- 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.
Ezweni lama-monitor namathelevishini, ubuchwepheshe buhlala bushintsha ukuze kuthuthukiswe ulwazi lwethu lokubuka. Amagama amabili okungenzeka ukuthi uke wawabona ngenkathi usesha isikrini yi -HDR (High Dynamic Range) kanye ne-DCR (Dynamic Contrast Ratio) . Zombili lezi zobuchwepheshe zihlose ukuthuthukisa ikhwalithi yesithombe, kodwa zikwenza ngezindlela ezahlukene. Zisho ukuthini ngempela lezi zifinyezo, futhi zithinta kanjani ulwazi lwakho lokubuka? Yilokho esizokuhlola ngokujulile.
Ukuqonda umehluko phakathi kwe-HDR ne -DCR kubalulekile uma ucabanga ukuthenga i-monitor entsha noma i-TV. Ngokuvamile, abakhiqizi bakhangisa lezi zici ngaphandle kokuchaza ukuthi zenzani ngempela. Nakhu konke okudingeka ukwazi ukuze wenze isinqumo esinolwazi futhi ukhethe idivayisi efanelana kahle nezidingo zakho.
Iyini i-HDR?
I-HDR , emele i- High Dynamic Range , ubuchwepheshe obuhlose ukwandisa ububanzi bombala kanye nokuqhathanisa esithombeni. Lokhu kuphumela emibala egqamile nengokoqobo , imininingwane engcono ezindaweni ezikhanyayo nezimnyama, kanye nesipiliyoni sokubuka esijulile. Ama-HDR monitor ngokuvamile anokujula kombala okungama-bits ayi-10 noma ngaphezulu, okubavumela ukuthi babonise ububanzi obukhulu 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?
I-DCR , noma i-Dynamic Contrast Ratio , ubuchwepheshe obulungisa ngokuzenzakalelayo ukukhanya kwesikrini kanye nokuqhathanisa ngokusekelwe kokuqukethwe okubonisiwe. Umgomo wayo ukwenza ngcono ikhwalithi yesithombe ngokwandisa umehluko phakathi kwamathoni alula kakhulu namnyama kakhulu. Ama-monitha ane-DCR ahlaziya okuqukethwe ngesikhathi sangempela futhi asebenzise izilungiselelo zokukhanya eziguquguqukayo ukuze athuthukise ukuqhathanisa 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 kokubili i-HDR ne -DCR zihlose ukuthuthukisa ikhwalithi yesithombe, zenza kanjalo ngezindlela ezahlukene nangamazinga ahlukene okusebenza kahle. Ngezansi, sihlaziya umehluko wazo oyinhloko:
- 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 ulwazi olubonakalayo olunemininingwane eminingi, umbala, kanye nomehluko wemidlalo, ama-movie, noma umsebenzi wokuklama imidwebo, i-HDR izoba inketho engcono kakhulu. Ngakolunye uhlangothi, uma udinga i-monitor evumelana ngokuzenzakalelayo nokuqukethwe okuhlukile ngaphandle kokulungiswa okuningi, i-DCR ingase ibe usizo kakhulu.
Ngaphezu kwalokho, kubalulekile ukusho ukuthi i-HDR idinga okuqukethwe okuthile ukuze isebenzise izinzuzo zayo, kuyilapho i-DCR isebenza nanoma yiluphi uhlobo lokuqukethwe. Nakuba zombili lezi zobuchwepheshe zinezinzuzo, ukukhetha okukodwa noma okunye kuzoncika endleleni oyisebenzisa ngayo idivayisi yakho ngokuyinhloko.
Izibonelo zobuchwepheshe obuhlobene
Emkhakheni we -HDR , kunezindinganiso eziningana, ngayinye inezici 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 be-DCR abunazo izindinganiso ezahlukene, kodwa busetshenziswa kuma-monitor namathelevishini ahlukahlukene 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?
Umbhali oshisekayo ngomhlaba wamabhayithi nobuchwepheshe ngokujwayelekile. Ngiyathanda ukwabelana ngolwazi lwami ngokubhala, futhi yilokho engizokwenza kule bhulogi, ngikubonise zonke izinto ezithakazelisayo kakhulu ngamagajethi, isofthiwe, ihadiwe, izitayela zobuchwepheshe, nokuningi. Inhloso yami ukukusiza ukuthi uzulazule emhlabeni wedijithali ngendlela elula nejabulisayo.
