Abstract

L'INVENTION CONCERNE UN SYSTEME DE TRANSMISSION PAR FAC-SIMILE A RECONNAISSANCE DE CARACTERES. LE SIGNAL EMIS PAR UN DISPOSITIF DE TRANSMISSION PAR FAC-SIMILE UTILISE DU COTE EMETTEUR EST RECU PAR UN DISPOSITIF 4 ANALOGUE DU COTE RECEPTEUR ET EST TRANSFORME EN UNE DONNEE DE FORME DE CARACTERE DE DOCUMENT. CETTE DONNEE EST DELIVREE A UNE SECTION 26 DE RECONNAISSANCE DE CARACTERES OU ELLE EST SOUMISE A UN PROCESSUS DE RECONNAISSANCE DE CARACTERES. UN CARACTERE QUI NE PEUT ETRE RECONNU PAR LA SECTION CONSERVE SON INTEGRITE, TANDIS QUE LE CARACTERE RECONNU EST TRANSFORME EN UN CARACTERE NORMALISE. UN DOCUMENT QUI CONTIENT LE CARACTERE NON RECONNAISSABLE EST IMPRIME EN VUE DE SON IDENTIFICATION.
