Abstract

FILTRO HORIZONTAL PARA UNA SEÑAL DE LUMINISCENCIA Y DE CAROMINISCENCIA PARA LA PRODUCCION DE UNA IMAGEN REDUCIDA. PARA LA REPRODUCCION DE UNA IMAGEN EN IMAGEN PRINCIPAL SE EXPLORA LA IMAGEN, QUE SE REPRODUCE Y MEDIANTE FILTRACION SE PRODUCE UNA RELACION DE COMPRESION CORRECTA. ADEMAS ES NECESARIO UN MULTIPLEXER RAPIDO Y UNA CUOTA EXPLORADORA ALTA. PARA LA COMPRESION HORIZONTAL DE UNA SEÑAL VIDEO, QUE ENTRA, SE EXPLORAN PRUEBAS DE SEÑAL DE LUMINISCENCIA Y DE CROMINISCENCIA Y SE SOMETE EN UN FILTRO DE LA FORMACION DEL VALOR MEDIO. APLICACION EN APARATOS DE REPRODUCCION DE IMAGENES.
