ABSTRACT:
A method for implementing a navigation key function in a mobile communication terminal using fingerprint-recognition. The mobile communication terminal includes a fingerprint-recognition sensor divided into a plurality of image detection blocks. The method comprises recognizing a fingerprint over at least one of the plurality of image detection blocks, obtaining a directional characteristic corresponding to a direction indicated by the at least one of the plurality of image detection blocks that has recognized the fingerprint, and then determining a directional value based on the obtained directional characteristic to perform a corresponding directional process.
