XYZ odkazuje na Barevn\u00fd prostor<\/a> \"CIE XYZ\", kter\u00fd je tak\u00e9 zn\u00e1m\u00fd jako barevn\u00fd prostor CIE 1931 XYZ. CIE je zkratka pro Commission Internationale de l'\u00c9clairage, Mezin\u00e1rodn\u00ed komisi pro osv\u011btlen\u00ed, a XYZ ozna\u010duje matematick\u00e9 sou\u0159adnice barevn\u00e9ho prostoru. Pro jednoho z\u00e1kazn\u00edka tiskneme ter\u010de XYZ-EPS v maxim\u00e1ln\u00edm barevn\u00e9m prostoru na\u0161\u00ed spole\u010dnosti. D\u016fkazy<\/a>yst\u00e9my. Pokud tedy m\u00e1te vyti\u0161t\u011bn\u00e1 data XYZ, nev\u00e1hejte se na n\u00e1s kdykoli obr\u00e1tit.<\/p>\n

Barevn\u00fd prostor CIE XYZ je barevn\u00fd prostor nez\u00e1visl\u00fd na za\u0159\u00edzen\u00ed, kter\u00fd byl vyvinut organizac\u00ed CIE za \u00fa\u010delem modelov\u00e1n\u00ed lidsk\u00e9ho vn\u00edm\u00e1n\u00ed barev. Je zalo\u017een na z\u00e1kladn\u00edch barv\u00e1ch X, Y a Z a slou\u017e\u00ed jako reference pro dal\u0161\u00ed barevn\u00e9 prostory a barevn\u00e9 modely<\/a>. Barevn\u00fd prostor XYZ tvo\u0159\u00ed spojnici mezi fyzik\u00e1ln\u00edmi vlastnostmi sv\u011btla a lidsk\u00fdm vn\u00edm\u00e1n\u00edm barev.<\/p>\n

V barevn\u00e9m prostoru XYZ jsou v\u0161echny barvy reprezentov\u00e1ny jako trojrozm\u011brn\u00e9 sou\u0159adnice, p\u0159i\u010dem\u017e X, Y a Z p\u0159edstavuj\u00ed jas a pod\u00edl p\u0159\u00edslu\u0161n\u00e9 z\u00e1kladn\u00ed barvy. Hodnota Y p\u0159edstavuje jas nebo sv\u00edtivost barvy, zat\u00edmco X a Z jsou barevn\u00e9 sou\u0159adnice, kter\u00e9 ud\u00e1vaj\u00ed spektr\u00e1ln\u00ed slo\u017eku barvy.<\/p>\n

Barevn\u00fd prostor CIE XYZ tvo\u0159\u00ed z\u00e1klad pro dal\u0161\u00ed barevn\u00e9 prostory, jako je barevn\u00fd prostor CIE Lab<\/a> (viz tak\u00e9 voln\u00fd barevn\u00fd CIELAB<\/a> HLC<\/a> atlas barev, p\u0159i\u010dem\u017e HLC p\u0159edstavuje jinou formu barevn\u00e9ho prostoru CIELAB) a RGB<\/a> barevn\u00fd prostor. P\u0159evodem mezi r\u016fzn\u00fdmi barevn\u00fdmi prostory lze barvy zobrazovat a reprodukovat v r\u016fzn\u00fdch syst\u00e9mech.<\/p>","protected":false},"excerpt":{"rendered":"
