The key 2 is specifically to move to the left or to the right. For example, if two consecutively captured fingerprint images in the above picture have a left blank area, the determination module 32 determines that the user's finger moves to the left on the fingerprint recognition key 2, and if two consecutively captured fingerprint images exist, In the right blank area, the judging module 32 determines that the user's finger moves to the right on the fingerprint. ^ It should be noted that when the user moves the finger on the fingerprint recognition key 2 of the electronic device 1, the fingerprint image continuously photographed by the electronic device 1 within the above-mentioned time is not 201028931, and all of the months are all blank areas. If there is no finger blank area continuously photographed in the above-mentioned photographed fingerprint sheet, for example, if the image of the blank area is discontinuous in the fingerprint image taken by the electric search i, the determination module 32 determines the Whether there is a blank picture in the fingerprint image taken. , ', only if there is no blank picture in the fingerprint picture taken continuously, it is judged that the finger of the user is moved up and down on the fingerprint key 2 . _, _ ❹ 、 , , and 32 compare the pictures taken continuously in the time period with the image stored in the database 4 to determine whether the user's finger moves specifically or downwardly on the fingerprint recognition key 2 . As shown, the determination module 32 records the corresponding position of the fingerprint image in FIG. 5 and the picture 1 in the fingerprint image as L1, and then the correspondence between the fingerprint image in the picture 4 and the picture in the original fingerprint image. The location is L2. If L1 is above L2, the determination module 32 determines that the user: fingerprint identification key 2 is up. Conversely, if u is below u' = module 32 determines that the user's finger is moving downward on the fingerprint recognition key 2. If there is a blank in the continuously photographed fingerprint, the shutdown mode determines whether there is only one full-fingerprint image in the continuously captured fingerprint image. If the result of the determination is yes, the judging module 32 determines that the user clicks on the option on the current display page of the electronic device 1; the result of the disconnection is no mode = the user is determined to double-click the electronic device! The options on the current display page. The modulo, and 32 calculation module 34 is used to count the moving distance of the finger in the county finger and the _ film for the finger in the front 2-3 picture.
