Abstract

UN DISPOSITIVO ELECTRONICO REPRODUCTOR DE IMAGENES PARA SEÑALES DIGITALES DE VIDEO INCLUYE UNA PANTALLA DIFUSORA DE LUZ PARA LOS LIMITES DE BLOQUES PARA REDUCIR LA VISIBILIDAD DE LOS LIMITES DE BLOQUE EN SEÑALES DE VIDEO. EN EL CASO DE ESPECIFICACIONES DE CALCULO QUE DIFIEREN DE BLOQUE A BLOQUE PARA LOS PUNTOS DE IMAGEN EN BLOQUES DE SEÑALES DE VIDEO, LOS LIMITES DE BLOQUE PUEDEN SER VISIBLES DE FORMA MOLESTA DURANTE LA REPRODUCCION DE CONTENIDOS DE IMAGEN DADOS. LA PANTALLA DIFUSORA DE LUZ PARA LIMITES DE BLOQUES FORMA UNA TRANSICION SUAVE PARA LOS PUNTOS DE IMAGEN EN DICHOS LIMITES DE BLOQUES ENTRE LOS DIFERENTES MODOS DE CALCULO. APLICABLE AL PROCESAMIENTO DIGITAL DE SEÑALES DE IMAGEN.
