Abstract

DISPOSITIVO DE ELABORACION DE LA SEÑAL DE DETALLE VERTICAL DE IMAGENES DE VIDEO. CONSTA DE UN FILTRO DE PASO BAJO (22) A CUYA ENTRADA LE LLEGA UNA SEÑAL DE LUMINANCIA PROCEDENTE DEL FILTRO DE PEINE (15); PASA TODAS LAS SEÑALES DE LUMINANCIA POR DEBAJO DE UNA FRECUENCIA DE CORTE DE 4 MHZ Y ELIMINA LOS COMPONENTES DE RUIDO Y DE FRECUENCIA DE CRONOMETRACION. DE UN FILTRO DE DETALLE VERTICAL DE PASO BAJO (35), A CUYA ENTRADA LE LLEGA UNA SEÑAL DE CROMINANCIA PROCEDENTE, TAMBIEN, DEL FILTRO DE PEINE (15) Y PASA LAS FRECUENCIAS DE LA SEÑAL POR DEBAJO DE 1,8 MHZ. DE UNA RED DE COMBINACION (60), QUE COMBINA LAS SEÑALES DE RESTABLECIMIENTO DE DETALLE VERTICAL DEL TRAYECTO (A) CON LAS SEÑALES DE INTENSIFICACION DE DETALLE VERTICAL DEL TRAYECTO (B), SALE ELABORADA LA SEÑAL DE DETALLE VETICAL.
