, ubuchwepheshe DCR Ayinawo amazinga ahlukene, kodwa isetshenziswa ezinhlobonhlobo zama-monitor namathelevishini avela kumikhiqizo ehlukene.

Bobabili ubuchwepheshe bunikeza izinzuzo eziyingqayizivele mayelana nekhwalithi yesithombe. Nakuba i-HDR igqama ngemininingwane nokunotha kombala, i-DCR ihlinzeka ngesixazululo esisebenzayo sokulungiswa kokugqama okuzenzakalelayo. Ukwenza isinqumo esifanele kuhilela ukuhlola izinto eziza kuqala kuwe: ingabe ufuna okuhlangenwe nakho okubukwayo okungcono kakhulu noma ukhetha ukusebenza okuguquguqukayo ukuze usetshenziswe nsuku zonke?
