Abstract

UN PROCESADOR DE RASTREO PROGRESIVO (30) QUE INCLUYE UN CIRCUITO DE ENTRADA (30A) QUE PRODUCE UNA SEÑAL DE DIFERENCIA DE VIDEO (Y12) QUE REPRESENTA LA DIFERENCIA ENTRE UN PRIMER COMPONENTE DE BAJA FRECUENCIA (Y6) DERIVADO DE LA LINEA DE CORRIENTE DE UNA SEÑAL DE ENTRADA DE VIDEO (Y3) Y DE UN SEGUNDO COMPONENTE DE BAJA FRECUENCIA (Y10) DERIVADO AL PROCESAR LA ADAPTACION DEL MOVIMIENTO (42, 50) DESDE UNA LINEA SELECCIONADA PREVIAMENTE DE LA SEÑAL DE ENTRADA DE VIDEO. UN CIRCUITO DE SALIDA DE LINEA DE DOBLE TASA (30B) QUE COMBINA UNA LINEA DE LA SEÑAL DE DIFERENCIA DE LA LINEA DE DOBLE TASA (Y14) CON CADA UNA DE LAS OTRAS LINEAS DE LA SEÑAL DE ENTRADA DE LA LINEA DE DOBLE TASA (Y4) PARA FORMAR UNA SEÑAL DE SALIDA PROGRESIVAMENTE RASTREADA (Y2). EL SISTEMA EXHIBE VENTAJOSAMENTE, LA RESOLUCION VERTICAL RELATIVAMENTE ALTA Y LA CARACTERISTICA DE INMUNIDAD DEL ARTEFACTO DEL MOVIMIENTO DE LOS SISTEMAS DE ADAPTACION DEL MOVIMIENTO ASI COMO LAS CARACTERISTICAS DE LOS REQUISITOS DE MEMORIA DEL SISTEMASUSTANCIALMENTE REDUCIDOS DE LOS PROCESADORES DE "DOS BANDAS" Y PROPORCIONA EL PROCESAMIENTO DE "DOS BANDAS" DE LOS COMPONENTES DE VIDUO DE ALTA Y BAJA FRECUENCIA SIN NECESIDAD DE FILTROS DE SEPARACION DE BANDAS COMPLEMENTARIOS PROVISTOS DE LAS CARACTERISTICAS DE AMPLITUD Y DE RESPUESTA DE FASES ESPECIALES.
