Qaphela ukukhanya kwe-RGB yeUhlalutyo lolusu

I-RGB yenzelwe ukususela kumgaqo-nkqubo wemibala. Kwimigaqo yendawo yokutsala, indlela yayo yokudibanisa imibala ifana nebomvu, eluhlaza, kunye nezibane eziblowu. Xa izibane zabo zigqobhozane, imibala ixutywe, kodwa ukukhanya kulingana nesixa sokukhanya kwesi sibini, kokungaphezulu kokukhanya, oko kukuthi, ukongeza ukuxuba.

Ukongamela izibane ezibomvu, eziluhlaza kunye nezibane ezibukrakra, indawo eqaqambileyo yendawo ephakathi imibala emincinci imbi, kwaye iimpawu zokuxuba komxube: okuqaqambileyo.

Nanye yezi ndlela zintathu zombala, ibomvu, luhlaza, kunye neblue, zahlulwe zaba ngamanqanaba angama-256 okuqaqamba. E-0, "Ukukhanya" kobuthathaka - icinyiwe, kwaye nge-255, "Ukukhanya" kwelona liqaqambileyo. Xa amaxabiso emibala emithathu emdaka ayalingana, iitoni ezingwevu ezinamaxabiso ahlukeneyo amaGreyscale aveliswa, oko kukuthi, xa i-greycale emithathu yi-0, yithoni emnyama kakhulu; Xa i-raycale yombala emithathu ingama-255, yeyona ithoni emhlophe eqaqambileyo.

Imibala ye-RGB ibizwa ngokuba yimibala yophawu kuba udala mhlophe ngokongeza i-R, G, kunye ne-B kunye (oko kukuthi, konke ukukhanya kubonakaliswa kwamehlo). Imibala eyongeziweyo isetyenziselwa ukukhanyisa, umabonwakude kunye neemowudi zekhompyuter. Umzekelo, imiboniso bonakalisa umbala ngokukhupha ukukhanya ukusuka kwi-bod, eluhlaza, kunye ne-phosphers eluhlaza. Uninzi lwezinto ezibonakalayo ezibonakalayo zinokumelwa njengomxube wobomvu, uluhlaza, kunye noblowu (i-RGB) ukukhanya kwindawo eyahlukeneyo kunye nobuchule. Xa le mibala igqitha, iCyan, iMagenta, kwaye iphuzi.

Izibane ze-RGB zenziwa yimibala emithathu ephambili edityanisiweyo yokwenza umfanekiso. Ukongeza, kukwakhona ii-LED eziblowu ezineephosphors ezityheli, kwaye i-ultraviolet ikhokelwa ngeephosphors zeRGB. Ngokubanzi, bobabini banemigaqo yokucinga.

Zombini ukukhanya okumhlophe kukhokelele kwaye i-RGB yakhokelela kwinjongo enye, kwaye zombini ithemba lokufezekisa ukukhanya okumhlophe, kodwa enye iboniswa ngokuthe ngqo njengoKhanya amhlophe, luhlaza nohlaza okwesibhakabhaka.
