Description

A method, device and terminal for displaying a fingerprint input image

technical field

The present disclosure relates to the field of fingerprint identification, and in particular, to a method, device, and terminal for displaying a fingerprint input image.

Background technique

At present, users can perform services such as terminal unlocking or payment through the fingerprint recognition function of the smart terminal. Before using the fingerprint recognition function, the user needs to enter the fingerprint template. The user needs to perform fingerprint entry on the fingerprint sensor for a fixed number of times, thereby generating a fingerprint template. Each time the user performs fingerprint entry, the terminal will display a corresponding frame of image in the fingerprint entry animation, so that the user can understand the entry progress of the fingerprint template.

However, different terminal models correspond to different fixed times of fingerprint entry, and the applicable types of fingerprint entry animations are also different. In the related art, in order to adapt to all terminal models, various types of fingerprint entry animations are stored on the terminal at the same time. However, in practical applications, a terminal is only suitable for one type of fingerprint entry animation, which will result in a waste of terminal storage space. In addition, the number of times the user enters fingerprints needs to reach a fixed number of times, which cannot be adapted to the requirement of the number of times of dynamically entering fingerprints.

Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various pieces of information, such information should not be limited by these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information, without departing from the scope of the present disclosure. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

In the related art, when a user enters a fingerprint template through a fingerprint sensor on a terminal, the terminal will prompt the user to place a finger on the fingerprint sensor, as shown in FIG. 1A . Further, before the fingerprint template entry is completed, the user needs to perform fingerprint entry multiple times, and the terminal will correspondingly display the current fingerprint template entry progress, as shown in Figures 1B and 1C, for example.

For different terminal models, the user needs to input a fixed number of times, such as 8 times, 12 times or 16 times, to complete the final fingerprint template. The number of image frames of the fingerprint entry animation corresponding to different fingerprint entry times is different. For example, when the number of fingerprint entries is 8, the number of image frames of the fingerprint entry animation is 8; when the number of fingerprint entries is 16, the number of image frames of the fingerprint entry animation is 16.

In the related art, in order to adapt to all models, the above three types of fingerprint entry animations including different image frame numbers are simultaneously stored in the terminal, thus causing a waste of terminal storage space. In addition, the number of fingerprint entries performed by the user is fixed. For some skilled users, the number of fingerprint entries may be less than the fixed number of times when completing the fingerprint template, which results in that the current fingerprint entry animation cannot dynamically adapt to the requirements of the number of fingerprint entries. .

In order to solve the above problem, an embodiment of the present disclosure provides a method for displaying a fingerprint recorded image, and the method can be used in a terminal, for example, a smart phone, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), and the like. As shown in FIG. 2, FIG. 2 shows a method for displaying a fingerprint entry image according to an exemplary embodiment, including the following steps:

In step 101, the fingerprint entry information of the user is obtained;

In step 102, the entry progress of the fingerprint template of the current user is determined according to the fingerprint entry information;

In step 103, in the pre-stored fingerprint entry animation whose image frame number is a preset number, determine a frame of target fingerprint entry image that matches the entry progress;

In step 104, the target fingerprint entry image is displayed.

In the above-mentioned embodiment, the terminal only needs to store the pre-stored fingerprint entry animation with the preset number of image frames, and can automatically determine and display a matching target fingerprint entry image according to the entry progress of the current user's fingerprint template, which saves money. Terminal storage space. In addition, the number of times the user performs fingerprint entry can be dynamic, which improves the intelligence of the terminal and improves the user experience.

For the above step 101, the terminal may acquire the fingerprint entry information according to a related technology through a pre-installed fingerprint sensor. Optionally, the fingerprint entry information includes information such as fingerprint area and fingerprint feature points, wherein the fingerprint feature points may include information points such as fingerprint radians and fingerprint bifurcation points that can characterize the characteristics of the current fingerprint.

For the above step 102, optionally, as shown in FIG. 3, which is another method for displaying a fingerprint entry image based on the embodiment shown in the foregoing FIG. 2, step 102 may include:

In step 102-1, calculate the ratio of the information amount corresponding to the fingerprint entry information to the preset total fingerprint information amount;

In this step, the terminal has obtained the fingerprint entry information through the fingerprint sensor, and further, the information amount corresponding to the fingerprint entry information can be counted, that is, at least one of the fingerprint area value and the number of fingerprint feature points can be counted. The total fingerprint information has been preset in the fingerprint template, that is, the total fingerprint area value and the total number of fingerprint feature points are preset. In the embodiment of the present disclosure, it is only necessary to calculate the current counted fingerprint information to account for the preset total fingerprint information. The ratio of the amount can be.

For example, the preset total fingerprint information includes: the total fingerprint area value A and the total number of fingerprint feature points B, and the current fingerprint information counted includes: the fingerprint area value a and the number of fingerprint feature points b, then the fingerprint area value can be calculated separately The ratio of a to the total fingerprint area value A is 1, and the ratio of the number of fingerprint feature points b to the total number of fingerprint feature points B is 2. Finally, the above ratio 1 and ratio 2 are multiplied by their respective weights and added together. A final ratio is obtained, that is, the ratio of the fingerprint information amount to the preset total fingerprint information amount.

In step 102-2, the ratio is used as the entry progress of the fingerprint template of the current user.

In this step, the terminal may directly use the ratio calculated in the above steps as the entry progress of the current user's fingerprint template.

For the above step 103, the pre-stored fingerprint entry animation includes a preset number of image frames, optionally, the preset number may be 20.

Further, the frame numbers of each frame of the image in the pre-stored fingerprint entry animation are numbered in ascending order according to the entry progress of the respective corresponding fingerprint templates. That is, the frame numbers of the multi-frame images of the pre-stored fingerprint entry animation are numbered in ascending order according to the entry progress of the respective corresponding fingerprint templates.

For example, the 20 frames of images in the pre-stored fingerprint input animation are numbered sequentially from 1 in the above order, and the image with the final frame number of 1 corresponds to the fingerprint template with the smallest input progress, such as shown in Figure 4A; and the image with frame number of 20 The entry progress of the corresponding fingerprint template is the largest, as shown in Fig. 4B, for example.

Then, the process of determining the target fingerprint entry image in step 103 is shown in FIG. 5 , which is another method for displaying the fingerprint entry image based on the embodiment shown in the aforementioned FIG. 2 . Step 103 may include:

In step 103-1, calculate the product of the input progress and the preset number;

In this step, the terminal may first calculate the product of the currently obtained fingerprint template entry progress and the number of image frames included in the pre-stored fingerprint entry animation, that is, calculate the product of the entry progress and the preset number.

For example, if the preset number is 20 and the entry progress is 24%, the calculated product is 4.8.

In step 103-2, the target frame number is determined according to the product;

In this step, optionally, when the product is greater than 1, the maximum integer value less than or equal to the product can be used as the target frame number; and when the product is less than or equal to 1, 1 can be used as the target frame number.

In the embodiment of the present disclosure, in order to more accurately reflect the current fingerprint template entry progress, if the obtained product is greater than 1, the integer value closest to the product is taken downward as the target frame number; if the obtained product is less than or If it is equal to 1, 1 needs to be used as the target frame number, that is, during the fingerprint template entry process, at least one frame image corresponding to the smallest fingerprint entry progress needs to be displayed.

For example, if the calculated product is 4.8, then 4 can be used as the target frame number. If the calculated product is 0.8, you need to use 1 as the target frame number.

In step 103-3, in the pre-stored fingerprint recording animation with a preset number of image frames, a frame of image corresponding to the target frame number is used as the target fingerprint recording image.

In this step, the terminal may directly record a frame of image corresponding to the target frame number as the target fingerprint input image in the pre-stored fingerprint recording animation with a preset number of image frames.

For the above step 104, after the terminal determines a frame of target fingerprint entry image matching the entry progress in the pre-stored fingerprint entry animation, the terminal can display the target fingerprint entry image on the terminal interface according to the related art.

The user can know the current fingerprint template entry progress through the displayed target fingerprint entry image, which improves the user experience. In addition, in the embodiment of the present disclosure, the corresponding target fingerprint entry image can be dynamically displayed based on the entry progress of the fingerprint template. For example, the pre-stored fingerprint entry animation includes 20 frames of images, but when the user enters the sixth time, the entry progress is reached. In this case, the terminal can directly display the target fingerprint entry image whose frame number is 20 in the pre-stored fingerprint entry animation. The intelligence of the terminal is improved, and the user experience is improved.

In the related art, each time the user performs fingerprint entry, the terminal not only displays the fingerprint entry image fingerprint, but also displays the remaining number of fingerprint entries required by the user to complete the fingerprint template entry, as shown in FIG. 6A , for example. In this embodiment of the present disclosure, each time a user performs fingerprint entry, the terminal may display the user's current fingerprint template entry progress while displaying the target fingerprint entry image, as shown in FIG. 6B , for example. Thus, the user can more clearly understand the input progress of the current fingerprint template, and the user experience is improved.

Assuming that when the entry progress reaches 100%, the user has performed fingerprint entry for a total of 5 times, and each time the fingerprint entry is performed, the terminal displays the target fingerprint entry image for the current entry progress, and displays the current entry progress at the same time. The entire entry process can be sequentially As shown in Figures 7A to 7E. Through the above process, the fingerprint entry process can be associated with the entry progress of the fingerprint template, and the terminal displays the target fingerprint entry image corresponding to the progress according to the entry user of the current fingerprint template, and displays the entry progress of the fingerprint template, so that the number of times the user has entered fingerprints It can be dynamic, which improves the intelligence of the terminal.

In one embodiment, the above-mentioned step 102 is shown in FIG. 8 , which is another method for displaying a fingerprint entry image based on the embodiment shown in the foregoing FIG. 5 . Before performing step 103-1, Step 103 may also include:

In step 103-01, if the entry progress reaches a preset threshold, a frame of image in the pre-stored fingerprint entry animation for indicating the completion of fingerprint template entry is used as the target fingerprint entry image.

In this step, a preset threshold may be set, and the preset threshold may be less than 100%. The current entry progress of the fingerprint template does not need to reach 100%, as long as the entry progress reaches the preset threshold, the terminal can determine that the fingerprint template entry is successful. For example, the preset threshold is 80%. When the entry progress reaches 80%, the terminal determines that the fingerprint template entry is completed, and at this time, the pre-stored fingerprint entry animation is directly used to indicate that the fingerprint template entry is completed. One frame image as the target The fingerprint can be entered into the image, that is to say, the image with the largest frame number can be entered into the image as the target fingerprint.

Although the fingerprint template obtained by the terminal at this time does not reach 100%, the terminal can continuously improve the fingerprint template by self-learning through the fingerprint sensor when the subsequent user unlocks the terminal or performs payment services.

In the above embodiment, when the terminal performs any fingerprint entry, if it is determined that the entry progress reaches the preset threshold, it is determined that the fingerprint template entry is successful, which further reduces the number of fingerprint entries when generating the fingerprint template, so that the terminal only pre-stores the fingerprint template. The fingerprint entry animation can meet the user's requirement of displaying the entry progress when entering the fingerprint template, which improves the intelligence of the terminal and improves the user experience.

In one embodiment, the above-mentioned step 103 is shown in FIG. 9 . FIG. 9 is another method for displaying a fingerprint entry image based on the embodiment shown in the foregoing FIG. 5 . Before performing step 103-1, Step 103 may also include:

In step 103-02, if the current cumulative number of fingerprint entries by the user reaches the preset number, it is determined whether the entry progress has reached a preset threshold;

In this step, when the current cumulative number of fingerprint entries by the user reaches the preset number, that is, the number of image frames included in the pre-stored fingerprint entry animation, it can be determined whether the entry progress of the entered fingerprint template of the user has reached the predetermined number. The preset threshold, optionally, the preset threshold is less than 100%, and may be 80%.

If the input progress reaches the preset threshold, continue to execute step 102-03.

In step 103-03, a frame of image in the pre-stored fingerprint entry animation for indicating the completion of fingerprint template entry is used as the target fingerprint entry image.

In this step, the terminal can directly use a frame of image in the pre-stored fingerprint input animation used to indicate that the fingerprint template registration is completed as the target fingerprint input image, that is to say, the frame image with the largest number can be used as the target. Fingerprint entry image.

In the above embodiment, if the accumulated number of times the user currently performs fingerprint entry has reached the preset number, that is, the number of image frames included in the pre-stored fingerprint entry animation, the terminal can determine the fingerprint template entry when the entry progress reaches the preset threshold. success. Through the above process, the terminal only needs to store the pre-stored fingerprint entry animation with the preset number of image frames, which can meet the user's requirement of displaying the entry progress when entering the fingerprint template, save the storage space of the terminal, and improve the intelligence of the terminal. .

In one embodiment, the above-mentioned method for displaying a fingerprint entry image is shown in FIG. 10 . FIG. 10 is another method for displaying a fingerprint entry image based on the foregoing embodiment shown in FIG. 9 , which may further include:

In step 105 , if the current cumulative number of fingerprint entries by the user reaches the preset number but the entry progress does not reach the preset threshold, it is determined that the fingerprint template entry has failed and any fingerprint entry images are stopped.

In this step, if the current cumulative number of fingerprint entries by the user reaches the preset number, and at the same time, the entry progress does not reach the preset threshold, the terminal determines that the entry of the fingerprint template has failed, and can output a prompt to the user to enter the fingerprint template. Failed prompt message, and exit the fingerprint entry process, no longer display any fingerprint entry image.

In the above embodiment, when the accumulated number of times the user currently performs fingerprint entry reaches the number of image frames included in the pre-stored fingerprint entry animation but the entry progress does not reach the preset threshold, it is determined that the fingerprint entry has failed, and no fingerprint entry image is displayed. The pre-stored fingerprint input animation can match the input process, improve the user experience, and improve the intelligence of the terminal.
