Towards the Design of Low Cost Colorimetric Imaging Device

In this paper we present a preliminary study towards the design of a low cost colorimetric imaging device. We show that an effective color measurement is possible even using consumer camera sensors. We present here the colorimetric accuracy test results obtained with simulated data using the theoretical model of image formation and a camera simulation system. The final paper will also include the colorimetric accuracy test results obtained with real camera sensors. For all the experiments the multispectral response has been obtained by the overlap of colored filters on the existing color filter array pattern. Many consumer devices can benefit from the colorimetric accuracy of such a system, e.g. printers with automatic color management characterization or other consumer devices where an accurate color response is required. © 2011 IEEE.
