Abstract: A portable and lightweight fingerprint scanning apparatus which can optically scan and record fingerprint images in the field and transmit said images to a mobile unit for processing and subsequent wireless transmission to a central location for the purpose of providing immediate identity and background checks on the individual being fingerprinted. The apparatus of the present invention includes a fingerprint scanner for capturing a fingerprint image, a camera for capturing a photographic image of a person or a scene and means for transmitting the fingerprint image and the photographic image to a mobile unit. In the preferred embodiment the present invention includes a highly integrated camera with a superior signal to noise ratio and an infrared lighting source for illuminating a person or scene in low ambient light situations. An especially preferred embodiment of the present invention also provides the ability to preview the fingerprint and 'mug shot' images on a display screen and to control transmission and processing of the fingerprint and 'mug shot' images by the mobile unit using a terminal or keypad located on the portable fingerprint scanning apparatus.

Abstract: The present invention provides an optical system operable in eliminating parallax distortion in a captured image. Specifically, the apparatus eliminates parallax distortion in a palm print image. The apparatus includes a prism having a receiving surface and an object surface. A palm is placed on the receiving surface and a light illuminates the receiving surface so that an image representative of the palm is propagated from the object surface. The propagated image includes a plurality of segments. A lens selectively magnifies each of the segments by a different amount, as to create a plurality of magnified segments of equal length. A image recording medium then captures the magnified segments. The invention also provides a cylindrical device operable in capturing the image of the palm, where the palm may be rolled across a transparent cylinder and reflected light is captured by a recording medium representative of the palm print.

Abstract: A finger drying component for use with a finger print image processing apparatus is disclosed. The drying component removes moisture from the finger so that an unsmudged finger print can be imaged. A preferred embodiment involves the use of a forced air dryer to conduct a stream of air across the optical imaging surface.

Abstract: La presente invencion proporciona un sistema optico operable para eliminar la distorsion por paralaje en una imagen capturada. Específicamente, el aparato elimina la distorsion por paralaje en una imagen de la huella de la palma. El aparato incluye un prisma que tiene una superficie de recepcion y una superficie de recepcion y una luz ilumina la superficie de recepcion de modo que una imagen representativa de la palma es propagada desde la superficie del objeto. La imagen propagada incluye una pluralidad de segmentos. Un lente amplifica selectivamente cada uno de los segmentos en una cantidad diferente, para crear una pluralidad de segmentos amplificados de igual longitud. Un medio de registro de la imagen captura entonces los segmentos amplificados. La invencion también proporciona un dispositivo cilíndrico operable para capturar la imagen de la palma, en donde la palma puede ser girada a través de un cilindro transparente y la luz reflejada es capturada por un medio de registro representativo de la impresion o huella de la palma.
