Popis: This study presents a model of a color photograph as a transparent medium with particles of colored pigment embedded in it, with the characteristics of the pigment determining the hue of the picture, and the pigment concentration determining the purity of the color. On the basis of this proposed model, the study undertakes a theoretical examination of an automated method for determining the parameters of a color photograph (the hue and purity) based on scanning the picture with white light and analyzing the output signals of two photodetectors placed behind the photograph in question. Analytical formulae are derived which can be used to measure the color characteristics of a color photograph using the output signals of the photodetectors which, in turn, allows these measurements to be made automatically with simple equipment.
