1. Sumo
Panguva pfupi yadarika, makambani akasiyana anotsanangura ruvara rwejut zviyero zvakasiyana nekuda kwekuratidzira kwavo, senge ntsc, srgb, Adobe RGB, DCI-p3, uye BT.2020. Uku kupokana kunoita kuti zviome zvakananga kuenzanisa nedata yejamu kumakambani akasiyana-siyana, uye dzimwe nguva ruvara rwejari runoratidzika kunge rwakawedzera kupfuura rimwe chete ne72% gamut, zvichikonzera nyonganiso yakakosha pakati pevateereri. Nekufambira mberi kwehunyanzvi, more Quantum dot (QD) TV uye yakadarika tvs nemabhonzo akakura ari kupinda mumusika. Vanogona kuratidza mavara akajeka akajeka. Nekudaro, ini ndoda kupa pfupiso yakazara yerudzi rwemavara muindasitiri yekuratidzira, ndichitarisira kubatsira indasitiri nyanzvi.
2. Pfungwa uye kuverenga kwemavara gamut
Kutanga, ngatisvike pfungwa yerudzi rwemavara. Mune indasitiri yekuratidzira, ruvara gamut inoreva huwandu hwemavara ayo chishandiso chinogona kuratidza. Iyo yakakura iyo color gamut, yakapamhidzirwa mhando yemhando iyo chishandiso chinogona kuratidza, uye zvakanyanya kugona ndezvekuratidzira zvakanyatsojeka mavara (mavara akachena). Kazhinji, iyo NTSC color Gapt yeTV maitiro ari kutenderera 68% kusvika 72%. TV ine NTSC ruvara Gamut yakakura kupfuura 92% inoonekwa seyakakwira ruvara rweGamu
Kune ziso remunhu, ruvara rwekuona ruzha runonyatsoitika, uye hazvigoneke kudzora mavara nemavara eziso chete. Muchigadzirwa chekuvandudza, dhizaini, uye kugadzira, ruvara runofanira kuiswa kuti uwane chokwadi uye kuenderana mukubereka kwemavara. Munyika chairo, iwo mavara ezvirevo zvinoonekwa anoumba ruvara rukuru rwejut nzvimbo, rine ese mavara anoonekwa neziso remunhu. Kuti uone kuongorora pfungwa yerudzi rwejari gamut, komisheni yepasi rose pane kuvhenekerwa (Cie) yakatanga cie-xy chromaticity diagram. Iyo Chromaticity inoratidzirana mwero weCie yehuwandu hwekutarisirwa kwemavara, zvichireva chero ruvara mune zvakasikwa zvinogona kumiririrwa sepfungwa (x, y) pane chromaticity diagram.
Dhizaini iri pazasi inoratidza iyo cie chrromaticity dhizaini, uko ese mavara mune zvakasikwa zviri mukati memukati memabhiza-yakavezwa nzvimbo. Iyo nzvimbo yakatenderedza mukati medhirivheri inomiririra ruvara rwejut. Vertshi edanho rechitatu ndiwo mavara ekutanga (RGB) yeChiratidzo Chishandiso, uye mavara anogona kuumbwa neaya matatu matatu matatu ekutanga mavara ari mukati mekona. Sezviri pachena, nekuda kwemisiyano muzvikamu zvekutanga zvemavara ezvishandiso zvekuratidzira zvakasiyana, chinzvimbo cheTriangle chinosiyana, zvichikonzera mumabhonzo akasiyana emavara. Iyo yakakura iyo treangle, yakakura iyo color gamut. Iyo formula yekuverenga iyo color Gamut ndeye:
Gamut = seAlcd × 100%
Iko ALCD inomiririra iyo nzvimbo yekona yakaumbwa nemavara ekutanga eLCD kuratidza kuyerwa, uye sekumiririra nzvimbo yeyakajairwa katatu yemavara ekutanga emavara. Saka, ruvara rwejari chikamu chikamu chevaridzi venzvimbo yekuratidzira kwemavara mutemberi garanger treangle, nemusiyano unonyanya kusimuka kubva kune yakatsanangurwa ruvara ruvara rwekuronga uye nzvimbo yemavara yakashandiswa. Iyo yekutanga color nzvimbo parizvino iri kushandiswa ndeye Cie 1931 xy chromaticity nzvimbo uye cie 1976 u'v 'color nzvimbo. Ruvara rwejuru rwakaverengerwa munzvimbo idzi mbiri dzinosiyana zvishoma, asi musiyano uri mudiki, saka sumo inotevera uye mhedziso dzakavakirwa pane cie 1931 xy chromaticity nzvimbo.
Pointer's Gamt inomiririra huwandu hwemhando chaiyo yemavara anoonekwa neziso remunhu. Chiitiko ichi chakagadziriswa zvichibva pakutsvagisa naMichael R. Pointer (1980) uye vanokomberedza kuunganidzwa kwemavara echokwadi (zvisingaonekwe) mune zvakasikwa. Sezvinoratidzwa mudhirowa, inoumba gamutre rearregular. Kana ruvara rwegirini ratidziro racho rinogona kuzadzisa zvizere pointer's Gamut
Yakasiyana-siyana ruvara gamut zviyero
NTSC Standard
Iyo NTSC color Gapt chiyero ndechimwe chezvekutanga uye zvakanyanya kushandiswa zvakanyanya zviyero muindasitiri yekuratidzira. Kana chigadzirwa chisingataure kuti ndeupi ruvara rwejut chiyero chinotevera, inowanzofungidzirwa kushandisa iyo NTSC chiyero. NTSC inomirira iyo National Terevhizheni Nharaunda Dare, iyo yakatanga iyi color gamut standard muna 1953
Iyo NTSC color Gapt yakawanda yakafara kupfuura iyo srgb ruvara gamut. Iyo yekushandura formula pakati payo iri "100% srgb = 72% NTSC," zvinoreva kuti nzvimbo dzegore dze100 Iyo yekushandura formula pakati ntsc uye adobe rg iri "100% Adobe rgb = 95% NTSC." Pakati pevatatu, iyo NTSC Colour Gamut ndeye yakakura, ichiteverwa naAdobe RGB, uyezve SRGB.
srgb / rec.709 ruvara gamut standard
SRGB (yakajairika tsvuku yakasvibira yebhuruu) Rwiyo rwemitauro yemutauro yakagadzirwa neMicrosoft uye hp muna1996 yekupa nzira yekutsanangura, ichibvumira kuwirirana nemirimo mimiriro pane kuratidzwa, maprinta, uye zvidhori. Mazhinji midziyo yedhijitari yekuwana mari inotsigira iyo srgb mwero, akadai se makamera emadhijitari, makandirani, zvigunwe, uye monitors. Pamusoro pezvo, zvinenge zvese zvekudhinda uye zvishandiso zvekutsigira zvinotsigira srgb standard. Iyo recc.709 ruvara gamut chiyero chakafanana neSRGB uye inogona kufungwa yakaenzana. Iyo yakagadziridzwa re2020 Standard ine yakafara ruvara rweGamut, iyo ichakurukurwa gare gare. Iyo yekutanga mavara inoronga yeiyo srgb yakajairwa seinotevera:
SRGB ndiyo mhedziso yemavara ekutonga kwemavara, sezvo inogona kuve yatove yakagadziriswa kubva pakutora mifananidzo uye kuongorora kuratidza uye kudhinda. Nekudaro, nekuda kwezvisingakwanisi pane iyo nguva iyo yatsanangurwa, iyo srgb color gamter chiyero chidiki chidiki, chifukidzo chinenge makumi manomwe neshanu muzana yeNTSC ruvara rweNTSC. Mazuva ano, mizhinji tvs inodarika 100% srgb ruvara gamut.
Adobe RGB ruvara rwejit standard
Adobe RGB ndiyo nyanzvi yemavara gamut yakagadzirwa nekufambira mberi kwehunyanzvi hwekutora kanulogy. Iyo ine nzvimbo yakafara yemavara kupfuura srgb uye yakakurudzirwa naAdobe muna1998. Inosanganisira iyo CMYK ruvara Gaput, iyo isiri iripo muSRGB, ichipa mapfumi emakrakati emavara. Kune nyanzvi mukudhinda, kutora mifananidzo, uye dhizaini dzinoda kunyatsogadziriswa kwemavara mavara, kuratidzira izvo zvinoshandisa iyo Adobe RGB ruvara rweGafu zvakanyanyisa. CMYK inzvimbo yemuvara yakavakirwa pamhepo inosanganisa, inowanzo shandiswa muindasitiri yekudhinda uye kashoma muindasitiri yekuratidzira.
DCI-P3 Ruvara Gapt Standard
Iyo DCA-P3 Ruvara rweGapt Standard neDhijitari Cinema Zvinotara Zvinotaraira Iyo DCI-P3 Standard yakatanga kugadzirwa kune cinema Provesors. Iyo yekutanga color inoronga yeiyo DC-P3 mwero eizvi zvinotevera:
Iyo DCI-P3 Standard inogovera iyo yakafanana bhuruu yekutanga kuronga neSRGB uye Adobe RGB. Yayo tsvuku yekutanga kuronga ndeye ye615nm monochromatic laser, iyo yakajeka kupfuura iyo NTSC tsvuku yekutanga. Iyo yakasvibira yekutanga yeDC-P3 iri zvishoma yero yero ichienzaniswa neAdobe RGB / NTSC, asi zvakajeka. Iyo DCI-P3 Yekutanga Ruvara Gonut Area ndeye 90% yeiyo NTSC chiyero.
Rec.2020 / BT.2020 Ruvara Gapt Standard
Rec.2020 IS A Ultra Yakakwira Tsanangudzo Terevhizheni (UHD-TV) chiyero chinosanganisira ruvara gamut rondedzero. Nekufambisira mberi kwehunyanzvi, terevhizheni resolution uye colevhizheni gamut ramba uchivandudza, kuita iyo yechinyakare yekuvandudza mwero isingakwanisi. Rec.2020, yakakurudzirwa neInternational Telecommunication Union (ITU) muna 2012, ine ruvara rweGamut nzvimbo inenge kaviri iyo yeCoc.709. Iyo yekutanga color inoronga yeRec.2020 ndeyekutevera:
Iyo Rec.20 Ingangoita anenge 0.02% yeiyo DC-P3 uye NTSC 1953 Ruvara Gamuts Kunze kweRec.2020 Ruvara Gapt, izvo zvisina basa. Rec.2020 inovhara 99.9% yePointer's Gamut, ichiita kuti iyo ruvara rukuru rweGamut pakati pevakakurukurwa. Nekufambira mberi kwehunyanzvi uye kugoverwa kwakapararira kweUHD TV, iyo Refordso2020 Standard ichawedzera kuwedzera.
Mhedziso
Chinyorwa ichi chinotanga kuburitsa tsananguro uye nzira yekuverenga yerudzi rweGamut, ipapo yakatsanangurwa iyo yakajairwa ruvara mutambo weGamut muindasitiri yekuratidzira uye zvikamufananidza. Kubva pane yekuona kwenzvimbo, hukama hwehukuru hweiyi ruvara rwejut zviyero zvinotevera: Rec.2020> NTSC> NSEB> DC3> Rec.709 / srgb. Paunenge uchienzanisa nemavara emabhomba ezviratidziro zvakasiyana, zvakakosha kuti ushandise iyo yakafanana mwero uye nzvimbo yemuvara kuti udzivise pfungwa dzinojekesa nhamba. Ndinovimba chinyorwa ichi chinobatsira kune nyanzvi dziri muindasitiri yekuratidzira. Kuti uwane rumwe ruzivo nezve Professional LED ratiridzwa, ndapotakusangana neRTLEDnyanzvi timu.
