Tagħraf id-dawl RGB tal -Analizzatur tal-Ġilda
RGB huwa ddisinjat mill-prinċipju tal-luminixxenza tal-kulur. F'termini ta 'Layman, il-metodu ta' taħlit ta 'kulur tiegħu huwa bħal dwal ħomor, ħodor u blu. When their lights overlap each other, the colors are mixed, but the brightness is equal to The sum of the brightness of the two, the more mixed the higher the brightness, that is, additive mixing.
Kull wieħed mit-tliet kanali tal-kulur, aħmar, aħdar u blu, huwa maqsum f'256 livelli ta 'luminożità. F'0, id- "dawl" huwa l-iktar dgħajjef - huwa mitfi, u f'255, id- "dawl" huwa l-aktar brillanti. When the three-color grayscale values are the same, gray tones with different grayscale values are generated, that is, when the three-color grayscale is all 0, it is the darkest black tone; Meta l-iskala griża bi tliet kuluri hija 255, huwa l-aktar ton abjad.
RGB colors are called additive colors because you create white by adding R, G, and B together (that is, all the light is reflected back to the eye). Kuluri addittivi jintużaw fid-dawl, it-televiżjoni u l-monitors tal-kompjuter. Pereżempju, il-wirjiet jipproduċu kulur billi jarmu dawl minn fosfri ħomor, ħodor u blu. The vast majority of the visible spectrum can be represented as a mixture of red, green, and blue (RGB) light in varying proportions and intensities. Meta dawn il-kuluri jikkoinċidu, cyan, magenta, u isfar huma prodotti.
Id-dwal RGB huma ffurmati mit-tliet kuluri primarji flimkien biex jiffurmaw immaġni. Barra minn hekk, hemm ukoll LEDs blu bi fosfri sofor, u LED ultravjola bil-fosfri RGB. B'mod ġenerali, it-tnejn li huma għandhom il-prinċipji tal-immaġini tagħhom.
