Title (EN) FRACTIONAL DOWN-SAMPLING IN IMAGING BARCODE SCANNERS
(FR) SOUS-ÉCHANTILLONNAGE FRACTIONNAIRE DANS DES LECTEURS DE CODE À BARRES PAR IMAGERIE
Abstract:
(EN) A method of improving the performance of an imaging reader includes (1) illuminating a symbol by projecting illuminating light on the symbol from the imaging reader, (2) capturing return light form the symbol as pixel data over a two-dimensional field of view of a solid-state imager having a matrix of image sensors, (3) reducing the number of pixels to generate reduced pixel data, (4) transmitting the reduced pixel data to a decoding circuit.
(FR) L'invention porte sur un procédé d'amélioration de la performance d'un lecteur d'imagerie, lequel procédé comprend (1) l'éclairage d'un symbole par projection de lumière l'éclairage sur le symbole à partir d'un lecteur d'imagerie, (2) la capture de lumière de retour du symbole en tant que données de pixel sur un champ de vue bidimensionnel d'un imageur à semi-conducteurs ayant une matrice de détecteurs d'image, (3) la réduction du nombre de pixels pour générer des données de pixel réduites, (4) la transmission des données de pixels réduites à un circuit de décodage.
