Abstract

EL PROCEDIMIENTO, Y EL DISPOSITIVO CORRESPONDIENTE, DE INTERPOLACION TEMPORAL DE IMAGENES, CON COMPENSACION DE MOVIMIENTO CORREGIDA SEGUN EL INVENTO EFECTUA MEDIANTE UN CIRCUITO DE ANALISIS DE COHERENCIA (40) UN ANALISIS DE LOS DEFECTOS DEL CAMPO DE MOVIMIENTO EMITIDO POR EL DISPOSITIVO DE ESTIMACION DE MOVIMIENTO (10) PARA EFECTUAR BIEN LA INTERPOLACION DE MOVIMIENTO COMPENSADO (20), BIEN UNA INTERPOLACION LINEAL (30) SEGUN EL CAMPO DE MOVIMIENTO SE ESTIME CORRECTO O DEFECTUOSO PARA EL PUNTO CORRIENTE DE LA TRAMA A INTERPOLAR. PREFERENTEMENTE, PARA EVITAR UN ACONMUTACION ABRUPTA ENTRE LOS DOS MODOS DE INTERPOLACION, UN CIRCUITO (50,60) PERMITE ENCONTRAR VALORES INTERMEDIOS QUE TIENEN EN CUENTA LOS DOS MODOS DE INTERPOLACION EN LAS ZONAS DE TRANSICION. EL INVENTO SE APLICA, ESPECIALMENTE, EN LA CONVERSION DE ESTANDARES.
