Step 202: when a fingerprint image is collected, the processor determines a reference point of the fingerprint collection area touched by the finger, and determines the average sensitivity of a first area, wherein the center of the first area is the reference point, the area of the first area is a first preset area, and the first preset area is smaller than the area of the fingerprint collection area.
The reference point of the finger touch fingerprint acquisition area is a central touch point of the finger touch fingerprint acquisition area.
Further, the specific implementation manner of the processor determining the reference point of the finger touching the fingerprint acquisition area includes: the processor determines a reference point of the finger touching the fingerprint acquisition area based on a touch signal, wherein the touch signal is sent by the TP when a touch operation of the finger on the fingerprint acquisition area is detected.

The first predetermined area may be, for example, 20 × 20pix, 25 × 25pix, 30 × 30pix, or other values.
Further, the processor determines the average sensitivity of the first region by: the processor acquires the light sensitivity of each pixel point contained in the first area through the fingerprint sensor, and calculates the average light sensitivity of the first area based on the acquired light sensitivity of each pixel point. For example, the first region includes 50 pixels, and the average sensitivity of the first region is an average of the sensitivities corresponding to the 50 pixels.
Step 203: when the light sensitivity of N pixel points among the pixel points in the second region is greater than or equal to the target light sensitivity, the processor adds the collected fingerprint image to a fingerprint template library, the fingerprint collection region comprises a second region, the area of the second region is a second preset area, the second preset area is greater than the first preset area, the target light sensitivity is related to the average light sensitivity, the target light sensitivity is greater than the average light sensitivity, the N is less than a preset threshold, and the preset threshold is an integer greater than 0.
The second area is a preset area, and the center point of the second area may be the reference point, or the center point of the second area is the center point of the fingerprint acquisition area, which is not limited herein. The second predetermined area may be, for example, 80 × 80pix, 90 × 90pix, 100 × 100pix, or any other value.
The target sensitivity = the average sensitivity + a predetermined sensitivity, such as 600nix, 650nix, 700nix, 800nix, 900nix, or other values.

When under the highlight scene, because ruddiness and infrared light can penetrate certain flesh thickness (that is the finger border very penetrates very easily) to make the line of this regional finger very shallow, cover the line even, type the fingerprint under this kind of condition, probably influence the instruction of the fingerprint image of type, influence follow-up fingerprint identification. In this application embodiment, when confirming that the fingerprint is input and is not influenced by the highlight, just in storing the fingerprint image who gathers to the fingerprint template storehouse, avoided taking the unqualified fingerprint image of quality as the fingerprint template, and then promoted follow-up fingerprint identification's identification rate. In addition, when the fingerprint image is collected, the determining action is executed, and the fingerprint input duration can be shortened.
In an implementation manner of the present application, the method further includes:

Wherein the prompt operation comprises at least one of: vibration prompt operation, voice prompt operation, text prompt operation and video prompt operation. The content of the prompt operation may be preset or customized, and is not limited herein.
Therefore, when the fact that fingerprint input is affected by strong light is determined, the collected fingerprint images are removed, the fingerprint images with unqualified quality are prevented from being used as fingerprint templates, and the recognition rate of subsequent fingerprint recognition is improved.
In an implementation manner of the present application, before the processor culls the fingerprint image, the method further includes:
the processor determining a sharpness of the fingerprint image;
the processor adds the fingerprint image to the fingerprint template library under the condition that the definition of the fingerprint image is greater than or equal to a preset definition;
under the condition that the definition of the fingerprint image is smaller than the preset definition, the processor analyzes the fingerprint image to obtain a plurality of fingerprint characteristics; the processor adds the fingerprint image to the fingerprint template library if the number of the plurality of fingerprint features is greater than or equal to a preset threshold; and under the condition that the quantity of the fingerprint features is smaller than the preset threshold value, the processor rejects the fingerprint image and carries out prompt operation, wherein the prompt operation is used for prompting to re-enter the fingerprint.
Wherein the fingerprint features include global features and local features. The overall characteristics include the shape of the pattern, the pattern area, the core point, the triangular point, the number of the patterns and the like. Local features are direction, curvature, position, etc. The pattern refers to the direction and distribution of the ridge line, and is generally classified into circular (also called bucket), arc and spiral. The pattern area is an area on the fingerprint including the overall features, from which it can be discriminated which type the fingerprint belongs to. The core point is located at the progressive center of the fingerprint lines and serves as a reference point when the fingerprint is read and compared. The triangle point is located at the first bifurcation or breakpoint from the core point, or at the convergence, solitary point, turning point of the two lines, or points to these singular points. The number of lines refers to the number of fingerprint lines in the pattern area. When calculating the fingerprint lines, the core point and the triangle point are connected first, and the number of the intersection of the connecting line and the fingerprint lines can be regarded as the number of the fingerprint lines. The direction is the direction in which the feature point is located with respect to the core point. Curvature refers to the speed at which the direction of the lines changes. The position refers to the position coordinates of the node, which is described by a coordinate system, and it may be absolute coordinates or relative coordinates with respect to a triangular point (or a feature point).
It can be seen that when confirming that fingerprint input is influenced by highlight, if the fingerprint characteristic that the fingerprint image who gathers contains is more, the fingerprint image that will gather is saved to the fingerprint template storehouse in, has avoided as the fingerprint template with unqualified fingerprint image of quality, and then has promoted follow-up fingerprint identification's identification rate.
