Abstract

PROCESO PARA LA REDUCCION DE RUIDO EN SEÑALES DE TELEVISION O VIDEO POR MEDIO DE UNA DISPOSICION CON UN CIRCUITO (1) DE REDUCCION DE RUIDO, CUYA PRIMERA SEÑAL (DIN) DE ENTRADA ES UNA SEÑAL DE TELEVISION O VIDEO Y CUYA SEGUNDA SEÑAL (DMEM) DE ENTRADA ES UNA SEÑAL (DOUT) DE SALIDA DEL CIRCUITO (1) DE REDUCCION DE RUIDO CON PARTE DE BAJA FRECUENCIA RETARDADA EN LA DIRECCION DE UNA SEMI-IMAGEN. SE DISPONE DE UN ACUMULADOR (2) PARA EL RETARDO DE LA PORCION DE BAJA FRECUENCIA DE LA SEÑAL (DOUT) DE SALIDA CON RESPECTO A LA DURACION DE UNA SEMIIMAGEN, DE UN FILTRO (3;31,33) DE DECIMACION CONECTADO PREVIAMENTE CON EL ACUMULADOR PARA LA REDUCCION DE LA TASA DE DATOS Y CON UN FILTRO (4;41,42) DE INTERPOLACION CONECTADO POSTERIORMENTE CON EL ACUMULADOR (2) PARA LA ELEVACION DE LA TASA DE DATOS.
