Abstract

Una cámara de video para simulacion de tiempo real da la apariencia visual de una película cinematográfica que se ha transferido o convertido en una señal del video que comprende un circuito de acondicionamiento de entrada de señal analogica (402), un convertidor analogico a digital (403), un circuito de sincronzacion y control (404), un circuito de multiplexor de direccion y control de memoria (405), una sumadora digital (406), y un convertidor (407) de digital a analogico. Un método para crear el aspecto de difundir una película cinematográfica que comprende los pasos de aumentar el régimen de exploracion de los sensores de imagen a las imágenes de video no entrelazadas de salida, convertir las imágenes de video desde la forma analogica digital, escribir las imágenes en la memoria, añadir una cantidad ajustable selectiva de artefactos electronicos bidireccionales para simular el grano de la película, leer las imágenes de video desde la memoria hacia un bus de dato de salida de video a regímenes predeterminados y convertir las imágenes de video de la forma digital a analogica para registrar o difundir.
