Abstract

A motion detection method of a one-dimensional fingerprint detection module is disclosed, which could sense a motion of a test finger. The present invention utilizes a first linear sensing component array and a second linear sensing component array to read a reference image data sequence and a comparison image data sequence from the test finger, operates and compares the reference image data sequence and the comparison image data sequence, and analyzes a moving direction of the test finger according to a comparison result. Another motion detection method of a one-dimensional fingerprint detection module of the present invention comprises the steps of: providing a linear sensing component array for the one-dimensional fingerprint detection module, respectively setting a first image sensing area and a second image sensing area on two ends of the linear sensing component array so as to detect the test finger and retrieve its image data, and then determining the motion of the test finger by means of operating and analyzing the image data.
