Term (SR)kontrast
Definition (SR)a) u smislu percepcije: razlika u izgledu dvaju ili više dijelova polja viđenih istovremeno ili uzastopno NAPOMENA Primjeri tipova kontrasta su kontrast osvijetljenosti, kontrast boja, istovremeni kontrast, uzastopni kontrast itd. b) u fizičkom smislu: količina koja treba da odgovara predviđenom kontrastu osvijetljenosti, obično definisanom jednom od brojnih formula koje uključuju osvijetljenosti razmatranih podražaja NAPOMENA Na primjer: kontrast je dat sa ΔL/L blizu praga osvjetljenja, ili sa L1/L2 za mnogo veće osvjetljenje.
