Abstract

The invention discloses a fingerprint identification control method. The fingerprint identification control method comprises the following steps: debugging a plurality of first pre-determined gain parameters suitable for dry fingers through a test; calling the plurality of first pre-determined gain parameters according to user input; obtaining a fingerprint image for each first pre-determined gain parameter; and selecting an optimal fingerprint image from the plurality of fingerprint images. Besides, the invention also discloses a fingerprint identification control device and an electronic device. According to the fingerprint identification control method, the fingerprint identification control device and the electronic device, fingerprints of dry fingers or fingers, of which the fingerprint lines are shallow and dry, can be collected through the specially-set gain control parameters, so that the optimal fingerprint image can be obtained quickly to carry out related operation, the effect is good and user experience is improved.

Description

technical field [0001] The invention relates to electronic devices, in particular to a fingerprint identification control method, a fingerprint identification control device and an electronic device. Background technique [0002] The current capacitive fingerprint identification module includes gain control, and the optimal fingerprint image can be obtained by adjusting the gain parameters during fingerprint identification. For example, a fingerprint image is obtained for each gain parameter, and then the optimal fingerprint image is selected. In order to improve the recognition speed or save the space of cached fingerprint images, the gain parameters used are generally tested and suitable for most people's fingerprints. However, for dry fingers, due to the shallow and dry lines, it is generally necessary to use more extreme gain control parameters to obtain the optimal fingerprint image. long. Contents of the invention [0003] The present invention aims to solve at le...
