During a modification of SaarCor system a method for interpixel interpolation based on the assumption that adjacent pixels traced images have roughly the same color options was proposed. The main idea is: to trace the pixels with a some step, depending on the quality needs. To perform adjustment of an interpolation step a coefficient of color differences is used. This article gives an analysis of the methods for a Color Difference determining. The transformation of the RGB color components to the LAB – model is considered. The tolerances in the color components' differences for RGB-model are calculated. A UML-model of a unit for color differences analyzes is developed. Keywords: color components, color difference, RGB-model, unit, UML-diagram.
