Abstract

UN PRIMER PIXEL (YA) DE UN CAMPO DADO SE COMPARA CON UN SEGUNDO (YB) Y UN TERCER (YC) PIXELES VERTICALMENTE ALINEADOS DE LA POSICION HORIZONTAL CORRESPONDIENTE DE UN CAMPO ADYACENTE PARA PRODUCIR, PARA CADA PRIMER PIXEL, UNA SEÑAL DE DIFERENCIA DE PIXEL (PD) QUE TIENE UN VALOR DE CERO SI EL VALOR DEL PRIMER PIXEL ES INTERMEDIO A LOS VALORES DEL SEGUNDO Y EL TERCER PIXELES, LA SEÑAL DE DIFERENCIA TENDRA DE OTRA FORMA UN VALOR IGUAL AL VALOR ABSOLUTO DE LA DIFERENCIA ENTRE EL VALOR DEL PRIMER PIXEL Y EL VALOR DE UNO DE ENTRE EL SEGUNDO Y EL TERCER PIXEL QUE TENGA EL VALOR MAS CERCANO AL DEL PRIMER PIXEL. LAS SEÑALES DE DIFERENCIA DE PIXELES SON ACUMULADAS A LO LARGO DE UNA PARTE PREDETERMINADA DE UN PERIODO DE CAMPO DE LA SEÑAL DE VIDEO PARA SUMINISTRAR UNA SEÑAL DE DIFERENCIA DE CAMPO (SN) QUE ES ANALIZADA POR UN GRUPO DE CINCO CORRELACCIONADORES PARA BUSCAR LAS CARACTERISTICAS DE FUENTES DE MODOS DE PELICULAS DE ARRASTRE DE 2-2 Y DE ARRASTRE 3-2. SE PRODUCEN UNAS MARCAS PARA IDENTIFICAR ELFUNCIONAMIENTO EN MODO DE PELICULA (FILM MODE) Y PARA IDENTIFICAR CUAL DE LOS CAMPOS ADYACENTES SE USARA EN UN PROCESAMIENTO DE VIDEO SUBSECUENTES (FILM FIELD IDENTIFIER) TAL COMO EL DESENTRELAZADO O LA REDUCCION DE LAS OSCILACIONES.
