Fingerprint detecting method

Abstract

The claimed invention discloses a fingerprint detecting method. Firstly, providing an object, sliding the object on the image capturing area, and making the image capturing area sequentially producing a plurality of first images to the image processor in a measure period. The image processor sequentially compares overlaps of each first image and produces a first moving rate. The image capturing area uniformly captures images with the first moving rate and produces a plurality of second images to the image processor. The image processor sequentially combines each second image to form a fingerprint image. The claimed invention can effectively lower the arithmetic while combining images, reduce the probability of fingerprint image distortion, and improve the fingerprint identification rate.
