Abstract

1.- Un método para ajustar la respuesta en la escala de grises de un primer escaner y un segundo escaner de manera que las dos respuestas en la escala de grises concuerden mas exactamente entre si, caracterizado porque comprende los siguientes pasos:proporcionar un primer escaner que tiene una respuesta en la escala de grises al escanear un objeto;proporcionar un segundo escaner que tiene una respuesta en la escala de grises al escanear dicho objeto que es ajustable;medir la respuesta en la escala de grises del primer escaner al escanear el objeto;medir la respuesta en la escala de grises del segundo escaner al escanear el objeto; yajustar la respuesta en la escala de grises del segundo escaner para que concuerde mas exactamente con la respuesta en la escala de grises del primer escaner.2.- El método tal como se reivindica en la reivindicacion 1, caracterizado porque el primer escaner tiene una respuesta en la escala de grises de fabrica que no es ajustable.
