Abstract

PARA MEJORAR LA REPRODUCCION DE UNA SEÑAL DE IMAGEN DE VIDEO, SOBRE TODO PARA EVITAR EL PARPADEO EN LOS CANTOS Y EN LAS LINEAS, EL SALTO DE LINEAS Y EL TITILEO EN GRANDES SUPERFICIES, SE CONOCEN DIFERENTES PROCEDIMIENTOS, DEBIENDOSE CAMBIAR DE PROCEDIMIENTO SEGUN LOS MOVIMIENTOS. PARA PODER EVITAR TENER QUE CAMBIAR ENTRE DIFERENTES PROCEDIMIENTOS DEPENDIENDO DEL MOVIMIENTO, UNA IMAGEN REGISTRADA PROGRESIVAMENTE SE DIVIDE EN VARIAS IMAGENEES, FORMANDOSE LA SEGUNDA IMAGEN CON LOS MEDIOS ARITMETICOS DE LAS LINEAS ACTUALES, CON LAS LINEAS PREVIAS. AMBAS IMAGENES SE REPRODUCEN CON LA DOBLE FRECUENCIA DE REPETICION DE IMAGEN COMO IMAGEN ORIGINAL.
