Abstract

Razvoj pametnih mobitela i njihovih kamera omogućio je primjenu digitalne kolorime-trije slike (DIC) u svrhu dobivanja kvantitativne analitičke informacije. U ovom radu provedena su paralelna mjerenja RGB vrijednosti dobivena pomoću softvera pametnog telefona i spektro-fotometrijska mjerenja apsorbancije četiri otopine boja (crvena, plava, zelena, žuta). Ispitana je pouzdanost određivanja koncentracije mobilnim uređajem u odnosu na spektrofotometrijska mjerenja. Temeljem dobivenih rezultata može se zaključiti da kolorimetrija digitalne slike može poslužiti kao jednostavan, brz i ekonomičan alat za dobivanje pouzdanog rezultata.

Abstract (english)

The development of smart cell phones and their cameras enabled the application of dig-ital image colorimetry (DIC) for the purpose of obtaining quantitative analytical information. In this work, parallel measurements of RGB values obtained using smartphone software and spectrophotometric measurements of apsorptivity on four color solutions (red, blue, green, yel-low) were performed. The reliability of concentration determined using a mobile device com-pared to spectrophotometric measurements was tested. Based on the obtained results it can be conclude that digital image colorimetry can serve as a simple, fast and economical tool for obtaining a reliable result.
