Kusarudza Kuti Zvakanaka Sei LCD Monitor iri kuRointing Color
Ruvara gamut rinoreva mavara akasiyana-siyana emavara anogona kuenzanisirwa nechigadzirwa. Iko kune zvechokwadi mavara maviri emuvara gamuts, kuwedzera uye kusunungura. Kuwedzera kunoreva muto unoitwa nekubatanidza pamwe chiedza chemavara kuti uite ruvara rwekupedzisira. Iyi ndiyo nzira inoshandiswa nemakombiyuta, terevhizheni nedzimwe nhumbi. Inowanzonzi inonzi RGB inobva pachiedza chitsvuku, chine ruvara uye chebhuruu chinoshandiswa kuunza mavara. Kuchengeta ruvara ndiyo inoshandiswa nokubatanidza pamwe madhayi anodzivirira kufungisisa kwechiedza icho zvino chinobudisa ruvara. Iyi ndiyo nzira inoshandiswa pane zvose zvakadhindwa zvakadai semifananidzo, magazini, uye mabhuku. Iyo inowanzonziwo CMYK yakagadzirwa neichan, magenta, yellow uye black pigments inoshandiswa mukudhinda.
Sezvo tichitaura pamusoro peLCD vatariri munyaya ino, tichave tichitarisa RGB ruvara rwemagetsi uye kuti vataridzi vakasiyana vanoverengerwa sei ruvara rwavo. Dambudziko nderokuti kune mavara akasiyana-siyana akasiyana-siyana gamuts kuti chinyorwa chinogona kuverengwa ne.
sRGB, AdobeRGB, NTSC uye CIE 1976
Kuti uenzanise kuti ruvara rukuru runogona kubata sei, rinoshandisa imwe yemhando yakasiyana-siyana yemarutsu inotsanangura imwe ruvara rwemvara. Nyaya yakawanda yeRGB based color gamuts is sRGB. Iyi ndiyo inowanzo ruvara rwemutambo inoshandiswa pamakombiyuta ose, maTV, makamera, video recorders uye mamwe magetsi emagetsi. Iyo ndeye yekare uye yakanyanya kudarika yemuvara gamuts iyo inoshandiswa pakurondedzera kombiyuta uye watengi zvemagetsi.
AdobeRGB yakagadziridzwa neAdobe semuvara wema gamut kuti ipe mararamiro akasiyana-siyana kupfuura sRGB. Vakagadzira izvi kuti ishandiswe nemhando dzakasiyana-siyana dzemapurogiramu dzinosanganisira Photoshop senzira yekupa vatsigiri huwandu hwemavara pavanoshandisa mafirimu nemifananidzo vasati vashandura kuti vaparidze. CMY ine ruvara rwakakura zvikuru rwakatariswa neRGB gamuts, saka iyo yakawanda AdobeRGB gamut inopa shanduro iri nani yevaraidzo kudhinda kupfuura sRGB.
NTSC yakave nzvimbo yevaravara yakagadzirwa nokuda kwemavara emhando inogona kumira kumeso evanhu. Inongovawo mumiriri weavo vanoonekwa mavara ayo vanhu vanogona kuona uye haasi chaizvo iyo yakareba muto gamut inogona. Vakawanda vangafunga kuti izvi zvine chokuita nehuterevhizheni huwandu hunotumidzwa zita, asi hazvisi. Nzvimbo dzakawanda dzezvigadzirwa zvenyika zvekare dzisingakwanisi kusvika pamwero uyu wemuvara mukuratidzira.
Ikupedzisira yemutambo gamuts iyo inogona kutaurwa muLCD kupenya ruvara ruzivo ndiCIE 1976. Mifananidzo yeCIE yakave imwe yenzira dzokutanga dzekutsanangura maitiro emhando chaiyo. Shanduro ye1976 yeiyi inzvimbo yakasiyana-siyana yemuvara inoshandiswa kuratidzira kushanda kweimwe nzvimbo dzemavara. Inowanzosava yakanyanyisa uye semugumisiro ndeyekuti makambani akawanda anofarira kushandisa sezvo inowanzova nenhamba yepamusoro yepamusoro kupfuura yevamwe.
Saka, kuenzanisa maruva akasiyana-siyana gamuts maererano nehuwandu hwehuwandu hwemhando yehupfupi kudarika kusvika kune yakawanda ichange iri: CIE 1976 Maziso anowanzoverengwa pamusana wavo nehuwandu hwemavara kunze kwemuvara wemutambo unogona. Nokudaro, gadziriro inorongwa pa100% NTSC inogona kuratidza mavara ose mukati meNTSC ruvara rwemutambo. Sirivha ine 50% NTSC ikara gamut inogona kungomirira hafu yeaya mavara. Ivhareji yemakombiyuta inotarisa icharatidza zvakapoteredza 70 kusvika ku75% yeNTSC ruvara rwemutambo. Izvi zvakanaka kuvanhu vakawanda sezvavanoshandiswa kumusana wavakaona pamusoro pemakore kubvira pane terevhizheni uye mavhidhiyo. (72% yeNTSC inenge yakaenzana ne100% yemuvara weRRBB gamut.) ICRTs inoshandiswa mumafirimu akawanda ekare mabheji uye mavara ekuvaraidza zvakare akabudiswa zvinenge 70% muvaravara wegutut. Vaya vari kutarisa kushandisa sarudzo kwekushandura kwemaitiro ekufambisa kana basa zvingangove zvichida chimwe chinhu chine ruzivo rwakakura rwemavara. Ikoko ndiko kwakawanda mavara evanhu vatsva kana kuti marefu emakwikwi emakwikwi ari kutamba. Kuti uratidze kuve yakarongerwa sevheti yepamusoro, inowanzodikanwa kutora zvinenge 92% NTSC ruvara rwemutambo. Anonzi LCD monitor's backlight ndiyo chinhu chinokosha mukugadzirisa ruvara rwayo yose gamut. Chiedza chinowanzojairika chinoshandiswa muLCD ndeCCFL (Cold-Cathode Fluorescent Light). Izvi zvinowanzogadzira zvakapoteredza 75% NTSC ikara gamut. Kugadziriswa kweCCFL magetsi kunogona kushandiswa kubudisa inenge 100% NTSC. Nhamba itsva yekugadzirisa LED yakakwanisa kuunza zvakapfuura 100% NTSC ruvara gamuts. Taura izvozvo, maLCD akawanda anoshandisa maitiro ekudhura kwe LED anobudisa huwandu hwemavara emutambo gamut huri pedyo neCCFL chaiyo. Kana muvara weLCD yemuenzaniso chinhu chinokosha chekombiyuta yako, zvakakosha kuziva kuti yakawanda ruvara rungaratidza sei. Zvinyorwa zvitsva zvinongorodza nhamba yemashizha hazviwanzobatsiri uye zvisinganzwisisiki kana zvasvika kune zvavanonyatsoratidza pane izvo zvavanogona kuita. Nokuda kweizvi, vatengi vanofanira kunyatsodzidza kuti checheta yevarai gamut chii. Izvi zvichapa vatengi mumiririri wepamusoro weiyo inotarisa inokwanisa kuburikidza nemuvara. Iva nechokwadi chekuziva kuti chiyero ichi chii uyewo ruvara gamut icho chikamu chakavakirwa. Heino runyararo rutsva rwemajaya akafanana emazinga akasiyana ekuratidzira: Pakupedzisira, mumwe anofanirwa kuyeuka kuti nhamba idzi dzinobva apo chiratidzo chinonyatsogadziriswa. Yakawanda inoratidza apo inotumirwa ichienda kuburikidza nemhando yakawanda yemavara calibration uye ichanyanyisa pane imwe yemamwe nzvimbo. Somugumisiro, ani zvake anoda chikwata chakanakisisa chevara achada kuisa chiratidziro chako nemaprofita akakodzera uye kuchinjwa achishandura chigadziro chekugadzirisa. Chii chinonzi Chimiro Chimiro Gamut chekuratidzira?
