COMPARISON OF COLOUR REPRODUCTION BY PENTAX K10D DIGITAL CAMERA EMPLOYING POLYNOMIAL MODELS AND ICC BASED COLOUR MANAGEMENT TOOLS

Abstract

This paper deals with the characterization of a Pentax K 10 digital camera in order to be used in colorimetric measurements in a custom built setup employing a LED light source. The experiment focuses on colour characterization using several polynomial transformation models in comparison to ICC based colour characterisation. Altogether 5 polynomial models are applied and evaluated by capturing set of uniform colour patches. Preliminary results indicate, that the complexity of the model does not markedly improve the prediction of CIELAB values.
