The akasiyana RGB ruvara?

Nokufamba kwenguva, vanenge vose vakasangana avhareji kombiyuta User panodikanwa kunzwisisa chii ruvara womuenzaniso. ruzivo Izvi zvakare kubatsira kuwedzera horizons.

Saka, pasi ruvara womuenzaniso unonyanyozivikanwa kunzwisiswa husingaoneki chinhu chakadai, umo mumwe ruvara inomiririrwa yakatarwa nhamba. Anoita muenzaniso mhando iyi, Chokwadi, ine maitiro ayo uye utera. Color womuenzaniso runowanzotaurwa nezvarwo mutauro. Somuenzaniso, shoko 'tafura "zvakanyorwa mumitauro yose, uye sezvine zvakasiyana, asi kupindirana kwemuvanzrira wezvirevo nemabviro mutoro oga.

Zvinofanira kucherechedzwa kuti nhasi pane zvakasiyana-siyana ruvara yokutevedzera, asi munyaya ino tichakurukura chete RGB ruvara.

Muna 1861, Maxwell akaita inonakidza kupfimbwa kushandisa yose nzira kuti pave kwakajairika ruvara mufananidzo, izvo akazova shirokoizvesten se "chirungiso Fusion mavara." Warinozokwidzwa kureva kwakajairika Fusion mavara pasi chirungiso ruvara hurongwa nokuwedzera mumwe nomumwe mutema. The chirungiso gadziriro iri conditionally rakakamurwa perceptual uye Hardware-kuzvimiririra.

Nechekare muna 1931 ari RGB ruvara hurongwa kwave vakabudirira kwezvipimo. pamusoro mishumo reInternational Commission atora ruvara nzvimbo "CIE 1931 xyz", izvo vaiona mujinga kusvikira nhasi.

Chokutanga, tinoona kuti mavara ari RGB womuenzaniso ndechimwe zvikuru nevanhu panguva iyoyo. In muenzaniso uyu, ari RGB mavara inoonekwa kubudikidza prism wose mavara matatu: tsvuku (Red), zvitema (Blue) uye girini (Green). Zvisinei, pane mhando mbiri akasiyana muenzaniso uyu: masere ikakuruma kwachakanga mavara anotsanangurwa nenhamba kubvira 0 kusvika 256, uye shestnadtsatibitnaya apo RGB ruvara wakaiswa chero nhamba, asi kubva 0 kusvika zvi-.

Musiyano mukuru Data mienzaniso iri kuti mune yaimbova zvazvingava, nokuti nechimwe (chikuru) ruvara zvakasiyana nevamwe ashandisa yoga scale, uye yechipiri shanduro - akasuma zvakananga Hue.

RGB ruvara womuenzaniso chinhu ndechokuti pane ruvara itsva inotengwa nokuwedzera noruvara kare kuwanikwa mavara chikuru kureva, pane sequential yavo "nokusanganisa '.

Zvakakosha kuziva kuti muenzaniso uyu rinowanzoshandiswa kusanganiswa chimiro, asi kwete zvinhu. Uyezve, kuona kutsvaka kushandisa dzakasiyana ruvara yokutevedzera. The ndechokuti kutarisana RGB ruvara womuenzaniso chinhu kuutio duku kukura matatu, izvo zvisiri nyore zvakakwana kushandisa kubasa Somuenzaniso, imwe programmer kana wakachenjera.

Zvechokwadi, muna wokuenzanisira ichi, RGB ane zvainovhiringidzawo ayo. Chinonyanya kukosha - the kutsamira of kuitika Hardware inodzidzisa. Chinhu ndechokuti chete mufananidzo pamusoro monitors siyana anogona kutarira zvakasiyana (zvakasiyana unhu). Mumwe tarisisa inoshandisa vanonzi phosphor - ndiwo zvinhu chaiyo iyo vatendeuki kuti woga simba senguva dzose chiedza anobuda, saka, kuti kunaka pfuma uye achaita kuvimba dzakwidzwa kuratidzwa mufananidzo.
