Abstract

Un convolucionador de video bidimensional genera imágenes visualmente aceptables en un receptor de television estándar, e incluye primera y segunda etapas sumadoras, y dos demoras del período de tiempo de los pixeles. La primera etapa sumadora recibe simultáneamente datos binarios desde tres pixeles adyacentes en una línea previamente determinada en una primera direccion de una imagen que se va a reproducir en un despliegue visual durante cada período de exploracion de pixeles. La segunda etapa sumadora responde a una señal de salida binaria de la primera etapa sumadora durante un período de tiempo para cada una de tres líneas adyacentes previamente determinadas en una segunda direccion ortogonal de una imagen que se va a reproducir en un despliegue visual. La ponderacion se realiza en las primera y segunda etapas sumadoras mediante la utilizacion de bits de datos binarios para un pixel como se recibieron cuando el peso para ese pixel es en un uno numérico, y cambiando los bits de datos binarios recibidos por un numero previamente determinado de y bits en una primera direccion para proporcionar una funcion de multiplicacion cuando un peso respectivo es mayor que uno y es igual a 2y.
