Abstract

METODO Y APARATO PARA COMPARAR UN ELEMENTO DE IMAGEN SELECCIONADO CON UN ELEMENTO DE IMAGEN PATRON. CONSISTE EN COMPROBAR EL VALOR DE BRILLO DEL ELEMENTO DE IMAGEN SELECCIONADO CON UN INTERVALO PREDETERMINADO DE VALORES DE BRILLO COMUNES A UNA MATRIZ RESPECTIVA DE ELEMENTOS DE IMAGEN DEFINIDOS EN LA VELOCIDAD DEL ELEMENTO DE IMAGEN PATRON. EL APARATO COMPRENDE UNA BANDA CONTINUA (1) SOBRE LA QUE ES IMPRESA UNA MULTIPLICIDAD DE DOCUMENTOS, CUYA BANDA SE HACE PASAR A GRAN VELOCIDAD, ALREDEDOR DE UN RODILLO (3) Y ES EXPLORADA A LO LARGO DE UNA ZONA TRANSVERSAL (4) POR MEDIO DE UNA CAMARA (5) DE EXPLORACION DE LINEA; Y UN CODIFICADOR DE EJE (6) QUE SUMINISTRA INFORMACION A UNA UNIDAD DE CONTROL (7). TIENE UTILIDAD PARA LA INSPECCION DE DOCUMENTOS, TALES COMO BILLETES DE BANCO.
