Abstract
EN UN METODO DEPENDIENTE DEL COLOR QUE REDUCE LA LUMINANCIA CRUZADA, SE SUMINISTRAN COMPONENTES DE LA SEÑAL DE CROMINANCIA PROMEDIADA DENTRO DE LA TRAMA (U{SUB,IFA},V{SUB,IFA}) DE ACUERDO CON LAS COMPONENTES DE LA SEÑAL DE CROMINANCIA (U,V). SUBSECUENTEMENTE, UNA SEÑAL DE CONTROL DE FILTRADO DE REDUCCION DE LA LUMINANCIA CRUZADA SE SUMINISTRA (3,5) EN BASE A LAS COMPONENTES DE SEÑAL DE CROMINANCIA PROMEDIADA DENTRO DE LA TRAMA (U{SUB,IFA},V{SUB,IFA}), Y LA SEÑAL DE LUMINANCIA SE FILTRA (1) EN BASE A LA SEÑAL DE CONTROL DE FILTRADO DE REDUCCION DE LUMINANCIA CRUZADA PARA PRODUCIR UNA SEÑAL DE LUMINANCIA DE SALIDA (Y{SUB,OUT}).
