Abstract

Un agencement est destiné à être utilisé avec un dispositif de balayage de documents pour éliminer le chevauchement des images dans un système multicaméra. Le degré de chevauchement est déterminé en utilisant les données obtenues en balayant un substrat ayant une ligne inclinée (91). Des moyens (87) sont prévus pour supprimer toute double image.
