Ndi chitukuko chofulumira chaukadaulo waukadaulo ndi ma codec, kuti mukwaniritse bwino malo olamulira, malo opangira data ndi mayankho ena akulu akulu amawu ndi makanema.
Kufunika kwa njira yolumikizirana, dongosolo logawa limabuka.
LED ili ndi maubwino ambiri chifukwa cha kusokera kwake kopanda msoko, masanjidwe ake osinthika, komanso mawonekedwe abwino kwambiri amitundu pamawonekedwe omwe amagawidwa.
Ndiye chifukwa chake dongosolo logawika lachikhalidwe lidzawoneka mavutowa, ndi Nova [dongosolo logawira mphamvu zakumwamba] kudzera muzoyesayesa zotani, kuti apereke masewera owonetsera ubwino wa LED, kuti akwaniritse kumvetsetsa kwa LED kugawidwa.
Traditional anagawa dongosolo
Pakadali pano, njira yodziwika bwino pamsika imagwiritsa ntchito njira yapakatikati ya H264 / H265 kuti iphanikiza chizindikiro choyamba cha kanema wa HD mumsewu wama network.Ngakhale kuti chiŵerengero chapamwamba cha kuponderezana chimachepetsa kwambiri kufunikira kwa bandwidth yotumizira, zovuta zake zikuwonekeranso kwambiri.
Kuipa: ①: otsika psinjika khalidwe kumabweretsa lalikulu chithunzi kutayika khalidwe
The psinjika chiŵerengero cha muyezo mwakuya psinjika aligorivimu akhoza kufika nthawi 50-300, ndi mkulu psinjika chiŵerengero ayenera kubweretsa imfa ya chithunzi khalidwe.Kugawa kwachikhalidwe nthawi zambiri kumangothandizira 8bi t 4:2 ∶ 0 kukonza, zomwe zimapangitsa kuti pakhale mawonekedwe osakwanira amitundu yonse yogawidwa, makamaka pazithunzi ndi mitundu yakumbuyo yakumbuyo, pazowonetsera.
Zoipa.②:akuwonetsa kuchedwa kwakukulu
H.264/H.265 The inter frame compression aligorivimu imayambitsa kuchedwa kwa mafelemu 2-3 pa decoding ndi encoding.Kuphatikiza pa chikoka cha njira yopatsirana, kukonza zithunzi ndi magawo ena, kuchedwa kwa zinthu zina kumapitilira 120ms, ndipo pali kuchedwa kodziwikiratu komanso kuchedwa, komwe kumachepetsa kwambiri zomwe wogwiritsa ntchitoyo akuchita.
Zoyipa ③: splicing lalikulu chophimba kulunzanitsa ndi osauka, wamphamvu misozi mphamvu
Kulondola kwachikhalidwe komwe kumagawika ndikotsika, kupatuka kwapakati pa node nthawi zambiri kumakhala mazana a ife kapena ngakhale mulingo wa ms, ndipo mawonekedwe olumikizirana sali okhazikika mokwanira, zomwe zimapangitsa kuti chiwonetsero chazithunzi chikhale chosatsimikizika.
Chochitika chong'ambika, chomwe sichimangowoneka ndi maso, koma chowonekera kwambiri pojambula zithunzi, chimakhudza kwambiri mawonekedwe a chiwonetsero cha LED.
Zoyipa ④: Chigamulo chokhazikika chokha ndichothandizira
Chifukwa cha mawonekedwe ake osinthika komanso osasinthasintha, ma LED nthawi zambiri amakhala ndi zosankha zapadera zomwe sizinali zokhazikika.Ndipo chiwonetsero chachikhalidwe chomwe chimagawidwa chimagwiritsidwa ntchito kwambiri pakuwonetsa makristalo amadzimadzi
Apa, pongothandizira kusamvana kokhazikika, monga 1920 * 1080,2048 * 1536, sakhala ochezeka mokwanira kuti athandizire kusamvana kwapadera komanso kusinthika kwa LED.Popanga
Pakhoza kukhala molingana kupotoza ndi zina, ndipo ngakhale kufunika angapo splicing, amene osati kumawonjezera mtengo kasitomala, komanso kwambiri zimakhudza wosuta zinachitikira.
[Tianquan Distributed System] imatengera HEVC Plus compression algorithm, kuphatikiza 10bit 4 ∶ 4, ulalo wathunthu 4K@60Hz, nanosecond synchronization, ndikuwonetsa kuchokera
Fotokozani ndi ntchito zina zomaliza, sungani bandwidth yotsika ndikusunga zambiri, kuchokera pamtundu wa chithunzi, kulunzanitsa, kuchedwa ndi kuyesa kupuma, kusalala ndi miyeso ina, kutumiza kwathunthu
Chotsani mawonekedwe a LED.
10bit 4:4:4 chithunzi chachilengedwe chimakhala ngati moyo
Nova NSMC wanzeru chithunzi encoding luso, kuphatikizika ndi wapadera hardware nsanja, zogwirizana mokwanira HFR codec, akhoza kuthandizira mpaka 120Hz mpumulo mlingo,Kujambula ndikuwonetsa makanema othamanga kwambiri kumamveka bwino.Nthawi yomweyo, NSMC imathandizira 10bit 4: 4 processing, kutsindika Smart Detect, kudzera pakompyuta
Kuzindikira, kufananiza kwa histogram ndi algorithm yozindikiritsa m'mphepete, kusiyanitsa kwanzeru pakati pa zochitika zachilengedwe ndi zolemba, kusintha kosinthika kwa codec algorithm, ndi singano.
Kuphatikizika kwa zithunzi zogonana, kuchepetsedwa, kotero kuti kuchepetsedwa kwa utoto kumakhala kowona komanso kolondola, sikelo yotuwira pang'onopang'ono imasintha komanso yosalala, imathandizira BT2020, imagwirizana ndiChiwonetsero cha LEDmawonekedwe, kuti mukwaniritse HDR.
Kukonza mawu kwachikhalidwe
Kusintha kwa mawu a NMSC
Pambuyo pa Nova NSMC wanzeru chithunzi code code processing lemba: chroma zambiri amakhalabe;Bwezeretsani molondola mizere ya font, pewani bwino mawu amtundu wamtundu ndi kutayika kwa sitiroko, makamaka vuto la mzere wodula.
Kukonza zithunzi zachilengedwe zachikhalidwe
NMSC Natural image processing
Zithunzi zachilengedwe zokonzedwa ndi ukadaulo wanzeru wazithunzi wa Nova NSMC:
chithunzi kapangidwe zambiri zowonetsera ndi wathunthu, mogwira kuchepetsa m'mphepete yokhotakhota maganizo, kusintha, yosalala, zotsatira zabwino.
Ulalo wathunthu 4K@60Hz ukuwonetsa kupanikizana kosalala
Mlingo wotsitsimula wamakanema wachikhalidwe ukhoza kupanga 30Hz, ndikugawidwa pogwiritsa ntchito ukadaulo wapamwamba kwambiri wa HFR (high-frame rate), kutsitsimuka kwamavidiyo mpaka 60Hz, komanso kuchokera pazosonkhanitsira, kutulutsa mawu, kuthandizira ulalo wonse 4K@60Hz, zina. zochitika zotsitsimula zingafikire 120Hz, otsika ngati 60ms kuchedwa, kuthetsa kukokera, kuchedwa, etc.60FPS
Net Sync + Nova Gwirizanitsani nanosecond level Sync
Kutengera Net maukonde kalunzanitsidwe protocol ndi kuphatikiza wapadera Nova kulunzanitsa hardware kalunzanitsidwe luso la Nova, ndi Tianquan anagawira dongosolo amazindikira kalunzanitsidwe wolondola wa dongosolo linanena bungwe wotchi, ndipo akhoza kukhalabe bwino kalunzanitsidwe boma kwa nthawi yaitali, ngakhale kufananizidwa ndi kalunzanitsidwe zipangizo centralized.Kulumikizana kwenikweni kwa nanosecond komwe kumatha kupirira mayeso awiri amaso ndi kamera
NMSC Natural image processing
Kuwonjezera paChiwonetsero cha LED, Tianquan imathandiziranso kuwonetsera, LCD ndi ma TV ena owonetsera.Ndikuthandizira kusamvana kokhazikika (m'lifupi mwake, kukwezeka kwa 819 2), kuti mukwaniritse zofunikira za mawonekedwe amtundu wamtundu wapamwamba kwambiri.Kuphatikiza apo, kuphatikizika kwa synchronous kumatha kupezedwanso m'mawonekedwe angapo okhala ndi m'lifupi mwake ndi kutalika kwake, zomwe zimathetsa vuto lomwe machitidwe ena angapo sangathe kusinthira makonda, zomwe zimapangitsa kuti pakhale kusachita bwino.
NMSC Natural image processing
Pamalo olamulira, malo opangira data ndi machitidwe ena ogawidwa akugwiritsidwa ntchito kwambiri masiku ano, kufunikira kosiyanasiyana kowonetsera, makina ogawa mphamvu a nova amatha kufanana bwino.Chiwonetsero cha LEDkusinthasintha, kukhazikika, kugwira ntchito kosavuta, ndi zina zambiri zofunikira, ndikuwonetsetsa kuti chiwonetsero chazithunzi chapamwamba, ndichoyenera kwambiri pazofunikira zazikulu zamawu ndi makanema, zomwe zimamvetsetsa kwambiri mayankho omwe amagawidwa ndi LED.
