Abstract

UN APARATO Y METODO PROCESADOR DE SEÑALES DE VIDEO PARA CONVERTIR UNA SEÑAL DE VIDEO DE UNIDAD DE IMAGEN EN UNA SEÑAL DE VIDEO DE UNIDAD DE CAMPO QUE INCLUYE UNA MEMORIA (116) PARA ALMACENAR LA SEÑAL DE VIDEO DE UNIDAD DE IMAGEN, UN CIRCUITO DE CONTROL (31) PARA CONTROLAR LA LECTURA DE LOS DATOS DE VIDEO DE UNIDAD DE IMAGEN ALMACENADOS DE LA MEMORIA PARA OBTENER LA SEÑAL DE VIDEO DE UNIDAD DE CAMPO CON CAMPOS DISTRIBUIDOS EN UN ORDEN DESEADO, Y UN FILTRO VERTICAL (32) QUE RECIBE LA SEÑAL DE VIDEO DE UNIDAD DE CAMPO LEIDA DESDE LA MEMORIA. EL FILTRO VERTICAL DESPLAZA UN CENTROIDE DE IMAGEN REPRESENTADA POR UNA SEÑAL DE VIDEO RECIBIDA DE ACUERDO CON AL MENOS UN COEFICIENTE QUE ES SELECCIONADO CON RESPECTO AL ORDEN DEL CAMPO. LA LECTURA DE LA SEÑAL DE VIDEO PUEDE CONTROLARSE PARA OPERAR COMO UN DISPOSITIVO DE RETARDO ELIMINANDO ASI LA NECESIDAD PARA TAL RETRASO EN EL FILTRO VERTICAL. CUANDO SE APLICA A UN VTR DIGITAL O SIMILAR, EL PRESENTE APARATO EVITA LAS INTERFERENCIAS DE LINEA Y SUPRIME LAS VIBRACIONES DE PLANO.
