Abstract

L’invention porte sur une image (1) incluant un code bidimensionnel à lecture optique (10), comprenant, en des emplacements prédéfinis d’une matrice bidimensionnelle (19), un premier ensemble d’emplacements (14) présentant une luminosité inférieure à un premier seuil prédéfini codant un premier état binaire, un deuxième ensemble d’emplacements (15) présentant une luminosité supérieure à un deuxième seuil prédéfini codant un deuxième état binaire, l’image (1) comporte un premier motif continu (21) ayant une première chromaticité homogène et un deuxième motif continu (32) ayant une deuxième chromaticité homogène, les première et deuxième chromaticités étant différentes, le premier motif continu couvrant plusieurs emplacements du deuxième ensemble, le deuxième motif continu couvrant plusieurs autres emplacements du deuxième ensemble. Figure à publier avec l’abrégé : Fig. 1The invention relates to an image (1) including a two-dimensional optically readable code (10), comprising, at predefined locations of a two-dimensional matrix (19), a first set of locations (14) having a brightness less than a first predefined threshold encoding a first binary state, a second set of locations (15) having a brightness greater than a second predefined threshold encoding a second binary state, the image (1) comprises a first continuous pattern (21) having a first homogeneous chromaticity and a second continuous pattern (32) having a second homogeneous chromaticity, the first and second chromaticities being different, the first continuous pattern covering several locations of the second set, the second continuous pattern covering several other locations of the second set. Figure to be published with the abstract: Fig. 1
