Patent ID: 8285009

Claim:
A fingerprint input apparatus for inputting a plurality of partial fingerprint images constituting a fingerprint image through a plurality of input times while moving a finger to acquire the fingerprint image, said fingerprint input apparatus comprising a microcomputer, said microcomputer comprising: an operation section configured to determine an intersection of the plurality of input partial fingerprint images, and to calculate a relative location between the plurality of partial fingerprint images on the basis of the intersection; and a communication section configured to output data of the relative location calculated by said operation section and to output the plurality of partial fingerprint images to an external device; wherein said plurality of partial fingerprint images comprises a plurality of prior partial fingerprint images and a latest partial fingerprint image; and said operation section assumes that any one of the plurality of prior partial fingerprint images is an object of the calculation, and one or more remaining prior partial fingerprint images and the latest partial fingerprint image are reference images, and calculates a plurality of relative locations, the plurality of relative locations comprising a relative location between the object of the calculation and each of the reference images, and weights the plurality of relative locations.
