Abstract: A perfect non-contact type vein authentication apparatus is provided with a light source for emitting infrared light; an input interface equipped with an imaging unit for photographing a vein image of a living body by the infrared light emitted from said light source; a unit for controlling intensity of light to be illuminated; an image calculating unit for performing a feature extracting operation and a feature authenticating operation with respect to an image; and a positioning unit for presenting the living body. More specifically, the light source is provided in front of the living body. Both the light source and the imaging unit are installed in such a positional relationship that the light of the light source gives no adverse influence to the imaging unit. Also, the light source is installed in such a direction that the light of the light source gives no adverse influence to the imaging unit.

Abstract: A compact and highly accurate downward irradiation type finger vein authentication device achieved by providing a structure that stabilizes the finger and also prevents adverse effects caused by the left and right fingers. The finger vein authentication device comprises a center finger stand for mounting the finger for authentication; a light source for irradiating infrared light onto the finger; an image capture unit for capturing an image of the finger veins by way of light from a light source; an aperture to open in the image capture direction of the image capture unit; a storage device to store the finger biological information; an authentication processor unit to extract the features from the image captured by the image capture unit and match the features with the biological information stored in the storage device; and a left and right finger stand for the fingers on the left and right of the finger for authentication.

Abstract: In a finger vein authentication unit and an information processing unit using the same, in order to realize a small size and high accuracy such that the finger vein authentication unit is applied to a small-sized information processing unit such as a mobile telephone, the finger vein authentication unit includes a light source which irradiates infrared light to a finger, an imaging sensor which images a vein image by the light which is diffused in the finger and transmitted through the front side of the finger, and an image processing unit which processes the image. The light source is mounted on the front side of the finger and emits the light toward the side surfaces of the finger.

Abstract: The invention provides a finger vein authentication device using plural fingers that enables the plural fingers to be easily presented while maintaining high authentication precision. A finger vein authentication device according to an embodiment of the invention includes light sources that irradiate light onto fingers; imaging elements that photograph light transmitted through the fingers; and an image processing unit that processes the obtained images. The finger vein authentication device further includes a finger placement table that defines a presentation location of the first finger in an anteroposterior direction and other finger placement tables that define locations of all the fingers in a horizontal direction.

Abstract: There is provided a finger-vein authentication apparatus including a light source for illuminating one surface of both side-surfaces of a fingertip of a finger with light, and an image sensor for imaging the other surface of the fingertip, the light source and the image sensor being positioned at both sides of a nail of the fingertip with the nail sandwiched therebetween, wherein a fingertip guidance jig for supporting the fingertip and a finger-root guidance jig for supporting a finger-root of the finger are disposed between the light source and the image sensor, a light-shielding unit being disposed on the light-source side, the light-shielding unit being used for shielding the illumination light such that the illumination light will not travel to a ball side of the finger.

Abstract: Provided is a finger vein authentication apparatus including a light source for emitting light toward a finger, an image sensor for taking an image of the transmitted light from the finger, a lens apparatus for imaging the transmitted light to the image sensor, and an image processor for processing the taken image. The lens apparatus includes a lens unit, and the image processor extracts a vein pattern of the finger upon correcting the strain of the taken image.

Abstract: Provided is a small-sized, flat, vein authentication device of high authentication accuracy by photographing a living body several times and thus obtaining as registration data plural images that are picked up at different positions. A biometric information processing device of this invention comprising an image pickup device, which picks up a vein image, an image computing unit, which processes the vein image picked up by the image pickup device, an interface on which a part of a living body to be picked up is placed, and a light source, which emits infrared light. The biometric information processing device is further comprised of a sensor unit, which detects the presence or absence of a subject picked up by the image pickup device, a unit to obtain plural images as registration data, and a unit to select optimum registration data out of images obtained as registration data.

Abstract: Personal identification is implemented by picking up finger vein patterns when the user naturally grasps a grip such as doorknob. The device for personal identification has a light source provided to irradiate light on the finger from the palm side, a camera to pick up the vessel image of the finger, and a processor to extract features of the vessel from the image and compare the obtained features with the registered ones. The camera picks up the light that exits from the backside of the finger after penetrating it.
