The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The mobile terminal described in the embodiment of the present invention may include a smart Phone (such as an Android Phone, an iOS Phone, a Windows Phone, etc.), a tablet computer, a palm computer, a notebook computer, a mobile internet device (MID, mobile internet Devices), or a wearable device, and the mobile terminal is merely an example, and is not exhaustive and includes but is not limited to the mobile terminal.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a mobile terminal 100 according to an embodiment of the present invention, where the mobile terminal 100 includes: application processor AP110, touch-control display screen 120 and fingerprint identification module 130, application processor 110 passes through bus 140 and connects touch-control display screen 120 and fingerprint identification module 130, wherein:
in this embodiment, the touch display screen 120 is configured to, at the fingerprint registration stage, acquire a first pressure value corresponding to a first touch operation if the first touch operation directed to the fingerprint identification module is detected, and notify the fingerprint identification module to perform fingerprint acquisition.
The touch display screen 120 may detect a touch operation on the display screen, and perform a corresponding operation according to a display screen area corresponding to the touch operation, for example, slide unlocking, fingerprint payment, target image selection, and the like. The touch display screen 120 may also obtain a pressure value corresponding to the current touch operation, so as to determine whether to execute the corresponding operation, for example, pressing an icon with force may pop up a semi-transparent menu, which includes some shortcut operations under the application; and lightly pressing the icon can enter a default interface of the application corresponding to the icon, and the like. The touch display screen 120 may further obtain a current state of the mobile terminal to control on or off of a light of the display screen, for example, the mobile terminal is lifted up to turn on the display screen, or a preset time period is waited for until no operation light is received, and the like.
In this embodiment, in the fingerprint registration stage, if the first touch operation on the fingerprint identification module 130 is detected, the touch display screen 120 acquires a first pressure value corresponding to the first touch operation, and notifies the fingerprint identification module 130 to perform fingerprint acquisition on the first touch operation.
In this embodiment, the fingerprint identification module 130 is used for acquiring a first fingerprint image corresponding to the first touch operation, and sending the first fingerprint image to the AP.
The present implementation is not limited to the particular method of capturing the fingerprint image.
In this embodiment, the AP110 is configured to perform image quality evaluation on the first fingerprint image to obtain an image quality evaluation value, and when the image quality evaluation value is greater than a first threshold, take the first pressure value as a reference pressure value.
Wherein, the reference pressure value is used for the pressure threshold as fingerprint collection, that is to say, when the pressure value of touch operation is greater than or equal to the pressure threshold, then the fingerprint image of fingerprint identification module 130 collection is clear. The first threshold is a preset constant, and is a critical value for judging whether the first fingerprint image is clear. The image quality evaluation is to evaluate the image quality of the first fingerprint image, thereby obtaining an image quality evaluation value, and when the image quality evaluation value is greater than a first threshold, the first fingerprint image is considered to be clear, and when the image quality evaluation value is less than or equal to the first threshold, the first fingerprint image is considered to be not clear. It can be understood that the pressure value of touch operation is increased, the contact area between the finger and the screen can be increased, and the problem of poor contact in the ridge line position can be solved, so that the recognition degree of the fingerprint image and the convenience of operation are improved.
When the image instruction evaluation value is smaller than or equal to the first threshold value, the touch display screen 120 prompts the user to perform fingerprint acquisition by adopting a second touch operation larger than the first pressure value, when the fingerprint identification module 130 acquires a second fingerprint image corresponding to the second touch operation and sends the second fingerprint image to the AP110, the AP110 performs image quality evaluation on the second fingerprint image, and when the image quality evaluation value of the second fingerprint image is larger than the first threshold value, the second pressure value is used as a reference pressure value; this step is repeatedly executed when the image quality evaluation value of the second fingerprint image is smaller than the first threshold value.
Optionally, the AP110 is further specifically configured to determine whether the first fingerprint image is a fingerprint image of a dry finger, and perform image quality evaluation on the first fingerprint image when the first fingerprint image is the fingerprint image of the dry finger. That is to say, the embodiment of the present invention is directed to a fingerprint registration method for a dry finger, and image quality evaluation is performed on a first fingerprint image only when it is determined that a finger corresponding to the first fingerprint image is a dry finger.
Optionally, the determining, by the AP110, whether the first fingerprint image is a fingerprint image of a dry finger is specifically as follows: the AP110 is further configured to obtain the number of discontinuous grain features in the first fingerprint image, and when the number is greater than the second threshold, confirm that the first fingerprint image is a fingerprint image of a dry finger.
The second threshold is a preset constant, and is a critical value for judging whether the first fingerprint image is a fingerprint image of a dry finger. Because the fingerprint image in the dry finger may have disconnected grain features, whether the finger is a dry finger can be judged according to the number of the discontinuous grain features in the first fingerprint image.
For example, assuming that the second threshold is 5, as shown in the fingerprint image of fig. 2, the number of discontinuous grain features in the first fingerprint image is 6, and since 6>5, the first fingerprint image is determined to be the fingerprint image of the dry finger.
Optionally, the fingerprint acquisition module 130 may further obtain a moisture content of the finger corresponding to the first touch operation, and when the moisture content is less than or equal to a third threshold, determine that the first fingerprint image is a fingerprint image of a dry finger.
When subsequent fingerprint collection, as long as the pressure value is greater than the reference pressure value, AP110 just can inform fingerprint identification module 130 to carry out fingerprint collection, can avoid the mistake to touch fingerprint identification module 130 to improve the image quality value of fingerprint image.
Optionally, the AP110 is further configured to store a first fingerprint image, and the first fingerprint image is used to generate a fingerprint template. After the first fingerprint image is stored, all subsequent fingerprint registration images are larger than the reference pressure value, the fingerprint image can be collected, and when the collected fingerprint images meet the specified number, the first fingerprint image and the subsequent fingerprint images are processed to generate the fingerprint template.
For example, assuming that the fourth threshold is 2, after the first fingerprint image is collected, it is determined that the first pressure value corresponding to the first touch operation is the reference pressure value, a second fingerprint image corresponding to the second touch operation and a third fingerprint image corresponding to the third touch operation are collected respectively, where both the second pressure value corresponding to the second touch operation and the third pressure value corresponding to the third touch operation are greater than the reference pressure value, and image processing is performed according to the first fingerprint image, the second fingerprint image, and the third fingerprint image to generate the fingerprint template.
Optionally, the touch display screen 120 is further configured to detect a second touch operation on the fingerprint identification module 130, obtain a second pressure value corresponding to the second touch operation, and send the second pressure value to the AP 110; the AP110 is further configured to compare the second pressure value with the reference pressure value, and notify the fingerprint identification module 130 to perform fingerprint acquisition when the second pressure value is greater than the reference pressure value; the fingerprint identification module 130 is further configured to collect a second fingerprint image corresponding to the second touch operation, and send the second fingerprint image to the AP 110; the AP110 is further configured to match the second fingerprint image with the fingerprint template, and when the second fingerprint image is successfully matched with the fingerprint template, confirm that the identity authentication of the second fingerprint image is successful.
That is, the second touch operation may be an operation for identity authentication of fingerprint unlocking, fingerprint payment, account login, or the like. When the user performs the second touch operation and the second pressure value is greater than the reference pressure value, the fingerprint identification module 130 collects the second fingerprint image, the second fingerprint image is successfully matched with the fingerprint template, and the identity authentication of the second fingerprint image is successfully confirmed.
For example, assuming that the reference pressure value is 20, when the screen is locked, the user performs a second touch operation on the fingerprint identification module 130, the touch display screen 120 obtains a second pressure value corresponding to the second touch operation as 25, and the AP110 determines that 25 is greater than 20, notifies the fingerprint identification module 130 to acquire a second fingerprint image corresponding to the second touch operation, and the AP110 performs an unlocking operation when the second fingerprint image is successfully matched with the fingerprint template.
In the mobile terminal described in fig. 1, in the fingerprint registration stage, if the touch display screen 120 detects a first touch operation on the fingerprint identification module 130, a first pressure value corresponding to the first touch operation is obtained, the fingerprint identification module 130 collects a first fingerprint image corresponding to the first touch operation, the AP110 performs image quality evaluation on the first fingerprint image to obtain an image quality evaluation value, and when the image quality evaluation value is greater than a first threshold, the first pressure value is used as a reference pressure value. If the reference pressure value is used as the pressure threshold value for fingerprint collection, the image quality evaluation value of the collected fingerprint image is greater than or equal to the image quality evaluation value of the first fingerprint image as long as the touch operation is greater than or equal to the reference pressure value, so that the recognition degree of the fingerprint image and the convenience of the operation are improved.
Referring to fig. 3, fig. 3 is a schematic flowchart of a fingerprint registration method according to an embodiment of the present invention, and the fingerprint registration method is applied to a mobile terminal including an application processor AP, a touch display screen, and a fingerprint identification module. Specifically, the method comprises the following steps:
step 301: the mobile terminal controls the touch display screen at a fingerprint registration stage, and if a first touch operation aiming at the fingerprint identification module is detected, a first pressure value corresponding to the first touch operation is acquired, and the fingerprint identification module is informed to perform fingerprint acquisition.

Step 303: the mobile terminal carries out image quality evaluation on the first fingerprint image through the AP to obtain an image quality evaluation value, and when the image quality evaluation value is larger than a first threshold value, the first pressure value is used as a reference pressure value which is used as a pressure threshold value for fingerprint collection.
Optionally, before the mobile terminal performs image quality evaluation on the first fingerprint image through the AP, the method further includes: the mobile terminal judges whether the first fingerprint image is the fingerprint image of the dry finger or not through the AP, and executes the step of evaluating the image quality of the first fingerprint image when the first fingerprint image is the fingerprint image of the dry finger.
