Ziva iyo RGB mwenje weiyoSkin Analyzer

RGB yakagadzirwa kubva pamusimboti weruvara luminescence. Mukutaura kwe layman, nzira yayo yekusanganisa mavara yakafanana nemwenje tsvuku, yegirinhi, uye yebhuruu. Kana mwenje yavo ichipindirana, mavara akasanganiswa, asi kupenya kwakaenzana neKuwanda kwekupenya kwezviviri, zvakanyanya kusanganiswa kunowedzera kupenya, ndiko kuti, kuwedzera kusanganisa.

Kune iyo yepamusoro yemwenje tsvuku, yegirinhi uye yebhuruu, iyo inopenya yepamusoro nzvimbo yepakati mavara matatu ichena, uye hunhu hwekuwedzera musanganiswa: iyo yakanyanya superposition, inopenya.

Imwe neimwe yenzira nhatu dzemavara, tsvuku, yegirini, uye yebhuruu, yakakamurwa kuita 256 mazinga ekupenya. Pa0, "chiedza" ndicho chisina simba - chinodzimwa, uye pa255, "chiedza" ndicho chinonyanya kujeka. Kana iwo matatu-mavara egreyscale maitiro akafanana, grey tones ane greycal value dzakasiyana anogadzirwa, kureva kuti, kana matatu-mavara greyscale ari ese 0, ndiyo yakasviba tema toni; kana matatu-ruvara greyscale ari 255, ndiyo inopenya chena toni .

RGB mavara anonzi anowedzera mavara nekuti iwe unogadzira chena nekuwedzera R, G, uye B pamwe chete (kureva kuti, mwenje wese unoratidzwa kumashure kuziso). Mavara ekuwedzera anoshandiswa mukuvheneka, terevhizheni uye vatariri vekombuta. Semuenzaniso, zviratidziro zvinoburitsa ruvara nekuburitsa mwenje kubva kune tsvuku, girini, uye yebhuruu phosphors. Iyo yakawanda yakawanda yeinooneka spectrum inogona kumiririrwa semusanganiswa wekutsvuka, girini, uye bhuruu (RGB) mwenje muzvikamu zvakasiyana uye kusimba. Kana mavara aya akapindirana, cyan, magenta, uye yero zvinogadzirwa.

Mwenje yeRGB inoumbwa nemavara matatu ekutanga akasanganiswa kugadzira mufananidzo. Mukuwedzera, kunewo ma LED ebhuruu ane yellow phosphors, uye ultraviolet LEDs ane RGB phosphors. Kazhinji kutaura, vese vari vaviri vane misimboti yavo yekufungidzira.

Ose machena mwenje LED uye RGB LED vane chinangwa chimwe, uye vese vanotarisira kuwana mhedzisiro yechiedza chena, asi imwe inoratidzwa zvakananga sechiedza chena, uye imwe inoumbwa nekusanganisa tsvuku, girini uye bhuruu.
