Title
(EN) PRODUCING OR CHARACTERISING COLOUR IMAGES AND MEASURING COLOUR
(FR) PRODUCTION ET CARACTERISATION D'IMAGES EN COULEUR ET MESURE DE LA COULEUR
Abstract
(EN)
There is disclosed a method of extracting information from an object or object scene comprising illuminating the object or scene by a plurality of primary colour illuminants and measuring or recording the resulting light from the object or scene.
