Abstract

La invencion propone un sistema de lectura de huellas dactilares que comprende un captador (10, 50) de huellas que tiene una superficie activa, sensible a la presion y a la temperatura de un dedo (11, 53), y en el que la superficie es bastante más pequeña que la superficie de la huella dactilar (52) a leer, efectuándose la lectura cuando el captador y el dedo están en contacto y con un movimiento relativo de deslizamiento del captador y del dedo, uno con respecto al otro. El sistema lleva medios para reconstruir una imagen completa de la huella a partir de las imágenes (10, 11..., in) parciales, suministradas por el captador durante dicho movimiento. De aplicacion particularmente en los dispositivos de identificacion de personas.
