Abstract

ARTEFACTOS DE LUMINANCIA CRUZADA Y DE DIAFOTIA CROMATICA SE PUEDEN ELIMINAR SI EN UN DESCODIFICADOR EXTENDIDO SE IGUALA A MODO DE PAREJAS LA INFORMACION DE CROMINANCIA EN DOS INSTANTES DE TIEMPO Y LA INFORMACION DE LUMINANCIA (ES DECIR, LAS ALTAS FRECUENCIAS HORIZONTALES) SE IGUALA TAMBIEN EN ESTOS DOS INSTANTES DE TIEMPO. EN UN DESCODIFICADOR EXTENDIDO, LA INFORMACION DE LUMINANCIA DE ALTA FRECUENCIA SE PUEDE VOLVER A SEPARAR DE LA INFORMACION DE CROMINANCIA MODULADA SI, POR EJEMPLO, (I) SE RESTA LA INFORMACION DE LAS PAREJAS EN LOS INSTANTES DE TIEMPO ARRIBA MENCIONADOS Y SE DIVIDEN POR 2 (LO CUAL DA LUGAR A LA CROMINANCIA) Y SI (II) SE CALCULA EL VALOR MEDIO DE LA INFORMACION DE LAS PAREJAS EN ESTOS INSTANTES DE TIEMPO (LO QUE DA LUGAR A LA LUMINANCIA DE ALTA FRECUENCIA).
