Abstract

METODOS Y APARATOS GENERAN, Y USAN EN LA IMPRESION, UNA MATRIZ DE VIBRACION (11) QUE INCORPORA UNA FUNCION DE RESPUESTA INTENSA (Y,11-12; 15-16) QUE PERMITE UNA CURVA DE RESPUESTA GENERALMENTE EN FORMA DE S (11-12). LA IMPRESION CON ESTA CELULA DE VIBRACION PREGENERADA ES JUSTO, TAN RAPIDA COMO CON UNA CELULA CONVENCIONAL PERO EL COLOR IMPRESO TIENE UNA INTENSIDAD LIGERAMENTE EXAGERADA, MAS AGRADABLE PARA LA MAYOR PARTE DE LOS USUARIOS QUE EL COLOR REPRODUCIDO CON MAS EXACTITUD. EL COLOR IMPRESO CON ESTA CURVA (11-12) SOLO, SIN EMBARGO, SE ENCUENTRA INSATISFACTORIAMENTE OSCURO; LA INVENCION TAMBIEN ENCIERRA INCLUIR EN LA RESPUESTA TOTAL (15-16) OTRA FUNCION (Z[X], FIGURA 5) PARA MITIGAR LOS COLORES PARTICULARMENTE EN EL EXTREMO INFERIOR DEL RANGO DE BRILLOS. NOSOTROS DEFINIMOS AMBAS FUNCIONES COMO ASI LLAMADAS "FUNCIONES GAMMA" PERO CON DIFERENTES ARGUMENTOS (X,Y) Y EXPONENTES ({GA}{SUB,1} {GA}{SUB,2}) Y SE CONSTRUYE LA CURVA EN FORMA DE S COMO DOS SECCIONES SEPARADAS (11, Y FIGURA.4B; VS.12, Y EL EXTREMO DERECHO DE FIGURA.4C) MEZCLADAS UN PUNTO CENTRAL (H,M). PREFERIBLEMENTE EL ARGUMENTO DE LA PRIMERA SECCION DE (BRILLO INFERIOR) (11) ES UNA EXPRESION ([X-S]/M) QUE ES PROPORCIONAL A UNA SEÑAL DE COLOR DE ENTRADA (X); LA FUNCION ELEVA ESTE ARGUMENTO A UNA POTENCIA ({GA}{SUB,1}) MAYOR QUE LA UNIDAD (IDEALMENTE 1.6). LA SEGUNDA SECCION (BRILLO SUPERIOR) (12) DE LA PRIMERA FUNCION ES ESENCIALMENTE UNA IMAGEN DE ESPEJO DE LA PRIMERA, DISPERSADAS SOBRE LA PRIMERA HACIA ARRIBA Y DESPUES A LA "DERECHA" (P.EJ., EN AMBAS ETAPAS HACIA UN BRILLO SUPERIOR); Y SE DEFINE POR UNA ECUACION MUY ANALOGA A LA PRIMERA PERO USANDO UN ARGUMENTO DIFERENTE ([H-X]/M) PARA MEDIR LA SEÑAL DEL EXTREMO SUPERIOR (H) DEL RANGO DE ENTRADA, Y SUSTRAER EL VALOR DE LA CURVA DE LA SALIDA MAXIMA F. LA SEGUNDA FUNCION GAMMA TIENE COMO SU ARGUMENTO (Y) EL VALOR DE SALIDA DE LA PRIMERA, Y UN EXPONENTE ({GA}{SUB,2}) INFERIOR A UNO 0.6 OPTIMO.
