Abstract

LA INVENCION SE REFIERE A UN SISTEMA PARA REALIZAR AUTOMATICAMENTE EL TEST DE CONTRASTE RESOLUBLE MINIMO (MRC) EN UN SENSOR DE IMAGENES (20), TAL COMO UNA CAMARA DE TV, LA CAMARA USA UN PROCESADOR DE SEÑALES DIGITALES (10) PARA CONTROLAR EL TEST, EN DONDE SE USA UNA RESPUESTA DE BORDE CORRESPONDIENTE AL BORDE DE UN BLANCO DE ABERTURA CUADRADO (21) PARA GENERAR UNA FUNCION DE TRANSFERENCIA DE MODULACION (MTF) LA CUAL, EN COMBINACION CON LOS DATOS DE LA SEÑAL Y DEL RUIDO OBTENIDOS UTILIZANDO EL BLANCO DE ABERTURA CUADRADO, PROPORCIONA UNA ENTRADA A LAS ECUACIONES DE PROCESAMIENTO AUTOMATIZADO MRC (AMRC), A PARTIR DE LAS CUALES SE PUEDE CALCULAR UN VALOR PARA UNA SALIDA AMRC. ALTERNATIVAMENTE, UN BLANCO DE RENDIJAS (2A Y 2B) SE PUEDE SUSTITUIR POR LA ABERTURA DEL BLANCO CUADRADO CUANDO ESTA MIDIENDO LA CAMARA MTF.
