Kodi HDR pa TV ndi chiyani, mitundu yomwe imathandizira komanso momwe mungathandizire ukadaulo

HDR (High Dynamic Range) pa TV ndi chinthu chosankha chomwe chimatanthawuza mtundu wabwino kwambiri wazithunzi mukawonera makanema. Ukadaulo wa HDR womwe umagwiritsidwa ntchito pa TV masiku ano umasintha mtundu wa chithunzi chomwe mumachiwona. Mitundu yowonekera pazenera imakhala yomveka bwino, ndipo chithunzicho – chachilengedwe. Mawonekedwe a HDR pa TV amakupatsani mwayi wowonetsa zithunzi zokhala ndi tonal yayikulu, kuti mutha kusangalala ndi tsatanetsatane wazithunzi zakuda komanso zowala kwambiri.

Kodi HDR pa TV ndi chiyani, Ubwino wa High Dynamic Range

Mawonekedwe a HDR pa TV amapangitsa chithunzicho kukhala chenicheni, chomwe chimapatsa wowonerera zochitika zabwino pamene akuwonera mafilimu kapena mapulogalamu omwe amakonda. Mitundu yowoneka bwino imapangitsa kuwonera machesi ndi masewera ena kukhala kosangalatsa kwambiri. Dongosolo la HDR pa TV silifanana nthawi zonse. Mitundu yomwe ilipo pamsika imasiyana mumtundu wazithunzi (HDR 10, HDR 10+, HLG ndi Dolby Vision zilipo). Ubwino wa chithandizo cha HDr pa TV:

1. Kusankha kumeneku kumapereka mitundu yolemera komanso yosiyana kwambiri.
2. 4K TV yophatikizidwa ndi HDR imalola ogwiritsa ntchito kusangalala ndikuyenda kosalala komanso zithunzi zenizeni.

Ndikoyenera kudziwa kuti zithunzi zomwe zikuwonetsedwa pazenera zikuwonetsa zomwe maso amunthu amawona. Mithunzi yambiri yamtundu uliwonse ilipo, zomwe zimapangitsa chithunzicho kukhala chachibadwa.

Mawonekedwe a HD pa TV ndiwothandiza kwambiri pakuwonera zojambula zachilengedwe ndi makanema akujambulidwa ndi zida zapamwamba kwambiri zopangira. Mitundu imakhalabe yofanana, kotero imvi, zakuda ndi mitundu ina zimakhala zolimba, zowala komanso zomveka bwino. [id id mawu = “attach_2866” align = “aligncenter” wide = “512”]

Ndi ma TV ati omwe amathandizira HDR

Pali ma TV ambiri a HDR omwe amapezeka pamsika. Komabe, posankha, muyenera kuyang’ana pazigawo zofunika kwambiri kuti muthe kusangalala ndi chithunzithunzi chabwino kwambiri. HDR +
Samsung Smart TV ndiye kuphatikiza koyenera kwa zochitika zozama mukawonera makanema kapena kusewera masewera. Komanso pamsika pali mitundu yotsatirayi ya Smart TV yomwe imathandizira kuchuluka kwamphamvu:

1. Ma TV a Samsung adzakhala othandiza kwambiri kwa ogwiritsa ntchito omwe amakonda masewera ndi makanema ochititsa chidwi. Makhalidwe abwino kwambiri amayendera limodzi ndi mtengo wokwanira, ndipo zotsatira zake zimawonekera kwambiri chifukwa cha kuwala kwa FALD kosiyanasiyana.
2. Mitundu ya Toshiba ndi ma TV otsika mtengo omwe nthawi zambiri amathandizira HDR10 ndi Dolby Vision. Chifukwa cha mtengo wawo wotsika, simungayembekeze zotsatira zochititsa chidwi kuchokera kwa iwo, monga momwe zilili ndi zitsanzo zamtengo wapatali, koma kusiyana kwa khalidwe la HDR kumawonekera pang’onopang’ono.
3. Ma TV a Sony amagwirizana kwathunthu ndi PlayStation 5. Amagwiritsa ntchito kuwala kwamitundu yambiri. Mutha kusankha kuchokera kumitundu yokhala ndi Dolby Visi, HDR 10 ndi HDR 10+, chifukwa chomwe zotsatira zake pakuwonera zimakhutiritsa ngakhale ogwiritsa ntchito omwe akufuna kwambiri.
4. Panasonic imapereka ma TV a 65-inchi omwe amatsimikizira zamtundu wapamwamba kwambiri komanso ziyembekezo za HDR. Mitundu yowoneka bwino imayenera kuyang’aniridwa, kotero filimu iliyonse yomwe mumawonera imakupatsani mwayi wosaiwalika komanso chithunzi chabwino kwambiri.

Mawonekedwe a HDR omwe alipo

HDR (High Dynamic Range) imatanthawuza kuti “high Dynamic range”, yomwe, kumbali imodzi, imagwirizana ndi lingaliro laukadaulo, koma mbali inayo, imachepetsa kwambiri. Chofunika kwambiri pankhaniyi ndi mtundu wa tonal wa chithunzicho. HDR imakulolani kuti muwone mitundu yosiyanasiyana yazinthu zabwino zomwe zimafalikira pakati pa zopepuka komanso zakuda kwambiri. Zotsatira zake, mitundu imakhala yowoneka bwino, imatenga mawonekedwe achilengedwe, ndipo tsatanetsatane ndi wakuthwa. Izi zimawonekera makamaka m’mawonedwe omwe ali akuda mwa iwo okha koma okhala ndi mawanga owala. Popeza pali miyezo ingapo yaukadaulo ya HDR pamsika, ndikofunikira kudziwa momwe amasiyanirana, ndi zosankha ziti zomwe zida zathu zimafunikira kuti tithe kuzigwiritsa ntchito:

1. HDR10 ndiye mtundu woyambira wa HDR ndipo umathandizidwa ndi ma TV onse kapena opanga zowonera ndi owulutsa (palibe chilolezo chomwe chimafunikira pankhaniyi). Mtundu wa HDR10 umagwiritsa ntchito mtundu wamtundu wa 10-bit (mitundu 1024 motsutsana ndi 220 pa TV wamba).
2. HDR10+ ndi mtundu wowongoleredwa malinga ndi metadata yogwiritsidwa ntchito – ndi yamphamvu. Kusindikizaku kumatengera mtundu wa 12-bit (mitundu yamitundu 4096), yopatsa zotsatira zabwinoko kuposa HDR10 yoyambira. Kusiyanitsa kulinso pakupulumutsa deta (mu mtundu wa Dolby Video, chimango chilichonse ndi fayilo yosiyana). Ndikofunika kuzindikira kuti ngati lusoli likuthandizidwa, mtengo wa TV umakwera.
3. Hybrid Log Gamma ndi mtundu wa HDR wopangidwa ndi British BBC (British Broadcasting Corporation) mogwirizana ndi NHK, wowulutsa dziko la Japan.

mawonedwe a HDR[/ mawu]

Vuto la ma TV achikhalidwe ndikuti ambiri omwe amawonera amangogwiritsabe ma TV akale a SDR omwe sangathe kuwonetsa mulingo wofala kwambiri wa HDR.

SDR nayonso ndiyotsika mtengo kwambiri popanga filimu, ndipo BBC mwachibadwa safuna kusiya mawonekedwe otsika mtengo omwe owonerera masauzande ambiri amadalirabe. Mawonekedwe a HLG amagonjetsa “chopinga” ichi polemba mauthenga onse a HDR ndi SDR mu siginecha imodzi, kulola ma TV ogwirizana ndi HDR kuti awonetse chithunzi chowongolera. Hybrid Log Gamma imagwiritsa ntchito zomwe zimadziwika kuti “opto-optical transmission function”, yomwe ndi njira yomwe imagwiritsidwa ntchito kusinthira siginecha yowulutsa kukhala yowala yomwe imawonetsedwa pa TV yanu.

Mukufuna chiyani kuti musangalale ndi chithunzi cha HDR?

Choyamba muyenera zida zoyenerera ndiyeno muyenera kujambula bwino. Chipangizocho chiyenera kukwaniritsa zofunikira zina. Muyenera kusamalira zinthu zotsatirazi:

• mufunika TV ya 8K kapena 4K yokhala ndi mapanelo amtundu wa 10-bit;
• kusiyana kwakukulu – kukwezeka kwabwinoko;
• kuwala 1000 cd / m^2 (mtengo wokwanira), koma kukwezeka kumakhala bwinoko.

Sony TV ndi mitundu ina yomwe imathandizira HDR ikhoza kukhala ndi zina zomwe zimakhudzanso mtundu wa kanema kapena masewera omwe mukuwonera, monga:

• 4K Ultra HD kusamvana – 3840 × 2160 pixels, chifukwa ngakhale zing’onozing’ono zimawoneka;
• cholumikizira cha HDMI 2.0 ndi yankho labwino powonera makanema kuchokera kuzinthu zina (chingwe chapadera chimagwiritsidwa ntchito polumikizana).

TV iyenera kukwaniritsa zofunikira zina (yang’anani chizindikiro cha UHD Premium) kuti chithunzi cha HDR chisakhale cholemera kwambiri kwa wolandira. Ngati wogwiritsa ntchito akufuna kuwonera makanema pa intaneti, kulumikizana kothamanga kwambiri kumafunika mpaka 25 Mbps. Kulumikizana kwa intaneti kwabwinoko, kumapangitsa kuti chithunzi chowulutsa chikhale bwino.

Kodi ndingapeze kuti zomwe zili mumtundu wa HDR?

Dongosolo la HDR mu ma TV ndi chinthu chamtengo wapatali chomwe chimapangitsa ogwiritsa ntchito ambiri kugula chitsanzo china chifukwa cha zopindulitsa zomwe zafotokozedwa. Amapangitsa kuonera mafilimu kukhala kosangalatsa kwenikweni, zithunzi zimakhala zomveka bwino, mitundu imakhala yowoneka bwino, ndipo zosiyana zimawonekera zomwe zimakhudza kawonedwe ka chithunzicho. Komabe, mukagula zida zanu, ndikofunikira kudziwa komwe mungayambire kuyang’ana makanema kuti akuthandizeni kuyesa luso la chipangizo chanu. Zosankha zingapo zomwe mungatsitse kapena kuwonera makanema ndi makanema mumtundu wa hdr:

1. 4K UHD Blu-ray discs . Wosewera wowonjezera amafunikira, zachilendo zilizonse zimawononga pafupifupi ma ruble 3,000.
