Abstract

Un sistema y un método para producir y observar, por un observador, imágenes monocromas y a color bidimensionales y tridimensionales para radiodifusion de acuerdo a los formatos NTSC, PAL, SECAM, y otros formatos mundiales de observacion electronica. La invencion comprende un dispositivo de cámara 110, un dispositivo de observacion, un transmisor 15 para transmitir una señal de avance, y al menos un par de espejuelos de observacion 76. El dispositivo de cámara 110 incluye un lente de produccion de imágenes sencillas 18 que tiene una válvula de luz bifurcada de apertura doble 30, y un espacio de imagen sencilla para recibir y superponer una pluralidad de imágenes del ojo izquierdo y una pluralidad de imágenes de ojo derecho a una frecuencia de campo indicada por la señal de avance. El dispositivo de observacion incluye un receptor de television 86. El transmisor 15 puede ser un transmisor de frecuencia de radio, ultrasonica, o infrarroja. El par de espejuelos de observacion 76 incluyen una válvula de luz de observacion izquierda 77 y una válvula de luz de observacion derecha 78. En respuesta a la recepcion de la señal de avance, la válvula de luz de observacion izquierda 77 se abre y se cierra sincronizada con la frecuencia de campo, para observar la pluralidad de imágenes del ojo izquierdo. La válvula de luz de observacion derecha 78, en respuesta a la señal de avance, se abre y cierra sincronizada con la frecuencia de campo, pero alternadamente con la válvula de luz de observacion izquierda 77, para observar la pluralidad de imágenes del ojo derecho. La pluralidad de imágenes del ojo izquierdo y la pluralidad de imágenes del ojo derecho aparece tridimensionales cuando son vistas a través del par de espejuelos de observacion 76, y aparecen bidimensionales al ser vistas sin el par de espejuelos de observacion 76.
