摘要： The invention aims at providing personal identification in environments where non-contact is required, with high accuracy even though using a finger vein pattern images unclear and susceptible to positional deviations, wherein it has: a means for acquiring finger vein patterns without contact; a means for carrying out rotational correction using the outline of a finger as a method of taking out a vein pattern contained in the acquired image; a means for normalizing the position of the finger image with reference to the fingertip; a means for acquiring an overall vein pattern statistically by repetitively tracking regions of dark luminance intensities for a desired length from a desired position in the image; a matching means for comparing regions where vein patterns manifest vivid features; and a means for independent matching of subregions and evaluating positional deviations where matching is recognized.

摘要： An identification apparatus that keeps the conditions for imaging uniform among successive identifications and requires a user to perform only a series of simple maneuvers. An identification apparatus comprising a guide member, a light source, and an imaging unit. The guide member includes a pattern or a structure that inspires a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member such as a button switch is preferably located at a position in the guide member at which a fingertip is to be positioned. An optical opening is formed at a position coincident with a position at which a portion of a finger to be imaged for identification should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources.

摘要： A method and an apparatus for searching character image in an image whether the characters are incorporated into an image or separately picked up from a flip card, which are difficult to be detected by the prior art. The invention enables the character strings thereby detected to be searched in a common framework without relying on the language or the character font. An image is chosen, a character region is detected from the frame of the chosen image on the basis of its shape, and a visual feature of the character area is extracted. On the other hand, a character string to be searched for which has been entered by a character input means is drawn as an image, and a visual feature is extracted from the character area image. The visual feature of the obtained character area and the visual feature of the character area image are matched to determine a level of similarity, and the character region containing a character string the level of similarity of which has been determined is outputted.
