Abstract

SISTEMA DE GRABACION DE IMAGENES QUE COMPRENDE UNA CAMARA ELECTRONICA Y METODO DE GRABACION DE IMAGENES POR MEDIO DE LOS CUALES LA INFLUENCIA EN LA GRABACION DE OBJETOS EN UNA CAMARA ELECTRONICA DE LAS FLUCTUACIONES TEMPORALES EN LA INTENSIDAD DE LA LUZ QUE ILUMINA LOS OBJETOS SE REDUCE SIGNIFICATIVAMENTE, DE FORMA QUE ES POSIBLE LA UTILIZACION DE FUENTES DE LUZ BARATAS PARA ILUMINAR LOS OBJETOS. ASI, SE EXPONE UN METODO DE GRABACION DE IMAGENES PARA GRABAR LA IMAGEN DE OBJETOS ILUMINADOS POR LUZ QUE INCIDE SOBRE ELLOS MEDIANTE UN SISTEMA DE GRABACION DE IMAGENES QUE INCLUYE UNA CAMARA ELECTRONICA, COMPRENDIENDO EL METODO LA SINCRONIZACION DE LA GRABACION DE LA IMAGEN CON LAS FLUCTUACIONES EN LA INTENSIDAD DE LA LUZ DE ILUMINACION Y SE DESARROLLA UN SISTEMA DE GRABACION DE IMAGENES QUE COMPRENDE UNA CAMARA ELECTRONICA Y UN DISPOSITIVO DE SINCRONIZACION PARA SINCRONIZAR LA GRABACION DE LA IMAGEN DE OBJETOS ILUMINADOS CON LAS FLUCTUACIONES DE LA INTENSIDAD DE LA LUZ QUE ILUMINA LOS OBJETOS AGRABAR, DE FORMA QUE LA IMAGEN SE GRABA COMO SI LOS OBJETOS FUERAN ILUMINADOS CON UNA LUZ DE INTENSIDAD TEMPORALMENTE SUSTANCIALMENTE CONSTANTE.
