Chidziwitso Chachiyambi

UHD vs 4K

Nthawi zambiri mudzawona mawu akuti Ultra High Definition (kapena UHD) amagwiritsidwa ntchito mofanana ndi 4K. Izi sizolondola kwenikweni. UHD ndi mulingo wapa kanema wawayilesi, womwe umatanthauzidwa kukhala wokhazikika pawiri wa HDTV mu miyeso yonse iwiri. Full HD ndi 1920x1080, kotero UHD ndi 3840x2160.

4K, mosiyana, ndi liwu lochokera ku bizinesi yamakanema ndi kanema wamakanema a digito, ndipo limatanthauzidwa ngati mtundu uliwonse wazithunzi za digito wokhala ndi ma pixel opingasa 4096 (ndi mawonekedwe osunthika amasiyana malinga ndi mtundu wa chithunzi chaNspecific). Popeza 3840 ili pafupi kwambiri ndi 4096, nthawi zambiri mumawona mawu awiriwa akugwiritsidwa ntchito mosiyana. Tigwiritsa ntchito mawu oti "UHD" kutanthauza kanema wosungidwa pa 3840x2160 pixel resolution.

Zingwe za HDMI ndi Zolumikizira

Muyezo wa HDMI wasinthidwa nthawi zambiri, ndipo kusinthidwa kwatsopano kulikonse kumapangitsa kuti ma bitrate apamwamba athe kuwongolera kapena kuzama kwambiri pa pixel iliyonse. Zingakhale zovuta kudziwa kuti ndi zingwe zamtundu wanji za HDMI zomwe mukufuna, monga opanga zingwe nthawi zina amapereka nambala yowunikira ya HDMI yomwe imagwirizana nayo, kapena chiganizo, kapena chiganizo ndi kuzama pang'ono, kapena mawu osamveka ngati "amathandizira 4K. ”.

Kuti mupindule kwambiri ndi UHD & HDR ya Blu-ray Discs ndi kanema wa UHD yemwe akukhamukira pano, mudzafunika zingwe za HDMI zotha kudutsa magigabiti 18 pa sekondi imodzi (Gb/s). Ma chingwe omwe amakwaniritsa izi amalembedwanso kuti "HDMI 2.0" kapena apamwamba. Chingwe chilichonse cha HDMI chogwirizana ndi mtundu wa 2.0 chiyenera kukhala chabwino, koma yang'anani mawu omveka bwino kuti chingwecho chidavotera 18 Gb/s.

Osewera a UHD Blu-ray Disc

Izi zitha kuwoneka zomveka, koma kuti mugwiritse ntchito Ultra HD Benchmark, mufunika UHD Blu-ray Disc player! Mutha kupeza choyimira choyimira kuchokera ku LG, Sony, Philips, Panasonic kapena Yamaha, kapena mutha kugwiritsa ntchito Microsoft Xbox One X, One S kapena Series X, kapena Sony PlayStation 5 (Disc Edition). Samsung ndi Oppo ankakondanso kupanga osewera a UHD Blu-ray Disc, ndipo amatha kupezekabe atagwiritsidwa ntchito kapena ngati katundu wakale m'masitolo.

Ngati mulibe chosewerera cha Ultra HD Blu-ray Disc pano, tikupangira kupeza yomwe imathandizira Dolby Vision. Koma musadandaule ngati muli kale player popanda Dolby Vision; iyenera kugwira ntchito bwino ndi Ultra HD Benchmark.

Mawonekedwe a Ultra HD Panel vs. Projectors

Kuphatikiza pa makanema apakanema amakono, ochulukirachulukira owonera makanema ogula tsopano ali ndi malingaliro a 3840 × 2160 - kapena pafupifupi kuyerekezera kwake - komanso kuthekera kopanganso zomwe zili mumtundu wapamwamba kwambiri (HDR). Koma ma projekiti ogula sangakwaniritse paliponse pafupi ndi milingo yowala ya ma TV apansi panthaka, motero ayenera kulembedwa "Extended Dynamic Range" (kapena EDR) osati HDR. Komabe, ngakhale sangathe kutulutsa kuwala kofanana, amatha kuvomereza ndikuwonetsa ma siginecha a HDR, ndipo diski ya Ultra HD Benchmark ingagwiritsidwe ntchito kukhathamiritsa mapurojekitala komanso ma TV. Osayembekeza kuti HDR ikuwoneka ngati "yopunthwitsa" momwe ingachitire pagulu labwino lathyathyathya ngati chiwonetsero chamakono cha OLED.

Chinthu chimodzi choyenera kudziwa ndichakuti mapurojekitala a "UHD" kapena "4K" ali mkati mwake akugwiritsa ntchito gulu lotsika kwambiri la DLP kapena LCOS lomwe lilibe ma pixel owoneka bwino a 3840x2160. Zipangizozi zimatengera mawonekedwe apamwamba posintha mawonekedwe ocheperako pang'ono pang'ono mmbuyo ndi mtsogolo mwachangu pomwe akusintha chithunzi cha gululo mogwirizana ndi kusuntha kothamanga kwambiri. Athanso kusiya gululo ali m'malo mwake koma amasuntha chithunzicho pang'onopang'ono cha pixel mmbuyo ndi mtsogolo pawindo pogwiritsa ntchito kalilore kakang'ono kapena lens kwinakwake munjira ya kuwala. Zowonetserazi zili ndi chithunzi chabwinoko kuposa chowonetsera cha HD, koma osati chabwino kwambiri ngati chiwonetsero cha UHD chowona, ndipo makina osinthika amatha kupanga zinthu zachilendo. Nthawi zambiri, timalimbikitsa kumamatira ndi zowonetsa zomwe zili ndi gulu lenileni lomwe lili ndi malingaliro athunthu a UHD.

Momwe Mungayendere Mamenyu a Ultra HD Benchmark Disc

Pali ma discs atatu mu phukusi la Ultra HD Benchmark. Chimbale chilichonse chili ndi mindandanda yazakudya zosiyanasiyana komanso masinthidwe osiyanasiyana okhudzana ndi ma diski omwe ali pa diskiyo, koma onse ali ndi mawonekedwe ofanana ndipo amagwiritsa ntchito njira zazifupi zakutali.
Menyu yayikulu, kumanzere kwa zenera la menyu, ikuwonetsa zigawo zazikulu za disc. Magawo ambiri ali ndi tigawo tating'onoting'ono, tosanjidwa pamwamba pa chinsalu. Kuti mupite ku gawo, kanikizani muvi wakumanzere pa sewero lanu la Blu-ray Disc kutali mpaka gawo lomwe lilipo liwonetsedwe, kenako dinani muvi wopita mmwamba kapena pansi kuti mupite ku gawo lomwe mukufuna.

Kuti musunthire ku kagawo kakang'ono, kanikizani muvi wakumanja kuti musunthire chowunikira ku chimodzi mwazosankha zomwe zili patsamba lino, kenako dinani muvi wa mmwamba mpaka dzina lachigawo lomwe lili pamwamba pa chinsalu litsindikitsidwe. Kenako gwiritsani ntchito mivi yakumanzere ndi yakumanja kuti musankhe gawo lomwe mukufuna.

Mukasankha gawo lomwe mukufuna ndi kagawo kakang'ono, kanikizani muvi wapansi kuti musunthire zomwe zili patsamba lenilenilo, ndipo gwiritsani ntchito mivi inayi kuti musunthe ndikusankha pateni kapena kusankha. Gwiritsani ntchito batani la Enter (pakati pa mivi inayi pamiyala yambiri ya Blu-ray Disc player) kuti musewere mtunduwo kapena kusankha njirayo.

Njira zazifupi za Mu-Pattern

Ngakhale mawonekedwe akuwonetsedwa pazenera, mutha kugwiritsa ntchito muvi wolondola kuti musunthire pagawo lotsatira mkati mwa kagawo kakang'ono ka disc. Mutha kugwiritsa ntchito muvi wakumanzere kuti musunthire pateni yam'mbuyomu mgawoli. Mndandanda wamapangidwe agawo lililonse umazungulira mozungulira, kotero kukanikiza muvi wakumanja mukamawona mawonekedwe omaliza m'chigawochi kumapita kumtundu woyamba, ndipo kukanikiza kumanzere mukuwona mtundu woyamba m'chigawochi kumapita kugawo lomaliza.

Mukuwona mawonekedwe, mutha kukanikiza muvi wopita mmwamba kuti muwonetse menyu omwe ali ndi zosankha zamakanema komanso mawonekedwe apamwamba kwambiri. Gwiritsani ntchito mivi inayi kuti musankhe mtundu wa kanema, ndi kuwala kwapamwamba (pokhapokha ngati mavidiyo omwe asankhidwa ali HDR10). Kuti musiye menyu osasintha chilichonse, mutha kusankha mtundu womwe ulipo, kapena kukanikiza muvi wotsikira pansi kangapo mpaka menyuyo itachoka.

Pomaliza, poyang'ana machitidwe ambiri, mukhoza kukanikiza muvi wotsikira pansi kuti muwonetse zolemba ndi malangizo a chitsanzocho, kuphatikizapo malangizo a momwe mungatanthauzire ndondomekoyi, ngati chitsanzocho chili chothandiza pakusintha kwa maso. Zitsanzo zomwe zimapangidwira akatswiri okonza makina kuti azigwiritsa ntchito ndi zida zoyesera, zambiri zomwe zili mu gawo la Video Analysis, zilibe zolemba izi, chifukwa mafotokozedwe ake ndi ovuta kwambiri kuti agwirizane ndi tsamba limodzi la menyu.

Kukonzekera Sewero Lanu Lanyumba

Kulumikiza Player

Nthawi zonse timalimbikitsa kulumikiza Blu-ray Disc player (BD) mwachindunji ku TV, ngakhale mutakhala ndi AV Receiver yomwe imati imagwirizana ndi HDMI 2.0 ndi HDR. Ma AV Receivers ndi otchuka chifukwa chogwiritsa ntchito kukonzanso vidiyoyi, zomwe zimatha kusokoneza khalidwe komanso kumawonjezera zovuta kuti mufufuze zomwe zimayambitsa mavidiyo. Ngati n'kotheka, perekani chimodzi mwazolowetsa za TV yanu kugwero lanu lapamwamba kwambiri, sewero lanu la Blu-ray Disc, ngakhale mavidiyo anu ena onse akuyenda kudzera mwa wolandira wanu.

Ngati wosewera wanu wa BD ali ndi HDMI yachiwiri yotulutsa mawu, gwiritsani ntchito zomwezo kuti mulumikizane ndi AV Receiver kapena purosesa ya audio, ndi choyambira cha HDMI kuti mugwirizane ndi TV.

Ngati wosewerayo ali ndi chotulutsa chimodzi chokha, onani ngati TV ili ndi Audio Return Channel (ARC) kapena Enhanced Audio Return Channel (eARC) HDMI zolowetsa ndipo AV Receiver yanu ili ndi ARC kapena eARC HDMI zotuluka. Ngati ndi choncho, mutha kuyatsa ARC kapena eARC pazida zonse ziwiri, ndikupangitsa kuti TV itulutse mawuwo pa siginecha ya HDMI yophatikizidwa ndikuyitumizanso kwa wolandila. Kwenikweni, eARC imapereka mwayi wotumiza zomvera za TV "kumbuyo" pa chingwe cha HDMI cholumikizidwa ndi AV Receiver. Kenako mutha kulumikiza sewero la Blu-ray Disc kapena bokosi lokhamukira kuzinthu zina pa TV, ndipo TV imatumiza mawuwo kudzera pa eARC, kubwerera kwa wolandila. Kanema + wophatikizidwa amachoka kwa wosewera mpira kupita ku TV pa imodzi mwa njira zolowera pa TV, ndiyeno mawuwo amabwerera ku AV Receiver pa njira ina yolowera pa TV (yomwe pakadali pano imakhala yotulutsa mawu - zosokoneza pang'ono!)

Mwachitsanzo, tiyerekeze kuti wolandirayo ali ndi eARC pazotulutsa zake za HDMI 1, ndipo TV ili ndi eARC pazolowetsa zake za HDMI 2. Mutha kulumikiza chotulutsa cha HDMI 1 cha AV Receiver ku HDMI 2 ya TV, ndikugwiritsa ntchito mindandanda yazida zonse ziwiri kuti mutsegule eARC. Mungakhazikitse wolandila ku zolowetsa za eARC (nthawi zina zimatchedwa "TV"). Kenako mungalumikize zotulutsa za Blu-ray Disc player kuzinthu zina pa TV, mwachitsanzo kulowetsa kwa TV kwa HDMI 1. Ngati muli ndi zipangizo zina zolumikizidwa ku AV Receiver pa zolowetsa zina zolandirira, simungagwiritse ntchito eARC pazida zimenezo - mungasinthire cholandiracho kupita ku tchanelo cha HDMI chomwe zidazo zimalumikizidwa, ndikukhazikitsa TV ku HDMI 2. Zikatero, eARC sikugwira ntchito ndipo tcheni cha siginecha chimakhala chowongoka: Chida Chosewera -> Wolandila -> TV.

Ngati chimodzi mwazosankhazi sichingagwire ntchito ndi zisudzo zakunyumba kwanu, mungafunike kuwongolera zomwe wosewera wanu akutulutsa kudzera pa AV Receiver yanu kuti nyimboyo izisewera. Ngati mupeza mavidiyo akale pamene mukuyesa ndikusintha, lingalirani zolumikizira kwakanthawi wosewerayo ku TV kuti muwone ngati zinthuzo zimayambitsidwa ndi AV Receiver. Ngati zili choncho, mwina mudziwa ndipo mutha kuziyika mu mapulani anu okweza zisudzo zamtsogolo.

Onetsetsani kuti mukugwiritsa ntchito zingwe za HDMI zovotera 18Gb/s kapena kupitilira apo, ndi/kapena HDMI 2.0 kapena kupitilira apo. Mumangofunika zingwe za HDMI za giredi iyi kuti mulumikizane ndi wosewera mpira kupita ku TV ngati kanemayo akudumpha wolandila ndikupita ku TV. Ngati vidiyoyi imayendetsedwa kudzera pa wolandila kapena bokosi lachiwiri losinthira, zingwe zochokera kwa wosewera mpira kupita kwa wolandila kapena switchbox ndi zingwe zochokera ku wolandila kapena switchbox kupita ku TV ziyenera kukhala 18Gb/s.

Kutsegula Makanema Otsogola pa TV

Ma TV ambiri amafika ndi zinthu zingapo zoyimitsidwa zomwe mungafune kuyatsa, monga ma bitrate apamwamba, mtundu wowonjezera wamtundu kapena Dolby Vision. Ena amangoyatsa izi ngati awona kuti chipangizo chomwe chingawagwiritse ntchito chalumikizidwa, ena adzakudziwitsani kuti muyenera kuyatsa zinthuzi, ndipo ena amangokana kulola kulumikizana ndi izi mpaka mutayatsa pamanja.

Pansipa pali chitsogozo chothandizira izi pazinthu zingapo wamba zapa TV. Mawonekedwe a TV amatha kusintha chaka ndi chaka, kotero kupeza zosinthazi kungaphatikizepo kuyang'ana pang'ono pamindandanda kapena kuwerenga magawo ofunikira a kalozera wa ogwiritsa ntchito pa TV yanu:

Choyamba, sankhani mawonekedwe azithunzi za Cinema, Movie kapena Filmmaker, zomwe nthawi zambiri zimakhala zolondola kwambiri zakunja. Zokonda pazithunzizi nthawi zambiri zimapezeka pazithunzi zazithunzi.

Ma TV ena ali ndi ma Cinema opitilira imodzi; mwachitsanzo, ma TV ena a LG osasintha ku Cinema Home, koma mawonekedwe otchedwa Cinema ndi abwino kwambiri. Mukhoza kutsimikizira izi mwa kusonyeza chitsanzo cha HDR Color Space Evaluation ndikuyang'ana pa gawo la ST2084 Tracking (onani mkuyu 4). Rectangle iliyonse mu gawolo imawoneka imvi yolimba-monga momwe iyenera kukhalira-mukasankha mawonekedwe a Cinema mu 2018 kapena 2019 LG TV. Momwemonso, njira yabwino kwambiri mu ma TV a Sony imatchedwa Cinema Pro.

Chotsatira, onetsetsani kuti kutentha kwa utoto kumayikidwa Kutentha, komwe nthawi zambiri kumakhala kolondola kwambiri pakatentha. Makina azithunzi a Cinema nthawi zambiri amakhala osasintha pamakonzedwe awa, koma ndibwino kuwunika kawiri. Makina otenthetsera utoto nthawi zambiri amapezeka ozama pazithunzi za Chithunzichi mu gawo la "zotsogola".

Ma TV ambiri a Sony ndi Samsung amapereka magawo awiri Otentha: Warm1 ndi Warm2. Sankhani Warm2 ngati sakugwira ntchito kale. Komanso ma TV a Vizio atsopano alibe malo ofunda konse; Zikatero, sankhani Normal.

Kuyika kwina kofunikira koyang'ana nthawi zambiri kumatchedwa Kukula kwa Chithunzi kapena Aspect Ratio. Zosankha zomwe zilipo pazochunirazi zimaphatikizapo 4:3, 16:9, zochunira imodzi kapena zingapo zotchedwa Zoom, ndipo mwachiyembekezo, ina yotchedwa Dot-by-Dot, Just Scan, Full Pixel, 1:1 Pixel Mapping, kapena zina. monga choncho. Mapangidwe okhala ndi dzina ngati omalizawo amawonetsa pixel iliyonse pazomwe zikuyenera kukhala pazenera, zomwe ndi zomwe mukufuna.

Chifukwa chiyani pali makonda omwe samawonetsa pixel iliyonse pazomwe ikuyenera kukhala pazenera? Zosintha zambiri zimasokoneza chithunzicho kuti chidzaze zenera, kusuntha ma pixel mozungulira komanso kupanga ma pixel atsopano kuti atero. Ndipo makonda ena amatambasulira chithunzicho pang'ono pang'ono mwanjira yotchedwa "overscanning," yomwe idagwiritsidwa ntchito mu ma TV a analogi kubisa zambiri m'mphepete mwa chimango chilichonse chomwe chimayenera kukhala chosawoneka kwa owonera. Izi ndizosafunikira m'zaka za digito ndi ma TV, koma opanga ambiri amachitabe.

Pazochitika zonsezi, njira yotambasula chithunzicho-yomwe imatchedwa "kukweza" - imachepetsa chithunzicho, kuchepetsa tsatanetsatane womwe mungawone. Kuti mupindule kwambiri ndi Benchmark ya Ultra HD, muyenera kuwonetsetsa kuti makulitsidwe aliwonse, kuphatikiza kuwonjeza, kwayimitsidwa. Sankhani Dot-by-Dot, Just Scan, Full Pixel, kapena chilichonse chomwe TV yanu imatcha 1:1 pixel mapu.

Ma TV a Hisense ali ndi Kukula Kwazithunzi ndi Magawo Overscan. Chotsani Overscan ndikukhazikitsa Kukula kwa Chithunzi ku Dot-by-Dot.

Kuti muwonetsetse kuti mwayimitsa makulitsidwe onse, onetsani Chitsanzo Chotsitsa Zithunzi, chomwe chimapezeka mumndandanda wa Advanced Video-> Evaluation. Choyang'ana cha pixel imodzi chikuwonekera pakati pa chitsanzocho. Ngati makulitsidwe/kuwonjezanso kwazimitsidwa, bolodi loyang'ana limawoneka ngati imvi. Apo ayi, checkerboard idzakhala ndi zosokoneza zachilendo zotchedwa "moiré." Mukasankha mapu a pixel 1: 1, moiré iyenera kutha.

Ma TV a OLED nthawi zambiri amakhala ndi ntchito yotchedwa "orbit," yomwe imasunthira chithunzi chonse mmwamba, pansi, kumanja, ndi kumanzere ndi pixel imodzi kamodzi pakanthawi kuti achepetse mwayi wosunga chithunzi kapena "kuwotcha".

Ngati izi zitayatsidwa - zomwe nthawi zambiri zimakhala mwachisawawa - mapeto a imodzi mwamakona anayi amtundu wa Image Cropping olembedwa "1" sangawonekere. Zimitsani kanjirako kuti muwonetsetse kuti mukuwona makona anayi onse olembedwa "1."

Kenako, onetsetsani kuti zonse za TV zomwe zimatchedwa "zowonjezera" ndizozimitsidwa. Izi zimaphatikizapo kumasulira kwa chimango, kukulitsa kwamtundu wakuda, kusiyanitsa kwamphamvu, kukweza m'mphepete, kuchepetsa phokoso, ndi zina. Zambiri mwa "zowonjezera" izi zimanyozetsa chithunzithunzi, choncho zimitsani nthawi zonse.

Pamitundu yosinthira, mawonekedwe a gamma akuyenera kukhala pafupi ndi 2.4 momwe angathere. Popanda ukadaulo kwambiri, gamma imazindikira momwe chiwonetserochi chimayankhira pamakhodi osiyanasiyana owala mu siginecha yamavidiyo. Mayeso a SDR amadziwika ndi gamma ya 2.4, kotero ndizomwe chiwonetserocho chiyenera kukhazikitsidwa.

Monga momwe mungayembekezere pofika pano, opanga osiyanasiyana amafotokozera mawonekedwe a gamma mosiyana. Ena amatchula mtengo weniweni wa gamma (mwachitsanzo, 2.0, 2.2, 2.4, ndi zina zotero), pamene ena amatchula manambala osagwirizana (monga 1, 2, 3, etc.). Ngati sizikudziwikiratu kuti mtengo weniweni wa gamma umachokera ku dzina lomwe lili m'mindandanda, ndibwino kungosiya.

Basic Player Zikhazikiko

Osewera a Ultra HD Blu-ray amapereka zowongolera zawo zomwe muyenera kuyang'ana. Tsegulani menyu ya wosewerayo ndikuwona ngati ili ndi zowongolera zosintha zithunzi (monga kuwala, kusiyanitsa, mtundu, kupendekera, kuthwa, kuchepetsa phokoso, ndi zina). Ngati ndi choncho, onetsetsani kuti zonse zakhazikitsidwa ku 0/Off. Zowongolera zonsezi ziyenera kusinthidwa pa TV, osati osewera.

Pafupifupi osewera onse amapereka chiwongolero chowongolera, chomwe kwa osewera ambiri chiyenera kukhala UHD/4K/3840x2160. Izi zipangitsa kuti wosewerayo akweze malingaliro otsika ku UHD, komwe ndikusintha kwazinthu zambiri pa Ultra HD Benchmark, kotero itumizidwa kuwonetsero osasinthidwa. Kwa owerengeka ochepa omwe ali ndi "gwero lachindunji" lomwe lingatumize chizindikirocho pamalingaliro amtundu wa UHD ndi HD magwero, pitilizani kugwiritsa ntchito njirayo.

Kuphatikiza apo, osewera ena a Ultra HD Blu-ray - monga ochokera ku Panasonic - ali ndi luso lojambula mapu a HDR asanatumizidwe kuwonetsero. Mu osewera a Panasonic, komabe, kutembenuza izi kumayambitsa ma banding mumayendedwe ena oyesa pa Ultra HD Benchmark. Chifukwa chake, ndibwino kuletsa izi mukamagwiritsa ntchito Ultra HD Benchmark.

Ngati wosewera wanu ali ndi malo amtundu komanso zowongolera mozama, poyambira bwino ndikuyiyika kukhala 10-bit, 4:2:2. Pambuyo pake, mutha kugwiritsa ntchito mtundu wa Colour Space Evaluation kuti muyese malo ena amitundu ndikuwona ngati mupeza zotsatira zabwinoko ndi malo amtundu wosiyana kapena kuzama pang'ono.

Ngati wosewera wanu amathandizira Dolby Vision, onetsetsani kuti yayatsidwa. Ngati pali mwayi wosankha wosewera kuti asankhe "wotsogolera-wosewera" kapena "wotsogozedwa ndi TV" Dolby Vision processing, muyenera kuyiyika kuti "yotsogozedwa ndi TV." Izi zimatsimikizira kuti chidziwitso cha Dolby Vision chimatumizidwa ku TV osakhudzidwa.

Zambiri zowongolera zithunzi mu wosewerayo ziyenera kusakhazikika kukhala "auto," zomwe zili bwino. Kutengera wosewera mpira, izi zitha kuphatikiza chiŵerengero cha mawonekedwe, 3D, ndi deinterlacing.

Kusintha kwa Disc 1

Pali zigawo zinayi zazikulu pawonekedwe la Disc 1 Configuration: Format Video, Peak Luminance, Audio Format, ndi Dolby Vision (analysis).

Choyambirira komanso chofunikira kwambiri ndi "Mtundu wa Video,” yomwe ikhoza kukhazikitsidwa ku HDR10, HDR10+, kapena Dolby Vision. Mudzawona cholembera pafupi ndi akamagwiritsa kuti wosewera mpira ndi TV lipoti kuti amathandiza. Ngati mukuyembekeza kuwona cholembera pafupi ndi mtundu koma osawona, mungafune kuwonetsetsa kuti mawonekedwe omwe akufunsidwawo amathandizidwa ndi osewera komanso TV, komanso kuti amathandizidwa pazida zonse ziwiri. Zindikirani kuti ma TV ena amakulolani kuti muzitha kusankha kapena kuletsa mawonekedwe pazomwe mukulowetsa, choncho onetsetsani kuti zolowetsa za HDMI zomwe mukugwiritsa ntchito zili ndi mtundu womwe mukufuna kugwiritsa ntchito. Ngati mukukhulupirira kuti zidazo zimagwirizana ndi mtunduwo, mutha kusankha mtunduwo ngakhale simukuwona cholembera pafupi nacho.

Pakadali pano, ikani Kanema Format kukhala HDR10. Pambuyo pake, mutha kubweza ndikubwerezanso ma calibrations ndi makanema ena omwe bwalo lanu lanyumba limathandizira.

Chotsatira chiri Peak Luminance. Mawonekedwe a Kanema akakhazikitsidwa kukhala HDR10, mulingo wapamwamba kwambiri wowunikira ukhoza kusinthidwa ndi menyu iyi. Muyenera kuyika izi kuti zifanane kwambiri ndi mawonekedwe anu apamwamba kwambiri. Ngati simukudziwa momwe chiwonetsero chanu chikuwonekera kwambiri, chowonetsera chathyathyathya, chikhazikitseni ku 1000, kapena purojekitala, ikani ku 350.

Chepetsani kuwongolera kwa Makatanidwe a TV mpaka makona onse awonekedwe. Ngati simungathe kupangitsa kuti makona onse awonekere, ngakhale atakhala otsika bwanji Contrast, tsitsani mpaka makona ambiri momwe mungathere awonekere.

Mukakhala ndi makona onse owoneka (kapena ochuluka momwe mungathere), onjezani chowongolera mpaka kakona kakang'ono kamodzi kazimiririka, ndiye tsitsani notch imodzi kuti mubweretsenso makona anayi omwe angosowa.

Mawonekedwe

Kuwala ndikuwongolera komwe ndikofunikira kwambiri kuti mupeze chithunzi choyenera. Mosiyana ndi makonda ambiri azithunzi, ilibe mawonekedwe olondola. Kuyiyika nthawi zonse kumakhudza momwe mumaonera, ndipo imakhudzidwa ndi mtunda womwe mumawonera, kukula kwa chiwonetsero chanu, komanso kuwona kwanu.

Njira yayikulu yokhazikitsira Sharpness ndikuyitsitsa mpaka zinthu zakale ziwonekere, kenako ndikuzitembenuza mpaka zinthuzo zitasiya kuwonekanso. Cholinga chake ndikupangitsa chithunzicho kukhala chakuthwa momwe mungathere popanda kuyambitsa zovuta zazithunzi.
Kuti muwone zina mwazithunzi zosasangalatsazo, yambani ndikuwonetsa mawonekedwe a Sharpness pazenera. Tsopano tembenuzirani kuwongolera kwanu kwa Sharpness mpaka pansi, ndiye mpaka mmwamba. Khalani omasuka kuti musunthe mmbuyo ndi mtsogolo kuchokera pamwamba mpaka pansi pamene mukuyang'ana chitsanzo. Mungafunike kuyandikira pafupi ndi chinsalu kuti muwone zomwe zikuchita pachithunzichi momveka bwino (koma osayang'anira Kuwala muyimirira pafupi ndi chinsalu).

Zinthu zakale zomwe muyenera kuziwona ndi izi:

• Moire - izi zikuwoneka ngati ma contour abodza ndi m'mphepete m'mbali zatsatanetsatane zazenera. Pazigawo zina zatsatanetsatane za chitsanzocho, zingakhale zosatheka kuthetsa moiré ngakhale Sharpness imayikidwa motsika momwe mungathere, koma nthawi zambiri padzakhala mfundo yaikulu mumtundu wa Sharpness kumene moiré amakhala wamphamvu komanso wosokoneza.

• Kulira - ichi ndi chojambula chomwe chimawoneka ngati mizere yofiyira yakuda kapena yoyera pafupi ndi m'mphepete mwakutali kwambiri. Nthawi zina pamakhala mzere umodzi wowonjezera, ndipo nthawi zina zingapo. Ndi Sharpness itatembenuzika mpaka pansi, simuyenera kuwona mizere yowonjezera iyi, ndipo itakhazikika njira yonse, mizere yowonjezerayo ikuwoneka bwino.

• Makwerero - Pamphepete mwa diagonal ndi zokhotakhota zosazama, mutha kuwona m'mphepete mwake ngati mabwalo ang'onoang'ono okonzedwa ngati masitepe, m'malo mwa mzere wabwino wosalala kapena wopindika. Ndi Sharpness mpaka pansi, izi ziyenera kukhala zochepa, ndipo mpaka mmwamba, mudzaziwona pamizere yambiri pachithunzichi.

• Kufatsa - Ichi ndi chojambula chomwe chimachitika pamene Sharpness imakhala yotsika kwambiri. Mphepete mwa nyanja imasiya kuwoneka yakuthwa komanso yowoneka bwino. Malo atsatanetsatane monga ma checkerboards ndi mizere yofananira amakhala osamveka bwino.

Mukangomva ngati mukudziwa kuti ndi zinthu ziti zomwe zimawoneka ndi chiwonetsero chanu komanso Sharpness control yanu, bwererani pamalo anu okhala.

Tsopano, ikani Sharpness mpaka pansi pamtundu wake. Kenako sinthani Sharpness mpaka mutayamba kuwona zinthu zakale, kapena mpaka ziwonekere kwambiri. Kenako chepetsani Kuthwanima mpaka zinthuzo zitachoka kapena zili zofewa, mwachiyembekezo musanayambe kuwona kufewa kwa chithunzi.

Ndi ma TV ena, pangakhale mfundo yomveka bwino yomwe kufewa kumachepetsedwa ndipo zopangira sizipezeka kapena zosavutitsa. Ndi ena, mungapeze kuti muyenera kuvomereza kufewa pang'ono kuti mupewe zinthu zina zakale, kapena muyenera kuvomereza zinthu zazing'ono kuti muchotse zofewa. Mutha kupezanso kuti zomwe mumakonda za zomwe zimakwiyitsa kwambiri zitha kusintha mukawonera zomwe zili pa TV yanu. Ndibwino kuti muyang'anenso maulamulirowa kangapo, mutatha nthawi yambiri mukuwonera zinthu zabwino ndikuwona mavidiyo amtundu wanji.

Ma TV ambiri amakono ali ndi zoikamo ndi mitundu ingapo yomwe ili yamitundu yosiyanasiyana yakuthwa bwino, ndipo njira iyi ndi yoyenera kuwunika zonse. Nawa makonda ndi mitundu ingapo yomwe ili pamtima mtundu wina wakunola kapena kufewetsa. Ndibwino kuyesa onsewo mukuwona mawonekedwe a Sharpness kuti muwone zomwe akuchita pachithunzichi. Monga momwe zimakhalira ndi Sharpness control, zisintheni mpaka zitapanga chithunzi chowoneka bwino chokhala ndi zinthu zochepa zosokoneza.

Mawonekedwe apamwamba kwambiri omwe amagwiritsidwa ntchito m'makampani onse amapangidwa ndi ma 8 bits olondola, ngakhale lero pomwe kanema wa 10-bit amagwiritsidwa ntchito kwambiri pa HDR pa disc ndi kusanja. Izi sizingawoneke ngati vuto lalikulu, koma zimabweretsa zolakwika, zina zomwe zitha kuwoneka, ndipo zonse zimakhudza zida zoyezera. Tawonanso ma disc amakono oyesera akugwiritsa ntchito zithunzi za 8-bit master kusinthidwa kukhala 10-bit pochulukitsa ma pixel onse.

Sizingawoneke ngati 2 zowonjezera zowonjezera zingakhale zofunikira kwambiri, koma zowonjezera ziwirizo zimachulukitsa kanayi chiwerengero cha magawo osiyana omwe amatha kuwonetsedwa muzitsulo zofiira, zobiriwira ndi zabuluu, ndipo izi zingathe kuchepetsa zolakwika. .

Mwachitsanzo, tiyerekeze kuti tikufuna kupanga 50% imvi zenera (ichi ndi 50% stimulus, yomwe ili yosiyana ndi 50% mzere - zambiri pambuyo pake). Mtengo wa 0% mu 8-bit ndi 16, ndipo mtengo wa 100% ndi 235, kotero 50% idzakhala (16 + 235) / 2, yomwe ndi 125.5. Nthawi zambiri izi zimazungulira mpaka 126, koma mwachiwonekere ndizokwera kwambiri. 125 Zingakhale zotsika kwambiri. 126 imachokera ku 50.23%, chomwe ndi cholakwika chachikulu ngati mukuyesera kupeza miyeso yolondola kwambiri kuti muyike bwino kwambiri. Mosiyana ndi izi, pogwiritsa ntchito ma code 10-bit, mutha kuyimira ndendende 50% ngati mtengo wa code, popeza mu 10-bit mtunduwo ndi 64 940, ndi (64 + 940) / 2 = 502.

Ngakhale 50% imatuluka bwino mu 10 bits, 51% samatuluka, komanso 52% kapena 53% kapena mulingo wina uliwonse kupatula 0% ndi 100%. Kugwiritsa ntchito ma bits 10 athunthu kumachepetsa cholakwikacho, koma ngati cholinga chanu ndikuyandikira ungwiro momwe mungathere, mukufunadi kukankhira cholakwikacho momwe mungathere, ndipamene dither imalowa.

Pamene mita yowala kapena colorimeter imayeza zenera kapena chigamba pazenera, sikuyesa mtengo wa pixel imodzi, ikuyesa bwino ma pixel mazana ambiri omwe amagwera mkati mwa bwalo lake. Posintha mulingo wa ma pixel mubwalo loyezera, titha kupanga zenizeni zenizeni ndi zolakwika zosawerengeka. Mwachitsanzo, ngati tikufuna mulingo womwe umagwera ndendende pakati pa code value 10 ndi code value 11, titha kupanga zenera lathu kukhala lobalalika mwachisawawa pomwe theka la ma pixel ali pa code 10 ndi theka pa code 11, yomwe imayeza ndendende. pakati pa kuwala koyembekezeredwa kwa code 10 ndi code 11. Zomwezo zimagwiranso ntchito pa kulondola kwa mtundu; podutsa pakati pa mitundu yosiyanasiyana yapafupi tikhoza kugunda pafupi kwambiri momwe tingathere kuti tigwirizane ndi mtundu womwe tikufuna kusonyeza.

Linear vs. Stimulus (% code value) Miyezo
Iyi ndi nthawi yabwino yosiyanitsa pakati pa magulu osiyanasiyana. Mwinamwake mwawonapo m'machitidwe athu kapena malemba othandizira kuti ndondomeko ili pa "50% code value" kapena "50% linear" ndipo pokhapokha ngati muli ndi mbiri ya kanema kapena mtundu wa malingaliro zingakhale zovuta kumvetsa kusiyana kwake. Nayi (kwambiri) kalozera wachangu:

Pafupifupi mitundu yonse ya mawonedwe a digito ndi zojambula zomwe zimagwiritsidwa ntchito masiku ano, pali chinachake chotchedwa "transfer function" yomwe imapanga mapu omwe amatumizidwa kuwonetsero ("mawu a code") ku miyeso yeniyeni ya kuwala yomwe imapangidwa mwakuthupi ndi chiwonetsero ("code word" values) "Linear" mfundo). Mu kanema wa Standard Dynamic Range (SDR), ntchito yosinthira ndi njira yosavuta yokhotakhota, pomwe L = SG, pomwe L ndi Luminance yofananira, S ndi mtengo wolimbikitsira wopanda mzere, ndipo G ndi gamma. Mu kanema wa HDR, ntchito yosinthira imakhala yovuta kwambiri, koma ikadali ngati njira yosavuta yamagetsi.

Ntchito yosinthira imagwiritsidwa ntchito pojambula chifukwa imatengera malingaliro amunthu pakusintha kwa kuwala. Maso anu amakhudzidwa kwambiri ndi kusintha kwa mulingo wa kuwala kumapeto kwenikweni kwa sikelo yowala kuposa kumapeto kwapamwamba. Chifukwa chake, pogwiritsa ntchito curve iyi kuyimira milingo ya kuwala, zithunzi zojambulidwa kapena kanema zitha kuyika ma code ambiri pafupi ndi zakuda, pomwe zikufunika, komanso zocheperako pafupi ndi zoyera, pomwe sizikufunikanso. Kuti ndikupatseni lingaliro la momwe zimagwirira ntchito, mu kabisidwe ka 10-bit HDR, kuchoka pamtengo wa 64 mpaka 65 kumayimira kusintha kwa mulingo wowunikira wa 0.00000053%, pomwe kuchoka pa code 939 kupita ku 940 kumayimira kusintha kwa 1.085 %.

Ngati izo zikupweteka mutu wanu, musadandaule, ndizovuta pang'ono kukulunga mutu wanu mozungulira. Zotsatira zake ndikuti, titi, 25% chokondoweza sichiri theka lowala ngati 50% stimulus, osachepera mayunitsi thupi kuyeza ndi mita kuwala. Mungapeze, malingana ndi ntchito yeniyeni yosinthira yomwe ikugwiritsidwa ntchito, kuti 25% yotsitsimutsa ikuwoneka pafupifupi theka lowala ngati 50% stimulus, chifukwa cha kusiyana kotchulidwa kale kwa malingaliro m'maganizo aumunthu, koma diso laumunthu silimayesa kuwala. ngati mita ya kuwala.

Chinthu chinanso chofunikira kudziwa ndichakuti ndi HDR yamakono, ndizofala kwambiri kupereka mizere yamayunitsi owunikira, operekedwa ngati "ma candela pa mita squared" kapena "cd/m2". (Dzina lodziwika bwino la unit iyi ndi "nits," ndiye ngati mungawone "1000 nits" ndiye chidule cha "1000 cd/ m2".)

Mukawona manambala pamapangidwe athu, ngati muwona mawu oti "mizere" kapena kuwona kuti mayunitsiwo ndi cd/m2, mutha kukhala otsimikiza kuti manambalawo ndi a mzere ndipo amayimira kuchuluka kwa thupi komwe mungathe kuyeza.

Ngati muwona ma code, kapena kuwona zolemba ngati "% code value" kapena "% stimulus" kapena ngakhale maperesenti opanda woyenereza, pafupifupi nthawi zonse ndi manambala olimbikitsira, omwe sapanga mapu motsatana ndi milingo yeniyeni yoyezera.

Kusiyanitsa kwakukulu pakati pa izi ndikuti mukamawirikiza kapena kuchepetsa kuchuluka kwa zolimbikitsa zomwe zaperekedwa kapena mtengo wa code, kuwala koyezera sikumawirikiza kawiri kapena theka, koma kudzasintha malinga ndi momwe mukusinthira. Ndipo ndi ntchito zamakono zosinthira HDR, kuwirikiza kawiri kolimbikitsa kumatha kuyimira kuwirikiza kawiri kwa kuwala kwa mzere, kotero malingaliro anu okhudza momwe chokondolera chimodzi chikuyenera kukhalira chogwirizana ndi china chingakhale cholakwika. Osadandaula; izi ndizabwinobwino ngakhale kwa anthu omwe amagwira ntchito ndi makanema nthawi zonse.

Pansipa pali tebulo lomwe likuwonetsa mgwirizano pakati pa mizere yowunikira (mu cd/m2), kuchuluka kwa mzere wokhazikika, kuchuluka kwa zokoka, ndi mtengo wapafupi wa ma code 10-bit mulingo wocheperako.
