Gawo 1: HDR ndi SDR ndi chiyani?
Zithunzi za SDR, kapena Standard Dynamic Range, ndiye muyeso wapano wamakanema ndi makanema.SDR imafotokoza zithunzi kapena makanema pogwiritsa ntchito siginecha yanthawi zonse ya gamma.Mapiritsi a gamma ochiritsira adachokera ku malire a chubu cha cathode ray (CRT) chomwe chimalola kuwala kwakukulu kwa 100 cd / m2.
HDR, kuyimira High Dynamic Range, ndi njira yojambula yomwe imajambula, kukonza, ndi kutulutsanso zomwe zili m'njira yoti tsatanetsatane wamithunzi ndi zowoneka bwino za chochitika zimawonjezeka.Ngakhale HDR idagwiritsidwa ntchito pojambula zachikhalidwe m'mbuyomu, posachedwa idalumphira ku mafoni, ma TV, oyang'anira, ndi zina zambiri.
Gawo 2: HDR vs. SDR Poyerekeza: Kusiyana Pakati pa HDR ndi SDR
SDR ili ndi malire chifukwa cha kuthekera kwake kungoyimira kachigawo kakang'ono kazomwe HDR imatha.HDR imasunga tsatanetsatane pazithunzi zomwe kusiyanitsa kwa chowunikira kungakhale cholepheretsa.SDR, kumbali ina, ilibe luso limeneli.Kusiyana kwakukulu kuli pamitundu yosiyanasiyana ya gamut ndi kuwala.Mukudziwa, SDR imalola mtundu wa sRGB komanso kuwala kuchokera ku 0 mpaka 100nits.Pomwe HDR ili ndi mtundu wokulirapo mpaka ku DCI - P3, malire owoneka bwino akumtunda komanso malire ochepera akuda.Panthawi imodzimodziyo, imapangitsa kuti chifaniziro chonse chikhale bwino molingana ndi kusiyana, kusintha kwa grayscale ndi miyeso ina, kubweretsa chidziwitso chozama kwa wodziwa.
Kunena mwachidule, poyerekezera HDR ndi SDR, HDR imakulolani kuti muwone zambiri zatsatanetsatane ndi mtundu wazithunzi zomwe zili ndi mawonekedwe apamwamba kwambiri.Izi zikutanthauza kuti HDR ndiyowala kuposa SDR.HDR imakulolani kuti muwone zambiri ndi mitundu pazithunzi.HDR ndiyopambana pazinthu izi:
◉ Kuwala:HDR imalola kuwala kumtunda mpaka 1000 nits ndikutsika mpaka pansi pa 1 nit.
◉ Mtundu wamtundu:HDR nthawi zambiri imatenga P3, ndipo ngakhale Rec.2020 color gamut.SDR imagwiritsa ntchito Rec.709 yonse.
◉ Kuzama kwamtundu:HDR ikhoza kukhala yakuzama kwa mtundu wa 8-bit, 10-bit ndi 12-bit.Ngakhale SDR nthawi zambiri imakhala mu 8-bit, ndipo ochepa amagwiritsa ntchito 10-bit.
Gawo 3: Miyezo iwiri Yaikulu ya HDR: Dolby Vision, HDR10 ndi HDR10 +
Kwenikweni, palibe tanthauzo lomaliza la miyezo ya HDR.Pali miyezo iwiri yodziwika bwino yomwe imagwiritsidwa ntchito masiku ano, Dolby Vision ndi HDR10.Kuphatikiza apo, pali mtundu watsopano wa HDR10+, womwe cholinga chake ndi kuyambitsa HDR yamphamvu pamtundu wa HDR10 pomwe ikukhalabe yachifumu.Tilowa mu kusiyana pakati pa mitundu iwiri yayikulu ya HDR pansipa.
Dolby Vision
Dolby Vision ndi mulingo wa HDR womwe umafuna kuti oyang'anira apangidwe makamaka ndi chipangizo cha Dolby Vision hardware.Pali chindapusa cha Dolby Vision, pafupifupi $3 pa TV iliyonse.Monga HDR10, Dolby Vision imagwiritsa ntchito Rec.2020 wide color gamut, 1000 nits of lightness, koma imatenga kuya kwa mtundu wa 12-bit ndikuthandizira mawonekedwe a data.
HDR10
HDR10 ndi muyezo wotseguka, ndipo simuyenera kulipira chilichonse kuti mugwiritse ntchito.Nambala "10" imayimira kuya kwa mtundu wa 10bit.Kuphatikiza pa izi, HDR10 imalimbikitsanso kugwiritsa ntchito gamut Rec.2020, 1000 nits of lightness, ndi static data processing mode.
HDR10 ndiye mulingo wodziwika bwino wa HDR womwe pafupifupi onse opanga ma TV ndi opereka ma TV, monga Sony, Disney, 20th Century Fox, Warner Bros., Paramount, Universal, ndi Netflix amatenga HDR10 kuti apange ma disks a 4K UHD Blu ray.Kupatula apo, zida ngati Xbox Mmodzi, PS4, Apple TV imathandiziranso HDR10.
HDR10 vs Dolby Vision - Pali Kusiyana Kotani?
HDR10 ndi Dolby Vision ndi mitundu iwiri yayikulu ya HDR.Kusiyana kwake ndikuti HDR10 ndi yotseguka komanso yosakhala eni ake, pomwe Dolby Vision imafuna chilolezo ndi chindapusa kuchokera ku Dolby.
Ndipo ngakhale Dolby Vision pakadali pano imatha kupanga chithunzi chabwinoko, palibe ma TV omwe angatengere mwayi pazomwe amapereka kusiyana ndi HDR10.
Komabe, Dolby Vision imapereka chithunzi chabwinoko, makamaka chifukwa cha metadata yake yosinthika.
HDR10+
Monga tafotokozera pamwambapa, pali mtundu wina wa HDR10+.HDR10+ ndi mulingo wa HDR wokhazikitsidwa ndi Samsung wa Dolby Vision, womwe ndi wofanana ndi Vision yachisinthiko ya HDR10.Zofanana ndi Dolby Vision, HDR10+ imathandizira mawonekedwe amtundu wa data, koma HDR10+ ndi mulingo wotseguka, womwe umafuna kupeza zowonera bwino pamtengo wotsika.
Pakadali pano, HDR10 ndiyosavuta komanso yofala kwambiri, pomwe Dolby Vision ndiye njira yabwino kwambiri.Pa nthawi yolemba izi, DR10 + zomwe zili mkati zimangopezeka pazinthu zochepa zotsatsira (kuphatikizapo Amazon) ndi ma disks, koma ma TV ochulukirapo akuyamba kuthandizira HDR10 +.
Gawo 4: Kodi Kukhazikitsa Kwanu Kutha Kusewera HDR?
Mukazindikira zomwe zili mu HDR, kaya ndi kanema wa HDR kapena masewera a HDR, muyenera kuwonetsetsa kuti kukhazikitsa kwanu kumatha kuwonetsa zomwe zili mu HDR.
