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 collecting method and device, as well as a mobile terminal. The fingerprint collecting method comprises the following steps: when fingerprint contact of a user is detected, collecting a fingerprint image of the user, and extracting a fingerprint feature in the fingerprint image; when a fingerprint template fitted with the fingerprint feature is found in a fingerprint database, obtaining a distinctive feature between the fingerprint feature and the fitted fingerprint template while executing fingerprint unlocking operation; correcting the fingerprint template according to the distinctive feature; and replacing the distinctive feature with the corrected distinctive feature. Accordingly, a sampled fingerprint is collected while the user performs fingerprint operation; correction of the fingerprint template is realized by adding the distinctive feature between the sampled fingerprint and the fingerprint template into the fingerprint template, so that the fingerprint template can be improved constantly to improve the fitting rate between a fingerprint entered when the user performs fingerprint unlocking and the fingerprint template, and the sensitivity of fingerprint unlocking is further improved.

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...
