Conventional and multi-spectral digital imaging capture devices can be used for colorimetric measurements. However, a preliminary study of their repeatability and reproducibility is very advisable if they want to be used for this purpose. In this work, a methodology to study the repeatability and reproducibility of such systems is proposed and two digital imaging capture devices working as spectroradiometers with three and seven filters, respectively, are analyzed with respect to a reference tele-spectra-colorimeter. The results of the statistical test show that both have good levels of repeatability, although not the same conclusion is reached regarding the reproducibility, due to some systematic errors.
