cze Závislost bavové paměti na pozorovacích podmínkách V článku je prezentovaný pamäťový experiment, kde sa použilo 5 farieb (červená, zelená, modrá, žltá a farba kože). Farebné políčka boli zobrazené na kalibrovanom LCD monitore. Pri určených podmienkach si pozorovatelia dané farby mali zapamätať. Miešanie farieb prebiehalo pod rovnakými podmienkami ako zapamätávanie, a rovnako aj pod dvoma ďalšími podmienkami. Podmienky sa líšili iba v parametroch pozadia a okolia. Na predpovedanie farbových atribútov pod rôznymi pozorovacími podmienkami bol použitý model farebného vnemu CIECAM02. Najmenší pamäťový posuv farby bol pozorovaný pre atribút tón farby, špeciálne u červenej farby. Výsledky indikujú, že CIECAM02 má určité obmedzenia hlavne pri predpovedaní atribútov chroma a sýtosť, pri podmienkach s čiernym pozadím. Celkovo nebol predpoklad farbových atribútov v pamäťovom experimente dostačujúci barvová paměť, barevný vjem, CIECAM02
eng Colour Memory Match Under Disparate Viewing Conditions A color memory experiment with 5 colors (red, green, blue, yellow, and Caucasian skin color) was carried out. The color patches, shown on an LCD monitor, was memorized under a given viewing condition. The mixing of the memory color was then done first under the same viewing condition, and subsequently under other two altered viewing conditions. The conditions were different in the background and surround parameters. The color appearance model CIECAM02 was then used to predict color attributes under the altered viewing conditions. The lowest color memory shift in hue attribute was found for the red color. CIECAM02 seemed to have some limitation in colorfulness and chroma attribute prediction, for colors viewed on a black background. The result show, that the color attributes prediction in color memory experiment was not successful. color memory, color appearance, CIECAM02
