| Abstract | Boja je psihofizicki doživljaj za koji su potrebne tri komponente, svjetlost, obojeni objekt i vizualni sustav. Boju vidimo kada vidljiva svjetlost odredene valne duljine padne na obojeni objekt prilikom cega dolazi do transmisije,
apsorpcije ili refleksije. Vizualni sustav ima ulogu da svjetlost koja upada u oko preko optickog živca bude prenesena u mozak.
Prilikom definiranja boje, za što jednostavnije razumjevanje, koriste se atributi boje kao što su ton, svjetlina i zasicenje. Kod modela za prikaz boja važno je
razlikovati šest atributa boje, a to su svjetlina, relativna svjetlina, zasicenje, relativno zasicenje, apsolutno zasicenje i ton boje.
Doživljaj boje mijenja se ovisno o uvjetima promatranja. Iz tog razloga koriste se modeli za prikaz boje koji imaju sposobnost predvidanja promjene u boji koja je
nastala zbog promjene u uvjetima promatranja, razini osvjetljenosti ili spoznaji.
Svaki od modela za prikaz boja ima odredene prednosti i mane, te ne postoji
jedinstveni model primjenjiv na sve sustave.
Ti modeli su CIELAB, CIELUV, Huntov model, Nayatani model, RLAB, ZLAB,
LLAB, ATD model, CIECAM97s, CIECAM02.
U eksperimentalnom dijelu rada, pomocu kolorimetra mjerene su boje na cetiri
tableta sa ciljem pronalaska modela (RLAB, ZLAB, CIECAM97s, CIECAM02)
koji bi se mogao primjenjivati na tabletima. |
| Abstract (english) | Color is a psychophysical experience that requires three components, light,
colored object and the visual system. We see color when visible light of a
specific wavelength falls on a colored object, then we have transmission,
absorption or reflection. The visual system has a function to light that falls in to
the eye, through the optic nerve transmit to the brain.
When we define colors, for simpler understanding, we use attributes such as
hue, brightness and colorfulness. For color appearance models is important to
distinguish between the six dimensions of color- brightness, lightness,
saturation, colorfulness, chroma and hue.
Color experience changes depending on the viewing conditions. For this
reason, models are used to display colors that have the ability to predict
changes in color, which is caused by changes in the conditions of observation,
the level of brightness or knowledge.
Each of color appearance models has some advantages and disadvantages,
and there is no single model applicable to all systems. These models are
CIELAB, CIELUV, Hunt model, Nayatani model, RLAB, ZLAB, LLAB, ATD
model, CIECAM97s, CIECAM02.
In the experimental part, using the colorimeter measured the color on the four
tablets with the aim of finding models (RLAB, ZLAB, CIECAM97s, CIECAM02)
that could be applied to the tablets. |
