Abstract

EN SISTEMAS DE TV TIPO SECAM, MAC, MUSE, ETC. LAS SEÑALES DE CROMINANCIA SON TRANSMITIDAS EN LINEAS ALTERNAS. SE DEBEN TENER EN CUENTA UNA SERIE DE PRECAUCIONES PARA EVITAR LOS ARTEFACTOS DE CONMUTACION DE COLORES, PERO ESTAS PRECAUCIONES NO SE TOMAN EN TODOS ESTOS SISTEMAS ESTANDAR. SEGUN LA INVENCION, LA SEÑAL DE CROMINANCIA SE PUEDE PREFILTRAR ANTES DE UNA OMISION DE LINEAS ALTERNAS Y POST-FILTRAR PARA UNA VISUALIZACION DE LINEAS COMPLETAS. EL FILTRO ADAPTIVO DE LA INVENCION PARA MEJORAR LA CALIDAD DE LA IMAGEN UTILIZA INFORMACION ADICIONAL PROCEDENTE DE LOS OTROS COMPONENTES DE COLOR O INCLUSO DE LA SEÑAL DE LUMINANCIA.
