Patent ID: 7706581

Claim:
A method of detecting skinprints, in particular fingerprints, characterized in that at least one strip sensor comprising at least one elongate narrow sensor line detects the structure of the fingertip when the fingertip passes over the strip sensor, at least one optoelectronic speed sensor continuously determines finger movement, the fingertip is moved over at least one optoelectronic speed sensor and the strip sensor, and the determined finger movement is used to correct an image of the finger structure that has been distorted as a result of non-uniform movement, wherein a movement sequence takes place such that the same regions of the fingertip pass over the strip sensor a number of times and are detected as images, and the image information detected a number of times for one region is taken into account for image improvement purposes, at least part of the spatial allocation of the image information taking place through the detected movement sequence.
