Abstract

LA INVENCION DESCRIBE UN APARATO DE PROCESAMIENTO DE IMAGENES EN COLOR, QUE ANALIZA UNA SATURACION DE UNA IMAGEN DE ENTRADA EN COLOR, Y LLEVA A CABO EL PROCESAMIENTO DE LA IMAGEN DE CONFORMIDAD CON EL RESULTADO DEL ANALISIS DE SATURACION. EL APARATO INCLUYE UN MEDIO DE ENTRADA DE IMAGENES, EN EL QUE UNA PLURALIDAD DE SENSORES DE LINEA, PARA GENERAR SEÑALES DE COMPONENTES DE COLOR EN LA BASE DE CARACTERISTICAS ESPECTRALES DIFERENTES, ESTAN SITUADOS PARALELAMENTE, Y MEDIO PARA ANALIZAR UN AREA ACROMATICA DE SEÑALES DE COMPONENTES DE COLOR, INTRODUCIDAS POR EL MEDIO DE ENTRADA DE IMAGENES, DE CONFORMIDAD CON UN METODO PREVIAMENTE DETERMINADO. ESTA INSTALACION REALIZA EL ANALISIS DE SATURACION CUANDO SE LLEVA A CABO UNA OPERACION DE IMPRESION, UTILIZANDO SOLO NEGRO, PARA UN CARACTER NEGRO, O CUANDO SE ANALIZA SI UN DOCUMENTO ORIGINAL ES UN DOCUMENTO ORIGINAL DE COLOR O MONOCROMO.
