Bona ukukhanya kwe-RGB kwe-I-Skin Analyzer
I-RGB yakhelwe kusukela kumgomo we-luminescence yombala. Ngokwabantu abavamile, indlela yayo yokuxuba imibala ifana nezibani ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka. Uma izibani zazo zidlulana, imibala iyaxutshwa, kodwa ukukhanya kuyalingana nesamba sokukhanya kokubili, okuxutshwa kakhulu kuyanda ukukhanya, okungukuthi, ukuxuba okungeziwe.
Ngokuphakama kwezibani ezibomvu, eziluhlaza neziluhlaza okwesibhakabhaka, indawo egqame kakhulu yemibala emithathu emaphakathi imhlophe, kanye nezici zokuhlanganisa okungeziwe: indawo ephezulu kakhulu, ikhanya kakhulu.
Ishaneli ngayinye yemibala emithathu, obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka, ihlukaniswe ngamaleveli angama-256 okukhanya. Ku-0, "ukukhanya" kubuthakathaka kakhulu - kuvaliwe, futhi ku-255, "ukukhanya" kukhanya kakhulu. Uma amanani emibala emithathu empunga efanayo, amathoni ampunga anamanani ahlukene e-grayscale ayakhiqizwa, okungukuthi, lapho umbala ompunga onemibala emithathu yonke ingu-0, iyithoni emnyama kakhulu; lapho umbala ompunga onemibala emithathu ingu-255, iyithoni emhlophe egqame kakhulu.
Imibala ye-RGB ibizwa ngemibala engezayo ngoba udala emhlophe ngokungeza u-R, G, no-B ndawonye (okungukuthi, konke ukukhanya kuboniswa emuva esweni). Imibala engeziwe isetshenziswa ekukhanyeni, kumabona kude nama-computer monitors. Isibonelo, izibonisi zikhiqiza umbala ngokukhipha ukukhanya okuvela ku-phosphor ebomvu, eluhlaza, neluhlaza okwesibhakabhaka. Iningi le-spectrum ebonakalayo lingamelwa njengengxube yokukhanya okubomvu, okuluhlaza okotshani, nokuluhlaza okwesibhakabhaka (RGB) ngezilinganiso nokuqina okuhlukahlukene. Uma le mibala idlulana, i-cyan, i-magenta, nephuzi iyakhiqizwa.
Izibani ze-RGB zenziwe ngemibala emithathu eyinhloko ehlanganiswe ukwenza isithombe. Ngaphezu kwalokho, kukhona nama-LED aluhlaza ane-phosphor ephuzi, nama-ultraviolet LED ane-RGB phosphors. Ngokuvamile, bobabili banezimiso zabo zokucabanga.
Kokubili ukukhanya okumhlophe kwe-LED ne-RGB LED kunomgomo ofanayo, futhi bobabili banethemba lokuzuza umphumela wokukhanya okumhlophe, kodwa eyodwa yethulwa ngokuqondile njengokukhanya okumhlophe, kanti enye yakhiwa ngokuxuba okubomvu, okuluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka.
