RGB yog hom peb lub ntsiab xim ntawm lub teeb xim. Peb lub ntsiab xim yog liab, ntsuab, thiab xiav. Raws li peb cov xim thawj, cov xim ntxiv tuaj yeem xa ncaj qha mus rau qhov muag liab qab, xws li los ntawm kev tshuaj ntsuam. Tus nqi yog R: 0--255 G, 0--255 B, 0--255. Qhov loj dua tus nqi RGB, qhov ci dua. Yog li ntawd, thaum tus nqi RGB yog tag nrho 255, nws yog dawb. Ntawm qhov tsis sib xws, thaum tag nrho RGB yog xoom, nws yog xim dub. Yog li ntawd, RGB interface yog qhov tseeb video interface nrog peb lub ntsiab xim nkag.
RGB xim hom tuaj yeem hu ua liab, ntsuab thiab xiav, tab sis kev lag luam hu ua RGB xim hom. RGB xim yog xim qauv hauv kev lag luam. Cov kev hloov ntawm peb cov xim raws thiab lawv cov superposition kom tau txais ntau yam xim. RGB sawv cev rau cov xim ntawm peb txoj kab liab, ntsuab, thiab xiav. Cov qauv no suav nrog yuav luag txhua yam uas tib neeg lub zeem muag pom tau. Xim yog ib qho ntawm cov xim siv ntau tshaj plaws. Yog li RGB interface yog video interface nrog peb lub ntsiab xim input.
RGB yog xim sib txawv cov tswv yim thiab siv rau cov duab kos duab. Nws tsis yog daim npav kev tshaj lij kom pom qhov txawv.
RGB: Tus txheej txheem ntawm kev encoding xim yog sib sau ua ke hu ua" xim qhov chaw" los yog" xim gamut". Hauv cov ntsiab lus yooj yim tshaj plaws, ib qho
Lub" xim qhov chaw" ntawm ib qho xim tuaj yeem txhais tau tias yog tus lej ruaj khov lossis hloov pauv. RGB (liab, ntsuab, xiav) tsuas yog ib qho ntawm ntau qhov chaw xim. Nrog rau txoj kev coding no, txhua xim tuaj yeem sawv cev los ntawm peb qhov sib txawv - qhov kev siv ntawm liab, ntsuab, thiab xiav. Thaum sau thiab tso saib cov duab xim, RGB yog qhov kev daws teeb meem tshaj plaws.
Cov muaj pes tsawg leeg ntawm VGA teeb liab tau muab faib ua tsib hom: RGBHV, uas yog peb lub ntsiab xim liab, ntsuab thiab xiav, thiab kab rov tav thiab ntsug synchronization teeb liab. Qhov kev sib kis ntawm VGA yog luv heev. Hauv cov haujlwm tiag tiag, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kis tus kab mob Txoj kev sib kis no hu ua RGB kis tau tus mob. Hom teeb liab no tseem hu ua RGB teeb liab.
Hauv lwm lo lus, tsis muaj qhov sib txawv ntawm RGB thiab VGA.
