Abstract

Dans un appareil de codage de configuration, un dessin de caractère 20 est analysé par un analyseur à spot mobile 24, un transducteur 28 fournissant des signaux à un numériseur 30. Les signaux numérisés sont communiqués à une unité de traitement 32 dans laquelle est produite une représentation réduite se présentant sous la forme d'un contour du caractère analysé. Cette représentation réduite est soumise à un nouveau traitement pour fournir des représentations en binaire de différentes caractéristiques du dessin réduit, à savoir une représentation par segments de vecteurs directionnels et une représentation par bits dans une région rectangulaire contenant le caractère réduit. L'unité de traitement 32 sélectionne la représentation ayant le nombre de bits le plus petit de l'enregistrer dans une unité d'enregistrement 34.
