Alternatively, terminal determines the feature point number of fingerprint image, is referred to according to the feature point number of fingerprint image with default Difference and/or ratio between the feature point number of line template reduce unblock threshold value.
For example, the feature point number of fingerprint image is A, the feature point number of preset fingerprint template is B, and unblock threshold value is C, Unblock threshold value=C* (B-A)/B after reduction, in specific calculating process, if the unblock threshold value after reducing is less than minimum unblock threshold Value, in this case, can be directly using minimum unblock threshold value as the unblock threshold value after reducing.
In another example, it may be determined that the feature point number of fingerprint image and the feature point number of preset fingerprint template, according to both Feature point number difference reduce unblock threshold value, for example, difference is in the first preset range, then reduce by 10%, difference is more than First preset range then reduces by 20%.
In another example, it may be determined that the feature point number of fingerprint image and the feature point number of preset fingerprint template, according to both Feature point number ratio reduce unblock threshold value, for example, ratio is in the second preset range, then reduce by 10%, ratio is more than Second preset range then reduces by 20%.Above-mentioned first preset range and the second preset range can be by users according to practical application request Or experience is configured, will not be repeated here.
As can be seen that terminal described in the embodiment of the present invention can when detecting that user presses fingerprint recognition module, Since the default collection point of fingerprint recognition module, pixel is gathered along default diagonal, in the pixel of collection Collection area is when being more than predetermined threshold value, the pixel composite finger picture that will be collected, and can be wet finger in fingerprint image During the image of image or dry finger, image enhancement processing is carried out to fingerprint image, then, by fingerprint image and preset fingerprint mould Plate is matched, and in fingerprint image and the success of preset fingerprint template matches, terminal is unlocked, or, in fingerprint image During the image of the image for wet finger and dry finger, directly fingerprint image is matched with preset fingerprint template, matched During success, terminal is unlocked.So as to due to diagonally gathering fingerprint image, and only gather predetermined threshold value The fingerprint image of size, it is therefore possible to shorten the fingerprint image acquisition time, you can improve terminal unlocking efficiency.Also, can be in user Finger is wet when filtering or drying, and carries out certain enhancing to fingerprint image and handles, can improve the quality of fingerprint image, so as to can More characteristics of image are obtained from the fingerprint image after enhancing processing, fingerprint matching efficiency can be improved, that is, improve fingerprint solution Lock efficiency.
