Abstract

Se describe un dispositivo de imagen portátil que tiene un receptor de datos que está configurado para recibir datos de imagen codificados de referencia. Los datos incluyen valores de código de referencia que son codificados por un sistema de codificación externo. Los valores de código de referencia representan niveles de gris de referencia que son seleccionados utilizando una función de pantalla de escala de gris de referencia que está basada en la no linealidad perceptual de la visión humana adaptada a diferentes niveles de luz a frecuencias espaciales. El dispositivo de imagen también tiene un convertidor de datos que está configurado para acceder a un mapeo de códigos entre los valores de código de referencia y los valores de código dispositivo-específicos del dispositivo de imagen. Los valores de código dispositivo-específicos están configurados para producir niveles de gris que son específicos al dispositivo de imagen. En base al mapeo de códigos, el convertidor de datos está? configurado para transcodificar los datos de imagen codificados de referencia a datos de imagen dispositivo-específicos, que son codificados con los valores de código dispositivos específicos.
