Abstract

The embodiment of the invention discloses a fingerprint template obtaining method and a related device. The method comprises the following steps of continuously collecting user fingerprint informationfor multiple times to obtain a plurality of fingerprint pictures; outputting the fingerprint input guide information, executing an accumulation reference operation according to the plurality of fingerprint pictures when a touch operation of a user for a preset area is detected, and outputting fingerprint input success information; repeatedly executing the preset operation until the execution completion of the accumulation reference operation is detected in the Nth preset operation execution process, terminating execution of a first operation in the preset operation, and outputting the fingerprint input completion prompt information, wherein the preset operation comprises the following operations of outputting the fingerprint input guide information, detecting a touch operation, and outputting the fingerprint input success information when the touch operation is detected; and storing the target picture obtained according to the accumulation reference operation as a fingerprint template. According to the embodiment of the invention, the fingerprint template input speed can be improved visually, and the fingerprint template acquisition duration can be shortened.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a fingerprint template acquisition method and related devices. Background technique [0002] With the development of mobile communication technology, electronic devices (such as smart phones) are more and more widely used. In order to ensure the security of various data in electronic devices, the fingerprint unlocking function is set, and in order to make the screen of the display screen large enough, The fingerprint module under the optical screen came into being. [0003] At present, since the noise of the fingerprint under the optical screen is far more serious than that of the capacitive fingerprint, the fingerprint needs to be processed when entering the noise. In the end, the user will think that the phone is stuck. Contents of the invention [0004] The embodiment of the present application provides a fingerprint template acquisition method and a...
