Abstract
Dispositivo para la exploración óptico-eléctrica de un dibujo, particularmente de un dibujo compuesto de una pluralidad de puntos, cada uno de ellos de un color seleccionado de entre varios colores, y para la transformación de las informaciones obtenidas mediante la exploración de los puntos en señales de color características de los distintos colores, comprendiendo una cabeza exploradora desplazable con respecto a dicho dibujo, provista de varios órganos exploradores óptico-eléctricos, cada uno de ellos sensible a una zona espectral determinada, a continuación de los cuales están dispuestos discriminadores de color para la producción de sendas señales de color, caracterizado porque cada uno de dichos discriminadores de color produce una señal de color únicamente cuando las señales de salida analógicas de todos los órganos exploradores asociados al mismo, o bien las señales derivadas de estas señales de salida, se encuentran dentro de una zona de tolerancia limitada hacia arriba y hacia abajo.
