Abstract

En el caso en donde un filtro de desbloqueo aplicado a un componente de luminancia sea referido y aplicado a un componente de crominancia, mediante la conversion de la posicion de pixel del componente de crominancia para asi tener una posicion de pixel del componente de luminancia que pertenezca al mismo campo que el componente de crominancia (F7a) y con referencia al componente de luminancia, la presente invencion hace posible la generacion de una imagen mas natural mediante el filtrado del componente de luminancia y el componente de crominancia con la misma intensidad cuando la imagen sea visualizada en una forma de exploracion por entremezclado.
