Embodiment Construction

[0070] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0071] The embodiment of the present invention discloses a fingerprint collection method, device and mobile terminal, so as to realize the collection of fingerprint samples while the user is using fingerprint operations, and to realize the fingerprint template by adding the difference between the fingerprint sample and the fingerprint template to the fingerprint template. The revision of the fingerprint template can improve the matching degree between the finge...

Abstract

The invention discloses a fingerprint collection method, device and mobile terminal. When the user's fingerprint contact is detected, the user's fingerprint image is collected, and the fingerprint features in the fingerprint image are extracted. When matching the fingerprint template, while performing the fingerprint unlocking operation, obtain the difference between the fingerprint feature and the matched fingerprint template, correct the fingerprint template according to the difference feature, and replace the corrected fingerprint template with the corrected fingerprint template. It can be seen that the present invention collects fingerprint samples while the user uses the fingerprint operation, and adds the difference between the fingerprint sample and the fingerprint template to the fingerprint template to realize the correction of the fingerprint template, so that the fingerprint template is continuously improved and the user's fingerprint is improved. The matching degree between the fingerprint entered during unlocking and the fingerprint template, thereby improving the sensitivity of fingerprint unlocking.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, and more specifically, to a fingerprint collection method, device and mobile terminal. Background technique [0002] At present, many mobile terminals have the function of fingerprint identification. With the development of technology, the function of fingerprint identification has also developed from the previous single unlocking function to the current functions of unlocking, payment and launching various applications. To protect the security of user information. [0003] Usually, the fingerprint template stored in the fingerprint library of the mobile terminal is collected when the user initiates fingerprint unlocking or initializes the fingerprint. By matching the fingerprint entered when the user fingerprint unlocks with the fingerprint template, the fingerprint is identified, and after the matching is successful to unlock. However, the inventors of the present invention h...
